AMD Radeon RX 7700 XT, 7900 XT Enter Mass Production, Launch Expected in October-November

AMD’s next-gen Radeon RX 7000 GPUs are set to enter mass production this month, followed by shipments of the GPU kits to board partners in September. The graphics cards are likely to hit retail during the holiday season with an October or November launch. As reported earlier, the first GPU to be launched will be the Radeon RX 7700 XT, then the RX 7900 XT, and finally the RX 7800 XT.

The RDNA 3 architecture may look less appealing as NVIDIA will be launching its 40 series lineup starting with the RTX 4090, and the 4080 and 4070 in the next two consecutive months. The Radeon RX 7700 XT will be a monolithic design unlike the 7800 XT and the 7900 XT. Furthermore, the Navi 33 die powering it will be based on the TSMC N6 node rather than N5.

The Radeon RX 7700 XT will compete with the likes of the GeForce RTX 4070. It will reportedly come with an 8GB VRAM buffer paired with a 128-bit bus along with 128MB of L3 “Infinity” cache. The core count is rumored to be 4,096 across 32 CUs and 16 WGPs. According to Tom from MLID, it’ll be faster than the Radeon RX 6900 XT at 1080p but fall behind at 4K due to the higher external bandwidth requirement. In ray-traced titles, however, you can expect markedly better performance than all the existing Radeon RX 6000 GPUs.

In terms of power consumption, the original TGP target was 200W but now has been increased to 230W. Interestingly, the RX 7700 XT will be equipped with an 8-lane PCIe Gen 5 bus which is more than sufficient considering the high bandwidth of Gen 4/Gen 5. However, users with older PCIe Gen 3 boards may run into bottlenecks.

The Radeon RX 7900 XT will be the highlight with a total of up to seven dies. One will be the GCD (Graphics Compute Die) while the remaining six will form the MCDs (memory/cache controller dies) paired with GDDR6 memory modules. The GCDs will be fabbed on TSMC’s 5nm node while the MCDs will be based on the more mature 6nm process. The GCD will pack a total of 12,288 shaders across 96 CUs and 48 WGPs. A total of 384MB of L3 “Infinity” Cache will be distributed across the six MCDs and paired with the memory controllers. The memory bus is said to be an impressive 384-bit wide, a first for the RDNA family. As expected from the N5 process, the boost clocks should easily hit 3GHz. And finally, the TDP should also increase, though not as much as Lovelace. A 350W TGP for the RX 7900 XT is my guess.

The Radeon RX 7800 XT will launch early next year as the 7900 XT and the 7700 XT battle the RTX 4090, and 4080, respectively. I have to say. AMD’s launch order certainly is confusing, to say the least. NVIDIA will have the entire floor to itself till the RX 7900 XT launches in December or January.
