After reading the reviews, AMD has too much compromises and is inconsistent in performance in anything that's not a synthetic benchmark where even a 7800x wins more than it loses against the fastest Ryzen 1800x. Thus I preordered a 7820x and a Taichi!

That chip will be very fast even at stock settings. I hope you share some info on your temps and overclock results if you decide to overclock.

So... if threadripper looks decent I may be building my first AMD rig in a decade. Sorry Intel but I'm just not feeling it. Yeah, I'll take a hit on the IPC and clockspeed coming from a 7700k, but moar cores that run cool sure is appealing, especially if AMD is able to eek out a bit more out of the process by then.
Why not go with a Ryzen 8 core if you feel that way?

I hope some of you brave SKY-X souls start a delid overclocking results thread!

Not going to delid or even overclock my SKX parts. These are clocked fast enough at stock (and consume enough power/generate enough heat...) that I don't really feel the need.

Old "E" series processors were clocked comically low so overclocking was necessary.

I'm definitely going to be looking at feedback from users in our forums over the next few months to help make my decision and can't wait to see their reports. I can't wait to hear the reports from a delidded 7900. If it can drop the temps 15-20 degrees (might be too optimistic), I'll grab one from Silicon Lottery. I'll still wait to see if my suspicion is correct and Intel solders the 12c+ parts though.

I need something with moderate temps (no more that 80-85 under super heavy load) under a high-end AIO or air cooler. I am not building a custom loop for this. I'm probably dreaming but I hope it happens.

- CPU draws too much power
- CPU runs too hot
- For 2 more cores, you get 50% more more power draw over ryzen
- No TIM and no explanation as to why there is no TIM
- Motherboards cost too much money
- CPU is overpriced

Dropping them w/o hesitation. The only question is if I go Ryzen or Threadripper.

You don't know if all of these opinions on the Intel product line will be equally valid, or worse, on TR - because TR isn't out yet.

Coming from a 7700K I'm suspecting you'll regret it and be stuck with a much slower system. Hope I'm wrong and that'll be happy with whatever you decide buying.

If anyone runs BOINC, please let me know ambient + load temps, cooling method employed, and maximum stable OC for BOINC use (if applicable).

I want to know if there's any real OC headroom on the 10-core and 12-core parts for crunching work.

Update on Silicon Lottery (pricing).
Expect entry bins to be about 8-10% over MSRP, so yes there will be options well within that.
https://siliconlottery.com/collections/lga-2066
Not available till July 2nd. Will include 1 year warranty.

It's looking like anything over 6 cores will need custom H2O + delid for serious overclocking. I haven't done a custom loop in 10 years, wish I had the $$s, would be really fun.

You think that even with a delid, both the 7820 and 7900 will require a custom loop? I'm not going to go crazy here - I'd be happy with an all-core overclock of 4.6-4.8.

Unless some of the power numbers we've seen are off. I suppose that with a delid, if we see the same drops as with Kabylake, then a good AIO will be good for something 4.6, especially on the 8 core. A lot of the data is for the 10 core. I think there is more headroom on the top CPUs so far, it'll just take a really good mobo and custom LC to bring out their max capability, IMHO.

Toms was only able to stabilize 4.4 GHz on their 7900x with an industrial chiller (so thermals removed from the equation).

I'm waiting to see what kind of overclocks real people get.

Did they delid? Guess I'm going to have to read that review.

If anything they have pinpointed the need of delid - HUGE delta between cores and surface of heatsink and there was only so much chiller could help.

The problem with stock TIM is that cores enter thermal "runaway" - heat rises core temp, that in turn rises leak current amperage and results in even more power that needs to be dissipated. End result is CPU that is stable @4.6 and 1.2V, but is thermal throttling hard...

Actually, TOM's hit 4.8 GHz with an Alphacool Eiszeit Chiller 2000. They didn't do any delidding.
Their custom loop 'threw in the towel' at 4.6 GHz. I think if they delidded, they would have had a better result - we'll have to wait and see.
Look like max power draw was around 200W - that should be able to be cooled very well with a custom loop.

They were able to run cinebench at 4.8 but only passed stress testing at 4.4.

Power draw @ 4.8Ghz in CB 15 was 260W, with max values probably reaching 300W+ in heavy AVX loads.

Their CB 15 power/frequency curve is probably the best guideline for choosing a cooling solution for SKL-X, with CB 15 being more of a load than most apps, but still not as unrealistic as Prime 95.

I'm sorry but there are a lot of details that have already been disclosed and are known w.r.t to thread ripper. The general pricing is already known. It's nowhere as expensive as skylake. The 16 core threadripper is going to be within $1,000 and $850. Compared to the 7800x which is $1,000, it's already a far better value.
It is already known from EPYC that Threadripper will be TIM. The power profile is already generally known. The heat characteristics are also generally known w.r.t to scaled ryzen complexes. So :
- Less power draw
- Better thermal efficiency
- TIM
- Better CPU price
The only thing that isn't generally known within a good window are the mobo prices. I've been building PCs for some time. They all have been intel. I'm over the twilight years of overclocking to get better FPS.
I care about heat and I care about power draws. I don't care for the limits of clocking on 14nm as I understand the logarithmic power requirements to do so. Also, I understand the latencies of the instruction/data pipeline and understand what bottlenecks are.
I know what data flows I will be processing and Ryzen's mico-architecture are actually better suited for it and scale better.



After reading the reviews, AMD has too much compromises and is inconsistent in performance in anything that's not a synthetic benchmark where even a 7800x wins more than it loses against the fastest Ryzen 1800x. Thus I preordered a 7820x and a Taichi!
After reading deep technical details about the micro-architecture, AMD's micro-architecture is quite consistent and high performance for the work load I intend. A 7800x is a 10 core processor. Ryzen 1800x is an 8 core processor. Compared the 7820x to ryzen 1800. 7820x consumes 50% more power and subsequent heat for same points on a benchmark... Flat out raw performance mattered to me in my teens and early twenties when I was hooked to the bleeding edge of performance. Now my taste and selection is a bit more refined. I understand DRAM latencies, context switch latencies, multi-threading producer/consumer patterns, etc and understand the diminishing returns of increased clocks and subsequent power draws. Bottlenecks still exists. The nature of some of these CPUs w.r.t to real world environments is akin to sucking data through a straw. I doubt most people here have even seen a run-time profiling app on a modern game engine. You'd be shocked at the amount of stalling and latency that exists w.r.t to data access. Anywho, i'm going Ryzen or Threadripper. I have enough intel builds and gaming under my belt, I'm focused more so on economically feasible content production and power/heat efficiency and getting on board with an architecture that has bigger plans for the years ahead and will be consistent across them. If thread ripper isn't priced right, i'll ensure to drop down to ryzen and wait until it is.

I know, coming from Intel pricing, it's shocking that you can get a 16 core in that price range.
Even more shocking is the even more capable EPYC being priced even lower.

So yes, thread-ripper's general pricing is between $850-$1000.
A 16core processor.

That's what happens when you have a high yield production process and aren't price gouging your customers.
In any event, the details and release will be factual in another month or so. At that point, don't shake your head too much. It might fall off

That's EPYC, not TR. And if the latter actually does come in at that price I stand corrected and it will have a reason for being so cheap - and that won't be in its favour and it's not good yields. I'm not at all against AMD but if history, even recent history, has taught us anything... I do sincerely applaud people holding out buying SKL-X to see what TR brings; that's always a smart move, to have all the facts in

I am screen capping this post for reference in the future. EPYC is equivalent to Xeon processors. Indeed it's not threadripper. Threadrpper is a scaled down and less featured CPU complex. However, per your logic, that equates to a higher price. Great yields are factual w.r.t to AMD. The desire of AMD to disrupt intel and not price gouging its customers also contribute to lower rpice.. You're logic is literally : If I'm not being price gouged, there's something fundamental wrong. Amazing.

I'm not at all against AMD
You sure? because logic nor facts are on your side.

even recent history, has taught us anything
Yes, please detail what Ryzen has taught you.

I do sincerely applaud people holding out buying SKL-X to see what TR brings; that's always a smart move, to have all the facts in
Skylake isn't even on my radar. I've evaluated the platform and don't like its performance to price/power/thermal ratios. If threadripper disappoints, I'm falling back to Ryzen.
I already have an intel quadcore, 32GB ram, with 1070 vidya setup. I'm past my enthusiast phase. I care more for reasoned performance/price/power/thermal ratios.
Furthermore, I care for a company that is making foundational strides towards : http://developer.amd.com/resources/...hat-is-heterogeneous-system-architecture-hsa/
which AMD is doing at the micro-architectural level.

If you want a bleeding edge gaming PC that sucks down gobs of power, dumps tons of heat in your room, and don't care about price, have at it. My GPU already serves as a portable heater. I don't need another space heater.
I respect those who are in the RAW performance @ any cost phase. I respect it because I once thought this way and understand it. But, don't go beyond facts/logic to justify your position. Just state that you care most of all about raw performance and don't care about $/power/heat. If you state that and refer to the raw performance benchmarks whereby intel beats AMD, I wouldn't have a single thing I could say against it because its factual.

When you get a chance, look at the poll results.

Just a pleasant reminder from a relative nobody forum zombie that this is a Skylake-X thread, not an AMD thread so . . .

No Intel thread can exist on the planet where the AMD army doesn't come stomping in. I wonder if it's the other way around too in AMD threads...somehow I doubt it. It's becoming boring and I'll definitely refrain from engaging in any such futile discussions. Apologies for derailing folks.

I'll close my post by stating that I wish AMD was on par with Intel and that there would be one/two more equal players in the field.
