GeForce GTX 275 vs Geforce GTX 760

Intro

Compare all that to the Geforce GTX 760, which comes with core clock speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 1152 SPUs as well as 96 TAUs and 32 ROPs.

Memory Bandwidth

The Geforce GTX 760, in theory, should perform much faster than the GeForce GTX 275 in general. (explain)

Geforce GTX 760		192256 MB/sec
GeForce GTX 275		127008 MB/sec
	Difference: 65248 (51%)

Texel Rate

The Geforce GTX 760 should be quite a bit (about 86%) better at texture filtering than the GeForce GTX 275. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GTX 275		50640 Mtexels/sec
	Difference: 43440 (86%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Geforce GTX 760 is the winner, by a large margin. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce GTX 275		17724 Mpixels/sec
	Difference: 13636 (77%)

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: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
