GeForce GTX 260 Core 216 vs Radeon HD 6750

Intro

Compare all of that to the Radeon HD 6750, which comes with core speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 memory. It features 720 SPUs as well as 36 TAUs and 16 ROPs.

	Difference: 116 Watts (135%)

Memory Bandwidth

In theory, the GeForce GTX 260 Core 216 should be 75% quicker than the Radeon HD 6750 overall, due to its greater bandwidth. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 47888 (75%)

Texel Rate

The GeForce GTX 260 Core 216 is quite a bit (approximately 59%) better at AF than the Radeon HD 6750. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 15372 (59%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 260 Core 216 is a better choice, and very much so. (explain)

GeForce GTX 260 Core 216		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 maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
