New 12MP Center Stage Camera. Will it support 4k?
I don't think so. They would have made that a huge deal.

#112> while protecting their privacy This is misleading: https://news.ycombinator.com/item?id=25074959 "macOS sends hashes of every opened executable to some server of theirs"
What's the deal with running Linux on these anyway? Could one conceivably set up an M4 mini as headless server? I presume Metal would be impossible to get working if MacOS uses proprietary drivers for it...

The M3 Max was 400GBps, this is 540GBps. Truly an outstanding case for unified memory. DDR5 doesn't come anywhere near.
It's not "DDR5" on its own, it's a few factors. Bandwidth (GB/s) = (Data Rate (MT/s) * Channel Width (bits) * Number of Channels) / 8 / 1000 (8800 MT/s * 64 bits * 8 channels) / 8 / 1000 = 563.2 GB/s This is still half the speed of a consumer NVidia card, but the large amounts of memory is great, if you don't mind running things more slowly and with fewer libraries.
Thanks, but just to put things into perspective, this calculation has counted 8 channels which is 4 DIMMs and that's mostly desktops (not dismissing desktops, just highlighting that it's a different beast).
Most laptops will be 2 DIMMS (probably soldered).
Re: M4 MacBook Pro
#114What’s amazing is that in the past I’ve felt the need to upgrade within a few years. New video format or more demanding music software is released that slows the machine down, or battery life craters. Well, I haven’t had even a tinge of feeling that I need to upgrade after getting my M1 Pro MBP. I can’t remember it ever skipping a beat running a serious Ableton project, or editing in Resolve. Can stuff be faster? Tec…
I've owned an M1 MBP base model since 2021 and I just got an M3 Max for work. I was curious to see if it "felt" different and was contemplating an upgrade to M4. You know what? It doesn't really feel different. I think my browser opens about 1 second faster from a cold start. But other than that, no perceptible difference day to day.

I don't think you understand what a press release is.

#117If I remember correctly, the claim was that M3 is 1.6x faster than M1. M4 is now 1.8x faster than M1. It sounds more exciting than M4 is 12.5% faster than M3.
Maybe they are highlighting stats which will help people upgrade. Few will upgrade from M3 to M4. Many from M1 to M4. That's my guess.

#118Can someone please help me out with this? I'm torn between Mac mini and and MacBook Pro, specifically the CPU spec difference. MBP: Apple M4 Max chip with 16‑core CPU, 40‑core GPU and 16‑core Neural Engine Mac mini: Apple M4 Pro chip with 14‑core CPU, 20‑core GPU, 16-core Neural Engine What kind of workload would make me regret not having bought MBP over Mac mini given the above. Thanks!
For normal web dev, any M4 CPU is good as it is mostly dependent on single core speed. If you need to compile Unreal Engine (C++ with lots of threads), video processing or 3D rendering, more cores is important.
I think you need to pick the form factor that you need combined with the use case:
- Mobility and fast single core speeds: MacBook Air
- Mobility and multi-core: MacBook Pro with M4 Max
- Desktop with lots of cores: Mac Studio
- Desktop for single core: Mac mini
I really enjoy my MacBook Air M3 24GB for desktop + mobile use for webdev: https://news.ycombinator.com/item?id=41988340

It's not the memory being unified that makes it fast, it's the combination of the memory bus being extremely wide and the memory being extremely close to the processor. It's the same principle that discrete GPUs or server CPUs with onboard HBM memory use to make their non-unified memory go ultra fast.
I thought “unified memory” was just a marketing term for the memory being extremely close to the processor?

Most people buying a new MacBook don’t have the previous version, they’re going much further back. That’s why you see both intel and m1 comparisons.
