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

If they can do a 6 core at around £250 then I'll be tempted.

I would expect that, ~£250 is what Intel were charging for their flagship quad core over 8 years ago (back when four cores were the limit) and if AMD is serious and sensible (I.E no FX-9590 lolpricing) then the chip/price you're after sounds realistic.
 
IF the ipc is close to a 6700k and IF its overall speed is close to a 6900k and IF it's priced at £500 for a 8/16 and £150 for a 4/8 then almost every self build system should be an AMD system. Until we have them to buy and bench this all sounds too good to be true. But what IF...! we can only hope but lets keep our feet on the ground for now.

they need to match or preferably beat 6700k price and performance or people will stick with intel. hoping for 8 core at 6700k price.

Pricing to OEM's will be the key factor to success and of course decent marketing for the CPU. I suspect many manufacturers will love to have reason to dump Intel inside for the right price / performance ratio.

My reasons for ryzen (that sounds better than I thought :D) are;

Dropping AM3(+), the chipset is showing its age and has a poor choice of format. 900 series almost exclusively full ATX and mATX only on 700 series.

New possibilities for OC. Say what you like about Piledriver, I had hours of fun getting the thing maxed and the variables were huge.

Less power (at the wall) probably a fairly minor consideration when most here have a big graphics card and PSU. But leads to saner cooling.
 
Not wishing to stir the pot up again but what does blender test, IPC or multithreading? I ran the test last night with the same settings and it took 1m 26 secs on my 4670k. What I want is much more IPC as the game I play the most is for the most part, single threaded and my 4670k is holding my 1070 back.
 
Surprising how big the gap is in that blender benchmark between 4 and 6-core Intels and this 8-core Zen.

As I posted in the other thread Raelgun's 5820K is only slightly slower than one would expect based on the cores*speed numbers.

But then humbug's 4690K is way slower in comparison - it's got 32% higher clock speed but half the number of cores (i.e. the Zen has a 51% advantage overall on paper) but then the Zen gets 140% better performance, a huge gap.

Maybe SMT has a huge impact in this benchmark. It's not normally so large in Blender though.
 
I think some people are getting a little carried away with the pricing, I think best we'll see is the 8 core around the price of the 6800k/6850K maybe $500-$600, then a 6 core around the price of the 6700K $350ish and maybe a 4 core close to the 6600k $250ish

which will translate almost 1 to 1 into pounds with the exchange and taxes and overheads as they currently stand.

Its still undercutting Intel enough to shake things up, but people need to not get carried away, or it will just be more disappointment.

Even these prices might end up being wishful thinking. For all we know AMDs plan might be to undercut Intel by 10% which won't really affect the market much at all.
 
it does seem to sit if accurate around a 5820k ocd 6800 ocd.in blender but as already pointed out by numerous people you dont know what they used. blender build.

also with how they did the comparison of the 6700k and streaming dota it wouldnt suprise me if some of that isnt going off with the blender thing.

then again. $500 dollars for the cpu its realistic pricing really.thats going to be atleast £500 here after brexit gouging and whatever excuses is made for it being dearer :D

thing is if its slower in everything else like games and such.it could be decent it could be just AMD as cpu usual.interesting times.

awaits actual benchmarks by many.before boarding the AMD cpu super train :p
 
So it turns out that AMD 'accidently' uploaded the wrong Blender demo file so that when people ran it on their current systems they were miles off Zen in terms of performance. Cheap tricks or what. I wonder if they accidently used the wrong file on the 6900K system during the presentation?

Performance is still up in the air for me, too much smoke and mirrors marketing BS so far.

it was set to 200 and not 150 samples as they used. That's all. Not smoke and mirrors is it?

Ive repeated this to you a few times, they used the 2.78a X64 build from Blenders own website...

Blender and Handbrake test different uses of the CPU, one is Integer based and the other is Floating point based stress, the RyZen beat the 6900k in both of these tests, FP is basically what gaming uses...

I really dont understand how people find these things hard to believe and think there is some conspiracy or dodgey dealings going on.

AMD presented their chip, running at stock, put it up against the equivalent 8/16 Intel chip, they showed it beating that chip in Both Integer and FP based tests, they showed it outclassing a 6700k and keeping up with a 6900k while simultaneously playing a game and streaming on the same PC.

I just dont know what else they need to show people to convince them that the chip is a great chip. They even showed it running games, yes those were GPU limited scenarios, but it atleast showed the CPU was not holding them back.

basically any company will use what they can to sell their product highlight what is best.its not just amd nvidia intel do so aswell.

in the benchmarks like they did for streaming dota for eg with the 6700k.like i seen with numerous amd benchmarks and mantle for eg.

if your product is strong and fast as you say show the benchmarks that matter !

why no battlefield 1 benchmarks ? the most optimized cpu benchmark that utilizes cpu cores currently ? :confused: you want to show cpu power for a large sector of the market but choose to not do that benchmark :confused:

so while i think it will be a decent product why not simply do all the normal benchmarks we see like cinebench like bf1 like you know everyday or ususal products ? you know why just like i do.

as for blender benchmark as clouds of doubt have sprung up already over build settings used and such you do have to ask is it a light stripped version or something tinkered with.you really dont know.as said by many wait for real every day benchmarks before jumping on the amd blender train.
