Microsoft leak reveals hotfix for underperforming Bulldozers
AMD's Bulldozer silicon is enormously powerful, but most software isn't configured to schedule threads for the faux-16 core design. Windows can only see the chip as a quad-core CPU and will randomly assign threads, which ruins the point of Bulldozer's "Turbo Core" design. Microsoft inadvertently revealed it had teamed up with the chipmaker to fix the problem when it prematurely released a hotfix for Windows 7 and Windows Server 2008 R2. Initial tests showed that it could improve performance by up to seven percent, before it was pulled -- Microsoft conceding that it wasn't quite ready for prime-time.
AMD ships 16-core Bulldozer chips for servers, makes consumers wait their turn
AMD's Interlagos, its server-styled Bulldozer chip -- Mr. Opteron 6200 to you and me -- is being pushed out to retailers and OEMs ready for an October launch. AMD is calling it the first 16-core x86 processor, although as we know from the required reading, it has eight two-core shared modules rather than 16 independent ones. The chips are compatible with Socket G34 motherboards, but most of this first production run will go straight into supercomputer projects. AMD remains mute on progress of the consumer-level Zambezi, but rumors are that the company can't clock it fast enough to compete with Intel's Core i7 -- the very class that Bulldozer was designed to bury.

More details emerge on AMDs Bulldozer for high-end desktops
AMDs Bulldozer is the company's anticipated high-power rival to Intel's Core i7 and the company just released a slew of new information about its internals. Now, pay attention 007 -- the "Zambezi for Socket AM3+" chips will include four modules, each with two cores and 2MB of L2 cache. Operating above these is a single Northbridge with 8MB of L3 cache to direct data between two 72-bit DDR3 channels and 4 x 16-bit receive / transmit HyperTransport links. Finally, the "Turbo Core" increases the whole chip's click speed when taxed or kills power to idle cores when it's not. Hustle on down to the source link to see the slides yourself.

AMD's 3.2GHz hexacore Phenom II X6 1090T comes out for a review roundup
How's your memory today? Specifically, can you remember the last time AMD had a legitimate claim to the desktop performance crown? Don't hold your breath, the latest and greatest Phenom II still can't steal the spotlight from Intel's spectacular top-of-the-line Core i7-980X, but if prices actually matter to you, you'll wanna read on. Whereas you'd need to shell out $999 to get six cores from Intel, AMD is offering you its flagship 3.2GHz 1090T model at a reasonable $285, or an even more affordable option with the 2.8GHz 1055T at $199. The T in those names stands for Turbo Core, which automatically downclocks half the cores in order to provide a little extra speed (up to 500MHz more) to the other three. Reviewers agreed that its inclusion helped significantly improve single-threaded performance, to the point where the faster (in default clock speed) 3.4GHz Phenom II X4 965 was falling behind in benchmarks. The general opinion by the typically jaded journalists was that AMD has finally regained some pep in its step and that these new 6-core CPUs are going to give Intel's upper midrange offerings something to worry about. Lest we forget, the 1090T and 1055T also retain socket compatibility with current AM2+ and AM3 motherboards, making upgrades a cinch too. The full reviews await below.

AMD's hexacore Phenom II X6 will offer Turbo Core automatic overclocking
AMD might be playing catch-up with Intel at the moment, but at least it's keeping the distance fairly close. Intel has yet to fully transition its desktop line over to its Turbo Boost-boasting Core 2010 series, yet its competitor has already announced its own, imaginatively titled, competing technology in the form of Turbo Core. It's a less sophisticated auto-overclock, whereby three of the six cores are decelerated in order to give the other trio some extra voltage and speed for more serialized workloads. The truly impressive thing is that operation under the Turbo Core mode and the default hexacore arrangement will fit within the same power envelope as current Phenom II X4 CPUs, while AMD also reassures its loyal users that the new Phenom II X6s will be compatible with existing AM3 and AM2+ sockets. Nice. The table above, provided by AnandTech, confirms the models we heard about a couple of weeks ago, though we'll have to wait a little bit longer to get confirmation on pricing.
