Some may think that Intel Corp. has slowed down execution of its roadmap when it concerns mainstream microprocessors for desktops and notebooks. In fact, there are some delays with the code-named Broadwell chips and client platforms in general. But slides from a new Intel Xeon roadmap prove that the chip giant is not slowing down on the server front; quite opposite, it is accelerating.

The foreseeable future of Intel Xeon includes new processors based on Ivy Bridge-EP/EX designs, such as Xeon EP for four-socket servers or Xeon EX for multi-socket enterprise-class machines, just as expected. But a more distant – second half of 2014 – second half of 2015 – future of the world’s most used commercial processor looks somewhat more exciting from many points of view. The Xeon chips due in the next couple of years will not only get new micro-architectures along with innovative capabilities, but will also demonstrate unprecedented core-count.

Based on slides from Intel’s roadmap published by VR-Zone web-site, Intel is currently working on Xeon E5-2600 v3 “Haswell-EP” with up to 14 cores due in late 2014 as well as Xeon E5-2600 v4 “Broadwell-EP” with up to 18 cores chips due in the second half of 2015.

Both future Xeon E5 microprocessors will have a lot in common despite different micro-architecture of the cores. The new Xeons E5 for dual-socket configurations will sport quad-channel DDR4 memory controllers, 40 PCIe 3.0 lanes (enough to support a Xeon Phi as well as a high-end SSD) and two QPI 1.1 buses. The code-named Broadwell-EP will have slightly better memory controller with support for 2.4GHz DDR4 as well as 3DS LRDIMMs.

Intel’s own benchmarks imply that the future Xeon E5-series microprocessors will be 25% - 80% faster compared to existing Xeon E5 “Ivy Bridge-EP” thanks to boosts from increased core-count, enhanced micro-architecture and other innovations. It should be noted that there will be Xeon-EX enterprise-class offerings with even higher core-count and even richer capabilities (including those that will be inherited from Itanium chips).

Besides massive speed bumps, expect the forthcoming Xeon chips to include improved virtualization capabilities thanks to new features like page modification logging, posted interrupts, cache quality of service monitoring & enforcement, and memory bandwidth monitoring. In addition, Intel is projected to implement new management and security technologies.

Both Xeon E5-2600 v3 “Haswell-EP” and Xeon E5-2600 v4 “Broadwell-EP” will rely on Intel C610 chipset (code-named Wellsburg platform) and will feature generally similar capabilities when it comes to input/output interfaces.

Intel did not comment on the news-story.

Release an 8 core desktop CPU @ an affordable pricing.....I know that never happens from Intel

Apart from cost, what is stopping the enthusiast from moving to a workstation or server platform and utilising these type of Processors?
Surely you can still use a dedicated Graphics card in them?

For a workstation class CPU consumers have to pay around 1 to 3k $ for just the processor alone another 1k or more for the mobo and the list goes on. Don't think even the enthusiast people have that much money to spend on a computer.

The whole episode of low performance high price desktop CPU is due to the non-competitive AMD CPUs.I'm still stuck at my 3.5 year old overclocked Core i5 750 CPU. If I wanted to upgrade, which CPU offers at least double performance at less than 250$? None.

You're exagerrating here. A high-end dual socket WS/server mobo does $500-600, and one can easily compensate for lack of cores in a single socket system by going with a pair of highly clocked 4, 6, or 8 core CPUs on a two-way system, instead of shelling out $3000(+) for the 16 or 18 single core counterpart.

Plus you can't overclock on workstation/server CPU/mobo, so in many programs 4 cores at 5GHz is faster than 10/12 cores at 2.7Ghz.

Microservers are the growth area. Intel will keep the big core server market - but it is not growing so rapidly.

Meanwhile we are stuck with quad cores for desktops, while majority of games and apps don't use more than 2 or 3 cores on Windows environment.
What a waste...

P.S. this is also because o lack of competition, if AMD would have something on the same level since the first Core was released, probably 8 or 12 core CPUs would have been mainstream by now..

Programming for multiple cores is not easy. That is why it hasn't happened (8-12 cores on desktop) TAViX. Even having 100 cores would not have changed the development picture. However, that is why AMD HSA is such a breakthrough - because it makes programming for a multicore + HSA processor much easier. It's not just the processor that gets engineered - it's the software to program that processor too.

I've done a lot of multi-core SW development for a few employers, and IMO the difficulty of programming for multiple cores is highly over-rated. It's really not a big deal for a competent SW developer, provided that your workload has parallelism to begin with (some loads are inherently serial, but those are actually less common than many people think).

Multi-core programming is also gradually becoming easier with improved libraries/tools and HW features like Haswell's TSX. TSX provides transactional memory (TM) and hardware lock elision (HLE). TSX/HLE is actually a pretty big deal because it allows you to use a "coarse-grained" locking scheme (one lock for everything) and yet have processes automatically "share" the lock in cases where their accesses don't truly conflict (if they do conflict then they automatically get rolled back to where they should have taken the lock). It gives the developer most of the benefit of a more advanced "fine-grained" locking scheme without the effort and deadlock risk.

So in short I'd say that by the time Broadwell-EP comes along we'll have no trouble using those cores...

Rob Muñoz, a distinguished engineer at LSI:

"Parallel software is hard to develop, maintain and evolve," Muñoz said. "There's a graveyard of companies who have tried, but the industry is stuck with multicore because it’s the only way to scale chips," he said.

Has Intel Published any information on how these TSX instructions are implemented internally, or what processor workloads show the most benefit from Intel's TSX implementation? And like all Speculative multithreading some workloads perform poorly, while others perform better! the K Haswell series SKUs do not support TSX, and I'm not sure about the E series, non server SKUs! For sure Intel does not like its unlocked consumer SKUs cannibalizing sales from its low end server SKUs. The EETimes article is a few years old now, and I am sure C++ amp, AMD APP, OpenMP, has been introduced/Updated/Improved since then. With the parallel SDKs, and libraries programming for many cores is not as difficult as it once was.

There is not an O/S's in use by the consumer and average punter or enthusiast which require anything like this.
It is aimed at enterprise sector which have O/S's to use this type of CPU. Us mushrooms in the consumer end are fed the proverbial food for mushrooms. This is by both the Win-tel partners as they are leaving the enthusiast to bemoan their fate instead of switching their O/S.
