GeForce GTX 295 vs Radeon HD 6750 1GB

Intro

Compare those specs to the Radeon HD 6750 1GB, which makes use of a 40 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this particular card. It features 720 SPUs along with 36 Texture Address Units and 16 ROPs.

Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 66060 (253%)

Pixel Rate

The GeForce GTX 295 should be quite a bit (about 178%) faster with regards to FSAA than the Radeon HD 6750 1GB, and able to handle higher resolutions more effectively. (explain)

GeForce GTX 295		32256 Mpixels/sec
Radeon HD 6750 1GB		11600 Mpixels/sec
	Difference: 20656 (178%)

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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transported 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 the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 are processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
