GeForce GTS 150 vs GeForce GTX 750

Intro

Compare that to the GeForce GTX 750, which makes use of a 28 nm design. nVidia has set the core frequency at 1020 MHz. The GDDR5 RAM is set to run at a speed of 1250 MHz on this particular model. It features 512 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750		55 Watts
GeForce GTS 150		141 Watts
	Difference: 86 Watts (156%)

Memory Bandwidth

In theory, the GeForce GTX 750 should be quite a bit faster than the GeForce GTS 150 overall. (explain)

GeForce GTX 750		80000 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 48000 (150%)

Texel Rate

The GeForce GTS 150 is quite a bit (about 45%) more effective at texture filtering than the GeForce GTX 750. (explain)

GeForce GTS 150		47360 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 14720 (45%)

Pixel Rate

If running with a high screen resolution 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 150		11840 Mpixels/sec
	Difference: 4480 (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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
