GeForce GTX 1070 vs GeForce GTX 295

Intro

Compare all that to the GeForce GTX 295, which uses a 55 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 memory is set to run at a speed of 999 MHz on this particular card. It features 240 SPUs as well as 80 Texture Address Units and 28 Rasterization Operator Units.

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

Memory Bandwidth

In theory, the GeForce GTX 1070 should be a small bit faster than the GeForce GTX 295 in general. (explain)

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

Texel Rate

The GeForce GTX 1070 should be a lot (approximately 96%) more effective at AF 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 a high screen resolution is important to you, then the GeForce GTX 1070 is the winner, and very much so. (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: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock 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 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 maximum fill rate.
