Radeon R7 M265 vs Radeon R9 M375

Intro

The Radeon R7 M265 comes with a clock speed of 725 MHz and a DDR3 memory speed of 1000 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Compare those specifications to the Radeon R9 M375, which has clock speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375 will be 10% quicker than the Radeon R7 M265 overall, due to its higher data rate. (explain)

Radeon R9 M375 35200 MB/sec
Radeon R7 M265 32000 MB/sec
Difference: 3200 (10%)

Texel Rate

The Radeon R9 M375 will be a lot (about 133%) more effective at AF than the Radeon R7 M265. (explain)

Radeon R9 M375 40600 Mtexels/sec
Radeon R7 M265 17400 Mtexels/sec
Difference: 23200 (133%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M375 is the winner, by a large margin. (explain)

Radeon R9 M375 16240 Mpixels/sec
Radeon R7 M265 5800 Mpixels/sec
Difference: 10440 (180%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
