GeForce GTX 295 vs GeForce GTX Titan X

Intro

Compare those specs to the GeForce GTX Titan X, which features a GPU core clock speed of 1000 MHz, and 12288 MB of GDDR5 memory running at 1750 MHz through a 384-bit bus. It also is comprised of 3072 SPUs, 192 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX Titan X		250 Watts
GeForce GTX 295		289 Watts
	Difference: 39 Watts (16%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan X should be 50% faster than the GeForce GTX 295 in general, due to its greater bandwidth. (explain)

GeForce GTX Titan X		336000 MB/sec
GeForce GTX 295		223776 MB/sec
	Difference: 112224 (50%)

Texel Rate

The GeForce GTX Titan X will be quite a bit (more or less 108%) faster with regards to texture filtering than the GeForce GTX 295. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
GeForce GTX 295		92160 Mtexels/sec
	Difference: 99840 (108%)

Pixel Rate

The GeForce GTX Titan X will be much (approximately 198%) faster with regards to FSAA than the GeForce GTX 295, and capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
GeForce GTX 295		32256 Mpixels/sec
	Difference: 63744 (198%)

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 max amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
