[quotemsg=20423469,0,2331410]i only have 8c 190x thread ripper , but im not getting no high latencies from die2die and my chip has two and only 4 cores each, 2 dies, and to sepaerate CCXs for both dies, and max latecy i see is like 107ns but thats on like a very large memory caching. 4gb+ not acuall but i forgot the resuts, but intels "INTERNAL" (FAKED) Tests///theyve don this before? and i now it?[/quotemsg]
So you are saying that you get different latency results on a desktop based system than a server based system?
Seems plausible.
[quotemsg=20423476,0,2331410]any i bet 100M $$$ that intel isnt even running the Ram @ anything besides 2133Mhz, i bet my life on it[/quotemsg]
States in the slides that they used DDR4 2667. Reading does help a lot.
In fact, they also used 1 DIMM per channel to get the most memory bandwidth per system. Look at slide page 18 and 19.
[quotemsg=20424004,0,1425755]Intel cheated as usual. Intels properly compiler isn't something that most clients will use anyway & compared to open source ones (GGC, VLLM) which they will it gives some 20% performance boost. This actually EPYC right back into competition.

All of this ain't all that important as ARM server's with NUMA support are coming to finally brick X86.

& with a little help of the good old vet's this time around Intel won't have even a compiler advantage to drag about.

Fun part that makes this even nostalgic for me is after long time Intel monopoly we are back where & how it all started.[/quotemsg]
You realize the majority of these benchmarks are third party programs and industry standard benchmarks meaning they probably didn't use Intels compiler.

If you believe this massive song and dance 'marketing wall of propaganda' from Chipzilla, I'm thinking you also believe that "Tax cuts pay for themselves" or
"The Moon landing was fake" or
"The check is in the mail"
:lol:
Otherwise, Anandtech did some benchies back in July ...
Sizing Up Servers: Intel's Skylake-SP Xeon versus AMD's EPYC 7000
It paints a different picture, and kinda set the table for an Intel 'bombardment' response of some sort. Can't say it was not unexpected.

Those are very different benchmarks. These are for Datacenter servers, not database servers. Very different roles and performance numbers.
[quotemsg=20425955,0,165447]Intel has been really busy finding benchmarks that show the weaknesses of AMD's EPYC product compared to their own.
Intel is just trying to hide the fact that with the launch of their new Xeon Scalable Processor there is (almost) no improvement in performance per dollar compared to their previous generation product. I really hope AMD will take a significant market share so Intel cannot afford repeat this again.
Also both AMD and Intel should make good performing 8-core parts for 2 socket or 16-core parts for 1 socket systems for a good price due to the core tax that Microsoft introduced with the Server 2016 pricing. Both AMD and Intel's new lineups only feature 2.1GHz base parts in 8-core with a reasonable price which is very disappointing.[/quotemsg]
You mean like any company does when comparing? Do you really think Intel would show their product failing vs AMD? DO you think AMD would? What was the last AMD marketing slide that showed off their CPU/GPU losing to the competition? None?
Companies market their products. Their goal is to sell that product.
Imagine going to buy a car and the car salesman tells you "The other car is better but you should buy ours. Look at how the other car performs better, gets better gas mileage and has better features. Don't you want to buy my car now?". That's not how marketing works.
