Ok they finally got me. I am confused. How do epyc and Threadripper and ryzen compare? Is epyc or threadripper now the HEDT platform?!

EPYC is servers

threadripper is HEDT (so PCs that are powerful but not servers)

Thanks a bunch guys!??

It's kinda the entire headline for Epyc: it's good depending on your workload.  Most people don't understand that it's no where near a slam dunk.

that is true and the people who will be buying these server PCs normally know what they are buying so will know what CPU they will need but we will see what happens but AMD is looking very promising on becoming profitable this year

So can have 1.872tb  for a ramdisk and 128gb of ram

Because I forgot the metric thing

[cj09beira]

seems like amd will allow for 20w over the rated tdp, which the costumer can change in bios

I don't understand how enterprise per-core licensing works, but if they don't offer anything but a %8 core configuration does that mean if I only "want" 28 cores I would have to buy the 32 core part and pay licensing for all 32 cores?

Wait a second does this mean that we are going to get a new X-gamers 1CPU like an 8 gamers 1 CPU which is actually only using 1 CPU or a 16 gamers 2 CPUs which would also be awesome

1CPU 16 gamers should be doable on an EPYC server. 128 PCIe lanes is enough for 16GPUs to run at 8x and 2 cores 4 threads for every player.

yea it's possible but I was thinking about 2 32 core CPUs and having 4 cores 8 threads each which would be great for gaming and 16 GPUs would be easily possible.

 

 

By the way does anyone know if these CPUs have onboard (yes I know that;s not a major thing but I was just wondering)

thats probably referring to software, there is software that you pay a license per core so a 8 cores with a bunch of memory is great for those cases (its expensive and the usage of such license has been ryzing)

they dont, but most server boards have some sort of graphics chip to control the server

nah none of these have onboard graphics as you'd expect from server and workstation grade components. Not even Ryzen has them. But I think APUs with Ryzen and Vega are coming.

early power figures, 128 threads less than 500w at 100% load

100% AVX 256-bit load as well. That's rather impressive.

Conspicuously neglecting to include any latency numbers.

 

Also looks like AMD is fucking with the benchmark numbers:

 

Oh gee let's just exclude a MASSIVE reason to use IA in the first place (software and compilers being superior) and handwave it away.

That's not a good look.

 

Always pay attention to asterisks.  

[cj09beira]

what 4TBytes of memory look like

[cj09beira]

People were worried about cooling, look at the size of the coolers, they can easily fit in a 1U server

(don't forget in epyc your heat is spread across a much bigger area, so cooling it is easier )

AMD's footnote actually goes into a lot of detail; and considering the major partners AMD has just picked up it's safe to assume their tests were verified.

Microsoft and Baidu are hardly going to sign Billion Dollar contracts and partner ships before thoroughly testing and verifying performance and stability compared to Intel's offerings.

No its for server use so for something like a Plex server with loads of transcoding

Even my crappy little i3-3220 does just fine in a Plex server, multiple 1080p transcodes while not making the computer totally unusable locally.  I want to toss a an ivybridge xeon into it, pretty much just because I can/moar coars, but as of now it's not really struggling at all.

 

No idea how many clients you have using your Plex box though, and obviously 4k content is going to be a way more intense load than my 1080p collection.

Sure, but it doesn't change the fact they fudged with benchmarks.

Who buys 32 core CPUs for desktop use?

If I gave @leadeater a use case for getting a 7980XE for home use, damn sure I can create one for a 32 core part.

Well yeah thats my problem i have 4K content on my server with a couple of people (5) so load is pretty high

I mine ethereum just to use my PC as a heater, there's always some use case for something no matter how stupid

Yeah, but mine was practical, if you only have the space for one tower at home.

One could also say, it's them accurately representing themselves against the Intel Compiler; which was so devastating to AMD and VIA processors the FTC fined the crap out of intel in the past.

 

Even so, we'll out from third parties if AMD's numbers match up correctly when using a neutral compiler compared to Intel's.

It makes my room warmer in winter, don't get much more practical than that
