in Unreal Engine games, but a small step toward a solution has been made, with the discovery in the code that controls how the boost clock is managed. Gamers hoping for a total fix will need to wait, though, as Intel says that the bug isn't the root cause of the CPU instability., citing an internal Intel document on a microcode error that affected the eTVB feature of Core i9 processors.

While using the default limits greatly helps to prevent Core i7 and i9 processors from becoming too hot and unstable, they also impact the maximum sustained performance of the chip. Where a CPU might be able easily to reach 5.6 GHz at 250 W, it will only briefly do so and not sustain it at, say, 150 W or lower.

Where it does become an issue is in applications that load up all the cores for sustained periods, such as offline renderers and large-scale data processing. The former is typically used in showcasing the performance of a new CPU, usually in the form of
