But when were the first two slides published? Was it 1-2 months before Zen4 release, like for Zen5 at Computex now, or earlier?Sandbagged Zen 4 prior to release:

Real Zen 4 (released):

+14% headroom in clock speed (5Ghz+ versus 5.7Ghz on launch)
~8% IPC (early reveal) vs 13% on launch.
>15% ST uplift turned out to be ~29% ST uplift.
You're welcome.
I've posted that in the past but AMD got a long history of flopped "major architectures".If 16% is accurate for 1T workloads as well then AMD have gained less than Intel from the same kind of changes. That would not be great, especially with ARM based architectures showing good gains.
It was roughly 1 month before release if I remember correctly.But when were the first two slides published? Was it 1-2 months before Zen4 release, like for Zen5 at Computex now, or earlier?
Quite some differences. I wonder what the purpose of the intentional sandbagging is.+14% headroom in clock speed (5Ghz+ versus 5.7Ghz on launch)
~8% IPC (early reveal) vs 13% on launch.
>15% ST uplift turned out to be ~29% ST uplift.

These slides were released 4 months before release, not comparable to Zen 5.It was roughly 1 month before release if I remember correctly.
Exactly.But when were the first two slides published? Was it 1-2 months before Zen4 release, like for Zen5 at Computex now, or earlier?
So sandbagging is not real in Zen 4 case because it was 4 months before the release? LMAOThese slides were released 4 months before release, not comparable to Zen 5.
Let's wait and see then.Exactly.
This is what was announced: https://www.anandtech.com/show/17552/amd-details-ryzen-7000-launch-up-ryzen-7950x-coming-sept-27
7950X release did not deviate from that.
We now have 9950X announced, and a month out from launch. Expecting that AMD is sandbagging this close to release is hopium.
Agreed. I hope itβs an amazing part.Let's wait and see then.
I wonder what's the lowest you'll be able to get an STX Halo laptop for. $2000+ laptops?AMD laptop CPU roadmap with Zen5 X3D + more:
(Link above also has roadmap for Intel mobile and Nvidia.)

$1000 is too low even for STX1, let alone STX Halo ig. You're not getting 16 cores, 4 memory channels and a 6700XT-sized APU for $1K, that's impossible.AMD 100% aims strix halo for portable / steam deck 2 / playstation 6 etc
it's the ultimate gaming APU
laptops probably $1000-2000 depending whether extra dgpu or not
No, it's a Very Premium Thing.AMD 100% aims strix halo for portable / steam deck 2 / playstation 6 etc
Yeah, but it's still should cost reasonable enough money if they have enough design volume.You're not getting 16 cores, 4 memory channels and a 6700XT-sized APU for $1K, that's impossible.
Model number, core count, base and peak clocks, TDP, cache sizes, supported memory speeds, and the month of launch were disclosed. Together with fuzzed performance data.We now have 9950X announced, and a month out from launch.
SMT scaling being lower would imply that they've removed some bottlenecks that previously stalled the hardware thread or otherwise left it unable to utilize the core to a greater extent.
The slides AMD shared had a lot of MT workloads in the 16% claim but the gaming slides are already indicating a larger gain than that IPC figure. They put Zen5 a tiny bit ahead of the Zen4 X3D which indicates a ~25% performance uplift in gaming.
Immediately something does not mesh so with that in mind I am waiting for Anandtech to do the SPECint 2017 1T tests to work out the IPC uplift in that benchmark. If it is less than 32% then adroc/Kepler were unambiguously wrong, if it matches or exceeds they were correct.
Given the gaming uplifts it suggests the 1T IPC uplift is greater than nT which is something that adroc has said.
Also, AMD sandbagged hard with Zen4. Pre reviews it was looking like it would be a lot slower than Z poen3X3D in gaming but it was actually on par and is now frequently ahead by a small margin.
So a long way of saying wait for benchmarks if you want definitive answers. In the interim just have fun, there is no need to lash out at people, it is just a tech thread, it is not that serious.

Also no direct comparison with 7000 series models, no ST uplift, no performance/watt numbers (which should be massively in favor of Zen 5).Model number, core count, base and peak clocks, TDP, cache sizes, supported memory speeds, and the month of launch were disclosed. Together with fuzzed performance data.
Launch date, MSRP, SPEC performance, PPT limit, and more details however are still top secret.
And they are even more secretive about server parts. Whose core microarchitecture is being reused in client parts.
MacBook Pro pricing at the lowest then, I guess (so $1600+).Yeah, but it's still should cost reasonable enough money if they have enough design volume.
Go be annoying elsewhere.
The official canon is Phoenix times 1.16 until proven otherwise.
They can go lower, the pitch is replacing APU +dGP combo with something sleeker and cheaper.MacBook Pro pricing at the lowest then, I guess (so $1600+).
And what's the significance of A0 silicon?Would this generation be so special? AMD decide to release high performance DT chips GraniteRidge A0 silicon to consumers
It seems that a lot of Strix Point laptops are coming with NVidia dGPU. So since Strix Halo is dropping the dGPU, the increment is going to be less, since the OEMs will be dropping the NVidia dGPU.I wonder what's the lowest you'll be able to get an STX Halo laptop for. $2000+ laptops?
