It looks like the 'real' /affordable RDNA3 + next gen NV desktop launch won't launch until September. Thoughts?

There's probably a case just to get the RTX 4060 TI for some games at 1080p:

It's the most demanding 1080p game I've seen I think.

I could buy a used RTX 3080 TI for £540 at the moment. Glad I waited.

The only thing holding me back is wondering if used /new prices of the RX 7900 XT are about to fall.

Any tips on undervolting a RTX 3080 TI if I do buy one?

Ideally would like to keep the power usage at 300w max, because my power supply isn't the highest end (Seasonic 650w Prime).

Looks like AMD is finally readying Navi32 GPUs:

I imagine the performance of the 60 CU part will be similar to the RX 6900 XT, so I expect it to be called the RX 7800. I suppose they might be able to call it an XT if clocked high enough, but I doubt it.

AMD still has some RX 6900 series cards to sell, so I expect they will want to sell these off first.

So, finally what looks like credible news on Navi32 GPUs:


Top product is 60 CUs, so perhaps ~20% faster than a RX 6800. Maybe close to RX 6900 XT but only with super high GPU clocks (clockspeeds unknown).

It seems a pretty good bet that they will launch these cards alongside FSR3 as this will significantly boost sales, so I reckon it will be September for both launches.

It's hard to see much appeal to the 60 CU variant without offering FSR3 - Which I think it will be exclusive to RDNA3 cards. I guess they should run reasonably cool also?

Maybe there will be price cuts to the RX 7900 series cards by then, also.

I wouldn't hold your breath for a Navi31 70 CU consumer GPU version, as the 70 CU dies seem quite limited, and it's hard to see how it would fit in with the pricing structure.

Calling the 60 CU part the RX 7800 would make sense.

A 64 CU part seems unlikely, Angstronomics reported the top Navi32 GPU to have 60 CUs.

Well, I'd say this GPU makes a lot of sense:

It's nice that it's a Navi31 design, but basically cut down. I guess they thought Navi32 just wouldn't offer enough of an improvement vs the last gen.

It should be ahead of the RTX 4070 in performance (therefore RTX 3080 also). And it has a reasonable amount of VRAM.

The RTX 4070 TI is going to look pretty expensive compared to the RX 7900 (that's what I'm calling it).

I guess they're nearly done with RDNA3 releases now.

I imagine some gamers will still want a Navi32 successor to the RX 6700 XT as well.

The spec of the RX 7900 looks fairly similar to the RX 7900 XT, but the memory bandwidth is lower:

The performance should be pretty decent in theory.

I'd expect the RX 7900 to be 5-10% slower in raster than the RTX 4070 TI (which is around 20% faster than the RTX 4070).
I guess the thing we don't know yet, is will cut down Navi31 GPUs be mass market products, or quite limited in yields? Maybe the 80 CU dies will be easier /simpler to mass produce?

The main market for this GPU will be people not impressed with the RTX 4070's performance, who might like to have more VRAM.

I think it's very likely that the price of the RTX 4070 will come down.

So, what he says about the top RDNA3 GPUs is true, there's about 2x the number of transistors (compared to RDNA2), but the raster GPU performance isn't anything like 2x as fast. I personally found RDNA gen 1 unimpressive, but it doesn't get a mention. At the time there was lots of talk of 'Big Navi' eventually arriving - But AMD basically admitted there were scaling issues with the first generation - It's remains a problem in 2023...

The same thing is true for Nvidia's top Ampere and 'Ampere Next' GPUs, more than a doubling of transistors doesn't give you anything like 2x the performance (GA102 - 28.3 billion transistors vs AD102 - 76.3 billion transistors), so he is starting off from a false premise - it just isn't that simple. I think he's being a bit histrionic, considering that prices are going to come down further for RDNA3 GPUs, probably from September onwards.

Also, Nvidia already had a significant advantage with the RTX 3090 and 3090 TI in performance when these cards released - the RX 7900 XT beats or matches both.

It's quite possible that Navi32 GPUs will look unimpressive, relative to Navi21 - But still a reasonable upgrade compared to Navi22 (cards like the RX 6700 XT).
AMD's main with their new GPUs problem is scaling, contrary to what lots of people have been banging on about (clock speed).

You can see this just by looking at the RDNA2 consoles that struggle to reach 30 FPS at 4K in some titles (The Series X GPU has 52 Compute Units). They don't have enough Compute Units, I think you'd need at least twice as many to deliver a steady 60 frames per second at reasonable level of image quality, and this should apply for ray tracing also. 120 CUs seems like it would be a good target for RDNA4.

So people need to look at the functional units of GPUs, not the transistor count - because the architecture is different and is designed to do more tasks, like compute, AI and ray tracing. I believe the RDNA3 CUs are fairly well optimised - the issue is that there just isn't enough of them - they need to make significant power improvements with RDNA4, to allow for much higher CU counts.

AMD is not going to release a GPU which requires a 800 or 1000 watt power supply, presumably because it just isn't worth it (people buy the high end cards they sell anyway) and it would almost certainly require an 'exotic' cooling solution. Undoubtedly, they'd be much more difficult to produce also, at least with the current RDNA3 5nm fabrication process.

A final point on ray tracing in 2023:

watch-dogs-legion-rt-3840-2160.png


There's really just one card that does 'well' in ray tracing and it (still) costs >£1,500, and is recommended with a 850 watt power supply.

But you can see that a linearly scaled up RDNA3 (or more likely, RDNA4) GPU ought to be able to match this level, and do it at a cheaper price point - but until that happens, we're a long way from RT becoming a standardised feature in PC games (that game developers put time and effort into optimising).

It looks like the RX 7900 GRE is going to be a limited release, not for the PC building market sadly,..


No wonder it has a silly name, rather than just being the 'RX 7900'.

The only good thing to say about this release really, is that the 260w tdp sounds quite power efficient.

So that pretty much just leaves Navi32 GPUs to launch in September. I think the main selling point of these will be FSR3, which will likely only work on RDNA3 cards.

AMD hasn't said anything about FSR3 or frame generation support on consoles, which have RDNA2 GPUs, so I doubt it's possible on existing consoles.

If new consoles or refreshes are released with RDNA3 or maybe RDNA4 GPUs, I imagine FSR3 /similar software will be enabled on future console games.

Ampere lacks proper hardware support for frame generation, so Nvidia decided not to add driver support for it on Ampere. Similarly, RDNA2 has no hardware support for frame gen. so I doubt AMD will add FSR3 driver support. If it's possible, it will be something that gets added later, but I'm doubtful it would function well.

AMD ofc won't tell people in advance that FSR3 is unlikely to be supported on older GPUs, because they really need to sell off the remaining series of RDNA2 GPUs.

Baldur's Gate 3 is getting support for FSR2 in September, it's interesting to see no mention of FSR3 - Presumably the developers would rather support FSR2 to make there's a widely supported upscaling tech available shortly after release. Or, maybe FSR3 is still too new and developers aren't sure how to implement it yet.

I expect that AMD has already done a lot of work on designing RDNA4, as I think they are wrapping up the RDNA3 series now. If RDNA4 GPUs are going into future consoles, the focus on the new series will be even greater.

I think one of the things I dislike about upscaling and RT is the necessity to spend even more time tweaking game settings, no longer can you just set resolution and graphics preset (e.g Ultra). I suppose it's less of an issue on 1080p monitors.

If you are going to spend money (to play games), I'd spend it on the GPU first, in most games that will help you to achieve the highest min. framerate.

The higher the resolution, the more you will be GPU bottlenecked.

Ray tracing can be CPU intensive also, but for that you may want an expensive Nvidia GPU anyway, like the 4080/4090.

Personally, wouldn't spend a lot on a CPU now, as Zen 5 CPUs will be out next year, even the 6 core model will probably end up 20% faster.

An 8 core Vcache might be worth it if you can get a cheaper one 2nd hand.

You could wait to see if pre built systems with RX 7900 GRE graphics cards installed are affordable, I imagine AMD will want to sell these mostly with Zen 4 CPUs.

Bestsellers:
1. XFX Radeon RX 6700 XT Speedster SWFT 309 Core Gaming
2. XFX Radeon RX 6950 XT Speedster MERC 319 Black Gaming
3. MSI GeForce RTX 3060 Ventus 2X OC

[/SPOILER]
£560 inc VAT seems like an OK price for the RX6950XT.

EDIT - nvm, that's from a dodgy amazon seller by the looks of things.

FSR3 eta s0n


I think they need to find a way to implement this frame gen tech without requiring support from each game developer /title.

Ideally, just get it working with all FSR2 games.
