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

[ubersonic]

I was under the impression that when utilizing all cores the Intel Chips do not boost?

Basically, unless an Intel chip with boost is having temperature issues it will boost, it's just the boost amount differs depending on the amount of cores in use.

I.E my 4930K has a base clock of 3.4GHz however I have never seen that because depending on the amount of cores in use it boosts to 3.6-3.9GHz.

Intel have spent years on efficiency, if AMD get anywhere near close it'll be very good

True.

Boost will be roughly 15% so wattage should scale accordingly.

At ~210w its going to be hotter than the sun

I've never streamed online.

Given how popular streaming is, I'm in two minds. I don't think there's an army of people running Intel hex and octo cores.

Dota 2 isn't exactly an intensive game.

A lot of the comparison for me depends on price, I expect the zen flagship to flatten an i7 6700k going maxed out, which would be great if that's the price point, but I just can't see it being the price point.

Apparently the newer updates to DOTA2 have made it more CPU intensive according to what I have read,but since I don't play it I can't really confirm it personally.

 

[DragonQ]

Seeing that they ran benches without boost (185w vs 190w) actual Zen wattage at the wall will be higher.

Nonethless this is going to be interesting.

It'll also be faster. What's your point?

True.

Boost will be roughly 15% so wattage should scale accordingly.

At ~210w its going to be hotter than the sun

Isn't that the entire system draw though? Anyone playing games with a separate GPU will be using way more than that with any CPU.

Also depends on the streaming settings, depending on how its set up you can throw a hell of a lot of CPU power at it.

That's true.

 

[SiDeards73]

That's true.

From reading reddit it seems a lot of people are impressed with the Handbrake demo and the DOTA streaming stuff, both seem to be something showing Ryzen is very impressive.

 

[Martini1991]

Like I say, I'm impressed with the handbrake.
Can't knock it at all about that. But it's the only solid I can take from it performance wise.

Price is very important. I'm not concerned about a lack of competition anymore though

+1 on the pricing comment, this will make or break the hold Intel has right now, if AMD are clever, price it close to the 6700k, they would effectively make the 6700k and the 6900k irrelevant, as why would you pay for the 6700k if for a few quid more your getting 6900k performance? and on that basis you would not pay Intels 6900k money for their product when AMD are offering the same at a much lower price point?

Anyhow it comes down to price, if they want market share they will undercut Intel by enough to make fence sitters and people about to purchase just choose them automatically (if performance is there ofc) and also those people thinking about upgrading and who are prone to impulse buys are more likely to spend the cash for the new shineys too.

 

[Seanspeed]

For me it was the DOTA comparison against 6900k and 6700k, it was clearly evident that the 6900k and the Ryzen both did not bat an eye at the game both being played and streamed at the same time, where as the 6700k played the game perfectly but struggled with the streaming at the same time. That to me was a good example of what the chips capable of.

To me, that was an example of them doing some funky nonsense because no way should a 6700k be struggling to that degree.

You seem to be assuming it'll even be as powerful as a 6700k in the first place.

Man, it's no wonder these presentations always include some ridiculous cherry picked tests that will fool gullible consumers.

 

[Boomstick777]

I fancy an all in one mini PC. If the APU's that come later can match say an RX460 in GPU performance an an i5 6500 level CPU I would be really happy with that. Low power decent PC. Might even eventually replace my high end PC. I do very little actual gaming these days. Although a few new decent games could change that lol.

 

[Martini1991]

There's no way that Zen 8 core won't smash an i7 6700k based on last night.

I'm of the opinion that if AMD have a stellar product they'll charge for it. But they've got a lot of ground to regain, so who knows.

 

[humbug]

I searched this thread and no one posted it.

https://www.pcper.com/reviews/Proce...Zen-CPU-Reveals-34-GHz-clock-and-more-details

PCPer recorded video on 8 December 2016 with much better quality footage to see full details zoomed in showed Handbrake performance and Blender performance with power consumption demo. With Blender app opened saw Ryzen consumed 93W and Intel 6900K consumed 106.5W, when it rendered Ryzen CPU workload saw Ryzen consumed 188.2W and Intel 6900K consumed 191.5W at full load.

That is so close, AMD with 'fractionally' more performance and 'fractionally' better efficiency, how many hours did they spend fine tuning Ryzen to get ahead of Intel? and the reaction once they push past the 6900K, jumping up and down screaming YES-YES-GET-IN *fist-pump*

Its looking good for AMD but a dose of caution here is probably a good idea.

 

[Martini1991]

Out of the people posting, sibeards probably been the most aligned to my own views. I find it hilarious he's been chosen as a gullible consumer lol

*sigh*

You cant help but give out the veiled insults can you?

If you look into the DOTA thing, its running on the latest version which apparently has hammered performance across the board for CPUs, coupled with the demand that streaming at the rates they were using, its why the 6700k was struggling to stream.

Its no secret either many streamers use a 2nd PC dedicated purely to streaming while they game on their main rig.

That DOTA demo was designed to show you that the 6900k and the RyZen can both do the gaming and Streaming on the same PC, in the newest version of DOTA, something that the 6700k is currently struggling with.

Last night answered almost nothing.

I wont call it a waste of time, because it was a taste teaser and we got the reveal of the full name and a few interesting tech bits, but in terms of actual performance, as far as I'm concerned, we're still very much in the dark.

All i saw was an AMD 8/16 chip beating an Intel 8/16 chip with similar clock speeds at both Handbrake and Blender while being quoted as less TDP.

Then i saw the same AMD chip handling multitasking at the same level of the top end Intel chip as it was both gaming and encoding / streaming without issue , while the mainstream Intel i7 was struggling to perform both.

The BF1 and Battlefront stuff was irrelevant mostly, the only thing they proved is AMD can run those games on their new CPU and GPU. Both of those demos are believe we more likely GPU Dependant rather than CPU.

The other good bit was the 3D Modelling stuff and how fast it was reacting to the guild moving it around etc, that was also really impressive and snappy.

Personally i think AMD have nailed the performance, i just hope they nail the price.

Its actually genius on Amd's part, they have everyone running blender and realising how rubbish their Intel cpu's are.

*Reality check* We know no more now than we did in August, something in me says that if it were to be truly competitive with the 6900k we'd have seen a few more benchmarks (and muted whoops from the audience) such as 3dmark, Realbench, cinebench. Personally i wont be drawing a conclusion until its in the hands of reviewers, been here too may time with Amd.

Even if they displayed a few more performance stuff, AMD will still pick things in their favour, so we'll still need to wait for reviewers to do the testing.

*Waits for zenmarks*

EDIT: Still, compared to Kabylake, I'm very tempted to pick Ryzen as my next system. My current i7 did well with Handbrake but moving onto h.265 has taken a fair hit in encode times .
