AWS Graviton2 ARM cloud server review video

Hi all.
I’ve reviewed the Amazon AWS Graviton2 ARM server.
It has an amazing SoC with 64-cores ARM N1 at 2.5Ghz.
This may not sound such a high clockspeed. But it outperforms anything else per clock.
I’ve recently also reviewed the Threadripper 3990x and the Ampere 32-core ARM64 server. I compare the performance of these with the Graviton2.

Since I can’t share a link you can find my video on youtube, channel name is NicoD’s SBCs.

I normally review ARM single board computers. But had a blast with these servers. So I might do more server reviews.
I’m not a professional reviewer like Wendell. And don’t nearly have his knowledge. But I love to nerd out on cool tech.

Here some of my gathered info, a lot more in the video.
AWS Server 32-cores 128GB

NEOVERSE N1 64-core AWS Graviton2
ARMv8.2 aarch64
Arm’s Neoverse N1 cores -> based on A76 -> almost identical to Arm’s 64-core reference N1 platform -> CPU cores are clocked a bit lower 2.5GHz and only 32MB instead of 64MB of L3 cache
Max speed 2500Mhz
8-channel DDR-3200
128GB ram
64 PCIe4 lanes
TSMC’s 7nm process node
~1W per core at the 2.5GHz frequency
between 80W as a low estimate to around 110W estimation. This info is not disclosed by AWS

CPU Miner
Odroid N2+ : 14
Ampere 32-core : 87
AWS Server 32-core : 154.20
ThreadRipper 3990x : 1310

Internet speed test between 1500 Mbit/s and 2000 Mbit/s both up- and download (up to 250MB/s)

I had 32-cores of the 64-cores. It is expected to perform a bit worse per core with 64-cores vs 32-cores since less cache available per core.

There’s a newer Ampere 80-core N1 at 3Ghz SoC.

Greetings, NicoD


Wow, this is sweet info!

So it seems like those N1 cores are seriously good performers.

Hey NicoD, welcome to he forvms. I saw your video and meant to suggest that you post over here for a conversation starter. Thanks for your work.
