Compare any two graphics cards:
Radeon HD 6570 (OEM) 2GB vs Radeon R7 240
IntroThe Radeon HD 6570 (OEM) 2GB uses a 40 nm design. ATi has clocked the core frequency at 650 MHz. The GDDR5 memory works at a speed of 1000 MHz on this particular model. It features 480 SPUs as well as 24 TAUs and 8 ROPs.
Compare those specifications to the Radeon R7 240, which comes with a core clock frequency of 730 MHz and a DDR3 memory frequency of 900 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It features 320 SPUs, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 6570 (OEM) 2GB should theoretically perform quite a bit faster than the Radeon R7 240 overall. (explain)
Texel RateThe Radeon HD 6570 (OEM) 2GB is just a bit (more or less 7%) better at texture filtering than the Radeon R7 240. (explain)
Pixel RateThe Radeon R7 240 is a bit (more or less 12%) better at full screen anti-aliasing than the Radeon HD 6570 (OEM) 2GB, and capable of handling 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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record 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 - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
