Asus Strix doubles down on AMD with first eight-core Ryzen laptop

 

HPE's AMD EPYC-Powered VM Server Breaks Benchmark Records:

 

According to HPE, the benchmarks were attained using AMD EPYC model 7601 on ProLiant DL385 Gen10 systems, which are available with up to 64-cores, 4 TB memory and 128 lanes of PCIe connectivity. For the SPECrate 2017_fp_base benchmark the HPE/AMD combo scored 257, and for the SPECfp_rate2006 the score was 1980. Both were the highest ever two socket system scores for their respective benchmarks.

 




#1197940 Too Many Damn Lakes! Intel's coming CPU's

The Price of Intel Corporation’s 10-Nanometer Failure

 

Intel is now claiming it will "introduce" its first 10nm products by the end of 2017, with serious volumes coming in 2018. Credible leaks have revealed that Intel is targeting availability more in the middle of 2018.

 

A delay in the mass-production start from the end of 2015 to the end of 2017 is a delay of two years, or roughly a full generation, at least back when an Intel generation was defined as roughly two years.

 

As if it couldn't get any worse, by Intel's own admission, its first- and second-generation 10nm technologies -- 10nm and 10nm+, respectively -- will offer worse performance than its upcoming 14nm++ technology . Intel says the company's 10nm technology won't open up a clear performance lead over its 14nm++ technology until its third iteration -- known as 10nm++ -- which should go into production sometime in 2020.

 

Interesting article. I can't seem to get my head around it as Intel are unstoppable, or at least appear to be. Even... how the hell how does a smaller process not increase performance?

 

Seems like this might be enough of a struggle for them for AMD to catch up and we can have a bit more balance in the market place.

 

Writer of the article has shares in Intel, so it's not a bash piece.




#1197858 iNeed to upgrade - which Intel socket 2066 motherboard?

Posted by SceptreCore on 18 November 2017 - 05:40 PM

The advantage in photo rendering tests are even less than the video ones, and that's likely the workload that'll be done.

 

Coffee Lake is out of the question. If the 8 core was out.. which is what the Z390 board is going to support, that might be different... but would it still use the ring bus architecture or go to mesh like Skylake X and lose its edge? Regardless it's still not here.

 

7820 or 1700 would be good buys and arguments for both. But for me, -50% cost for the 1700. it's not that far behind in the rendering workloads, and there's an upgrade path for Ryzen+

 

But if g_day didn't want to swap the CPU out and sell the old one later... then 7820 would be the go.

 

 

EDIT: In my silly opinion of course.

Trouble with that offer of advice is there is very little understanding of the astronomy workflow and which hardware optimises its processing requirements.  PixelInsight (which I don't use) gives some benchmark capabilites, but I use DeepSkyStacker or CCDStack.  The authors of both have said it is multi core enabled (but no GPU smarts) and very little else to go by.

 

I have searched the Australian and US astronomy websites of over 30,000 dedicated amateur astronomers and spoken to the makers of many of the Astronomy software tools - and there isn't clear consensus!  When you say the community can help me - remember clearly - I helped start this community and am one of a small set of it's initial go-to folk for all matters technical.  But my knowledge doesn't give me insight as to say whether a very heavily raided PCIE storage device at any cost for scratch files would be better than one or more large RAMDrives.  The workflow tools within PixelInsight show you actually do best from having four decent sized RAMDrives than any other configuration - with a lot of debate even from its authors on why!

 

My needs are closer aligned to Workstation for a sub-class of 3D rendering needs - with the extra constraint that the GPU isn't heavily used yet by the makers of small, but very expensive Astrophotography programs - CCDWare family, DSS.  Whilst PixelInsight has started to use it, Registar and many other haven't yet.  All the Astronomy data acquisition s/w tools - The SkyX, PEMPro, ZWO Camera control suites, PHD autoguiding, auto focusing and V-spline, Plate solving, Dome management etc are well set up and working fine.  There challenges aren't data prcessing merely faultless data acquisition.  It's the occassional data crunching load that is the X-factor for most astronomers.

 

It's trivially simple to set up a big rig for gaming.  Game development has really simple and very well known hardware needs.  The interaction of CPU, GPU and memory latency in Directx11 or 12 or OpenGL games are thoroughly understood and catered for.  Astronomers needs far less well so.  The arrival of very fast, relatively inexpensive CMOS cameras that have shallow light wells (20,000e - 40,000e) but extremely low readout noise are game changers!  It used to be you needed $4K - $16K CCDs that were very noisey and very deep electron well for each pixel - and so had to be very, very deep cooled to reduce dark currents; they had fat pixels with really deep well to shoot hard targets with a decent signal to noise ratio.  They had poor frame buffers and slow USB 1.1 or 2 readouts so amp glow was a factor.  Nowadays sub $2K CMOS from say ZWO with USB3 can bring shooting light frames of your target down from requiring 20 x 30 minute shots to 300 x 2 minute shots.  The signal to noise goes through the roof in that situation - thanks to the mathematics of noise sampling.  But the need is to combine that data for each of Red, Green, Blue, Luminance and Hydrogen Alpha, Oxygen II and Sulphur II filter channels.  So you may have 300 x 10 MB RAW images to combine for each of seven colour channels, for each target, for each run duration (30 seconds, 2 minutes, 4 minutes etc) before you start the channel combine and deep processing is Photoshop CS or MaximDL or both!

 

So I have opted for an all round rig that should do everything credibly, but allow for movement once the software or hardware available adapts.  Need more CPU then I would go to a I9 7940 - 14 core beast.  Would it beat the Threadripper 1950 for my workload - I certainly expect so given the price differential.  Would it beat a dual CPU 60 core Xeon Workstation from 2012 - possibly it would get its bottom paddled!

 

I may find that no sane amount of compute will bring my needs down to real time processing of a few minutes per imaging target.  Fine you just batch them all and queue them to run before you go to bed and look at the results in the morning.  If they take 4, 8, 12 or 16 hours to complete - so be it!  So far I have only tried runs of about 30 light frames (the actual picture of your target) plus matching master dark frames, flat frames, BIAS and flat dark frames.  Once the light frames grow into the hundreds I don't know how the various software sets will scale.  All this has to be temperature calibrated too (lights, darks and flats) - but Ihope to avoid this by having everything calibrated Summer through WInter to -25 to -30 C.

 

So with this deeper insights to my needs can you really offer far better advice than given to me over the past six months?

I meant no disrespect mate, I'm looking at it from a bird's eye kind of perspective. When you said it's "gotta be better than your old Core 2 Quad", I am just trying to get myself up to your speed. Then you went and said a whole bunch of words to put me in my place.. and indeed it did.

 

From my view I just want to make sure that you want to invest so much dosh for something that you've been getting by with on old beater. But i suppose you've already calculated the cost.

 

As regards where these products are priced... AMD has come in to seriously undercut Intel. They priced their 16 core at the same cost as Intel's 10 core, and it dominates it just about every measure, trading blows with AMD's 12 core offering and not being successful there either. More than likely AMD will support their socket longer than Intel does, because that's what they usually do. From all the tech reviewers I've watched, they all say that Threadripper is the most compelling offering, and a couple of them built Threadripper systems for their own professional work. So with that information, it's really up to you... you will be happy with both I feel, but one will definitely leave you with more in your pocket.

Total box build including Win 10 Pro - a bit shy of $6,000 (excluding monitors, keyboard, headphones, mice, UPS etc).  I am leaning towards the Gigabtye X299 AORUS Gaming 7 motherboard at present!

What are you going to be doing with the machine?

During our pre-briefings on Ryzen Mobile, it was asked why the two new APUs were using the 2000-series numbers, and not the 1000-series numbers like the desktop parts. It was assumed by the press that the first generation of Ryzen would all be under the 1000-series, including the mobile parts. The response given by Kevin Lensing, AMD’s Corporate VP of the Client Business Unit, was that so many of the design ideas that AMD wanted to put into the original desktop Ryzen (but couldn’t due to time) eventually ended up in Ryzen Mobile, such as the updated precision boost. While there are no architectural changes to Zen to warrant a next-generation microarchitecture name, this version of Ryzen’s periphery (i.e. the power) was more in-line with an original vision and had to be presented as such. This is why we have Ryzen 7 2700U, rather than a Ryzen 7 1700U. He would not comment if the true next generation Ryzen desktop naming would still be the 2000 series, or if we would go straight to 3000. Who knows, it might alternate.

AMD wants Radeon Vega and Ryzen on 12nm LP process next year

 

As confirmed by Tom’s Hardware who spoke to Papermaster directly, AMD will switch both Vega and Ryzen to 12nm LP process next year.

 

This means that the slides published by AMD are no longer valid, as 14nm+ has now been shifted to 12nm. The so-called Zen+ might be the architecture behind Ryzen 2000 series, which should launch in 2H 2018. The other theory would be xx50 series, eg. Ryzen 7 1850X and so on, but we don’t know how would that affect Threadripper.

 

When it comes to Vega, AMD has never confirmed Vega 20, but we knew about it for a long time. The slides also mentioned 14nm+, which should also be now outdated.

The longterm roadmap outlines the plans for 2017/2018/2019. By 2020 AMD wants 7nm and 7nm+ products to be available. It appears that next year is a year for refreshed architectures with big upgrades coming in 2019.

Posted by SceptreCore on 12 September 2017 - 10:51 AM

must say im kinda envious i haven't had a amd system since opteron 170 with bh-5 & x1900xtx cf
hurry up and bench it :)

But that would have been an ATI card then, not AMD.

 

;)


Well I sold my GTX 1070 for $4 more than what I paid for it (thanks miners).  Bought the RX 56 and it was $18 more than what I sold the GTX 1070.  Basically, Im doing another side upgrade so I can play with new stuff.  RX 56 has been great even with crap drivers.  Most things were about the same performance as my OC 1070 while running stock.  

 

I decided to go ahead and flash the card as I was not able to get over 1500mhz on the core and the HBM2 ram didn't like anything over 800mhz.  I used the air version bios of RX 64 not the liquid.  It took without any issues.  Now when I run turbo mode it clock around 1560mhz and the ram is 945mhz.  I've been able to OC into the 1600mhz range but not sure its limits but know that 1700mhz is a no go.  If I can figure out the limits, I might try to flash to the liquid version as it gives even more watts available but need to test for current heat and the fan profiles to keep it under 80c.  

 

Really a neat card and cant believe I have an all AMD system again... Super happy about that!

Good on you for supporting AMD.. but personally I would have stuck with the 1070, as it's quieter, cooler, and uses less power... my two cents.

#1195792 Ryzen: Built Another one!

Posted by SceptreCore on 07 September 2017 - 02:59 PM

 

I love your support for AMD... but those games all run better on Intel's CPU's. Did you consider an i5 7600?

 

That's arguable.

Well, no it's not.... on those games, sure;

The catch is that those games won't bottleneck on AMD, They'll all smash 100+FPS on a 1050ti, despite the SLIGHT lead to Intel.

 

Where as, on games that are heavily multi-threaded (PUBG, Battlefield1, Tomb Raider, etc), the Ryzen is easily on par (sometimes with a slight lead).

 

AMD also has the advantages of:

Socket 1151 is MUCH older. I'd expect there to be a new socket in the near future.

The Intel is more expensive (about, $20, so 10%; and it's not 10% faster).

It can't be overclocked in the future.

It has more threads for multitasking.

AM4 motherboards are WAY cheaper.

 

 

I do understand that Intel (currently) does better in games;

But it's only by 5% on average, the tech is early, Vulkan is young, and the AM4 socket is here to stay, giving a future upgrade path.

Also! The lead only seems to show in DX games.

 

Besides, the CPU cooler alone is worth it :P

Screws not push pins, my savior!

 

Well all of what you said is true... I guess I get a bit taken in by numbers represented on a graph. Cursed marketing ploys!!

 

The best advantage of all is of course the upgradeability with future drop in Zen products.
