GeForce GTX 260 Core 216 vs GeForce GTX 750

Intro

Compare all of 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 memory is set to run at a speed of 1250 MHz on this particular card. 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 GTX 260 Core 216		202 Watts
	Difference: 147 Watts (267%)

Memory Bandwidth

The GeForce GTX 260 Core 216 should in theory be a lot faster than the GeForce GTX 750 overall. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
GeForce GTX 750		80000 MB/sec
	Difference: 31888 (40%)

Texel Rate

The GeForce GTX 260 Core 216 is a lot (more or less 27%) better at AF than the GeForce GTX 750. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 8832 (27%)

Pixel Rate

The GeForce GTX 750 should be just a bit (more or less 1%) more effective at full screen anti-aliasing than the GeForce GTX 260 Core 216, and also will be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 192 (1%)

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

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
