GeForce GTX 275 vs GeForce GTX 960M

Intro

The GeForce GTX 275 features a core clock frequency of 633 MHz and a GDDR3 memory frequency of 1134 MHz. It also features a 448-bit bus, and uses a 55 nm design. It is comprised of 240 SPUs, 80 TAUs, and 28 Raster Operation Units.

Compare all of that to the GeForce GTX 960M, which features GPU core speed of 1096 MHz, and 2048 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

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

In theory, the GeForce GTX 275 should perform much faster than the GeForce GTX 960M overall. (explain)

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

Texel Rate

The GeForce GTX 275 will be a small bit (about 16%) more effective at AF 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 lots of anti-aliasing is important to you, then the GeForce GTX 275 is a better choice, not by a very large margin though. (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.

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen 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 amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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