GeForce GT 450 (OEM) vs GeForce GTX 750 Ti

Intro

Compare that to the GeForce GTX 750 Ti, which has a clock frequency of 1020 MHz and a GDDR5 memory frequency of 1350 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 ROPs.

GeForce GTX 750 Ti		60 Watts
GeForce GT 450 (OEM)		106 Watts
	Difference: 46 Watts (77%)

Memory Bandwidth

The GeForce GT 450 (OEM), in theory, should perform a bit faster than the GeForce GTX 750 Ti in general. (explain)

GeForce GT 450 (OEM)		96000 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 9600 (11%)

Texel Rate

The GeForce GTX 750 Ti will be quite a bit (more or less 115%) faster with regards to texture filtering than the GeForce GT 450 (OEM). (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 21840 (115%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GT 450 (OEM) is a better choice, not by a very large margin though. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
GeForce GTX 750 Ti		16320 Mpixels/sec
	Difference: 2640 (16%)

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 moved over the external memory interface in one second. It's worked out by multiplying the card's bus 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 card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
