GeForce 8600 GT 1GB DDR2 vs Radeon HD 7750

Intro

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

Radeon HD 7750		55 Watts
	Difference: 8 Watts (17%)

Memory Bandwidth

As far as performance goes, the Radeon HD 7750 should theoretically be quite a bit better than the GeForce 8600 GT 1GB DDR2 overall. (explain)

Radeon HD 7750		72000 MB/sec
GeForce 8600 GT 1GB DDR2		12800 MB/sec
	Difference: 59200 (463%)

Texel Rate

The Radeon HD 7750 is a lot (approximately 196%) faster with regards to texture filtering than the GeForce 8600 GT 1GB DDR2. (explain)

Radeon HD 7750		25600 Mtexels/sec
GeForce 8600 GT 1GB DDR2		8640 Mtexels/sec
	Difference: 16960 (196%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 7750 is a better choice, and very much so. (explain)

Radeon HD 7750		12800 Mpixels/sec
GeForce 8600 GT 1GB DDR2		4320 Mpixels/sec
	Difference: 8480 (196%)

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 moved across the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
