I can’t watch his videos, his voice is, odd...

I know what you mean, his voice is a bit odd.. The video itself seems to be a bit padded out with fluff

Anandtech also got one of the 11th gen test laptops:

I found this amusing:

This time around Intel is not giving the historic U-series a fixed TDP value, but instead giving it a range of values, stating that ‘TDP is a poor metric’ for the type of systems these chips go into. Despite this statement, in the next breath Intel goes ahead and quotes the base frequency of the UP3 processors as the peak 28 W value.

For anyone untrained in reading Intel product names, one might easily be mistaken when comparing the previous generation Ice Lake to the new Tiger Lake parts. Suddenly the typical ‘U-Series’ 15 W processor, such as the Core i7-1065G7, was at 1.3 GHz, but is now replaced by the Core i7-1185G7, with a base frequency of 3.0 GHz. The names are so similar, and there’s only a one generation gap, so wow, that’s an amazing jump in one generation! Right? Right??

[comparing ice lake at 15 W and tiger lake at 28 W @3:50ish in the video] Those clock speeds are exactly what last gen processors needed since in most situations they just couldn't compete all that well.
But now, there's a leap forward that should take performance to another level versus ice lake but given how poorly those CPUs performed that isn't much of a complement

They fell for the intel tricks, hook line and sinker! HC confirmed as pretty B-roll and not much else

Do we know anything about AMDs success so X570 - if one is coming with Zen 3?

[kingeri123]

I have heard that AMD have developed a new chipset with USB 4.0 and enhanced PCIE 4.0 support. Not sure if it's going to be AM4 or AM5 though.

Coreteks has a picture of the Big Navi die:

He estimates its 536MM2 in size.

Not sure who Coretek is but the anime avatar was on the money with Ampere.

Coreteks is reasonably well known,but he said in the video he replaced the surround with one from the RX5700XT,so his sources wouldn't get found out.

@CAT do you know if any existing ITX B/X boards are Zen3 certified or alluded to?

Confirmed:
Navi21 --- Sienna Cichlid
Compute --- GFX10 (gfx1030)
80CUs/5120 shaders/320 TMUs /96 ROPs
~20TF (FP32)

CFO Devinder Kumar has confirmed Hardware-Level RT
'will use ~ 20CUs from the 80CU pool for HWRT'

Not Confirmed:

- Exact Memory Configurations
- Peak Core Clock

The 500 series one should have Zen3 support?

I thought the 400 series will have Zen 3 support too and probably zen 3+. Some issuse with the BIOS size and AMD mentioned something about having to remove support for Zen 1 chips to make room.

I guess we'll know for sure soon. but if the B450 doesn't have zen 3 support ill be very annoyed.

[Jonj1611]

Not sure who you are with, but I have an MSI board and they have said they will support Zen 3 with the B450

AMD has left it upto OEMs apparently. My Asus B450I Strix has a 6+1 phase VRM and a 32MB BIOS,so I won't be happy if there isn't any support for Zen3!

CB report that Renoir support for 400 series motherboards won't be released until after the Zen 3 launch:

Google translate
Still up to the OEMs, so it does seem a bit arbitrary on AMD's part. Guess someone from their AGESA team has to provide the OEMs with support, but still.
For Renoir this is mostly theoretical as the desktop release for end users is only ever going to really happen once laptop quantities have been satisfied. By which time the Zen3 APUs might be out.

AMD Zen3 event starts at 5PM UK time:
