You face a big issue there. Meltdown is a core architecture issue. It will take a long time to make a fix. Add to that the need for a completely new branch predictor (a notoriously hard design issue) and you're talking about a lot of time. Intel and AMD should already have next years designs done (AMD has said as much with Zen 2). You'll most likely be looking at late 2020 to early 2021 before the fixed architecture is thoroughly tested, taped out, and being produced in volume.
- koheripbal 9y agoSo are we saying that since nothing is getting fixed in that interim period, that AMD chips suffer much less performance impact due to their lesser exposure to the issue?
- plorkyeran 9y agoEven 2021 is overoptimistic. Typical turnaround for a major design change in a CPU is more like 5 years.
