GeForce 9800 GTX vs GeForce GTX 750

Intro

The GeForce 9800 GTX features core clock speeds of 675 MHz on the GPU, and 1100 MHz on the 512 MB of GDDR3 RAM. It features 128 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 750, which features clock speeds of 1020 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 memory. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 55 Watts
GeForce 9800 GTX 140 Watts
Difference: 85 Watts (155%)

Memory Bandwidth

In theory, the GeForce GTX 750 will be 14% faster than the GeForce 9800 GTX overall, due to its higher bandwidth. (explain)

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

Texel Rate

The GeForce 9800 GTX should be quite a bit (more or less 32%) better at texture filtering than the GeForce GTX 750. (explain)

GeForce 9800 GTX 43200 Mtexels/sec
GeForce GTX 750 32640 Mtexels/sec
Difference: 10560 (32%)

Pixel Rate

The GeForce GTX 750 should be a lot (approximately 51%) more effective at FSAA than the GeForce 9800 GTX, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 750 16320 Mpixels/sec
GeForce 9800 GTX 10800 Mpixels/sec
Difference: 5520 (51%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
