AMD Radeon RX 7800XT 16GB From ASRock Spotted in the EEU Portal

The Radeon RX 7800XT has been spotted in the Eurasian Economic Union portal for the first time. The budget RDNA 3 GPU, with allegedly 16GB of GDDR6 memory, is expected to launch in the coming weeks (by the end of the quarter). The SKUs spotted are board partner variants from the ASRock Phantom Gaming lineup, including a new Phantom Gaming W (Watercooled?) model.


Powered by the Navi 32 GPU, the Radeon RX 7800 XT will go up against NVIDIA’s GeForce RTX 4070 and RTX 4070 Ti (mostly the former). It features the same MCDs (Memory Complex Dies) as Navi 31 with a 64-bit controller and 16MB of L3 “Infinity” Cache per die. The Navi 32 GCD should measure up to 200mm^sq, roughly 50% less than the Navi 31 GCD, which has an area of 304.35mm^sq. Subtracting the area of the two MCDs (37.5mm^sq each), you get a die ~175mm^sq sm or 33% smaller.

The fully enabled Navi 32 die packs 4,096 shaders or 64 Compute Units (CUs), with 64MB of L3 cache and a 256-bit memory controller. It also features 256 Texture Units and 128 Raster Output Units alongside 64 RT Cores (one per CU). The GPU has a TBP of 300W and a boost clock of almost 3GHz.

The Radeon RX 7800 XT ought to be the fastest Navi 32-based card. It should use a full-fledged (or mostly full-fledged) Navi 32 die. The RX 7800 will be the second SKU to leverage the midrange RDNA 3 die. It will consist of 60 Compute Units (CU) or 30 Workgroup Processors (WGP) for 3,840 stream processors. The GPU will be paired with a 16GB VRAM buffer across a 256-bit bus alongside a 64MB L3 cache buffer. The TBP is said to be approximately 285W.

The Radeon RX 7800M XT is the mobile counterpart of the RX 7800 series. It should have the same base specifications as the RX 7800. As per a recent leak, the 7800M XT nets a score of 17,842 in the 3DMark TimeSpy graphics test. This places it on par with NVIDIA’s GeForce RTX 4070 desktop or a GeForce RTX 4080 mobile.
