GeForce 8800 GTS (G92) vs Radeon HD 7750

Intro

Compare those specifications to the Radeon HD 7750, which uses a 28 nm design. ATi has set the core frequency at 800 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this particular card. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 9920 (16%)

Texel Rate

The GeForce 8800 GTS (G92) should be a lot (more or less 63%) better at anisotropic filtering than the Radeon HD 7750. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 16000 (63%)

Pixel Rate

The Radeon HD 7750 is a lot (more or less 23%) more effective at full screen anti-aliasing than the GeForce 8800 GTS (G92), and also capable of handling higher resolutions without losing too much performance. (explain)

Radeon HD 7750		12800 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 2400 (23%)

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: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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