GeForce 8600 GT 1GB GDDR3 vs GeForce RTX 4080

Intro

The GeForce 8600 GT 1GB GDDR3 features a core clock speed of 540 MHz and a GDDR3 memory frequency of 700 MHz. It also makes use of a 128-bit bus, and uses a 80 nm design. It features 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Compare all that to the GeForce RTX 4080, which comes with a GPU core clock speed of 2205 MHz, and 16384 MB of GDDR6X RAM running at 1400 MHz through a 256-bit bus. It also features 9728 Stream Processors, 304 Texture Address Units, and 112 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transported over the external memory interface in 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 better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
