In a laptop, I care far more about battery life and the fan noise. However, Intel 12th gen is only able to pull these impressive performance feats due to very high turbo boost clocks. It's not that Intel is bad, it's still pretty great but in the age of M1 I wish Intel released a processor with similar power consumption. I use my Intel i5-1240p with turbo boost disabled when on battery. Here's the geekbench with TB d…

As do I.

Meanwhile in a server, I'm starting to worry that as I work to flush performance issues out of the system, especially latency problems, that I won't see the sort of perf numbers I'm expecting because the fact that the machines are running well below 50% CPU utilization are likely to dogleg the moment it hits the thermal limits, and I have no way to predict that, short of maybe collecting CPU temperature telemetry. Not only might my changes not translate into 1:1 or even 1.2:1 gains, they might be zero gains and or just raise the CPU utilization.

Magical CPU utilization also takes away one of the useful metrics for autoscaling servers. Thermal throttling opens the door to outsized fishtailing scenarios.

AMD processors provide PCIe lanes, some of which are intended for use with NVMe SSDs but nothing on the chip actually implements or understands NVMe and the lanes used for the SSD in a typical system design are still fully generic PCIe lanes.

> nothing on the chip actually implements or understands NVMe pretty sure that's false as well... can an X300 system boot a NVMe drive? I'd assume yes. It does that with a UEFI which lives... where? Oh right, on the chip. Most NVMe SSDs don't provide legacy option roms anymore either.

No, UEFI is firmware stored on a flash chip on the motherboard, usually connected to the CPU through the LPC bus. CPUs do not have any nonvolatile storage onboard (unless you count eFuses).

When depending on solar it’s pretty important to be low power, m1 drawing 10-20 watts vs something else drawing 60-80 can make a big difference on batteries

The reality distortion field of apple fans is really getting out of hand. Portable laptops (i.e. not the desktop substitude game machines) have not been using 60W for years. In fact my X1 from 2016 typically shows between 6 and 15W in powertop depending on load and has been lasting >8h on linux (it's less now as the battery has aged a bit).

I meant the controller that manages the NAND cells, I assumed it would be called NVMe controller. Essentially the IC that the "NVMe controller" in your image talks to.

That would normally be called a "flash controller" and yeah, of course that lives on the SSD. (unless it doesn't - eMMC doesn't normally have a flash controller and you just do direct writes to the flash cells... as do some IOFusion PCIe cards that are just flash directly attached to PCIe with no controller. Sometimes that functionality is just software-based. Flash cards (eg microSD) usually also do not have a flash…

Youve taken a lot of liberties and assumptions with my post here. I dont do any of those things you mentioned, only enforce a nightly shutdown. Nothing to do with laziness. As other people have often mentioned on HN, in the real world of understaffed underbudget corporate IT you need to do what you can to enforce things which make everybodies life easier.

"everybodies life easier"

I don't think this means what you think it means. I'm not a dev, but a mechanical engineer, and having to shutdown nightly, and reopen things the next morning, would cost the company at least an hour of my work time every week.

Apple uses NVMe. It's just not over PCIe. It uses a proprietary mailbox interface. Which is fine since NVMe is transport agnostic.

> AMD was absolute garbage for like 10 years until around 2016 Their top performance was lower than Intel in many cases, but it was certainly not "absolute garbage". For low- to mid-range they offered similar performance with usually a (much) lower price point. For normal "average person" usage they were often the better choice in terms of "bang for your buck". The main reason we were selling Intels is because we got…

Well okay. But they had the same problem Intel is in now: they pushed an inefficient power hungry chip to the limit. So it was cheaper, and performance was only somewhat lower, but it was much hotter and used a lot of power —- so pretty useless for laptops.

On laptops AMD was indeed not very good; but their desktop CPUs – far more important in the 00s and early 10s than they are today – were pretty decent. That is not to say that Intel also didn't have good CPUs at the time, but (much) more expensive and for people just doing their browsing and occasional gaming on their desktop AMD was a solid (and cheaper!) choice IMO.

FYI, all current flash card formats have the equivalent of an SSD controller, implementing a Flash Translation Layer. Exposing raw NAND was somewhat viable in the very early days when everything was using large SLC memory cells (see SmartMedia and xD-Picture Card), but no current format could remain usable for long without wear leveling. If you can use standard filesystems and access the drive or card from multiple operating systems, then it must be providing its own FTL rather than relying on the host software for wear leveling.

The above also applies to eMMC and UFS storage as found in devices like smartphones.

Surely the real story here is that Framework have released a CPU upgrade for a laptop?

Yep! We released an announcement around starting shipments of this two weeks ago. Our blog post this week was just a round-up of benchmarks both from reviewers and from us, to respond to common questions we got around performance improvements.

What's the plan to open the region in New Zealand?
