GeForce GTX 465 vs GeForce GTX 880M

Intro

The GeForce GTX 465 has core speeds of 607 MHz on the GPU, and 802 MHz on the 1024 MB of GDDR5 RAM. It features 352 SPUs along with 44 Texture Address Units and 32 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 880M, which features GPU core speed of 954 MHz, and 4096 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also features 1536 SPUs, 128 TAUs, and 32 Raster Operation Units.

GeForce GTX 465 102592 MB/sec
Difference: 25408 (25%)

Texel Rate

The GeForce GTX 880M should be much (approximately 357%) more effective at anisotropic filtering than the GeForce GTX 465. (explain)

GeForce GTX 880M 122112 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 95404 (357%)

Pixel Rate

The GeForce GTX 880M will be quite a bit (about 57%) more effective at FSAA than the GeForce GTX 465, and also will be able to handle higher resolutions more effectively. (explain)

GeForce GTX 880M 30528 Mpixels/sec
GeForce GTX 465 19424 Mpixels/sec
Difference: 11104 (57%)

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 information (measured in MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its 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 sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
