Blacksmith – Rowhammer bit flips on all DRAM devices today despite mitigations
Eventually, it will be obvious that running shared workloads on a single piece of physical hardware has fundamentally unremediatable security implications. This slow recognition is deeply perpendicular with how the current landscape of x86 chips are both manufactured and priced, as well as how cloud providers have structured billions of dollars in DC investment; in other words, they'll down-play it. This will be a massive opportunity for ARM & SoC manufacturers in the coming years, as its far better positioned to offer, for example, a single rack appliance with 64 individual 2-core mini-computers at a price-point competitive with a 128 core x86 rack, as one computer.Computing moves in cycles:- 2000s: gigahertz race on each core- 2010s: increase core counts, multicore everything- 2020s: back to core-efficiency and increasing per-core performance. M1 is already leading this charge, but is obviously a mismatch for a DC environment.AMD and Intel need to adjust, or face extinction. Its not just about pushing ultra-high per-core performance (they're both good at this); its about pushing for more efficiency, so per-blade density in a DC can be pushed higher in the face of more, smaller individual computers. If they don't evolve, AWS will for them [1].[1] https://aws.amazon.com/ec2/graviton/
