GeForce GTX 465 vs GeForce GTX 750

Intro

Compare those specifications to the GeForce GTX 750, which has GPU core speed of 1020 MHz, and 1024 MB of GDDR5 memory running at 1250 MHz through a 128-bit bus. It also is comprised of 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750		55 Watts
GeForce GTX 465		200 Watts
	Difference: 145 Watts (264%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 465 should be 28% faster than the GeForce GTX 750 overall, due to its higher bandwidth. (explain)

GeForce GTX 465		102592 MB/sec
GeForce GTX 750		80000 MB/sec
	Difference: 22592 (28%)

Texel Rate

The GeForce GTX 750 will be much (about 22%) better at AF than the GeForce GTX 465. (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 5932 (22%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 465 is the winner, but not by far. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce GTX 750		16320 Mpixels/sec
	Difference: 3104 (19%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
