AMD - Zen chitchat

[DanceswithUnix]

Whats the point of mobile Ryzen 5 if Core i5 8250U laptops can be had cheaper and laptops with a Core i7 7700HQ and a GTX1050 can be had for similar money?? Its all a bit pointless then. There is no excuse when the AMD is a single chip solution and the competing ones use two to three chips and needs a more complex cooling solution too!!

Started a new job yesterday, spent most of the day trying to beat my Dell Precision laptop into some shape usable for coding. It is one of their range that can be delivered with Ubuntu on it, but I want Fedora so it was delivered with Windows so it has the license if ever needed. So I have to fight the storage controller settings, the switchable Intel/Quadro graphics and the Thunderbolt docking station.

I would have loved to have had a single AMD chip that just works. For now I have given up on multi-monitor support. I doubt the 7700HQ is life changingly faster than a mobile Ryzen at compiling code. I am starting to wonder if I should have gone for that monster Asus gaming laptop with the Ryzen 1600 and RX 580 in it. Lack of portability put me off on that one, the 1 hour battery life would probably never hurt me.

The problem is you also get a GTX1050 2GB thrown in on top of this. RR is a nice product,but pricing,availability and software support seems to be not all there currently.

You won't get a 1050 in a Precision laptop, this puppy has a Quadro in it. Utter waste of money as Optimus graphics switching means I still have to use the Intel graphics drivers.

I know Phoronix had problems with RR under Linux, but AMD's recent record on Linux drivers is pretty good so I'm sure it will get sorted soon. So far this laptop has been a real source of stress, I might get it sorted in the end but this is the established technology from the main players of Intel/Nvidia/Dell making a business laptop that is Ubuntu certified and I am still struggling, and I am sure this is as good as it is going to get.

Its probably even less of a chance of getting an AMD card in there!! But for the average consumer,almost all of the RR laptops seem to be sub-optimal in some way or another,and way too expensive,and under Windows AMD can't even support the laptop RR,and when people have forced desktop Vega 56/64 drivers on it and there was performance jumps,one has to go LOLWTFBBQ at it. I mean the latest RR laptop drivers are months out of date and you cannot even download them on their website(BR you could). By the time they sort it out,Intel would have also sorted out cheaper CFL SKUs.

It looks like HP has leaked 68 different configurations of AMD Ryzen powered Elitebooks:

Hopefully these will be better than the currently launched ones.

The nice bit about AMD graphics under Linux is that you can just install the latest OS and because everything is open source there is no hunting for drivers as the entire stack down to Vulkan is included. My home desktop has an R9 380 because that was the first chip that really got that support, and I really don't want to go back to downloaded drivers.

The dev target is an Altera based system, more so Intel downloads trying to get a dev kit that even installs.

Hmmm, 13.3", Ryzen 3 2300U, 256Gb SSD, 8GB of RAM. What do we reckon that'll cost, north of £700? *sigh*

EDIT: oh boy, just looked up existing HP Elitebook prices. If you buy direct from HP you can get the current gen 745 (G4, 14" FHD) with an A10 9800B, 8GB and a 256GB SSD for £790. Intel versions (Elitebook 800 series) start at over £1000, afaict. Given the tendency to price Ryzen laptops like their Intel counterparts, I think I know what to expect from the 700 G5 series...

A purported leak of some Zen+ scores:

Memory and cache latencies seem a decent amount lower!!

[Xlucine]

I've noticed something: the efficiency of the RR vega parts is unusually low.

Looking at historic AMD cards, they tend to score lower in time spy than similar performing nvidia GPUs - example one (570 behind the 1060 by ~8%, but equals it in games) and example two (V56 beaten by 1070ti by ~10%, and about equal in games). There's something odd about the RR scores, in this light - vega8 is well ahead of the 940MX (by 11%), which ought to correspond to a performance lead of ~20% (assuming the 3dmark:fps ratio stays constant), but the 940MX instead beats vega8. This is a major discrepancy - 20% more than an MX130 is getting close to MX150 performance, and so it looks to me like the outdated drivers are massively hobbling the RR APUs. Typical AMD launch!

Ryzen+ line-up leaked:

That is a big increase in clockspeeds!!

Edit!!

It could be a fake as the NDA date says 2017!!

[watercooled]

I wonder what's happened to the 2800(X)? Maybe they're waiting on yield ramp for higher clocks?

I'd think about putting money on it being fake. The slide looks a little too familiar. Plus why on earth would the slide detailing the Ryzen 5 2600 also have a Ryzen 5 1600 on it?! I'm also not buying a 105W TDP on the 2700X when all other AM4 processors have been max 95W. That'd be at serious risk of breaking backwards compatibility unless they'd over-specced the platform originally...

Also looking at some of the results they looked off - FO4 and Skyrim show big differences but use the same engine,and also the uncapped FPS difference between the 1800X and 2700X is only around 10% for FO4 and makes it equal to a 8700K(which is a load of Moose droppings),and then the uncapped Skyrim are 40% higher on the 8700K using the same engine.

If it was an AMD slide,then its downright deceitful:

An 1800X is NOT 10% slower than a 8700K at 1080p using a GTX1080 in FO4 especially if you look at minimums,unless they found an area which was mostly GPU limited.

apparently the am4 mobos can do 140w tdp

If that leak is to be believed the prices (or at least RRPs) seem a little marked up. Good speeds though, should be ok. Rumours GloFo CTO says Ryzen 3 @ 7nm will be 5ghz ish.

Another leak which apparently confirms the line-up:
