1.9v holy shit.

lol...That would be intense.  CPUz is misreporting.  Look in the hwinfo window...it is 1.285v

Haha...I like to think this thread has been a good representation of what a 7820x is capable of, and also that it can be very effectively cooled with a AIO cooler.  Plus...It is simply the fastest 8 core processor in the world.

Indeed. It is good information for someone thinking of buying one. I'm sure there are a couple of people

This is pretty surprising. Look at the difference lowering mesh voltage by .033v (still at 3200MHz) and turning down LLC one notch made in temps. All other setting are the same. As you can see, the core voltage is unchanged, and comparing the average and peak watts, they are almost identical ~1% lower. But look at those temps! Max and average both dropped by 7c. I really did not think the mesh voltage affected temps this much.

Would be interesting to see the two changes separately, but you've given me something to look at on the weekend. What was your all core active clock during that testing?

 

I have to say I don't understand voltages on Skylake-X, or maybe it is my mobo... for example, at stock I get something around 0.9xxv in bios, and 1.1xxv in hwinfo64 and XTU. I suspect the latter is more correct, and the bios might be reporting something else. Still, with my sample 1.25 windows volts got me 4.8, and 1.35 got 4.9 GHz stable for a run of GTA V, although I didn't investigate in depth yet.

The more I use this platform, the more I get frustrated with the original reviews, both in print and YouTube.

All of the CPU and Temp issues were caused by these guys never bothering to set a reasonable AVX offset. I mean 4.5GHz+ of AVX on 8+ cores is an insane demand...no VRM cooling or soldering was going to help that. With the AVX offset to limit these chips to ~4.3GHz during AVX instructions CPU Temps and VRM temps are not really an issue. Only allowing these chips to run 4.3GHz of full blown AVX is still faster AVX processing than anything on the market.

The memory latency with a little teaking, while still not up to 7700k level, can get to around 72ns Memory and 16ns L3...paired super high bandwidth.

Not to mention that 4.8GHz+ on 8 cores at the kind of IPC this chips have is wickedly fast. Literally like two 7700ks.

I really really wish I could benchmark my machine the way it is currently setup against a 7700k in gaming. If anyone has a 7700k @ ~4.8GHZ with a 1080ti (at stock clock) and knows of some gaming benchmarks we can run, hit me up and we can compare. I bet performance is pretty close.

@done12many2 has a 7700K (that can do 5.3GHz) and 2 1080 Tis.

Hmmm...What games have good built in benchmarking?

GTA V, Tomb Raider, Rise of the Tomb Raider and Dirt off the top of my head.

Unfortunately, my 7700k is paired with the 1080 SLI and the 5960x is paired with the 1080 Ti SLI. 

 

I'd swap them in a heartbeat to help, but water. Lots of fucking water.

I work as an export manager for shoes, belts and other fashion related stuff, I go to a lot of factories daily and in of them the marketing director thing who's really friend with my boss needed 2 new computers for their marketing people and I managed to sell the 2 rigs to them.

 

New rig's going to be the i7 8700k + Xp [:

[TahoeDust]

I am sure someone on here has a 7700k and 1080 ti and would like to compare gaming benchmarks with me.

Nice work!  Ready to move stuff at any time.  I like it.

Very surprised to here that.  I expected you to go Ryzen for sure.

Really?

Spoiler

I also want the best....... best value, which more people should start caring for too, would turn the market better for sure.... when you're dealing with 100% price increase like the 1950x to 7980xe for 15~20% increase in performance I really find ludicrous there's people so stubborn to go like that... "BEST OR NUTHING" usually people like that are the ones that don't even use the PC to its full potential also 

That's not a value minded decision. You're paying 100% more to get the Titan Xp for 5% better performance than a 1080 Ti.

The thing is, from my experience Titan cards are very easy to sell in the brazilian used market, if well priced you can re-sale them in a click, for real so when Volta arrives I believe I'll have no issue selling it for enough money to make the whole experience worth it and then grab a Volta Titan X [:

 

We only live once any ways.

Naah my brother already made the honour to support AMD getting his 1800x, myself despite still indeed thinking AMD has the best HEDT at the moment I have no need for all that computing power, the 8700k will fit my needs like a glove, and as much as I bashed Intel lately here at the forum I still prefer them for my personal machines

I wasn't going to lose the opportunity, That is the fun right? put together something whenever the opportunity arrives, besides it was time to change already, one of the old Titans wasn't exactly in good aesthetically conditions

 

 

Can't wait for the new one to arrive, I already bought it but since it was importation from the US it probably only going to arrive here by the time Coffee Lake released, I'll keep you guys enthusiasts updated though, cheers.

But that still doesn't justify spending 2x more for 5% better performance. You said it yourself.

Unless you changed your mind

Factoring your ability to resell is a real thing so that makes sense.

Yeah, you've bashed Intel really good lately.  I was going to comment on the fact that you only buy Intel, but you covered that already.  

 

Once the equivalent core count parts arrive, there's no doubt that Intel will continue the trend of outperforming the equivalent core count AMD part, but that will be in performance only.  Value is what AMD has always specialized in and there's nothing wrong with that.  

 

Intel = high end performance in all categories, but costs a great deal more

AMD= good performance in most categories, but saves you a boatload of money.

Yeah, that old Titan seems to have been drug down a dirt road.

Looking forward to it.  If the 8700k ends up clocking anywhere close to the speeds of the 7700k in OCs, it's going to be a MONSTER!

Why? If it applies to CPUs and Intel it should apply to GPUs and Nvidia.
