Radeon HD 6570 (OEM) 2GB vs Radeon R9 M270X

Intro

The Radeon HD 6570 (OEM) 2GB features a GPU core speed of 650 MHz, and the 1024 MB of GDDR5 RAM runs at 1000 MHz through a 128-bit bus. It also is made up of 480 SPUs, 24 Texture Address Units, and 8 ROPs.

Compare those specifications to the Radeon R9 M270X, which has a core clock frequency of 725 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M270X should perform just a bit faster than the Radeon HD 6570 (OEM) 2GB in general. (explain)

Radeon R9 M270X 72000 MB/sec
Radeon HD 6570 (OEM) 2GB 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The Radeon R9 M270X is a lot (more or less 86%) more effective at texture filtering than the Radeon HD 6570 (OEM) 2GB. (explain)

Radeon R9 M270X 29000 Mtexels/sec
Radeon HD 6570 (OEM) 2GB 15600 Mtexels/sec
Difference: 13400 (86%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M270X is the winner, by a large margin. (explain)

Radeon R9 M270X 11600 Mpixels/sec
Radeon HD 6570 (OEM) 2GB 5200 Mpixels/sec
Difference: 6400 (123%)

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 max amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
