In addition to its grand Ryzen 7000 “Zen 4” CPU launch, AMD has additionally given us a primary take a look at their next-gen Radeon RX 7000 “RDNA 3” GPUs.

AMD Shows Off Next-Gen Radeon RX 7000 Series With RDNA 3 GPU Architecture

The teaser proven by AMD provides us a take a look at the graphics card which options the RDNA 3 GPU core. This might be one of many flagship designs of the lineup and it additionally appears to be barely thicker than the present playing cards such because the RX 6950 XT. The shroud seems to be similar to the reference design utilized by present playing cards and we will additionally see a touch of RGB illumination on the entrance of the cardboard.

AMD confirmed that its RDNA 3 GPUs can be coming later this yr with an enormous efficiency uplift. The firm’s Senior Vice President of Engineering, Radeon Technologies Group, David Wang, stated that the next-gen GPUs for Radeon RX 7000 sequence will provide over 50% efficiency per watt uplift vs the present RDNA 2 GPUs. Some of the important thing options of the RDNA 3 GPUs highlighted by AMD will embody:

  • 5nm Process Node
  • Advanced Chiplet Packaging
  • Rearchitected Compute Unit
  • Optimized Graphics Pipeline
  • Next-Gen AMD Infinity Cache
  • >50% Perf/Watt vs RDNA 2

In the data printed by AMD, the corporate highlighted a couple of key options of its RDNA 3 GPUs that may energy the following technology of Radeon RX graphics playing cards. The RDNA 3 GPU can be primarily based on a 5nm course of node and make the most of a complicated chiplet packaging that delivers elevated efficiency per watt. Furthermore, the GPU will home a spread of latest applied sciences similar to a model new and rearchitected Compute Unit, an optimized graphics pipeline, and the next-gen of Infinity Cache.

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 heard that AMD will drop CU (Compute Units) in favor of WGP (Work Group Processors) on its next-gen RDNA 3 GPUs. Each WGP will home twin CU (Compute Units) however with twice the SIMD32 clusters versus simply 2 on every CU inside RDNA 2. Rumors are that AMD has the choice to pick out 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

According to 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. This 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 alleged to measure 308mm2 and can come packaged on TSMC’s 5nm course of node.

The Navi 31 GPU can even carry 6 MCD’s which can characteristic 16 MB Infinity Cache per die and are additionally prone to carry the 64-bit (32-bit x 2) reminiscence controllers that may present the chip with a 384-bit bus interface. While 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 answer within the works which was identified not too long ago and that might double the Infinity Cache with 32 MB (16 MB 0-hi + 16 MB 1-hi) capacities for a complete of 192 MB of cache. This is a 50% enhance 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 can be fabricated on TSMC’s 6nm course of node and measure 37.5mm2 every.

The outlet reviews that there was a good increased 288 MB (16 MB 0-Hi + 16 MB 1-Hi + 16 MB 2-Hi) MCD bundle deliberate however that was scrapped as a consequence of cost-benefit causes. There are additionally talks of a cut-down variant of the Navi 31 GPU which can characteristic 42 WGPs or 10,752 cores and 5 MCDs for 80MB Infinity Cache throughout a 320-bit bus interface.

Now, that is going to lead to increased 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 possibility 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 presently in use.

AMD Navi 32 “Wheat Nas” GPU Configuration

The AMD Navi 32 GPU codenamed “Wheat Nas” can be one of many two MCM GPUs featured within the RDNA 3 lineup. The GPU will characteristic a single GCD (Graphics Compute Dies) and 4 MCDs (Multi-Cache Die). The GPU or GCD is alleged to measure 200mm2 whereas every MCD will retain the identical measurement at 37.5mm2.

  • AMD Navi 32: 7680 Cores, 256-bit Bus, 64 MB Infinity Cache, 200mm2 GPU Die @5nm
  • AMD Navi 22: 2560 Cores, 192-bit Bus, 96 MB Infinity Cache, 335mm2 GPU Die @7nm

The GCD can be outfitted with 3 Shader Engines and every Shader Engine has 6 Shader Arrays (18 in whole). The GPU will characteristic a complete of 30 WGP or 60 Compute Units for a complete of 7680 cores. This rounds as much as >50% extra cores than the Navi 31 flagship.

Each MCD also needs to characteristic 2 reminiscence join hyperlinks (32-bit). That’s a complete of 8 32-bit reminiscence controllers for a 256-bit bus interface. Each MCD will retain the 16 MB 0-Hi capability however there doesn’t appear to be any 1-Hi variant which implies that the chip may have simply 64 MB most configs. That Navi 32 GPU is alleged to launch in 2023 and would be the highest chip for cell and mid-tier chip for desktops. The GPU can be first rolled out to the cell phase and is likely to be introduced at CES 2023 which makes ideally suited sense since we may have Phoenix Range and Dragon Range laptops with Zen 4 cores prepared by then.

AMD Navi 32 “Hotpink Bonefish” GPU Configuration

The AMD Navi 33 GPU codenamed “Hotpink Bonefish” will begin the monolithic phase throughout the RDNA 3 household. The GPU will characteristic a single die. The die is similar to the flagship Navi 21 GPU and is anticipated to make the most of a 6nm course of node for fabrication with a die measurement of 203mm2.

  • AMD Navi 33: 4096 Cores, 128-bit Bus, 32 MB Infinity Cache, 335mm2 GPU Die @6nm
  • AMD Navi 23: 2048 Cores, 128-bit Bus, 32 MB Infinity Cache, 237mm2 GPU Die @7nm

The Navi 33 GCD is anticipated to characteristic 2 Shader Engines and every Shader Engine has 2 Shader Arrays (2 per SE / 4 in whole). This rounds as much as 16 WGP’s or 32 Compute Units for a complete of 4096 cores which is increased than the Radeon RX 6800 “Navi 21 XL” GPU. The GPU will come packaged with 32 MB of Infinity Cache, the identical quantity because the Navi 23 GPU, and throughout a 128-bit huge bus. Just just like the Navi 32 GPUs, the Navi 33 chips can be centered first on the cell lineup with early graphics efficiency placing them forward of the Intel Arc Alchemist lineup at lower than half the price & whereas pulling much less energy.

The AMD Radeon RX 7000 “RDNA 3” GPU lineup primarily based on the Nav 3x GPUs is anticipated to launch later this yr with reviews pitting the flagship Navi 31 launch first adopted by Navi 32 and Navi 33 GPUs.
