GeForce GT 130 vs GeForce GTX 750

Intro

Compare those specs to the GeForce GTX 750, which comes with a core clock frequency of 1020 MHz and a GDDR5 memory frequency of 1250 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is made up of 512 SPUs, 32 Texture Address Units, 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

As far as performance goes, the GeForce GTX 750 should theoretically be much superior to 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 (more or less 172%) more effective at texture filtering 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 lots of anti-aliasing 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: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total 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 in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
