GeForce 8800 GT 256MB vs Radeon R9 M290X

Intro

The GeForce 8800 GT 256MB uses a 65 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 memory is set to run at a frequency of 700 MHz on this model. It features 112 SPUs as well as 56 TAUs and 16 ROPs.

Compare all that to the Radeon R9 M290X, which features GPU clock speed of 850 MHz, and 4096 MB of GDDR5 RAM set to run at 1200 MHz through a 256-bit bus. It also is comprised of 1280 SPUs, 80 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate 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 output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
