GeForce GTX 295 vs Radeon HD 6750 1GB

Intro

Compare all that 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 is set to run at a speed of 1000 MHz on this specific card. It features 720 SPUs as well as 36 TAUs and 16 ROPs.

Radeon HD 6750 1GB		86 Watts
GeForce GTX 295		289 Watts
	Difference: 203 Watts (236%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 295 should perform quite a bit faster than the Radeon HD 6750 1GB in general. (explain)

GeForce GTX 295		223776 MB/sec
Radeon HD 6750 1GB		64000 MB/sec
	Difference: 159776 (250%)

Texel Rate

The GeForce GTX 295 should be a lot (more or less 253%) better at texture filtering than the Radeon HD 6750 1GB. (explain)

GeForce GTX 295		92160 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 66060 (253%)

Pixel Rate

The GeForce GTX 295 should be a lot (approximately 178%) better at anti-aliasing than the Radeon HD 6750 1GB, and also capable of handling higher resolutions while still performing well. (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 largest amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the 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 amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
