GeForce 940M vs GeForce GTS 250 1GB

Intro

The GeForce 940M comes with a core clock speed of 1072 MHz and a DDR3 memory frequency of 1000 MHz. It also features a 64-bit bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Compare those specifications to the GeForce GTS 250 1GB, which uses a 65/55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 RAM runs at a frequency of 1100 MHz on this card. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTS 250 1GB should be 340% faster than the GeForce 940M overall, due to its higher data rate. (explain)

GeForce GTS 250 1GB 70400 MB/sec
GeForce 940M 16000 MB/sec
Difference: 54400 (340%)

Texel Rate

The GeForce GTS 250 1GB will be a lot (more or less 84%) better at AF than the GeForce 940M. (explain)

GeForce GTS 250 1GB 47232 Mtexels/sec
GeForce 940M 25728 Mtexels/sec
Difference: 21504 (84%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTS 250 1GB is superior to the GeForce 940M, by a large margin. (explain)

GeForce GTS 250 1GB 11808 Mpixels/sec
GeForce 940M 8576 Mpixels/sec
Difference: 3232 (38%)

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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour 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 is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
