Compare any two graphics cards:
Radeon HD 5750 1GB vs Radeon HD 6570 (OEM) 2GB
IntroThe Radeon HD 5750 1GB makes use of a 40 nm design. AMD has clocked the core frequency at 700 MHz. The GDDR5 RAM is set to run at a speed of 1150 MHz on this model. It features 720(144x5) SPUs along with 36 TAUs and 16 ROPs.
Compare those specifications to the Radeon HD 6570 (OEM) 2GB, which features GPU core speed of 650 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is comprised of 480 Stream Processors, 24 TAUs, and 8 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Radeon HD 5750 1GB should be just a bit faster than the Radeon HD 6570 (OEM) 2GB in general. (explain)
Texel RateThe Radeon HD 5750 1GB will be a lot (approximately 62%) better at AF than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe Radeon HD 5750 1GB is quite a bit (about 115%) better at full screen anti-aliasing than the Radeon HD 6570 (OEM) 2GB, and should be capable of handling higher resolutions more effectively. (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 max amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
