Official AMD Ryzen Benchmarks, Reviews, Prices, and Discussion

[Shivansps]

The tr demo was done with the same version of blender used on the 1800x demo? Because blender got faster on the newer version.

 

[The Stilt]

Do you know the topology of the 4 SOC solution? is it mesh or ring? I assume its ring based of the original Fud leaks around the APU.

The leaked schematic is correct.

Yes. I hope they can use the same platform with vega or nv gfx because that 580 is an inefficient gpu.

About time we see 1700 mb
Certainly there is a small market for such gigantic cpu power in a mobile form. Heck my old sb i7 4c8t was 45w as i recall.

The A12 was pointless to put into a notebook.

incorrect

No one would have bought that A12 notebook, because there were better alternatives.

incorrect

Get a far better Intel chip and match with a discreet GPU for far better performance.

because that solves everyone's use case and budget for a laptop... brilliant

 

[Mopetar]

incorrect

Okay fine, almost no one would have bought it which is why companies weren't jumping all over each other to make it. If you have a niche, small maker product the margins need to be good and that wasn't the space AMD was playing in.

 

[jpiniero]

OEMs love 15W models... and at 15W, Bristol Ridge throttles to the point where it even loses to Intel's IGP in games. So you can see why OEMs were never really interested.

Now that we know for sure that the Zeppelin die has 32 PCIe lanes, is it feasible to see a refreshed Ryzen (2XXX) next year with all lanes unlocked?

Can the current motherboards support it?

Maybe the motherboard makers kept it a secret and already added the needed extra traces that can be activated with a bios update in the future?

Am I nuts?

Don't know what your on about, the physical options are clearly detailed in the 17h reference model http://support.amd.com/TechDocs/54945_PPR_Family_17h_Models_00h-0Fh.pdf

There are 32 physical interfaces to use for SATA, PCI-e, nvme, chip set.

I'm sorry. I'm not an engineer and I'm having trouble navigating through that document. Can you point me to where 32 physical interfaces are specified and if all of them are accessible in Ryzen 5/7?

All I found was this: "Max PCIe/module: 24 lanes" on page 28. I also know that SATA, USB, nvme etc already use these 24 lanes, thus 8 other lanes are inactive.

Thanks.

As I haven't found anything else either just a guess: As AM4 is prepared for APUs the missing lanes may be reserved for use with the iGPU (which obviously doesn't exist in the current Ryzen models).

 

[T1beriu]

I don't think that's the case because the iGPU Ryzen is a brand new SoC, thus new lane configuration and the 8 missing lanes would still be missing from the Threadripper and EPYC range, but that's not the case.

 

[moinmoin]

I'm not talking about the 8 lanes being reserved on Zeppelin dies, just AM4 boards. The Threadripper and EPYC boards are not prepared to output the video of APUs, AM4 boards are.

Edit: But that does bring up interesting considerations, as the Ryzen Mobile SoC will be one CCX so only 16 PCIe lanes altogether. AM4 boards already using more than 16 PCIe lanes means desktop APUs will have to contain two CCXs (unless it's possible to disable parts of the lanes/IO just like video out currently is).

 

[T1beriu]

You're bringing an interesting point, that some pins on the boards might be reserved for the PCIe lanes that take the iGPU signal to the video output ports. You might be right if that's how things work.

desktop APUs will have to contain two CCXs

There's no proof of that happening (leaks), at least not in the near future because the die would be more than 300 mm2, too big, thus too expensive for the market. Raven Ridge APU is just one CCX at around 220 mm2, Ryzen (2 CCXs) is 195 mm2 so no room for extra iGPU.

 

[Glo.]

The PCIe lanes are not connected to CCX's. Its separate subsystem of the chip. For example Ryzen 5 1400 is 4C/8T CPU, made from single CCX, and it still has 32 PCIe lanes.

 

[imported_jjj]

From that PDF on page 27 and ofc there is the diagram on page 28.

Two 8x16 PCIe® controllers supporting Gen1/Gen2/Gen3. Note that SATA Express is supported by
combining an x2 PCIe port and two SATA ports on the same 2 lanes.

• Enterprise 12G (E12G) Combo PHYs, PCS, and UPI muxing
• 6 x4 PHYs plus 5 x2 PHYs - 2 of these are in the upper right corner of that diagram
• PHYs can support the following controller types: PCIe, WAFL, xGMI, SATA, and Ethernet (SGMII
1000/100/10, 10GBASE-KR, 1000BASE-KX protocols). In addition, SATA Express can be
supported by combining PCIe and SATA controllers on the same lanes with a GPIO for a device to
indicate its controller type.
• PHY muxing is provided that allows different package or board configurations to enable a single
PHY to support functionality from multiple on-die controllers


As for Raven Ridge, that should be x16 available with more allocated for other I/O but no idea how many in total. It's a laptop part so no need to go overboard.

The 1400 is still dual CCX's it just has half the cache disabled on both CCX's. The timing of the R3 makes me think that the R3 could be single CCX chips but even then could be RR with the GPU disabled. But you are right it's part of the uncore.

Looks like Ryzen 7 prices have received a cut on Newegg.
1700 - 315$
1700X - 350$
1800X - 460$

The 1800X recieved the cut a week or so back. Positioning for ThreadRipper?

Or just adjustments for the inventory channel. I'd guess the 1700 is selling quite a bit better than either X model.

It's an official price cut:

1700X may be worth picking up on a deal, now.

How can you tell from that article that is an official price cut? Shouldn't everyone report it?

TPU transforms itself day by day into w-junk-tech. That's why I'm asking.

 

[lolfail9001]

Yeaa they could and the results would be meaningless then. Whats the purpose then? I dont find it likely.

Remember that Crossfire demo? It was apparently a ThreadRipper demo. And you dare question AMD doing something meaningless? Haha.

Dang, price cuts two months after release are not an indicator that things are well for Ryzen.

 

[DrMrLordX]

Either that, or CPU supply is outstripping motherboard supply, so they're correcting to keep the R7 chips moving off the shelves (instead of selling cheaper R5 chips). Given the OEM situation with AM4 I would not be surprised by that.
