Compare any two graphics cards:
Radeon HD 7750 vs Radeon R7 240
IntroThe Radeon HD 7750 makes use of a 28 nm design. ATi has set the core frequency at 800 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this card. It features 512 SPUs as well as 32 Texture Address Units and 16 ROPs.
Compare all of that to the Radeon R7 240, which makes use of a 28 nm design. ATi has set the core frequency at 730 MHz. The DDR3 RAM is set to run at a speed of 900 MHz on this specific model. It features 320 SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon HD 7750 should in theory be much better than the Radeon R7 240 in general. (explain)
Texel RateThe Radeon HD 7750 will be much (approximately 75%) more effective at anisotropic filtering than the Radeon R7 240. (explain)
Pixel RateThe Radeon HD 7750 should be quite a bit (about 119%) more effective at anti-aliasing than the Radeon R7 240, and should be capable of handling higher resolutions while still performing well. (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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video 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 amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
