*** AMD "Zen" thread (inc AM4/APU discussion) ***

So going by that its a 3.4 Base with a 3.8 Boost OC'd to 4ghz.. 8/16 chip 95w

So is that an X model with XFR? 6th revision too.

It's apparently a qualification model according to Videocardz as it's the same model used for the earlier leak with the Passmark scores. It's most likely the XFR in action and if keeping to 4Ghz during 3DMark it would mean that is the all cores clockspeed as 3DMARK likes more threads.

Edit!

It's quite clever - AMD can advertise these as 95W with XFR off,but if XFR does work well the CPUs will exceed that TDP for extra performance so now you can see why the cooler is so large.

How do you explain the 3.7/3.8/4.0GHz boost on the 1700/1800 models then? I mean, the 1700 is supposed to have a 3.7GHz boost at a TDP of 65W and that's across 8 cores. Surely a 4c model then, should be able to reach this level of boost?

Something just doesn't seem right there...

Suggests to me the clock rates are silicon limited rather than anything else.

B350 motherboards below $90 is just ridiculous, shame on you Intel! :D

Yeah,the B350 seems well priced - just checked the cost of the Asus Z270 Hero,its £240,so £210ish for the X370 is comparative cheaper,but still a lot of money for a consumer socket motherboard.

True but unless you want SLI/CF, you don't really need X370. X370 is more aligned to X99 in that respect.

From what I read in that article,it seems some of the B350 motherboards might support it too.

Also from what I have read,AM4 motherboards will use a 6 phase VRM as standard.

Edit!!

Checking the equivalent Asus motherboard pricing for socket 1151,it looks like the Asus AM4 motherboards will be slightly lower in price but close to the socket 1151 equivalents if the pricing estimates are true.

I would imagine only X370 will support 16x/16x but B350 motherboards with two 16x slots would work at 8x/8x.

By the way, do we know anything about which Ryzen models will support VT-d (or equivalent) for virtualisation support? It'd be annoying if only the Pro models do, since it's essential for PCIe passthrough.

I don't see why they wouldn't looking at the previous generations,but I assume the motherboard will need to be compatible too,going from what I read about virtualisation in the past?

So the Ryzen CPU is 8 cores and 16 threads,right??

Well,each Ryzen CPU is made of two 4 core modules called a CCX:

https://www.techpowerup.com/225248/amd-zen-quad-core-subunit-named-cpu-complex-ccx

So each CCX,has the 4 cores with all the caches required including L3 cache.

The pair of modules will share a dual channel memory controller and associated chipset logic in the CPU.

So what I expect the APU will be,is a semi-custom version of the CPU with one of those CCX modules swapped out for a GPU module,sharing the same memory controller.

The only way I can see an 8C/16T laptop is if a large OEM decides to shoehorn a desktop chipset into a large laptop and use desktop CPUs like that X79 based one I linked to.

Ahhh ok got ya - oh yeah I don't want an APU, I want a full on laptop - desktop replacement, fed up of 7700k intels - I don't want cpu graphics, I want a beast CPU with dedicated graphics cards.

Proper virtualisation support was very motherboard dependant on AM3.

There was only a handful of boards that had the proper IOMMU support required. (A couple of Gigabyte offerings and a couple from Asrock. The Asrock 970 Pro in my server has worked flawlessly with ESXI hardware pass through on everything from a Sempron 190 right up to FX chips)

Some leaks on US pricing of the Asus motherboards based on Aussie pricing:

http://wccftech.com/amd-ryzen-am4-asus-motherboard-prices-leaked/

LOL,at the pricing of the Asus X370 motherboards if true.

Edit!!

Just checked the pricing of the Asus Z270 motherboards - WTF??

https://www.overclockers.co.uk/asus...cket-1151-ddr4-atx-motherboard-mb-68q-as.html

£240!!

So even at £200 the X370 is "cheaper" - thats mental pricing for the top end consumer line motherboards for both sockets.

i see your £240 and raise you to £500

Damn, I only paid £260 for my Rampage IV Gene lol.

Considering how feature/connectivity light most of the AM4 boards seen so far are I was expecting sub £200 for a RoG/Sabretooth :(

God I wish the AM4 boards we have seen so far had PCI-E layout that good :(
