AMD Phenom II X6 1100T Black Edition Review – overclocking performance

The AMD Phenom II X6 1100T Black Edition is AMD's new flagship processor, available at launch for $265 in the states and £225 inc vat in the UK. The 1090T will move down to a very modest $235/£200 price point to make way for the new model.

The 1110T is a socket AM3 processor clocked at 3.3ghz (3.7ghz via Turbo) and is manufactured using a 45nm process. It has a total of 9MB of cache, which breaks down into 6MB of shared L3 Cache and 3MB of L2 cache, 512kb per core. Memory support is unchanged, with DDR2 up to 1066mhz and DDR3 up to 1333mhz being offered. Obviously you can run faster than this via the motherboard bios, but these are the conservative ‘official' specifications direct from AMD.

These official specifications deliver up to 17.1 GB/s memory bandwidth with DDR2-1066mhz and 21.3 GB/s memory bandwidth with DDR3-1333mhz.

The processor runs via the Hypertransport 3.0 bus at up to 4,000 MT/s full duplex (2.0ghz x2). This particular processor is rated to a maximum TDP of 125 watts and a maximum temperature threshold of 62c. The AMD official rating for the voltage is set between 1.125 v and 1.40 volts – although we will delve into this more later.

As before, while the processor is rated to 3.3ghz, under Turbo it can achieve 3.7ghz. This means that when the processor isn't needing the full power of all six cores, it can shut down half the cores and increase the clock speed to a maximum of 3.7ghz. Most overclockers disable this feature then force all cores to achieve higher speeds anyway, and this is exactly what we will be doing later.

The physical appearance of the 1100T is just like any other Phenom II processor we have looked at.
