GeForce 940M vs GeForce GTX 295

Intro

Compare all of that to the GeForce GTX 295, which features clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 memory. It features 240 SPUs as well as 80 TAUs and 28 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 295 should in theory be much faster than the GeForce 940M in general. (explain)

GeForce GTX 295		223776 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 207776 (1299%)

Texel Rate

The GeForce GTX 295 will be much (about 258%) more effective at anisotropic filtering than the GeForce 940M. (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 66432 (258%)

Pixel Rate

The GeForce GTX 295 will be much (approximately 276%) more effective at full screen anti-aliasing than the GeForce 940M, and also should be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 23680 (276%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
