AMD RDNA 3 Navi 32 GPU For Radeon RX 7700 XT & Navi 33 GPU For Radeon RX 7600 XT Graphics Playing cards Detailed

After the Navi 31 GPU die, the RDNA 3 primarily based Navi 32 GPU for the AMD Radeon RX 7700 XT & Navi 33 GPU for Radeon RX 7600 XT graphics playing cards have been detailed too. The main points as soon as once more are reported and visualized as GPU block diagrams by Olrak over at Twitter.

AMD RDNA 3 Navi 32 & Navi 33 GPUs Detailed – Would Energy Subsequent-Gen Radeon RX 7700 XT & RX 7600 XT Graphics Playing cards

The AMD RDNA 3 lineup will encompass each monolithic and MCM GPUs that will energy the next-gen Radeon RX 7000 sequence graphics playing cards. Now we have been listening to studies that the Navi 3X graphics chips might be taping out quickly so it is too early to inform if the data is used to visualise these dies is dependable or not however they do come from sources who’ve been fairly correct with their leaks so it’s sensible to learn these particulars with a pinch of salt.

AMD RDNA 3 Navi 32 GPUs For Radeon RX 7700 Collection

The AMD Navi 32 GPU might be one of many two MCM GPUs featured within the RDNA 3 lineup. The GPU will function two GCD’s (Graphics Compute Dies) and a singular MCD (Multi-Cache Die). The die is similar to the flagship Navi 31 GPU however has one much less Shader Engine throughout every die. The AMD Navi 32 GCD is anticipated to make the most of TSMC’s 5nm course of node whereas the MCD might be primarily based on a 6nm course of node. Rumors are that AMD has the choice to pick between Samsung and TSMC for the 6nm die.

Every GCD has 2 Shader Engines (4 in whole) and every Shader Engine has 2 Shader Arrays (2 per SE / 4 per GCD / 8 in whole). Every Shader Array consists of 5 WGPs (10 per SE / 20 per GCD / 40 in whole) and every WGP options 8 SIMD32 models with 32 ALUs (40 SIMD32 per SA / 80 per SE / 160 per GCD / 320 in whole). These SIMD32 models mix to make up 5120 cores per GCD and 10,240 cores in whole.

The Navi 32 (RDNA 3) MCD might be linked to the twin GCD’s by way of a next-generation Infinity Cloth interconnect and have 384 MB of Infinity Cache. Every GPU also needs to function 3 reminiscence join hyperlinks (32-bit). That is a complete of 6 32-bit reminiscence controllers for a 192-bit bus interface.

This could convey the efficiency of the AMD Radeon RX 7700 sequence above the RX 6800 and RX 6900 sequence, providing one huge leap in graphics horsepower in video games. This could additionally pump up the facility numbers because the RX 6700 XT is at the moment rated at 230W however that would go as much as 270-300W.

AMD RDNA 3 Navi 33 GPUs For Radeon RX 7600 Collection

The AMD Navi 33 GPU will begin the monolithic phase inside the RDNA 3 household. The GPU will function 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 whole). Every Shader Array consists of 5 WGPs (10 per SE / 20 whole) and every WGP options 8 SIMD32 models with 32 ALUs (40 SIMD32 per SA / 80 per SE / 160 whole). These SIMD32 models mix to make up 5120 cores which is identical 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 also needs to function 2 reminiscence join hyperlinks (32-bit). That is a complete of 4 32-bit reminiscence controllers for a 128-bit bus interface. This could convey the efficiency of the AMD Radeon RX 7600 sequence above the RX 6800 and RX 6900 sequence at a TDP of round 200W.

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

The AMD Navi 31 GPU, the flagship RDNA 3 chip, would energy the next-gen Radeon RX 7900 XT graphics card. Now we have heard that AMD will drop CU (Compute Items) 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 whole) and every Shader Engine has 2 Shader Arrays (2 per SE / 6 per GCD / 12 in whole). Every Shader Array consists of 5 WGPs (10 per SE / 30 per GCD / 60 in whole) and every WGP options 8 SIMD32 models with 32 ALUs (40 SIMD32 per SA / 80 per SE / 240 per GCD / 480 in whole). These SIMD32 models mix to make up 7,680 cores per GCD and 15,360 cores in whole.

The Navi 31 (RDNA 3) MCD might be linked to the twin GCD’s by way of a next-generation Infinity Cloth interconnect and have 256-512 MB of Infinity Cache. Every GPU also needs to function 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 by way of rasterization efficiency. It seems to be like AMD will take the lead by providing the primary MCM-powered GPUs underneath its Radeon RX graphics card lineup. However on the similar time, NVIDIA is anticipated to rapidly transition to its MCM GPU lineup which can provide over 3x efficiency enhance over Ampere GPUs. Following is the anticipated efficiency improve:
