GeForce GTX 295 vs GeForce GTX 970

Intro

Compare all of that to the GeForce GTX 970, which has a GPU core clock speed of 1050 MHz, and 4096 MB of GDDR5 memory running at 1750 MHz through a 256-bit bus. It also is made up of 1664 Stream Processors, 104 TAUs, and 64 ROPs.

As far as performance goes, the GeForce GTX 970 should theoretically be a bit superior to the GeForce GTX 295 in general. (explain)

GeForce GTX 970		224000 MB/sec
GeForce GTX 295		223776 MB/sec
	Difference: 224 (0%)

Texel Rate

The GeForce GTX 970 should be a small bit (more or less 18%) more effective at AF than the GeForce GTX 295. (explain)

GeForce GTX 970		109200 Mtexels/sec
GeForce GTX 295		92160 Mtexels/sec
	Difference: 17040 (18%)

Pixel Rate

The GeForce GTX 970 is quite a bit (more or less 108%) faster with regards to FSAA than the GeForce GTX 295, and also capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 970		67200 Mpixels/sec
GeForce GTX 295		32256 Mpixels/sec
	Difference: 34944 (108%)

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 maximum amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 are applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
