> it can be configured up to 512GB, or over half a terabyte. Hah, I see what they did there.

If they added 1 byte, it counts.

The "what they did here" part is they mean base-10 terabytes, and 512 GiB = 512·1024^3 bytes is indeed strictly more than 0.5 TB = 500·1000^3 bytes.

Chip? Yes. Product? Not necessarily... It's not completely out of the question that the 512gb version of M3 Ultra was built for their internal Apple silicon servers powering Private Compute Cloud, but not intended for consumer release, until a compelling use case suddenly arrived. I don't _think_ this is what happened, but I wouldn't go as far as to call it impossible.

That's absurd. Fabing custom silicon is not something anybody does for a few thousand internal servers. The unit economics simply don't work. Plus Apple is using OpenAI to provide its larger models anyway, so the need never even existed.

Apple is positively building custom servers, and quantities are closer to the 100k range than 1000 [0]

But I agree they are not using m3 ultra for that. It wouldn’t make any sense.

I miss the XServe almost as much as I miss the Airport Extreme.

I feel like Apple and Ubiquiti have a missed collaboration opportunity on the latter point, especially with the latter's recent UniFi Express unit. It feels like pairing Ubiquiti's kit with Apple's Homekit could benefit both, by making it easier for Homekit users to create new VLANs specifically for Homekit devices, thereby improving security - with Apple dubbing the term, say, "Secure Device Network" or some marketi…

HomeKit networking existed in Eero briefly. I put that in a lot of casual Apple homes. Seemed like missed oppty for Apple to let Amazon buy Eero, a more "spiritual successor" to the Airports.

Still cheap if the only thing you look for is vram.

This chip has 0GB vram. It has 8 channel lpddr5.

This is not correct. It is like VRAM, not like normal PC RAM.

Lowest latency of DDR5-6400 on normal PC starting at 60ns+

Lowest latency of VRAM on GeForce RTX 4090 starting at 14 ns

Lowest latency of Apple M1 Memory starting at 5 ns, its more like L3 cache

And on Apple M chip, this ultrafast memory is available for CPU, GPU and NPU.

Some possible groups of reasons: 1. Until recently RAM amount was something the end user liked to configure, so little market demand. 2. Technically, building such a large system on a chip or collection of chiplets was not possible. 3. RAM speed wasn't a bottleneck for most tasks, it was IO or CPU. LLMs changed this.

M1 came out before the LLM rush, though

Apple debuted dedicated machine learning hardware in 2017 with the Neural Engine on iPhones. While I don’t think they predicted the LLM explosion in particular, they knew machine learning was important and they have been allowing that to influence hardware design.

Can anyone with older Mac Studios/Minis comment - do you also notice a "throttling" of the hardware? I'm not sure if this is me not maintaining it properly (e.g fans having dust block them) - but I've always got this sense that Apple throttles their older devices in some indirect ways. I experience it the most with iPhones - my old iPhone is pretty slow doing basic things despite nothing really changing on it (just t…

> (just the OS updating?)

"Just the OS updating" is not insignificant. Software developers, in general, are not known for making sure latest versions of their software run smoothly on older hardware.

Also, performance on iPhones is throttled when your battery is very old. There was a whole class-action lawsuit about it.

I actually think it’s not a coincidence and they specifically built this M3 Ultra for DeepSeek R1 4-bit. They also highlight in their press release that they tested it with 600B class LLMs (DeepSeek R1 without referring to it by name). And they specifically did not stop at 256 GB RAM to make this happen. Maybe I’m reading too much into it.

$10k to run a 4 bit quantized model. Ouch.

That's today. What about tomorrow?

if that were the case, then it would definitely help Apple Intelligence if the iPhone and Mac had higher amounts of RAM, but the base MacBook Pro announced by Apple a while ago had 8 GB of RAM and even the pro versions of the iPhone have 8GB whereas 12, 16, or even higher RAM is very common in android devices which helps users run relatively large language models on their devices

All iPhone SoCs made after ChatGPT launched start with 8gb, and all Mac SoCs start with 16hlgb

that's just not true:
