GeForce GTX 260 vs Radeon HD 6750

Intro

Compare those specs to the Radeon HD 6750, which features a core clock speed of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is comprised of 720 SPUs, 36 Texture Address Units, and 16 ROPs.

Radeon HD 6750		64000 MB/sec
	Difference: 47888 (75%)

Texel Rate

The GeForce GTX 260 should be quite a bit (more or less 41%) better at anisotropic filtering than the Radeon HD 6750. (explain)

GeForce GTX 260		36864 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 10764 (41%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 260 is superior to the Radeon HD 6750, and very much so. (explain)

GeForce GTX 260		16128 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 4528 (39%)

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 information (measured in megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics 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 number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
