GeForce GT 230 vs GeForce GTX 750

Intro

Compare all of that to the GeForce GTX 750, which features core clock speeds of 1020 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 RAM. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750		55 Watts
GeForce GT 230		65 Watts
	Difference: 10 Watts (18%)

Memory Bandwidth

In theory, the GeForce GTX 750 is 108% faster than the GeForce GT 230 overall, due to its greater bandwidth. (explain)

GeForce GTX 750		80000 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 41600 (108%)

Texel Rate

The GeForce GTX 750 is quite a bit (approximately 271%) more effective at AF than the GeForce GT 230. (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 23840 (271%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 750 is a better choice, by far. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 11920 (271%)

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 (measured in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
