AMD Subsequent-Gen RDNA 3 Navi 31 & Navi 33 GPUs Listed In ROCm OpenGPU Platform

AMD has formally confirmed two of its next-generation RDNA 3 GPUs, the Navi 31 and Navi 33, which have been added to the help listing of the ROCm GPUOpen platform. Other than these, ROCm itemizing additionally confirms Rembrandt and Van Gogh APUs.

AMD RDNA 3 Navi 31 & Navi 33 GPUs Confirmed In Newest ROCm OpenGPU Platform Assist Record

Noticed by Komachi, the newest developer instruments replace for AMD’s ROCm OpenGL platform lists down the next-generation RDNA 3 primarily based Navi 31 and Navi 33 GPUs. There have been latest stories which alleged that AMD will probably be taping out its next-generation GPUs later this yr & this might probably be preliminary help for builders.

AMD RDNA 3 Navi 31 GPUs For Radeon RX 7800/7900 Sequence

The AMD Navi 31 GPU, the flagship RDNA 3 chip, would energy the next-gen 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.

The Navi 31 GPU configuration proven right here options two GCD’s (Graphics Core Die) and a single MCD (Multi-Cache Die). Every GCD has 3 Shader Engines (6 in complete) and every Shader Engine has 2 Shader Arrays (2 per SE / 6 per GCD / 12 in complete). Every Shader Array consists of 5 WGPs (10 per SE / 30 per GCD / 60 in complete) and every WGP options 8 SIMD32 models with 32 ALUs (40 SIMD32 per SA / 80 per SE / 240 per GCD / 480 in complete). These SIMD32 models mix to make up 7,680 cores per GCD and 15,360 cores in complete.

The Navi 31 (RDNA 3) MCD will probably be linked to the twin GCD’s through a next-generation Infinity Material interconnect and have 256-512 MB of Infinity Cache. Every GPU must also characteristic 4 reminiscence join hyperlinks (32-bit). That is a complete of 8 32-bit reminiscence controllers for a 256-bit bus interface.

There have been a number of rumors stating that the upcoming RDNA 3 GPUs are going to outperform no matter NVIDIA has to supply when it comes to rasterization efficiency. It seems to be like AMD will take the lead by providing the primary MCM-powered GPUs beneath its Radeon RX graphics card lineup. However on the similar time, NVIDIA is anticipated to shortly transition to its MCM GPU lineup which can provide over 3x efficiency increase over Ampere GPUs.

AMD RDNA 3 Navi 33 GPUs For Radeon RX 7600 Sequence

The AMD Navi 33 GPU will begin the monolithic phase inside 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.

The Navi 33 GCD has 2 Shader Engines and every Shader Engine has 2 Shader Arrays (2 per SE / 4 in complete). Every Shader Array consists of 5 WGPs (10 per SE / 20 complete) and every WGP options 8 SIMD32 models with 32 ALUs (40 SIMD32 per SA / 80 per SE / 160 complete). These SIMD32 models mix to make up 5120 cores which is similar core depend because the RX 6900 XT (Navi 21 XTX GPU).

The Navi 33 (RDNA 3) is anticipated to hold 256 MB of Infinity Cache. Every GPU must also characteristic 2 reminiscence join hyperlinks (32-bit). That is a complete of 4 32-bit reminiscence controllers for a 128-bit bus interface. This is able to convey the efficiency of the AMD Radeon RX 7600 sequence above the RX 6800 and RX 6900 sequence at a TDP of round 200W.

The AMD RDNA 3 ‘Navi 3X’ GPU-powered Radeon RX graphics card lineup is anticipated to supply as much as 3x efficiency enchancment over present RDNA 2 choices. It could mark a significant leap ahead for graphics evolution and now that AMD is already onboard with next-gen applied sciences reminiscent of FSR and Raytracing, count on a really heated next-gen competitors between the crimson and inexperienced groups.
