AMD Ryzen (Summit Ridge) Benchmarks Thread (use new thread)

[Timmah!]

With faster memory speeds DDR4 should perform better. At the same clock, DDR3 with its lower latency should do better.




You didn't. Exactly the opposite. If Broadwell requires 128MB of edram to match the IPC gain of Skylake, then it clearly shows that the Broadwell core brought less IPC gains to us.

Can i have some link where its quantified how much performance brings that 128MB of edram to the table?

And if games are so cache dependent, why use them as a proof of anything when talking about IPC (gains)?

Ryzen huh. Risen + Zen = Ryzen? Okay, uh, whatever.

3.4+ GHz . . . if that means 3.4 GHz base clock then that's fine too. Sure beats 3.2 GHz base clock. It also beats my running expectation of a 3.33 GHz base clock with 4 GHz turbo.

Not sure what to make of the power optimization stuff. I sure hope we can just lock in an OC and let it go instead of worrying about throttling/multiple turbo states . . .

Looks interesting, we'll see how well it does in practice. But maybe I build a custom loop for my Zen build.

So no predefined max boost. But 3.4 base is pre-Devil's Canyon stuff.

Devil's Canyon was 4 core CPU. 3.4 GHz is in the range of Broadwell-E frequencies on 8 core CPU.

Isn't that the same base clock as 6800K with 2 more cores?

True, but you can't really say if that's base or turbo though.

True.. hopefully tomorrow we find out.

Dont feed them. Just report the posts.

Doesnt say it is the base clock. Could be base, max single core turbo, or even max overclock, who knows, since they dont specify.

Could be 3.4GHz+ all core turbo depending on the thermals, power consumption, etc.

I'm sure we'll find out more tomorrow.

There's already a 3.2Ghz based 3.5Ghz turbo ES leaked, so this 3.4Ghz might likely mean base clock.

I'd guess all-core turbo before base.

 

[HurleyBird]

How close AMD's base clocks are in comparison to Intel's are likely to be far less significant than where their boost clocks lie in comparison anyway.

 

[Doom2pro]

Well don't forget that it said 3.4 PLUS. Whatever that implies.

The review is from aug 2015 and since then ddr4 prices have fallen quite a lot. At that time the comparison gave good sense. And for our purpose its perfectly fine as it shows us what ipc benefits the core gives us on the same memory type. 2.4% on ddr3 1866 cas 9.
One can say thay today ddr4 3000 is low price so the platform should be compared using that. Fine. You dont buy a cpu you buy performance but dont fool yourself thinking its solely the new ice lake giving the benefit so to speak.
The point is the ipc of the cpu have more or less stopped and we get our gain from everywhere else. Memory subsystem. More cores due to efficiency gains. Fine.
I just posted in the bf1 thread under games that people should remember to use dual channel and 1866 and up ram. We have a lot of people running single channel on eg skl i5. Go look at the new 1070 laptop review at AT. Single channel. Thats what comes on the market when focus is dead wrong.

Wrong. DDR4 3000Mhz was cheap as chips on Skylake release. I got a 3000Mhz 16GB kit for £130, not much of a premium over DDR3.

I hope to goodness the OP is a lie. I have no plans to buy any new Intel technology, because they serve it out in teaspoons.I'm just tired of it.

Also all the newer stuff post Ivy-Bridge is very fragile and prone to failure.

CPU's are supposed to be installed by a competent professional. Just because it's so incredibly easy to do it yourself doesn't excuse you for fat fingering or dropping them. It really is quite difficult to damage Intel CPU's, due to lack of pins and solid IHS.

 

[raghu78]

wow if Zen clocks at 3.4 Ghz base then I think its impressive. Now we need to see what the actual clocks are for base, all core turbo and max turbo. I am hoping Zen really brings back competition to the CPU market. Its been a decade of Intel domination and quite boring.

Smart Fetch - by Local cache looks like they mean L3 of one CCx - would this be aimed at mitigating CCx-CCx penalty? Wonder what OS awareness this needs (to keep threads on a CCx)

Welcome back banned Troll ConcernedCitizen. Was your ban satisfactory?

FX-9590 was 4.7GHz base.

 

[bystander36]

True, but you can't really say if that's base or turbo though.

My interpretation of 3.4+Ghz, is 3.4 is the base, and above is based on silicon lottery and cooling.

 

[EightySix Four]

The leaks are saying it has auto-overclocking with no predefined "top" boost based on cooling capacity, LN2 was mentioned so it appears it can go balls to the wall on its own without user intervention.

 

[majord]

There will be some limit, but ultimatly it's saying there will be an extra dimension to the binning process, that being Core temp. My guess some sort of Lookup table based on process behavior on top of standard binning technique. Because of that I'd also guess it would be pretty conservative.

My interpretation of 3.4+Ghz, is 3.4 is the base, and above is based on silicon lottery and cooling.

No, You'll have a Base, a Max precision Boost, and then the Temperature based XFR.

"3.4Ghz+" could however mean 3.4 boost + XFR which would be a bit disappointing.
