Speculate at will

PRO SKUs for Dragon Range?

The EPYC doing EPYC things


Think my 8700 profile is done 👍

So the delidding helped the IMC???

Temps always help IMC, but the gain from 8500 to 8700 mostly comes from me discovering it likes high CLDO_VDDP
CLDO_VDDP = 1.15v -> max karhu stable was 8500
CLDO_VDDP = 1.2v -> max karhu stable was 8700

Wouldn't synchronizing UCLK to FCLK deliver better performance?

Problem is that even non glass phones are often glued instead of using screws. Everything so the phone is as thin as usb port itself, which for me is completely misplaced goal as neither it makes it easy to hold nor it makes it easy to cool. But that is a separate story. Still, would anyone buy a phone without integrated battery, having to use back attached power bank to act as one? Yes, the device is thinner in theory, but in practice is even bulkier.

sarcasm carries poorly over internet it seems...

Apparently, you missed that my tongue was firmly planted in my cheek as well ... 😂

Strix Halo is coming to handhelds, people.

That's goofy as hell. AMD could have made a much better semicustom product, probably for less with the right volume.

 

[coercitiv]

That's goofy as hell.

It's not goofy at all, they're all experimenting. It's a good thing.

Not really? Strix Halo is a known quantity. What exactly is the experiment?

suspicious as hell. the third digit is Zen generation, so "9945" indicates zen 4.... double-rebadged zen 4 7945hx?

bruh what the hell

 

[coercitiv]

Yes really. Strix Halo is an experiment for AMD, they're testing the waters. The same applies to handheld makers, they're tempted by the capabilities of the product and willing to experiment despite it's obvious drawbacks.

Moreover, Strix Halo is such a known quantity that up until a few days ago you didn't even know it had a single CCD SKU.

Oh yea. now you mention it... Unless it's Desktop SKUs. But this tweet:

AMD Threadripper 9980X + 9970X Linux Benchmarks: Incredible Workstation Performance Review - Phoronix

Phoronix Benchmarks for non-PRO TRs

So far I have ran more than 200 different workloads on the AMD Ryzen Threadripper 9970X and 9980X processors as part of this testing for launch day

Those wanting to see all my raw performance and power data for this launch day review can see this result file for the 220+ test results in full.

When taking the geometric mean of all the raw performance data points in full, going from the Threadripper 7980X to 9980X yielded a 30% improvement. For a single generation.

Thanks to AMD for providing the review samples for launch-day Linux testing at Phoronix. I am already working on several more follow-up articles around the Threadripper 9000 series Linux performance for publishing in the coming days and weeks.

His geomean results put 9980X as +30% over 7980X. Very interesting as it should have similar clocks as the 7980X. This holds true for 9970X vs 7970X as well (+28%). Whats accounting for the additional +14% overall perf over the claimed +16% IPC?

Another contributing factor may be the memory speed of the test systems:
7980X DDR5 4800
9980X DDR5 6400

Yeah and I bet that Shimada Peak is still underperforming. Maybe what it really needs is 8800 MT/s MRDIMMs.

11% PPW from N5->N4P

 

[adroc_thurston]

11% PPW from N5->N4

That's just not real.

 

[jpiniero]

That's just not real.

TSMC claimed 22% power reduction or 11% more performance from N5 to N4P.

 

[511]

That's just not real.

As the third major enhancement of TSMC’s 5nm family, N4P will deliver an 11% performance boost over the original N5 technology and a 6% boost over N4
So TSMC is lying?

TSMC Expands Advanced Technology Leadership with N4P Process|Taiwan Semiconductor Manufacturing Company Limited

Hsinchu, Taiwan, R.O.C., Oct. 26, 2021 - TSMC (TWSE: 2330, NYSE: TSM) today introduced its N4P process, a performance-focused enhancement of the 5-nanometer technology platform.

And somehow this doesn't help Granite Ridge, merely Shimada Peak?

I agree with Adroc here. Do we have any evidence Zen 5 is clocking 11% faster at the same power draws as Zen 4? Because thats what this would imply.
