Compare any two graphics cards:
Radeon HD 5850 vs Radeon HD 6570 (OEM) 1GB
IntroThe Radeon HD 5850 uses a 40 nm design. AMD has set the core speed at 725 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this particular model. It features 1440(288x5) SPUs as well as 72 Texture Address Units and 32 ROPs.
Compare all of that to the Radeon HD 6570 (OEM) 1GB, which has core speeds of 650 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 RAM. It features 480 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon HD 5850 should perform much faster than the Radeon HD 6570 (OEM) 1GB overall. (explain)
Texel RateThe Radeon HD 5850 should be a lot (more or less 235%) faster with regards to texture filtering than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateThe Radeon HD 5850 should be much (approximately 346%) faster with regards to anti-aliasing than the Radeon HD 6570 (OEM) 1GB, and capable of handling higher screen 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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 can be processed per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
