Haswell Refresh to launch in May, Broadwell in Q3 - how does that make sense?

[chucky2]

Both chipsets support both. Its only a motherboard implementation.

You can already buy Xeons with 4Ghz and above turbo.

How sure are you of the bolded? Are there any Z87 boards out that have announced support for Broadwell?

Does it really matter, since intel @14nm is only going to be about 10% faster than intel @22nm? (Sans the gpu, which is useless anyway.)

Meanwhile, intel's mobile competition, qualcomm, apple, etc, are each looking to increase their per core performance by 50% or more in 2014. Now that is progress. Intel can choke on their big fat margins.

10% faster in the same power envelope?

Intel is racing to scale their big cores down for mobile, while the ARM competitors are ramping up speeds but are increasing power usage.

That isn't very surprising since it's just a die shrink.

I wonder what is the battery life on a 3GHz ARM chip is like though. Would be impressive if the power draw remains the same or lower as the current top-of-the-line chip.

With that said, Intel's die shrink should either improve battery life or allow them to clock the Cherry Trail Atoms higher than their Bay Trail predecessors.

power consumption generally increases in proportion to operating frequency.

 

[know of fence]

Is there even going to be a Broadwell version for the desktop? Has the rumor that it won't make it been rebutted? If not well, then the release dates make perfect sense.

I am aware of that relationship; I think it is related to Joule's law. The die shrink has the opposite effect however, and which effect is greater is the big question. I tend to think the clock increase will have the bigger effect, but maybe TSMC will hit a grand slam.

Broadwell-K is on the roadmap. Rumors of Iris Pro graphics being included on it. Maybe it is on both, maybe just the i7. Only Intel knows right now.

I think the i5 will have it, if only to justify the extra $50-70 I am expecting Intel to want for it given it's not any faster than Haswell Refresh.

 

[IntelUser2000]

It might only be two dies - DC + GT3 for the Ultrabooks, and QC + GT3e for the high end laptops, Broadwell-K and Xeons (which the latter 2 will be 50-70 more than the Haswell Refresh GT2 version). Could be a DC + GT2 for Ultrabooks as well, but only the less than 10W models.

Haswell has 8 seperate dies(of course not including server). It's likely Broadwell has at least that much.

We already know there's:
-Dual + GT2
-Dual + GT3
-Quad + GT2
-Quad + GT3

 

[jpiniero]

It really makes sense (2 dies only) if you think about it. Those two represent the high margin parts Intel craves while letting "new" Haswell Refresh fill in the rest of the lineup. They probably aren't comfortable putting <$275 Core on 14 nm yet given how expensive the wafers must be and how lousy the yield has been.

 

[tolis626]

So with all that said,does it make any sense to build a Haswell high-ish end rig now?I mean,if rumors are true,I can't be excited about Z97.Sata Express is cool,but I'm quite sure the SSDs that support it and take advantage of it will be prohibitively expensive initially.I suppose I'll be okay with a 4770k and a Asus Maximus VI Formula,but it's too expensive of a setup to just want to throw it away for something newer in a few months time.

I could have sworn that SATA Express was dead. It doesn't matter anyway -- this year is the year of the affordable PCI-E SSD.

 

[hhhd1]

isnt't Haswell refresh = broadwell ?

just like ivy bridge is sandy bridge with smaller nm

 

[ShintaiDK]

No. haswell refresh is haswell.

Can you share more details? I haven't been watching component markets as much recently, curious about this. Thanks!

 

[ShintaiDK]

SATA Express is removed from the 9 series chipsets. And thank god for that. Worst connector in history perhaps.

Long live being stuck at SATA-3 for another 2 years then!

The cheaper, smaller transistors more than offset the increased wafer cost.

 

[Lepton87]

Everybody forgets that there already was an 4.4GHz stock Xeon Westmere CPU. Dual core and OEM only, very rare.

Just use PCIe SSDs. Its the same thing. Just without this:

 

[Abwx]

power consumption generally increases in proportion to operating frequency.

Only if supply voltage is kept constant otherwise power will increase as the product of the frequency delta by the square of the supply voltage delta , increasing frequency by 30% and voltage by 20% will result to power being
increased by 1.3 x 1.2 x 1.2 = 1.872 ratio , that is 87.2%.

Only valid if you kept temperature constant, otherwise static leakage increases so does the power consumption.

There is nothing wrong with that connector. It's certainly a lot better than PATA + MOLEX. PCIe SSDs aren't really an option for those of us off in ITX land.
