AMD is expected to launch the Radeon RX 7600 XT next month to bridge the gap with the RX 7700 XT. The registration data points to a 16GB memory buffer paired with a 256-bit bus, up from the previously expected 12GB plus 192-bit bus. However, given the target resolution and framerates, a 256-bit wide memory bus for a 600-class SKU would count as weird.
The Radeon RX 6600 XT, 6650 XT, and their GeForce rivals feature a 128-bit bus backed by a small cache buffer. Even the RX 7700 XT and the RTX 4070 are equipped with a 192-bit bus instead of a 256-bit solution. Therefore, I’d take this info with a grain of salt.
The shader configuration of the 7600 XT should be beefier than the 7600, which implies using a heavily disabled Navi 32 GPU. The latter already utilizes the fully enabled Navi 33 core. A shader count of 2,560 across 40 Compute Units (CUs) would be a viable option backed by a 40MB “L3” cache buffer. The core clocks should be the same as the existing RDNA 3 parts with a TBP of roughly ~200W.
The Radeon RX 7600 XT is expected to launch on the 22nd of January at an MSRP of $349 alongside the RTX 4070 Ti Super.
