We remember a time when journalists used to have at least a teacup-full of respect for AMD’s NDAs, but that now appears to have been poured down the sink too. The latest leak to hit AMD is the exposure of its desktop processor roadmap for the rest of this year, which confirms a lot of what we knew already, but also adds plenty more to the picture.
The roadmap was unashamedly published by VR-Zone, where you can find four presentation slides detailing the company’s forthcoming Phenom II X6 and X4 CPUs. Yes, it could be a fake, but we’ve seen plenty of AMD presentations in our time, and we’re 99 per cent sure this is genuine.
The first interesting feature confirmed by the roadmap is the presence of a new technology called TurboCore. This is AMD’s own equivalent of Intel’s TurboBoost technology, which hit the rumour mill back in February. According to the slides, TurboCore only kicks in when less than half of the available cores are active, but it then really pushes up the clock speed by up to 500MHz.
The slides also reveal that there are more Phenom II X6 models than we first thought. Previous information indicated that the Phenom II X6 1075T would be at the top of the pile, but this latest leak shows a new king of the six-core stack.
The Phenom II X6 1090T will apparently be clocked at 3.2GHz, but will then climb up to 3.6GHz when TurboCore kicks in. Meanwhile, the 1075T is clocked at 3GHz (3.5GHz with TurboCore), while the 1055T is clocked at 2.8GHz (3.3GHz with TurboCore) and the 1035T is clocked at 2.6GHz (3.1GHz with TurboCore).
Interestingly, two versions of the 1055T are listed – one with a TDP of 125W, and one with a TDP of 95W. The specs are otherwise the same, so it will be interesting to see what AMD has done to reduce the power. It’s certainly not a die-shrink, as another slide says that all of the new X6 CPUs are based on the 45nm SOI (silicon-on-insulator) “Thuban” core.
As with AMD’s current line-up of AM3 CPUs, the slides say that all of the CPUs are also compatible with AMD’s older AM2+ motherboards, although they’ll need to be equipped with DDR3 memory slots to be compatible with the integrated memory controller. According to the slides, the CPUs will support DDR3 memory clocked at up to 1,333MHz (PC3-10666).
Finally, there’s also further confirmation of AMD’s new quad-core Phenom II X4 690T, which may well be able to be unlocked and turned into a six-core chip.
According to the slides, all of the X6 chips are scheduled for production in April this year, with the exception of the 1075T, which is scheduled for production in the third quarter of 2010.
