VS

GeForce GTX 460 (OEM) vs GeForce GTX 880M

Intro

The GeForce GTX 460 (OEM) has a GPU core speed of 650 MHz, and the 1024 MB of GDDR5 RAM is set to run at 850 MHz through a 256-bit bus. It also features 336 SPUs, 56 TAUs, and 32 Raster Operation Units.

Compare that to the GeForce GTX 880M, which makes use of a 28 nm design. nVidia has set the core frequency at 954 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this particular card. It features 1536 SPUs as well as 128 TAUs and 32 ROPs.

The GeForce GTX 880M is quite a bit (about 235%) better at texture filtering than the GeForce GTX 460 (OEM). (explain)

GeForce GTX 880M 122112 Mtexels/sec
GeForce GTX 460 (OEM) 36400 Mtexels/sec
Difference: 85712 (235%)

Pixel Rate

The GeForce GTX 880M is much (approximately 47%) faster with regards to anti-aliasing than the GeForce GTX 460 (OEM), and also capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 880M 30528 Mpixels/sec
GeForce GTX 460 (OEM) 20800 Mpixels/sec
Difference: 9728 (47%)

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 MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one 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 the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
