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

It looks like you can fix the minimum clock rate and set the voltage within AMD's software:



The RX 7900 XT's hotspot temp. seems to be quite high with these settings though (close to 90).

I hope someone can get their hands on a Radeon PRO W7800 card and do a review, showing performance in games.

Would be interesting to see if it can get close to an RTX 4070 TI.

Don't they have totally different drivers.

The RX7600S which uses a cut down 6NM die compared to a full TSMC 4N 5NM AD107:

At similar power the RX7600S has similar rasterised performance but OFC worse RT performance. Surprised considering the RTX4060 mobile is on a much better process node.

Apparently the desktop RTX4060 might use the AD107(the RTX4060TI might use the AD106).

Guess that additional RT performance¹ and those tensor sensors² do take to a lot of space.

Navi 33 seems to be designed to be extra cheap to produce. Nothing wrong with as long as that is reflected in its price.

But for ¹, I actually believe that having most of that done at the shader level like AMD do makes more sense. Longer term, I really expect some fixed function units but not just for rays but also since of the setup as currently RT puts quiet a large load on the CPU.

For ²? Well, don't really think tensors are required for consumer loads but Nvidia have marketed then to death now so we shall see.

Rather than buying into Nvidia's marketing, I wish PCMR would start complaining that - like with Intel iGPUs on CPUs - they don't want to pay for things they don't use like they did with the old "I'd rather have more cores". Of course, that would force Nvidia to use separate chips for games and professional work.

If you read some of the bumpf about RDNA2 and the new consoles,it was about how AMD added RT to the existing RDNA1 designs with relatively few extra transistors. This definitely has some advantages for AMD for IGPs used in their APUs,and the ARM based SOCs which Samsung are designing too. The RDNA2 and RDNA3 IGPs look fantastic too:

So it does seem RDNA3 is performing well,and it makes me wonder when Navi 31 performance is being negatively affected by the chiplet design. I wonder how it would have performed as a monolithic design made on the same TSCM 4N 5NM Nvidia is using??

It would have been cool if instead of sticking RT cores on GPUs Nvidia stuck them on an add-on card like physx back in the day. They'd be able to dedicate the entire GPU to raster and dedicate even more RT cores to the add on card

I'm thinking of buying a RX 7900 XT at some point, if I can buy a used or new one for ~£650.

I could wait for a RX 7800 tier GPU (Navi31) but I'm fairly sure these will cost £600 or more...

 

[g67575]

oof.

They're recommending a RTX 3090 /rx 6950 XT to play this game at 4K 60 FPS:

For some reason, a Ryzen 7700X is deemed insufficient to play smoothly at 4K Ultra

Those were the GPUs for 4k 60 , seems normal.

Dunno why people think you can do with less

 

[g67575]

Techpowerup's rumoured spec is up for the RX 7800 XT, which will apparently be based on the Navi32 GPU die:

AMD Radeon RX 7800 XT Specs

AMD Navi 32, 2430 MHz, 3840 Cores, 240 TMUs, 96 ROPs, 16384 MB GDDR6, 2438 MHz, 256 bit

www.techpowerup.com

It looks okay, seems like it will perform similarly to the top Navi21 GPUs.

And best the RTX 3080 and RTX 4070.

I think it would be a shame if there's no more consumer Navi31 GPUs released...

 

[g67575]

Those were the GPUs for 4k 60 , seems normal.

Yeah, true. The Last of Us requirements are even steeper, the heaviest I've seen in any PC game:

But a less silly CPU recommendation though.

 

[JediFragger]

Navi31

He means 21.

Am expecting 6900XT-ish myself.

 

[SpudMaster]

But a less silly CPU recommendation though.

It also recommends an RX 5800XT....

 

[CAT-THE-FIFTH]

It appears the full Navi 33 is being called the RX7600 non-XT and will be an 8GB VRAM card:

RX 7600 Launch Leak, Intel’s Apocalyptic Earnings, Zen 5 Recap, AMD Strix vs MTL | April Loose Ends

www.youtube.com

So I wonder if the RX7600XT might be reserved for a model with more VRAM? I hope this is under $300/£300,because this looks more like an overclocked RX6650 8GB with some RDNA3 improvements,so probably is no better than an RX6700 10GB/RX6700XT 12GB but with less VRAM.

 

[g67575]

He means 21.

This.

 

[g67575]

Unfortunately, it looks like the Navi31 yields (RX 7900 XT and XTX) have sucked so far, based on stock levels I've checked on a couple of sites.

Which likely means AMD has invested a lot, but not yet seen much return on their investment for RDNA3.

Especially compared to the RTX 4070, which has 400-500 items in stock for some models (e.g. Palit).

Might be worth waiting for though.

Edit - One site I checked has a couple hundred 7900 XTs in stock for some Sapphire models, so maybe it's not so bad.

Could be that some of the N31 dies are being reserved for workstation GPUs (due to become available soon) to maximize the profits.

I'd put money on the RX 7800 XT having better yields, assuming it's a Navi32 (5nm) based card.

 

[TrojanWhore]

That rumoured n32 7800xt seems to land exactly where I thought it should, just need to see how that translates to pricing.

Still leaves room for another card in between though.... 7800xtx or 7900 (non XT).... something like 64/72 CU and 16GB(256bit)/18GB(288)/20GB(320), depending on how that affects the IO die config.
Regarding yields, I guess it depends whether the defect rate is higher on a fully enabled n32, or a heavily shaved n31

 

[g67575]

It would almost certainly be a 70 Compute Unit model based on Navi31 (just like the W7800), but because the yields don't look great, I'm not sure if AMD will bother.

Maybe in 6-9 months?

It doesn't bode well for RDNA4 (likely 100 CUs or more), if AMD + TSMC are struggling to produce GPUs with 70 CUs on 5nm.

 

[TrojanWhore]

Ah, I'm not familiar with the workstation lineup - was just thinking in logically divisible steps from full die.
Yeah, if they're having trouble getting a 70cu sku reliably, that really could spell bad times...
