Still limited to a measly 208gb of RAM? That was pretty good back in the day, but now my desktop workstation has 128gb. AWS offers up to 488gb on their latest R4 instances, and 2tb on their X1 instances released a year ago.

No - I believe these will be up to 64core & 416GB

Nope. Bigger :).

I've been benchmarking these against Haswell and Broadwells. Despite being 300 MHz slower, we're getting between 5 and 45% faster benchmarks on linear algebra functions that we run a lot, even without doing much work to tailor to AVX512 instructions yet. The cache is also a whopping 56 MB.

I use 128 gb too but here we call it SSD

I try to consistently say "vCPUs", but yeah...

Given the marketing toward HPC tasks, shouldn't hyper-threading be disabled?

Disabling hyper-threading only makes sense if you're getting messed up by the OS's scheduler.

> "Heh, I know you don't want to talk about Azure, but perhaps others can share -- what's so bad about it?" This is what I will say: I'm working on a migration to it, so I'm not very experienced with it, but so far, it's been very painful compared to GCE or AWS, in which I've run production stacks. I'd rather not comment further, simply due to my relative new-ness to the service and the chance that it's just lack of…

Your GCE startup credits [1] or something else? Have you been in contact with our PMs about Pgsql? [1] https://cloud.google.com/developers/startups/

Yep, our GCE startup credits. We've only burned through about half of em (from the billing page, it looks like ~45k), and they expire in late march. So if we had an extra year to use 'em, that would be amazing.

When I last chatted with our Account Manager I mentioned Postgres, yeah. We're currently running our own on GCE, but it would be awesome to have it aaS, with replicas and automated backups that I don't have to keep an eye on all the time :).

Hahaha. Meanwhile I've been running 2 machines with Skylake and a combined 24 cores/48 threads, 256GB DDR4, 6x512G SSDs, unmetered 1Gbit/s public and 2,5Gbit/s internal for over half a year for a combined $150 total, in complete privacy and in full control of my hosts.. go dedicated, people.

The consumer Skylakes are not even in the same league as what we're announcing today. The easiest analogy is comparing a laptop to a beefy two-socket server. Disclosure: I work on Google Cloud (and of course want you to pay us to use Skylake)

> want you to pay us to use Skylake

I already use a nice E3 Skylake workstation at work, thank you very much. Could be an E5 or a big i7 with more cores (I just rechecked on ark and I guess it's still not available publicly for Skylake, but I also guess this can not held for very long...), but we want it to be close to our product target, which is an E3, so E3 it is.

For tons of practical purposes, lots of reasonable E5 are comparable to what you can get with the biggest i7 -- and during the last gen for tons of practical purposes gen to next gen comparable CPU have only progressed slightly. Of course there are workloads where you want to use the most insane CPU, or some CPU with new features / better perf in some niche workload, and so over, but when you start to have such advanced needs I doubt a little that OTS platform solutions are better for the majority of people with highly advanced needs...

But yeah, on the mass of people, some will remain interested by "your" solution. Meaning mainly Intel solution, given how you advertise Skylake soo much...

Vendor? Sounds too good to be true.

Depends on the workload. A compute bound vectorizable problem could be four times faster on Skylake.

Why 4 and not 2 (512/256)?

the masks on avx 512 can lead to more than a 2x improvement sometimes

I know security is not compliance, and I'm not here to compare the two, but Google goes to great lengths to protect security. [0] TL;DR: - Google's global SDN is ultra-secure, and Google carries your packets on its network rather than dumping them onto public web. Google's undersea cables are shark bite-proof! [1] - Google Data Centers are mostly homogeneous and rely on Google-build hardware rather than vendors. This…

I can't find "ultra-secure" in any of our security certification docs. Is that better or worse than "super-duper secure"? For security, I don't care whether my traffic as routed over a private network or public web as long as the data is encrypted, because a "private network" is only as private as thousands of miles of fiber and every single network facility it traverses can be. Which means 'not very'. Does Google bu…

Ha.ha. Did I mention I'm not in marketing? I do appreciate your passion!

On your first point. There is a very strong risk of inadvertent misconfiguration or your employees not following best practices.. Or even poor documentation. Google cloud by default gives you a global secure vpc that never traverses public internet, so there's less risk because the baseline of security is high. Sure, you can run VPN tunnels between data centers. Point is, with Google cloud you don't need to.

On the latter point, of course you cannot eradicate every vendor, especially within the obvious context of this specific Intel announcement... But, again, not having three dozen flavors of configs and four network router vendors does make a difference. I would encourage you to read the paper I linked to above (discussed this topic in great detail), and also perhaps [0].

Also security folks at Google, who are much more qualified to discuss this topic than I am, frequently post on hn. [1]

I'd rather wait for Ryzen. You won't know which Skylake processor you're getting - the gimped one or the non-gimped one. AMD tends to keep their features consistent across the line.

What do you mean by "gimped?" As in the consumer chips without AVX512 vs. the server chips with AVX512?

Yea, meanwhile AMD tends to keep the features across both desktop and server lines of CPU the same.

And the pre-release Skylake server procs seems to be gimped as it's missing a few features versus the actual official release Skylake server procs.

damn. out of curiosity, what do u use that much ram for?

I honestly can't think of any viable purpose for that much RAM unless there's a huge amount of waste happening
