Compare any two graphics cards:
Radeon R7 M260X vs Radeon R9 M375X
IntroThe Radeon R7 M260X makes use of a 28 nm design. AMD has set the core frequency at 825 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this specific card. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.
Compare those specs to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The GDDR5 RAM runs at a frequency of 1125 MHz on this particular card. It features 640 SPUs along with 40 TAUs and 16 ROPs.
Power Usage and Theoretical Benchmarks
In theory, the Radeon R9 M375X should be just a bit faster than the Radeon R7 M260X overall. (explain)
Texel RateThe Radeon R9 M375X is a lot (about 105%) faster with regards to anisotropic filtering than the Radeon R7 M260X. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon R9 M375X is a better choice, by a large margin. (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 maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number 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 in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
