At first I was like "wow they really took a big performance leap compared to the 6950X" until I realized it has a 500MHz gain and the hefty wattage.

According to a review by Bit-Tech, it seems there's up-to a ~10% improvement clock-per-clock.

Hmm building a pc for a friend soon and I was waiting to see how the 6 core is on these new chips but I think I will build him a ryzen build still.

So you're basically going to have to delid that £1000 CPU if you want any decent OCing headroom out of it without it cooking itself...

Where are you seeing temps? i've let to find any review that talks about temps, just that they reach 4.6/4.7ghz on them... with fine tuning maybe you could hit 4.7ghz, but these were always going to run hot they always do.

Performance jump seems to be about 5-10% when you take into account the extra 500mhz on the core clock and depending on the program being used, which i guess was expected.

Look forward to seeing your view HH, as well as the upcoming review of threadripper to see how AMD's chips will hold up

EDIT: Nevermind found a page about temps, 100 Degrees on LCS with the 4.7ghz OC :/

Intel's OC headroom has been crap on all the chips with the TIM rather than solder. Run very hot. Delidding is the only way to get decent temps out of 'em.

Yeah, just seen a guy push it to 5ghz delidding it getting from what i saw around 85-90 degrees on a corsair AIO

From what I've experience deus ex manking dividednis basicially exclusivdly gpu taxing....I would love to see one of the dragon age games benched bencause they always scalednextremely well with core count.

All these synthetic benches mean nothing to me.

Yeah, the numbers are quite impressive, for both the cinebench (good) and the wattage / temps (bad). Seems they've gone all out maximizing performance, at the cost of power efficiency.

This is what happens when Intel ignores the EU those pesky NDA's just don't apply.

I see another review from bit-tech as well. The 6950X does win in a few cases which is odd I wonder if Intels L3 reduction and more L2 cache is hurting performance in a few cases.

I agree that intel should really be using solder on all their chips and they should have something more high end for their IHS than nickel plated copper alloy. Their big chips used solder for the last few years and they were rated Conflict Mineral Free, so sourcing Conflict Free solder shouldnt be that hard.

Diamond metal matrix composite IHS have existed for years, and could be a differentiating selling point for their high end chips as well.

That would eliminate the need to delid and probably to liquid cool as well, give a big boot to overclocking and justify their margins.

Well, right now they can charge whatever they want since AMD currently doesn't have a competing product, and because they know people are going to buy it. What will be laughable is if Intel keeps this price point after AMD releases their 16 core for an equal or lower price.

I can't believe that anyone can't wait two weeks to get what looks to be a product which looks to be at least 1.5x perf/dollar.

This is not the old days where they were really alone, they aren't any more.

Being devil's advocate: There's a good chance TR won't overclock as high; the only attraction of i9 is how high you can push it. This is of course assuming anyone is willing to deal with the expense of a high-end cooling system and a higher electric bill.

But take a look around the internet and you'll find plenty of people drooling over i9, while not even aware TR is a thing. Look at forums discussing i9 or TR, and you'll find people strongly defending i9 or have low hopes for TR. Most people don't even have a realistic use for an i9, yet so many people still want one. It doesn't have to make sense - people will still buy it. That's what brand loyalty and envy accomplishes.

I'm certain it won't OC as high.

On the other hand if anyone gets a $1000 ten-core to game, they need a brain transplant. So if you aren't only gaming, why not get the 16/32 CPU that will destroy this one at $849? What is the meaning of the existence of this CPU?

I found the leaked price for the EPYC 24/48 1P CPU very interesting at about >$1,000

Sure stock it is only up to 3GHz I think it was, but that is a Whole lot of cores for the right task !!!

Hope it is also unlocked, would love to try this on my oversize custom loop and see what it is capable of

The 7800x and 7820x are going to be the only CPU's with any simblance of value in this line.

Just read the Hexus and Bit Tech reviews and the conclusion is that the 7900X seems to be a great cpu with amazing performance and a very good overclocker, needing even less voltage than my 7600K to hit similar speeds!... And it even can reach 5.0Ghz for the guys brave enough to dellid the cpu... Seriously Intel, you couldn´t solder a 1000€ cpu???
The problems, besides the stupid price, are the thermals and the power consumption that are very high!!!

Now, who´s brave enough to fork 1000€ for this thing???...

P.S. I feel sorry for Hilbert, seeing other sites doing reviews of Intel cpus and the only thing he can dos is talk about them... But kudos for the fair play Hilbert!

I think TR will overclock as high as Ryzen 7 (so 4.1 GHz tops). In other words, I don't expect crazy overclocks with it - as long as it performs about twice as fast as Ryzen 7 in multithreaded tasks, I'll be happy.

I disagree about the awareness of TR. There was a YouTube video on Gamers Nexus about how Intel's X299 platform wasn't getting much attention compared to AMD's X399 (I think it was posted about a week ago). I would say people are far more interested in TR than in i9, at least among the knowledgeable, enthusiast crowd (who watch tech tubers). The average person might not care as much, but the average person isn't a HEDT customer.

So which processor do you guys think will be the better gaming solution for 3-5 year build this year? Hitman and Deus ex isn't really much to go on. I'd like to see some Frostbite, UE4 and Cryengine 5 benchmarks.

I definitely plan to upgrade this year but a little concerned over the i7 X's wattage since I'm a SFF user.

You already have the fastest.... i7-7740K will overclock to 7.5GHz I heard though...

And even for these we'll be probably paying $200 extra compared to the closest Threadripper. It seems that AMD will position the lowest TR at $400 only and move the whole line accordingly. Their EPYC part with 8 cores is at $400.

Intel is still +50% more expensive, but at least this time the final price is closer to something remotely reasonable. They will have a huge issue if TR clocks higher as rumored, although I have to say I don't believe that rumor. Even for pure HEDT again, the 7820x will be competing with the 12 core TR.
