Good to see a RU-vid channel doing PC harware bench marks with a focus on Sim Racing. Most will focus on Cyberpunk/RDR2/SOTR in a 1440p single screen setting but sometimes you want to know what a potential upgrade can mean for a triple screen 1440p setup in games like iRacing and ACC. I remember thinking moving from a 5600x to a 5800x3d was not worth it until I stumbled upon a video of someone playing ACC with the same GPU as me but the 5800X3d as a CPU. He was hitting 40 to 50fps more while using the same settings (I was on a 34 wide then). For the people wondering about the performance of the 7900XTX. I did a quick online test session at Valencia using almost the same settings (some still left on Epic) and in the dry it was between 145 and 160 fps (had it locked at 160). Also checked to replay on the same track of a full grid race in cockpit mode. One in the rain and one dry. The dry race was still between 145 and 160 fps. Rain was a little harder with some dips to 130 on the pit straight. That is okay for me because I always lock to 120 fps. Now go give this man a sub!
I have a 5800X3d and a RX6800XT and in I racing with triple 32”, I am always in the 50’s at the start of races or rain or night. Would the 7800xt help or is it CPU blocked.
@@racekar80 I'd say get an Nvidia card in the same price range. I'm also on a triple 32" playing iRacing (1440p) with a 7900XTX and am dipping into the 60's when it rains at the start. I like AMD and when it comes to non RT performance, the AMD GPU is going to be the best beng for your buch in terms of perfomance. iRacing is different because there is a setting that AMD user can't use and it impossible for AMD to compete in this game. Sadly, I bought my XTX before I got into iRacing.
Fascinating stuff! Would love to eventually see that CPU scaling video. Currently running triple 1440p with a EVGA 3080 12GB (non-TI) and a 12600K. Curious to see what extra performance (FPS) a 13/14600K or even 13/14700K could provide! Keep up the great work! 🙂
thanks for this. nearly impossible to find sim racing benchmarks on triples. I wish you had 7900 XTX to compare it to 4080 Super. I was on the fence between the two but ended up getting 4080 Super since I heard it is much better with VR (which I also use) and triples.
It's a lot of work to test triples, so I can see why no one else wants to do it haha! I'm looking forward to testing a 7000 series Radeon, hopefully sooner than later. But I'm working on VR benchmarks with the 4080 Super now :) What did you upgrade from?
I had a Ryzen 5 7500F + 4070 Super, chose to upgrade to a 7800X3D after many stutters while using VR in SimRacing and everything's a lot smoother now. CPU is a lot more important for SimRacing than for regular gaming needs.
Thanks to the algo, I haven't even looking for GPU content for a few weeks, but here I am. I need a new laptop and don't have desktop. Never had gaming spec stuff. My next monitor will need to be the 57" dual 4K Samsung. It's so much more affordable than the watches and cars I lust for... What laptop specs might run dual 4K at 100 FPS in iracing at a detail level with 4K? Else, how might it look dialed down to 1440P leaving it to the monitor to scale up dumbly or cleverly? I don't know how clever they've made the monitor, but Samsung does have upscaling stuff in-house.
I do not have experience with gaming laptops :( Performance is worse compared to desktop (maybe -20%?). This website does gaming laptop reviews: www.notebookcheck.net
Thank you for this! Helps me choose a GPU for future proofing my PC setup. But for now I think my 4070Ti will hold, but will wait for the 4080 Supers to sale on marketplace in the near future.
@@greenops No, because we'll likely see 5090 and 5080 launch first, and those are overkill for 60fps requirement. Next-gen mid-range and entry may be a year away.
@@BenchmarkOdysseys Well, the monitors will support 144hz, and that would be preferred, 60 FPS was more meant to be my floor. Would you wait or go for it?
@@BenchmarkOdysseys yeah so just wanted to give an update on my switch to 1440p with a 4070ti (12gb) and triple monitors on iRacing. I get an average of 80-90fps on the higher end and drops to 50s in the 1%. I was really expecting 3080ti results but was really let down. I switched back to my 1080p monitirs shortly after making sure it wasnt a driver issue or GeForce update issue. Windows was up to date. Idk why i got such low fps. My only guess can be that the memory bus on the 4070Ti being a 192bit bus is not meant for triple monitors. On the other hand, the 3080ti has a memory bus of 384bit bus which is why it shines. Im sure now that 4k triples with a 4070ti is not ideal.
Good video, nice work. Just want to add that the foilage on the new or renew iRacing tracks is just frame killer. Try foilage on high on Okayma with 30 cars with your setting, (that are the same that I use, on 5120x1440p with a rtx 3080) and you will see what I mean. I had a race there full of stuttering just because of the foliage. Hungaroring is another with foliage issues ! Maybe the 4080 have enough power but not the 3080 Ti.
Thanks mate! I'm working on the iRacing video now, with detailed 'per track' results. I'll add notes about each track's design (as far as I understand them), to help us understand what impact there may be.
Well most likely reason why 3080ti performed so well at certain scenarios compared to 4080 super is because of higher memory bandwidth. 3080 ti 384bit memory width resulting in 912gb/s total bandwidth 4080 super has only 256bit memory width leaving 736gb/s total bandwidth I guess certain scenarios favors this spec of gpu's, where the bottleneck becomes memory management not the capacity. Talking about vram capacity it might also nudge the performance a bit in case where 3080ti getting close to ~80% ish range, for anyone wondering, gpu's never have 100% vram utilization, windows always leaves some headroom for background stuff. For example acc triple 4k scenario where the 4080 super has sizeable framerate advantage makes me think that vram capacity is the main bottleneck, if you check other triple 4k test you did 3080ti either matches (which is super impressive) or have very lean ~10% disadvantage despite being 30% slower in "normal" gaming tests. Very good test and super happy you tested triple 4k res as i use it myself, im currently using rtx 3090 so extra vram is super helpful here. Im actually very surprised that 3080ti had such close battle in this resolution. I guess in this case 4080 super is absolutely not worth it and is barely a upgrade, its either 4090 or rtx 50 series.
Yeah, the 4080 is really underwhelming, I think I'm gonna keep by 3080 till the next gen comes. The only good high-end GPU in this generation is the 4090 unobtanium
@@d.o.5238 4080 (super) is awesome for "normal" gaming especially if you are upgrading from older gen like rtx 2080, but in this case its just not enough. 4090 is awesome but for some reason it got expensive, i remember when it was available for ~1600€, now it starts from ~1850€ despite aging as time goes on. AFAIK rtx 50 series is coming out this year, Q4 so its best to wait for new gen imo as that will be a monster generation
Same card I bought for a rig I’m building. I’ll be using a 14700k. Heavy Photoshop user, and using Premiere Pro also. I have the original EVGA 3080 with a 10850k now.
I'm impressed with the card! Although I'm only measuring a 1% difference between the BIOS switch of Silent and OC. But there's lots of potential to manually clock the GPU/memory higher because this exposed copper heatsink is one of the best out there.
My guess for the root cause of 3x1080p anomaly is that the old AC engine is severely CPU-limited which results in 4080 not being fed with enough stuff to render in time, dropping the clock speed while being idle, and ending up with worse performance. It doesn't happen with a single screen 4K because that mode is less CPU-intensive and you don't hit that CPU bottleneck you hit with triple screens and a big grid Nords replay. At higher triple screen resolutions, the GPU has to render more pixels and doesn't get idle for long enough to drop the clocks. I think if you set Power management mode option in Nvidia control panel to "Prefer maximum performance" it will stop dropping the clock speed when idling
Thanks mate :) I think I will hold off on VR benching the 6700XT until I have the 7000 card, it will make trouble shooting and data validation much easier. Plus I can get double the results for same system setup.
Good job on the channel. It's very informative. I end up watching a lot of your videos. @benchmark Odysseys I am trying to build a PC for sim racing, mainly ACC and iRacing. I want to run it on 4 K in all maxed-out settings with at least 120 fps, as I will be using my LG LED TV as a monitor. It is 4 K 120 hz. Can you please share some insights on what CPU and GPU you will pair up?
Thanks for the compliment :) Glad to hear my videos have been helpful to you! I can totally provide 1-on-1 help and recommend a new PC system build for you. It is more complicated than can be solved on RU-vid comments. You can fire me an email at benchmarkodysseys@gmail.com
You should be running a 13 gen+ intel on windows 11. I believe 10 doesn't have the ability to fully utilize the amount of cores that new processors have.
looks like a 3080 + 5600x combination ia gonna be fine for a 1440p x 3 setup for a long time.... unless untill upcoming ac2 evo is too demanding on hardware.
Great video. Nice to see some benchmarks for sim racing titles, and particularly for triple screens. For triple screen in iRacing, do you have SMP enabled for the nVidia cards?
Yes, SMP was enabled for the Geforce cards. It's not a major performance changer, but does tilt some scenarios into it's favor compared to Radeon without it. Thank you for the sub! Cheers :)
@@BenchmarkOdysseysthanks for the reply. When I was running triple screens with an i3 9100F, I found it made a significant difference. Lol. Was obviously CPU bound.
Thanks for the work. About those anomalies, do you use DDU going to AMD to Nvidia and vice versa for those benchmarks ? Might be the reason if you just have all drivers installed and just plug the GPU then. It might corrupt files and create anomalies on how the GPU behave.
You're welcome, and thank you for watching! :) I decided to run separate NVMe for AMD and Nvidia, so I just swap out the cards and SSD at the same time.
Thank you :) I'm working on the iRacing video which has more detailed results. It appears that the 4080S is actually 'too fast' for the 13700K in several situations, and the 4080S often struggles to get +80% because it's waiting on the CPU. The other sims I've tested are less CPU-focused with their render/physics engines, and as a result, they lean into the GPU more. So, unfortunately, the GPU Busy is a moving target that changes per sim... and your CPU matters!
I was testing a 4090 ( with an i9 13900k and 64gb ddr5 ram) and had similar very frustrating and disappointing experience in AC. The utilization was %50-75 compared to my old 3080ti and the performance was nearly the same. I do play in VR that has a high resolution ( 4330x5100 per eye) so its like the triple 4k in pixelcount. I ended up not wasting my money on a 4090 and bought a 4080super. I reinstalled windows and the game and finally, my utilization is better but the performance uplift is not like I have seen online. it's around %5-20, not %35-50 what I was hoping for. Very disappointing. I do understand it's an old game and not much can be done about it
The Radeon xt and xtx had Stutters with AMS2 and. rFactor2 This was paired with a 5800x3d btw It was so Noticable that I returned both and bought a 4080super
@@BenchmarkOdysseys for sure test them please. I'm Coming to the conclusion that it's either the Drivers or.. .. the Adrenaline software there causing the stutters. Because I uninstalled Adreneline and re installed drivers only and the Stutters went always for the most part! I'm gonna sub and look forward to your own findings. I even tried to install older drivers from 2023 and still had the stutters.
Nice video,im have a 5800x3d ddr4 with a 3080ti fe for iracing with triple 32 1080p! I was thinking about a 4080 card but maybe its better too upgrade too a 78003xd ddr5 and keep the 3080ti fe! Do i get much better performance then,what your thoughts about it?
Thank you :) 3080ti is plenty for Triple 1080p! I'd wait a bit longer before a CPU upgrade, because the 5800X3D is still a strong CPU. AMD's next-gen should land this coming Fall, and that 'should' provide a big enough uplift to entice 5800X3D owners. We'll see!
Great vid, really helpful. I am currently planning on my first pc in 20 years and my first simracing rig. I want it to have 3 screens, and i am wondering if 4070ti super + Ryzen 7 7800x3d would perform well enough with iracing?
Thank you :) And welcome to sim racing! I like that combo of GPU and CPU. You should be able to achieve great graphics settings and smooth performance, perhaps even better than what I showed with the 3080ti.
Thanks for the reply! It is so many options and the naming's of the gpu/cpu stuff is a bit confusing sometimes, and depending on the store the price might not even tell the whole truth. Can't wait to finally pull the trigger on this one!
Correct me if I am wrong, but there is absolute no way to be able to run triple 4k @ 144Hz since that will max out the maximum resolution for the card? So if I were to have a triple (quad actually, with one at the top) monitor setup, should I just aim for getting maybe all monitors as 2k instead?
Great question. If you were looking to increase the FPS, you can: (1) Decrease the image quality settings within each simulator, such as world detail, car detail, track textures, etc. I perform my testing at mostly 'High' settings but not maxed out. Lowering these settings could make the objects around the track more simple, reduce the complexity of your opponent's car, dull the environment lighting, and things like that. (2) If the simulator supports it, you can enable DLSS or FSR which will render the sim at a lower resolution, and then upscale the image to your monitors running at 4K. This technique will produce graphical anomalies, usually subtle but always present. I've noticed the red/white rumble strips blurring into the asphalt, ghosting of your opponents cars, and smearing of the digital gauges in your car. Running Triple 4K will mostly affect the GPU, but there's still a increase to the CPUs burden. I have seen some unusual results within iRacing and Triple 4K with the 4080S. I'm trying to validate the results and have a more detailed video out in a few days. Using an Nvidia card and enabling it's Surround display with G-Sync, and that may present the smoothest racing experience. I believe it's possible to still have a 4th monitor, but that will take some tinkering. I have yet to test a high-end Radeon with Eyefinity and FreeSync, so I cannot recommend it until I try it first hand.
Thank you! I'm working on a VR video right now... I think it will be a comparison between the 3080ti and 4080. The graphs will be much different. I snuck a glimpse of what they could look like at the end of the this video ;)
If you're itchy for more performance, my testing suggests a 20% uplift from 3080ti to 4080s with Triple 1440p. Personally, I don't think that's worth the price. So I suggest waiting to see the RTX 50 series Q1 2025.
@@BenchmarkOdysseys Maybe it’s better to go for the 4090,I can find one for 1800€ .I think for simracing would be good for next two three years.My biggest issue is on wet conditions,I have a massive fps drop.What do you think?
iRacing has made recent changes to graphics for Wet racing; I expect them to introduce further optimizations this season. As for 4090, yes it is the best right now, but it launched 20 months ago and we are just 6 months away from 5090 and/or 5080. Those will likely be difficult to acquire and expensive, but perhaps +25% faster than 4090. Only details available now are rumors.
@roadrunner_77 While using a 5800X3D? I worry that you'll become CPU bottlenecked, perhaps even if you buy the 4090 today. But especially in the future as the simulators evolve in complexity. Bleeding edge components require other top-end components to perform. For example, it doesn't make sense to buy a 14900KS and use it with a B760 chipset and mediocre RAM. You pay extra for the fastest Intel chip, but you cannot tap into the elite performance when paired with mid-range parts. You can email me at benchmarkodysseys@gmail.com if you'd like to explore this in depth.
So witch video card and cpu and motherboard are the best for iracing and assetto corsa competizione and trippels on 1440p please tell me so i can build my PC
It depends on your budget, desired FPS for your monitors, and how 'future proof' you want your new computer to be. You can send me an email if you'd like to discuss in more detail. My email address is found in my channel's 'About' section :)
I have a 4080 and trying to decide if I should do triple 1440p or do triple 4k. Based on this I’m inclined I can run triple 4k and a decent frame rate. CPU is a 7800x3d. Can anyone chime in?
What size monitors are you thinking? My triples are 28" and that's a bit small for all the detail offered with 4K screens. But my monitor stand is on wheels, so I can move them to my desk and use for general computing. Most people think 32in and larger is where 4K shows it's advantage over 1440p. Performance wise, I think the 4080 can pull off triple 4K, perhaps with some small sacrifices with graphics quality. If you are able to run Gsync or Freesync, that may smooth out the experience, although it's not always easy to set up.
@@BenchmarkOdysseys hmm yeah true. I think what it’s gonna come down to is do I want to have high frames at 1440p or moderate/low frames for a prettier game. Hmm it’s a tough choice ngl
Damn, sorry to hear about the card. Tbh, I think the 3070 is still great for Triple 1080p. Nvidia refuses to drop prices on new cards, 4060Ti is about the same performance as your 3070. Newegg shows the cheapest 4060ti @ $385, and looks like used RTX 3070 on eBay go for $300 + shipping. I think the 'best-bang-for-buck' is probably a used 3080 10GB, which at $400 presents much better value than a new 4060Ti or original 4070, both of which will be slower than a used 3080 10GB. Frustrating, I know. Good luck on your hunt!
I’m curious about comparing the 7900xtx vs the 4080 super, does IRacing favor Radeon or nvidia? Like running triple 1440 and a 4th monitor for apps/ or other things. Looking to build a new sim pc, upgrading from my 8700k and 1080ti single 1440. Thanks.
@@youngbeliz6177 My triples are Gigabyte M28U IPS 4K 144Hz. Performance is acceptable, no quality issues. There's a bit more smearing/ghosting than I expected.
32in 4K will have a much tighter dot pitch, therefore, better image quality. But you'll need top-end components to achieve +60FPS across all sim titles. New ones like Rennsport and Le Mans Ultimate are even more demanding than AC or iRacing.
@@rcdb4160 Ah, the best available ;) Refer to Monitors Unboxed and rtings for monitor reviews. My only advice is that 'ghosting' or smearing behind the cars is perhaps the most annoying thing with gaming monitors. It appears differently depending on the panel technology. And it is exaggerated with DLSS and other frame generation technology (which struggle to correct the 'always forward motion' of driving). Good luck on your search!
@@rcdb4160 There are options under $1000, like MSI Optix MPG321UR or BenQ MOBIUZ EX3210U (I have no experience with either). You will also need a monitor stand to support them, from the likes of AdvancedSimRacing or something you make yourself. The 'footprint' required for 32" is significant. Most people go with Triple 1440 at 27" because it's cheaper, smaller, and delivers +90% of the experience. I only have 27" 4K for benchmarking purposes.
lol yes! I've already tested ACC with 7900 XTX and published a video for that analysis. iRacing has been more tricky but I think I found a way to present new data. Stay tuned!
