GeForce 8800 GTS (G92) vs Radeon HD 5770

Intro

The GeForce 8800 GTS (G92) uses a 65 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR3 memory works at a frequency of 970 MHz on this specific card. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.

Compare those specifications to the Radeon HD 5770, which comes with a clock speed of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is comprised of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

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

Pixel Rate: Pixel rate is the most pixels that 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 number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
