Radeon HD 5670 vs Radeon R9 M365X

Intro

Compare those specs to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has set the core speed at 925 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this particular model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M365X should in theory perform a small bit faster than the Radeon HD 5670 overall. (explain)

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

Texel Rate

The Radeon R9 M365X will be a lot (about 139%) faster with regards to texture filtering 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 much (more or less 139%) better at full screen anti-aliasing than the Radeon HD 5670, and will be able to handle higher screen resolutions without losing too much performance. (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 largest amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 are processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
