GeForce 8600 GT 1GB GDDR3 vs GeForce RTX 3090

Intro

The GeForce 8600 GT 1GB GDDR3 has a GPU core clock speed of 540 MHz, and the 1024 MB of GDDR3 memory is set to run at 700 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 TAUs, and 8 ROPs.

Compare those specifications to the GeForce RTX 3090, which comes with a clock speed of 1395 MHz and a GDDR6X memory frequency of 1219 MHz. It also features a 384-bit memory bus, and makes use of a 8 nm design. It is made up of 10496 SPUs, 328 Texture Address Units, and 112 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 number of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video 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 colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
