Radeon HD 6570 (OEM) 2GB vs Radeon R5 M230

Intro

Compare those specs to the Radeon R5 M230, which features a clock frequency of 780 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 64-bit bus, and makes use of a 28 nm design. It is made up of 320 SPUs, 20 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 6570 (OEM) 2GB should theoretically be a lot superior to the Radeon R5 M230 overall. (explain)

Radeon HD 6570 (OEM) 2GB		64000 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 48000 (300%)

Texel Rate

Both cards have exactly the same texel fill rate, so theoretically they should perform equally good at at anisotropic filtering. (explain)

Pixel Rate

The Radeon HD 6570 (OEM) 2GB is quite a bit (approximately 67%) better at anti-aliasing than the Radeon R5 M230, and will be able to handle higher screen resolutions better. (explain)

Radeon HD 6570 (OEM) 2GB		5200 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 2080 (67%)

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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
