Skylake is Model 94. This could be Broadwell-K GT3e because of the chipset. TDP is only 65W, possibly Broadwell GT3e doesn't clock that high. I doubt it will match the fastest Haswell Quadcore SKUs in CPU performance. Still Stepping 1, final Broadwell-K should do better than this of course.

Broadwell-K @ GDC 2015



Intel recently introduced our 5th Generation Intel® Core™ processors resulting in a wave of products built on Intel’s industry-leading 14nm process technology. In a new disclosure at GDC, Intel showed the first 5th Generation Core LGA-socketed CPU with Intel® Iris™ Pro graphics. This 65 watt unlocked desktop processor, available mid-2015, will bring new levels of performance and power efficiency to Mini PCs and desktop All-In-Ones. Since 2006 the 3D performance of Intel Graphics has increased nearly 100 fold (Intel 3DMark06 measurements) and powerful form factors from Acer, Medion and Intel’s own NUCs are becoming available with 5th Generation Intel Core processors with Intel Iris Graphics.

This all benefits game developers who will have new ways to create immersive games building on new technologies with multi-user multi-touch, virtual and augmented reality, and RealSense. Intel is also helping define and support new programming models like DirectX 12 (DX12) and Vulkan (the evolution of the OpenGL API), as well as delivering improved, world-class developer tools. via Intel.

By mid-2015 anyone will be able to buy a LGA Broadwell-based chip. Personally I don't care about iGPUs in traditional desktops - but at 65W and for a reasonable price (similar to Devil's Canyon) this could be a successful product till Skylake arrives. The time when a socketed Intel processor beats AMD's best APU in game benchmarks might not be too far. Also the huge eDRAM might help some applications.

Lower than Haswell...
Most likely, yes. The question is how much lower? If it manages to get within 93-95% of Haswell (4.3-4.5 GHz, roughly), "IPS" will stay flat, while consuming less power.

Unlocked Socketed 65W Broadwell Iris Pro Desktop CPU Demoed by Intel at GDC15



The next twelve months are set to be exciting times for the desktop space for Intel. While the current fifth generation mobile processors are coming to market, and the sixth generation being talked about in hushed tones, Intel demonstrated a PC that was listed as having a Broadwell desktop part (Broadwell-DT). The interesting culmination of factors surrounding this part is that it was listed as being socketed, unlocked and containing Iris Pro internal graphics.

The key elements here include the CPU being socketed (replaceable), unlocked (overclockable) and having Iris Pro, or Intel’s extended eDRAM segmentation usually under the Crystal Well name but with the much improved Generation 8 graphics architecture. While we have heard that an unlocked Iris Pro has been coming to desktop since March last year, very few details were given at the time, and the news today at least puts a TDP on such a part: 65W. Normally the high end SKUs from Intel are 77W to 85W, suggesting that this component may not in actual fact be an i7, or it could be an Iris Pro part but using one of the low power monikers such as ‘S’.

The news also puts on a more firm date, so rather than ‘2015’ we get ‘mid-2015’, which puts it within the May to September timeframe. There are two important events occurring between those dates - Computex in June and the Intel Developer Forum in August, suggesting that Intel may aim for one of these events to have a formal launch.

Hopefully there will be some tests soon.
At 65W don't expect Devil's Canyon clocks here. Assuming ~3.0-3.5GHz, coupled with >5% IPC improvement and the eDRAM pool it should still be a solid performer, and we're talking about an unlocked chip.

Conclusion: Intel is having problems getting 14 nm to clock high. That's why we're only seeing max 65 W TDP parts, and Intel apart from that abandoned desktop with Broadwell.

You should wonder why SKL-S is coming with a 95W TDP shortly after BDW-K.

Yeah, that's strange indeed. I wonder what the extra TDP headroom will be spent on. Higher frequency or more IGP EUs? I have a hard time seeing how an evolutionary Skylake uArch upgrade could remedy any frequency issues with Intel 14 nm.

I don't think it is strange. HTPC is something new to you? Just have a look to Haswell Iris Pro for desktop, all of them were 65W.

What's strange is that there is no 95 W Broadwell desktop SKU, but there is a Skylake one.

14 nm drops power consumption. Broadwell doesn't implement anything that really increases power consumption per Ghz and is expected to clock no higher than Haswell. Simply put there is no need for a 90W SKU.

Yes, at low frequencies and TDP. We're not sure what its properties are at higher frequencies. But given that there are no high frequency SKUs available at Intel 14 nm, one can begin to wonder...

Broadwell-K= GT3e= HTPC
Skylake-S= GT2= aimed for highest mainstream performance


So what ist strange? Just like Haswell R-SKUs Intel is going for a typically HTPC TDP of 65W.

Citation needed. Do you know anything about Broadwell and Skylake frequencies or are you just trolling?

Higher than Sandy Bridge and Haswell at iso TDP.

True up to a point for sure, but I doubt that holds true at the 4Ghz range. If it did, they would be releasing a Devil's Canyon replacement, not a 65W HTPC part which uses half its TDP on graphics.

At the rate things are going, desktop CPUs might as well all be BGA, since there is little or no opportunity to upgrade anymore.

They are releasing a Devil's Canyon replacement. It'll just be Skylake instead of Broadwell. The unlocked Broadwell Iris Pro is literally the only desktop Broadwell on the roadmap, with everything else being Skylake.

I mean, the unlocked 95-watt Skylake quad-core could be something other than a Devil's Canyon replacement, but...

He may have meant "drop-in replacement." That's what I was hoping for, anyway. I have a pretty nice Z97 board bought partially in anticipation of being able to drop a Broadwell into it at some point.

I'm talking about what we've seen so far on Intel 14 nm, and what we know is planned for Broadwell.

Also, ask yourself this question: Why would Intel skip introducing high TDP desktop SKUs in a timely manner, if they did not have problems reaching high frequencies? Desktop Haswell is long overdue for a replacement as it is.

TDP in a K part means NOTHING in desktop, a K motherboard can ajust tdp to wharever you like.
