GeForce 930M vs GeForce GTX 465

Intro

Compare all of that to the GeForce GTX 465, which comes with a clock frequency of 607 MHz and a GDDR5 memory speed of 802 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It features 352 SPUs, 44 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 465 should theoretically be much superior to the GeForce 930M overall. (explain)

GeForce GTX 465		102592 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 88192 (612%)

Texel Rate

The GeForce GTX 465 will be just a bit (about 20%) faster with regards to texture filtering than the GeForce 930M. (explain)

GeForce GTX 465		26708 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 4436 (20%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 465 is the winner, by far. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 12000 (162%)

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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high 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 number of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
