GeForce 8600 GT 512MB DDR2 vs GeForce RTX 4080

Intro

The GeForce 8600 GT 512MB DDR2 makes use of a 80 nm design. nVidia has clocked the core speed at 540 MHz. The DDR2 memory is set to run at a speed of 400 MHz on this specific card. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Compare all that to the GeForce RTX 4080, which features a core clock speed of 2205 MHz and a GDDR6X memory speed of 1400 MHz. It also features a 256-bit bus, and uses a 4 nm design. It is comprised of 9728 SPUs, 304 Texture Address Units, and 112 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure 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 outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
