    Phoronix: AMD RDNA3 GPUs Can Have A Lot More Vector Registers Than RDNA2

    A code commit that was merged to LLVM's AMDGPU shader compiler back-end on Friday afternoon confirms that GFX11/RDNA3 GPUs can have a lot more vector registers than prior GFX10 (RDNA / RDNA2) GPUs...

    Probably means a 50% price increase, because apparently if you're not spending at least $250, you might as well buy something used.

      Time will tell - with nVidia just announcing the debacle that is the 4090/4080. I'm thinking of going AMD on my next build, I'm currently Intel/nVidia now, at least my main PC. This laptop is AMD/nVidia, and I'm pretty impressed with it. Let's hope AMD doesn't decide it can start running away with prices...

        You mean in terms of size/power/MSRP? Yeah, pretty tone-deaf, on all accounts. Let's hope they release a power/price-"optimized" variant, in coming months.

        The power & pricing of the 4000-series launch lineup is a real shame, because it does have some cool features.

        Although it's a CPU and not a GPU, AMD announced (a few weeks ago) its 7950X would launch at $100 cheaper than its 5950X did. I think that's pretty impressive.

          I still think the RX 6400 / 6500XT was designed to scale down well to lower prices. I'm pretty sure AMD would even make money on them, if they drop below $100. Intel's A380 has a die on the same process node that's 50% bigger and it has 50% more DRAM. If Intel & its board partners can at least break even at $140, then there has got to be some flexibility left in the Navi 24 price structure.

          I realize your $250 price threshold already excludes Navi 24, but if we take it as a sign of where AMD is headed with RDNA 3 (being the last RDNA 2 chip they launched), then it could be somewhat promising.

            if AMD doesn't get too greedy (Nvidia's pricing reached the insulting level long ago), they can take a lot of market share this generation. And from what I saw from the rumors, they have decent offerings in the pipeline which are optimized for performance per area per watt. Even though 5nm is a more costly process, that hints to a cost advantage against Nvidia that could (and should!) trickle down to us consumers eventually.

              Yes sir, quite true - I didn't really mention it in my last post because I didn't want to sound snobbish - my current rig is an i9-10980xe with an rtx 3090 (non-Ti) and 256GB of system RAM. I run Windows on that machine, and run a very, very heavily modded Skyrim (among other workloads). 24GB of VRAM might seem excessive, but I've seen it use as much as 92% of that memory!! I've thought about pursuing AMD's professional cards, that have 32GB of VRAM on them. Gaming isn't all I do, I also run [email protected] and [email protected] as well.

              Heck, the only reason I have a system that nice is all the overtime I worked in 2020-2021. I dropped a metric ton of cash on that thing. Enough to buy a quality used car. In today's economy, that would be highly unwise to do for sure. And I'm sure the wife wouldn't be happy about it either.

              Been a long time lurker on this forum, and decided it was about time to start getting involved.

                  the sources i know speak of a very small increase of the price compared to the old 6000 models in the same vram size more like 50€... not 50%...

                  https://geizhals.de/?cat=gra16_512&x...2+-+RX+6950+XT

                  the 6950XT is now 900€ the 7000 card with 16gb vram will be 950€...

                  https://geizhals.de/?cat=gra16_512&x...2+-+RX+6650+XT

                  the 6650xt is 360€ the 700 card with 8gb vram will be 410€

                  https://geizhals.de/?cat=gra16_512&x...2+-+RX+6750+XT

                  the 6750xt is now 490€ the 7000 card with 12gb vram is 540€ ...

                  the only card who is more pricy is the 24GB vram model with 3D stagged cache will be something like 1400€...

                  but the RTX 4090 will be 1900€... compared to this the amd cards will be cheap...

                  and the 7000 cards will have FSR3(similar to DLSS) in hardware FMA/Matrix AI cores what will make it 8% faster compared to FSR2.1
