Intel Skylake / Kaby Lake

[Arachnotronic]

On the other hand, presumably L3 Cache in Skylake XCC is also much smaller, so maybe that does make it reasonable.

That may be why Skylake has a smaller L3$ -- to make room for other stuff.

Well, I'm assuming they are increasing the L1 and L2 caches in Skylake Server so maybe the L3 is less needed at this point.

Pretty futile to compare overclocked Skylakes with that results, because once you overclock the locked models you lose half of the FPU. AVX/AVX2 performance is gone after that.

Well, I'm assuming they are increasing the L1 and L2 caches in Skylake Server so maybe the L3 is less needed at this point.

That's not the way it works, for server cache coherency Intel use a MESI(F) based protocol where the L1 and L2 are write back to the L3. So the L1 and L2 are inclusive in the L3 ( but L2 doesn't have to include L1). It could have been done to reduce latencies a little given the L3 average latency keeps growing with core count and with the way a core will "randomly" write to any L3 slice over the ring bus.
Because this uncore logic is a base building block the smaller SOC likely just inherit what the larger socs are doing if it isn't worth changing it.

Intel can size each L3 slice at 256k/byte increments, There are probably very few workloads where either 6mb a chip vs 8mb a chip L3 or 1.5mb a core vs 2mb a core in multi threaded makes a large difference and thus no point changing it on other chips if the big servers are already using 1.5.

Desktop Kaby Lake release date moved forward?

According to european retailer centralpoint.nl - Kaby Lake-S processors like the Core i7-7700K should be in stock December 12, 2016 - that would be earlier than the antecipated CES 2017 launch. Meanwhile some chinese websites mentioned December 10 as another possible date.

Hopefully "in stock" also means they'll sell it!

The Core i5 6400 OCed must be the best VFM CPU at the time. Exceptional performance, better ST and almost the same MT vs my 4.4GHz Ivy

And we care about AVX/AVX2 because we consumers use it where exactly ???

Well, my libc uses AVX2.... for memory operations.

Be careful, the 7700K Arachnotronic showed is likely overclocked.

It's definitely overclocked. I think it's at 5GHz.

 

[XMan]

4790K -> 7700K a worthwhile upgrade? My M.2 drive is currently lane limited also.

Probably not a worthwhile CPU upgrade, but if you are platform limited then why not? Resale value on 4790K is likely to hold up well enough.

Wonder if there will be anyone flipping their 6700s. Hmm.

Oh boy, Kaby Lake's about to drop! If it'll be available by then, I wonder how long it'll take for benchmarks/reviews to be released

That would be pretty sweet. Was expecting this in Jan\Feb. Make for a nice Christmas project.

Seems like you would really want a 200 series board to go with Kaby.
