One is usually Intel GbE and one is usually either Aquanta 10GbE or Realtek 2.5GbE. People still remember when Realtek NICs were garbage and demand an Intel NIC on their high end motherboard, but other people want faster than 1 gig. So manufacturers put both to make both of those groups happy.

I think there's also an element of redundancy, with a side helping of ability to access two different networks at once (eg to use the PC as a router/firewall).

Besides link aggregation I’ve also seen a few people attach a NAS directly to the second port, essentially transforming it into DAS without internet access. It may not make much sense from a networking perspective but it’s a pretty common use case.

Yeah, having a dedicated pipe to your NAS means you can do one thing interactively on your desktop while a second thing is running in the background to another machine (assuming you have enough disk to support this). Plus it's the lowest possible latency since it's not going through a switch. The dedicated pipe may or may not be 10GbE, it's still useful with 1GbE, but direct connection is a great way to get started with 10GbE without dropping $250-500 on a switch. NICs are literally $25-50, so this is much cheaper unless you really really need to have your machine attached to the broader network via 10GbE. You can just plug the machines together and let everything else run on the normal gigabit network. Paul MaudDib fucked around with this message at 22:06 on Nov 25, 2019 |

If you're running network storage, it can be nice to have that run over a dedicated link so its not contending with front-end traffic

What’s the second one used for? it means when one of my ports just randomly stops working and falls back to 10mbit without even the ability to pull an IP address I can just plug the cable in to the other port and go on with my shitposting instead of having to actually go somewhere and buy a nic.

I’m surprised the idle power consumption of TR machines is quite high: 110W idle compared to the 50-55W of AM4 Ryzen. With a single thread load it climbs to 165W which is more than a 3700X system under full all core load. I’m guessing this is partly due to optimization and party due to overdimensioned VRMs running far from peak efficiency.

Have you verified the idle frequency/voltages? I had some problems getting power management to engage on my epyc servers at first and had to fuss with them.

The giant IO die might be another factor. X570's die could pull close to 10W just idle. This is a bigger die with a lot more connectivity, and also runs everything that would normally be on the PCH as well.

If you're buying 2k processors and complaining about fiber costs you're an idiot. The cost of a 100gbe switch and cabling is likely the same cost as one workstation and is 10x as fast as lovely copper.

It's pretty difficult not to be impressed with how AMD worked itself into this position. Then there is this interview with AMD's Forrest Norrodquote:When asked about what kind of performance gain Milan's CPU core microarchitecture, which is known as Zen 3, will deliver relative to the Zen 2 microarchitecture that Rome relies on in terms of instructions processed per CPU clock cycle (IPC), Norrod observed that -- unlike Zen 2, which was more of an evolution of the Zen microarchitecture that powers first-gen Epyc CPUs -- Zen 3 will be based on a completely new architecture.

The thing that impresses me the most is that Zen 3 is allegedly the first design that Jim Keller wasn't directly involved in. I was worried about AMD not being able to follow up after Zen and Zen 2 but these numbers sure don't make it sound like it.

If Zen3 is some juicy poo poo I might try and flip my 3600 and get the 4700 equivalent and just try and coast on that for 8 years like I did with my 2500k.

Budzilla posted:This is awesome. Hopefully these Zen 3 chips retain compatibilty with AM4 and x570 so I can buy a used 3950X for cheap when someone else wants to upgrade from that. AMD already promised compatibility until 2020 but with the recent X399 -> sTRX4 for threadripper I would not be surprised if they go backsies on that. There's very little reason to switch sockets until the DDR5 changeover (unless you want to add more pcie lanes). So I personally think that it'll remain AM4.

I suspect AM5 is going to last exactly one CPU release if AMD keeps increasing performance the way they do right now.  On a different note some local distributors are reporting 16:1 preorder/stock ratio for 3950X and Threadripper has similar problems. Reminds me of the 8700K launch.

Could I get help picking a motherboard? I'm planning to get an upper end Ryzen chip and RTX card for overclocking with a pair of AIO radiators. I'm focusing on x570 chipset in case I wanna drop in a future chip to coast a little longer. Sticking with ASUS I narrowed it down to: X570 Strix-E Pro WS Ace I'm leaning towards the WS Ace because the onboard fan is better (honestly I'm scared to re-live built in mobo fans), don't need wifi, and have my own audio card. Anything I might have missed?

So what's the release schedule of Zen 3 if we were to guess? 19Q2 for 3600+3700*, 19Q4 for 3900+3950? *3800 too if they do this weird binning tier again.

There's really not much in the way of overclocking headroom on Zen 2 processors, and the small boost you get is generally not worth the enormous increase in power consumption and heat generation (unless you're overclocking for the heck of it). If you're not overclocking, both boards are vastly over-engineered and a $200 board would be basically equivalent.

Yeah TSMC is charging ahead full speed, it can't last forever but they're progressing to new nodes faster than I thought possible at this point. Their 3nm fab is under construction now for a cool $20 billion.
