GeForce GTX 275 vs GeForce GTX 960M

Intro

Compare all that to the GeForce GTX 960M, which has a clock speed of 1096 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 960M		65 Watts
GeForce GTX 275		219 Watts
	Difference: 154 Watts (237%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 275 should be 98% faster than the GeForce GTX 960M in general, because of its higher bandwidth. (explain)

GeForce GTX 275		127008 MB/sec
GeForce GTX 960M		64000 MB/sec
	Difference: 63008 (98%)

Texel Rate

The GeForce GTX 275 is a little bit (more or less 16%) more effective at anisotropic filtering than the GeForce GTX 960M. (explain)

GeForce GTX 275		50640 Mtexels/sec
GeForce GTX 960M		43840 Mtexels/sec
	Difference: 6800 (16%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 275 is a better choice, though only just barely. (explain)

GeForce GTX 275		17724 Mpixels/sec
GeForce GTX 960M		17536 Mpixels/sec
	Difference: 188 (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 (counted in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
