Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 4770
IntroThe GeForce GTS 450 1GB comes with a core clock speed of 783 MHz and a GDDR5 memory frequency of 902 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It features 192 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.Compare that to the Radeon HD 4770, which uses a 40 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 RAM works at a frequency of 800 MHz on this particular model. It features 640(128x5) SPUs along with 32 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTS 450 1GB should in theory be a small bit better than the Radeon HD 4770 overall. (explain)
Texel RateThe GeForce GTS 450 1GB will be a bit (approximately 4%) more effective at texture filtering than the Radeon HD 4770. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTS 450 1GB is a better choice, but not by far. (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 (measured in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core 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 most pixels that the graphics chip can possibly record to its local memory in one 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
