GeForce GTX 465 vs GeForce GTX 870M

Intro

The GeForce GTX 465 uses a 40 nm design. nVidia has clocked the core frequency at 607 MHz. The GDDR5 RAM works at a frequency of 802 MHz on this specific model. It features 352 SPUs along with 44 TAUs and 32 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 870M, which features GPU clock speed of 941 MHz, and 3072 MB of GDDR5 RAM running at 1000 MHz through a 192-bit bus. It also features 1344 SPUs, 112 TAUs, and 24 Raster Operation Units.

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce GTX 465 should perform a little bit faster than the GeForce GTX 870M overall. (explain)

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

Texel Rate

The GeForce GTX 870M is a lot (more or less 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

If running with high levels of AA is important to you, then the GeForce GTX 870M is superior to the GeForce GTX 465, though not by far. (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: Bandwidth is the maximum amount of data (in units of MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
