GeForce GTX 295 vs GeForce GTX Titan

Intro

Compare that to the GeForce GTX Titan, which has a core clock frequency of 837 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 384-bit memory bus, and uses a 28 nm design. It features 2688 SPUs, 224 Texture Address Units, and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The GeForce GTX Titan should theoretically perform a lot faster than the GeForce GTX 295 overall. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce GTX 295		223776 MB/sec
	Difference: 64608 (29%)

Texel Rate

The GeForce GTX Titan will be quite a bit (approximately 103%) more effective at AF than the GeForce GTX 295. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce GTX 295		92160 Mtexels/sec
	Difference: 95328 (103%)

Pixel Rate

The GeForce GTX Titan should be much (about 25%) better at full screen anti-aliasing than the GeForce GTX 295, and should be capable of handling higher resolutions more effectively. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce GTX 295		32256 Mpixels/sec
	Difference: 7920 (25%)

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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can 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 card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
