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

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 650, in theory, should perform quite a bit faster than the Radeon HD 4350 overall. (explain)
Texel RateThe GeForce GTX 650 is a lot (more or less 636%) faster with regards to AF than the Radeon HD 4350. (explain)
Pixel RateThe GeForce GTX 650 should be quite a bit (about 636%) faster with regards to anti-aliasing than the Radeon HD 4350, and should be able to handle higher resolutions more effectively. (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 max amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core 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 in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
