The XPS 13 does look fantastic, but I'm going to hold off until Skylake. Broadwell simply isn't worth it with Skylake just around the corner.
Well unfortunately a "poor launch" would seem to indicate to me a product that is not quite living up to expectations. It is already late, and I dont know how long we can keep making excuses for the performance based on the platform. The chip is part of the platform, and its performance has to be evaluated in that context.
That said, I think too much criticism is being made about the performance of the low TDP parts, but I was hoping for more from the 15 watt ones. I mean that was supposed to be the point of Broadwell, much better performance per watt allowing all these super thin and light devices without sacrificing performance and giving better battery life.
That Dell XPS 13 sure looks sweet though, and the performance is probably "good enough" if the battery life is outstanding as it is claimed to be.
From the testing I did on an i7-5500U the temperatures seem fine it's the power limiting that held it back. Then again HSW 15W chips had a similar experience. The BDW-U idle power is impressive though and maybe it's here that the big savings are made in power efficiency rather than at full tilt.To me it looks like Broadwell-U HD5500 suffers from low clock speeds, means most of the IPC improvements are lost. It's either a energy consumption or temperature issue, or a combination of both.
What sort of performance increase did you expect? Any particular benchmarks in mind?I think too much criticism is being made about the performance of the low TDP parts, but I was hoping for more from the 15 watt ones.
So as I understand, the Broadwell U HD6100 is still slower than the HD4600 graphics processors in desktop Haswells? So even Broadwell U is too slow to run esports games like Dota 2 at 1080p until we get faster Broadwells.

Do you have seen HD6100 benchmarks?
I've seen it somewhere (can't find where) that intel expects a +20% gain with GT3-U over GT2-U.
You should give a source then. HD6100 is coming for 28W SKUs. Quite a difference to 15W GT2 Broadwell-U.

Intel will denote this silicon with HD Graphics 6000 branding on 15W processors and Iris Graphics 6100 branding on 28W parts. Compared to the "baseline" HD Graphics 5500 offered in the smaller die, Intel says users can expect an increase in performance of up to 20% with the HD Graphics 6000 and up to 50% with the Iris Graphics 6100—and all without the use of on-package eDRAM. Only processors with Iris Pro graphics will have eDRAM, and Intel hasn't announced those yet.

I'm not aware of any information besides these foils, which compare against prior gen:
"Up to"
Notice the use of the word "better" instead of "faster" in that slide. Marketing guys are still at it.
Better is such a vague word. It could be faster, it could be IQ, it could more or less be anything.
Benchmark numbers is what we want

So you were wrong, 50% for HD6100 according to this. This makes more sense.
I just started reading AnandTech's coverage and I see that, surprisingly, it isn't Anand, CPU editor, who wrote the 2 articles but Ryan smith, GPU editor. It seems Anand is busy reviewing smartwatches.
hahahahah... Iwatches
