The second half of 2022 is going to be full of exciting new launches in both the CPU and GPU markets. We’re expecting the launch of AMD’s Ryzen 7000 and 4th Gen Epyc Genoa processors based on the 5nm Zen 4 core architecture sometime in August or September. This will be accompanied by the unveiling of the Navi 33-based Radeon RX 7700 XT around the same time, followed by the Radeon RX 7900 XT (Navi 31) one or two months later.
According to sources, the Radeon RX 7000 GPUs (Navi 31/32/33) are already being internally tested and a September launch is highly probably. The Radeon RX 7700 XT leveraging the 6nm Navi 33 die will be the first to launch, followed by the RX 7900 XT (Navi 31) and finally, the RX 7800 XT (Navi 32). The Radeon RX 7900 XT will be the highlight with a total of up to seven dies. Two of these will be the GCDs (Graphics Compute Dies), one I/O die (or the active bridge interconnect), and four memory/cache controller dies paired with GDDR6 memory modules. The GCDs will be fabbed on TSMC’s 5nm node while the I/O die will be based on the more mature 6nm process.
Meanwhile, NVIDIA’s next-gen AD102 die is also being internally tested. This GPU will power the RTX 4080 and 4090 will offer roughly twice as much performance as the GA102 “Ampere” die. The GeForce RTX 4090 is going to come with 24GB of 24Gbps GDDR6X memory paired with 96MB of L2 cache across a 384-bit bus. The RTX 4080 is expected to feature 12 or 16GB of GDDR6X memory across a 320-bit bus and 80-88MB of L2 cache. This GPU will feature around 14,000 FP32 cores, a slight cut from the 15-16K shaders on the RTX 4090, and a total of 18,432 on the AD102 die. As for the RTX 4070, we’re looking at 12 or 16GB of GDDR6 memory across a 256-bit bus. It will be based on the AD104-400 die and pack up to 10,000 FP32 cores. Finally, the RTX 4070, 4080, and 4090 will have a TGP of 400W, 500W, and 600W, respectively.
