Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon HD 5770
IntroThe GeForce GTS 250 1GB uses a 65/55 nm design. nVidia has set the core speed at 738 MHz. The GDDR3 RAM runs at a speed of 1100 MHz on this particular model. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.Compare all of that to the Radeon HD 5770, which comes with clock speeds of 850 MHz on the GPU, and 1200 MHz on the 1024 MB of GDDR5 RAM. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 5770 should be 9% quicker than the GeForce GTS 250 1GB overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTS 250 1GB is a lot (about 39%) better at anisotropic filtering than the Radeon HD 5770. (explain)
Pixel RateThe Radeon HD 5770 will be a little bit (approximately 15%) faster with regards to AA than the GeForce GTS 250 1GB, and also will be capable of handling higher screen 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 Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, 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 number of pixels the video card could possibly write to its local memory per 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 - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
