Compare any two graphics cards:
GeForce GT 210 vs Radeon HD 4650 1GB
IntroThe GeForce GT 210 comes with a core clock speed of 589 MHz and a DDR3 memory frequency of 800 MHz. It also features a 64-bit memory bus, and makes use of a 40 nm design. It is comprised of 16 SPUs, 8 Texture Address Units, and 4 ROPs.
Compare those specs to the Radeon HD 4650 1GB, which comes with GPU clock speed of 600 MHz, and 1024 MB of GDDR3 memory set to run at 700 MHz through a 128-bit bus. It also is comprised of 320(64x5) Stream Processors, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 4650 1GB, in theory, should be a lot faster than the GeForce GT 210 in general. (explain)
Texel RateThe Radeon HD 4650 1GB is much (about 307%) faster with regards to anisotropic filtering than the GeForce GT 210. (explain)
Pixel RateThe Radeon HD 4650 1GB will be a lot (approximately 104%) more effective at full screen anti-aliasing than the GeForce GT 210, and also able to handle higher resolutions without slowing down too much. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units of the card by the core clock 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 most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units 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 ability to reach the maximum fill rate.
