AMD: TLB Bug Fixed, 45nm Processors Due to H2 2008

AMD chief executive officer Hector Ruiz today uncovered that the TLB (Translation Lookaside Buffer) bug in all Phenom and Barcelona quad-core processors has been fixed. According to Ruiz, the fixed B3 stepping CPUs are "running through the paces internally" at this time with engineering samples expected to be shipped to customers within "2 to 3 weeks". Volume production is scheduled to begin "later in the quarter" and first systems with the fixed processors should become available late in Q1, president Dirk Meyer said. Production volume of Barcelona and Phenom quad-core will be about double of the nearly 400,000 units that were manufactured during Q4, CFO Bob Rivet noted. As previously reported, the higher speed and triple-core Phenoms will be postponed for the end of the first and the beginning of the second quarter. Hector Ruiz also commented on the company’s 45nm progress. Ruiz said that AMD's first 45 nm Opterons have been produced and the company is targeting for H2 2008 roll out.Source: TG Daily

and the workaround is easily turned off in most bios's but if not i believe crystalcpu had an off for it
Then you'll experience some nice old hardlocks. Im sure thats a even trade. Performance for locks ups.

Yeah, but they could butcher 45 nm like they did with 65 nm and the x2s. Unless Amd kept 90 nm chip around for a good reason which isn't really that likely.
would call it butchered, it alwase takes every company 1 steping/revision to get the kinks out of their new prosess size, intel isnt imune to this, remmber the first intel 65nm chips, people called them the "presHOT" for a reasion, damn things make a space heater more then a computer.

i can go back farther even since im an amd user by default.

remmber the tbredA, first gen of its prosess size, hot and didnt clock worth a damn, tbred-b the 2nd run of that proc size overclocked like mad and ran cool.

first 90nm chips the winchester cores SUCKED BALLZ for overclocking, but the venice and other 2nd/3rd run chips overclocked VERY VERY well.

the diffrance is it takes amd longer to move from revision to revision less fab space after all.

now this issue with the current k10's is a bad bad fuckup, but they arent being hurt in the linux market where there is an easy kernal fix for it, they are still selling to linux server makers in good numbers and demand is quite brisk.

b3 chips as stated fix the problems for windows users(most of us), i was in no huge rush to get a k10 anyway, wana see prices on tri and dual core units, quadcores really pointless for 99% of the home users out there.

Fixed at last though we've to see how much the bug-fix actually impacts performance. DaMulta put a Phenom 9500 to an acid test, he reports never to have observed anything weird.
I think its so many out of a batch that have the problems, course his board probably has the TLB patch in the bios for it.

l...again $ vs performance ratio is tilted toward humble little AMD....
Unless you overclock. Then Intel pulls ahead again.

I have to admit a E2140 at 3.2ghz beat out X2 cpus pretty amazingly. (Same thing with the E2160, E2180, E2200.

Which is all found for $95 and below depending on which chip you purchase.
But then you could argue that not everyone overclocks. But then you could argue that this is completely off topic.
