*** AMD "Zen" thread (inc AM4/APU discussion) ***

[harney]

Yes, I'm not dissing on AIOs, they perform just fine for the most part, but some people do have high expectations simply because they have liquid in them, which they believe is assured to offer a far superior cooling solution, when it factually does not. It's quite obvious many people buy them for this reason. The aesthetics argument is by far the strongest, and as mentioned, where high profile RAM or case clearance height is air cooler prohibitive.

On the faffing point though... I fitted a D15 recently and it was the easiest cooler I've ever fitted, bar none! The BeQuiet Dark Rock cooler is still a PITA though, so they aren't all so easy. Weight on the mobo isn't really an issue with modern boards, unless you're moving your PC around a lot. Noise levels can actually be higher with an AIO due to the pump noise... it's product specific and also the case can factor in, but a friend of mine has a Corsair AIO and regrets buying it because of the noise... he had a quieter system before with his BeQuiet Dark Rock Pro 3 cooler, and his temps are the same lol!

For Ryzen, no one NEEDS an AIO to achieve high performance from their CPU... that's the myth that needs to be busted here. There's a stronger argument for a custom loop if ultimate performance is desired (and you are happy to pay for it), but for a healthy overclock a top end air cooler will do the job perfectly fine, and then some!

Agree

Do people actually watch that muppet? most of his stuff makes me want to punch my screen.

Nope ^^^^ and ya me too, i find him pretty annoying.

"We’ve discovered that the backplates provided with some major motherboard brands could come with a screw that is too long. The screws reach their safety stop too soon, leaving the spring with too much headroom, and then the pressure of the sink on the CPU is inadequate."

Oh no...... its a ####### disaster ^^^^^^ run for your lives :O

omg this is as bad as no games using more than "1coregate"... I can see the headlines now "myscrewis2longgate"

Surely if the CPU heatsink contact is compromised, then it is an actual problem?

(I know that's not what the A stands for, it's a joke).

What he was actually saying throughout his campaign was 'Make AMD Great Again', it's just everyone misheard it as 'Make America Great Again'.

Funny that, just received Alphacool / Bequiet AM4 kit and have had email about pressure! will post up on Silent loop section

Over years i found out that only real stability test is.... Producing 2 hour long video in PowerDirector.
I could pass Prime Handbrake Intel burn test at maximum. And still crash after 2 hours of rendering .

Ryzen 1800x @4Ghz
AIDI64 Benchmark

Spoiler: AIDA64 Benchmark

Impressive memory performance latency seems high though.
Seems to be using Corsair MP500 NVMe PCIe M.2 and numbers look good or on par here against others.
http://ssd.userbenchmark.com/SpeedTest/213562/Force-MP500

Memory latency might seem high but everything else is pretty mind blowing.

Compared to my 4.2Ghz 5820k on 2400Mhz memory(it's 3000Mhz, worked at that for a while but stopped booting until mem speed was dropped ), the L2 cache of Zen literally doubles performance, L3 has 50% higher read, 3x the copy and marginally behind on write. L1 is a little slower on Zen. Read though... wow. My quad channel 2400Mhz is getting 46.9GB/s, Zen with 3200Mhz is beating it. Max theoretical numbers are once again popping up showing AMD smashing to pieces anything Intel has on efficiency. I don't have l2/l3 latency as trial version hides that, L1 read(so read might be great), also memory write/copy are hidden but there is no reason write will be monumentally higher than read, nor is it more important anyway.

At 2133Mhz Zen appears to have almost 100% bandwidth efficiency, Intel is at around 75% on Skylake/Broadwell, at higher memory speeds efficiency reduces for Zen it appears and Intel. Max theoretical on my system is 76.8GB/s and I'm getting 47GB/s, around 61% efficiency. 3200Mhz dual channel has max theoretical bandwidth of 51.2GB/s, so 47.7GB/s is still 93% efficiency.

Zen doesn't have a weak IMC< it has one of the best IMC's ever seen, with incredible bandwidth.

That bodes badly for Intel when it comes to APUs later this year. AMD has the HBM for super high margin products and Intel memory cube seems to be AWOL(and much more expensive and higher power, maybe it less use for mobile where Iris pro is aimed), but in more mainstream pricing AMD is looking like it will have 20-30% more memory bandwidth for their APUs at any given memory speed used. AMD APUs are going to absolutely destroy Intel on igpu performance.

Yes but its hardly a major Motherboard flaw, these are the same guys who made an issue out of the RX 480 apparently pulling too much power from the PICe when in his own reviews one or two nVidia cards were pulling more from the PCIe, he never even mentioned that and ignored it when that fact was pointed out to him.

Got webnote reply from OCUK, no Ryzen stock issues but:
"Motherboard supply is more limited and you may expect to wait longer for us to receive stock for sale".

Hopefully I didn't create a s*** storm but rather a heads up, when NDA lifts and AMD are gods gift to Intel fan boys etc etc etc etc
and its OCUK, guys do regular back jobs at distribution centers haha

@Gibbo can you please confirm if your screw is too long or not ?

Ryzen 1700 & 1700X benchmarks leaked:


GTA V DX11

Ryzen 7 1700 167fps
Ryzen 7 1700X 130fps
Core i7 7700K 190fps
Core i7 6800K 145fps


Hmmm very interesting peformance but I noticed something wrong with 1700X GTA V fps is lower than 1700, it probably another typo.

Look like 1800X OC will have no problem smash 7700K in every games benchmarks.

It's worth noting, the 1700x vs 6800k test used a 1080, the 1700 vs 7700k used a 1070, so that is why performance is different.

The real important thing is a stock 1700(which is unlocked) gets extremely close to a chip running around 1GHz faster than it, and by all accounts the 1700 clocks pretty well, it can close a lot of that gap. Sure the 7700k can also overclock but it overclocks a smaller percentage and after you hit a certain point gains will diminish significantly and the 7700k is almost there already.

The 1700 only seems to be running 3.2Ghz or so with multiple threads running, because it's a 65W chip. The 1700 65W chip is literally beating the 91W(iirc) 7700k in some of those games already, even if you overclock enough to be using 91W you'd be beating it in almost everything.

I will actually give you credit though, of all people you are saying a 1800x will not beat but smash a 7700k. I think a overclocked 1700 will beat the 7700k in most games now(newer releases, older stuff maybe not so much, but also not too relevant).

All i will say is i use handbrake and that pegs each thread/core at 100% usage.

Same here, along with Prime, very good stability test.

Decided to download and run the raw project through handbrake. It's a 400GB file with a source bit rate of 3540910kbps ( 3540.91 Mbs ), at 55 minutes 12 seconds in length.
The old Noctua is holding is own really well here.

I think it'll do any Ryzen owner rather well.
