GeForce GTX 465 vs GeForce GTX 970M

Intro

The GeForce GTX 465 makes use of a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 RAM is set to run at a frequency of 802 MHz on this particular model. It features 352 SPUs as well as 44 Texture Address Units and 32 ROPs.

Compare that to the GeForce GTX 970M, which uses a 28 nm design. nVidia has set the core speed at 924 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this specific model. It features 1280 SPUs along with 80 TAUs and 48 ROPs.

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

Memory Bandwidth

As far as performance goes, the GeForce GTX 465 should in theory be a small bit better than the GeForce GTX 970M in general. (explain)

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

Texel Rate

The GeForce GTX 970M should be a lot (more or less 177%) more effective at anisotropic filtering than the GeForce GTX 465. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 970M is the winner, and very much so. (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 max amount of data (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 can be applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
