Haswell-e vs broadwell - performance & necessity?

[lieutenantfrost]

I know this question has been asked here before and I've checked out those posts. I've been waiting to upgrade my gaming rig and I was expecting haswell-e to be available in july as they said it would be for the start of Q3, however I read this morning that it won't be available till September. and Intel CEO confirmed that Broadwell won't be available till late oct early nov. Broadwell is supposed to offer a 40% boost in performance, and since a broadwell-e chip is likely at least a year away. Waiting 1-2 months for that kinda gain doesn't seem like a long time.

My Question is; Based on past performance of "e" chips, if both processors were available today which would be the better buy? I know this is impossible to answer accurately Im really just looking for opinions.

clearly each generation of technology brings improvements in performance. So successor generations (all other things being equal) are more desirable. The issues with Ivy Bridge overclocking is an exception to that rule, although IVB performance still exceeded Sandy Bridge.

I doubt that Broadwell will outperform Haswell by 40% Since Intel has no competition, why would they push such a massive upgrade in performance? Or if they did, it would be accompanied by a similarly massive increase in price.


The current e- generation is getting fairly long in the tooth. I had go bite on my teeth and build an interim low-end SB-E machine last year, and wait for this year's upgrade. It was always scheduled for around September - there're no surprises there.

THe big news earlier this year was that Broadwell slipped, but that got us Devil's Canyon as a stop-gap.

They are talking about the built in GPU. The GPU will be 40% faster.

If you want to overclock, just go with a 4790k. Otherwise a 1231v3, with a less expensive board, for more money towards GPU.

Yeah, the 40% is the integrated GPU gain. The CPU is only supposed to have a 5% or so gain. That being said, I am looking to build a Haswell- E around November. I know the Broadwell will be coming out, but I think the DDR4 will be worth it. As I see pre-orders on Newegg right now for 32 gigs of Crucial 2400mhz DDR4 at only $460. The DDR4 isn't as expensive as I thought it would be at release. Correct me if I'm wrong but I don't think Broadwell will support DDR4 right off since it's using the Z97 mobo. I would personally say that Haswell- E should be a decent build that should last a while. I'm coming from a Sandy Bridge i5 2500k myself. It's still running strong, but I figure a Haswell- E will be a nice upgrade.

Haswell-E for going beyond 4 cores, DDR4, Quad Channel ram, more PCIe lanes. Dual QPI some Xeons for 2 socket CPU support
Broadwell still stuck at quad core, DDR3, Dual channel ram

This platform is interesting for another reason. As the Haswell-EP Xeon range (from which Haswell-E desktop variant is derived) has three main die flavours — 10-core, 14-core and 18-core, the latter one way too similar to the Haswell-EX of course — you may have some Haswell-E desktop boards able to accept some of these humongous Haswell-EP chips. Imagine the 18-core monster with 45 MB L3 cache, many game codes would (almost) never have to leave the cache itself.

Add to this the rumoured confirmation that, unlike their predecessors, Haswell-EP Xeons, including likely thae 14-core and 18-core flavours, will have several top bin un-locked and even liquid-cooling optimised variants meant for HPC, workstations and high frequency trading, and you can guess the implications: the Haswell-E and Haswell-EP platforms will again be the overclocker’s heaven.
