GeForce 9800 GTX+ vs GeForce GTX 750

Intro

The GeForce 9800 GTX+ features a core clock frequency of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also features a 256-bit bus, and uses a 55 nm design. It is comprised of 128 SPUs, 64 TAUs, and 16 ROPs.

Compare all of that to the GeForce GTX 750, which comes with a core clock frequency of 1020 MHz and a GDDR5 memory speed of 1250 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It features 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

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

Texel Rate

The GeForce 9800 GTX+ should be quite a bit (more or less 45%) faster with regards to texture filtering than the GeForce GTX 750. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 750 is superior to the GeForce 9800 GTX+, and very much so. (explain)

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred past the external memory interface in a second. It's 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 DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. 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 also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
