Compare any two graphics cards:
GeForce GT 240 GDDR5 vs Radeon HD 4670 512MB
IntroThe GeForce GT 240 GDDR5 has a clock speed of 550 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is comprised of 96 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.
Compare all of that to the Radeon HD 4670 512MB, which makes use of a 55 nm design. ATi has set the core frequency at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 memory works at a speed of 1000 MHz on this specific model. It features 320(64x5) SPUs as well as 32 TAUs 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.
Theoretically speaking, the GeForce GT 240 GDDR5 will be 70% quicker than the Radeon HD 4670 512MB in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 4670 512MB will be a lot (approximately 36%) faster with regards to texture filtering than the GeForce GT 240 GDDR5. (explain)
Pixel RateThe Radeon HD 4670 512MB should be a lot (approximately 36%) better at AA than the GeForce GT 240 GDDR5, and also should be able to handle higher resolutions while still performing well. (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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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 reach the max fill rate.
