GeForce GTX 295 vs GeForce GTX 950

Intro

Compare all of that to the GeForce GTX 950, which comes with core clock speeds of 1024 MHz on the GPU, and 1652 MHz on the 2048 MB of GDDR5 RAM. It features 768 SPUs as well as 48 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950		90 Watts
GeForce GTX 295		289 Watts
	Difference: 199 Watts (221%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 295 should in theory be a lot better than the GeForce GTX 950 in general. (explain)

GeForce GTX 295		223776 MB/sec
GeForce GTX 950		105728 MB/sec
	Difference: 118048 (112%)

Texel Rate

The GeForce GTX 295 should be a lot (about 88%) more effective at anisotropic filtering than the GeForce GTX 950. (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GTX 950		49152 Mtexels/sec
	Difference: 43008 (88%)

Pixel Rate

The GeForce GTX 950 will be a bit (approximately 2%) more effective at anti-aliasing than the GeForce GTX 295, and should be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GTX 295		32256 Mpixels/sec
	Difference: 512 (2%)

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 data (in units of MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 applied in one second. This is worked out by multiplying the total amount of texture units by the core 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant 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.
