GeForce GTX 465 vs GeForce GTX 750 Ti

Intro

Compare all of that to the GeForce GTX 750 Ti, which uses a 28 nm design. nVidia has set the core speed at 1020 MHz. The GDDR5 memory is set to run at a frequency of 1350 MHz on this specific model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

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 perform a small bit faster than the GeForce GTX 750 Ti in general. (explain)

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

Texel Rate

The GeForce GTX 750 Ti is quite a bit (about 53%) better at texture 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

The GeForce GTX 465 should be a small bit (more or less 19%) faster with regards to FSAA than the GeForce GTX 750 Ti, and should be capable of handling higher screen resolutions while still performing well. (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: Bandwidth is the max amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant 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.
