Intel 8-core Haswell-E Slated For 3Q 2014

So, actually majority is using multi-thread performance.

Having a CPU with multiple cores and/or threads does not magically make software finely threaded in a meaningful manner. There are tons of software and games out there that show 30+ threads in Task Manager but rarely get much beyond 25% CPU usage on a quad-core or quad-thread CPU because practically all of the software's performance-critical code runs in a single thread.

After many years of being behind, I bought a haswell quad this morning and now you say there is an 8?
I throw in the towel..

The 8-cores model is not Haswell; it is Haswell-E. The 8-cores model will likely cost $1000, which is 3-5X whatever you paid for your current quad. Nowhere near the same price range.

why not designer come up with software that will perform & run in multi thread since the CPU have those capability?

Because there are several fundamental algorithms that simply cannot be broken down into threaded versions of themselves in a practical way and many more where the extra inter-process communications would introduce so much overhead that it would ruin most benefits from bothering with trying to add threads in the first place.

Another problem is that multi-threaded code can go wrong in many more ways that are often much more difficult to reproduce and debug since it opens up the possibility of having timing-dependent bugs involving multiple threads putting each other into unexpected states.

In other words, most programmers do not want to deal with the extra complexity and headaches of writing multi-threaded code unless they absolutely have to.

If its not user-friendly for software designers, so what's the use of having a multi-thread in a CPU? probably it will become useless since GPU is doing the work.

Multi-threading a CPU gives 30-40% as much extra potential performance as adding a whole core but only costs 5% more die area, which is perfect for software where extra threads use only ~50% as much CPU time as the main thread.

And even though individual games and applications may be poorly threaded, there is also the possibility of people running more than one of these at a time so having more threads and cores still increases the number of applications people can run before CPU performance becomes a limiting factor.

The new 8 cores with Intel, are they using only multi threading performance or they'll be switching to single thread?

All high-end Intel chips have HT so you can safely bet your shorts that Haswell-E 8-cores is going to run 16 hardware threads.

For lower-end chips, it varies wildly depending on whether it is a desktop or mobile chip, power range, price range and probably other factors.

I'm sure Intel will continue to claim using multi thread on their high end CPU but who really benefit from it. Now they saw the benefit of using single thread in a multi core CPU. What I believe will continue & advance in the future is multi core CPU combined with multi thread GPU. Right now even tablets, smartphones, laptop, ipad, iphone is in the process of adapting 8-core CPU.

Wow. A LOT of these comment are terrible self centered. These aren't being made and targeted at you normal lot. What do you guys want for christ sake? something made just for YOU every time something new IS unveiled. Sit back, take a chill pill and just know Intel is getting to you normal folk. This bit of news is meant for the hardcore enthusiasts and power users.

Does it come with a free liquid nitrogen mining permit to cool it?
