AMD shall be unveiling its RDNA 3 GPU-powered Radeon RX 7000 graphics playing cards in a couple of weeks and now we have received some new data on one of many flagship fashions, the Radeon RX 7900 XT.

AMD Radeon RX 7900 XT To Function RDNA 3 “Navi 31” GPU Core & 20 GB GDDR6 VRAM

The AMD RDNA 3 GPU lineup will kick off first with high-end choices primarily based on the Navi 31 MCM chip. The chip shall be featured in enthusiast-class Radeon RX 7000 graphics playing cards together with the RX 7900 XT which now we have acquired new details about from our sources. As per the small print, the AMD Radeon RX 7900 XT graphics card will not be the highest mannequin however it should characteristic 20 GB of GDDR6 VRAM.

Our source studies that AMD’s Radeon RX 7000 “RDNA 3” GPUs might exceed expectations & whereas there are conflicting rumors from Chinese language sources, it appears to be like like the top consequence is likely to be a much better product than anticipated. We have now additionally come to know that the AMD Radeon RX 7900 XT initially featured 24 GB of reminiscence capability earlier than being downgraded to twenty GB. The Full-Fats 24 GB & High Navi 31 bin shall be geared toward NVIDIA’s full-Fats Ada die (the RTX 4090 Ti). AMD appears very assured that with 20 GB and a barely cut-down MCM chip, they’ll sit in a snug place towards the RTX 4090 and should even outperform it in pure rasterization efficiency whereas bringing a giant soar in RT efficiency versus the prevailing RDNA 2 GPUs.

With the Radeon RX 7900 XT using 20 GB of reminiscence, it will point out that the rumors concerning a higher-end SKU appear to be true. AMD has already began utilizing the *950 XT conference in its final RDNA 2 technology of GPUs so an RX 7950 XT is definitely occurring. Angstronomics additionally reported on comparable particulars some time again of their juicy article over right here which it is best to positively try.

AMD Navi 31 “Plum Bonito” GPU Configuration

The AMD Navi 31 GPU, the flagship RDNA 3 chip, would energy the next-gen fanatic playing cards such because the Radeon RX 7900 XT graphics card. We have now heard that AMD will drop CU (Compute Models) in favor of WGP (Work Group Processors) on its next-gen RDNA 3 GPUs. Every WGP will home twin CU (Compute Models) however with twice the SIMD32 clusters versus simply 2 on every CU inside RDNA 2. Rumors are that AMD has the choice to pick between Samsung and TSMC for the 6nm die.

  • AMD Navi 31: 12288 Cores, 384-bit Bus, 192 MB Infinity Cache, 308mm2 GPU Die @5nm
  • AMD Navi 21: 5120 Cores, 384-bit Bus, 128 MB Infinity Cache, 520mm2 GPU Die @7nm

In line with the newest data, the AMD Navi 31 GPU with RDNA 3 structure is anticipated to supply a single GCD with 48 WGPs, 12 SAs, and 6 SEs. It will give out a complete of 12,288 SPs or stream processors. This is a rise of two.4x in cores in comparison with the 5120 SPs featured on the Navi 21 GPU. The GPU or the Navi 31 GCD is claimed to measure 308mm2 and can come packaged on TSMC’s 5nm course of node.

AMD Radeon RX 7900 XT

The Navi 31 GPU can even carry 6 MCD’s which can characteristic 16 MB Infinity Cache per die and are additionally more likely to carry the 64-bit (32-bit x 2) reminiscence controllers that can present the chip with a 384-bit bus interface. Whereas this equals 96 MB of Infinity Cache which is decrease than the 128 MB featured on the present Navi 21 GPUs, there’s additionally a 3D-Stacked resolution within the works which was identified not too long ago and that may double the Infinity Cache with 32 MB (16 MB 0-hi + 16 MB 1-hi) capacities for a complete of 192 MB of cache. It is a 50% improve versus the present Navi 21 design and it additionally makes Navi 31 the primary GPU with each, chiplet and 3D stacked designs. These chiplets or MCD’s shall be fabricated on TSMC’s 6nm course of node and measure 37.5mm2 every.

Now, that is going to end in the next energy draw and AMD appears to have confirmed this a lot that their next-generation graphics card lineup will characteristic increased energy consumption however they’ll nonetheless be a extra environment friendly choice than what NVIDIA has to supply. The AMD Radeon RX 6950 XT already has a TBP of 335W so for a >2x efficiency acquire. The playing cards are anticipated to retain their twin 8-pin plug enter for energy and have an up to date triple-fan cooling design which is barely taller than the one at present in use.
