AMD Phenom II X6 1055T and 1090T: More Cores, Less Price

Voltage Change

• AMD Phenom II X6 1050T (286×15, 1.4 V)
  
  

  Increasing the voltage to 1,4 V gave us more overclocking headroom. We successfully bumped the speed up to 4004 MHz.

• AMD Phenom II X6 1090T BE (200×21, 1.5 V)Too bad the 1090T BE did not fare that much better this time, as it only reached 4118,4 MHz, even with the voltage increase. It looks like our HSF has finally reached its limit.

Test Results

SYSmark 2007

Even with its fewer threads, our simulated “Phenom II X4 965” managed to score a preview rating higher than those of the 1055T and the 1090T BE. This benchmarking suite cannot fully utilize the extra cores of the Thuban-based CPUs. Most of the applications included in this benchmarking suite are more affected by clockspeed, rather than the amount of available threads.
