...but! Will it do Meltdown?

zuypaweu• 9 years ago

probably

buryat• 9 years ago

yes, but because of the performance drop, people would have to buy more expensive cpus that run at higher frequencies.

"Checkmate" -Intel.

jjawssd• 9 years ago

Yes, and mega-tasking. Slide 3

Please don't post unsubstantive comments here.

Only 8x PCI-E 3.0? That's a little on the low side for a regular card, not to mention chips on the same interposer, no?

lettergram2• 9 years ago

I think part of the point is you wont need a GPU (at least that's the idea).

monocasa6• 9 years ago

I'm saying that it's using 8x PCI on the package to connect these two chips together, not additional PCI lanes going out to card slots.

fleetfox2• 9 years ago

It's enough. Even top end discrete cards can't saturate 16x PCI-E 3

monocasa6• 9 years ago

I guess I'd like to see much tighter integration between the two chips so that we don't have to write code that avoids the PCI bus at all costs. Today you fit your entire working set into VRAM and don't touch it from the CPU, so it's sort of hard to say "it's not a deal we don't saturate the bus anyway" when that's only because we bend over backwards to not touch the bus in the first place.

AFAICT, Coffee Lake has 24 PCI-E lanes, 8 of which are used to connect to the chipset. If they used all remaining 16 for the GPU, then NVMe and thunderbolt connections would have to go through the south bridge, affecting latency and throughput.

monocasa6• 9 years ago

I guess I would have preferred to see it be a client on QPI and be cache coherent with the rest of the system, rather than using PCI at all, but yeah, that's asking a bit much on this super short timeframe.

Intel doesn't connect to the chipset with PCIe, it does that with DMI.

Coffee Lake only has 16 PCIE lanes on the CPU, 4 DMI Lanes (about equivalent to 4 PCIE 3.0 lanes) which connect to the PCH and 24 PCIE 3.0 lanes coming from the chipset.

I mean.. I wouldn't trust those benchmarks at all.

It does seem like good news for AMD though!

dogma11383• 9 years ago

I'm not sure how good it is for AMD since their Ryzen G series APUs which also aim for the 45-60W target come with a much weaker GPU (11 CUs and no onboard memory).

Sure they would be cheaper but it doesn't really matter that much the OEMs price the laptops too close together now for that to make a difference.

I wonder if OEMs will find it easier to design a single 100W cooling system instead of 2 45W cooling systems to fit inside an ultrabook. Hoping for a new XPS15!

42% Growth CAGR in Retail Gaming NB Sales over the last 3 years

What are NB sales?

eco• 9 years ago

Took awhile to figure it out but it's "Notebook Sales" (as opposed to DT, Desktop).

SloopJon• 9 years ago

Given the context, I'd assume that NB is short for "notebook."

deafcalculus• 9 years ago

It looks like Intel won't be selling a socketed version of this, which means this will be available only in laptops and NUCs. I've had trouble with Linux on NUCs in the past. So, I really hope this goes into a new mac mini.
