GeForce GTX 295 vs GeForce GTX 970

Intro

The GeForce GTX 295 features a clock speed of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also features a 448-bit memory bus, and uses a 55 nm design. It is made up of 240 SPUs, 80 Texture Address Units, and 28 Raster Operation Units.

Compare those specs to the GeForce GTX 970, which makes use of a 28 nm design. nVidia has set the core speed at 1050 MHz. The GDDR5 memory works at a frequency of 1750 MHz on this specific card. It features 1664 SPUs along with 104 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 970 145 Watts
GeForce GTX 295 289 Watts
Difference: 144 Watts (99%)

Memory Bandwidth

In theory, the GeForce GTX 970 will be 0% faster than the GeForce GTX 295 overall, because of its higher data rate. (explain)

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

Texel Rate

The GeForce GTX 970 is a bit (approximately 18%) more effective at anisotropic filtering 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 should be much (approximately 108%) faster with regards to full screen anti-aliasing than the GeForce GTX 295, and capable of handling higher resolutions better. (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.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a 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 number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
