VS

GeForce 9400 GT 256MB vs GeForce GT 210

Intro

The GeForce 9400 GT 256MB features a GPU core speed of 550 MHz, and the 256 MB of GDDR2 RAM runs at 400 MHz through a 128-bit bus. It also is comprised of 16 Stream Processors, 8 TAUs, and 4 ROPs.

Compare that to the GeForce GT 210, which has a GPU core clock speed of 589 MHz, and 512 MB of DDR3 RAM running at 800 MHz through a 64-bit bus. It also features 16 SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210 31 Watts
GeForce 9400 GT 256MB 50 Watts
Difference: 19 Watts (61%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The GeForce GT 210 will be just a bit (more or less 7%) faster with regards to anisotropic filtering than the GeForce 9400 GT 256MB. (explain)

GeForce GT 210 4712 Mtexels/sec
GeForce 9400 GT 256MB 4400 Mtexels/sec
Difference: 312 (7%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GT 210 is the winner, though not by far. (explain)

GeForce GT 210 2356 Mpixels/sec
GeForce 9400 GT 256MB 2200 Mpixels/sec
Difference: 156 (7%)

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 maximum amount of information (measured in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics 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 write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
