Compare any two graphics cards:
GeForce GTX 460 vs Radeon R9 M365X
IntroThe GeForce GTX 460 has a GPU clock speed of 675 MHz, and the 768 MB of GDDR5 memory runs at 900 MHz through a 192-bit bus. It also is comprised of 336 SPUs, 56 TAUs, and 24 ROPs.
Compare those specs to the Radeon R9 M365X, which features core clock speeds of 925 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
The GeForce GTX 460, in theory, should be a little bit faster than the Radeon R9 M365X in general. (explain)
Texel RateThe GeForce GTX 460 is a bit (about 2%) faster with regards to texture filtering than the Radeon R9 M365X. (explain)
Pixel RateThe GeForce GTX 460 should be a little bit (about 9%) faster with regards to AA than the Radeon R9 M365X, and should be capable of handling higher 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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 are processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, 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 that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
