Radeon R9 M365X vs Radeon RX 470

Intro

The Radeon R9 M365X has clock speeds of 925 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the Radeon RX 470, which uses a 14 nm design. AMD has clocked the core speed at 926 MHz. The GDDR5 memory works at a speed of 1650 MHz on this particular model. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 470 should be 193% quicker than the Radeon R9 M365X overall, because of its higher data rate. (explain)

Radeon RX 470 211200 MB/sec
Radeon R9 M365X 72000 MB/sec
Difference: 139200 (193%)

Texel Rate

The Radeon RX 470 is quite a bit (about 220%) more effective at AF than the Radeon R9 M365X. (explain)

Radeon RX 470 118528 Mtexels/sec
Radeon R9 M365X 37000 Mtexels/sec
Difference: 81528 (220%)

Pixel Rate

The Radeon RX 470 will be much (about 100%) better at anti-aliasing than the Radeon R9 M365X, and should be able to handle higher resolutions while still performing well. (explain)

Radeon RX 470 29632 Mpixels/sec
Radeon R9 M365X 14800 Mpixels/sec
Difference: 14832 (100%)

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 MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
