>QUANTUM LEAP
I hate this.
i3 > Zen
Who gives a shit, if it performs like an i5 from last year.
That would make it 5% behind Intel's current stuff. Huge jump from Bulldozer.
>quantum leap
>slower than old intels
lmao
Me, because I could get an affordable last year i5 with 8c/16t
So what? I'd be happy to spend less on a reasonable processor so I can drop some more cash on a new graphics card.
I am now gay.
> AMD says Zen CPU will outperform Intel Broadwell-E, delays release to 2017
arstechnica.com
I'd probably even buy it if it performed the same as Sandy Bridge, just to spite Intel and their disgusting practices.
For real. Unless I fire up a video to encode I rarely use 15% of my 4770k.
CPUs are rarely a bottleneck.
AMD is back, believe the hype.
It's ok, be becamea bimbo girl now.
You're just half gay.
muh dik
I do emulation so I need intel.
>2017
REEEEE, I WANT TO UPGRADE NOW. IM SICK OF MY 2500K
going to love the wait meme on this one
>unlabeled axis
literally what
It's wait time.
...
>All those retards in this thread think Summit Ridge will be cheaper than Intel's i7.
Loving every laugh. Expect 8c/16t starting at $300 and going up.
Problem is 14nm LPP, they won't clock as high as Intel. Maybe Zen+ will use 14nm (or 10nm) SOI FINFET
Stop regurgitating this stupidity. The Stilt is a smart guy, but he understands literally nothing about process.
Samsung's 14nm clocks higher than 28nm HPP, and we have 28nm HPP chips on the market right now with 3.8ghz turbos and a 3.5ghz base clock.
Global Foundries will not offer a 10nm process either as its only a half node from 14nm. They will move to IBM's 7nm process after 14nm for high performance chips.
>It only has 4 physical cores
>higher core count at same price
>priced like an i3 from current year
>unlocked multiplier on every chip always
>hardware virt on every chip always
>no IME (PSP won't be on high end desktop chips)
>way way longer motherboard lifespan
I'll trade a nominal decrease in power for all of the above. Any time. You don't belong on Sup Forums if you wouldn't.
If they can hit 4 GHz I'll be content
>>no IME (PSP won't be on high end desktop chips)
[citation needed]
>Zen logo
>that smear
Found AMD's inspiration
With a stock turbo of 3.2ghz on an ES inside of a 95w TDP thats a virtual guarantee.
>Early 2017
Fuck, I want to do a zen build for my next system, but there have been so many delays.
What the fuck, I hate intel now.
it officially announced to come out in Q4 2016 and it's delayed to Q1 2016, there were no other delays officially.
There has not been a single delay of any Zen based part.
The only thing AMD has delayed is K12, and it might be shitcanned all together.
>im poor
libreboot.org
>Early anecdotal reports indicate that AMD's boot guard counterpart will be used on most OEM hardware, disabled only on so-called "enthusiast" CPUs.
I choose to believe
Same. My 8370 is starting to gimp me hard.
I'll buy a Zen CPU as early as possible.
I have preferred AMD since my first computer, an AMD 386 with 40 MHz.
Things that never happened: The Post
There was no official release date given. AMD stated that 2017 would be the first full year of revenue for Zen. They also stated that there would be limited availability in 2016.
Stop spreading FUD.
>literally the only intelfag argument left
any adult without kids that works full time can afford X99 quad Titan setups. that doesn't mean it's the smart thing to do.
>They also stated that there would be limited availability in 2016.
For any anons who are slow to catch on to this: 'limited availability' usually means final sample chips in the hands of vendors.
So which is the best i7 for 350-450€ ?
>afford
That's not the word you should use there m8
Zen was promised 2016 and of course "full year of revenue for Zen" wont be starting with Q4 of 2016 you dumb bother fucker.
now it wont even be 2017 because full year = ALL THE DAYS.
I have money stop implying I don't reeee
I dont mind. Give me 8c/16t broadwell-e with vt-d for $300, I'll buy it.
Everytime I want to believe and everytime I'm let down. Why should I believe them once again? Note that I actually believe and I'll probably be disappointed as always.
>concern troll
shills are deploying the heavy tactics now
kek
No, it wasn't "promised" in 2016.
If you actually watched that FAD you'd know that. They have said the exact same statement consistently. Only limited availability for 2016 was ever explicitly mentioned. They never, ever, ever stated that Summit Ridge or Zen Opterons would release full volume in 2016.
If only I was a troll. I'm just a poorfag who wants a nice cheap CPU.
>Not spending money on the one item you spend the most of your time on.
You may be willing to compromise on your hardware but don't shill products as superior when they are in fact objectively slower. Sure AMD is the economical choice....it always has been.
just save up, for fuck's sake. do you not have any revenue at all?
Summit Ridge was always aimed at 2017.
Also nice goal post moving there.
I live in a third world shithole. A CPU is like 10 times my monthly wages.
>Summit Ridge was always aimed at 2017.
Yes, indeed it was always aimed at 2017 for full retail availability. That has been AMD's statement from the beginning, and that is exactly what I stated.
And now that statement is FALSE
You dense motherfucker.
Now there is no availability for ZEN in 2016 making their prior statement false.
Go fuck yourself
>RX480
Why, it's still a great CPU. Still rocking an i5-3570k at stock speeds.
>#
Are you serious, core i5s have only 4 physical pleb
there's no "economical choice" in the CPU market. only what's best at your price range. I don't know if you've noticed but Intel has products from 40 bucks to multiple thousands.
in addition, there's more to a product like that than anandtech benchmarks. with Intel, there's a very real tradeoff. you have to pay a premium for unlocked chips. you have to buy a brand new motherboard every time you want to upgrade. you have to deal with the IME and all the restrictions and security issues it inflicts upon you.
you're a massive retard if you don't understand why someone would prefer to trade 5% perf (which would still be way over bottleneck in most vidyo gaems) for all the shit I've mentioned above.
unless zen turns out to be way slower than advertised, or unless Intel drastically changes their business practices, the zen lineup will be the most enticing to me and many others.
see:
Yet again, retard. There has been no delay.
AMD has not delayed anything. Sites like Ars are just repeating clickbait from digitimes which was never based on anything except someone misinterpreting statements made by Su and Papermaster.
Summit Ridge wasn't delayed. It is right on track.
>Hey, They promised it would be available in 2016
>They didn't promise it will be available in 2016
I repeat myself.
Go fuck yourself.
Skylake was a paper launch
inb4 next Mac Pro uses Zen
inb4 that's the reason for the delay
>Irrelevant information the post
I repeat myself.
Go fuck yourself.
...
>8 core CPU
>only has 4 cores
u wot
it will be available in 2016. just not for you.
God that'd be great, Apple using Intel for the last 10 years is the main reason I stay away from Macs
Im confused what is the cause of your hatred for IME? What restrictions are you talking about.
That would be hilarious
I'm pretty sure they said limited availability in 2016.
Didn't realize that this roadmap says 2017 on it.
Also where is Bristol Ridge. it also was supposed to come out 2016.
7th gen APUs are Carrizo which is out. There have been GPUs with HBM for months. Zen is limited availability.
OEMs have had Bristol Ridge chips for weeks.
Summit Ridge has limited availability in 2016.
Nothing was delayed, and once again if you actually watched that FAD you'd know this.
Carrizo is 6th gen, though they're basically the exact same thing.
Some stuff does point to Bristol Ridge being a respin though, they're still more or less the same chip in a different package.
Thats been the idea for amd
They've never done such a thing, dumbass.
do you know what it is? it's a separate core built into your CPU's die. it has access to
>all of your system's RAM via DMA
>your network
>a full fledged JVM with a hefty amount of class libs
>storage on your PC, including the ability to run software off of it
it runs even when your PC is powered off. there's no way to tell what the fuck it's doing except for some network level forensics.
should Intel's signing key be leaked (like Microsoft's secureboot bypass key was not long ago), every single Intel machine from 2006 and later is compromised.
not to mention the built in DRM components.
and on top of that, it will only run signed firmware which means you absolutely can't do shit about it. I'm probably missing half a dozen things too.
now since 2013 IIRC AMD also does the same thing with PSP, which is equally shitty. but it's possible that desktop x86 chips won't feature it.
>Carrizo is 6th gen
Oh woops you seem to be correct.
anandtech.com
wait did bulldozer not have a uop cache?
wtf lol
So Zen's IPC increase over Excavator is equal to Excavator's IPC increase over Bulldozer? What?
From the roadmap that leaked last year.
IP means in production. Final silicon being run at the fab.
Summit Ridge has met every milestone AMD set out. It was never delayed.
AMD made that claim months ago user. This graph is nicer looking though.
how much do you spend on your CPUs?
the total being about 80% is consistent with the leaked Ashes of Singularity benchmark.
hardware backdoor
Carrizo APUs show a nearly 30% uplift on average over Bulldozer. Total IPC would be slightly higher if they had an L3.
One advantage excavator has though is it uses a fraction of the power while offering comparable performance.
I find it interesting that AMD took their "big" construction cores and turned them into low power cores. Their bobcat cores just disappeared.
Well the Jaguar core arch was ever only a tiny change from Bobcat, and the Bobcat core dates back quite a ways. It was designed around 2007-2008, its an ancient arch. All the Jaguar cores need is frequency, but they aren't designed for it. Excavator can clock high at relatively low power. Thats the one thing you can say about it. Its kind of surprising that Excavator can compete at all given it still has all the cache issues, and performance in some ops actually decreased vs Steamroller from the L2 being cut in half.
Frequency comparison for fun:
XVR with AVFS
3700mhz: 22.5w~
3500mhz: 16w~
3150mhz: 10w~
2800mhz: 7w~
2450mhz: >5w~
2100mhz: 3w~
1750mhz: >2.5w~
STR
3700mhz: 25w~
3500mhz: 20w~
3150mhz: 14w~
2800mhz: 10w~
2450mhz: 7.5w~
2100mhz: 6w~
1750mhz: 4.5w~
If the Excavator core were to be featured in a 14nm design it might really shine, but then again AMD's Zen core allegedly scales better than this.
Official launch 2017, HOW EVER they will have a few chips out Q4 2016 for a few of their pardners and maybe a luck people will get their hands on one.
nothing to hide, nothing to fear
0/10 troll
>every single Intel machine from 2006 and later is compromised
Only the ones with vPro enabled. Intel didn't start putting the thing in CPUs until sandy bridge. Before that it was only on workstation/enterprise mobos.
>sick of one of the best processors in the decade
>Who gives a shit, if it performs like an i5 from last year.
That's like a 30% improvement over bulldozer, 5% improvement over ivy bridge, and it's only 5% behind skylake. That means that if they price it right and leave them unlocked, there will be no logical reason (yet) to buy the current generation intel processors.
i5-3570k checking in!
Nice, and it even beats Broadwell in IPC, running Blender, if you watch the video. That is probably one of the best cases for the architecture, but still, that is very nice, naysayers were putting it way lower.
note that i7-6900K had bigger L3 cache for that test. Not sure if AMD gave it four-channel RAM, Summit Ridge Zen will only be dual-channel.
