Compare any two graphics cards:
GeForce GT 210 vs Radeon HD 4650 1GB
IntroThe GeForce GT 210 has a core clock speed of 589 MHz and a DDR3 memory frequency of 800 MHz. It also uses a 64-bit memory bus, and uses a 40 nm design. It is made up of 16 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.
Compare those specifications to the Radeon HD 4650 1GB, which makes use of a 55 nm design. AMD has clocked the core speed at 600 MHz. The GDDR3 RAM works at a frequency of 700 MHz on this particular card. It features 320(64x5) SPUs along with 32 TAUs and 8 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Radeon HD 4650 1GB should theoretically be a lot better than the GeForce GT 210 overall. (explain)
Texel RateThe Radeon HD 4650 1GB is quite a bit (approximately 307%) more effective at anisotropic filtering than the GeForce GT 210. (explain)
Pixel RateThe Radeon HD 4650 1GB will be a lot (about 104%) faster with regards to anti-aliasing than the GeForce GT 210, and capable of handling higher screen resolutions without losing too much performance. (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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better 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 a second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
