i7 4790K ES Review: mildly disappointing?

Recommended Posts

First off, read all about it here:

http://hexus.net/tech/reviews/cpu/70473-intel-core-i7-4790k-devils-canyon-22nm-haswell/

 

Highlights:

Base clock 4Ghz

Will work in Z87 mobos (firmware upgraded)

 

Lowlights:

Non-OC stress loads run at 88c

1.152v base voltage (VID?)

New TIM is NOT solder

OC ability is so weak they didn't bother with it

 

IMO:

Essentially a rebadged 4770K sporting a clock and voltage boost, and somewhat better packaging.

I was once excited, but considering my stock TIM 4770K runs stable at 4.5Ghz at 1.21v (HT on, 1.19v HT off) and stays under 90c with my air cooler, I doubt the 4790K is worth my while.  But for those yet upgrade (or have a really lousy 4770K), getting a 4790K is a no brainer.

 

BUT...this is an engineering sample (ES) so I can't say anything for certain.

When I read that it would have a silicon-based TIM and not fluxless solder, I had the feeling that it wouldn't go well. This confirmed my fears.

 

I think that we should accept it now, as long as AMD keep being uncompetitive, Intel will keep crippling the consumer parts. If you want fluxless solder and all features enabled, you'll have to go with the enthusiast parts (Ivy Bridge-E or the upcoming Haswell-E).

 

Please AMD, make your 2015 architecture good.

Devil's Canyon is supposed to be for enthusiasts.

 

Not really, Devil's Canyon CPUs are the unlocked variants of Haswell Refresh. Like the 4770K and the 4670K, they're consumer models.

 

Haswell-E CPUs will be the enthusiast models, namely the 5820K, the 5930K and the 5960X.

Sigh. I guess this isn't it. We need something clockable to 5.0 Ghz.

 

Yes, we do need that, but a stock 4Ghz chip capable of Turbo'ing to 4.4Ghz is a pretty big deal... seeing as clock speed matters more than just about anything else when it comes to the MSFS line. 

 

I am waiting for Broadwell, but this is great news to see clock speeds continuing to trend upwards.

Non-OC temps at 88C???  Holy ****.  :huh: :blink: :wacko:

I have a feeling thats with a crappy stock cooler a h110 would bring that down quite a bit

Its to early to judge the 4790k on a ES sample ,wait to we get some more rewiews .

Doing a new build , so going to wait to see how these go .

What about the lapping thing. & changing the paste and using Coollaboratory Liquid Ultra

Seen others do this to there cpu,s

Why, did you expect anything different? Did you really think that they would redesign the chip?

 

Disappointing? Only for overclockers, for anyone else it's quite an improvement going from 3.5Ghz to 4, that's about a 15% gain, even better for people like me who have skipped the 4770K.

 

And last.... you're making conclusion on a single site, based on a none-retail version of the CPU.

The bad overclockability is the fault of the TIM, not the chip itself. If they used fluxless solder (as it was expected), it would overclock fine.

But gentlemen... if it's still TIM, think what you can achieve if you delid it!!!!

 

New TIM is NOT solder

 

 

 

Don't forget, fluxless solder isn't truly "solder" either. It's a conductive epoxy... glue in other words. Better than TIM probably, but still just glue.

Seems you are responding only to the title of my post.  All your comments are touched upon in my post.

 

As for redesign, BTW I did expect something considering they designated it "Devil's Canyon" rather than keeping the name Haswell.

That's the problem; you've still got to delid the CPU to achieve its full potential, taking a huge risk.

I doubt they want it to be a great overclocker, think about it Haswell is a great CPU but if people could hit 5-6ghz on it no one would buy a new cpu for many many years. Im coming from an AMD chip so if I can run the same 4.5ghz on my 4790k that I hit on my FX8350 I'll still be miles ahead.

It was tongue in cheek, but...

 

When you consider that the fluxless solder alternative used these days is actually just a conductive glue, and somewhat inferior to the true hot solder used in years gone by... delliding probably achieves better results.

wow another potential wait?

 

I have an i7-920 which I can barely get to 3.2 ghz.  I was (probably will still) going to upgrade it all in September...

That surprises me, my old i7 920 did 4GHz easy, with an NH-D14. I sold it to a friend who is still at 4Ghz with an Archon.

 

I'll gladly ask him for a copy of the settings if you like, as I no longer have them.

 

Of course you may have just been out of luck with the silicone lottery.

Maybe that was the inspiration for the designation "Devil's Canyon". :lol:

I've been running an 860 at 4GHz for 4 straight years - you must have gotten a really badly binned chip.

Agree, he may have come across badly in the silicone lottery.

 

Or... his settings are dodgy.

 

Or cooling.

Sigh. I guess this isn't it. We need something clockable to 5.0 Ghz.

If you're lucky in the chip lottery, you might already be pretty close! My 3770k is able to crack 5.0 with 1.395v VCore (and a little overvolted PLL). I haven't delidded it, nor lapped it. I fitted it with the biggest Corsair water cooler, and voila. Runs @ +65->70 C in a +22C room max in FSX. Tempratures are a bit alarming in Prime 95, I must admit, but it has yet to CTD FSX (no BSOD either). 

 

That said - my first 3770k, was nowhere near as stable as this one. To punch through the 5ghz barrier, it required almost 1.510 volts Vcore. The Corsair cooler didn't stand a chance at that voltage. Delidded the CPU, and fitted it with some new thermal paste (the old one was rubbish - all hard.), and the temprature dropped somewath, but it was to unstable. It remained stable at around 4.2 ghz, but filled up the event log with "hardware error" messages, and crashed FSX continuously. (It now runs at stock setup, rock stable, in a Ubuntu Server I'm using to run a couple of virtual Windows 7 computers, running ASN, Aivlasoft etc).  

 

I've done all my clocking (although removing turbo boost, HT and everything else smelling of power saving options in BIOS) in the software tweaking stuff bundled with the motherboard. I only apply the overclock when running FSX, P3Dv2.2 or XP10. 

 

Best regards,
