It reminds me of the launch of Socket AM2 CPUs. As a consumer, I hope we see a repeat of the market upheaval a couple of months later.

Having just built a Z170 system a few months back, I'm thrilled with the news that Kaby Lake offers nothing substantial except for 4k DRM.

And most stores seem to be charging a ~$30-$60 premium on KabyLake CPUs over the Skylake models they're replacing.
All in all, the typical of what you'd expect from a new CPU release from Intel.
Zen couldn't come fast enough.

It still has less cache than the Core i3 equivalent, right?
Yep, AFAICT. Ordered one, will see how much it affects performance.
My bet, FWIW, is that it'll be pretty close to i3-6100 clock for clock due to faster memory supported, which should offset the smaller cache to a certain degree. And of course, the i3 will run circles around it where AVX2 is used heavily, such as y-Cruncher.

yeah I was reading the arstechnica article, and have known progress has slowed in the last few years but I didnt think it was this Dire
Core i3 can have either 3mb or 4mb of cache.
… and now this happens:
Short summary:
Debugging mechanism in Intel CPUs allows seizing control via USB port
The JTAG (Joint Test Action Group) debugging interface, now accessible via USB, has the potential to enable dangerous and virtually undetectable attacks. JTAG works below the software layer for the purpose of hardware debugging of the OS kernel, hypervisors and drivers. At the same time, though, this CPU access can be abused for malicious purposes.
On older Intel CPUs, accessing JTAG required connecting a special device to a debugging port on the motherboard (ITP-XDP). JTAG was difficult to access for both troubleshooters and potential attackers.
However, starting with the Skylake processor family in 2015, Intel introduced the Direct Connect Interface (DCI) which provides access to the JTAG debugging interface via common USB 3.0 ports.
Goryachy told SC, “We have reported this case to Intel. As of today, this mechanism can be exploited only on Intel U-series processors.”

Getting 15-20% lower power consumption at the same performance level, without microarchitectural changes or a new process node is pretty impressive, IMHO.
I understand Kaby Lake looks disappointing for anyone on this forum; Most here care more about performance, CPU or GPU, more than anything else. It's the same if Bugatti announced their new Veyron had 20% better mileage instead of 20% more hp; Useful, but not sexy.
Cheers

I think its also the fact that broadwell and skylake have both been meh and then intel followed it up with super meh. 10nm better enable higher clocks then this 14nm+ rev kabylake otherwise cannon lake is going to be ultra meh.

I think Haswell was still pretty good.

I know this is the wrong thread, but I've seen users claiming some games refuse to run on Kentsfield Core 2 Quad and Phenom II CPUs due to lacking SSE4. Is SSE4 widely supported nowadays? How about AVX?
I saw Capcom patched the upcoming RE7 for Phenom support. Dishonored 2 as well received a patch for them. There was a thread on B3D here about AVX support awhile back too.
Anyway, I think the desktop has been boring, but Intel has been deep diving into power efficiency. To put Core into tablets and make them unbeatable in notebooks.

I read somewhere they have an entirely new architecture in the pipeline. I'm not sure if that's a replacement for the current setup or a sidegrade. I'd be curious what difference it would make for instance if they were to drop legacy support and go with a clean sheet desire based around only modern architectural standards.
