Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon HD 4650 1GB
IntroThe GeForce GTS 250 1GB features a core clock speed of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also makes use of a 256-bit memory bus, and uses a 65/55 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.Compare those specifications to the Radeon HD 4650 1GB, which features GPU core speed of 600 MHz, and 1024 MB of GDDR3 RAM set to run at 700 MHz through a 128-bit bus. It also is made up of 320(64x5) SPUs, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTS 250 1GB should theoretically be a lot better than the Radeon HD 4650 1GB overall. (explain)
Texel RateThe GeForce GTS 250 1GB will be much (approximately 146%) better at AF than the Radeon HD 4650 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTS 250 1GB 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: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video 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 the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
