Review on TLB bios patch
Phenom TLB patch benchmarked - The Tech Report - Page 1
Takes about a 14% performance hit overall, and in synthetic memory tests all the way up to 57%.

AMD's other major concern here should be for its reputation. The company really pulled a no-no by representing Phenom performance to the press (and thus to consumers) without fully explaining the TLB erratum and its performance ramifications at the time of the product's introduction.
As we've reported elsewhere, AMD does plan to fix the TLB erratum with a new revision of its quad-core chip due some time in mid-to-late Q1 of 2008. Once the new revision is available, the Phenom 9500 and 9600 will be replaced by the 9550 and 9650, with the -50 suffix denoting the updated silicon and higher performance. Most users will want to wait until those new Phenom models are available before paying full price for a Phenom processor or a system based on one |
And I've been thinking this for awhile, this TLB thing should have been spotted long before Phenom was presented publicly and certainly shows that AMD is not on top of things. Let's hope the new revision fixes everything.
