Radeon R7 M265 vs Radeon R9 M365X

Intro

The Radeon R7 M265 has a GPU core clock speed of 725 MHz, and the 2048 MB of DDR3 RAM is set to run at 1000 MHz through a 128-bit bus. It also is made up of 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the Radeon R9 M365X, which has GPU clock speed of 925 MHz, and 4096 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Radeon R9 M365X 72000 MB/sec
Radeon R7 M265 32000 MB/sec
Difference: 40000 (125%)

Texel Rate

The Radeon R9 M365X should be a lot (approximately 113%) more effective at texture filtering than the Radeon R7 M265. (explain)

Radeon R9 M365X 37000 Mtexels/sec
Radeon R7 M265 17400 Mtexels/sec
Difference: 19600 (113%)

Pixel Rate

The Radeon R9 M365X will be much (about 155%) better at FSAA than the Radeon R7 M265, and will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R9 M365X 14800 Mpixels/sec
Radeon R7 M265 5800 Mpixels/sec
Difference: 9000 (155%)

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 data (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 can be processed in one second. This is worked out by multiplying the total texture units of the card by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant 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.
