GeForce 8600 GT 512MB DDR2 vs GeForce RTX 3070

Intro

The GeForce 8600 GT 512MB DDR2 features a GPU clock speed of 540 MHz, and the 512 MB of DDR2 RAM runs at 400 MHz through a 128-bit bus. It also features 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the GeForce RTX 3070, which features a clock speed of 1500 MHz and a GDDR6 memory speed of 1750 MHz. It also makes use of a 256-bit bus, and uses a 8 nm design. It features 5888 SPUs, 184 Texture Address Units, and 96 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
