It's surprising how much performance they've managed to gain despite this only being a refinement of the original. The improved multicore turbo, memory latency, and the clockspeed bump make this a pretty respectable stop-gap until Zen 2 arrives next year.

IF it arrives next year. Silicon manufacturers are having difficulties with 7 nm.

I think they are based on a more modern technology, 12 vs 14 nm, which brings all kinds of advantages.

Ah, yeah. I'd forgotten how difficult getting to 14nm for Skylake was, and then after that the extra year being added to Intel's schedule where 'tick, tock' became 'process, architecture, optimisation'. Surely things are only going to become even more difficult from here.

Thanks for this link, I was considering a 2700x build based on the press at AnandTech and Tom's Hardware. Unfortunately both those sites don't really review for our specific kind of workload and Techreport's runs here confirmed my suspicions.

I'm going to wait to see what Intel releases around Q4. I'm hoping for more hardware mitigation dedicated to spectre and meldown variants along with a competitive bump caused by AMD's current release. It's good to see competition in the desktop CPU sector again!

VI Bench results are really bad, I wonder why.

Likely due to the differing design goals of Intel and AMD, at least since Ryzen was announced.

AnandTech sums it up pretty well IMO:

However, certain metrics will still run true as to the launch last year:

* Intel is expected to have a frequency and IPC advantage
* AMD’s counter is to come close on frequency and offer more cores at the same price

It is easy for AMD to wave the multi-threaded crown with its internal testing, however the single thread performance is still a little behind. A number of the new features with the Ryzen 2000-series are designed to help this: slightly higher IPC, higher frequencies, a higher TDP, and a better dynamic frequency boost model.

VI bench is all about instructions per cycle and is a real-time bound problem. You can't easily parallelize this kind of problem and it's why Intel still shines here.

I hope AMD decides this is an area worth attacking for their next iteration.

The new 2600X must be excellent value. Judging from early benchmark results, it is superior to every gen1 Ryzen (except the 1800X, although the difference is very small), despite having 2 cores fewer than the 1700 and 1700X.
And it seems they all ship with a powerful stock cooler now, which adds even more to the value.

Lesha · Post by **Lesha** » Tue Apr 24, 2018 5:20 pm

I think I will go with 2600 as I have a pretty good cooler already, a Noctua NH-D15. 2600 needs 1.25 V for getting to 4.1 GHz so that is what I am aiming for - low power consumption, low temps and a quiet cooler.

fluffy_little_something · Tue Apr 24, 2018 5:23 pm

Seems they also have a mighty 2800X, but for strategic reasons they are not offering it yet for the time being.

Logically it must be more powerful than the 2700X, which is already a beast

Extreme overclockers have already pushed it beyond 6 GHz on all cores

Jim Keller, a key figure in AMD's revival, has been hired by Intel. There doesn't seem to be much loyalty in that industry

Fast RAM is Ryzen best friend.

The 2700X has left behind the 8-core Threadripper and is actually closing in on the 12-core Threadripper

For half the price, I might add

"I ran into some failures using PB2 and I was able to track these down to NOT being PB2's
issue, but rather a Windows Bug. We are using the latest version of Windows 10 64-bit and
all its updates that were available on April 17th. We knew we were going to be doing a lot
of testing, so we froze our OS updates at that point. What I was finding is that I would get
these random power-downs using Cinebench, HWinfo64, and CPUz at the same time. I could not
replicate the error without these three programs running simultaneously. At time I just
assumed that I was beating on the CPU hard enough to make it fail, until it went into a hard
power-down while sitting idle at the desktop, and I could replicate this issue at idle.
Talking with AMD and ASUS about this, they asked me to work through the other power profiles
we were not using. We use "High Power" for all our testing here. I moved to the Balanced
profile, and it still happened. I then moved to the Ryzen Balanced profile, and it was still
happening. Once I moved back to the High Performance profile again, I could not repeat the
error. I could not replicate the error in Balanced or Ryzen Balanced either. ASUS let me
know that there has been a Windows bug identified with this issue. The current solution to
the issues seems to be to switch power profiles one or two times and it will correct itself.
So if you are having some odd shutdowns, do not assume it is anything hardware or heat
related."

A 32-core, 64-thread Threadripper processor will be launched soon, the 2990X.

Sounds great on paper but is the windows 10 bug fixed yet which makes it unstable when more than 14 cores are used?

It works fine in windows 8.1 so why did they cripple windows 10 this way?
