GeForce 940M vs GeForce GT 210

Intro

The GeForce 940M makes use of a 28 nm design. nVidia has set the core speed at 1072 MHz. The DDR3 memory runs at a speed of 1000 MHz on this particular model. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Compare those specifications to the GeForce GT 210, which comes with clock speeds of 589 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 memory. It features 16 SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 940M should be a lot 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 should be a lot (about 446%) more effective at texture 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 a lot (approximately 264%) better at AA than the GeForce GT 210, and also capable of handling higher screen resolutions without losing too much performance. (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: Bandwidth is the max amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
