An EPYC trip to Rome: AMD is Cloudflare's 10th-generation Edge server CPU

Intel 6162 @ $3115.00 x 2 = $6230

AMD EPYC 7642 [1] @$5,312.13

A recent model from 2019 would be Intel® Xeon® Gold 6262V Processor [2]. Which is the same 24 Core but Cascade Lake, lower TDP ( On Paper ) , and cost $2900, or $5800 for 48 Core.

So for roughly the same price you get 30% Request Per Watt Increase. Which is like the article suggest, lower than what I expected. May be one reason why AMD hasn't gained more market shares in Server.

Hopefully the next EPYC trip to Milan will be better than the trip to Icelake.

Edit: There is actually another article from CF on the EPYC performance. [3]

At the beginning of the month, I bought a single watercooling block for a Supermicro board that cools dual SP3 CPUs and the VRM. It's going into a virtualized workstation/server with half a TiB of RAM and dual entryish-level Romes (I'll buy new/used 7742's later).

If the Rome NDA roadmap compared to actual time is any guide, Milan will be out within the next few weeks. (I'm hoping for a price drop on Rome.)

I'm working on learning propane+oxy borosilicate glass bending & tempering and figuring out how to make a custom 14-port distro plate with dual D5's. Fusion 360, McMaster's and somewhere that has a 3-axis milling machine for rent maybe in my future.

EDIT: here's the rough specs, plus another ~$1400 for watercooling gear

I missed the power draw measurements if they did some, but normally AMD list their TDP as a maximum while Intel can push over their rated TDP.

They also didn't address Intel CPU shortage which maybe hasn't affected their server segment, but is the main reason why OEM are turning away from them.

I would like to see what CloudFlare's actual cost per CPU would be in a bulk order or through a vendor. They left off the cost aspect in this review though based on the numbers you list (and higher numbers on Intel's Ark site) it could be a factor though overall power usage probably outweighs cost per unit.
