GeForce GTX 275 vs GeForce GTX 880M

Intro

The GeForce GTX 275 comes with a GPU core clock speed of 633 MHz, and the 896 MB of GDDR3 memory runs at 1134 MHz through a 448-bit bus. It also features 240 SPUs, 80 TAUs, and 28 ROPs.

Compare that to the GeForce GTX 880M, which uses a 28 nm design. nVidia has clocked the core frequency at 954 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this specific card. It features 1536 SPUs as well as 128 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 880M 130 Watts
GeForce GTX 275 219 Watts
Difference: 89 Watts (68%)

Memory Bandwidth

The GeForce GTX 880M, in theory, should be just a bit faster than the GeForce GTX 275 in general. (explain)

GeForce GTX 880M 128000 MB/sec
GeForce GTX 275 127008 MB/sec
Difference: 992 (1%)

Texel Rate

The GeForce GTX 880M should be quite a bit (approximately 141%) more effective at AF than the GeForce GTX 275. (explain)

GeForce GTX 880M 122112 Mtexels/sec
GeForce GTX 275 50640 Mtexels/sec
Difference: 71472 (141%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 880M is a better choice, by far. (explain)

GeForce GTX 880M 30528 Mpixels/sec
GeForce GTX 275 17724 Mpixels/sec
Difference: 12804 (72%)

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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

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