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

[eddyr]

Is the R5-1400X going to be a single-thread performance champ? Presumably it's the top-binned single "CCX" (4-core module) SKU, and it has XFR.

R5-1500 and above are presumably dual "CCX", sometimes with 2 cores disabled.

The 6c chips have double the L3 cache serving only 50% more cores (if the chart is to be believed).

Its not. i'm relatively new here but you Silent Scone and that drunken bloke are so afraid of being wrong over something that no one is sure about .you have to argue like ****ing kids for hours.. when you're not on the thread its informative and interesting... away from that its tedious you all need to get a grip...

Yes,and yet unlike YOU I at least bother to post many of the new leaks and have been doing it many threads since 2009.

This is not your forum,so if you don't like then you can clear off YOURSELF instead of ordering other people to - arrogant git.

Edit!!

I also love how you are not quick to attack none of your stupid mates going on about stupid maximum overclocks,etc and yet you are such a troll yourself you can't even have the balls to try and say if my argument is valid or not.

I suspect it because looking at your setup ,YOU want to upgrade to a Core i7 on your current setup,so me going on about things like the IPC(and extra clockspeed) on a KL/SKL setup means you are annoyed with that comment I made.

 

[Perfect_Chaos]

Are all the Zen CPU's going to be for the same socket? If so that would be good, 3+ years of upgrades on the same motherboard.

See above

look how annoyed you are.. get a grip you div listening to you three ***** irrespective of what kit i have or the level of my knowledge you bring this place down.. grow up even the mods are pulling you.

Its looking like it, although they might do what they did with AM3 and bring out a AM4+ after a while which improved power delivery and some other stuff.

You used to be able to use AM3 CPU's in some AM3+ boards with a bios flash.

Better prices than I thought............... damn it I just moved away from a desktop, but could do with 8/16 cpu.

What's the chances of these 8/16 cpu's being in laptops ?

 

[Panos]

If correct somewhere is an announcement from AMD that AM4 is the socket for all Ryzen. With or without IGP etc for years to come.

AMD doesn't change socket every year

 

[CAT-THE-FIFTH]

funny how the goal posts move over time huh? lol.

AMD know what they have to do price wise. I can see ryzen being very competitive. If the IPC is right up at broadwell and manage to get 4.2 - 4.5Ghz with watercooling im jumping in. 8core16 thread will keep me tied over for a long time. Not to mention AMD seem to stick with the same socket unlike intel where u need a new board all the time.

Yep,and you can see how much annoyance when its brought up,it will make little of no difference in realworld performance,even if Intel is a bit ahead on ST.

Having said I think I noticed its not the AMD sockets but the CPUs themselves which have longevity.

AMD has a history of maintaining CPUs in different sockets - for instance an AM3 CPU would work in AM2,AM3 and AM3+ sockets. An FM2 CPU in FM2 and FM2+ sockets.

This is what is annoying with Intel changing sockets - my current IB Core i7 was on an H67 mini-ITX motherboard which died just outside warranty and by that time only one mini-ITX motherboard with SATA3.0 was left for sale in the UK by then at under £120. It was an ASRock B75,which was technically a slight downgrade!

Are all the Zen CPU's going to be for the same socket? If so that would be good, 3+ years of upgrades on the same motherboard.

Lisa Su said the APUs are coming to mobile first,but looking at the outputs,I suspect the APUs will be supported,so here is hoping the platform is long lived.

Better prices than I thought............... damn it I just moved away from a desktop, but could do with 8/16 cpu.

Ryzen CPU is a two CCX design. I suspect the APU will have a single CCX replaced with a GPU module,if I am reading into it right.

So I think 4C/8T,but it depends if one of the big laptop OEMs decides to be brave and make a barebones desktop replacement with AM4. IIRC,they have done such systems with Intel:

So it boils down to how well AMD does I suppose.

if its faster it might.remember the 5ghz speed is gunna be close in 99 percent or faster than any of the amd stuff in games and many day to day uses.

people need to just inhale a little and breathe in fresh air and not helium

Bear with me, because I had a little difficulty understanding exactly what you may have meant.

Assuming that the price for the 6c/12t R5 1600X is correct at £240-270ish, and that the base and turbo clock speeds of 3.3GHz to 3.7GHz are correct, and not taking into account OC ability, then comparing it to say the £300 7700 non-K. Even if the IPC means a 10-15% loss over the Intel, at 3.6 - 4.2GHz, then you lose an effective 500-600MHz per core of performance on the AMD chip, totaling around 2.4GHz of lost performance if you want to make it simple. Then factor in the other two cores, which add a minimum of 3.3GHz per core, less the IPC loss so you are still up on performance by a whole core + a bit and it costs less.

As for the helium part, no idea what you mean but rewind the clock back to the pre-launch of the Opteron/AMD64 CPU's - that was crazy.

Well that's no help.

So we still don't know price or performance and yet people are still arguing

Relative performance is still somewhat of a mystery, agreed.

You don't even need to go that far on Eurogamer:

http://www.eurogamer.net/articles/digitalfoundry-2017-intel-kaby-lake-core-i7-7700k-review

Look at the numbers,they are running a Titan X at 1080P,like many reviews tend to,ie, try to make it less of a GPU limited situation like you get with most games.



Assassin's Creed Unity and The Division,show hardly any difference going from an overclocked IB Core i7 to the latest Core i5 or Core i7.

In Ashes of the Singularity,Crysis 3,Rise of the Tomb Raider and The Witcher 3,do you notice how much you gain from 4 threads to 8 threads??

Even a lower clocked 6C/12T CPU with lower IPC,is not going to really lose in those games.

Then you get Far Cry Primal which does seem to favour only 4 cores at most.

It really only needs AMD to get around Haswell level IPC for them to be close enough.

 

[CAT-THE-FIFTH]

From what I gather its the performance in 3DMark of a 3.4GHZ baseclock SKU overclocked to 4GHZ. OTH,3DMark does scale well with more cores,so is probably not a good benchmark.

Edit!!

Actually reading his comment again - someone said it must be 4GHZ boost,and the editor says 4GHZ base??

 

[muon]

Are we really going down the route which famously led to [H]ardocp claiming Conroe was no better than Athlon 64 X2 chips?

gaming benchmark being used is mainly console games

Sadly most big games are multi-platform,and this is probably why The Witcher 3 was somewhat downgraded from what we expected!

Interestingly looking at some of the really big PC exclusive games like LOL,DOTA2,etc I think even our "old" CPUs are more than enough!!

OFC,we could say ARK was a PC exclusive at the beginning but the less said about the optimisation in that game,the better!!

Just had a peek - is that set of benchmarks the same one that has been floating around for the last 5 days or so - the reference to poor memory, the low frequency and the lack of boost makes me think so.

The gif hyping the overclock performance is funny - it would be awesome if it hinted at what actual speed got the reaction though. -edit- and all the twitter comments basically say the same thing! Would be fun to place bets on what the best stable overclock reviewers can get on air and water.

If you think about CES there was a massive number of waterloops on display - I am going to put it out there that I think the 1800x can sustain 4.4ghz+ on water, based on absolutely nothing.

-edit 2-
If the APU has 4c8t and a decent chunk of Vega in it that could be a really exciting chip. It is just a shame that they don't have a bespoke slot for graphics memory on APU motherboards. If they could somehow create a socket with even single channel DDR4 for the CPU and HBM2 on the graphics you would have a system that could potentially handle VR from an APU. As it is I assume the DDR4 will be a major bottleneck for the Ryzen APU in graphics performance.

Yeah,it would be nice to get some indication of the clockspeed too.
