Radeon RX 6950 XT vs Radeon RX Vega 64
Intro
The Radeon RX 6950 XT features a clock speed of 1925 MHz and a GDDR6 memory speed of 2250 MHz. It also makes use of a 256-bit bus, and makes use of a 7 nm design. It is comprised of 5120 SPUs, 320 Texture Address Units, and 128 Raster Operation Units.Compare those specs to the Radeon RX Vega 64, which comes with core speeds of 1247 MHz on the GPU, and 1890 MHz on the 8192 MB of HBM2 RAM. It features 4096 SPUs along with 256 TAUs and 64 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
