It seems that Joker fake his bench results for his own benefits.

I always enjoyed videos from Steve @ Hardware Unboxed as well as Tom @ OC3D

A nice video from AdoredTV highlighting on why low resolution benchmarking is irrelevant

After reading the thread on reddit and the pcpaper article (link above), and dig a little bit more searching I have found better understanding regarding XFR
which has never been explained properly by many reviewers. And there were some misleading info reported by many Youtube reviewers too.

XFR actually works on all Ryzen chip, not just X-versions.
1800X, 1700X and 1700 all have XFR. The difference is that 1800X and 1700X has 100MHz extra over normal boost, while 1700MHz is only 50MHz.

The way a boost and XFR works on Ryzen 8-cores is something like this
1800X
Base clock: 3600MHz @ 8 cores
Boost 1 : 3700MHz @ 8 cores
Max Boost : 4000MHz @ 2 cores
XFR : 4100MHz @ 2 cores (temp <60°C, cpu power <128W)

1700
Base clock: 3000MHz @ 8 cores
Boost 1 : 3100MHz @ 8 cores
Max Boost : 3700MHz @ 2 cores
XFR : 3750MHz @ 2 cores (temp <60°C, cpu power <128W)

Initially, early AMD reports mention that XFR is supposed to have no fixed limit, but in the end they decided to lock it at only 100MHz extra.

Some reviewers claim that max boost and XFR only works on one core, but if pcpaper article is correct then it should be 2 cores instead. One core max boost is probably due to buggy bios or unoptimized threads or something like that.

R5 1600X might be a better gaming option than R7 1700 because:
- lower pricing
- much higher base clock by 600MHz
- max clock on all cores 3700MHz @ 6-cores vs 3150MHz @ 8-cores

I think the huge extra mhz at the base is enough to offset the performance from lacking 2 extra cores in terms of gaming.

some shops in lowyat have ready stocks of all the R7
it's the motherboards that's quite limited though

goldfries Is Ryzen bus-clocking friendly?

I mean, can you increase the bus clock without affecting the stability of other peripherals like pcie clock, sata, and all those stuff?

can you try rising the bclk to 110mhz see if it can run 2933mhz.

lower the cpu multiplier so that you're not clock limited. on average, R7 doesn't really like anything higher than 4ghz even if you put more voltage on it.

The current X370 boards available right now have better power delivery than available B350 motherboards.
However a manufacturer can choose to manufacture a B350 board with similar power delivery and components as X370, but it probably won't be as cost efficient.
It's more of a marketing choice rather than chipset limitation.

I'm hoping for good sub-RM400 B350 boards, that will make AMD much much more competitive in the midrange segment.

TTL @ OC3D overclocked 1800X on MSI B350 Tomahawk at 4.0GHz (1.4Vcore) without much issue. He said the voltage reading was much more stable compared to other more expensive X370 boards he had.
Other than that he just had to manually tune the RAM to run at 3200mhz.

This is just my wild imagination and speculation.

I think Ryzen 3 will be a single CCX processor based on early Raven Ridge with iGPU and SMT disabled. Or it could have no on-die iGPU at all, since the Zen design is basically modular.

Corsair LPX 3000 is a problematic RAM for Ryzen, I hope people stop buying it for the moment unless you're really desperate for a DDR4 and there's no other option available for you.

Because if you guys look at most Ryzen build with that RAM, I think pretty much everyone had problem with clocks.

Raven Ridge desktop will only coming out next year.
2H 2017 Raven Ridge is mobile only according to AMD roadmap

Is the manufacturing country SKU specific, or is it just random? I mean for example 1700 MiM only, or also available MiC?

The current stocks don't come with Wraith Max.
It will be available as bundled option in the future.

you can overclock just fine with a B350 mobo.
the asus b350 prime seems to be quite decent
msi b350 tomahawk also not bad

the only major reason you'd want an x370 is you want to do 'extreme overclocking' because they generally provide higher spec power phase design, and SLI support.
4GHz OC with below 1.45Vcore should be fine on most current B350 mobos.

could have been cheaper if RM was strong

The board supports 3200mhz ram out of the box
