[Guru3D] AMD Launches 64-core / 128 Threaded 2nd Gen AMD EPYC Processors

Quote:
An exciting day for AMD as they introduced its second generation of Epyc server processors. Epyc 7002 processors (Rome) get a massive 64 cores for its flagship models. That's twice what it was a year ago. These puppies can do 3.4 GHz as long as a maximum of eight cores and have an all-core turbo of 3.2 GHz.
Epyc Gen 2 is based on the all-new Zen 2 (7nm) used in Ryzen 3000 processors for desktops and thus bring a healthy IPC increase as well. Of course, that also means Epyc brings support for PCI-express 4.0 and has 128 lanes available. 256G / s of PCIe bandwidth is therefore available in both directions. Each Epyc CPU has eight DDR4-3200 memory channels, in which a maximum of 4 TB of working memory can be installed per socket. The CPUs are based in the chiplet design, meaning AMD has a separated IO die next to the 8-core dies. AMD also emphasizes that it has a safer architecture compared to the competition.

Previous Thread title: [Guru3D] 64-core AMD Epyc 7742 (Rome) CPU Benchmarks leak

Quote:
The new CPUs will be announced tomorrow, but got leaked by an anonymous user with an Epyc 7742 which we can only assume is the flagship model of the new series.
Epyc 7742 would get reportedly 64 cores and 128 threads at a base clock speed of 2.25 GHz. The boost clock seems to be 3.4 GHz, a lot higher then what got leaked and mentioned a few months ago. The chip has a staggering 256 MB cache and the TDP would only be 225 Watt.
The new Epyc chip was tested against the previous top model of AMD, the Epyc 7601, and two Intel Xeon CPUs. Both single processors and dual-socket setups have been included in the results. A set-up with two Epyc 7742s has also been tested with an 'RDY1001C' suffix, but what exactly this means is unknown.

So the roamers were correct- Google is ditching Intel and going for ROME, also as google spokesman sad- Google can use the massive 128 lanes of PCIeGen4 for their accelerators- this is important for them, plus the EPYC 7742 competitor is XEON 8280M and not the regular 8280 since Epyc support upto 4TB of ram vs 2TB on 8280M and 1TB on 8280.
For this Extra 1TB ram support- Intel charged 30% more over the regular Xeon 8280.

"Many cores, bigger caches, more memory bandwidth, and a newer microarchitecture all help AMD quite a bit here. Intel asked us to compare a similar number of cores to be fair to their chips. In that spirit, the dual AMD EPYC 7502 configuration has 32 cores each while the dual Intel Xeon Platinum 8280 only has 28 cores each. AMD does not have 28 core SKUs.

On the other hand, the dual AMD EPYC 7502 is faster and uses $2600 each list price SKUs while the Intel Xeon Platinum 8280 is a $10,007 list price SKU. AMD provides four more cores per socket which help performance, but they are doing so at an initial list price discount of around 74%. That is a big deal if you assume Intel Xeon Platinum list pricing is designed so server vendors can utilize large 60% discounts. AMD still has the better platform, but we think here the Xeon Platinum 8280 can be very competitive with an 80% discount off of list price."

Ok Intel no problem, do you have any other desires?

"to be fair"

lol

same core count but same cost too, and then we can talk.....otherwise, deal with it!

If I'm not mistaken AMD made deals with Google and Twitter which'll help their bottom line.

Found it
