GeForce GTX 460 SE vs Radeon HD 5750 1GB

Intro

Compare all of that to the Radeon HD 5750 1GB, which has a GPU core clock speed of 700 MHz, and 1024 MB of GDDR5 RAM running at 1150 MHz through a 128-bit bus. It also features 720(144x5) Stream Processors, 36 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5750 1GB		86 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 64 Watts (74%)

Memory Bandwidth

In theory, the GeForce GTX 460 SE will be 48% faster than the Radeon HD 5750 1GB overall, because of its greater bandwidth. (explain)

GeForce GTX 460 SE		108800 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 35200 (48%)

Texel Rate

The GeForce GTX 460 SE is a lot (approximately 24%) faster with regards to texture filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 6000 (24%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 460 SE is a better choice, by far. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 9600 (86%)

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 largest amount of data (counted in MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
