I am much prefer intel to stick with quad core but offer a much better single threaded performance than going hex core on 115x sockets.

And I call my HDD my Datacenter.

Unfortunately, computer terminology does not work that way. No one else in the world of computers will understand what you mean if you decide to continue, and being that this is a place of communication about computer things, that is a barrier. Not that I can stop you from thinking that way, but as an absolute fact that is not that IPC means in the context of CPUs. IPS actually means exactly what you are trying to replace IPC with, which is Instructions Per Second, the combined value of IPC and Clock Speed, and the total strength of a core.

As for APUs... Frankly I think everyone is going to have to get over it. They won't always be used for graphics in the future, they will be used for compute as AMD is leaning toward with HSA. They'll become as natural to the CPU design as ALUs and FPUs. It's only a matter of time before they're introduced into the server market as well. AMD already has an APU Opteron.

well the diff here is instead of having Intel iGPU acting as a co-processor for compute. It get disabled when we plug a discrete GPU. So whats the point of wasting die space for iGPU when the GPU get disable if the user plug a more powerful gpu?
Without the iGPU taking up die space, thermal headroom, our chips would have been clock higher by default

This is a very poor implementation. Intel iGPU should not be disable in the event discrete gpu plug in by default.

I like the idea of using an iGPU for decoding videos with QuickSync. I do heavy use of SVP and madVR so the dGPU is used anyway. Why waste dedicated hardware?

Though Ok. I admit it. It's mainly for the laughs.

If the GPU can handle it.

the real problem is, it get disabled by default, u need custom software like lucid to enable the gpu, which is pretty dumb.

This is a very poor implementation. Intel iGPU should not be disable in the event discrete gpu plug in by default.

You're doing it wrong, simply put. I can use both my 4770k's GPU and my 7970 at the same time. Same with my 4670 and 7870. I'm not sure what to tell you here except that it does not happen by default on my Z87X-OC. Go look through BIOS for an option to disable or something.

As for it taking up die space... You have the exact same die that every laptop, every i3, every i5, and every non-extreme i7 uses. They are all one design with various parts disabled. It actively costs them more to make a different design just for you then it does to just leave it there. If you want a GPU-less design, go 2011. But that isn't going to remain GPU-less forever either.

I think Luid Virtu adds the ability to seamlessly pass video through one one output but changes which GPU it uses base on your load.

I have in bios the ability to use my iGPU as well as my dGPU

I can confirm that, I was using my i5s IGP for months to drive a small extra screen straight from VGA rather than buying a DP to DVI adapter.

You can also just run the IGP as a secondary GPU without Virtu. I was using mine to drive a small screen and for Quick Sync.

You guys are missing the point of that post that brought this up. It was about using the IGP only for compute, without any screen connected to it. The idea was to get to use the whole thing you paid for instead of just the CPU half. If you want to do that, for example use its QuickSync in Handbrake to encode video, it does not work. It only works if there's a screen on it (you can actually trick it into working by disabling monitor detection and forcing it to output to an invisible VGA screen).

Its compute features are currently also a bit bad if I'm not mistaken. I was under the impression that its OpenCL performance is miles away from what AMD's and NVIDIA's stuff can do. This means Intel has to do a lot to it to make it useful for this. I don't know if they are even trying. They have those Xeon Phi chips with a bunch of mini x86 cores to compete with NVIDIA and AMD instead, and I don't know if that will ever be also useful for graphics and be possible to put into normal CPUs instead of their current graphics (would be an awesome CPU I bet).

Seems this is getting way off topic, but you can indeed use Quicksync fine without anything physical connected and without using that fake screen trick.

I use QuickSync to record gameplay via OBS (I also had success with a few other apps) while the gaming is done on my dedicated AMD card.

It works perfectly, very impressive.

Then I'm sorry for writing something wrong. I guess it was just that Handbrake beta version that I tried or I was just being stupid and not configuring things right.
