GeForce GTX 465 vs GeForce GTX 870M

Intro

The GeForce GTX 465 has a GPU core speed of 607 MHz, and the 1024 MB of GDDR5 memory is set to run at 802 MHz through a 256-bit bus. It also is comprised of 352 Stream Processors, 44 Texture Address Units, and 32 ROPs.

Compare all of that to the GeForce GTX 870M, which comes with a core clock frequency of 941 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 192-bit memory bus, and uses a 28 nm design. It is made up of 1344 SPUs, 112 TAUs, and 24 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 870M 110 Watts
GeForce GTX 465 200 Watts
Difference: 90 Watts (82%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 465 is 7% faster than the GeForce GTX 870M overall, because of its greater bandwidth. (explain)

GeForce GTX 465 102592 MB/sec
GeForce GTX 870M 96000 MB/sec
Difference: 6592 (7%)

Texel Rate

The GeForce GTX 870M will be a lot (about 295%) better at texture filtering than the GeForce GTX 465. (explain)

GeForce GTX 870M 105392 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 78684 (295%)

Pixel Rate

The GeForce GTX 870M should be just a bit (more or less 16%) more effective at anti-aliasing than the GeForce GTX 465, and should be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 870M 22584 Mpixels/sec
GeForce GTX 465 19424 Mpixels/sec
Difference: 3160 (16%)

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 information (counted in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
