Compare any two graphics cards:
Radeon HD 5850 vs Radeon R7 M360
IntroThe Radeon HD 5850 comes with core clock speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 1440(288x5) SPUs along with 72 TAUs and 32 Rasterization Operator Units.
Compare those specs to the Radeon R7 M360, which comes with a core clock speed of 1125 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 64-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 ROPs.
Power Usage and Theoretical Benchmarks
In theory, the Radeon HD 5850 is 700% faster than the Radeon R7 M360 in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 5850 should be quite a bit (about 93%) faster with regards to AF than the Radeon R7 M360. (explain)
Pixel RateThe Radeon HD 5850 is a lot (about 158%) better at FSAA than the Radeon R7 M360, and will be able to handle higher resolutions without losing too much performance. (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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core 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 applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
