GeForce GTX 460 (OEM) vs Radeon HD 4750

Intro

The GeForce GTX 460 (OEM) comes with a GPU core speed of 650 MHz, and the 1024 MB of GDDR5 memory runs at 850 MHz through a 256-bit bus. It also is comprised of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.

Compare those specs to the Radeon HD 4750, which features a clock frequency of 730 MHz and a GDDR5 memory speed of 800 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It features 640(128x5) SPUs, 32 TAUs, and 16 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
