Compare any two graphics cards:
GeForce GTX 285 1GB vs Radeon HD 4670 512MB
IntroThe GeForce GTX 285 1GB has a GPU core speed of 648 MHz, and the 1024 MB of GDDR3 RAM runs at 1242 MHz through a 512-bit bus. It also features 240 SPUs, 80 Texture Address Units, and 32 Raster Operation Units.
Compare all that to the Radeon HD 4670 512MB, which comes with a core clock speed of 750 MHz and a GDDR4/GDDR3/DDR3/DDR2 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and makes use of a 55 nm design. It features 320(64x5) SPUs, 32 Texture Address Units, and 8 Raster Operation Units.

GeForce GTX 285 1GB wins
(Based entirely on the benchmarks listed above)
When combining all game benchmark scores on this page together, the GeForce GTX 285 1GB wins overall, by 274 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 Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 285 1GB should perform a lot faster than the Radeon HD 4670 512MB overall. (explain)
Texel RateThe GeForce GTX 285 1GB should be much (approximately 116%) more effective at AF than the Radeon HD 4670 512MB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 285 1GB is a better choice, and very much so. (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 data (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the 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 number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
