OpenAI is right now the premiere AI company in silicon valley. Why are they giving all their employees Macs and not Windows laptops with Intel and AMD chips?

They're also running their actual compute on x86 (+ Nvidia) platforms...

Anyway, Macs have been popular with programmers since well before the switch to Apple Silicon. They're a native Unix environment in a (typically) premium device. Apple Silicon is great, sure, and Intel/AMD face competitive pressure to close the gaps, but it hardly invalidates them overnight.

Seeing as how my 96 core Genoa was beat by an Alderlake something CPU mul multicore, I am not even going to bother trying it, due to this comment "and multi-core scores to be raised by up to 10%.".

Now if they said by 2000% or something I might get excited.

Yeah, that's just plain silly. Either stop pretending it's reflecting a CPUs (instead the test case's) multi-core performance, or change it to something embarrassingly parallel.

But I'm sure many people now are happy GB 6.1 improved their chip's multi-core performance...

You almost made it sound as if multi-core performance is only measured by embarrassingly parallel tasks. If it's what people want, then they should use some rendering or parallel compilation benchmark.

Or focus on the subscores of GB that show how these tasks scale:

  • ray tracer: x19
Looks like good scaling for a 16-core CPU.

Thing is we don't have enough information about bottlenecks (are these due to a benchmark issue [implementation or just inherently not scalable] or a CPU issue?).
All I could find was this: https://www.geekbench.com/doc/geekbench6-cpu-workloads.pdf and it doesn't tell anything about the MP aspects.
That's not GB specific, all closed source benchmarks suffer from that.

And another issue is that scaling changed dramatically between GB 5 and GB 6. And I personally think it's a good thing as GB 5 scaling didn't mean anything to me.

:joycat:

The problem is some think a single aggregated number can represent a CPU performance. And definitely GB 6 MP number doesn't. Like any other benchmark.

For a simple refresh the gains are quite nice, though I hope GB7 brings a healthy generational +25% ST performance uplift! :D

For a benchmark this just means that the results of the previous version cannot be compared with the results of 6.1. The title of this news piece is pure trash.

MT scaling is still abysmal. The core issue of GB6 being "I prefer this particular CPU with its very limited number of cores, and I don't care about any additional cores people may have" remains. And this particular CPU may very well be the basic Apple M1 (4P+4E cores).

And there's a regression, bravo John Poole! The Navigation test is now slower than in v6.0.

Yes, in real life MT scaling often is abysmal. Look at subscores for things you're interested in rather than focus on the global score; see my other post above, some of the tests scale quite well.

1. No one will compare subscores.
2. GB5 scaled near perfectly.
3. GB6 strongly, stubbornly, to its death even prefers very particular very limited core configurations - well, that's not a MT benchmark, that's John Poole's benchmark. Remove the "MT" mark from it and people like me will be fine.

We've had 11 pages to discuss this and the consensus has been reached. I don't understand why you wanna argue again.

I will continue to dismiss GB6 "MT" results with prejudice. Considering this peculiarity I'm not inclined to trust its ST results either. GB5 was known to demonstrate very tangible and straightforward differences between systems. GB6 turns everything upside down.

tl;dr it models multithreaded workloads more realistically, hence why multicore scores are lower.

Perhaps a better way would be to show both scores so users have a good idea of both theoretical and actual multicore performance.

And this has been discussed here as well ad neouseum. There are a dozen ways to limit MT performance (including and not limited to memory performance; inter-core communications including inter-core latency; cache size; threads synchronization, etc), GB6 uses just one of them and calls it a day. Good. Fine. Excellent. Now is there a single mention of that on the website? In the program? Anywhere?

When you offer a universal multi-threaded benchmark (which, surprise, surprise GB5 actually was) you make sure it scales. GB6 MT almost does not scale beyond a certain number of cores.

If you're extremely interested in certain "realistic" workloads which scale poorly, you bench them yourselves. You don't go around screaming "My particular workload means 128 core EPYC systems are complete crap and a waste of money!" which is exactly what GB6 MT does, 'cause you know Apple matters!

Now compare this to GB5 MT:

Can you find Apple M2 Ultra, no? It's at the rock bottom.

It is kind of amazing to me that even after the A9's massive 70% performance jump in a single year, since then Apple has managed to go a full 5x faster in only 8 years in ST performance. That's despite their rather lackluster gains the last few years.

That almost seems too good to believe...was that 599 throttling? Is yours the TSMC or Samsung chip?

Phones don't unlock more performance for being on the charger LOL. It is the other way around, they can throttle more because of the heat generated by charging.

It didn't seem hot so I'm sure it was fine. No easy way to check the chip type. There used to be some battery monitor app that revealed the CPU codename but that's not available on the app store anymore.

Seems you are right, with respect to the iPhone 6S Plus only. On charger, it delivered 521 ST and 485 MT. The Moto Edge 30 seems to not get hot enough with the charging so there is no throttling and it even improves the score.

I turned on the AC, took the iPhone out of the case, stood it up with support at a place where the cold air from the AC was flowing above and ran the test again. This time, it managed 635 ST and 964 MT. Did the same thing for the Moto Edge 30 and this time, it underperformed with 1063 ST and 2998 MT. Maybe it doesn't like being cold :)

1.85GHz for the A9 and 4.05 for the M3, that s 2.19x the frequency, guess that a similarly clocked A9 would be still quite competitive currently even if not high end.
