255 tdp? How in the hell are they cooling that heat beast? Custom water-cooling required to keep it under 80' c at full load?

AMD fanboy. Intel didn't lose core war! WTF they did release 8/16 CPU which obliterates AMD CPU. And yet AMD hasn't released 7nm CPU yet, fanboy.

9900K: £500 but 25% faster (in synthetic benchmarks)!
2700X: £300 (comes with cooler) :clap: and you can put Zen2 in it in a few months and likely beat the 9900K in everything*

Huh, you could buy a 1920X and X399 Motherboard for the price of a 9900K (here in UK).

*except 720p ultra low (ini tweaked no shadows), the 9900K still gets 12% more FPS here

This is not just an overclocked i9-9940X. But obviously it's binned, like all microchips are, what you guys mean is it's a higher bin than i9-9940X, "cherry-picked" or "golden samples" if you will.

I do think Intel is pushing it too far here, both because 255W TDP is getting into a territory it's hard to cool without massive cooling, and secondly because they can't supply enough of these.

But I do like the idea behind the product, a HEDT CPU which have as many fast cores as possible, rather than just as many cores as possible by sacrificing a bit of core speed. So I think a HEDT CPU with as many fast cores as possible (and keeping TDP at ~200W) would be a good complement to HEDT CPUs with many more cores.

When it comes to workstation use, the best choice is not as simple as the highest core count etc., it really comes down to the tasks the machine will be running. People commonly think it comes down to multithreading or not, but in reality many heavily multithreaded workloads are sensitive to core speed. There are async multithreaded workloads, where worker threads are basically independent and can scale those workloads almost linearly until you run out of cores or hit a bottleneck. Many typical server loads fall into this category, but also larger batches of rendering or video encoding. For such workloads it's fine to sacrifice core speed, because what matters is total throughput. On the other hand there are many workloads which are synchronized, and while they still benefit from more cores, the synchronization overhead grows quickly, so more core speed is required to achieve good scaling.

While the current HEDT lineup is of course generally good, it's still not good enough to convince me to pull the trigger for my particular mix of development and CAD/modeling needs. And I have worked on Skylake-X, so I know how much better than its predecessors it is. So for me I would probably have to wait longer, until Ice Lake-X/SP arrives in 2020 :(, and then go for the CPU with the highest number of fast cores.

Most people use OEM PCs so I literally have no idea what you mean by "widely available".
As I've said, there are rumors about this chip being an exclusive. The rumors dating from a couple of weeks ago claimed it will only be available through selected system builders and through auction(!). I really hope these rumors are untrue. Launching products and sending them to reviewers is a bad thing if the customers can't buy the thing, regardless of how good/bad it may be. One example of this would be the i7-8086K, a perfectly fine product, except that it was not really available.

255 tdp? How in the hell are they cooling that heat beast? Custom water-cooling required to keep it under 80' c at full load?
It is certainly pushing a territory where things get really hot, especially if you're going to run this for hours of load at the time. But the biggest problem will probably be airflow in the case, rather than the CPU cooler itself.

But still remember that GPUs manage to do 250-300W with less optimal airflow, but are not completely silent though.

Informative post, thanks. Would you not be able to buy something like a 9980XE and manually overclock it to 4.6 ? With a decent AIO it would be okay I think.

I appreciate that. :)

Well, for a workstation lasting ~5 years of heavy use, overclocking is out of the question. I'm already worried that a cherry-picked CPU pushing it this far like the claimed i9-9990XE would even be risky at stock, so I wouldn't dare to buy it for that reason.

And watercooling only solves the problem of moving heat from the CPU and into the case. Most cases will be a bottleneck long before a decent air cooler (like Noctua NH-U14S) will be a problem. For watercooling to have real potential, I would need one of those special cases with a side-vent for radiators or similar. But my days of watercooling and overclocking are done. I do chuckle though when I see the kids these days building PCs with giant radiators and practically no airflow.:rolleyes:

Sure dude, sure.
Did you check my specs ? I'm using Intel/Nvidia computer.

And you're dead wrong.
Threadripper 2990WX or Epyc 7501, 7551 or 7561 have 32 cores, 64 threads, while intel tops up at 28.

And AMD already has working and demonstrated EPYC next gen 64-core CPU's (7nm chiplets), will launch very soon.
Intel has absolutely nothing to respond to that, not even if they do that glued 28+28 chip, that's still a lose in the "cores war".
But they have the clocks advantage... for now.

I'd be rather surprised if an AIO would actually allow it to get that far.. I'm not sure what those things can handle but I'd have thought you'd have needed a custom loop or something to that effect to get it that fast?

Having had a quick look on a AIO's tech page here I couldn't see anything that pointed out TDP handling at all, unless I'm just blind....

Yes but 9980XE with 8 more threads at , like 4.6-4.8 GHz will still be faster in multicore workloads than this at 5 Ghz all core, can it even reach that though? I just dont see the point.
If you're buying this CPU, it's not for multicore, because AMD has that segment sewn up with TR.

255 Watt TDP? What is this, a freaking Bulldozer?!
HAHAHA you didn't read AnandTech's review of the Xeon W-3175X did you? Here's a choice quote:

Ian Cutress said:
At 4.3 GHz, we were hitting almost 600W peak load (confirmed by wall meter), which is the limit of the cooling setup provided.

...

We took some of our benchmark values for power and frequency, extrapolated them with a power curve, and we estimate that at 5.0 GHz, this chip is likely to be drawing in excess of 900W, perhaps as high as 1200W. Yes, Intel really did need that 1700W water chiller.
Over 1kW for a single CPU. Not the system as a whole, just the CPU.

Extrapolated, but still... 600 off the wall is insane. I thought my 3930k overclocked was hungry. Someone needs to tell Intel to never go full retard.

What would be really funny is if that actually happened somewhere.

To be fair, 14 core hyperthreaded extreme edition CPU running at 4ghz, boosting to 5.1ghz. Just throwing it out there..

Nope, it lacks a sufficient amount of 9's and its not over 9000 :oops:
Doesn't need any of that, it has the "Xeon" in the name.

It has the same specs as a 9940X, except that its clock speeds are higher. So, yeah, it is a factory overclocked 9940X.

I did not mean any 9940X can OC to these speeds reliably (but with a potent cooling solution as would be needed for 9990XE anyway, I believe most 9940X's can match 9990XE clocks), hence the "value" this 9990XE brings: a guaranteed high clocks on a 14-core chip, AND THAT IS IT.

A 9940X is a 165W part, this is 255W. I bet that if one can manually OC many (say 25) 9940X's, and compare the power utilization and temperatures on 25 other 9990XEs, the differences would be statistically insignificant.

I see some suffering for Intel boards in the future right along with the bitching over how hot it gets and that this new chip killed someone's setup.... Gonna happen at some point.
Shoe is on the other foot now Intel fans.

Meh just wait for Ice Lake with the IPC increase. Nvidia 7nm will be out in 2020 as well. 2019 looks like a crap year.

This just in:

Intel Next-Generation HEVPD (high-end very-pricey desktop) CPU, code-named "Power-Lake" is fast, 5.5Ghz all-core turbo.
Unfortunately every buyer will need a lake + hydroelectric power plant* to run it, and the Multi-Jigawattz chiller it comes bundled with. (Flux capacitor optional, for the 9999X9X999XX version)

*If not feeling that green, a nuclear reactor will do as well.

TBH those TR4 air coolers that released with second gen Threadripper does a respectable job at cooling the CPU.
As long as you dont try to manually push max OC on a 2990WX.

Even with 4 less cores the TDP went up by 50% and they are usually pretty liberal with these ratings. That 14nm process is at it's absolute limit.
pretty impressive how far they pushed it, 700mm sqaured dies and most can hit 4.5+ghz
