So is August 21st the so called paper launch of Coffee Lake? When are the cpu and mobo going to be actually available to buy?

No. The memory controllers in the AMD setup are per CPU, so unless AMD designs a new platform that can use those memory controllers as well (basically either six or eight channel RAM), you won't see TR chips with 24-32 cores.

In fact they can, but whiout using the memory controller, meaning they will have to use the mem controller of other cpu by fabric.

Videocard just had an article where leak of i3 specs don't have hyperthreading, i was right lol.
https://videocardz.com/71740/intel-core-i7-8700k-pictured-i3-8350-and-i3-8100-specs-leaked

Well, i was sure neither 8100 or a i3 K whould be 4/8, the 8300 may still be 4/8, but the lineup whould look weird,

I bet you there will be i5 SKUs that have 4C/8T.

By best guess is that the I5-8400 is the 4/8 cpu, but that whould mean the leaks were incorrect, and if that is true, we cant trust anything.

Intel Core i7-8550U spotted in Acer NITRO notebook

A YouTube channel called ADBIG has a video with upcoming Acer Nitro AN515-31 notebook equipped with Intel Core i7-8550U processor. The notebook has quad-core CPU with eight threads, 20 GB of DDR4 memory and GeForce GTX graphics cards.

This is the first public appearance of 8th Gen Intel Core processor.

The laptop is expected to cost around 25,000 baht (752 USD).

So the Core i7-U is where the 4-core, Hyper-threaded processors went. Though a gaming laptop (NVIDIA GeForce GTX) with a very power limited U processor?

You would be surprised how well a U processor like that one will be able to power something between GTX 1050 -> GTX 1060, especially if the OEM was smart enough to have it work at cTDP up (25W or whatever is the new norm on this gen).

These units tend to strike a delicate balance between performance and heat/noise, so even if one were to use a faster CPU with higher TDP, they may just end up being thermally limited anyway.

About the processor choice in gaming laptops:

Currently:
  • Entry-level: i5-7300HQ (4 cores, no Hyper-threading, 3.1 GHz, 45 W)
  • Everything else: i7-7700HQ (4 cores, Hyper-threading, 3.4 GHz, 45 W)
Possibilities in Coffee Lake (~ to indicate my prediction):
  • i3-8100H: 4 cores, no Hyper-threading, ~3.0 GHz, 45 W
  • i3-8150U: ?
  • i5-8250U: 4 cores, no Hyper-threading, 1.6-3.4 GHz, 15-25 W
  • i5-8400H: 6 cores, no Hyper-threading, ~2.5 GHz, 45 W
  • i7-8550U: 4 cores, Hyper-threading, 1.8-[some max] GHz, 15-25 W
  • i7-8700H: 6 cores, Hyper-threading, ~2.8 GHz, 45 W
Segment of 4 cores and Hyper-threading awkwardly handled by 'gimped' U processor?
Unlike today, would i3-H become relevant? Would it reduce cost of entry-level gaming laptops (say Intel Core i3-8100H and NVIDIA GeForce GTX 1050 or Volta 2050)? Would laptops pass it in favor of i5-H (gaming) or i5-U (mainstream, ultra-portable)?
Would gaming laptops with U processors rise in popularity?

I ask because i3 with 4 cores, no Hyper-threading keeps the relative position of i3, i5, and i7 and makes sense within the LGA lineup. But i7-U with 4 cores and Hyper-threading muddles things for mobile.

Interesting future for Intel laptops.

This is pretty surprising. Look at the difference lowering mesh voltage by .033v (still at 3200MHz) and turning down LLC one notch made in temps. All other setting are the same. As you can see, the core voltage is unchanged, and comparing the average and peak watts, they are almost identical ~1% lower. But look at those temps! Max and average both dropped by 7c. I really did not think the mesh voltage affected temps this much.

Before lowering LLC and Mesh...


After...

Very interesting, although you may want to repeat testing and make sure it's a consistent drop in temps. If the two measurements are distant enough and short enough time wise, other factors can affect the outcome.

Good Idea. I saw a lesser drop (4c) when comparing before and after 2hr runs of Realbench. I'll probably run some shorter (1hr) back to back runs of a few different tests tomorrow.

This will be a major discovery if it turns out to be the case. Those temps look really good for those clocks @avx stress testing.

VRM numbers are better as well.

I'm thinking that the 7940X is going to be interesting given the benches with the 7900X vs Ryzen/TR.

The 7940X has 4 more cores and similar clocks to the 7900X.
