Intel to launch 6 core Coffee Lake-S CPUs & Z370 chipset 5 October 2017

humbug said:
Nah, most people have no independent clue about what they are buying, they just do what mainstream reviewers tell them to do, 90% of those are still saying any Intel CPU is better than any Ryzen CPU, even with Intel's current pricing, in Steam Hardware survey AMD are still losing ground to Intel.

Intel are still selling vast amounts of 4 core CPU's for £250 and £350, many times more than anything AMD are selling.

So the idea that Intel will drop its per core price by 40% is deluded, for what?

It's not unheard of though is it? Intel did it in 2007, when at that point they had no real competition from AMD with the Q6600, which was launched at over $800, then in less than 6 months it was only circa $260. Don't forget that at the time they also had high clocked dual core parts at higher frequencies at the same or greater cost also. Yes the situation is a little bit different here, as Intel have had 6 core CPU's on the market now for many years, albeit in the HEDT segment, and they now also have to be seen to be making an effort to be trying to compete with their rival, preventing market share loss.

I'll leave it at that for now, on the cost side of things, only time will tell as they say. :)
 
Didn't the Q6600 only lower in price because of the newer Q9xxx series? Can't really remember that far back since my first desktop was a 0th generation Core i7.

CFL-S (LGA1151-Rev.2?)

CFL-S Core i7: 6 core 12 threads, LLC 12MB
CFL-S Core i5: 4 cores 8 threads, LLC 8MB
CFL-S Core i3: 4 cores 4 threads, LLC 6 / 8MB
All three of the above line-up GT2 graphics are built-in.

CFL-S Pentium: 2 cores 4 threads, LLC 3 / 4MB
For models with LLC 4MB, GT2 integrated graphics are included.
For models with LLC 3MB, GT1 integrated graphics are included.

CFL-S Celeron: 2 cores 2 threads, LLC 2MB, GT1

1. CoffeeLake-S (hereafter referred to as CFL-S) is available from Celeron to Core i7.


2.
CFL-S Core i7 is powered by 6 core 12 threads, LLC 12MB. Compared to the previous year, the number of cores / threads and LLC capacities increased by 50%. The Rebalanced Smart Cache Hierarchy * applied here has not been applied compared to Skylake-X (which probably overlaps in a six-core segment, which will appear a month or two ahead of time).

(*: Skylake-X reduced the L2 cache capacity from 256KB to 1MB, instead of reducing the L3 cache capacity from 2.5MB to 1.375MB and changed the cache policy from inclusive to non-inclusive. I think it will help to improve the IPC. It is a feature that does not apply to KABI Lake-X.

3.
CFL-S Core i5 powered by 4 cores 8 threads, LLC 8MB. Compared to the previous version, hyperthreading increased 100% of threads and increased LLC capacity by 33%.

4.
CFL-S Core i3 is powered by 4 core 4 threads, LLC 6 / 8MB. Compared to the previous version, Hyper-Threading has been removed, but with 100% increase in core count, the number of threads is the same and LLC capacity has increased by 100%.

5.
All three of the above line-up GT2 graphics are built-in.

6.
CFL-S Pentium is powered by 2 cores 4 threads, LLC 3 / 4MB. Compared to the Pentium except for the G4560 and above, the number of threads increased by 100% due to hyper-threading. For models with LLC capacity of 4MB, GT2 integrated graphics are included. For models with 3MB, GT1 integrated graphics are included.

7.
CFL-S Celeron is powered by 2 cores 2 threads, LLC 2MB, GT1. There is no unique change here.

8.
The number of pins in the CFL-S is 1151, and the horizontal and vertical dimensions of the CPU package are also physically the same as those of the existing SKYLAKE / KABIREK. It is the manufacturer's consideration for the manufacture of new motherboards. (To be able to recycle parts such as socket as much as possible.) However,

9. Motherboards that support CFL-S are restricted to use with CFL-S only. It is said that the 'Refreshed Z270 chipset' will be called Z370 and the socket name will also be differentiated by LGA1151 v2 and so on. You can not use the CFL-S on a Z270 board that is not named Z370, nor can you use a Kbilek sub CPU on a Z270 board named Z370.

10.
The Z270 and CFL-S will live together until this year (called Z370). In the first quarter of next year, the official 300 series PCH Z390 will be released. Unusually, this PCH is called Canon Lake PCH, not Coffee Lake PCH. (The 200 series was called Kabira Lake PCH.) Maybe it's a double line that the chipset will support up to next year's Canon Lake, right?

11.
Therefore, during the second half of this year, the Z270 (which will be called Z370) is the only supported platform for CFL-S. Q / B / H series chipsets will be updated to 300 in the first quarter of next year.
Q370, Q360, B360, H370, H310
These include Q370, Q360, B360, H370, and H310.

12.
I do not know why Kavi Lake-X is coming out (...)

Surely the only way Coffee Lake S will do well is if existing 1151 motherboard can use them, especially if they stick to a $350 price.

Why would you get a Core i7 and new motherboard with zero upgrade paths when you can get a 7800X or get a Ryzen system.

The i5 chips look like decent Ryzen 5 competitors if they clock high like Kaby Lake and maintain the current i5 prices.

I am expecting the 6 core coffee lake cpu to clock much better then the skylake x chips as well has having better IPC by 10-15% so I'd argue the other way. Why would you buy a 7800x and a more expensive board when you can have a faster coffee lake chip on a cheaper platform? A lot of people talk about motherboard upgrade paths but who realistically upgrades their CPU that frequently that it matters? I have never upgraded a CPU without also getting a new motherboard because by the time i need to upgrade, my current board is 3-4 years old and i am upgrading to a new platform.

Sorry where is this 10-15% IPC jump coming from? Intel only improves IPC with their "architecture" stage, which was Skylake (and even that was only ~5% over Broadwell if you were lucky). Kaby Lake was "optimisation", which in the end was primarily just a clock speed boost, and Coffee Lake is another "optimisation" because their 10 nm node wasn't ready in time for desktop parts. Haswell was the last "architecture" stage that actually produced a noticeable IPC bump, like Sandy Bridge before it. Even the "process" stages haven't improved IPC much (Ivy Bridge and Broadwell).

Cannonlake is meant to be the next "process" stage but so far we don't even know if that will appear on desktop at all (similar to how Broadwell only made a cameo appearance before Skylake). There are unlikely to be noticeable IPC improvements until Icelake (currently slated for 2019).
 
There is no IPC increase, well none worth caring about 1-2%, just base clock will be higher, and boosts will be higher, so Intel will market them at faster like they did with Kaby.
 
Ah ok, so no IPC increase coffeelake. Still I'd rather have coffeelake over a 7800x given that it should clock much higher.
 
I can't believe they're changing the socket again. There's surely no technical reason for them to do that. It's insane. Based on previous history where two generations share a socket and that we've now had Skylake and Kaby Lake on 1151 I'm not too surprised, but this is different because as mentioned, this isn't even a new generation of chip, it's just another refinement.

Huh? Coffee Lake is socket 1151, unless I've missed something?

coffee lake for normal users should still be 1151, the new HEDT stuff is a new socket for more pcie and memory im guessing.

Perhaps I am jumping the gun because nothing official has been announced, but I've seen a few mentions about it being socket 1151 v2. This wouldn't surprise me, given that Intel had socket 2011 and 2011v3 for HEDT before.

Although to be fair, socket 2011 was X79 and DDR3 whereas socket 2011v3 was X99 and DDR4 so they were bigger changes.
 
Yep, I've seen the mention of v2.0 LGA1151, which states that the new CPU's would only work in Z370 etc. Series of boards, and are not backward compatible, probably due to the extra power pins needed for the 6 cores. :)
