GeForce 9800 GTX+ vs GeForce GTX 750

Intro

The GeForce 9800 GTX+ makes use of a 55 nm design. nVidia has clocked the core speed at 738 MHz. The GDDR3 RAM runs at a speed of 1100 MHz on this model. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Compare that to the GeForce GTX 750, which comes with a core clock speed of 1020 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is made up 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+ 145 Watts
Difference: 90 Watts (164%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 should be a little bit faster than the GeForce 9800 GTX+ overall. (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 (approximately 45%) better at AF 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 will be much (more or less 38%) faster with regards to FSAA than the GeForce 9800 GTX+, and also should be able to handle higher screen 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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling 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 graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few 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.
