Discussion Zen 5 Speculation (EPYC Turin and Strix Point/Granite Ridge - Ryzen 9000)

Oh, so it does look like I have reason to be skeptical and disappointed with Zen 5.

Is this because Intel said they would release their microcode update also on August 15th... *rubs chin*

Only means AMD isn't confident it can comfortably beat the competition without gimping.

I wonder if Youtubers like GamersNexus etc noticed a problem and let AMD know? Either way, better now than a full recall later. It's just two weeks, no lifes will be lost.

I’m gonna be honest that should up to AMD to test, find and fix. If an YouTuber found an issue and let them AMD know what does that make of AMD’s QA team? Incompetent?

Well... if they catch it before launch they're about 640 days ahead of the x64 competition.

But I wonder what they weren't testing previously.

Pure speculation, but from the statement, and what we've seen from ES samples, and the fact that the top SKUs are affected more, I would guess hitting spec clock speeds (5.7/5.6 GHz for 9950X/9900X). Maybe some of the retail units only hit 5.5 GHz or so.

They said that it was about what could be obtained at stock but the chip was under LN2 when they got this number.

Looking at the 55046 pts score at 6.375Ghz then those 42k were performed at 4.86GHz, beside the alleged 7 Zip 214,113 score is only 3.83% better than the 7950X, wich lead me to think that those numbers are not what we ll see in reviews.

The 7950X 7 Zip score can be found here, it s 206,214 :

It's still stock, just a non-thermally limited one (and slightly more efficient operating condition).
 
My best guess is that the Yields just aren't there. 5.4 and 5.5GHz kinda works, so the 2 small SKUs can Release on 8th, but the number of 5.6 and 5.7GHz CCDs is so low that it would've been a paper launch. That's the only reason I could imagine where this launch window makes sense.

However, this whole launch already has been a mess. Official Presentation without proper launch Date ("July") and price. Then they drop the Date (last day of July lol) 2 weeks before. It's a wednesday too, usually AMD does Thursday launches, the new dates are thursdays too, what a coincidence. There's a 90% chance in my eyes, that 31st already was a delayed date and they took the last day of the month and hoped they would somehow get them out by then. We also still don't know Official prices. You can tell me what you want, these CPUs were/are far from ready to launch. There's so many red flags during these last 2 months.

I doubt that. Having out of stock products for a few months has never been an issue before.

That s not a more efficient condition, rather the contrary since mosfets are slower at very low temps, the higher the temp the more the transconductance up to a given temp, generaly in the 100-120°C range, at wich the conduction and speed at a given voltage start to decline, it s just that under LN2 you wont overheat the chip with a hugely over specced TDP.

Actually at -100°C you need to pump higher voltage to reach the same frequencies than at 50°C, and as already said i dont believe that the 9950X has only 3.85% better 7 Zip perf than the 7950X, this very number just doesnt make sense.

Edit : Methink that in reviews the CBR23 score will be up to 10% higher and the 7 Zip one 15-20% higher, AMD stated perf improvement over the 7950X is 22%.
