GeForce GTX 260 vs Radeon HD 5750 1GB

Intro

Compare all of that to the Radeon HD 5750 1GB, which comes with a clock speed of 700 MHz and a GDDR5 memory frequency of 1150 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It features 720(144x5) SPUs, 36 TAUs, and 16 ROPs.

Radeon HD 5750 1GB		86 Watts
GeForce GTX 260		182 Watts
	Difference: 96 Watts (112%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 260 should in theory be quite a bit better than the Radeon HD 5750 1GB in general. (explain)

GeForce GTX 260		111888 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 38288 (52%)

Texel Rate

The GeForce GTX 260 is much (more or less 46%) more effective at anisotropic filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTX 260		36864 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 11664 (46%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 260 is a better choice, by far. (explain)

GeForce GTX 260		16128 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 4928 (44%)

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 information (counted in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 can be applied per second. This figure is worked out 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 handling 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 the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out 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 filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
