AMD - Zen chitchat

X470 is AMD while Z490 is Intel?

You'd think so, but the source claims Z490 from AMD and a Z390 from intel

Exactly... just when you think things are confusing enough:


Could just be a typo or error. If it was X490, it would make some sense.

Definatly a processor that ill be keeping a close eye on! thanks for the informaton xD

HP's business line Ryzen laptops are going to launch soon:
https://www.anandtech.com/show/12731...with-ryzen-pro
https://www.notebookcheck.net/HP-Eli....303074.0.html
The most interesting bit is surely that the EliteBooks are the first AMD laptops with a ThunderBolt port, in this case ThunderBolt 3.

Compared to ThinkPads or Latitudes the hinges don't seem to open as far, and unlike the older 800 Elitebook, the 700 series don't seem to have a maintenance hatch.

If they had been 3 or 4 months earlier, I would have gone with AMD for sure... instead I have an 17-8550u thinkpad... still good though.

My thinkpad can open 180 degrees, until it's flat - but does anyone have a use case for this? Without a hinge that can open almost 360 degrees to pretend to be a tablet, I can't see any advantage in a laptop that opens further than you'd need it open while using it on your lap

If it's touch screen then it's nice to lay it flat for collaborative work around a table.

I don't know about anyone, but when I had an EliteBook 840 I remember trying to use the laptop propped up with some cushions on a bed with me knees bent and couldn't tilt the screen back to get a proper angle. Not helped by that 840 having a TN screen but while it's not a common position I certainly use it occasionally. No problem with my current ThinkPad T540p although since I upgraded it to IPS having the correct angle is not as important.

No specific use case that I can think of in terms of actual usability, but in terms of durability it means that
1. The hinge is very unlikely to bounce off its "stopper" often
2. If someone knocks the screen whilst its on a desk/lap, it will just open more instead of falling over/stressing the hinge.

I used to have a combination docking station and laptop stand, and being able to open the laptop to almost 180 degrees meant I could increase the vertical height so the screen was in the right ergonomic position for my stupidly long back (and, as a result, the top lined up with my normal monitor too).

According to a Phoronix story, Sony is doing some work with Zen optimizations for the LLVM compiler:
https://www.phoronix.com/scan.php?pa...n-Improvements
"One of Sony's compiler experts has taken to working on some tuning for the AMD Ryzen "znver1" microarchitecture support within the LLVM compiler stack. This begs the question why Sony is working on Ryzen improvements if not for a future product.

Sony's Simon Pilgrim has been recently investing time in the "znver1" AMD first-generation Zen CPU support within LLVM. Simon has been a programmer for Sony for the past decade. His LinkedIn reveals that indeed at Sony he's working on compiler tooling for the PlayStation devices"

So either Sony will use Zen on their next playstation, or this is one heck of a diversion

[Xlucine]

With Zen CCX's available in the AMD catalogue, jaguar cores in the next playstation would be quite an odd choice

I got the impression that cat cores are no longer in development as AMD aren't in the market for tiny cores (which at 7nm I guess a Jaguar like core would be). It just generally made sense.

Does raise the question, did Sony make optimiser enhancements for the PS4 during it's development?
