Compare any two graphics cards:
GeForce GT 210 vs Radeon HD 4550 512MB
IntroThe GeForce GT 210 has core clock speeds of 589 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 memory. It features 16 SPUs as well as 8 TAUs and 4 Rasterization Operator Units.
Compare those specifications to the Radeon HD 4550 512MB, which comes with a core clock speed of 600 MHz and a GDDR3 memory frequency of 800 MHz. It also uses a 64-bit bus, and makes use of a 55 nm design. It is made up of 80(16x5) SPUs, 8 Texture Address Units, and 4 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Both cards have exactly the same bandwidth, so in theory they should have the same performance. (explain)
Texel RateThe Radeon HD 4550 512MB should be just a bit (about 2%) better at texture filtering than the GeForce GT 210. (explain)
Pixel RateThe Radeon HD 4550 512MB will be just a bit (more or less 2%) faster with regards to AA than the GeForce GT 210, and also will be capable of handling 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 information (measured in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
