Amazon Announces Graviton2 SoC Along With New AWS Instances: 64-Core Arm With Large Performance Uplifts

The new Graviton2 SoC is a custom design by Amazon's own in-house silicon design teams and is a successor to the first-generation Graviton chip. The new chip quadruples the core count from 16 cores to 64 cores and employs Arm's newest Neoverse N1 cores. Amazon is using the highest performance configuration available, with 1MB L2 caches per core, with all 64 cores connected by a mesh fabric supporting 2TB/s aggregate bandwidth as well as integrating 32MB of L3 cache.

Amazon claims the new Graviton2 chip is[sic] can deliver up to 7x higher performance than the first generation based A1 instances in total across all cores, up to 2x the performance per core, and delivers memory access speed of up to 5x compared to its predecessor. The chip comes in at a massive 30B transistors on a 7nm manufacturing node - if Amazon is using similar high density libraries to mobile chips (they have no reason to use HPC libraries), then I estimate the chip to fall around 300-350mm² if I was forced to put out a figure.

The memory subsystem of the new chip is supported by 8 DDR4-3200 channels with support for hardware AES256 memory encryption. Peripherals of the system are supported by 64 PCIe4 lanes.

    What undocumented data collection features are baked into the silicon?

    These chips are running at Amazon... you don't even have physical access.

    1-Click with new and improved cyber blockchain AI, is now baked into the silicon. Every time you click your mouse, type on your keyboard, or tap on a mobile device, a portion of your money is transferred directly from your bank account or cryptowallet directly into Amazon's.

      Source? This is what I have been looking for but do not see it in TFA.
