AMD - Zen chitchat

[Biscuit]

So is that EPYC as in epic do you reckon?

Well after reading other tech news it would appear it is. A bit cheesy but it could be worse.

My word that's abysmal. I hope this turns out to be a misunderstanding of some sort, that's ridiculous naming for the server side of the business.

Seems Vega is confirmed to use InfinityFabric although I'd still expect Navi to be better at that especially if Zen2 brings higher speed / better latency to IF.

6) Many argue that vega is just a refined polaris gpu, how would you respond to this ?

My software team wishes this was true

Vega is both a new GPU architecture and also completely new SOC architecture. It's our first InfinityFabric GPU as well

Guess we now have three reasons for Vega being late:

1. HBM2 shortage (but 2x4GB stacks shouldn't be that rare while 2x8GB is)
2. waiting for Zen to launch
3. working on drivers

Well, epic names are not new for server parts as Epyc comes just as EPIC is going with Intel announcing the last Itanium.

Looks like we might have a partial picture of one of the RX Vega cards:

If you look at the backplate and the position it looks nothing like that of any of the Fury based single or dual GPU cards. The closest is the Fury Nano but that has a different top bit.

A mate bought an MSI Tomahawk B350 motherboard with a Ryzen 5 1600 and it worked perfectly fine out of the box. They got some Adata XPG Z1 2933MHZ DIMMs since they were not too expensive and were certified by AMD - out of the box they got 2666MHZ,so looking to see if with some newer updates and tweaks they can get closer to 2933MHZ.

Another mate did a build with a Ryzen 5 1400 and this motherboard:

On the stock cooler and stock voltages it could hit 3.7GHZ although the only issue is the lack of VRM cooling so they dialed it back to stock clockspeeds,but the motherboard is well under £70. They also had a 2400MHZ set of Kingston Hyper X DDR4 which seemed to run at 2666MHZ fine.

That would be me, build was for someone else so I had to put it back to stock, but I had a quick play. By "it could hit 3.7GHz at stock volts" I mean I set it to 3.7 and vcore to 1.2v, which is what auto seemed to be setting it to at stock, booted it and ran P95 for 10 mins. It may well have shown instability with longer P95, or it may have gone faster at that voltage. I didn't want to push too hard or test for too long - the board has no VRM cooling, it only supports 65w chips and it wasn't mine. The Asrock AB350M (non-HDV) however does support 95 chips and has a VRM heatsink, so if you want to OC on a budget that could be a good option (£66.60 on CCL atm).

It did occur to me a couple of weeks ago that - OC capacity dependant - an R5 1400 + B350 mobo + 2933MHz RAM + RX 570 would make one hell of a base for a 1080p gaming rig. Interesting to have some real world OC figures and advice!

Of course, I have no real use for a proper gaming rig at the minute,. but it's always interesting ti window shop..

The R5 1600 is still the price-performance sweet spot though:

Its actually under £200 now - in some games the differences are massive:

That area is not too CPU intensive,but if you look at the R5 1400 it seems to get have more frequent dips.

That's pretty similar to what I've just built. I was asked to build a gaming pc for approx £500 (base unit hardware only). Ended up with R5 1400, B350 mobo, 8G 2400 CL15 ram (which seemed fine at 2666 CL16, but I put it back to stock), Sapphire RX570 Pulse ITX, 1TB HDD, Be Quiet 400W PSU, case and AC WiFi adapter for £550.

The Ryzen alternative was a G4560 and either going up to an RX580 8GB or including a 240GB SSD. Now that the G4560 has HT I don't think there's a CPU worth buying between the G4560 and R5 1400 currently.

Thank god you didn't get that crappy XFX XT 430W and I found that BQ unit!! I did some more research and it had worse caps than CrapXon.

But I do still think you should have got one of those A320 motherboards with the heatsinked VRMs,as they seem to support 95W CPUs out of the box.

Expensive for a B350 motherboard but look at the VRM section:

https://www.techpowerup.com/233673/a...ng-motherboard

I wonder if it will be a "cheaper" alternative to an X370 one.

[scaryjim]

... look at the VRM section ...

Am I seeing 8 phases there...?!

It's £117 on OCUK. MSI also have a B350 board with many phases.

I'm struggling to see the point though when you could get this for similar money: https://www.cclonline.com/product/23...board/MBD2177/

The X370 is on offer - its £130+ elsewhere,so as long as you can get it for £120ish it seems a better choice,but if it reverts to the £130+ normal price,it will still make the Gigabyte the cheapest AM4 motherboard,with decent phases,6 SATA,lots of connections,etc. Its not "cheap" for a 970 equivalent even if we add a few quid for the exchange rates,but I do feel the Ryzen motherboards are a tad pricier than I expected.

Wonder if X399 Threadripper would be possible on an mATX board?
Certainly ASRock do an LGA-2011v3 mITX , and skinflint list seven LGA-2011v3 mATX boards. That mITX is a bit strange as it's two DIMMs only despite LGA-2011v3 being quad channel.

So far on Comdex, I've only seen mention of four X399 boards
ASRock X399 Taichi and X399 Professional Gaming (https://www.computerbase.de/2017-05/...-threadripper/)
Asus Zenith Extremem X399 (https://www.computerbase.de/2017-05/...-threadripper/)
