GeForce GT 130 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 features a 128-bit bus, and uses a 28 nm design. It is made up of 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750		55 Watts
GeForce GT 130		75 Watts
	Difference: 20 Watts (36%)

Memory Bandwidth

The GeForce GTX 750 should in theory be much faster than the GeForce GT 130 overall. (explain)

GeForce GTX 750		80000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 68000 (567%)

Texel Rate

The GeForce GTX 750 should be much (approximately 172%) faster with regards to AF than the GeForce GT 130. (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 20640 (172%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 750 is superior to the GeForce GT 130, and very much so. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 8320 (104%)

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 largest amount of data (counted in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 applied per second. This number is calculated 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 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 maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
