Compare any two graphics cards:
GeForce GTX 650 vs Radeon HD 4350
IntroThe GeForce GTX 650 uses a 28 nm design. nVidia has clocked the core frequency at 1058 MHz. The GDDR5 RAM is set to run at a frequency of 1250 MHz on this particular model. It features 384 SPUs along with 32 TAUs and 16 Rasterization Operator Units.
Compare that to the Radeon HD 4350, which comes with core clock speeds of 575 MHz on the GPU, and 500 MHz on the 512 MB of DDR2 memory. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 650 should theoretically be much faster than the Radeon HD 4350 overall. (explain)
Texel RateThe GeForce GTX 650 is a lot (approximately 636%) more effective at AF than the Radeon HD 4350. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 650 is a better choice, by a large margin. (explain)
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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
