To be Honest, i'm not really impressed. Anandtech also is pretty biased, compared to the Ryzen Launch, where everything was tested right out of the box, with all of ryzens "flaws" in the beginning.

But, Performance wise...nearly 180 Watt more Power Draw, than the R7 1800X and it has not obliterated Ryzen. Also: OC3D's Ryzen results are the ones from the launch of Ryzen, without optimisations.

 

Bit Disappointing.

Where did you get 180W MORE than an 1800x????

The X299 CPUs don't even go over 140W, so you're saying the 1800X uses negative 40W?

u w0t m8???

the Haswell-E goes 200W+

the Broadwell-E goes  berserk 250W+

when overclocked

It's for overclocked chips

Oh you're talking about OC?

Only looks like 80W to me, not 180W.....

OC power consumption also completely depends on the silicon lottery and how much voltage you pump through the CPU.

same difference and none of those chips stop at their TDP...

?!?

Can you try writing that sentence again?

 

The difference between an overclock 7820X and 1800x is 86W, not 180W.

OC power will also depend on the silicon lottery.

[TahoeDust]

So...the 7820x is more expensive, takes more power, and runs hotter....but clocks higher and performs better.  Is this not what everyone expected?

*looks at stock 4790K consuming 114W in AVX loads*

People are dissapointed because x299 isn't more efficient than Ryzen, nor is it cost efficient; making it less appealing than some wanted it to be.

Did people really expect intel to come out with a "cost efficient" X-series line of processors?

Some..:)

 

Maybe cost competitive will be a better term?

Well when Adnantech says "has a cost advantage"... yes... they're so used to damn overpriced parts that an 1000$ 10 cores is for them a reeally good price because it used to be 1700$, while not considering we could have 14-16 cores from amd at the same price. 

(I won't trust them anymore with that kind of ridiculous reviews... you can say anything but cost advantage, and seeing the performance difference between the 1800X and the 7820X is quite similar, they cannot seriously advise to not wait a month for Threadripper to see what happens, since it could offer not that far performance for quite less with more complete platform in a small time-frame. But they seem to advise a cash grab.)

 

[kuzko]

Aouch, if I ever plan on using those chips, I better have some shares in a few solar power plants because damn those are thirsty. Also, they now get without pretty much any doubt the "heater" status that amd had a few years back.

Though, if the workload or programm used can use the insane SSSE3  and AVX512 (maybe SSE4 too?) IS then the performance would be quite good for the power consumption... if not, those cpus would be too much of a bother to buy and run...

Yep largely underwhelming, especially streaming and gaming (which lets be honest will still be the primary use case for HEDT users). Was excited for NDA lift but then the reviews with marginal gains for 2-3x the platform cost rolled in and I was just like meh...

@PCGuy_5960

LOL Intel boys love this one. They won't ever use AVX512 (because its largely found in enterprise) but they love being able to say they have it for some reason.

The 7820X is at around 400W and yes OC results are valid because the 1800X was oc'd too. The 7900X on the other hand drew so much that for some reviewers it caused a system failure. So erm yeah the even thirstier chips due later this year will be interesting  Separate PSU maybe?

That and "AVX 512" will be the new buzz words associated with why you should pay 3x the cost of a 1700 and B350 mobo for a 7820X. Almost nobody however will point out that in GN's test that is a 10 core CPU retailing at $999 USD so it will be competing against the 16 core ThreadRipper at $849 not the $280-400 8 core R7s...

Nope I don't think anyone expected that. I think most expected a market dominator in response to Ryzen and Threadripper. Just like Sandy Bridge was way back when innovation was a thing... However what they got was a slight performance bump over the R7 and kept the "Intel Tax" pricing without the justification that they used to have with X99 for example. (can't be tested against TR yet but I look forward to seeing the $849 16 core go up against the $999 10 core). I think it will take a bit of time for Intel to realise that they aren't competing against just themselves anymore.

FYI, it's not just AVX3, but AVX1 and AVX2 as well  AVX1 and 2 are used by programs like CAD and Handbrake, so it's not as uncommon as you think

But Ryzen supports those... Don't see your point there? It's only AVX512 that is missing.

Yes it does "support" them. But AVX is intentionally gimped on Ryzen. Y cruncher uses AVX:

Yep, but that's using H.264, H.265 uses AVX

I live in Israel and my house doesn't have AC, I keep one of these nearby anyway even running my 2600K at stock
