Radeon HD 6670 (OEM) 1GB vs Radeon R9 M270X

Intro

The Radeon HD 6670 (OEM) 1GB comes with a GPU core clock speed of 800 MHz, and the 1024 MB of GDDR5 memory runs at 1000 MHz through a 128-bit bus. It also is made up of 480 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Compare all that to the Radeon R9 M270X, which uses a 28 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this particular model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M270X should in theory be a small bit superior to the Radeon HD 6670 (OEM) 1GB overall. (explain)

Radeon R9 M270X 72000 MB/sec
Radeon HD 6670 (OEM) 1GB 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The Radeon R9 M270X will be much (approximately 51%) more effective at texture filtering than the Radeon HD 6670 (OEM) 1GB. (explain)

Radeon R9 M270X 29000 Mtexels/sec
Radeon HD 6670 (OEM) 1GB 19200 Mtexels/sec
Difference: 9800 (51%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M270X is a better choice, and very much so. (explain)

Radeon R9 M270X 11600 Mpixels/sec
Radeon HD 6670 (OEM) 1GB 6400 Mpixels/sec
Difference: 5200 (81%)

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 data (in units of megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video 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 maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
