GeForce GTX 750 vs Radeon HD 5770

Intro

The GeForce GTX 750 features a core clock frequency of 1020 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is made up of 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

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

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at 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 chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
