One of the screenshots shows it's the total package power, inducing DRAM, during a POV-ray stress test. But it doesn't change much since the GPU is at 0 mW (lol) and the DRAM at just 60 mW.
I see at the bottom now. That's very impressive if true as that means total uncore power would only be 0.102 W. That seems almost too low to believe but I don't have anything else to go off of. How much IO does M1 have? Does it support any PCIe lanes, USB, etc?
I guess I should have been clearer in my question. How many PCIe lanes, how much USB, SATA, etc.? I didn't see that in the Anandtech article at least.
Oh, sure. SSDs make launching all apps faster. I wouldn't deny that at all.
Why do you care?
The alternative explanation (that the M1 is really good) is getting pushback in some ways because it's kind of unbelievable. But some of the pushback comes from a different place: the results go against their worldview, so people look for chinks in the armor or ways the result could be invalid because of something else, or something not intrinsic to the M1 to criticize, like the ecosystem.
I think that my one big problem with the M1 is that I still have a ton of old 32-bit Mac software that will not run on it.
Why do you care why I care? If you don't have the answer, that's fine, you don't have to reply to my post.
There is a HUGE range of numbers for BOM estimates for iPhones for the last few generations. SoC cost estimates have ranged from $30 to as high as $70. Obviously the people putting publicly available BOMs together either don't have access to TSMC's actual pricing on leading edge nodes, and/or have wildly different estimates for the yields achieved early in the node's life. I'm sure the more detailed information you can get if you're willing to pay $10,000 to one of the consulting firms that does this sort of thing as their job has better info - but unfortunately we don't get to see that info.
Why would you expect eGPU and multi monitor in Apple's lowest end stuff? I doubt there will EVER be eGPU support for Apple Silicon Macs - all evidence is that Apple will be using their own GPUs across the entire line so why would NVidia or AMD write drivers for the handful of people who might want to use eGPU?
The iPad Pro was probably only refreshed because they wanted to add the ToF sensor so developers could start working on AR stuff for the iPhone 12 release. It didn't improve anything CPU wise other than the 8th GPU core being enabled.
I don't get it. Is he saying that 21 Watts is max core power usage + max 10 Watts GPU = 32 Watts TDP?
I think he's just saying that the full SOC is allowed to use up to 32 Watts if you stress both the CPU and GPU at the same time, there's no limiter preventing it from using that much power (unless you hit thermal throttling). I wonder if you could ever get that high (or close to it) with a real load though. It would need to be a game that can max out at least all 4 big cores and the GPU. Either that or have a game running that maxes out the GPU and doing something in the background that also used a lot of CPU. Would be an interesting test but probably more of an academic type experiment for these devices and the types of systems they are in.
Well, here is my lowly i5-7600 iMac with cached applications. I skipped the applications that had private information but launched the rest of the ones that were in the dock. The lag you see is due to the video recording. The launches themselves were actually quick, but the computer couldn't keep up with the frame rates for the screen recording.
I'm not trying to be sarcastic; I'm tryin to make you think through why you are asking these questions. If you insist on treating these machines as PCs, that you can "rank" by using PC-style numbers, you're going to be frustrated endlessly. You can continue banging your head against a brick wall, or you can listen to those of us with a lot of Apple experience.
My impression so far is that M1 albeit expanded is still a mobile SoC at its heart with comparatively limited I/O.
For those complaining about Chrome on M1, the native version comes out tomorrow.
I pretty much agree fully there. Very impressed with the GPU. I will also say I am extremely impressed with Apple's x86 emulator though, that's a FAST emulator. Clearly a tremendous amount of engineering resources went into that emulator. Clearly a tremendous amount of resources went into the initial software offerings for the Apple ARM platform in general. I do wonder if that same high quality and super-fast code will be the norm, though? Apple obviously had tremendous reason to make sure the debut software was tip-top and super optimized.
The context of his post is in reference to the uncore power, not necessarily to the connectivity and I/O. The answer is, the M1 has very little I/O. No PCI-E lanes, No SATA. It's got a single display PHY (well, not counting the thunderbolt monitor muxing), a handful of USB/Thunderbolt PHYs, Ethernet, single audio port, and that's about it. Desktop SOC from Intel and AMD have 4x the I/O going on, which contributes heavily to "uncore" power consumption. Especially the memory controller needing to drive a fat 128-bit bus across a PCB. These things just cannot be overcome while still retaining the characteristics of a typical PC notebook.
