GeForce GTX 590 vs Radeon HD 5750 1GB

Intro

Compare all that to the Radeon HD 5750 1GB, which uses a 40 nm design. AMD has clocked the core frequency at 700 MHz. The GDDR5 RAM works at a speed of 1150 MHz on this card. It features 720(144x5) SPUs as well as 36 TAUs and 16 ROPs.

GeForce GTX 590		365 Watts
	Difference: 279 Watts (324%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 590 is 346% quicker than the Radeon HD 5750 1GB in general, because of its higher bandwidth. (explain)

GeForce GTX 590		328320 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 254720 (346%)

Texel Rate

The GeForce GTX 590 should be a lot (approximately 208%) faster with regards to texture filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTX 590		77696 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 52496 (208%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 590 is the winner, and very much so. (explain)

GeForce GTX 590		58272 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 47072 (420%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
