Compare any two graphics cards:
GeForce GT 240 GDDR5 vs Radeon HD 4670 512MB
IntroThe GeForce GT 240 GDDR5 uses a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 RAM is set to run at a frequency of 850 MHz on this specific card. It features 96 SPUs as well as 32 TAUs and 8 ROPs.
Compare those specifications to the Radeon HD 4670 512MB, which comes with core clock speeds of 750 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR4/GDDR3/DDR3/DDR2 memory. It features 320(64x5) SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Radeon HD 4670 512MB wins
(Based entirely on the benchmarks listed above)
When combining all game benchmark scores on this page together, the Radeon HD 4670 512MB wins overall, by 9 FPS. Please note that we do not have the results of every benchmark ever done for these cards, so the results may differ wildly in different games.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
The GeForce GT 240 GDDR5, in theory, should be quite a bit faster than the Radeon HD 4670 512MB in general. (explain)
Texel RateThe Radeon HD 4670 512MB is much (approximately 36%) faster with regards to AF than the GeForce GT 240 GDDR5. (explain)
Pixel RateThe Radeon HD 4670 512MB will be a lot (more or less 36%) better at anti-aliasing than the GeForce GT 240 GDDR5, and also able to handle higher screen resolutions without slowing down too much. (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 information (counted in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of 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 amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
