Radeon HD 5670 vs Radeon R9 M365X

Intro

Compare all that to the Radeon R9 M365X, which has core speeds of 925 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M365X should be 13% faster than the Radeon HD 5670 in general, due to its higher bandwidth. (explain)

Radeon R9 M365X		72000 MB/sec
Radeon HD 5670		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon R9 M365X should be much (more or less 139%) faster with regards to AF than the Radeon HD 5670. (explain)

Radeon R9 M365X		37000 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 21500 (139%)

Pixel Rate

The Radeon R9 M365X is quite a bit (about 139%) better at anti-aliasing than the Radeon HD 5670, and will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon R9 M365X		14800 Mpixels/sec
Radeon HD 5670		6200 Mpixels/sec
	Difference: 8600 (139%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
