GeForce GTS 150 vs GeForce GTX 750 Ti

Intro

Compare all that to the GeForce GTX 750 Ti, which comes with GPU clock speed of 1020 MHz, and 2048 MB of GDDR5 memory set to run at 1350 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
GeForce GTS 150		141 Watts
	Difference: 81 Watts (135%)

Memory Bandwidth

In theory, the GeForce GTX 750 Ti should be 170% quicker than the GeForce GTS 150 overall, due to its higher bandwidth. (explain)

GeForce GTX 750 Ti		86400 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 54400 (170%)

Texel Rate

The GeForce GTS 150 is a little bit (more or less 16%) better at texture filtering than the GeForce GTX 750 Ti. (explain)

GeForce GTS 150		47360 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 6560 (16%)

Pixel Rate

The GeForce GTX 750 Ti is quite a bit (more or less 38%) better at FSAA than the GeForce GTS 150, and also will be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 4480 (38%)

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 largest amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
