Compare any two graphics cards:
GeForce GT 210 vs Radeon HD 5450
IntroThe GeForce GT 210 has a GPU core clock speed of 589 MHz, and the 512 MB of DDR3 RAM runs at 800 MHz through a 64-bit bus. It also is comprised of 16 Stream Processors, 8 Texture Address Units, and 4 ROPs.
Compare those specifications to the Radeon HD 5450, which comes with GPU core speed of 650 MHz, and 512 MB of DDR3 RAM running at 800 MHz through a 64-bit bus. It also features 80(16x5) SPUs, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Both cards have the exact same bandwidth, so in theory they should have the same performance. (explain)
Texel RateThe Radeon HD 5450 should be just a bit (about 10%) faster with regards to anisotropic filtering than the GeForce GT 210. (explain)
Pixel RateThe Radeon HD 5450 will be a small bit (about 10%) better at full screen anti-aliasing than the GeForce GT 210, and also will be able to handle higher screen resolutions better. (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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should 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 AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
