The New Most Powerful LP GPU In The World? 

Sapphire AMD cards are always one of the best you can get out there

But the XFX looks soooooo cool m'an and yet it's hotter...

Could it be voltages?

Makes perfect sense since these are just repurposed as a desktop gpu. Thanks a lot for the info.

So? Its not a laptop card is it?

@@kidShibuya The chip designs were finalized several years ago, but then 2021 happened, and AMD was like "people want desktop GPUs, and we have these mobile chips piling up in our warehouse, let's see if we can make this work" but they can't just tack on an encoder or more PCIe lanes just because it's on a desktop card now.

@@kidShibuya it's a laptop die slapped on a desktop PCB

@@kidShibuya Yes. it is. They can't just magically put one back onto it because they decided to sell it as a desktop part now.

yeah, gimped by design, just like the 6500xt. nah, not the new lp king definitely.

I mean, the real reason they made the card is for the enterprise sector via OEMs. selling them on their own is just a bonus.

I don't think that's true, it doesn't pack enough performance to be limited by even x4 pcie gen 3. It would have to be x2 or x1 which I really don't think they did. Lower pcie bandwidth does not mean performance impact across all gpus. The 6500xt runs Into issues with pcie only sometimes because it's at the edge of needing more bandwidth, also because the memory bus is so small.

@@SaveTheSunF1R3x i’m 99% sure the 6500XT is just a repurposed laptop GPU, which explains why it has only 4 lanes instead of the usual 8 or 16 for desktop GPU’s. the 6400 might be the same deal but idk

@@raycert07 The issue is when games need more RAM than its onboard vRAM, then you will start seeing differences as it's using the pcie bus to move texture data around constantly.

Well yes , it's 7nm vs 12nm litography :D

it's efficent but a stretch for sure since it can't even do video encoding which is quite important nowadays

@@samihyppia8472 6nm actually

@@Piipperi800 important for what. You can do encoding on cpu as well with igpu. How many people are actually creators in the first place? Don't make fake "importance". Most people will use this card for ps emulation

@@wisdoom9153 oh

And even then is bad, slower than a 1650 unless you go Pcie4.

or worse, PCIe 2.0. I have such a system, with a Haswell based CPU. They really should have stuck to 3.0 and put an x8 or x16 lane interface on this. But they didn't, because... reasons? I don't really understand why they did that.

It's not strange, it's just cheap. These cards are cost-reduced af

@@SeeJayPlayGames Its because this chip was designed for laptop first where most lower end GPUs are connected with x4 anyways and these will be paired with pcie 4.0 CPUs.

@@OTechnology idk man because the amount of copper wire, R&D, or anything they save by doing it this way might justify the move from the cost perspective, but does it worth causing people not wanting to buy it and instead go for a used RX570 etc. because it is what entry level market is like, seen with many past generations where the newest budget card is simply not as attractive as an old used one. From this perspective, the only thing that makes RX6400 worthy of buying is just the low profile and because it's brand new

Or is it because they know this card arent supposed to be a top seller so they just dont care anyway that sounds fair to me as well lmao

It sucks.I remember building my first PC around 2007 and looking at several pages worth of GPU’s all under 150$.I think I settled on a nvidia 8600GT for 90$.That card was insanely good for the price and could run pretty much anything at 1080p and 60 - 90fps.

even my “entry level” system of a ryzen 5 3600, a GTX 1650 and 16GB 3200 ram was around $700 when i built it (right before the gpu prices skyrocketed). entry level is getting more and more expensive as new games come out

i still have a system with r7 240 and i3 2120

@@iustin.29 for word processing?

@@ma-bn2fj yea :/ I feel like new "entry level" should be like $200-$400, $600-$1000 is what I would consider midrange if it wasn't like the minimum for a new parts with a dgpu setup.

right, but here he just tested with Ivy Bridge which is PCIe 2.0... so we're already seeing worst-case scenario... what's your point?

@@SeeJayPlayGames Ivy Bridge is PCIe 3.0, but let's not assume that bargain basement OEM motherboard is PCIe 3.0 certified.

Depends on the game. Some older games would be perfectly satisfied with 4GB VRAM, so you would not need to use system RAM so much.

@@SeeJayPlayGames 3.0

@@SeeJayPlayGames I've bridge supports 3.0 as long as this on a chipset that supports it.

Yeah, they really should have given this card 8 PCIe lanes and the 6500XT should have 8 lanes as well. These low end cards were really gimped from that and also not having an encoder as well.

@@Dave-dh7rt Yes but AMD also explained that the RX 6500 and RX 6400 have been designed as dedicated Laptop cards. Thus the PCIe 4.0 x4 would be sufficient. I am not sure about the encoder.

What does 4 pcie lane has to do with anything? Sorry I don't understand any of these.

​@@rrsharizam PCIe nomenclature has a version number and a lane(s) number. PCIe of version 4.0 (shorthand PCIe 4.0) is theoretically twice as fast as PCIe 3.0. The card in this video only has 4 lanes, so you'd write it PCIe 4.0 x4. And 4 lanes (compared to the usual 16 lanes many gaming cards provide) is holding back the card. Using an older motherboard with only PCIe 3.0 would reduce the connection to the PCIe 3.0 x4 (version 3 with 4 lanes) and that reduces performance even further.

@@TanigaDanae Thanks. Anyway, I'm trying to build a PC but this is far too complicated. I guess I'll just buy from the fruit brand then

GPUs this low power and performance won't even be an issue. If a nVidia 3090 isn't severely bottlenecked by a PCIe 2.0 16x interface, where multiple sources showed 5% average reduction in performance compared to PCIe 4.0 16x, then this low performance GPU will hardly have much difference even running at PCIe 2.0 8x speeds.

Most likely a non-issue for the 6400, it's a problem with the 6500XT as its on the edge of needing the extra bandwidth of pcie 4.0 due to the lanes and slow memory bus, the 6400 shouldn't need the extra bandwidth so most likely doesn't present the same issues.

@Christopher Tran lol, you're confused. Those tests are to PCIe 3.0 and not 2.0. And although 4.0*4 is as fast as 3.0*8 this doesn't have 8 lanes so is limited to 3.0*4 or in an even worse case 2.0*4 although dropping this in a system that old makes no sense as the cpu would bottleneck incredibly hard.

@@viet0ne a 3090 has 24gb of VRAM, not many trips over the PCIe lanes will be made there. With "only" 4gb of VRAM to spare, memory bandwidth starts being much more important.

@@viet0ne The issue isn't bottlenecking the GPU core itself. The issue is bottlenecking the communication between the VRAM and system memory, and if the GPU has to access something in system memory, since it is used as overflow for things like textures, it will cause problems. 4 PCIe Gen3 lanes are slower than even DDR3 800. So yes, the lane limitation is a bottleneck and it's not hard to fill up 4GB of VRAM. Not to mention, you don't even need to fill it up. Some games will be problematic even when the VRAM isn't full. It becomes an even worse issue with PCIe Gen2, which there are even 4th Gen Intel systems using PCIe Gen2. Anything with an H81 chipset is limited to PCIe Gen2. So, yes... this is a big issue. And it's made even worse by the 64-bit bus bandwidth.

came here to point that out as well - the A2000 is basically a SFF 3060

RTX A2000 pricepoint is nowhere near RX 6400.

​@@3dr14ng4 sure, but I'm not claiming that - the video is titled "The New Most Powerful LP GPU", not the "most affordable" or" best value" just my 2c

@@headhunterj3 Well, glossing over the fact that he did not have one on hand, I'd like to point out the 6400 and the 1650 directly compete because they are both low power cards with low profile configurations available, made within the last ~3 years. Edit because forgot some words.

ah yes that reminds me of the shithole hp forums, the plan for me was to buy a prebuilt put a 1050ti and call it a day, so i bought a prebuilt hp with i5 2400 like 8 years ago, and it worked fine now i needed a gpu so i know a bit about pcs so i asked on hp forums what kind of slot it is obviously its 16x but is it low power or full power, they said they dont know, upon asking the second time they said its limited 8x at 35w, which i found strange so i thought they might know better than me, so i removed the cpu and ram hdd and bought a 1155 mobo asus deluxe(the fucking most expensive one probably :D) and a new case, new psu and a r9 280x, and the pc worked fine till the r9 and the psu died, so 2 years later i switched the stuff back into the prebuilt chassis and mobo and said fuck it ordered a used 1050 ti and guess what it fuckin' booted on the first go. i just threw 400 dollars down the drain for nothing.

Similar with may with my first and my second pc. Theyre Pcs from the bank where my Fater works. Because they replayced them evry three years when the guarantee ran out ive got them fro free. The second one was an HP elite desk g1 with an i5 4690 and 8gb ram. And originally an Quadro NVS 315. But that thind is so bad at games i replaced it after a maybe 2 Years with an gt 1030. Was way better at gamimg. For example from about 7 Fps in 720 low inf fortnite to about 50 fps mid in 1080p. But i still neded more than 2 gb of vram so ive built an entire new cusom pc in 2021.

@@ExperiencersInternational but that isn't what the 6400 is supposed to be used for. It's supposed to be put in computers with low end psus.

I'm seeing the prices drop on Ebay steadily. Can't wait, as I'm thinking of upgrading to one. Would be amazing to have a LP GPU with power close to a 3060, while also maintaining it's wattage usage below 70w.

it's not just laptops. Old office computers like the ones he used have it too. It's like people forgot that intel QuickSync Video has been around since 2011, baked into any half-decent processor ever since (not Celeron). Though, TBH, Handbrake does NOT like my Haswell, and simply fails to encode, but the Xbox recording interface doesn't seem to mind using it. Yes, AMD left out VCE for their low-end... but Dawid didn't mention that QSV could still be used. That's kind of a glaring omission.

@@SeeJayPlayGames It also doesn't take into account that most people don't record their games.

What cheap sff pc has pcie4?

I doubt it can saturate a gen 3 slot. Won't make much difference if any.

Yes, it's like they are made to be in a system with good case cooling, but most LP cases don't have good case cooling. I have a Radeon RX 560 that worked great (relatively speaking) in a full tower case I used it in for a while with very good cooling (it was an old case, but I replaced the old broken down fans with new Noctuas when I repurposed the case). Then I put it in a low profile case after I didn't need it in the tower anymore, and it overheats. I could do something with a low profile case to improve cooling, but that's kind of a pain.

But cost way more

Some quick googling suggests the A1000 is a laptop gpu? And the desktop cards start at A2000, can you point my in the direction of a desktop A1000?

The problem with your suggestion though is you can't really buy the RTX A1000 as easily as the RX 6400.

Did you manage to find out the cause, tho?

@@Kraven83 Everyone on the IT team is convinced it's the new Samsung EVO ssd (like what), but of course I have no issues on my home machine. This being at work, this isn't really in my job description to look into and so it won't be solved.

This GPU chip is a laptop "dedicated" GPU with minor changes, and in a laptop the decoder/encoder is in the iGPU anyway. In this case they are saving a lot of money because they did not design a "new" low end chip, they just re-purposed the chip they designed for laptops

Though who is going to have enough money to buy a motherboard with pcie 4 but not enough to spend an extra little bit on a gpu. So most of these gpu's will land up in older systems. Which is unfortunate.

Using a system with a mediocre old CPU also didn't help. I did not understand that, he should have something modern at home to test it properly..

@@xPandamon Theres plenty of benchmarks with high end CPU's. This is a more realistic use scenario

@@jasonjenkinson2049 In a less powerful PC your CPU will generally be the bottleneck. He talked about comparing it to the 1650, which needs a better system to really make sense.
