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 set the core frequency at 700 MHz. The GDDR5 memory runs at a frequency of 1150 MHz on this card. It features 720(144x5) SPUs as well as 36 Texture Address Units and 16 Rasterization Operator Units.
Compare those specs to the Radeon HD 6570 (OEM) 2GB, which makes use of a 40 nm design. AMD has clocked the core frequency at 650 MHz. The GDDR5 memory works at a speed of 1000 MHz on this particular card. 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)
The Radeon HD 5750 1GB should theoretically perform a little bit faster than the Radeon HD 6570 (OEM) 2GB overall. (explain)
Texel RateThe Radeon HD 5750 1GB should be quite a bit (approximately 62%) faster with regards to texture filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe Radeon HD 5750 1GB is quite a bit (more or less 115%) faster with regards to full screen anti-aliasing than the Radeon HD 6570 (OEM) 2GB, and also will be able to handle higher screen 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 maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per 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. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
