GeForce GTX 295 vs Nvidia Titan X

Intro

Compare those specifications to the Nvidia Titan X, which has a core clock speed of 1417 MHz and a GDDR5X memory speed of 1251 MHz. It also makes use of a 384-bit bus, and uses a 16 nm design. It is made up of 3584 SPUs, 224 TAUs, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The Nvidia Titan X, in theory, should be quite a bit faster than the GeForce GTX 295 overall. (explain)

GeForce GTX 295		223776 MB/sec
	Difference: 267744 (120%)

Texel Rate

The Nvidia Titan X is a lot (approximately 244%) better at texture filtering than the GeForce GTX 295. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GTX 295		92160 Mtexels/sec
	Difference: 225248 (244%)

Pixel Rate

If running with a high resolution is important to you, then the Nvidia Titan X is the winner, and very much so. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GTX 295		32256 Mpixels/sec
	Difference: 103776 (322%)

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 information (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
