Exactly, but I still think that comparing EPYC to older Broadwell Xeons isn't very fair, since Skylake-X is quite a bit better (more L2 cache, better IPC, AVX-512 etc)

While that's fair, there are no benchmarks for AMD to compare against.  The only benchmark is the current gen of Xeons, so it's not unreasonable.

Does this say what the performance stats are based on? Can't find it in the article or pics.

Most likely an integer/float arithmetic test. That's were zen excels.

I would also, but make sure the boss isn't watching, or if he is tell him the rival company is beating their scores and hope he has a competitive nature and enjoys some joking around with thousands of dollars of equipment because go big or go home. 

hell yah, cant have that other company winning the benchmark battle!

Why is virtualization bad? Are there pass through issues?

yah passthrough issues with PCIe IIRC

As Linus mentioned, it might be two but the principle is still the same. 

but its not a single CPU anymore, not that i wouldent want to see 32 gamers one tower though

Idk, Linus once said on the Wan Show that the creators of UnRaid told him that virtualization on Ryzen isn't a very good experience

It was an issue because of how IOMMU was handled, they are fixing it or maybe already did in the new update.

How isn't it fair ?  It's the best Intel has to offer as of right now. People can't make numbers up for not yet released CPU.

By this logic it's not fair for nvidia to compare their cards to r9 fury X's and RX 580 since Vega beat what AMD currently offers. But as we all know, if amd didn't want that they should have released their cards already

I maybe missing something here. 

the lowest tiered EPYC cpu will be >$400. But for roughly about that price, one could buy a ryzen 1800x with better overclocking and lower TDP. 

So I understand that these are server grade chips, what I don't understand is the purpose behind the 8C/16T Epyc cpu. I suppose the 16C/32T threadripper cpu could also fall into the same boat

Why would they build a product that competes with another one of their own products?

They could use the mega case from corsair, having the mini ITX build for the game server, and the other dual CPU quad GPU system for the players. They could easily make a zero latency cs go 10 vs 10 player game with that.

While I agree that the 8-core variant is a bit puzzling, it's not really competing.  There are use-case scenarios whereby someone might not need much processing power, but does need the additional PCIe lanes and memory bandwidth that Epyc offers.

 

*EDIT*
Remember that Epyc offers double both the memory bandwidth and the PCIe lanes of even TR, much less that of Ryzen.

That's actually exactly what it is.

 

According to wikipedia SpecINT of CPU2006 software suite uses a combination of Interger Performance Testing(CINT2006) and Floating point testing(CFP 2006).

 

I just don't know how I've been oblivious to this software for my entire life.

A PCIe storage server would not need a lot of cores but would love RAM and PCIe lanes which the 8 core part has 8-channel ram and 128 PCIe lanes.

and amd will just slap another zeppling die on to the substrate and beat them ahah

"Starship" was on their roadmap since the Zen architecture was figured out, which pointed to a 48c/96t server CPU. So Zen 2 is either a 6-core CCX design or they're expecting to put a 6-package CPU together in 2019.  

 

The 8c/16t part surprised me a little, until I remembered that the sucker is still going to have all of the PCIe lanes and the massive memory through-put. Depending on the workload, that's really useful for some folks.

Performance looks promising, but:

• AVX performance is clearly not taken into account
• They are comparing EPYC to older Xeons, we don't know how EPYC stacks up vs Skylake Xeons

Skylake-E will not be cheap.

if they are compatible with the existing socket then it is a high chance it is 6c CCX which would make AM4 parts be up to 12c TR4 up to 24c and (what ever socket epyc is) 48c

 

reasoning behind this is that they would still use 1 channel memory per CCX.

Oh god. intel what u gonna do

stress release CPU with 48 cores, but to use more than 24 cores you need to buy additional 3000$ priced CPU raid controller.

The next thing intel will do it you need to buy keys to unlock extra PCIe lanes.

And it won't be officially supported, like 3 and 4 way SLI

Well, you aren't running a server application feeding 100s of users..

[yian88]

Over clock 32c/64T to 4.5ghz on water 128gb 3200mhz RAM 8channel, 100GB/s+  bandwidth uhuhuhu.

Optane like Drive 2TB nvme, with 2x Vega/Volta,  with Vulkan multicore API playing Total War Medieval 3 simulating 100k units  vs 100k units real time battles.

Now that is gaming, the future is exciting.

 

 

 

What are the prices thats its important are they competitive with intel or expensiv?

I don't think you can get 32 cores to 4.5 GHz on water cooling

I guess it's just that it is on the server socket SP3, so it works on those server motherboards. AMD will be hoping to sell them in large quantities to guys like HP and Dell who ship out servers to be placed in data centers. Those guys won't build serious servers around AM4 or TR4. Apart from the featureset the platform has to be reliable enough to just throw into a server rack and work 24x7 for years.

It'll be a while before AMD makes too much progress in the Server market, but there'll be room.  That's a LOT of cores at a much lower, generally, price than Intel offers. The important part about Intel's server stack is that they have a huge list of server products available by list.  And all of them can be semi-custom bought as well. An absolutely massive "get" for AMD is if Amazon, Google or Facebook are interested in buying volume.

 

I also expect Linus to get a 2U server and OC it to 3.9 Ghz all-core. HAHA.

They were having significant virtualization teething problems at the release of Ryzen. However they have have had significant success in solving those problems since and have had dedicated teams working with various companies on the issue. Whether any significant issues remain is difficult to say.

 

 

Addendum - Also, someone at Intel had to have shat their pants when they saw the leaked prices.

ive never had any problems with vmware or virtual box
