An AX161 at Hetzner with 32 physical cores (EPYC 7502P, 64 threads) costs ~$130 per month, that works out to $0.17/hr ($0.0053 per core per hour).

That comes with a setup fee of 40$ though.

Annual purchases don't have setup fees as far as a I know, but it's probably just a way to charge more if you're only using it for a short while

I also want cheapest compute for software video encoding, ARM or x86 is fine. can someone give suggestions? I am currently using oracle cloud

Specifically for Video encoding I'd look into benchmarks about what certain ARM architectures can do. Not all encoders can correctly utilize them and they may end up very slow.

Yeah.

That being said, Hetzner sometimes has weeks where there's no setup fee on some of their servers. Doesn't seem to be the case for these ones at the moment though.

Earlier quoted context omitted.

Oh, good point. Yeah, that'd need to double the ram if they're going to use 4GB ram per SMT core. :) Doing that moves the cost up to €165.80 for 64 SMT cores with 256GB ram for a full month. (Note - I've updated those prices as I previously forgot to set the region to "US" for the Hetzner pricing thing) -- Lets see if my math is working today. ;) €165.80 / 64 cores = 2.5906 per core, per month Using 720 hours a month…

That is comparing an SMT core to an actual core. The c5.18xlarge is 36/72 cores/vcpus. Still cheaper, yes. Though I don't know how much you lose in scheduling trying to keep it fully utilized 24/7 versus the spot pricing.

Ok, I must be confused?

You pointed out initially that it's 128GB ram for (only) 32 real cores. That's still 4GB ram per core.

What am I misunderstanding? :)

That being said, if they're just doing bursty work and won't use servers for long stretches then it's probably not the right choice.

Where are your videos? Encoding is a more complicated problem in that the source and destination would impact things. Bandwidth transfer can cost more than the compute on some clouds (and impact speeds). If it's on S3 it might still be best to use AWS EC2 in the same region. Oracle is definitely a good choice with 10TB free tier. Hetzner cloud likely has cheaper compute than Oracle. Upcloud has the fastest CPU.

I have videos on Google drive. For hetzner can you tell which one to buy? They have many offerings- dedicated, cloud etc.

A little off topic. I was looking for a cheap cpu render farm for the project and ended up buying some chinese amd mini pcs. After a few months, I sold them at a retail price in just 3 days, there was a huge demand for them. I was very surprised by the power and almost silent operation compared to the insanely expensive and noisy servers that were used recently.

Why does one have to ask HN for this? It looks to me like the market could be more transparent here.

the price confusion/obscurity facilitates higher prices, none of the players on the sell side would benefit from lower margins, so they all do the same

Yeah, but that would stimulate the existence of comparison websites.

If you’re using aws spot pay careful attention to the region. In many aws regions spot prices have skyrocketed and offer less discount over on demand. Other regions have very cheap spot prices still. Also consider looking at equivalent instances like the c5d family.
