I don't know anything about Colo Crossing (are they a reseller?) but I would bet their $60 per month 4-core Intel Xeons would outperform a $1,000 per month "compute optimized" EC2 server.
For $1000 per month you can get a c8g.12xlarge (assuming you use some kind of savings plan).[0] That's 48 cores, 96 GB of RAM and 22.5+ Gbps networking. Of course you still need to pay for storage, egress etc., but you seem to be exaggerating a bit....they do offer a 44 core Broadwell/128 GB RAM option for $229 per month, so AWS is more like a 4x markup[1]....the C8g would likely be much faster at single threaded tasks though[2][3]
Wouldn't c8g.12xlarge with 500g storage (only EBS is possible), plus 1gbps from/to the internet is 5,700 USD per month, that's some discount you have.
If I try to match the actual machine. 16G ram. A rough estimate is that their Xeon E3-1240 would be ~2 AWS vCPU. So an r6g.large is the instance that would roughly match this one. Add 500G disk + 1 Gbps to/from the internet and ... monthly cost 3,700 USD.
Without any disk and without any data transfer (which would be unusable) it's still ~80USD. Maybe you could create a bootable image that calculates primes.
These are still not the same thing, I get it, but ... it's safe to say you cannot get anything remotely comparable on AWS. You can only get a different thing for way more money.
That's not dedicated 48 cores, it's 48 "vCPUs". There are probably 1,000 other EC2 instances running on those cores stealing all the CPU cycles. You might get 4 cores of actual compute throughput. Which is what I was saying
That's not how it works, sorry. (Unless you use burstable instances, like T4g) You can run them at 100% as long as you like, and it has the same performance (minus a small virtualization overhead).
Are you telling me that my virtualized EC2 server is the only thing running on the physical hardware/CPU? There are no other virtualized EC2 servers sharing time on that hardware/CPU?
If you are talking about regular EC2 (not T series, or Lambda, or Fargate etc.) you get the same performance (within say 5%) of the underlying hardware. If you're using a core, it's not shared with another user. The pricing validates this...the "metal" version of a server on AWS is the same price as the full regular EC2 version.
In fact, you can even get a small discount with the -flex series, if you're willing to compromise slightly. (Small discount for 100% of performance 95% of the time).
This seems pretty wild to me. Are you saying that I can submit instructions to the CPU and they will not be interleaved and the registers will not be swapped-out with instructions from other EC2 virtual server applications running on the same physical machine?
