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

Are there any reports that they are attempting respins or process improvements to get higher clocks? It seems that threadripper gets the premium chips from the Ryzen wafers, and Epyc even more so. If TR is able to clock to 4.2/4.3 commonly on all cores, it would be a nice trickle down affect for a new stepping.

I've not seen any buy usually you have a fab or two and the focus is on improving the process. Thats why it's worth mentioning the stepping a batch number when you buy a new chip. You can then sniff out the best batches.

Seems AMD have 14nm and 14+ available. The 14nm+ Polaris cards did improve a lot over the 14nm. I'm not sure what Ryzen is using and I don't think you would be able to tell.
 
Why China Could Boost EPYC’s Future Sales

q062v7G.jpg.png

As per the report of CTIForum.com, AMD has partnered with Chinese online business giants JD.com (Jingdong), Baidu (BIDU), and Tencent (OTCPK:TCEHY) for its EPYC processors for large-scale data center deployments. Lenovo (OTCPK:LNVGY) and Sugon are also the global ecosystem OEM partners for EPYC-based server products.

Baidu is the largest search engine operator in China. More than half-a-billion Chinese people make 580 million search queries on Baidu every day. Baidu needs more processors to host this demand on its servers. Tencent is the world’s largest games publisher and it has a massive need for processors for its cloud/server infrastructure network. Tencent Cloud is now also the third biggest IaaS (Infastructure-as-as-Service) provider in China. Jingdong or JD.com is the second-largest e-commerce company in China. JD.com is also a cloud platform service provider.

These three Chinese conglomerates are already enough to probably boost AMD’s market share in global x86 server processor sales. As of last year, Intel enjoyed 99% share in x86 server processor sales. EPYC being adopted by three of China’s largest server farm/data center operators could improve AMD’s 1% share.

Going forward, AMD’s chances to return to annual net profitability could improve if it can regain 10% of the x86 server processor industry. Back in 2006, AMD enjoyed 26% market share in x86 server processors. Missteps of AMD over the last decade allowed Intel steal 25% share. The huge debt load that AMD had to suffer over its grossly overpaid purchase of ATI Technologies in 2006 meant it did not have enough R&D budget to keep its x86 processors competitive enough against Intel’s products.

The data center business is Intel’s most lucrative division. Better margins are possible in selling pricey server processors than on consumer CPUs like Core i3 or Core i5. Pricey Xeon server processors are partly why Intel enjoys a much higher operating margin than AMD.

Is anyone else still getting that odd coretemp bug where max temp goes upto 256c? Even with the latest version i'm occasionally getting this reported as max temp.

Don;t ask me wtf is going on with some of the frequencies, its clocked to 3.8 via ryzen master.

Just another ryzen quirk, theres a few of these as you'll discover :)

I stopped using Core Temp with Ryzen months ago with, not sure it's actually compatible. I just use HWiNFO 64.

Yes but IGPs always rely on fast RAM speeds since they don't have much/any VRAM, so either way you need fast RAM to get the most out of it.

Is the typical APU buyer going to want to purchase expensive fast memory though? I wish reviewers would consider things like this when benchmarking products (the same goes with lower end video cards which are reviewed on high end CPU's rather then a CPU that's priced modestly that makes more of a natural pairing with inexpensive video cards).

Indeed. An HTPC-oriented GPU may well be overall cheaper than spending extra on faster RAM to beef up an IGP in some cases.

TBH the difference between fast and slow memory isn't that much now RAM has shot up. Everything is pretty expensive.

Just had a look at destiny 2 recommended spec.
AMD need to something with developers.
Their chip is legs ahead of the Intel listed.

Old FX CPU in the minimum requirements.

Hardware Unboxed have already looked at it....

"They recommend a Ryzen 1600X but I found exactly the same performance with the Ryzen 1200, not even overclocked"

There is £10 difference in a 2x 8GB 2400 MHz to the 3000MHz kit, another £10 gets you to 3200MHz. Big % increase in performance for small % outlay.

People should do more research before quoting nonsense.
