GeForce GTX 295 vs GeForce GTX 750

Intro

Compare those specifications to the GeForce GTX 750, which uses a 28 nm design. nVidia has set the core frequency at 1020 MHz. The GDDR5 RAM works at a speed of 1250 MHz on this card. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750		55 Watts
GeForce GTX 295		289 Watts
	Difference: 234 Watts (425%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 295 should theoretically be a lot superior to the GeForce GTX 750 overall. (explain)

GeForce GTX 295		223776 MB/sec
GeForce GTX 750		80000 MB/sec
	Difference: 143776 (180%)

Texel Rate

The GeForce GTX 295 will be a lot (more or less 182%) more effective at AF than the GeForce GTX 750. (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 59520 (182%)

Pixel Rate

The GeForce GTX 295 should be much (about 98%) better at full screen anti-aliasing than the GeForce GTX 750, and will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GTX 750		16320 Mpixels/sec
	Difference: 15936 (98%)

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 largest amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If 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 amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
