GeForce GTX 465 vs GeForce GTX 970M

Intro

The GeForce GTX 465 has a GPU clock speed of 607 MHz, and the 1024 MB of GDDR5 RAM runs at 802 MHz through a 256-bit bus. It also is made up of 352 SPUs, 44 TAUs, and 32 ROPs.

Compare those specs to the GeForce GTX 970M, which features GPU clock speed of 924 MHz, and 3072 MB of GDDR5 memory running at 1000 MHz through a 192-bit bus. It also is comprised of 1280 Stream Processors, 80 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 970M 75 Watts
GeForce GTX 465 200 Watts
Difference: 125 Watts (167%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 465 will be 7% faster than the GeForce GTX 970M in general, because of its greater bandwidth. (explain)

GeForce GTX 465 102592 MB/sec
GeForce GTX 970M 96000 MB/sec
Difference: 6592 (7%)

Texel Rate

The GeForce GTX 970M should be quite a bit (more or less 177%) more effective at AF than the GeForce GTX 465. (explain)

GeForce GTX 970M 73920 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 47212 (177%)

Pixel Rate

The GeForce GTX 970M should be much (more or less 128%) more effective at full screen anti-aliasing than the GeForce GTX 465, and also capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 970M 44352 Mpixels/sec
GeForce GTX 465 19424 Mpixels/sec
Difference: 24928 (128%)

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 (measured in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 can be processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at 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 the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes 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 memory bandwidth is, the lower the potential to reach the max fill rate.
