What type of compression could we expect from plotting 13X times? Why 13???
Thatâs how DrPlotter works. You look for multiple proofs with the same Y value, in this case 4.
Mac is a really evil choice, given how bloody expensive they are and how uncommon.
when we think about it, does this really work?
could this be the reason why netspace is not dropping?
Not sure where youâre looking but netspace has been steadily dropping since March when it was about 34 EiB and now itâs around 18, with the general trend downwards.

We are planning for the future. The next gen Mac laptops should be able to grind if they are available with 192GB like the M2 Ultra. Many users will already have a Mac laptop on hand in that future (Intel is dying).
DrPlotter is not efficient.
The Mac Studio M2 Ultra can spoof a little over 7 PiB of hard drive space in a small efficient and quiet package.
Not too bad, but I better not check what these puppies cost xD
Doing some basic math:
DrPlotter Pro4x takes ~250 ms per âgrindâ on a 4090, ie. per plot passing the filter. Thatâs with on-disk storage of 200 TB per 4090.
Now you claim to do a full grind in ~33 ms on a M2 Ultra, which is comparable to a 4070. So about 10x faster, without any storage (well we donât know how big this file is that we need to download).
It doesnât add up, on one hand you need massive VRAM (~180G) but on the other your computation is really fast. Assuming 800 GB/s, just writing 180 GB to VRAM once without reading it back would already take ~225 ms.
Realistically, a full grind would already be very fast if you can do it in 10 sec on that M2 Ultra. So if your numbers are true, youâre somehow getting a ~300x increase in win chance.
You can pick up some used deals on eBay, or buy a edu email account for a academic discount. Note the new plot format is much smaller so we wonât need 192GB in the future to âgrindâ (we arenât grinding technically xD)
Honestly, the total system efficieny is much lower, and will dictate download pricing. We will not be using FPGAs for cloud initializing by launch time. I donât really want to invest any money into hardware at this point giving the low price of XCH. We are now able create the files for download on demand using H200 instances. You can rent them for about a $1.50 per hour now off peak.
Did you check the pricing for egress lol?
If this is on AWS or GCP, the cost to download the files will be massive. So they better be small, like 100 GB per Mac.
It is?
Yes correct, if it involves a pre-compute step with storage, itâs not grinding. Unless itâs to find plot IDs that pass multiple signage points, but thatâs kinda trivial, at least for 2x. Even 3x should not be a big cost.
2 PB netspace drop in the last month or two, 5 since August =/ âitâs not droppingâ.
Itâs been dropping SLOWER as someone has been supporting the price more-or-less around the $15 level, but the drop HAS continued.
Planning for the future does not equal âonly support a proprietary format LITTLE USED platform that is way expen$ive and almost nobody can AFFORD to use,â
Also, the future has already been indicated to include a complete plot format change that will be much more resistant to âcompressionâ techniques.
Intel is not the only major X86 maker, and itâs not going to die in the next couple of years - and probably not in the next couple of decades.

I have a Mac Studio M1 Ultra with 128gb of RAM. Can I grind anything?
You better go quick an spend 8k on a new M2 Ultra 
Before they out of stock⌠(Iâm just kidding, not financial advice)
haha - I was just browsing eBay now for them. Looks like I can snag one for a mere $5k
Donât forget, needs to be one with 192G RAM/VRAM. Not the 64G or 128G models.

Yeah there are a handful of the maxed out models on eBay now. Not ready to drop 5k until it can be proven to grind 7 PiB of plots. 
Itâs also unknown what GrinderPro will charge for their âfilesâ, might be a couple grand per device, who knows.

How much would 1 PiB of HDDs cost? Letâs figure you are already at $1k per PiB to grind with the M2 and then add a other $100 per PiB to download the file. So letâs say $1.1k per PiB. What the ROI with XCH at 15 dollars. Can someone do the math? Probably doesnât make sense unless you need an M2 Ultra for other stuff.
Assume the M2 uses 370 watts and you have average USA power costs.
