GeForce 940M vs GeForce GT 210

Intro

The GeForce 940M comes with a GPU core speed of 1072 MHz, and the 2048 MB of DDR3 memory runs at 1000 MHz through a 64-bit bus. It also is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Compare those specs to the GeForce GT 210, which uses a 40 nm design. nVidia has set the core frequency at 589 MHz. The DDR3 RAM works at a speed of 800 MHz on this model. It features 16 SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 940M should in theory be much faster than the GeForce GT 210 overall. (explain)

GeForce 940M 16000 MB/sec
GeForce GT 210 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The GeForce 940M will be a lot (approximately 446%) better at anisotropic filtering than the GeForce GT 210. (explain)

GeForce 940M 25728 Mtexels/sec
GeForce GT 210 4712 Mtexels/sec
Difference: 21016 (446%)

Pixel Rate

The GeForce 940M should be quite a bit (about 264%) better at anti-aliasing than the GeForce GT 210, and also capable of handling higher resolutions while still performing well. (explain)

GeForce 940M 8576 Mpixels/sec
GeForce GT 210 2356 Mpixels/sec
Difference: 6220 (264%)

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 (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be 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 better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). 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 ability to get to the maximum fill rate.
