Compare any two graphics cards:
GeForce GTX 460 (OEM) vs Radeon HD 4870 2GB
IntroThe GeForce GTX 460 (OEM) uses a 40 nm design. nVidia has set the core frequency at 650 MHz. The GDDR5 memory is set to run at a speed of 850 MHz on this card. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.Compare all that to the Radeon HD 4870 2GB, which features GPU core speed of 750 MHz, and 2048 MB of GDDR5 RAM set to run at 900 MHz through a 256-bit bus. It also is comprised of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthPerformance-wise, the Radeon HD 4870 2GB should in theory be a bit better than the GeForce GTX 460 (OEM) in general. (explain)
Texel RateThe GeForce GTX 460 (OEM) will be quite a bit (approximately 21%) more effective at AF than the Radeon HD 4870 2GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 460 (OEM) 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better 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 maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
