GeForce 8800 GTS (G92) vs Radeon HD 5750 1GB

Intro

Compare all of that to the Radeon HD 5750 1GB, which uses a 40 nm design. AMD has clocked the core frequency at 700 MHz. The GDDR5 RAM works at a frequency of 1150 MHz on this particular card. It features 720(144x5) SPUs along with 36 Texture Address Units and 16 ROPs.

GeForce 8800 GTS (G92)		41600 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 16400 (65%)

Pixel Rate

The Radeon HD 5750 1GB is a small bit (approximately 8%) better at full screen anti-aliasing than the GeForce 8800 GTS (G92), and also will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon HD 5750 1GB		11200 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 800 (8%)

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 max amount of data (in units of MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 amount of texture map elements (texels) that are applied per 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 better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
