GeForce GTS 250 1GB 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 memory. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750		55 Watts
GeForce GTS 250 1GB		145 Watts
	Difference: 90 Watts (164%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 should perform a little bit faster than the GeForce GTS 250 1GB overall. (explain)

GeForce GTX 750		80000 MB/sec
GeForce GTS 250 1GB		70400 MB/sec
	Difference: 9600 (14%)

Texel Rate

The GeForce GTS 250 1GB is quite a bit (approximately 45%) faster with regards to texture filtering than the GeForce GTX 750. (explain)

GeForce GTS 250 1GB		47232 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 14592 (45%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 750 is the winner, and very much so. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce GTS 250 1GB		11808 Mpixels/sec
	Difference: 4512 (38%)

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 (in units of MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
