Discussion Apple Silicon SoC thread

I’m not sure why there’s so much skepticism about the GPU claims. The M1 in Anandtech’s own testing averaged about 39fps in Rise of the Tomb Raider on 1080p Very High. A quick hunt suggests laptops packing the 3070 and 3080 mobile tend to average from 110-130 on the same benchmark. Apple...

Discussion Apple Silicon SoC thread

Andrei made clear on twitter that their preview was pre-written based on the A14 in the iPad Air, and the few details from the livestream (like that slide) were inserted right before publication. Honestly, people have been repeatedly saying that Apple "changed" their claim but there's never been...

Discussion Apple Silicon SoC thread

I must admit it makes no sense to me. The only possible reason to even care about ST performance is because many tasks are not optimized for multiple threads, or else are so sequential they’re run best on a single thread. It’s not too much of a simplification to say that the only two types of...

Haha, indeed it does. I'm an idiot. For transparency I won't edit it above, but 6374*1.36=8669. I should stick to ancient languages and leave math to my betters.

Discussion Apple Silicon SoC thread

I believe @Bam360 is comparing the M1 in the MBP and Mini to the same chip in the Air, where efficiency gains are larger than performance loss when downclocked (correct me if I'm wrong). The implication is that an 8+4 M1X or M2X or whatever with 8 performance cores could theoretically downclock...

Discussion Apple Silicon SoC thread

You make some good points and it’s absurd you’re being downvoted. I knew perfectly well who you were taking about, by the way, and I agree. I do still disagree with you r.e. Geekbench, at least since GB 5 was released. I already mentioned that if you compare GB results with other general CPU...

Discussion Apple Silicon SoC thread

I know some people treat Geekbench or SPEC like they're the holy grail of benchmarks, which is misguided. Apple people tend to focus almost exclusively on GB, while in Windows land everyone is enamored with Cinebench for reasons I can't understand. Linux people are obsessed with all the obscure...

That is fair. Honestly, for that same reason I’ve been trying to wrap my mind around why Geekbench doesn’t unfairly favor Intel and to a lesser extent AMD over chips like the M1. A roughly 30-second benchmark should allow many x86 chips to run at PL2 essentially the entire time, and both Intel...

Discussion Apple Silicon SoC thread

Geekbench has issues and arguably shouldn’t be used as the primary benchmark by as many sites, but I’ve never seen compelling evidence that it actually “favors mobile CPUs”, despite constant claims to that effect. If you read the many, extended discussions on it by Torvalds and everyone at real...

Discussion Apple Silicon SoC thread

I actually agree with you here, my suggestion was that while the M1 might not match the others for raw ST performance (at hugely different power levels, obviously), the efficiency of the M1 is exactly what should set it up to scale so well to more cores and higher raw MT performance. In other...

Discussion Apple Silicon SoC thread

I feel like a lot of the arguments going on here atm are pretty pointless. So here's a little totally unrelated analysis and some handwavey speculation. Big wall of text, my apologies. I feel like much of the focus on the M1 has been on its ST performance, probably because of splashy Geekbench...

Discussion Apple Silicon SoC thread

I have very little use case for it, if I'm being honest, which is why I was agreeing with you. I think the lizard part of my brain wants 8 performance cores, while rationally I have little use for them. I do a few tasks regularly that completely peg the CPU on my 2016 MBP 16" (OCR, bizarrely, is...

Right, sorry, I didn’t mean for the acceleration scenarios you were describing. I meant rather that if one had to choose between improving either general multi-core CPU performance (via an 8+4 variant, thanks @name99) or general GPU performance in a larger M Chip, that perhaps GPU would have...

Spot on. I personally would be all over an 8x4 Apple Silicon CPU in an iMac or MBP16, and I'm sure it would be plenty fast. But at the end of the day, I expect most users would actually benefit more from Apple using all that extra space to massively increase the number of GPU cores, combined of...

Yep, I actually did that same calculation myself. It's a bit hand-wavey but it does suggest the 4800u might still slightly surpass the M1 at the same wattage. Out of curiosity, what's the deal with the 4800u v 4700u and down? Are these just insanely binned parts? They're extremely different...
