I think Naples is a very exciting development, because: - 1S/2S is obviously where the pie is. Few servers are 4S. - 8 DDR4 channels per socket is twice the memory bandwidth of 2011, and still more than LGA-36712312whateverthenumberwas - First x86 server platform with SHA1/2 acceleration - 128 PCIe lanes in a 1S system is unprecedented All in all Naples seems like a very interesting platform for throughput-intensive…

Intel hass had SHA1/2 acceleration for YEARS via the AES-NI instruction set.

How well does, say, Postgres scale on such hardware? Is anything more that 8 cores overkill or can we assume good linear increases in queries per second...

My guess is the 1 socket options scales great. 2 sockets are are less than ideal, and you will not double the 1 socket performance.

Nice. This is the more interesting market for AMD rather than the gaming market in my opinion. 128 PCIe lanes and up to 4TB of ram will be awesome.

Gaming? More like consumer market, Ryzen 7 is definitely not suited for gamers, advertising it as such was IMO mistake. Nevertheless Naples can be big innovation in server segment.

Also what with ECC? Ryzen can support it or not?

Let's hope this isn't niagra again: it needs to have decent clock speeds as IPC is still worth something today. But yes, I totally agree, this is an exciting chip.

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).

haha nope. This is not a part of AES-NI.

The only processors so far with these extensions are low power Goldmont chips.

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)

It's just as suited for gaming as it is for anything else. The problem is everyone expected all games to run buttery smooth on day one with no hiccups. Ryzen specific game engine optimisations are coming according to AMD, as well as a Windows 10 scheduler patch. There are also other issues on the motherboard/BIOS side which manufacturers are working on.

Not being the top single-threaded performer which is required to push many many hundreds of frames per second != "not suited for gamers". Games in general are more likely to be GPU-bound!! Intel's quad cores are only really required for the pro Counter-Strike players who want 600fps at 1080p just to get the absolute latest frame.

BTW they advertised it as good for gaming + streaming (h264 CPU encoding at the same time on the same machine). And "content creation", which pretty much always means video editing.

IIRC Ryzen supports unbuffered ECC if the mainboard supports it.

The other change is now a single select can use multiple cores, so you could see how that scaled to 32, 64, 128 cores...
