Intel was tilting at the internet rumor mill this morning as word circulated that its newly-launched Core i7 chips suffer from a technical glitch similar to the one that previously dogged AMD’s Phenom and Opteron cores.
A recent Core i7 software programmer’s manual update seems to indicate the chips have some Translation Lookaside Buffer-related issues. But Intel says it isn’t so.
From the document in question:
“In rare instances, improper TLB invalidation may result in unpredictable system behavior, such as system hangs or incorrect data. Developers of operating systems should take this documentation into account when designing TLB invalidation algorithms. For the processors affected, Intel has provided a recommended update to system and BIOS vendors to incorporate into their BIOS to resolve this issue.”
