7900X Coming In Hot?!

So 6% more power draw than Ryzen for far more single core performance and 2 more cores.

 

Win.

Low OC on the 7900X (And about the lowest power draw reading we've seen) and a really high OC on the 1800X. So that's not too surprising.  I'm not sure what OCCT Linpack does for testing power draw, though.

Just for fun, they should downclock it to about 3.8 and disable 2 cores to match a 4.1 1800X and see the power consumption difference.  That would give a "shut the fuck up" data point.

Seems these kind of tests are all over the place. Techspot/Hardware Unboxed reviews the 7900X, when OC to 4.6GHz with 1.2v, system power draw hits 402W.

 

What's going on?

Not really. We'd just mock the person for being an idiotic fan-boy, as that's actually what is going on.

 

It appears OCCT is a decent test for stability, but it's got nothing on Prime95 for trashing the cores.  So, take it for what it is.  (Which I think it's actually the AVX that's driving a lot of the heat issues.)

A large delta in chip performance. Note Steve did not get his chip from Intel so it won't be a golden chip

Workload matters for this stuff. AVX being the really power hungry calculations right now.

My thoughts exactly. I'll take that trade off anytime!!

Cinebench R15 Multi-core is generally 2150-2200 on a "stock" 7900X. 2400 under all-core OC.  I imagine someone is going to get 2500 posted by next week.

 

Which brings up an interesting discussion about the actual performance uplift from a heavy OC vs the extra power usage/heat generation.

The 7800X seems really efficient TBH  It doesn't draw a lot of power which means that it should run pretty cool as well. I am seriously considering upgrading to the 7800X

Based on you not having an AIO i'd say thats smart  Also OP is updated.

This is a little too funny not to share.  Under an OC to 4.5 Ghz on the 7900X, 6600k & 6700k, they post a Cinebench R15 Single-core score of 195, 194 & 195 (respectively).  Can't complain it isn't a Skylake score, haha.

I will probably get the 7800X or the 7820X, but I will wait for Threadripper before I decide (ofc)

Unless you need the I/O, I'd really recommend waiting for Coffee Lake for a 6c/12t Intel CPU. It really looks like it'll be on the 2nd revision of the 14nm process.

If you are a gamer TR won't be for you. It won't clock above Ryzen so unless you have some heavy workstation tasks to do TR isn't the best purchase. Looking forward to seeing a 16 core desktop CPU in workstation tasks though

But he won't like going from HEDT to mainstream peasantry like us LGA115X and AM4 peasants

The 7820X not having the full PCIe lanes would, if I was in the market for a HEDT right now, really drive me up a wall. That's probably the better CPU on the X299 stack, but that's a huge price delta to get full access.

Announcement is August or September.  Not conjecture, as it was on Intel's roadmap giving to financial analysts in May. It'll be out this year, but we don't know exactly when. October?

Yeah, but 10/12 cores means that you can record gameplay, render videos, play games all at the same time without losing FPS. Pretty cool stuff

Don't really need all that IO

Z370 Coffeelake-S parts will be out this year, which includes the 6c/12t top SKU.  It'll be on 14nm++.

 

The 300-series, "mainstream" motherboards & parts will be something like late Q1/early Q2 2018.  

 

Cannonlake, the 10nm parts, are coming to Mobile *only*.  Intel has had problems with 10nm, but everyone has.

I heard latest leaks were that is was delayed feb 2018?

The whole "product stack" is going to stretch out well into 2018. The Z370 / k SKU parts are this year.
