GeForce 9800 GTX+ vs GeForce GTX 750 Ti

Intro

Compare those specs to the GeForce GTX 750 Ti, which features core clock speeds of 1020 MHz on the GPU, and 1350 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
GeForce 9800 GTX+		145 Watts
	Difference: 85 Watts (142%)

Memory Bandwidth

Theoretically, the GeForce GTX 750 Ti should be quite a bit faster than the GeForce 9800 GTX+ in general. (explain)

GeForce GTX 750 Ti		86400 MB/sec
GeForce 9800 GTX+		70400 MB/sec
	Difference: 16000 (23%)

Texel Rate

The GeForce 9800 GTX+ will be a little bit (approximately 16%) better at anisotropic filtering than the GeForce GTX 750 Ti. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 6432 (16%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 750 Ti is the winner, and very much so. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
GeForce 9800 GTX+		11808 Mpixels/sec
	Difference: 4512 (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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's interface 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 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at 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 card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
