It scales fairly linearly.
985@2.3G
858@2.0G

There are some variations but these are best cases for my chip

Yeah, only 0.17% error between linear extrapolation and actually setting it to 2.3 GHz. That means the results are indistinguishable, so no need to actually run when the frequencies are so close together. Thanks for confirming though.

Here's the H2H comparison with the 2.3GHz bench for anyone interested. Perf is all over the place, there are some regressions, whereas some other tests show obscene gains.

As said previously, it's pretty pointless to draw any conclusions from those.

Some stats about Strix, nothing earth-shatteringly new:


One interesting dibit is that Strix Halo still has full 32MB of L3 per CCD, so these look more and more similar to Granite Ridge CCDs

Oddly, Strix Point seems to cap out at LPDDR5x-7500, while Halo supports up to LPDDR5X-8000 memory (256-bit bus),
Also from that article:
1714070394246.png
So what do we make of that?

1. Fire Range == Granite Ridge, and with same IOD (inherited from Zen4 DT, thus only 2 CU RDNA2 as in table).
Also, no NPU on either. So both are DOA for Win12 requirements (which are NPU with 40+ TOPS NPU), unless adding separate NPU or GPU via PCIe.

2. Strix Halo == Granite Ridge, but with different IOD.
And STXH IOD contains 40 CU RDNA 3.5 + NPU? So for those intending to run at ~105W TDP for CPU and without GPU, STXH will be a better option than GR. They'll perform the same in CPU perf tasks at same TDP, but STXH will have much better iGPU and NPU. So essentally STXH based SFF PCs will have better feature set and will outperform GR DT PCs in non-CPU bound tasks.

PS. FR & STXH are of course also in mobile packaging, with lower TDP and frequencies, at default settings. But if running FR & STHX at 105W, and GR at the same via ECO setting, then CPU bound perf should be the same.

Don't need the tumor on rebate-insesitive luggages.
MS sets the requirements for TPU whether you like it or not. Those that do not comply are DOA for Win12. Same as with TPM for Win11. There might be workarounds, like for Win11 w.r.t. TPM, but that is uncertain and in any case not ideal.
It is NOT.
Bespoke CCD.
So in what way specifically do the CCDs differ on Granite Ridge vs Strix Halo (16C variant)?
Different uncores and memory setups.
You are comparing what to what? Strix Halo, Fire Range, Granite Ridge, ..., to what?

And specifically, what differs regarding uncore and memory setups? Too vague just stating like that.

You don't know how it works why are you arguing that with me.

I do know, and it's like I stated previously w.r.t. Win12 NPU requirements. If you think differently, clarify and provide evidence.
Read the thread.
I've done that. No details found. If you have some, clarify or link to previous post explaining it.

You never answered this ^^^.

You don't.
Please stop.
You're looping. If you don't have any evidence of your claims w.r.t Win12 NPU requirement not being valid, just say so.
Improve your reading comprehension.
So there wasn't anything backing up your claims. Otherwise you could have simply linked to it or clarified, but you didn't. So essentially you have no info on that "CCDs differ on Granite Ridge vs Strix Halo (16C variant)" that you claimed. Got it.

You never answered this ^^^. Second reminder. I take it your claim was not correct and/or you don't know. If you avoid answering it a third time I take it as conformation of that.

You don't understand what the requirement is.
It's just a sticker.

No one's gonna spoonfeed you, kiddo.

TPM requirement for Win11 was also just a sticker?

Read.
So your claim was all BS, since you couldn't even link to any previous post clarifying your claim that you said existed. Got it.

Third reminder regarding this without answer ^^^. Your statement is debunked.

And the same article says also it requires a copilot key on the device. I somehow get the impression they were only talking about subsection of the requirements given the best Windows ML performance comes from devices without a built-in keyboard.

And maybe Microsoft will add that dedicated copilot key to their own Surface Pro tablet too?

What will you say about LionCove having 18 execution ports? For Integer 14 ports including 6xALU, 6xAGU and 2xSD. The FPU(?4x ALU-FP?) has 4 separate execution ports.

4-Way predictor, at least 8-Way decoding, sending from UOP cache at least 12, 8-Way dispatch/rename.

Skymont 3x 3-Way decoding.

The last 100 pages or so are someone with knowledge answering questions from you and these responses either treating them in bad faith or not reading what's being said. It's tiring.

Because someone can't answer your nonsense questions in infinite detail, doesn't mean there's a genius at play and you've found something out. Read the info.

Back on topic. Zen 5 is bonkers. You heard it here second.

45 TOPs NPU/System hard requirement for W11 24H2 AI PC experience and devices marketing and rebate.

Co-Pilot Key is optional but being pushed by MS.

Devices without 45 TOPs NPU won't get PC AI experiences. There will also be a watermark on non-AI PC indicating no Explorer AI/AI PC capabilities. To be seen if they'll allow it to be disabled or give up on the idea.
