Intel didn't support hyperthreading, which meant they wouldn't have matched AMD's performance in that area.

The announcement might have shown strong rivalry between AMD and Intel, though Intel could still excel in gaming with sufficient cores and threads. Their decision likely stemmed from various factors, not just thermal concerns. Most modern CPUs manage to stay below 80°C even during heavy workloads.
When discussing CPUs without this technology, it's mainly about targeting a specific market niche. Otherwise, HyperThreading or broadly known as simultaneous multithreading (SMT) works inconsistently—there are hardly any scenarios where SMT significantly boosts speed and in others it could actually slow things down.
yeah but all the amd fans keep saying intel doesn't have smt, atleast they would be on the spec sheet, on par with AMD
AMD cooling solutions might not grasp the concept of HyperThreading as Intel's version of SMT. In reality, situations where SMT performs well are rare, so turning it on or off usually doesn't make much difference. Security flaws discovered in chips aren't related to SMT; they pertain to speculative execution—a key part of today's processors.
Intel chips often contain various flaws connected to hyperthreading, including meltdowns and Spectre vulnerabilities. For instance, a flaw might let an app on one core quietly gather data from other cores or threads—something systems usually prevent. This could mean the app silently steals passwords or database details. Manufacturers released patches via BIOS updates and OS upgrades, but these changes typically reduce performance slightly. Instead of redesigning hardware or rewriting code, some newer models simply turn off hyperthreading to address these issues.
HyperThreading problems stem from SMT challenges, distinct from speculative execution concerns behind Meltdown and Spectre attacks. These vulnerabilities aren't exclusive to Intel; similar issues exist across other processors. Additionally, Meltdown and Spectre are not limited to Intel designs.
