GeForce 8800 GTS (G92) vs Radeon HD 7750

Intro

Compare those specifications to the Radeon HD 7750, which makes use of a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory works at a speed of 1125 MHz on this specific model. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7750		55 Watts
GeForce 8800 GTS (G92)		135 Watts
	Difference: 80 Watts (145%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 7750 is 16% quicker than the GeForce 8800 GTS (G92) in general, due to its higher data rate. (explain)

Radeon HD 7750		72000 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 9920 (16%)

Texel Rate

The GeForce 8800 GTS (G92) will be a lot (approximately 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 will be quite a bit (about 23%) more effective at FSAA than the GeForce 8800 GTS (G92), and should be able to handle higher screen 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 (counted in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's 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 texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
