Id take those with a pinch of Salt, Jagat already done a sample of 10 x 1700 and got better results than theirs, id rather trust their review than the review of Silicon Lottery who make money from selling binned chips, something oddly tells me its within their interest to skew results towards sales for themselves

Not much detail on how many they sampled, and I'm sure their bias. They were saying they're trying to bin as low a voltages as possible. I'm sure you can go higher with them at exceedingly higher voltages... Guess we'll see more details as we start getting mobos!

@Gibbo are you getting the Asrock Taichi in tomorrow?

Check out their ocnet thread : http://www.overclock.net/t/1623496/ryzen-binning

Their testing methodology is different.

"If you're familiar with how we bin things, the 3.8 bins mean they weren't able to do realbench at 3.9 with 1.408V or less which doesn't necessarily mean they can't do 3.9 at a higher voltage."

The problem with the frametime graph is that it's for just 1 game in DX11. If you look at the DX12 graph then the 7700k comes out on top.

Also looking at the graphs for other games the 7700k does well and wouldn't suggest there are any hitching problems with that chip.

This video shows it even more, I like Raw footage more than White paper tbh its one reason I rate DigitalFoundry very highly. Its not only me either saying this just look at the comments.

Well I can see hitching on the 1700 in that video as well, just after 1:47.

There's a whole host of reasons to be honest and when looking at the frametime graphs the 7700k is usually better off in the other games.

 

[teppic]

I was going to wait 2-3 months to get a 1700 but all these vids and positive results are tempting me...

Looking forward to 8pack's details on the Taichi as on paper it looks excellent.

So AMD has finally announced a launch date for Naples, their enterprise CPU line. It's coming in the second quarter; and packed to the brim with new tech.

Given how well Ryzen handles proffesional workloads, and does exceptionally well in Linux; Naples looks set to finally get AMD back into the place where it truly matters.

I believe many people will welcome some healthy competition in the enterprise market; as it usually trickles down to the HEDT, to only further benefit consumers.

I personally cannot wait to see how AMD performs in this market, and it reminds me of the high days of the Operteron. Who knows, they might even be unlocked, and Asus and other motherboard manufactures might grace us with Single Socket boards. Allowing for some whopping custom build workstations.


Coming with 32 physical cores and 64 Logical, if priced correctly, AMD is on to a real winner.

Their "Infinity-Fabric" is there to connect the CPUs, to give a 2x performance increase.

They're also doubling the memory channels to 8 per socket.

While Ryzen is currently limited to 24 Lanes I/O, Naples will be significantly upping that; to 128!

And you would be correct But thats just one single hitch, check out the continue amount stutter the 7700K gets in GTA 5, Battlefield notice once the CPU hits 90+ load

 

[IFW]

I bet it still wouldn't run GTA 3 in 320x200 at 1200Hz!

Seriously: looks awesome

 

[Curlyriff]

1700 4.1Ghz at 1.48, woop! Shame I am too scared to run that for 24/7 haha

Why 1.55V is safe volts under warranty? Seems fine. Temps below 80 degree when there? If so then good to go What your RAM speeds at this? 8-pack is suggesting that if you are not getting 3000Mhz RAM speed at 4.0 or 4.1GHz then it is work clocking to 3.9GHz and then getting 3000MHz RAM as performance will be same.

And with that your volts and temps lower. However if you are at or close to 3000Mhz on RAM then yeah stick to 4.1GHz CPU. Also would be worth doing a few game runs or whatever you use it with the two different settings to see if your CPU or RAM increase improve performance either way.

 

[mortals]

super pleased to hear about these

I am disappointed the guy didn't suggest the pretend knob he was turning would go to eleven tho

In all seriousness, Naples looks really interesting some of the tech aspects seem amazing.

 

[LoadsaMoney]

'Areet guys, ows it goin'

EDIT: Vid removed due to swearing.

 

[Harlequin]

Doesn't seem to explain it... He just mentioned "High Performance Mode", as in the power setting profile right? If so, it's just a profile of settings that you can change independently. What setting is it? "Minimum Processor State"? If so, that will stop the underclocking (Pure Power) though right?

Control Panel\Hardware and Sound\Power Options select `high performance` - its a windows feature

You shouldn't joke about the knobs when twisting AMD's Naples.

Info provided by Siliconlottery.com.

Ryzen 7 1700
93% reach 3.8GHz @ 1.376V
70% reach 3.9GHz @ 1.408V
20% reach 4.0GHz @ 1.440V

Ryzen 7 1700X
100% reach 3.8GHz @ 1.360V
77% reach 3.9GHz @ 1.392V
33% reach 4.0GHz @ 1.424V

Ryzen 7 1800X
100% reach 3.8GHz (assumed)
97% reach 3.9GHz @ 1.376V
67% reach 4.0GHz @ 1.408V
20% reach 4.1GHz @ 1.440V

Seems quite different from the results posted by OC.Jagatreview.com, unless I'm looking at something wrong.

Possibly because they only tested ten samples?

 

[TheMorningStar]

They should do very well in the server segment with the SMT and TDP advantages we are seeing over Intel with the consumer range. Much more important they are stable, though. I'm guessing they will have a similar price advantage, also. I wonder what clocks they can hit on so many cores.

If AMD can get some major SC and server wins with that,that would really turn the company around.

IIRC the default "balanced" power mode runs the CPU between 5%-100% and the "high performance" mode is just %100. From what I've read this matters quite a bit in Windows 8/10 because it's the CPU driver that enables the O/S to tell the CPU when performance is needed and as Ryzen doesn't have one yet it isn't being told what to do.
