VS

GeForce GT 210 vs Radeon HD 7770

Intro

The GeForce GT 210 features core speeds of 589 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 RAM. It features 16 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.

Compare that to the Radeon HD 7770, which has a GPU core clock speed of 1000 MHz, and 1024 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210 31 Watts
Radeon HD 7770 80 Watts
Difference: 49 Watts (158%)

Memory Bandwidth

In theory, the Radeon HD 7770 will be 463% faster than the GeForce GT 210 in general, due to its higher data rate. (explain)

Radeon HD 7770 72000 MB/sec
GeForce GT 210 12800 MB/sec
Difference: 59200 (463%)

Texel Rate

The Radeon HD 7770 will be quite a bit (about 749%) more effective at anisotropic filtering than the GeForce GT 210. (explain)

Radeon HD 7770 40000 Mtexels/sec
GeForce GT 210 4712 Mtexels/sec
Difference: 35288 (749%)

Pixel Rate

The Radeon HD 7770 will be much (about 579%) faster with regards to FSAA than the GeForce GT 210, and should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon HD 7770 16000 Mpixels/sec
GeForce GT 210 2356 Mpixels/sec
Difference: 13644 (579%)

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 information (counted in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 are applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of 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.
