AMD Phenom II X6 1055T review
Remember when AMD launched its first quad-core processor in 2007? We can, because back then it seemed like AMD was months from keeling over stone dead. Today, the company is in much finer fettle. For proof, look no further than the new AMD Phenom II X6 1055T.Somehow, AMD has managed to produce a six-core PC processor and sell it for just over £10 more than its best quad-core chip, the Phenom II X4 965 Black Edition. It's actually cheaper than several Intel quads. Inspect the detail specifications and the Phenom II X6 1055T only gets more impressive.The transistor count has grown from 758 million transistors to 904 million. And yet the smaller quad-core 965 is rated at 140 Watts while this new six-core 1055T is a 125 Watt chip. Of course, at 2.8GHz, the 1055T is clocked quite a bit lower than the 3.4GHz 965 BE. But AMD has clearly done something right. It's been a long time coming. But AMD finally has something really interesting to offer in the performance PC processor market. The new Phenom II X6 1055T gives you six cores for the price of four.
AMD Phenom II X6 1090T & 1055T
You’ll have noticed in the list of processors that AMD’s new 6-cores have a technology AMD call Turbo CORE. A real response to Intel’s Turbo Boost, this AMD technology works automatically like Intel’s, without any need for software or drivers: the only requirement is a compatible motherboard, which means all AM3 cards, as well as some AM2+ cards. In practice, when 3 or more cores become inactive, the clock of the active cores will go up by 400 or even 500 MHz depending on the CPU and within TDP limits. What about voltages? With the AMD OverDrive utility we were able to observe that these can vary. Thus, on our test Phenom II X4 1090T, when the Turbo got up to 3.5 GHz on some cores, voltages remained at 1.3V, but went up to 1.475V when the Turbo maxed out at 3.6 GHz. Not all motherboard bios’ necessarily allow you to disable the Turbo Core function, as is the case with the Crosshair IV Formula with its 0602, but the AMD OverDrive utility does offer this option. Better still, it also allows you to modify it precisely: number of cores, maximum multiplyer and VID. Here are a few screenshots in TMonitor showing the impact of Turbo CORE with Prime95, loading 1, 2, 3 and 4 cores successively.
AMD Phenom II X6 1090T BE & Phenom II X6 1055T Review
Although today AMD is announcing just two new processors, rumor has it we can expect a few more new models in the coming months. The Phenom II X6 1090T BE and 1055T processors are based on the architecture codenamed “Thuban” that uses the 45nm design process. Also slated for release are the Phenom II X6 1035T and 1075T processors that will operate at 2.6GHz and 3.0GHz, respectively. Meanwhile today’s release comprises of the Phenom II X6 1090T BE and 1055T processors that work at 3.2GHz and 2.8GHz. All the Thuban processors feature the traditional Phenom II 6MB L3 cache, while each individual core receives its own 512KB L2 cache . Compared to the Phenom II X4 processors that boast a total cache of 8MBs, the newer X6 models carry a total of 9MBs. Unlike the much more expensive Core i7 980X, AMD's six-core processors have not made the move to 32nm, as mentioned earlier they are still 45nm parts. Despite this AMD has specified a moderate TDP rating of 125 watts, even when operating at 3.2GHz. The Phenom II X6 processors support all the same features as the previous Phenom II X4 models with the addition of one new feature called Turbo Core. This hardware-based C-state performance boost technology is AMD’s equivalent of Intel Turbo Boost.
