Ivy Bridge vs Haswell vs Broadwell

[LEOMODE]

Would there be more difference in Haswell vs Broadwell against Ivy Bridge vs Haswell?

It seems Ivy Bridge vs Haswell difference was mostly battery life being 1hr longer and a little better heat management. Any other thoughts?

Definitely more than from ivy to haswell.

The graphics performance is rumored to be up to 50% higher than Haswell and it is also rumored to be more power efficient and obviously a better CPU.

So it'll be like that of a difference of going from sandy bridge to ivy bridge (dual core to quad core)

Yeah, presumably. And hopefully that will fix a lot of the lagginess and hopefully (crossing my fingers) that it will fix a lot of display issues that people are experiencing and expressing in the forums.

Sucks how iGPU still lacks retina display. Maybe retina was just not too ready yet

I think it's definitely going to be a bigger jump from H-well to B-well.

But like discussed in another thread: in the end, for multiple reasons, Broadwell wont make Haswell feel obsolete. As far as I have read till now, numbers like "30%" to "50%" keep popping up, which sounds realistic to me. What you will probably notice in real life/real usage? Another hour or 2 of battery life, noticeably stronger graphics performance, maybe a little faster overall.

Intel says Broadwell will be 30% more efficient due to 14nm but they also claimed up to 38% for 22nm tri gate when Sandy to Ivy happend and the chips were barely any faster at all. Performance difference was 10% with the clock speed increase. Ivy offered more on the low power chips but still Intel claimed that it would be like getting two node shrinks in one. Like from 22 to 10 nm and in the end it was underwhelming.

Also initially 14nm chips won't be as good as they could be so the first batch will in performance be probably rather close to Haswell. GPU is a different question as there is a new architecture gen8 comming and more edram expected. I think for 13" the Iris gpu boost will be big.
For the 15" there might be Quad Core SoC comming which could yield much better battery life by bringing platform power down to the levels of the 13" MBP and Air. A big jump in max battery life but a smaller in average.

It will mostly just be the architectural changes that will make the biggest difference.
13" Air/Pro current is a dual SoC with a seriously bottlenecked GPU.
Gen8 GPU + edram will bring huge gains.
15" new 20nm dGPU Nvidia/AMD is possible that might be huge.
dual chip design might be exchanged for a Quad SoC (like the 13" already have) with much lower idle power. iGPU gains won't be as big as there is already eDRAM and room for more EUs or higher clocks is limited.
I expect 14nm itself to be great for Atoms but on the notebooks side to be as underwhelming as 22nm was relative to Intel's hype prior to release.

On the CPU side of things: Haswell is a new generation of CPU and is up to two times faster then Ivy Bridge for number-crunching, if the software can take advantage of AVX2. However, right now compilers are not mature enough nor there is much software with built-in AVX2 support. We will see Haswell CPUs becoming 'better' as the compiler support improves. Broadwell will have some additional performance and power optimisations.

Now, if you are talking about GPUs - Broadwell GPUs should be quite a jump from the current Haswell Iris graphics. It is also likely that we will see much broader adoption of the eDRAM in the CPU models as Intel optimises the production and improves their yields. If they manage to include a large eDRAM portion on a ULV CPU like in a MacBook Air, this will be huge.

Skylake is where we're going to see BIG CHANGES.

Broadwell is a minor change from Haswell, yes you'll maybe get an extra hour of battery life and 20 30% better graphics but the Haswell refresh was actually quite good. We saw .11ac wifi and PCIe Flash storage as well as TB2 - All these make the refresh a worthwhile upgrade.

Skylake - DDR4!, PCIe 3.0, edram as standard and even quad core configurations as the default not to mention a new architecture which will bring about major speed increases as well as further battery life improvements.

I wouldn't want for Broadwell, look at my previous threads, I was considering doing the same, however, the fact that it is delayed (meaning it will have a short life span until Skylake is released) warrants the fact that you may as well get haswell for now. By the time broadwell is released, due to the delay, skylake won't be that far off, depending on no delays of course.

Just to give you another idea of the jump between Haswell and Broadwell from ExtremeTech:

With generation eight — Broadwell’s GPU — we are expecting a 40% performance boost over Haswell. This should mean that, where Haswell allowed us to play mid-range games at 1366×768, Broadwell might finally open up 1920×1080 gaming on an integrated GPU.

WTF awesome

Skylake will also pave the way for wire-free computing on PCs, Skaugen said. The company will provide a reference platform that is based on the chip and could reduce cable clutter in PCs and tablets. The goal is to enable wireless charging and data streaming between PCs and peripherals.

The reference design calls for putting a laptop on a dock to enable wireless charging. Intel is making a dock based on WiGig wireless technology—which is three times faster than Wi-Fi 802.11ac—so PCs can stream data wirelessly to monitors and exchange data with external storage devices. The new technologies could reduce the need for ports like DisplayPort, HDMI and USB 3.0 in PCs.

Haswell to Broadwell is a Tick (die shrink), which will bring bigger performance gains than Ivy Bridge to Haswell which was only a Tock (new microarchitecture). The geeks delight in the Tocks, which bring new features, but the real performance advancements come with the Ticks.

Skylake/TB3 - & the nMP(7,8) release schedule.

Skylake is where we're going to see BIG CHANGES.

Agreed.
Had been hoping for a nMP(7) release in 2015/Q1. With more powerful AMD/Hawaii GPUs & other improvements. (As per the MacRumors buyer's guide). Then nMP(8)/Skylake in 2016/Q2(ish).

However, Intel now claim that Skylake-S will arrive in 2015/Q3. So I guess Apple could chose to delay again, and wait for the Thunderbolt-3 (Alpine Ridge) controllers etc. (Which may enable up to 3x5k or 6xC4K monitors from one nMP). Thou that would imply another huge gap between Mac Pro updates

Whenever the nMP/Skylake/T3 does arrive, we can expect to see an updated Apple Display too. Probably 5k/27" and based on the latest iMac design. Nice!
