[Rumor] Skylake can virtualise the entire CPU to act as a single thread, 'inverse Hyper Threading’!? 2.4 times faster..

[TwistedDictator]

The comments on here are mostly just people that read the title.

 

Currently Intel wont be implementing VISC. The main reason is they dont even have license to do so. I could explain what this could be, but I cant be bothered to the majority of users that dont bother reading anything but just the title.

 

People are like "skyrim just ordered skylake" as if its going to get a increase in performance, no it wont. This isnt a increase in IPC, or would see it in other benchmarks too.

 

I would prefer to see some decent comments on here.

Java.

Which is slowly dying...

Wow this sounds pretty awesome! Funny how this is a new potential feature when DX12 is coming out which is designed to leverage more cpu cores.

[Misanthrope]

this somewhat came at a bad time with directx 12 able to use more than 2 cpu threads

 

Not really: it will be a while before proper multi threaded games come even with DX12 advantages. Also you can still gain significant improvements on literally thousands of existing games without a single line of recoding which is always nice

 

Too nice in fact, I don't think this will have such dramatic results.

Hopefully we can see some benchmarks too see if there actually is any real world benefit.

Even if this isn't real, the amount of positive feedback the idea of inverse hyper-threading is receiving makes me wonder why this hasn't been done before. Imagine if cores could dynamically adjust their 'size' depending on how resource intensive a particular task is rather than being limited to a single core and letting all of the others idle. This could open the door for a new era in physics heavy gaming. I can't help but think this would be IDEAL for Space Engineers, one of my favorite single-threaded CPU bound games.

Java.

You can use many threads in Java

Harsh words.

 

What would it be other than VISC then? I have a lot of questions regarding what these (admittedly unverified) results are showing. The issue I'm seeing right now is that if whatever IS Skylake is running actually could do a form of "inverse SMT" then that implies a lot, including idea that heavily parralellized physical architectures like GPU's would now be able to act upon single threads. Although ultimately I'm having trouble attributing this to instruction sets at all--there would be no reason for Intel to withhold information like that before release and all released documentation is showing nothing that would implment it, though I admit I haven't had a look at Intel's updated x86 datasheets. But on the other hand I can't seem to see it being anything other than implemented at the metal.

[CommandMan7]

I highly doubt this because that's the opposite of what Intel seeks to do. If AMD or Qualcomm came out with this tech, then I would believe it because they both have very weak IPC. 

 

But it would also further solidify Intel's lead... Zen could be amazing but even then would be multiple times slower than an reverse hyperthreaded CPU core. Then Intel could take a break for a few years while transitioning to a different material than silicon.

You sir have mad a beautiful post

 

OT: This is pretty cool if it turns out to be true, but I'm not entirely sure how much of an impact this is going to back with newer software moving forward. Definitely some older software and games will see a decent boost.

[kanjo]

last few years- we need more cores damn it! 

this thread - we need to take the cores we have and make them less damn it !

me - GOD DAMN IT PEOPLE I CAN'T UP WITH THIS !
first you want more cores, then you want to take the cores you have and turn them into less cores!
what the fuck do i do with all these cored apples!? 

[.spider.]

Its useless because there is no OS or program for the desktop/workstation environment that uses 1 thread.

Any program you have needs more threads for audio/graphics etc, if you run all on a single thread it will get much slower than 2.4x the gain in skylake.

But a lot programs are using one main worker thread.

Just waiting for my 6700k to be delivered, along with my maximus VIII motherboard. Totally able to endure the wait...

Finally a decent comment.

 

So if we take a better look at the benchmarks, and even other sources of benchmarks, we see a barely a increase or even performance loss when comparing to broadwell, this can easily been see in broadwell. So what can this be really? From what I personally see is that intel pretty much hardcoded on the system to run 1 thread on two cores, which will show some improvements into benches but inst matched in actual application or even multi-core benchmarks.

[Tomsen]

Arent intel supposed to go in depth with their architectural changes from broadwell this tuesday?

Then we can see, what is under the hood.

Tuesday as in tomorrow? Is there going to be a livestream or will I need to read multiple walls of text fragmented across half a dozen news sites to get the full picture?

but Google killed Java. /s

Tuesday 18 August at IDF.

I believe they'll be a livestream.

Some sites surely will do a bigger readup, a more detailed analysis.

[kacper]

BTW why didn't LTT review Skylake yet?

[Ardaen]

What you guys seem to forget in your hype is that skylake has already been tested... and there are no benefits to it compared to a 4790k in modern games, even CPU intensive ones. 

 

And the single threaded performance is up from haswell, but surely not by 2.4x and much more in line with the normal 10% generational IPC gains.

Source:http://anandtech.com/show/9483/intel-skylake-review-6700k-6600k-ddr4-ddr3-ipc-6th-generation

 

So imho there are 2 possibilities:

 

1)Either this inverse hyperthreading is a thing that has to be specifically implemented in software and therefore works only in specific situations, so forget about your DX9 games getting any benefits

 

2) This whole thing is not true

There's a needed software layer, a global front end. Jeez people do your research before you comment...

[Andrew Sh]

Pretty awesome to see new technology coming out like this.

Only thing that concerns me is how much use will the enthusiasts get out of this, considering having 4 powerful cores is optimal right now.

 

Excluding the 6/8 core intel cpus (for price reasons)

So 8 core AMD cpus suck.
4Core /w HT seems to be the max performance

Intel 4core /wo HT seems to quite often perform about 1-2%  better than i7s (for a reason I can't understand)

But then when you look at it, the intel Pentium has 2 beast cores when OC'd but it chokes a pc in games that require 4 cores (which is where gaming is heading now)
So having essentiall 1 super beast of a core is going to see similar performance to this Intel Pentium G3258.

Assuming you don't buy a 6700k  for 1 core processes, I see very limited use for this.

I think this may have some professional application use but certainly won't be of any use in editing / gaming.

Nonetheless, a pretty cool new technology

[Agosto]

Probably a wonderful thing for Kerbal Space Program players

[Ardaen]

Ok Mr. Computer Science Major. At least enlighten us and explain to us how it would work, or do you only stop by, complain about "missing resarch" and then move along?

What would this software layer be? A background running program? Does it have to be application specific? Would it help with gaming? Which applications would it help with?

 

You know, not everybody can be as godly smart as you, solving the problems of humanity in your thesis.

[That Norwegian Guy]

Excluding the 6/8 core intel cpus (for price reasons)

 

And why would that be?

A 5820K + "low" end (which is high-end compared to consumer) X99 board costs about the same as a 4c/8t consumer chip with high-end motherboard anyway.

 

Also, Star Citizen devs promised 6 cores utilized.
