Radeon R7 M265 vs Radeon R9 M375

Intro

The Radeon R7 M265 uses a 28 nm design. AMD has clocked the core speed at 725 MHz. The DDR3 RAM works at a speed of 1000 MHz on this model. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Compare all of that to the Radeon R9 M375, which has core clock speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 memory. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

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 (approximately 133%) faster with regards to 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 using a high resolution is important to you, then the Radeon R9 M375 is a better choice, 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 max amount of data (measured in MB per second) that can be transferred past 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 type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 reach the max fill rate.
