GeForce GTX 750 vs GeForce GTX 750 Ti

Intro

Compare those specifications to the GeForce GTX 750 Ti, which features GPU core 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 Stream Processors, 40 TAUs, and 16 ROPs.

Power Consumption (Max TDP)

GeForce GTX 750		55 Watts
GeForce GTX 750 Ti		60 Watts
	Difference: 5 Watts (9%)

Memory Bandwidth

In theory, the GeForce GTX 750 Ti should perform a bit faster than the GeForce GTX 750 in general. (explain)

GeForce GTX 750 Ti		86400 MB/sec
GeForce GTX 750		80000 MB/sec
	Difference: 6400 (8%)

Texel Rate

The GeForce GTX 750 Ti should be quite a bit (approximately 25%) more effective at texture filtering than the GeForce GTX 750. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 8160 (25%)

Pixel Rate

Both cards have exactly the same pixel fill rate, so in theory they should be equally good at at AA, and be able to handle the same screen resolutions. (explain)

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 MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock 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 lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
