GeForce 940M vs GeForce GTX 465

Intro

Compare those specs to the GeForce GTX 465, which has GPU clock speed of 607 MHz, and 1024 MB of GDDR5 RAM set to run at 802 MHz through a 256-bit bus. It also is comprised of 352 SPUs, 44 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 465 should perform quite a bit faster than the GeForce 940M in general. (explain)

GeForce GTX 465		102592 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 86592 (541%)

Texel Rate

The GeForce GTX 465 should be just a bit (approximately 4%) faster with regards to AF than the GeForce 940M. (explain)

GeForce GTX 465		26708 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 980 (4%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 465 is superior to the GeForce 940M, by far. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 10848 (126%)

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 maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
