Maybe AMD themselves don't fully know how DT Zen5 is gonna play out. Like, they need the laptop chips out the door for BtS and AI, and at lower TDP it works pretty darn nicely. But are they still messing with desktop Zen5? AMD have never been amazeballs with their marketing, but we've never been this in the dark after a major presentation before. Are they still messing with BIOS stuff and don't 100% know where it's gonna land... ?

The two months until release would indicate that yes, but frankly that's weird. It's not like they didn't have tons of AM5 boards out for years.

Frankly I don't think it's marketing incompetence, there's way too much strangeness for it to just be incompetence.

Yeah we were so busy with the weirdness for Granite Ridge that we didn't talk about it at all: Strix is promising 25-50% uplift over PHX for games, which puts it squarely where I wanted it, at 1080p medium gfx for all games. That's a huge win, and the amount of Strix laptops is immensely higher than anything we've seen before. The wins are very very real there, throughout all the solid Barcelo/Rembrandt/Phoenix years, we never had even close to that amount of laptops.

Whatever really changed with Strix, it changed hard. The game is now very open on laptops between QC and MAD both entering the race in a much stronger way. Intel looks like it's not putting much accent on MTL (understandable lel) and just intends to hold until LNL comes to smash the party in the low power/efficiency range. Whether LNL destroys the competition there or not, Strix is still highly successful in the high perf laptop segment. That's a first in possibly ever.

And Turin, even if it is merely 16% better than Genoa (I doubt that it won't be more), is already deleting the value of SRF. SRF seems to be within 95% of the perf of Genoa/Bergamo, it's a genuinely great product that smashed my expectations but it's too late. It's competitive with last gen, a sort of AMD vs Nvidia RT situation. SRF also showed how EMR is completely behind in perf/W in a ton of spaces, so...
Within 2-3 months Turin should come out and show just how pointless SRF is in the current market.
It does raise an interesting question for the future, about Z5 LP core. If SRF can take a lot of the market due to better perf/W options even after Turin is out (144 cores good cores at lower power is already going to satisfy a lot of customers), then I wonder if AMD won't be tempted to try a ridiculous 512 LP cores thing by Zen 6. Just a random thought, but SRF is an interesting experiment and might succeed despite Turin having the perf/W victory pretty soon.

Im kind of surprised we haven't seen more from the motherboard manufacturers about the impending x870 board releases.
Maybe everyone's too busy reporting on Intel adding CAMM2 and a new socket. To be honest that's way more hype for mobos than Zen 5 on the same mobos.

Reporting on is different than no official press releases. I mean they showed boards, why not a presser about them?

Question - Is camm2/lpcamm2 a different controller need or is is just different end packaging/mounting?
So it possible we may get AM5 mobos with camm2/lpcamm2 support?

One thing is clear this was an odd zen launch. Zen 3 and 4 were better presented and a lot more information was given to the press.
Maybe something happened inside AMD HQ? A COVID outbreak that was kept under wraps? Something that massively affected their productivity for quite a few days and when they returned, they were not the same before?

Since before the pres I was saying it was too much to do. And the pres was bad, by my standards. Lisa just glossed over everything without having the time to insist on the good points.
I loved that torpedo about AI area due to MS' bullcrap though.

The thing is that Bergamo has better perf/watt, and by far if you use the 128C one, you just fell in the trap of marketing like Computerbase editor who had to edit his article, he thought that in Intel slide it was 128C vs 128C before some forum members hinted him that it was 64C/128T vs 128C/128T., if they were really competitive they woud have done a 128C vs 128C comparison at same power.

That wouldn't surprise me actually

It's like every single person there was hyperfocused on Strix laptops.
That’s because Strix Point is a winner! Honestly, I am waiting for Strix Halo, but the wait is hard! 🤣

You can thank “AI” for that.

I am pretty sure the memory controller just needs to be able to support LPDDR5. I could be wrong, however.

Can someone elaborate why some here think, that the benches are mysterious?! To me it sounds like massive copium. AMD presented 16% IPC increase so that's that. Do you really think they play 4d chess and suddenly present 25% in july or what?! Sounds silly to me.

We already have, read the thread.
You're free to believe in your copium assessment, ultimately nobody knows until 3rd party benches in a whole 2 months.

Seems like its because of:
1. The choice of benchmarks (They could have gotten a better number with different benchmarks)
2. Errors/mis-matches in the slides.
3. Divergence from benchmarks that they previously used.

Eh. If past history is anything to go by that 16% geomean is just a set of results that fit the Specint NT IPC uplift.

Sure AMD could claim a bigger number with a different suite but then it would not reconcile to spec nt IPC uplift.

Of course just because that is how they did it for prior launches does not compell them to stick to that for future launches and it could just have been a happy coincidence.

If that is the reason, it would be surprisingly and refreshingly honest (ish) marketing. =)

Here we see an average r/ayymd user comments.
It exists in all the other forums, TechPowerUP and Tomshardware. Anandtech forums are the best.

Only problem is the main site is basically on life support. So one day it'll be like Beyond3D and the forums will be a fight for survival, whether to shut it down or not since no money is coming from the main site. So put up with the AI written content or ignore them.
