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

AMD Confirms Key "Summit Ridge" Specs

AMD CEO Lisa Su, speaking at the company's Computex reveal held up the most important CPU product for the company, the new eight-core "Summit Ridge" processor. A posterboy of the company's new "Zen" micro-architecture, "Summit Ridge" is an eight-core processor with SMT enabling 16 threads for the OS to deal with, a massive 40% IPC increase over the current "Excavator" architecture, and a new platform based around the AM4 socket.

The AM4 socket sees AMD completely relocate the core-logic (chipset) to the processor's die. Socket AM4 motherboards won't have any chipset on them. This also means that the processor has an integrated PCI-Express gen 3.0 root complex, besides the DDR4 integrated memory controller. With the chipset being completely integrated, connectivity such as USB and SATA will be routed out of the processor. The AM4 socket is shared with another kind of products, the "Bristol Ridge" APU, which features "Excavator" CPU cores and a 512-SP GCN 1.2 iGPU.

so what do you think, is this good or bad ? having that many features integrated to the chip itself rather than being on the mobo.

Actually it's a redesign of Bulldozer shopped to AMD by Jim Keller.

Since when? Everything I've read on it says its a total ground up design. Obviously Jim Keller was on board for a lot of it, but to say its just a reworked bulldozer?

This is the first time in a very long time that we engineers have been given the total freedom to build a processor from scratch and do the best we can do. It is a multi-year project with a really large team. It's like a marathon effort with some sprints in the middle. The team is working very hard, but they can see the finish line. I guarantee that it will deliver a huge improvement in performance and power consumption over the previous generation. ”

If motherboard manufacturers wants extra USB, SATA ports, etc. they can use the Promontory chip: https://benchlife.info/amd-summit-ridge-platform-structure-confirm-05062015/

And this is apparently a HP OEM AM4 board:

Nice find. They're really sticking to their mountain naming scheme, huh?

So a promontory chip is like a PCI-e extender board, essentially?

EDIT: Crap! Is that dual-channel memory I see in the diagram? I hope that wont be for all Zen chips. I want quad-channel minimum.

It's an old picture from last year so there's a chance AMD may have changed that, but for the normal consumer there's still not much real life performance difference beyond dual channel.

Agreed-ish. But I'm not a normal user. I do programming and DB work as a consultant sometimes and quad-channel is desirable to me. It also makes a difference with some graphics work so I would hate to see Zen held back from what it could be by this.
 
First Bristol Ridge based laptop available now with the highest end SKU:

http://store.hp.com/us/en/pdp/Laptops/hp-envy-x360---15z-touch laptop-t5y05av-1

Looks like a great spec apart from one little thing:

8GB DDR4-2133 SDRAM (1 x 8GB)

Try to customise the laptop and you can't add another one.

FAIL!!

It seems it only has one RAM slot acccording to this thread:

https://www.reddit.com/r/Amd/comments/4m7rvx/just_bought_3_hp_envy_x360_15z_touch_laptops/

I just got off chat support and they told me that this computer only has 1 RAM slot, and that the RAM is not user-upgradeable. I'd imagine the same thing applies to the HD.

Edit!!

The OP of that thread said they would check to see if the laptop has a free RAM slot.

That sucks. AMD have eternally had problems with getting laptop manufacturers to give their chips a decent home. Anandtech did an extremely good article on it a while back (link) with Carrizo and how it was held back. The lack of OEMs willing to give it a dual-channel set up was a big factor in this, too. So it looks like the cycle perpetuates yet again.

Hopefully there are some better Bristol Ridge laptops on their way.

Correct me if I'm wrong, but Bristol Ridge isn't Zen is it?

Now I'm sure we've had a similar situation before, but are people expecting Zen to hit this year, given they've just launched Bristol Ridge? I really can't see it (Yet the entire Internet is telling me Zen's Q3 2016, which starts in 27 days.)
