GeForce GT 210 vs Radeon HD 7770

Intro

The GeForce GT 210 uses a 40 nm design. nVidia has set the core frequency at 589 MHz. The DDR3 memory runs at a frequency of 800 MHz on this specific card. It features 16 SPUs as well as 8 TAUs and 4 ROPs.

Compare those specs to the Radeon HD 7770, which comes with core clock speeds of 1000 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 memory. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

GeForce GT 210 4712 Mtexels/sec
Difference: 35288 (749%)

Pixel Rate

The Radeon HD 7770 should be a lot (more or less 579%) better at FSAA than the GeForce GT 210, and should be capable of handling higher resolutions more effectively. (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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
