Quote:In a statement to AnandTech, Intel explained that the key difference between "Whiskey Lake" and "Coffee Lake" is silicon-level hardening against "Meltdown" variants 3 and 5. This isn't just a software-level mitigation part of the microcode, but a hardware fix that reduces the performance impact of the mitigation, compared to a software fix implemented via patched microcode. "Cascade Lake" will pack the most important hardware-level fixes, including "Spectre" variant 2 (aka branch target injection). Software-level fixes reduce performance by 3-10 percent, but a hardware-level fix is expected to impact performance "a lot less."
