USB 3.0 Backup
Our backup testing takes a typical set of user files – specifically just under 8000 files across 4 GB, some large files but mostly small. For USB 3.0 testing, these files are copied from a 4 GB RAMDisk onto an OCZ Vertex3 which is connected via a SATA 6 Gbps to USB 3.0 device. We use all the USB 3.0 protocols available - the UASP protocol that the ASMedia controller on our test bed affords as well as the chipset driven Intel USB 3.0 under ASUS' Turbo mode. The copy test is conducted using DiskBench, a copying tool with accurate copy timing.
Across the result range, no matter which protocol is used, our copy testing shows up to a 7% decrease in copy times over the USB 3.0 protocol moving from DDR3-1333 to DDR3-2133. In some cases, such as using Intel Turbo mode, the timing levels out around DDR3-1866, but in the case of UASP, the DDR3-2133 C9 kit provides the best result. Interesting to note that in the case of UASP, having a smaller CL value is more important than having a larger speed value.
Thunderbolt Backup
Similar to our USB 3.0 Backup test, Thunderbolt testing carries the same files directly through to our LittleBig Disk which contains two 120 GB Intel SSDs in RAID-0. The copy test is conducted using DiskBench, a copying tool with accurate copy timing.
Thunderbolt tests are never as consistent as USB timing – the results shown are the average of the best three obtained. Typically the best results come after leaving the Thunderbolt device for 30 seconds or longer after the last copy test as the TB device does an amount of post processing after the data has officially been sent. Nevertheless, a gradual decrease in copy times is exhibited from DDR3-1333 to DDR3-2400.

"Besides, do people really play games with IGP?"They're definitely more likely to play games on a more powerful IGP like AMD's. I thought the whole point of AMD's Fusion lineup was that you could do light gaming on the IGP itself.

Exactly! no one buys shitty AMD products anymore......Boogaloo - Thursday, October 18, 2012 - link
There are already plenty of benchmarks out there for memory scaling on AMD's APUs. This is the first time I've seen an in-depth look at how memory speed affects Intel's IGP performance.ssj4Gogeta - Thursday, October 18, 2012 - link
That's what I was thinking as well.I'm hoping for another article using Trinity. :)

I'm not sure A10 supports DDR3-2400 (DDR3-1866 was the fastest memory supported)Medallish - Friday, October 19, 2012 - link
The A10 has AMP profiles(Like XMP on Intel) up to 2133MHz, however, there's always overclocking, I'm pretty sure Ivy Bridge doesn't suppoort 2400+MHz memory natively either. I'm looking at an FM2 board by Asrock which they claim can support 2600MHz memory.IanCutress - Friday, October 19, 2012 - link
My A10-5800K sort of liked DDR3-2400, then it didn't like it. Had to go back one to 2133 for the testing. Even with bumped voltages and everything else, the CPU memory controller couldn't take it. Perhaps the sample I have is a dud, but that was my experience.Ian

I concur.Pointless review anyway. The summary should have read: High-Clocked Memory only needed if your primary usage is either competitive benchmarking or WinRAR compression.

Did you know that before you read the article though? This is Anandtech, and I like to think I test things thoroughly enough to make reasoned opinions and suggestions :) Having a one sentence summary wouldn't have helped anyone in the slightest.Ian

Nothing is better done on AMD products idiot.....
