Radeon R9 270 vs Radeon RX 6950 XT

Intro

The Radeon R9 270 makes use of a 28 nm design. AMD has clocked the core speed at 900 MHz. The GDDR5 RAM is set to run at a frequency of 1400 MHz on this particular card. It features 1280 SPUs as well as 80 TAUs and 32 ROPs.

Compare all that to the Radeon RX 6950 XT, which has core speeds of 1925 MHz on the GPU, and 2250 MHz on the 16384 MB of GDDR6 memory. It features 5120 SPUs as well as 320 TAUs and 128 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
