Who's skipping Haswell-e and Broadwell-e?

[Arachnotronic]

Interesting, but will it even be called Icelake?

Typically it's 2 generations with some common suffix.

Sandy Bridge, Ivy Bridge
Haswell, Broadwell
Skylake, Cannonlake
Successor, Processor

It's Icelake. The codename, along with Cannonlake, has appeared in numerous Intel employee LinkedIn profiles.

Still running a Conroe circa 2006 - waiting patiently for skylake

 

[BD2003]

Unless you're interested in the integrated GPU, what are you waiting for? Broadwell is what, 5% better IPC than Haswell? skylake probably another 5%? X99 and DDR4 will be with us for a long time and hex cores are finally cheap. If that's not interesting enough to upgrade from your current setup, the HEDT platform won't be interesting to you for the better part of a decade. Intel is underclocking Has-E by a huge degree so they have room for frequency bumps to make upgrades more interesting to the non-OCers over the next few years, but it's a piece of cake to get 4ghz+ out of even a 5960X with relatively low voltage and non-exotic cooling. Taking OCing into account it's unlikely that performance will really improve for a very long time, the boards are ready for the next decade of memory, 16x PCI 3.0 is nowhere near tapped out and they have more than enough PCIE lanes, SATA-E and m.2 slots for NVME SSDs up to 32gb/s....so why not get in now?

I'm definitely skipping it. I just don't see that big of a performance difference since my main computer usage is gaming, other than ordinary things.

If, over the 8 months or so, the overclocking ranges for the Hexacores narrows and centers on a reasonable number (around 4.4/4.5 GHz) then I may go for an upgrade like that. There's always a chance of getting a 'dud', overclocking wise, but with better yields, better motherboards, tuned BIOSes etc. - I could decide that I'll be happy. I had wanted to check out Skylake-K, but at this point it won't be out till sometime in 2016 (and since I like to wait around six months after release to buy a new system with most of the bugs worked out - it's just looking like it's too long to wait.

The delays with Intel CPUs and the lack of info have been frustrating (visa vi 14nm). On the plus side, I could eventually upgrade to BW-E b/4 EOL and get a new CPU and lower power usage if the performance stays the same or gets a bit better.

So, I think originally I was enticed by rumors of Skylake and a bit disappointing with HW-E hexacore overclocks, but you make some great points and I think I will actually come around. I do do somethings (mainly w/VMs) where more than four cores makes a difference.

I think the only people not getting 4.4 are stress testing with something completely inappropriate like prime95. I'm doing 4.4ghz@1.28V 24/7 encoding x265, which is almost certainly the most stressful real world app out there right now.....at only 65C with air cooling and fans at 800rpm. It's still whisper quiet. I could easily push 4.5 if I wanted to live with a little more noise and 1.35V.

For a point of comparison, I was previously using a 4790K that only needed 1.25V to push 4.5ghz, but it was burning up at 85C and fans on max 1500rpm...using the exact same cooler. That's what a much bigger heatspreader and real solder instead of that goop TIM they use on the mainstream chips will get you.

For me it's been a night and day difference - about 30-40% faster encoding vs a 4790K at the same price, without sacrificing gaming performance today, and ready for anything games throw at it in the next few years. Much less noise and much less heat. It even idles at 25C and literally every fan in my system is off aside from the CPU running at 300rpm. The board and the ram added another $150 or so, but I'm so glad I didn't wait on broadwell.

 

[mizzou]

it looks like the current roadmap favors mobile market fans, not the enthusiast market. I think I might be skipping Skylake as well....

 

[Arachnotronic]

I think I'll be skipping them as well. Skylake-E for me!

 

[Makaveli]

What time around is Skylake E suppose to be released?

 

[III-V]

What time around is Skylake E suppose to be released?

Probably 2017 at this rate...

 

[Midwayman]

I have a i7-2600k @ 4.4g. Not much that stresses it yet, but keeping up with a strobing monitor finally motivated me to overclock it. I'll probably upgrade once DDR4 becomes cheap.

 

[witeken]

Why can't they release Broadwell in Q3'15 and Skylake Q3'16?

What board and chipset are you using with the Sandy?

We're in the same "club" with this. Early in the year I discovered my own rig running at 4.6Ghz was just a smidgeon behind the i7-4770K Haswell overclocked to 4.4Ghz -- in Cinebench scores. It was neck-and-neck with the Sandy set to 4.7.

Win, lose or draw -- there's no urgency for me to build my Haswell-E until I've picked the case and watercooling parts, tested them, and waited for more BIOS revisions and maturation of DDR4 options.

On the 2600K, YMMV, but my temperatures seem low under IBT or LinX with an NH-D14 cooler. I suspect there is another 5 to 10C of "thermal headroom" after 4.7Ghz. For voltage, I'm more of a sissy about it than some: the monitored load voltage doesn't exceed 1.37V at 4.7.

Unless you lost the chip lottery, you can actually go higher with that one, with a decent motherboard and cooling, anyway.

That's interesting. I'm kind of toying with the idea of the haswell-e, because with DDR4 and everything it seems like it'd be a platform that would last quite well, making it a good match for the recent pace of CPU development (skylake might throw a wrench in that idea, but used datacenter processors would hopefully make a good upgrade path). That TDP number on the chip has been seeming like a non-starter, though, since my computer is in a pretty small room, which has been making me even look at the S parts. How is the wattage draw and heat in room comparing in practice?

Didn't Broadwell-E get delayed until 2016?

 

[witeken]

Yes.

Swiftech now introduced the H240-X which is 2x140mm for only $10 more than their H220-X. Now I'll need a new case for my next upgrade too as my case can't fit such a rad. Just happens that NZXT will soon have the matte black H440 that fits a 2x140mm rad at the top! It's like they are reading my mind or something.

Now I just have to hold out to Skylake-E 6-core.

The H440 is a nice case, however it has a TON of flaws as i listed in my review.
The H630 series is a better case overall IMO, as u can load it up with a TOP and Front radiator.

The H440 your limited to only 1 config, as i have shown here:

Another big flaw in that case is the fact its made of steel.
It will RUST with h2o setups.

Anyhow without derailing the thread even more... i'll stop here..

It's no big deal, the most I've seen the chip itself draw is 150W or so.

I've run watercooling in several steel cases and they've never rusted. As long as the steel is painted and you are not spilling the liquid constantly it shouldn't rust.

.

Just because one test shows almost no IPC improvement over SB it doesn't mean it is so in all benchmarks, on average IB provided 7% boosts over SB and HW 10% over IB so HW over SB is 10*1.07*1.1=17.7% I had an SB earlier and that's about right.

What chip?
My OCed HW draws
130 idle
270W OCCT
460W LINX !!!

Are you talking about the chip or the whole system? Because 130W idle is insane...

 

[Lepton87]

Whole system.
Insane? Look at my rig, 2 graphics cards, 8 hard drives, lots of fans, 1.2KW PSU that is inefficient at low loads etc.

I still remember the days when we saw 30-50% jumps every year. These single digit bumps are barely noticeable in practice. Since everything has slowed down the only time I really noticed a tangible difference is going from single to dual core, dual to quad, and now quad to hex. I don't think were going to see octocores filter down to the lower high end for a loooong time.

I agree that it doesn't make sense to upgrade every cycle. I upgraded from a mainstream SB to a HEDT Haswell which is quite a boost, but If I had a HEDT SB I wouldn't bother just yet.
