GeForce 9800 GTX vs GeForce GTX 750

Intro

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

Memory Bandwidth

As far as performance goes, the GeForce GTX 750 should in theory be 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 a lot (approximately 32%) better at AF 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 is quite a bit (approximately 51%) more effective at full screen anti-aliasing than the GeForce 9800 GTX, and also capable of handling higher screen resolutions better. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If 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 are applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video 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 Render Output Units 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 lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
