NicoD Posted November 27, 2020 Posted November 27, 2020 Hi all. I've just finished a new video where I review an Amazon AWS Graviton2 arm64 server. This is a monster with 64 high-performance N1 cores. It isn't clocked that high at 2.5Ghz, but it performs amazing for that clockspeed. Here is my video. Here all the info I've gathered. 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 7z single core Ampere 32-core : 2763 AWS 32-core : 3393 Threadripper 3990x : 4545 7z quad core : Raspberry Pi 4 @ 1.5Ghz : 6307 Odroid N2+ 4xA73@2.4Ghz : 9900 Ampere 32-core : 11145 AWS 32-core : 13733 Threadripper 3990x : 18060 7z all cores : Ampere 32-core : 85975 AWS 32-core : 110628 Threadripper 3990x : 391809 433702 OC Blender BMW CPU Odroid N2+ : 30m Ampere 32-core : 8m27s AWS Server 32-core : 2m08s ThreadRipper 3990x : 30s Blender Barber shop CPU AWS Server 32-core : 8m28s Threadripper 3990x : 2m18s79 CPU Miner Odroid N2+ : 14 Ampere 32-core : 87 AWS Server 32-core : 154.20 ThreadRipper 3990x : 1310 SBC bench : http://ix.io/2FrG 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. https://www.anandtech.com/show/15578/cloud-clash-amazon-graviton2-arm-against-intel-and-amd/6 Thank you to @lanefu for giving me access to this. 2
