Radeon R7 M265 vs Radeon R9 M375

Intro

The Radeon R7 M265 features clock speeds of 725 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Compare all of that to the Radeon R9 M375, which makes use of a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The DDR3 RAM works at a frequency of 1100 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M375 should perform a little bit faster than the Radeon R7 M265 overall. (explain)

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

Texel Rate

The Radeon R9 M375 should be a lot (approximately 133%) faster with regards to anisotropic filtering 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 lots of anti-aliasing is important to you, then the Radeon R9 M375 is superior to the Radeon R7 M265, 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 maximum amount of information (measured in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
