GeForce 9800 GTX+ vs GeForce GTX 750

Intro

Compare all of that to the GeForce GTX 750, which has GPU core speed of 1020 MHz, and 1024 MB of GDDR5 RAM running at 1250 MHz through a 128-bit bus. It also features 512 Stream Processors, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750		55 Watts
GeForce 9800 GTX+		145 Watts
	Difference: 90 Watts (164%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 750 should theoretically be just a bit superior to the GeForce 9800 GTX+ in general. (explain)

GeForce GTX 750		80000 MB/sec
GeForce 9800 GTX+		70400 MB/sec
	Difference: 9600 (14%)

Texel Rate

The GeForce 9800 GTX+ will be quite a bit (about 45%) better at anisotropic filtering than the GeForce GTX 750. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 14592 (45%)

Pixel Rate

The GeForce GTX 750 should be a lot (more or less 38%) better at full screen anti-aliasing than the GeForce 9800 GTX+, and will be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 750		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 largest amount of data (in units of MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one 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 in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
