My i5-3470 system has served me well; but I want bragging rights. So, I hope to spec a high-end Ryzen system that totally rocks and completely works. Rocks = it just does it, almost zero waiting. Completely works = nothing that just adds eyewash; like a Windows 98 system with one GB of system memory or adding unicorn stickers.
CPU: Ryzen 8-core 16 thread, would say 1800X, but might be unnecessary support of marketing based binning. (tested products marketed as 1800X, 1700 may be an 1800X without a sticker)
Motherboard: X370 chipset board featuring PCIe x4 M.2 socket for a 512MB boot drive, good support for 4-channel memory at higher speed and quicker timings; or, 2-ch memory might be as good as it gets.
System Memory: Where I see a swamp of marketing claims and limited proofs. Gigabyte's GA-AX370-Gaming 5 motherboard memory QVL shows 4-ch support at DDR4 2666 with several brands at 16-16-16-36 and 2-ch support at up to DDR4 3200 with one brand at 14-14-14-34
Graphics: Either carry on with my aging 650 ti Boost until the Vega boards arrive latter; or, add a placeholder until the dust settles. The Sapphire R9 Fury Nitro is appealing, but it is end of life.
I'm looking for informed analysis. I know the NDAs have not expired, so no one has actually built systems that they can talk about. But, will 2-ch interleaved memory vs 4-ch interleaved memory in a Ryzen system test differently than in an X99/i7-5820K system?
Gordon Mah Ung, an executive editor at PCWorld, opines that 4-ch memory only adds to SiSoft Sandra’s memory bandwidth test, 4-ch = 200% 2-ch. He bases that on comparing one i7-5820K processor in two different X99 motherboards with 16GB of total system memory in 2 and 4 DIMM slots. Productivity workware, zipping/unzipping, games and video encoding showed no meaningful difference, pretty much 99.999 vs 100 across both systems. http://www.pcworld.com/article/2982965/ ... mance.html
So, how many people think (or secretly know) that AMD has matched Intel's system memory performance; OR, has AMD gotten improved real world results from 4-ch memory and reversed the super socket seven debacle.
Super socket seven, SS7, was AMD holding onto socket seven while Intel introduced Slot One and the 440BX chipset that sealed their lock on world domination. I read a comparison of hard drive transfer speeds and that was the end of AMD for me until they gave up Slot A. I have fond memories of running a Celeron 366 as a Celeron 550. And, then a pair of them. (Yeah Bay Bee!!!)
Reversing the SS7 debacle would mean AMD's Ryzen gets a real performance boost from 4-ch memory bandwidth and Intel is only using it as a unicorn sticker.
Has anybody wasted time, money, tech subscriptions or whatever to analyze this geeky topic? Or, must I wait for someone to officially get their hands on the material necessary to replicate Mr Ung's experiment using AMD parts? AMD should be motivated. If Ryzen uses 4-ch memory better than Intel's chips.
Intel is certain to make sure that everyone knows Intel's AVX support is "better" than AMD's. At least that was my take away from early analyses of Ryzens kicking Intel booty overall but not being perfect.
So there it is. Is a Ryzen CPU and X370 chipset able to use 4-ch system memory effectively? Or, should I concentrate on faster memory for 2-ch?
