GeForce GTX 650 Ti 2GB vs Radeon HD 5750 512MB

Intro

The GeForce GTX 650 Ti 2GB features a GPU core speed of 928 MHz, and the 2048 MB of GDDR5 RAM runs at 1350 MHz through a 128-bit bus. It also is comprised of 768 SPUs, 64 TAUs, and 16 Raster Operation Units.

Compare those specifications to the Radeon HD 5750 512MB, which features a core clock frequency of 700 MHz and a GDDR5 memory speed of 1150 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It features 720(144x5) SPUs, 36 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
