Compare any two graphics cards:
Radeon R5 M330 vs Radeon R7 370 2G
IntroThe Radeon R5 M330 comes with a clock speed of 1030 MHz and a DDR3 memory speed of 900 MHz. It also uses a 64-bit memory bus, and makes use of a 28 nm design. It features 320 SPUs, 20 Texture Address Units, and 8 Raster Operation Units.
Compare those specifications to the Radeon R7 370 2G, which comes with core speeds of 975 MHz on the GPU, and 1400 MHz on the 2048 MB of GDDR5 RAM. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
The Radeon R7 370 2G should theoretically be a lot faster than the Radeon R5 M330 in general. (explain)
Texel RateThe Radeon R7 370 2G is much (approximately 203%) faster with regards to AF than the Radeon R5 M330. (explain)
Pixel RateThe Radeon R7 370 2G will be a lot (approximately 279%) more effective at FSAA than the Radeon R5 M330, and also capable of handling 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 max amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 can be applied per second. This figure 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 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 in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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 reach the max fill rate.
