Haswell-e : Iris Pro Graphics

I have looked everywhere for some leaked info on next week's chip release but I can't find anything that describes what onchip gpu intel will be using on the new flagship cpu. Iris Pro Graphics is the latest and greatest and will probably be the one but I was just wondering if maybe there might be a new more powerful gpu they might be using and announce it next week when the release the full specs. Kinda as a surprise announcement.

Anyone got the skinny on the gpu on the new haswell-e?
 
What I meant to say is that Haswell-E will not have an on-chip GPU in any shape or form.

Welcome to the AnandTech forums.

That's a shame it sure speeds up encoding projects. Much faster than my nvdia graphics card.

Yeah, QuickSync is really nice. But since the LGA2011-3 processors are first and foremost server/workstation processors, Intel doesn't see the need to include on-die graphics that would almost certainly go unused.

At some point this is going to have to change as CPUs and GPUs slowly fuse - they'll need to embed a GPU for apps that are optimized for HSA-like environments - but for the moment they clearly don't see a need to include a GPU.

Well unless the cpu encoding performance is more than 30% faster than the latest 1150 chips i'll forego premium coming next week for ddr4, lga 2911-3 cpu and the motherboard. I don't mind paying a 30-35% premium but I need the performance to justify it,.
 
My decision on which chip to go with just took two more turns today $1100 for a new haswell-e OUCH and I can't even buy a 1150 cpu with iris pro graphics they are only for OEMd. Having rotten luck.

Haswell-E can also be had for around 400$ with 6 cores.

You can get a LGA1150 in Q2 2015 or so with Iris Pro as a Broadwell-K CPU if its so important.
 
That was going to be my next question in a separate thread but since you brought it up here I'll ask it now. I'm buying a new z97 motherboard this week. How can I get an iris pro enabled cpu on it now? I don't want have to buy two cpu in rapid succession.

You cant.

But why do you need Iris Pro and not just any regular IGP with quicksync?
 
Yeah you don't need Iris Pro for encoding. HD4600 is fine for this purpose. Iris Pro is better for games, but let's face facts, in terms of desktop gaming even Iris Pro is bottom feeding in terms of gaming performance. By desktop standards all APUs and iGPU grapihics are terrible. But if you want general performance and video encoding, you don't need Iris Pro, HD4600 with quicksync will fly.

Iris Pro is more or less intended for mobile platforms, AIO and SFF to displace the need for a discrete GPU altogether. If you're doing stuff like just video encoding, you're fine on a 4770/4790k. Outside of gaming HD4600 will do everything you need great.

What programs are you using to encode? In my experience NVidia (cuda based) cards are amazing at encoding.

I'm going for the $400 6-core haswell-e (core i7 5820k) + a newer gen nvidia card, whenever they drop. I shoot and edit video for a living and its time for me to do a major upgrade. Encoding is something I do a lot and I think this setup with crush it!

Adding in the 128mb of EDRAM besides the CPU on same package would be neat.

Huge L4 cache ftw 😛

Quicksync is dedicated logic. Would Iris Pro perform any different than hd 4600? I'm doubtful.

It seems to be quite faster when "better quality" is selected.

But then again, you could just as well use Haswell-E. Also no test with a Haswell without quicksync to show any differences to the 256bit caches and AVX2.

However in normal mode, basicly same same.

QuickSync leverages the EUs for part of its processing pipeline for better quality mode. It's not 1:1, but it does have an influence.

It isn't doubtful, Iris Pro is much faster there. Intel is using a hybrid method from EUs and their fixed function unit. The sampler performance for example is important for the speed of Quicksync.
