> To be fair that $2000 also gets you +32GB RAM, +512GB storage, and +10 CPU cores.

Even though it's not an apples to apples comparison, keep in mind that a 1x32GB DIMM sells for less than 150$, and you can buy 1TB SSDs for less than 100$.

M1 Ultra is 64Gb extra, not 32.

Keep in mind that M1 Pro/Max/Ultra is LPDDR5 6400 (https://www.anandtech.com/show/17024/apple-m1-max-performanc...) connected by a 512 bit memory controller.

Whereas is a kit of 2x 32 GB LPDDR5 4800 (I could not easily locate a quote for 1x 64Gb LPDDR5 4800 DIMM, leave alone 6400) retails for USD 548 (https://www.newegg.com/crucial-64gb-288-pin-ddr5-sdram/p/N82...).

I could not locate a reliable source on the type of the SSD employed in M1 Pro/Max/Ultra, so I will refrain from remarking on the comparison.

I remember a slide mentioning I think “up to 7.4gb/sec SSD read/write speed” or similar, which drastically reduces the pool of comparison SSDs. Intel Optane meets those specs, as do a few other brands I hadn’t heard of previously. In the later case, a 2TB version seemed to be $350-400. Take this for what it’s worth, but SSD is going to be more than $100 extra cost imho.

That's pretty much the speed that Samsung advertises for the 980 Pro: https://www.samsung.com/us/computing/memory-storage/solid-st...

And what WD advertises for the Black SN850: https://www.westerndigital.com/products/internal-drives/wd-b...

And what Seagate advertises for the FireCuda 530: https://www.seagate.com/products/gaming-drives/pc-gaming/fir...

And what Gigabyte advertises for the Gen4 7000s: https://www.gigabyte.com/Solid-State-Drive/AORUS-Gen4-7000s-...

etc...

They aren't $100 for 1TB, no, but a lot of them are around $150. Which would be a lot less than +$100 to go from 512GB to 1TB, too. It's $40 to go from the 500GB SN850 to the 1TB SN850, for example.

I checked the first two and it’s 7,000 read / 5,000 write. Pretty sure Apple said read AND write, which would be a lot faster than those. I might go back and rewatch the keynote, but I still thinking we are arguing pointlessly as Apple has always overcharged for SSD and RAM upgrades vs the price you’d pay elsewhere. Thanks for the DV though even when what I stated was right! ;)

It achieves this speed by not insisting on flushing to disk when requested: https://nitter.net/marcan42/status/1494213855387734019

When configured to ensure data integrity in the case of power loss (more important in this new M1 Studio machine unless it comes with integrated battery), then it's a lot worse.

I have a 8TB M1 Max. It pretty consistently has a max write speed of ~7.3 GB/s and max read of ~5.4 GB/s. No idea why or how write is faster, but that's not a typo.

Their website just specifies read speeds with no mention of write speeds. It's also "up to" and tested on the 8TB models. Assuming it's like other SSDs smaller capacities are usually slower.

HBM2 is a tad more expensive, but yes.

Apple doesn't use HBM2, so not really relevant

Correct my bad. GDDR6x is still more expensive then GDDR4 you get with Thread ripper.

Apple isn't using GDDR6X, either, nor does threadripper use GDDR4.
