Closer Look at Phenom X3 8750

Triple-core Phenom X3 8750 looks exactly like its quad-core counterparts. Only the marking gives it away: HD8750WCJ3BGH.

While the first number “9” in the model name indicates Phenom X4, AMD selected indexes starting with “8” for its triple-core processors. “50” in the end of the marking stands for the absence of the TLB bus, jus like in Phenom X4, i.e. it means that the CPU belongs to B3 stepping.  The second digit depends on the frequency, and the principle here is the same for triple- and quad-core processors. In other words, Phenom X3 8750 you see on the photo above should work at 2.4GHz. It is the top model in the line-up today.

The CPU features three L2 caches (one per each core), each 512KB big and a shared 2MB L3 cache. The built in North Bridge works at 1.8GHz frequency and supports dual-channel DDR2 SDRAM that can work in Ganged or Unganged mode. So, the CPU uses 1800MHz HyperTransport 3.0 bus, however, nevertheless, it is compatible not only with Socket AM2+ but also with older Socket AM2 mainboards.

Nominal Vcore for Phenom X3 is set in the interval from 1.05V to 1.25V. Just like their elder brothers, these new processors support Cool’n’Quiet 2.0 power-saving technology, which, however, is only available on Socket AM2+ mainboards.
