SourceIt wasn't until Ivy Bridge that Intel's integrated graphics processors (iGPs) really became good enough to allow desktops and laptops to make do without add-in boards, and now it seems that things are getting even better.
Intel has been developing a new iGP, called GT3 or Iris Pro. This chip will be included in the Broadwell line of central processing units.
We've now learned that the first commercially available Broadwell chips will be high-end Broadwell-K with support for LGA 1150 9-Series Z97 and H97 chipsets.
Only the Z97 will actually let them work at their best though, since Intel has decided that only the best chipsets should support unlocked multipliers (overclocking).
Anyway, that's not the main topic of discussion here. The real news, or rather new rumor, is that the Iris Pro GT3 will boost graphics performance by 80% compared to the one in current-generation Ivy Bridge processors.
It sounds amazing and unbelievable, but that's what you get when you receive an iGP with 128 MB of eDRAM memory. There will be some speed improvements to transcoding and Quick sync technologies too.
As for the actually x86 cores, there will be four of them, backed by 6 MB of L3 cache memory and Hyper-Threading support (four physical cores become eight logical ones in Windows).
On that note, there will be both Core i5 and Core i7 CPUs, the former with 4 MB cache, all of them with Turbo Boost (dynamic overclocking based on performance load).
Availability is scheduled for the winter holiday season of 2014, by which point sufficient 9-series motherboards should be out and about. That's essential because 8-series chipsets won't work for them.
So, to sum up, CPU performance might not make a very large leap this time, but the graphics side of things will progress greatly. In the end, it’s kind of necessary, what with AMD running so far ahead in that area.
Next year Intel is going to refresh existing Haswell lineup, and introduce two 9-series chipsets, Z97 and H97. Closer to the end of the year the company will also launch first desktop "Broadwell" microprocessors, codenamed Broadwell-K, for socket 1150 platform. As the name suggests, the processors will have unlocked clock multiplier. Perhaps, the most interesting feature of new products will be Iris Pro (GT3) graphics with integrated 128 MB eDRAM memory, which will allow new CPUs to boost graphics performance by more than 80%. Other GPU-related technologies, such as Quick sync and transcoding, will be also faster on Broadwell-K chips than on Haswell counterparts. Broadwell-K processors will have 4 CPU cores and support Turbo Boost technology. There will be Core i5 and i7 versions of these products. Core i7 parts will come with 6 MB L3 cache, and will have Hyper-Threading enabled. Core i5 microprocessors will have 4 MB of level 3 cache, and no Hyper-Threading. The CPUs will be compatible with 9-series chipsets, however 8-series chipsets will not validated with Broadwell-K chips. The processors should be available after Holiday Refresh 2014.
Broadwell-K is developed for gamers, and the iGPU will not used for graphics. Well not just for that.iGPU on a i7 part; i cannot think of anything more redundant that this if i try.
who buys a top-range CPU to use with no-graphics applications? omg i need that 5Ghz quadcore to surf the internet.
Some of that has been fixed in the OP but you're right they should do a better job by not making such silly mistakes in a task as simple as copy/cut + paste :sneaky:That softpedia article is simply horrible mangling of the original. Not to mention the errors.

Iris Pro in LGA as well as BGA it seems.

GPGPU. This will be a huge push for gaming because the XO and the PS4 is also designed to accelerate several data parallel workloads. It can be anything: pathfinding, physics, sorting, decompression, culling, or even some directly offloaded graphics workloads before the actual renderring (we may call it pre-render). There are many possibilities with architectural integration which is solve the latency and the copy overhead problem. This is why the developers so excited about the new consoles, but we need this functionality on PC as well.? explain?
does it have any secondary functions? i assumed that when using a dedicated, the iGPU just sleeps. (i.e waste of space )
You do realize that you've quoted the source(not me) & that it's just speculation at this point in time right?Current generation IVB? What about Haswell?
What utter nonsense.
This is isn't only about the GPU part - I expect proper successors to the Iris Pro SKUs with beefier GPUs than for the Broadwell K models. It's also about the 128MiB L4 cache. Crystalwell isn't a dedicated GPU cache, it's a general purpose Last Level Cache which works for both GPU and CPU loads. AnandTech tested L4 impact on CPU loads in the Iris Pro review, and the L4 cache sped up CineBench 11.5 MT by 9.5%. Most tested workloads improved, but x264 2nd pass also had a regression of 4.5%.iGPU on a i7 part; i cannot think of anything more redundant that this if i try.

Yes & that's why ShintaiDK pointed out the errors in softpedia's article below my OP, now I can amend the article but I've decided only to fix the minor typos & to quote the rest as it is.There is no IB-based Iris Pro and the original source (CPU-World) doesnt mention IB at all.
is that the Iris Pro GT3 will boost graphics performance by 80% compared to the one in current-generation Ivy Bridge processors.
ivy bridge?

As has been pointed out it's either GT4 or possibly a major overhaul of Gen8 graphics, kinda like VLIW4 -> GCN, that could yield such an improvement. The other small(er) possibility is that the GPU clocks have been majorly bumped up &/or Intel has added quad channel to Broadwell K+80% makes only sense over Iris Pro on Haswell. If Broadwell GT3 features 48 EUs then there must be some serious improvements made on Gen8. I wonder if the GT4 is still planned.
Show me the benchmarks. You know I am wondering if Intel is gearing up for 4k display capabilities?
If you've got some problems with the thread then you can report it to the mods or take whatever's posted here as is, if I were to edit every technical or grammatical mistake the source has committed then what would be the point of posting the original source's links ? By your logic every FUD article should also be banned on these forums !But this "article" makes no sense at all, it is as if some idiot just copied and pasted random snippets from other websites to get some traffic. At no point do the "facts" presented in the article support the conclusion. We ALL know Broadwell is supposed to be a big jump in terms of iGPU. That has been the general trend for the past few years, duh.
If you know the article is utter rubbish why spam it here.
And for someone who is eager to distance himself from the article you are also willing to editioralize it here to present it in better light? Have an interest in Softpedia? Posted here to get some hits on website? The author does not even know that Haswell is current generation not IVB, and Iris brand is already active. And we are supposed to take his/her word on future iGPU improvements.......yeah right.
Regardless of all that, how does any of this prove we will get 80% graphics boost in Broadwell-K SKUs? How did the softpedia clown calculate and come at 80%? Why not greater? Why not less than 80%?
This is engadget level nonsense.
