GeForce 8600 GT 512MB DDR2 vs GeForce RTX 3090

Intro

The GeForce 8600 GT 512MB DDR2 uses a 80 nm design. nVidia has set the core frequency at 540 MHz. The DDR2 memory is set to run at a speed of 400 MHz on this particular card. It features 32 SPUs as well as 16 TAUs and 8 ROPs.

Compare that to the GeForce RTX 3090, which comes with GPU clock speed of 1395 MHz, and 24576 MB of GDDR6X memory set to run at 1219 MHz through a 384-bit bus. It also is comprised of 10496 Stream Processors, 328 Texture Address Units, and 112 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one 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 this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 max fill rate.
