Radeon HD 6670 (OEM) vs Radeon R9 M370X

Intro

The Radeon HD 6670 (OEM) uses a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this specific model. It features 480 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Compare those specifications to the Radeon R9 M370X, which features core speeds of 800 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M370X should perform just a bit faster than the Radeon HD 6670 (OEM) in general. (explain)

Radeon R9 M370X 72000 MB/sec
Radeon HD 6670 (OEM) 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The Radeon R9 M370X is quite a bit (approximately 67%) more effective at anisotropic filtering than the Radeon HD 6670 (OEM). (explain)

Radeon R9 M370X 32000 Mtexels/sec
Radeon HD 6670 (OEM) 19200 Mtexels/sec
Difference: 12800 (67%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M370X is the winner, and very much so. (explain)

Radeon R9 M370X 12800 Mpixels/sec
Radeon HD 6670 (OEM) 6400 Mpixels/sec
Difference: 6400 (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: Bandwidth is the max amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
