GeForce GTX 590 vs Radeon HD 6750

Intro

Compare those specifications to the Radeon HD 6750, which features a GPU core clock speed of 725 MHz, and 512 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is made up of 720 Stream Processors, 36 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6750		86 Watts
GeForce GTX 590		365 Watts
	Difference: 279 Watts (324%)

Memory Bandwidth

In theory, the GeForce GTX 590 is 413% quicker than the Radeon HD 6750 in general, because of its greater bandwidth. (explain)

GeForce GTX 590		328320 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 264320 (413%)

Texel Rate

The GeForce GTX 590 is quite a bit (about 198%) faster with regards to anisotropic filtering than the Radeon HD 6750. (explain)

GeForce GTX 590		77696 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 51596 (198%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 590 is a better choice, and very much so. (explain)

GeForce GTX 590		58272 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 46672 (402%)

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 information (measured in MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core 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 processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
