Benchmarking the AMD Radeon RX Vega 64 8GB and High Bandwidth Cache Controller (HBCC) in 15 games using an average gaming PC in 2023.
Support Iceberg Tech: / icebergtech
With VRAM becoming a point of contention around graphics cards these days, AMD came up with a solution for those who felt like 8GB wouldn’t be enough in the future. In fact, they came up with this solution about 6 years ago; High Bandwidth Cache Controller, or HBCC, was a feature of the RX Vega graphics cards when they launched in 2017. This enabled the use of system RAM instead of VRAM, meaning that if you had enough spare RAM in your PC, you could dedicate as much as you liked to your GPU.
HBCC was mostly ignored at the time, as 8GB cards like the Vega 64 weren’t exactly being overly stressed by games of the day, but things have changed in 2023. Does HBCC work as advertised? Does it help the ageing GTX 1080 competitor run today’s memory-hungry games? And why wasn’t it more popular?

@ninele7 10 месяцев назад

It is important to note, that some games like Halo and Hogwarts Legacy when under VRAM pressure will swap out some textures from VRAM and produce worse image than intended. Enabling HBCC might lead this games to not swapping textures and keeping image quality but at cost of performance. So when testing such features it is important to check that image quality is really equal.

@wayland7150 2 месяца назад

As I understand HBCC it's about increasing the available VRAM which one would expect to improve texture quality. I might have expected it to improve 1% lows but I would not expect maximum frame rate to improve. It's a shame it's no good in Warzone because that's one game that really needs more VRAM.

Suspect HBCC mainly helps in cases where the game does a bad job at vram management and allocates vram that it doesn't use much which potentially lets the caching management take up some of the slack better than a normal setup.

@livingthedream915 10 месяцев назад

@wnxdafriz 10 месяцев назад

honestly.... vega was designed as an all in one heavy compute card essentially its a workstation or gaming card --- HBCC most likely helps with large data sets where they need the memory, some examples would be comparing data that involves weather patterns i believe

@olnnn 10 месяцев назад

@@wnxdafriz Probably, the card isn't really fast enough to make use of more than 8 GB of VRAM in most games anyhow (not to mention the 16gb radeon VII), and few games at the time were even able to hit 8gb vram usage so it makes more sense for productivity use. Even workstation cards don't come with HBM these days though so I guess it wasn't worth it enough in the end over just putting a bunch of GDDR on them instead and reserving HBM for datacenter stuff.

I have a Radeon VII (otherwise known as Vega 2nd Generation) and it still kicks ass. Love it a lot and don't have any regrets. Even without overclocking or anything, having the 16GB HBM2 memory has ensured that memory bottlenecks aren't really an issue for me (at 1080p). Having this option in HBCC to further expand it into the future makes me really happy. I haven't felt a need for it yet.

This is actually interesting for other applications, rather than gaming. If you are trying to run a LLM locally (a model like chat-gpt), then you would run out of VRAM pretty quickly on bigger models. If you could expand the vram using the regular ram, it would allow you to run bigger models on a cheaper card... Issue is, the support for ROCm (cuda equivalent for AMD) is pretty bad right now

@iancalandro8180 10 месяцев назад

Im curious how this will handle v-ram intensive production applications, stuff like Stable Diffusion for example. You can run SD on AMD now through DirectML, and I have thought of trying that on my Vega 56. Might be a good motivator.

@IcebergTech 10 месяцев назад

Never tried running Stable Diffusion locally tbh. What kind of workloads would cause it to use a large amount of VRAM? Just, like, regular images? Or would it have to be particularly high resolution ones?

@iancalandro8180 10 месяцев назад

@@IcebergTech Stable Diffusion in general is a very V-ram intensive application, but generating larger images and generating more images per batch (multiple at a time) require more vram. I have found that 8GB cards like the 1070 and the 1080 can generate images from anywhere between 512 x 512 and 1024 x 1024 (though usually closer to the lower end) but V-ram usage goes up exponentially as resolution increases. I don't know if Stable Diffusion on AMD is any more or less V-ram efficient through the DirectML backend. I feel like Vega can handle it, but I did try running SD on an RX 580 8GB which resulted in massive temperature spikes on the core and forced a system shutdown. It could be a 580 specific issue, or it could be a "GCN runs hot and hungry" thing. I unfortunately don't have any Navi stuff to test that. If you're interested in getting SD running locally there are two ways to do it: 1: Using the DirectML backend. This is the only way you can run it on Windows right now. 2: Using the ROCm backend. I haven't tried this, but it requires that you use Linux or WSL. I have heard that Arch based distros (like Arch, Manjaro, and Garuda) are the easiest to set this up on.

@Winnetou17 10 месяцев назад

Oh, I'm definitely curious to see how this works with 32 or 64 GB of DDR5 RAM at 7200 MT/s with low latency (and 2 sticks only, DDR5 on 4 sticks is horrible at the moment). Also, I think that HBCC can help properly only if the game also knows to load things sufficiently in advance (so you don't need it instantly, you're not so succeptible to latency). Or simply, like someone else noted, maybe having a lazy approach of leaving things in memory if there's space, and having this more means that you might benefit from that when those assets are reused. In any case, it does look like the game's programming (or game + driver) does matter. I guess the ultimate test will be the (very?) few games that will have high enough textures that even 1080p might need more than 8 GB of VRAM. Or that have 1440p running well enough to be used by Vega 64, while also having very high textures. It's kind of a bit un unfortunate that the market itself, the developers, are actually taking care to only push over 8 GB of VRAM when it's actually needed, since soooo many people and cards have 8 GB, not caring for that would destroy the performance on too high of a marketshare, so to speak.

@Rocky-bz8wr 10 месяцев назад

Great video thank you. When I had a Vega 56 flashed to Vega 64 bios I used to undervolt and be able to push the core and vram to really sweet clocks. My card allowed settings of 1800Mhz core and 1150Mhz vram max. I ran it at 1785 core and 1100 vram. In the last of us part 1 core would run 1778Mhz vram 1100Mhz and fps it would get 68-82 FPS. I was extremely happy with that result. Settings 1080p mostly max except shadows. Power usage though 258-270 watts which is pretty high. If I locked at 60 fps vsync power usage dropped quote a bit down to 126-155 watts weird lol. In Starfield I just wanted to say on AMD ryzen 5000 cpus turning off AMD SMT gains you quite a bit of fps at least it does on my 5900x. As for fps for Vega in Starfield I'm not sure as I now have a 7900xt card. My Vega is in its box waiting to be used by someone again hopefully soon.

I spec'd it with a 6700k 2 Rx480's 8GB and a few other good options like the cd-drive. I've pretty much replaced everything but the 6700k and it's factory AIO liquid cooler. -i7 6700k @ 4.7GHz @1.4V -Vega 64 Limited Edition Liquid cooled 8GB HBM2 (which I snagged off marketplace for a deal.) with the memory over clocked to bump up the bandwidth from 483.3 GB/s to 555.5 GB/s. (helps HBCC I think) cleaned it up and replaced it's thermal paste and shoehorned it into the chassis after some modifications to the case and removing the lower drive bays and trimming some plastic. -swapped out some of the old fans for some Artic Slim P12's , 2 on the CPU AIO as a push pull and one on the GPU AIO as a push, all acting as exhaust creating a nice passive intake using the factory side vents. -4x 16gb sticks of HyperX fury GDDR4 RAM running at 2400MHz (MOBO limited, 34/3600 MHz capable iirc.) for 64GB total physical memory. -For storage I got rid of my old 256gb M.2 drive and 1.8TB HDD combination and replaced it with an Intel DC P4608 series PCi-E SSD. It's an older enterprise grade data center SSD that has faster read/writes on average than any M.2 I could have gotten to work ( non NVME.) and it has insane random read/writes paired with high endurance. It's a 6.4 TB drive but it's essentially 2 3.2TB discs on one drive. So with that in mind I decided divvy an even page file cache from each of them to tune of 32GB each. So with my 64GB of GDDR4 plus the allocated combined 32gb+32gb I now have a useable 128GB system memory. Once I got that sorted I moved onto the HBCC. I then allocated 32 GB of system memory to be used as VRAM cache. When I open task manager it shows dedicated GPU memory is 32GB and shared GPU memory is 32 GB but total GPU memory is 64GB. I'm not sure where it pulls the memory from, either it uses the RAM physical memory then the RAM is supplemented by the file cache or vice versa. Truly an alien piece of hardware now.

worth mentioning is also the fine-vine technology that applied here quite niecely. If you would retry the tests, the vega56 is now pretty close to 1080 in most of the titles.

Ratchet and clank is strange, I went from 35fps to 45fps when upgrading from 16gb to 32gb ram. My settings were 1440p native with full rt on rx 6700xt and 5600x. That is a massive almost 30% increase by just upgrading ram. Gpu power draw also went up, indicating that 12gb weren't enough for those settings. That is probably why the gains were much smaller with RT disabled. More like 10-15% at max settings 4K with fsr performance. I observed the same thing in spider man, 4K fsr balanced with RT, I went from 45 to 70fps, by just upgrading RAM, crazy.

I wonder if HBCC would work better on a DDR5 platform. Do you have a system you could test that with?

@Antagon666 10 месяцев назад

It shouldn't... PCI-E bandwidth is far lower than typical DDR4 bandwidth. Latency of DDR5 is slightly worse or at best same (typically).

@0Synergy 10 месяцев назад

Would love a retest with a Radeon VII and tuned DDR5(the fastest you can get) with a 7800X3D, kind of interested to see the limits of HBCC

@AliShaikh_744 10 месяцев назад

But a Radeon VII has 16GB VRAM so almost no game will be able to use that much VRAM hence HBCC will basically be useless

@0Synergy 10 месяцев назад

@@AliShaikh_744 Ah shit good point. Fuck why do they put this feature on the cards that dont need it? Like imagine this on the Nvidia cards of last gen that would have atleasted helped.

@MLWJ1993 10 месяцев назад

@@0SynergyRadeon VII is more a heavy compute card. You might get good results out of HBCC running non gaming workloads on the card. For simple gaming the GPU is kind of bad value for money.

@olnnn 10 месяцев назад

Maybe but it would still be limited by the theoretical max 16GB/s speed of PCIE 3.0 while one channel of DDR4 3200 has a bandwidth of 25.6 GB/s so the PCIE bus may already already be a bottleneck in the current dual channel DDR4 3600 system and higher bandwidth ram might not help a lot more but idk. (Idk what the actual bandwidth is in practice though)

@ZackSNetwork 9 месяцев назад

The 7800x3d only needs 6000mhz DDR5 and just like the other Zen 4 CPU’s it doesn’t benefit when you go higher.

@aboveaveragebayleaf9216 10 месяцев назад

Probably just a case of lacking software support. I could see the technology doing well if implemented well. Could also depend on if there is a cpu vs gpu bottleneck.

@arenzricodexd4409 10 месяцев назад

The tech have it's issues. AMD did not solve that and just release the tech as it is. That's why HBCC being turned off by default in AMD drivers.

@VikingDudee 10 месяцев назад

Yeah I have a Vega 64, pretty good card and it really benefited from undervolting, I tried the HBCC in Forza, while it worked, I didn't get the notice of running out of video memory, the game would end up loosing so much performance over time it would end up in the teens or even single digits if left idle in freeroam. Call of Duty Modern Warfare 2 does play well on low to med sitting on the card, but that game if you got the Vram it will use that vram, enabling HBCC will also seem to make things slow over time, I didn't do much testing with it myself, I just kept it off as I didn't feel like restarting my game every 30min to an hour.

@atiradeon6320 10 месяцев назад

If you want a good showcase for HBCC in a game check out Greedfall in the later cities. It allowed me to keep textures on Ultra and have a smooth gameplay, it was maybe the first WOW moment for HBCC back when I still had a V64. Without it the game would run out of VRAM as you kept playing and would murder the frametimes.

@jacksonbtb571 9 месяцев назад

This would be interesting with quad channel ddr4 as well. I got quad channel ddr4 @ 3600 in my x299 pc. Sometimes I really dont know if quad channel matters at all for gaming numbers, but maybe the extra bandwidth could help here?

@chillerfive 10 месяцев назад

just got an upgrade in the mail and uninstalled my vega56 and searched for vega content and saw your video uploaded just a couple hours earlier; what a coincidence. I'm impressed by the relevancy of titles benchmarked. Usually I'm left scratching my head why people would choose a set of two dozen random single player titles of the last 5 years that together demonstrably have a couple thousand unique players per month. Your mix of games is perfectly relevant or interesting to me. Like how fortnite is usually a good indication of unreal engine performance.

I recently got a Vega 56. My main game is COD Warzone and I was getting huge lag spikes. The used system I put it in was also new to me so I wasn't sure the issue. I was able to fix it by dropping the in-game VRAM usage to something low like 50% or 60%. Now it plays smooth. I thought maybe this video would show that the HBCC would help, but I have my fix anyways. Hope this helps someone out there.

I doubt it, even dual channel DDR4-1600 (yes that speed exists in the JEDEC spec) has significantly more throughput than PCIe 3 x16, but it might depending on the software and HW implementation: does the GPU use DMA or does the data need to be elaborated on the CPU? because this 2 scenarios i would expect to behave differently at varying throughput and latency

@@rubenfasola5402 there was nothing scientific about my experiment sadly, and I probably should have turned it off and on to compare, but for some games I can definitely tell the 0.1% lows must have been better.
