I'd like to see this data on Postgres scaling updated, with more info on the write scaling as well. (the chart appears to be for SELECT queries only)

Outside of some very exotic scenarios you are IOPS bound on writes and not CPU bound.

Is that still a problem with cheap NVMe drives that can do 500k IOPS?

In previous threads there was discussion about Intel processors, specifically Skylake (which is a desktop processor), being superior for server workloads involving vectorization. How will Naples fare on this front?

Desktop Skylake doesn't support AVX-512. Server Skylake will, when it ships. (The Xeon E3 v5 doesn't, because it's the same chip as desktop Skylake.)

This is what I have really been looking forward to. I theorycrafted a more ideal system for the genetics work a former employer was doing, but didn't get to build it until after I had left there. A quad 16 core opteron system for a total of 64 cores (for physics calculations in comsol). I think that there is more potential use for high actual core count servers than many people realize, so I can't wait to build one. (for my purposes these days is as an game server in a colo, one of my projects is a multiplayer UE4 game)

At the previous job where I built the 64-core system, I even emailed the AMD marketing department to see if we could do some PR campaign together, but I think it was too soon before the Naples drop, because I never got a response. Here's to hoping supermicro does a 4 cpu board for this... 124 cores would be amazing. (But I'll take 64 naples cores as long as it gets rid of the bugs and issues I found with the opterons).

Naples is based on Ryzen which, if you look at early benchmarks, is beating the competition on all fronts except gaming (suspectedly due to software optimisation and motherboard issues).

yes but four modules of ryzen to make this beastly naples chip isn't going to be clocked at the same frequencies. the top end intel chips have TDPs of 165W but 4 ryzen chips at 3.6ghz have a tdp of 65w a piece and you're not going to see a 260W server chip if you want to sell into the datacenter.

I can see a use case for it, as long as it delivers on performance. No one minds high TDP, as long as it offers a performance advantage. Hell, some servers have 4-8 Titans in them, and no one is complaining about their TDP. If a 260W CPU TDP is justified by the performance, no one will care.

Naples might not fare well, but AMD is betting on vector operations being offloaded to a GPU-like accelerator connected via Infinity Fabric.

Not a problem at all if you provision your server properly so you aren't IOPS bound, though there are plenty of databases which simply won't fit on NVMe drives, so in those cases, yes it could still be a problem.

Intel doesn't have SHA2 acceleration? ARMv8 has had it for like 2-3 years now... And AMD should dump SHA1 acceleration in the next generation.

>And AMD should dump SHA1 acceleration in the next generation. The cost to have that on silicon is probably close to zero. If you think SHA1 is just going to magically disappear because you want it to, well, you'll be in for a SHA1 sized surprise. Our grandkids will still have SHA1 acceleration. >ARMv8 has had it for like 2-3 years now... Because ARM cores don't remotely have the CPU heft an Intel x86/64 chip has, so…

Why should it be dropped ? Isn't it just a hash function ?

The Ryzen 7 1800X has a TDP of 95W and beats the 140W Intel i7-6900K by 4% in performance. They've made some huge jumps in power efficiency.

I don't know if AMD will make a new architecture or not, but I can't see why they wouldn't just release 32 Ryzen cores side-by-side and underclocked at the stock configuration.

If they have a much better performance/$ than Intel, which they likely will have, it sounds like a good opportunity for AWS to significantly undercut Microsoft and Google (which recently bragged about purchasing expensive Skylake-E chips).

There's opportunity cost to consider. Google has Skylake-E now which is not even available at retail yet.

Well, it also seems that Intel prioritized its customers. If I were Amazon or Microsoft (the rumors said Google and Facebook were the priority customers), I would get Naples just to spite Intel (it doesn't hurt that AMD's Naples likely offers better perf/$, too, though):

Out of curiosity, I thought that genetics was the domain of gpus?
