AMD Radeon RX 6600 XT to Feature Just 32MB of Infinity Cache and 8GB of VRAM

According to info received by @mooreslawisdead, AMD’s upcoming GPU, the Radeon RX 6600 XT will feature just 32 MB of L3 (Infinity Cache) along with an 8GB VRAM buffer. In comparison, the Navi 22-based RX 6700 XT packs 96MB of LLC while the Big Navi (Navi 21) SKUs come with 128MB of L3 cache. Considering that the GPU is targeted at 1080p gaming, this shouldn’t be a big deal but might result in a lackluster performance at 1440p, especially considering the narrow 128-bit bus.

In terms of raw compute power, the Navi 23 die will feature up to 32 CUs or 2,048 shaders running at a boost clock of up to 2,700 MHz. When the 8GB 16Gbps memory is paired with a 128-bit bus, you get an overall memory bandwidth of just 256 GB/s which pales in comparison to the 360 GB/s found on the GeForce RTX 3060. As such, the latter should have a notable advantage at 1440p, similar to how the RX 6700 XT-RTX 3070 scenario plays out.

Another interesting tidbit regarding the RX 6600 XT is that it’ll only feature 8 PCIe lanes. While this won’t be an issue on desktop PCs that support the newer PCIe 4.0 interface, on older systems and laptops that are limited to PCIe 3.0, this might lead to a slight bottleneck.
