Zen processor AM4 Desktop

So I recently was online looking to see what AMD where doing in terms of there new processors and come across the zen processor, anyone have any up to date information on this? - seems as though it could be a good bit of kit to compete with Intel Haswell CPU's and Skylake?

Re: Zen processor AM4 Desktop

It wont be competing with Skylake. it will be competing with Kaby Lake.

It looks like a decent piece of kit. AMD is always hard to judge as they usually launch poorly and improve as the drivers etc get optimised. I used to run nothing BUT AMD back in the day as they were BEASTS compared to Intels offerings. They have fallen short more recently and Id love to see a return to form.

The ZEN has been seen in server architecture but the specific SOC that consumers will see- "Summit Ridge" will be demoed this month- should be interesting.

Re: Zen processor AM4 Desktop

in our limited family experience, AMD were always way noisier than intel equivalents - ran hotter, used more power, so needed more extreme noisy cooling solutions.

 they seems aimed at the so what if it sounds like a jet engine - gimme more fps & I'll crank up the audio type of gamer- maybe that's unfair nowadays ?

i know that  over time I've offload 2 maybe 3 different ATI/AMD graphics cards back onto ebay for being too noisy. my nvidia cards are pretty good. I have one passive silent  one, one Strix design that only spins the fans when hot... and one Geforce960 in a liquid-cooled-cpu alienware X51 that's also pretty quiet.

 My Son's last PC was an AMD quad core- that came with four case fans linked to  a four knob front control panel, though probably that was mostly for show- 2 have died anyway, or the panel pots have failed, it still games ok.

Re: Zen processor AM4 Desktop

AMD's official stance is that Zen has roughly the IPC of Broadwell, so that means clock for clock it will be slower than Intels current line up. It remains to be seen what clockspeed they can actually ship though, or how hard they'll push the power consumption to be competitive. It seems unlikely that they'll take the performance crown, but it may be close enough to at least worry Intel into getting more price competitive again.

As for AMD being a noisy option. I'd say that's only been true for the past 5-6 years with the release of the bulldozer chips. If you go back to the early days of the Pentium 4, AMD were totally dominant. They were faster and used way less power, it was Intel who were the crack it to 11 company. It's all swings and roundabouts really and every so often it flips between who is the better of the two.

Re: Zen processor AM4 Desktop

Well from what we've seen so far it appears the IPC is on Broadwell-E level, besting the i7 6800k and snapping at the heels of the i7 6900K (a £1,000 CPU thanks to Intel's current Ben Dover pricing scheme)... Summit Ridge (the Ryzen desktop chips) will release in January by the looks of it, starting with the 8 core / 16 thread halo model. The lower SKU chips and APUs will follow through the year. The server stuff (Naples) will release H2 2017, and includes 64 core / 128 thread behemoths. Smiley Surprised If they get the base clocks decent on release (it's looking around 3.4GHz or so for the 8/16 SR) and their new turbo implementation works how it's said to, they're going to be very interesting indeed.

My money is on:

Top binned 8/16 to compete with i7 Extreme (Broadwell-E)
Normal 8/16 to compete with Kaby i7
Then the 6/12 to compete with i5
and the 4/8 or 4/4 to compete with i3

Those, with Broadwell-E IPC, will be a very interesting shakeup for the CPU industry, finally. Hopefully they can push Intel to climb down from the current ridiculously high pricing. Similar IPC and more cores to the Intel equivalent (if pitched as above) will really let the cat amongst the pigeons even for the diehard fanboys. It also allows AMD to keep the pricing realistic (for their bottom line, not the consumer) while still being very competitive. As much as a really cheap chip with high performance is what a customer wants, long-term AMD need money in the bank to keep momentum and development flowing. 

For those who don't know, Zen (now Ryzen) has a turbo mode that - unlike Intel - will scale with the cooling you provide. So unlike a 'traditional' chip which may have a 3.4GHz base and turbo boost to 4GHz, the (Ry)Zen chips will boost higher and higher with better cooling. So maybe 4GHz on air, 4.5GHz under water, 5GHz on LN2 etc etc. All while bettering Intel's 6900K for power consumption under full load. Very interesting stuff, and I can't wait to see the reviews and benches on release. Jim Keller has always produced the goods when he designs CPUs, so fingers crossed.

Re: Zen processor AM4 Desktop

Nice post RainmakerRaw

Id REALLY like to see this line up  "booting Intel up the hole" as we say round these parts. Im currently running Intel by default after AMD slipped back in the last few years.

Ben Dover pricing scheme indeed...I LIKE computers but I really cant justify the spend on a current gen i7

Be interesting to see how one of these new chips married to a Radeon card performs....

luckily for Gamers there is sill no need for one. I am not aware of any mainstream game which plays better on an i7 than on a similar speed i5, other things being equal, and nothing that uses >8GB Ram in normal play

Re: Zen processor AM4 Desktop

What AMD really needs to do is work with various chipset producers and work on getting PCI-e 3.0 and 4.0 to be compatible with AMD boards.

Being bottle-necked with 2.0 speeds on 3.0 cards is not fun and in my opinion really hurts them.

Which is a surprise considering they manufacture GPUs that run on 3.0 buses.

Majide!

The boards previewed at CES today are PCIe 3.0, starting at 24 lanes. Here's a quick look at some of them.
