GeForce GTX 1070 vs GeForce GTX 295

Intro

Compare those specs to the GeForce GTX 295, which has a GPU core clock speed of 576 MHz, and 896 MB of GDDR3 memory set to run at 999 MHz through a 448-bit bus. It also is comprised of 240 SPUs, 80 Texture Address Units, and 28 ROPs.

GeForce GTX 1070		150 Watts
GeForce GTX 295		289 Watts
	Difference: 139 Watts (93%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1070 is 17% quicker than the GeForce GTX 295 overall, because of its greater bandwidth. (explain)

GeForce GTX 1070		262144 MB/sec
GeForce GTX 295		223776 MB/sec
	Difference: 38368 (17%)

Texel Rate

The GeForce GTX 1070 will be a lot (more or less 96%) better at texture filtering than the GeForce GTX 295. (explain)

GeForce GTX 1070		180720 Mtexels/sec
GeForce GTX 295		92160 Mtexels/sec
	Difference: 88560 (96%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 1070 is superior to the GeForce GTX 295, by a large margin. (explain)

GeForce GTX 1070		96384 Mpixels/sec
GeForce GTX 295		32256 Mpixels/sec
	Difference: 64128 (199%)

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 information (measured in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
