GeForce GTX 465 vs GeForce GTX 750 Ti

Intro

Compare those specifications to the GeForce GTX 750 Ti, which features core speeds of 1020 MHz on the GPU, and 1350 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
GeForce GTX 465		200 Watts
	Difference: 140 Watts (233%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 465 should be 19% quicker than the GeForce GTX 750 Ti in general, because of its greater data rate. (explain)

GeForce GTX 465		102592 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 16192 (19%)

Texel Rate

The GeForce GTX 750 Ti will be much (more or less 53%) faster with regards to anisotropic filtering than the GeForce GTX 465. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 14092 (53%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 465 is a better choice, though not by far. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce GTX 750 Ti		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 largest amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
