Geforce GTX 770 vs Radeon HD 5750 1GB

Intro

Compare all of that to the Radeon HD 5750 1GB, which has a GPU core clock speed of 700 MHz, and 1024 MB of GDDR5 memory running at 1150 MHz through a 128-bit bus. It also is comprised of 720(144x5) SPUs, 36 Texture Address Units, and 16 ROPs.

Pixel Rate

The Geforce GTX 770 will be quite a bit (more or less 199%) more effective at FSAA than the Radeon HD 5750 1GB, and able to handle higher resolutions without losing too much performance. (explain)

Geforce GTX 770		33472 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 22272 (199%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
