Intel Skylake / Kaby Lake

[TheF34RChannel]

Find the softspot in this lineup is hard. I want to say it's the 7900, but its hard to look at $1k CPU as decent deal. I guess the big question becomes coffee lake and how much it will encroach with it's i7, on the 7820x. That said requirement wise yeah it looks like the 7820 has the best clocks, it's twice the cores of the 7700, and as long as you are only using 1 NVME (maybe 2) and 1 GPU, it looks like a good buy (for an i9). Just be really picky on the board, don't go with a high option list version that may not work well with the 7820.

This time it will be a shared sweet spot I think, based on PCIe lanes: i7-7820X and i9-7900X. +$400 is an enormous jump upwards though for the additional lanes and only 2 more cores, however it'll be the cheapest 44 lanes option. Every board option works with the 8C SKU, so TahoeDust has nothing to worry about - unless he stuffs with lane crunching things, which he said he wouldn't so all is well in the world.

Right now I have my eyes on the Asus Strix X299-E. Seems like it has everything I would need without being too overkill. I came across a good deal on 32gb (4x8gb) of Corsair Vengence LED 3200MHz (16-18-18-36) the other day ($260), so I went ahead and scooped it up.

I'm eyeing the same board for the same reasons I'll bet they'll have an F version out shortly after, probably only without the WiFi but cheaper. Might pick that up instead because WiFi = ugh imo.

Where did you pick up that kit?? - Oh never mind, US by the looks of it.

Worse, cause clock to clock is SK-X worse than Ryzen in Cinebenchs. And Ryzen at 4 GHz 8c/16t has socre around the 1770-1800 points

It's a good thing then that I don't spent hours (or a single second for that matter) running CineBench

Why would CL even be compared though? It's only going to have 16 PCI-E lanes. People are complaining about the 7820X only having 28...

Did anyone else see how Intel removed their recommended customer prices for Core X on the ark site, or am I losing my mind? https://ark.intel.com/products/family/123588/Intel-Core-X-series-Processors I swear I saw them on a few days ago.

Well the problem with any of them is the alternatives. A 7820 with 8 cores and 28 threads is only 4 more than ryzen requiring a board 50% more expensive and a CPU 50% - 100% more expensive. Basically it's not that much better than a competing general consumer CPU. If it had more lanes it would be one thing. Memory bandwidth is a boon though. The mobo matters because of threads. No use getting the 5 NVME 10GBE 4 16x awesome board if the CPU can only use half that.

The 10 core keeps up in clocks, has full lanes, and separates itself from other consumer products. We can debate price/perf with another HEDT product (TR) but as a CPU it's fully within HEDT territory. I don't like the pricing and personally I think Intel could get away better slotting everything 10c and over down about $200 and still have the Intel premium pricing, but even then it escalates poorly above that anyways.

So in the end the 7820 wins value, but not by a lot, within the i9. But it just sucks that they took the neutering up the core cost tree like that. The $600 units were always full lanes before.

You do realize, for the same price you can get a x399 mobo, and a more sophisticated gaming CPU, right.

Seems like you are bargain shopping if u are going cas16, why Intel. Not to many people have reasons to spend more.

General performance. He was talking about mostly gaming but gaining more in some of the other tasks. The CL will be 6 cores so only two less, will clock higher, do better in games, and the extra's of x299 don't really apply as much. For me I have a hard time with the value of the 7820 and the 7900 would have been nice for something in between that pricing with full features. For him though 7820 is probably the best i9 for what he is looking for. That said CL will accomplish a lot of that at ~$330+$150 MB. Its a good compromise between the EOL 4c8t and going HEDT with the 7820. More multitasking than the 7700, more clocks for gaming than the 7820. A single NVME and 1 GPU seems to be all he needs and that works fine on 270, so should work fine on 370.

Not bargain shopping. Just saw a good deal on ram. If I do not like the performance of it...I'll move it to my HTPC or sell it. Intel because my 2700k has been running at 4.8GHz+ for the last five years rock solid. They have earned my next purchase.

 

[jpiniero]

If you're just gaming, the 2700K @ 4.8 is still not all that bad.

 

[TahoeDust]

Yep. It has held up great. I'm just ready to make a move. I have been fighting the upgrade bug for 3 generations of processors. The 2700k will be going to a buddy looking to ascend.

Cause the reality is that 99% of the people complaining and 99% of the HEDP market in reality really doesn't even need 28 CPU lanes. The combination of 16 CPU + 16+ chipset lanes provides plenty of connectivity and bandwidth for almost all use cases even in HEDP.

I just want to know, from were all those rumors of CFL-S pushing intro 2018 comes from, when this slide is from a week ago.

I just want to know, from were all those rumors of CFL-S pushing intro 2018 comes from, when this slide is from a week ago.

Because on the slide is says "K" version probably meaning we get 2 quads and 2 hexa core K cpus. Everything else will be early 2018 (non-k, E3 Xeons, mobile). Rumor has it also that Z370 is lacking any new features and that the actually new chipset will arrive in 2018, called z390 and have USB 3.1 and wifi.

The slide says 95W "K" + 65W parts. This image has been posted again and again on this thread.

Either it's terrible marketing designer or intentionally made ambiguous. What is clear, is that only Z370 will launch and hence no lower-end cheap chipsets and motherboards. And who will put a locked part into a z370 chipset?

It could also mean that Z370 Chipset will be available at launch and later on in few months Intel will launch the B350 chipset.

 

[coercitiv]

The marketing department did not design that slide for the world to see, it was put together for a Intel partner presentation: you know, that kind of talk where someone walks you through the slide and explains everything in detail, then probably answers questions on the same subject.

What is clear, is that only Z370 will launch and hence no lower-end cheap chipsets and motherboards. And who will put a locked part into a z370 chipset?

Yes, we already noticed this discrepancy a week ago when that pic made it to the forums.

It will be even stranger if locked SKUs launch in Aug and non Z boards launch in Q1 2018. If 200 series do no support CFL-S, then consumers buying into locked CFL will have to shell out for Z370 boards.

@coolaler.com an user claims 2x Xeon Platinum 8180 deliver a CB R15 MT score of 8301, as long as you cool the beasts properly (<80 °C). He also suggests an all-core Turbo of 3.2 GHz, really impressive for a 28C/56T part. In comparison, Xeon E5-2699 v4's all-core Turbo = 2.8 GHz for 22C/44T.

 

[jpiniero]

Kind of funny that sample is branded i7, Intel's been rearranging things so much. I guess the i9 models will have it fully enabled and the i7s will not.

This confirms what mikk posted two weeks ago And I'll repeat what I wrote then: the slow down in AVX-512 is less than what I was afraid of.

Wrong, try 5459 pts for a regular 2P Xeon E5-2699 v4 system. That means 2P Xeon Platinum 8180 is ~4-5% faster per clock than its predecessor in this benchmark (fits the previous HWBOT leaks), but we don't know if CB R15 is representative of the (overall) IPC gain it will provide. The most important part is, comparing the scores, performance is up by ~50% in a single generation, and that's before we even consider AVX-512. So far it looks like Intel did an incredible job with Skylake-SP.
