GeForce GTX 460 2GB vs GeForce GTX 880M

Intro

The GeForce GTX 460 2GB features a GPU core speed of 675 MHz, and the 2048 MB of GDDR5 memory runs at 900 MHz through a 256-bit bus. It also features 336 SPUs, 56 TAUs, and 32 ROPs.

Compare all of that to the GeForce GTX 880M, which comes with a GPU core clock speed of 954 MHz, and 4096 MB of GDDR5 RAM running at 1000 MHz through a 256-bit bus. It also is made up of 1536 SPUs, 128 TAUs, and 32 ROPs.

GeForce GTX 460 2GB 115200 MB/sec
Difference: 12800 (11%)

Texel Rate

The GeForce GTX 880M will be a lot (about 223%) better at AF than the GeForce GTX 460 2GB. (explain)

GeForce GTX 880M 122112 Mtexels/sec
GeForce GTX 460 2GB 37800 Mtexels/sec
Difference: 84312 (223%)

Pixel Rate

The GeForce GTX 880M is quite a bit (more or less 41%) more effective at full screen anti-aliasing than the GeForce GTX 460 2GB, and also will be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 880M 30528 Mpixels/sec
GeForce GTX 460 2GB 21600 Mpixels/sec
Difference: 8928 (41%)

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 maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total 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 processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
