I've seen evidence that the 7740X is binned better, its stock turbo bins are higher than the 7700K.
Intel setting the clocks higher, isn't evidence that it overclocks higher.

I said it's evidence that it's binned better, which increases the odds of having a good OC sample. It's not possible to tell how many get over 5GHz by perusing published user results, since it's easy to infer that the worse a result is, the less likely it is to be bragged about.Intel setting the clocks higher, isn't evidence that it overclocks higher.
Yeah, that's another advantage over the 7700K.Memory overclock-ability is higher on X299 as well.
It is a niche chip that just came out. There isn't a lot of data to go on yet.I haven't really seen evidence that OC better than 7700K, it seems everyone and their dog could get their 7700K to 5GHz. How fast does the average 7740x run?
It's been clocked higher on HWBOT too.Intel setting the clocks higher, isn't evidence that it overclocks higher.
The increase from 4.5GHz -> 4.7GHz should give about 5% of that gain. The larger shared L3 cache (12MB vs 8MB) should give the rest.
CFL is going to be awesome
Skylake cache - putting aside HT, does having 8MB of L3 cache on the i7 help over 6MB cache on i5? Nope. Results were practically identical.
ntel HD Graphics 730? Any information on that yet? I thought that the graphics were to be the same. Their stats are the same on the link except for the GPU generation gets a small bump to 10.5 from 10.
I can't believe its just Turbo and cache.
Turbo frequency comparison:
http://www.cpu-monkey.com/en/compare_cpu-intel_core_i7_8700k-763-vs-intel_core_i7_7700k-664
7700K clocks merely 100MHz lower in Base frequency compared to maximum all-core frequency for 8700K. There has to be perf/clock improvement.
Cinebench scaling not 100%.
The gain never goes below 50%. There's an IPC improvement. The scaling is generally in the 85-90% range.
L3 cache and memory insensitive on Cinebench.

It's not exactly the same. I think if they call it the 730 generation they will call it "UHD 730":

By the way, Skylake is Gen 9. Kabylake is Gen 9.5 because of the media enhancements. It looks like Coffelake doesn't bring any new features there. That'll be for Cannon and Ice.
How to explain this? Coffelake = Cannonlake CPU core + Gen 9.5 graphics? Maybe they have a surprise in store for us.
IPC improvement comes from L3$ size growth and memory clock improvement. The core is Skylake.
20% higher revenue in a shrinking market is not happening and would turn it in to a growing market all by itself, not even Intel could do it,

Is it though? This is an improved process. I could see an ipc bump from process/design improvements.
Well, that's only one test of an 8700K sample. That said, if those results bear out, I think Intel took a bit of time to tweak CFL's circuit design, at least while doing the hexacore layout, if not in general. Looks more like a tock than a tick due to process improvement alone.

We will know actual IPC improvement when reviewers test with locked clocks and same memory speeds. In that case perf improvement due to L3 cache size increase will be the only factor. I doubt Intel improved L1 and L2 cache latency on Coffeelake.

The memory speed increase should also contribute to "IPC." KBL is officially rated for DDR4-2400; CFL is rated for DDR4-2666.

Because base speed DOES matter.Can't wait for the 8700K. Expecting big things from this CPU.
One thing I never get about modern cpus and marketing though. If the 8700k really does turbo 6 cores to 4.3, why not advertise it as a 4.3 cpu?
Because it's probably dependent on thermals. 3.7 GHz (or whatever) is guaranteed - turbo clocks are not. What if you live in AZ and don't have air conditioningCan't wait for the 8700K. Expecting big things from this CPU.

Intel likely did allot of work on Cannon Lake, and very well may have found a way to fit some of those changes into CFL.
Turbo 2.0 can run OVER the TDP limit for a brief period if designed to do so.
