Guessing that also means we won't see any original Lakefield designs actually make it to market?

Lakefield comes later than expected, no devices this year. As I said some time ago, the situation with Gen11 powered devices seems similar to Gen8 some years ago, only a few and very limited, the real deal is coming with Gen12.

Not much relevance to this thread but I seen zero point in posting a new one. This one has basically turned into Intel 10nm everything.

Heres the first picture that i've seen of an Agilex FPGA. Package significantly smaller than S10.

Err, Broadwell on mobile had a full release. They did refresh U and H with Skylake 6 months later instead of the typical year but it was widly available.

And certainly Intel has an incentive to move onto Tigerlake if it's using chiplets or something that makes it easier to yield.

When it came out Broadwell was almost dead.

Broadwell Q1 2015
Skylake Q3 2015

The lifetime for Broadwell was short, it was quickly replaced by products with Gen9 graphics over the entire lineup and the driver support for Gen8 closed down really fast. Also Intel didn't even launch desktop CPUs with Gen8 beside the Iris Plus models.

Yeah that's what I was saying, 6 months instead of a year. But it was widely available, unlike Icelake. There was pretty likely a lot of Broadwell and Skylake on the market at the same time, esp if the OEM was going to move from DDR3 to DDR4.

No complaints from me. Interesting that Intel has been able to produce this FPGA on 10nm while they're struggled with so much else . . .

It was no contest to Gen9, Gen8 was extremely limited in comparison with a short lifetime.

Gen8: partially released lineup (basically mobile only)
Gen9: full release lineup, more than one generation
Gen11: partially released lineup (mobile only)
Gen12: full release lineup, more than one generation

I'm not only talking about the availability, I'm also talking about the lifetime and support. As I said the driver support for Gen8 was very short and lousy as a result of the low impact because of the limited lifetime. I'm expecting something similar for Gen11, actually it could be a repeat. Gen12 on the other side should stay for more than one generation, Alder Lake for example still comes with Gen12LP graphics.

Lakefield was initially planned for this year, I think we can forget it. It's delayed forever, I doubt we will see it widely available, maybe they should focus on Lakefield-R.

It's only a very limited release so far plus FPGAs are great on bad yielding processes since you can get very granular with the block disabling caused by defects.

Intel Tiger Lake Support Lands In Their NEO OpenCL/Compute Stack

  • There have been PCIe IDs added for 2/5/12/15/45/65w versions, all using GT2 Gen12 graphics.
  • L3 Cache size increase to 3072KB/core compared to the 1920KB/Core on Icelake, as previously leaked. L3 Bank count also doubled
  • VS/HS/DS/GS thread counts are reported at 336, up from 224 threads with Icelake/Gen11.
  • 64KB pages is also enabled compared as part of the run-time features compared to Icelake/Gen11.

I think something similar was brought up earlier, but it's probally more just theoretical placeholders than actual products for anything other than the 12 and 15 W models. Although it would make sense if some were Rocket Lake models.

Speaking about Tigerlake, there was some Intel Developer Conference in Tokyo. Intel once again told their aim is a graphics doubling over Icelake.

but Mr. Yasuo said that Xe's performance target is `` FPS (frame per second), aiming for 60 frames in an environment where Iris was 30 frames '' Said.

Since Xe is mentioned I think they are talking about a discrete card and not Tigerlake IGP.

No they were talking about Tigerlake, it was basically an Icelake session with some Xe talk. Read the translation, he is saying Xe aims for 60 fps in these cases where Icelake currently gets 30 fps. Discrete cards would get much more than twice the Icelake iGPU gaming performance, even with a low end discrete.


TGL iGP is also Xe.
It's a branding like GeForce or Radeon or Adreno or whatever.
Yes exactly, both Gen12LP and Gen12 are Xe branded.

Does anyone know if Cascade Lake X will have hardware based security mitigation? Should this improve single threaded performance vs comet lake ?

All Cascade Lake CPUs have some additional security features enabled via hardware changes. I don't know about Comet Lake.

It should have all the same mitigations in Cascade Lake-SP and Cascade Lake-AP. To make things more confusing, I think there are multiple steppings of Cascade Lake, with the older ones having . . . fewer mitigations? I think? Anyway:


What is unknown is if Zombieload MDS will affect Cascade Lake-X. Cascade Lake-SP and -AP are vulnerable to that one.

got my hands around the xps 13 with icelake i7 ....that fan is pretty much always on..

but the general feeling comparing to the xps 13 with i7 8550U that the icelake is a generation ahead
system etc is much faster, overall when calling on MS teams much better
I tried only some excel calculations and i7-1065G7 vs i7 8550U is about 30% faster, really a speedup

but I wont buy it, seems Intel must handle the heat flow density with 10nm

Is it possible to undervolt it? I remember toying with XPS13 ~3 years ago, had to undervolt it pretty hard with XTU to keep thermals and noise reasonable. I think -0.1V offset was what I've settled in the end.
