Radeon HD 3850 1GB vs Radeon R5 M230

Intro

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

Radeon HD 3850 1GB		10688 Mtexels/sec
	Difference: 4912 (46%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 3850 1GB is superior to the Radeon R5 M230, by far. (explain)

Radeon HD 3850 1GB		10688 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 7568 (243%)

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 max amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be 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 the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics 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 Raster Operations Pipelines by the clock speed of the card. 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
