AMD is difficult on work to prepared their next-generation RDNA 3 lineup and it seems to be just like the flagship Navi 31 GPU for the upcoming Radeon RX lineup has been taped out at the moment. A tweet from leaker, Greymon55, means that AMD has taped out its flagship graphics chip for 2022.
AMD RDNA 3 Structure Powered Navi 31 GPU For Subsequent-Gen Flagship Radeon RX Graphics Card Reportedly Taped Out
Again in August, the identical leaker reported that AMD will likely be taping out its flagship RDNA 3 GPU, the Navi 31, in two months and it seems to be like at the moment is the day because the leaker has now tweeted out that the flagship is prepared! Now taping out doesn’t suggest that we’re near launch nevertheless it is without doubt one of the many key milestones in chip growth. Will probably be someday earlier than the chip achieves energy on by AMD themselves after which we’re going to begin seeing the primary engineering samples start to roll out to key companions.
Subsequent technology flagship graphics card has been taped out.

As for the launch, the RDNA 3 based mostly AMD Radeon RX 7000 collection is predicted throughout the second half of 2022. So we’re nonetheless an excellent whereas away from launch nevertheless it’s good to listen to such growth mile-stones from the back-channel.
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’ve got 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 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 will likely 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 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 predicted to rapidly transition to its MCM GPU lineup which can provide over 3x efficiency increase over Ampere GPUs.
