Once mitigations for Spectre, Meltdown, and whatnot are enabled, is hyper threading still a real gain?

- sidkshatriya 5y agoNewer generation Intel CPUs deal with some of these issues on a hardware level. See https://www.intel.com/content/www/us/en/developer/topic-technology/software-security-guidance/processors-affected-consolidated-product-cpu-model.html https://www.intel.com/content/www/us/en/developer/topic-tech... So the level at which your Intel CPU is "crippled" would depend on how old it is, I guess.
- goldenkey 5y agoAre these hardware fixes just bandaids or are the actual architectural flaws really fixed? Because didn't other processors that did speculative execution besides Intel's also have similar vulnerabilities? A lot of expert level folks on here were saying that the architecture surrounding speculative execution would need a total removal or reengineering to fix it.
