GeForce GTX 260 Core 216 vs GeForce GTX 750 Ti

Intro

Compare all that to the GeForce GTX 750 Ti, which makes use of a 28 nm design. nVidia has clocked the core speed at 1020 MHz. The GDDR5 memory is set to run at a speed of 1350 MHz on this model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
GeForce GTX 260 Core 216		202 Watts
	Difference: 142 Watts (237%)

Memory Bandwidth

In theory, the GeForce GTX 260 Core 216 will be 30% quicker than the GeForce GTX 750 Ti in general, because of its greater data rate. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 25488 (30%)

Texel Rate

The GeForce GTX 260 Core 216 is a little bit (approximately 2%) more effective at AF than the GeForce GTX 750 Ti. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 672 (2%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 750 Ti is a better choice, though not by far. (explain)

GeForce GTX 750 Ti		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 maximum amount of information (counted in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher 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 maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
