GeForce 9800 GTX vs GeForce GTX 750

Intro

The GeForce 9800 GTX comes with a GPU clock speed of 675 MHz, and the 512 MB of GDDR3 RAM is set to run at 1100 MHz through a 256-bit bus. It also is comprised of 128 SPUs, 64 TAUs, and 16 ROPs.

Compare those specifications to the GeForce GTX 750, which features a clock speed of 1020 MHz and a GDDR5 memory speed of 1250 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 512 SPUs, 32 Texture Address Units, and 16 ROPs.

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

The GeForce GTX 750 should theoretically be a small bit faster than 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 should be a lot (more or less 32%) faster with regards to AF than the GeForce GTX 750. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 750 is a better choice, by far. (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 data (in units of MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
