GeForce 8600 GT 512MB DDR2 vs GeForce RTX 3090

Intro

The GeForce 8600 GT 512MB DDR2 uses a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The DDR2 RAM works at a speed of 400 MHz on this specific card. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.

Compare those specs to the GeForce RTX 3090, which has a core clock speed of 1395 MHz and a GDDR6X memory speed of 1219 MHz. It also makes use of a 384-bit memory bus, and makes use of a 8 nm design. It is comprised of 10496 SPUs, 328 Texture Address Units, and 112 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount 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 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 the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
