GeForce 8800 GTS (G80) 640MB vs Radeon RX 7900 XT

Intro

Compare all of that to the Radeon RX 7900 XT, which uses a 5 nm design. AMD has set the core speed at 1500 MHz. The GDDR6 RAM works at a speed of 2500 MHz on this specific model. It features 5376 SPUs along with 336 TAUs and 192 Rasterization Operator Units.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
