Topic: AMD Zen CPU's: Ryzen and Naples (Read 4597 times)

now that its clear that also the naples server chips will not offer 256bit avx it will be interesting to see how they perform in compute intensive algos which greatly benefit from avx2

So the AMD CPU are good for mining?

 AMD has held the outright performance crown over Intel during 2 periods.

 (1) Athlon "Thunderbird" days - the Thunderbird was a hair more efficient per clock vs the Pentium III across the board AND the top Thunderbird chips clocked HIGHER.
      Eventually Intel came out with the Pentium 4 and got it clocking high enough to overcome the lower IPC handicap - AMD was ahead for 2-3 years though.
      The Athlon "Palomino" showed up a bit too late to hold on to the crown (though it kept things CLOSE for a while), and didn't scale fast enough to stay competative at the top.

 (2) Athlon 64.
      Intel had NOTHING competative prior to introduction of the "Core" line.
      AMD had another 2-3 year lead and for the first time made some serious incursion into SERVER manufacturers (the Thunderbird managed some SMALL gains but nothing major).

 AMD was also very very close in the K5 vs. Pentium days, prior to Intel introducing the MMX instruction set on the second generation Pentium-166. That timeframe came down to instruction mix a lot - Intel won on floating Point operations by a lot, AMD won on integer operations by a much narrower degree.

 I don't count the 386 and earlier days, when the IBM-forced "AMD as second source" agreement was still in force.


 I honestly don't see Ryzen making any serious dent in cryptomining though - there are too few CPU-mineable coins and ALL of them except Monero are way too small (and even Monero isn't real competative for CPUs vs GPUs) to make it worth spending a lot on Ryzen based hardware.

dude.... look that opteron chips actualy outperforms xeon chips on the same price range concerning mining... and my cheap shitty amd  a8 5400k  has same performance per core than those of an i7....

That's why im holding off this time and buying one two of the 4 cores once there out a month and tested the FX CPU AM + 3 were ok for my use but they had some disappointing set backs if you tired to over clock and game with them other wise they worked fine for me .

My bad took it wrong i agree Intel has been king to long i have bought a few Intel chips and they are good I guess but what I use my PC for i don't notice any difference  between the two ..

Never ever will do! Did that mistake in ~2002

Maybe my next PC is AMD based.

Take your fanboy hat off and read again. I didn't say cheap amd, I said cheap CPU, cheap intel is no good either.

The only thing I said about AMD is it's hard to believe the ryzen will be cheaper and faster than intel for
cpu mining. Intel has previously benefitted from hyperthreading and better power efficciency and better
implementation of AVX2. In Ryzen AVX2 will be faked, I don't know how or what effect it will have on
performance. They have implemented hyperthreading but this first attempt will not likely compete with
Intel yet. Can they beat Intel on performance? Not likely.

I wish they could. Intel has no real competition in the workstation and server market and that is not a good thing.

Can AMD compete on price. That's up to them. I wish they would because it would put pressure on Intel prices.

I am going with AMD for the longer chipset cycle time, nothing more annoying then having chipset and sockets retired every few months.

why not at one time AMD was king even over Intel in fact i remember CPU wars till AMD wtf up ... then they lost out big time and Intel took over why cant AMD do it again ..? ..

AMD is a lot different then they were when they all most went out of business a while back and i was told are working on the next die of 10nm ..

 I can AMD did this or that and I'm sure you would try to down play that so i won't brother but I am holding off for just the reason you stated to see how it holds up this time ..... but to say they can't because the CPU is cheap in price doesn't mean it is cheaply made or it can't handle it beyond Intel or match it.. or it's cheap because of the price ...

Cheaper and faster than Intel, that's hard to believe. A cheap CPU is no good for mining because of the overhead
of the rest of the PC. You can't put 6 CPUs in one pc like you can with GPUs so you want the fastest CPU you can get
to get the most from the PC.

I would like to buy a new CPU as well,the problem is this upgrade will certainly require a new motherboard
what I liked about AMD CPUs besides their price,of course
was their socket backward compatibility,AM3+ lasted for what ,6 years already
Intel produces better CPus,but they also make you change your motherboard each time you wanted to buy a next generation processor
lets hope Ryzen is not just hot air paper tiger and it will be able to take substantial part of the processor market off of Intel
competiton leads to progress

I'll probably buy a Ryzen 3 for just general use and not for mining and sell my aging 4790... Works nice but I'd like to use a newer CPU. Would also get me a few extra bucks for GPUs. Overall just happy AMD is finally stepping up their game against Intel and prices are being slashed all over the place with CPUs.

I'm gonna wait for the 4 core ones to come out @ 150 ,i can't see me buying this one coming in a few days or the 8 core one that can actually be used as  16  like Intel does now .. if it hasn't yet .I'll be happy with 8 cores or 4 cores with 4 vm cores .. and @all most 400 bucks i don't need 16 cores or 8+8 VM cores I know it is a lot cheaper then Intel but would rather wait to see how well they hold up also , i did buy a few  FX 8 cores way back when they first came out day one ...not gonna rush it this time  ... ...plus I'm about to buy a A4 136 mh ...this year is turning into a very good year for me and my family.

there is a fresh article about the new AMD serises Ryzen based processors:
http://www.trustedreviews.com/news/amd-ryzen-specs-performance-release-date
according to the article ,the first  three processors are available for pre-order starting 22.02.2017
it is quite remarkable that their CPUs are going to be 2-3 times cheaper than their Intel counterparts
yet they are beating them in tests,of course it is all  on paper only,we have to get our hands on one of them babies to be able to judge
but it is looking very promising
as for the CPU mining-there are some coins that would benefit from a higher speed,low power ( 95 w TDP is amazing) CPU
but I doubt it would make any impact,after all GPUs have proven to be the better and more efficient option when mining altcoins

My E-5 2667 V3 ES cpu's mine about the same H/s as my unmodded RX480's , they all do about 565 -575 H/s each.

And the prices were comparable.

But that is with used cpu's vs new gpu's so it can be done but with gpu's you don't need an expensive motherboard, even used a dual 2011-3 board is pricey.

I bought my motherboard new at $370.00, AsrockRack EP2C612 WS.

If I was solely wanting to build mining rigs I could have bought a cheap 1150 board and a couple of gpu's for that price.

For the price/performance gpu's cant be beat.

I am really interested with the new cpu's AMD will be coming out with mainly for the competition that will hopefully force Intel to drop prices and that will drop prices of used server stuff.

My main rig is a dual Zeon E5-2667 V3 ES setup.  The E5-2667 ES cpu's have 35 mb of L3 cache each, 70 mb total, so using the general rule of 2 mb per thread to mine monero I am able to run all 32 threads plus two RX 480 4 gb gpu's and my hash rate is ~2300 on a pc that I can still use every day for my regular stuff like surfing the internet watching netflix and everything except gaming all while its mining away.

I did not build this as a dedicated mining rig, its my main play/doeverything pc.

When I build my next main rig this one will be a dedicated mining rig for monero, the board has 7 full length slots plus a whole bunch of pci-e lanes with the dual Xeons and I would like to try more than 7 gpu's on it eventually.

So I highly recommend server grade hardware IF you can get it priced right.  

Only certain applications benefit from SIMD instructions of SSE and AVX, and I din't think servers are high on the list.
SIMD is great for things like spread sheets that involve the same operation being performed on multiple data, and of
course, graphics applications. If AVX2 is not in the desktop version I doubt it will be in the server.

Many CPU oriented algos are so because of their memory bandwidth requirements. Those algos can't use all the compute
power available because they are slowed down by memory accesses. This severely affects GPU ming performance but
also affects CPU performance at a lesser degree. Algos like cryptonight are maxed out with only 4 threads on an i7.
The compute power of Ryzen may not be a factor in CPU mining, it may all come down to cache size and memory
bandwidth.

if coin can be mined with CPU and GPU both, I don't really see the future of CPU mining there. And for CPU only coins, they are usually forgotten by traders in few days. Fact is that GPUs are just better than CPUs at mining for same invested money.
