@Greymon55 just broke the news on Twitter: AMD is working hard to launch the next generation of RDNA 3 new products, and the flagship model Navi 31 GPU has begun to stream today.In fact, as early as August, the same whistleblower revealed that AMD will come up with RNDA 3 (Navi 31) GPU within two months. It now appears that the company should have completed the preliminary preparations.
Of course, this does not mean that we will soon be able to buy new Radeon RX 7000 series graphics cards. As an important milestone,AMDThe main partners will first carry out the research and development of engineering samples, and then strive to bring them to the market in the second half of 2022.
The flagship RDNA 3 “Navi 31” GPU will be used by the Radeon RX 7900 XT graphics card, and there are rumors that AMD will abandon the “computing unit” (CU)-based representation in this generation and instead adopt the “working group” ( WGP) processing unit.
The GPU configuration of Navi 31 includes two parts “Graphics Core Chip” (GCD) and “Multi-Cache Chip” (MCD).
Each GCD has 3 shader engines (6 in total), and each Shader Engine is subdivided into two shader arrays (2 per SE / 6 per GCD / 12 in total).
Then each Shader Array is composed of 5 groups of WGP (10 per SE / 30 per GCD / total 60), and each group of WGP has 8 SIMD32 units / 32 ALUs (40 per SA / 80 per SE / 240 per GCD / 480 SIMD32 units in total).
All these SIMD32 units are combined to form 7,680 cores per GCD / 15,360 total cores in total.
In addition, the RNDA 3 “Navi 31” MCD will use the next-generation Infinity Fabric to connect to the dual GCD, supplemented by the 256-512 MB “Infinity Cache” (Infinity Cache).
Each GPU also has 4 @ 32-bit memory connect links, for a total of 8 @ 32-bit (256-bit total) bus interfaces.
Finally, it is rumored that the upcoming RDNA 3 GPU with multi-chip design (MCM) will surpass any product provided by NVIDIA (three times the Ampere GPU) in terms of rasterization performance.
If this is the case, then NVIDIA may quickly turn to follow-up MCM GPU design under the pressure of huge market competition.
