GeForce GTX 275 vs GeForce GTX 980M

Intro

The GeForce GTX 275 uses a 55 nm design. nVidia has set the core speed at 633 MHz. The GDDR3 memory works at a speed of 1134 MHz on this particular card. It features 240 SPUs as well as 80 TAUs and 28 Rasterization Operator Units.

Compare that to the GeForce GTX 980M, which features a GPU core clock speed of 1038 MHz, and 4096 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also is made up of 1536 Stream Processors, 96 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 980M 100 Watts
GeForce GTX 275 219 Watts
Difference: 119 Watts (119%)

Memory Bandwidth

The GeForce GTX 980M should theoretically be a little bit faster than the GeForce GTX 275 in general. (explain)

GeForce GTX 980M 128000 MB/sec
GeForce GTX 275 127008 MB/sec
Difference: 992 (1%)

Texel Rate

The GeForce GTX 980M should be a lot (more or less 97%) more effective at anisotropic filtering than the GeForce GTX 275. (explain)

GeForce GTX 980M 99648 Mtexels/sec
GeForce GTX 275 50640 Mtexels/sec
Difference: 49008 (97%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 980M is a better choice, and very much so. (explain)

GeForce GTX 980M 66432 Mpixels/sec
GeForce GTX 275 17724 Mpixels/sec
Difference: 48708 (275%)

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 max amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's 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 rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
