Compare any two graphics cards:
GeForce GTX 650 vs Radeon HD 6570 (OEM) 1GB
IntroThe GeForce GTX 650 has a clock speed of 1058 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is comprised of 384 SPUs, 32 TAUs, and 16 ROPs.
Compare that to the Radeon HD 6570 (OEM) 1GB, which features core speeds of 650 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 RAM. It features 480 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 650 will be 178% faster than the Radeon HD 6570 (OEM) 1GB in general, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 650 will be quite a bit (more or less 117%) more effective at AF than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 650 is superior to the Radeon HD 6570 (OEM) 1GB, and very much so. (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 max amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 are applied in one second. This number is worked out by multiplying the total number of texture units by the core clock 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 most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
