Testing Different Memory Speeds on AMD's A8-3850 Llano APU

Posted on Thursday, July 14 2011 @ 23:29:00 CEST by


Legit Reviews has had a number of readers write in saying that they want to see performance numbers of AMD's A-Series APUs on the A75 chipset at 1333MHz, 1600MHz and 1866MHz. When we did our launch article on the A8-3850 we ran 1866Mhz memory, but since this platform is very budget friendly we know our readers also want to see performance numbers at 1333MHz and 1600MHz. Read on to see how 'Llano' performs at three different memory clock speeds and also with 16GB of memory in a 4x4GB configuration! Check it out at Legit Reviews.
"We found that the memory bandwidth ranges from 13GB/s to 16GB/s with typical dual channel memory kits on our AMD A8-3850 APU and Gigabyte A75-UD4H motherboard. This difference doesn't sound that great, but a 3GB/s increase when dealing with 13GB is a very nice 23% performance increase. Most of this performance gain is seen when moving up from a 1333Mhz to a 1600MHz memory kit is where you'll see the largest performance jump. For example 2x4GB 1333MHz CL8 memory kit was able to hit ~12.7GB/s memory bandwidth, but the 2x4GB 1600MHz CL8 memory kit has ~15.0GB/s of memory bandwidth, which is a very nice 18% improvement over 1333MHz..."
