GeForce 825M vs GeForce GT 210

Intro

The GeForce 825M features a clock speed of 850 MHz and a DDR3 memory speed of 900 MHz. It also uses a 64-bit memory bus, and uses a 28 nm design. It features 384 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210 31 Watts
GeForce 825M 33 Watts
Difference: 2 Watts (6%)

Memory Bandwidth

In theory, the GeForce 825M is 13% faster than the GeForce GT 210 overall, due to its greater data rate. (explain)

GeForce 825M 14400 MB/sec
GeForce GT 210 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The GeForce 825M is a lot (more or less 189%) faster with regards to anisotropic filtering than the GeForce GT 210. (explain)

GeForce 825M 13600 Mtexels/sec
GeForce GT 210 4712 Mtexels/sec
Difference: 8888 (189%)

Pixel Rate

The GeForce 825M should be quite a bit (more or less 189%) more effective at FSAA than the GeForce GT 210, and capable of handling higher resolutions more effectively. (explain)

GeForce 825M 6800 Mpixels/sec
GeForce GT 210 2356 Mpixels/sec
Difference: 4444 (189%)

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 largest amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
