GeForce GTX 295 vs Geforce GTX 760

Intro

Compare those specs to the Geforce GTX 760, which has a GPU core clock speed of 980 MHz, and 2048 MB of GDDR5 memory set to run at 1502 MHz through a 256-bit bus. It also is comprised of 1152 SPUs, 96 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 760		170 Watts
GeForce GTX 295		289 Watts
	Difference: 119 Watts (70%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 295 is 16% quicker than the Geforce GTX 760 overall, because of its higher bandwidth. (explain)

GeForce GTX 295		223776 MB/sec
Geforce GTX 760		192256 MB/sec
	Difference: 31520 (16%)

Texel Rate

The Geforce GTX 760 should be a little bit (about 2%) faster with regards to AF than the GeForce GTX 295. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GTX 295		92160 Mtexels/sec
	Difference: 1920 (2%)

Pixel Rate

The GeForce GTX 295 will be a little bit (more or less 3%) more effective at full screen anti-aliasing than the Geforce GTX 760, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 295		32256 Mpixels/sec
Geforce GTX 760		31360 Mpixels/sec
	Difference: 896 (3%)

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 (counted in MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
