What the Phenom X3 8600 is

The AMD Phenom X3 8600 is a 2.3 GHz triple core from the first triple-core launch on March 27, 2008. It runs three K10 cores at 2.3 GHz with no turbo, so 3 cores give 3 threads. Cache is 512 KB of L2 per core under a shared 2 MB L3 on a 65 nm process. Power is rated at 95 W on Socket AM2+.

The 8600 is built on the older B2 stepping, part HD8600WCJ3BGD at 1.20 to 1.25 V, which carries the TLB erratum that the later B3 50-series triples fixed. Its HyperTransport link runs at 1.8 GHz. A business-class 8600B on the same B2 stepping followed for corporate buyers on April 28, 2008.

Socket and motherboard compatibility

The 8600 needs a Socket AM2+ board with DDR2 memory and a BIOS that recognizes first-generation Toliman parts. Boards may need the TLB erratum workaround BIOS for B2 steppings. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Memory, PCIe and cooling

Memory is DDR2-800 and DDR2-1066 in two channels.

HyperTransport 3.0 at 1.8 GHz links the CPU to the chipset. PCIe slots hang off the chipset.

Cooling should be rated for 95 W on the 48 x 96 mm mount, with Cool'n'Quiet trimming clocks and voltage at idle.

Upgrade paths

On Socket AM2+ the upgrade is the AMD Phenom X3 8650 at the same 2.3 GHz on the fixed B3 stepping, or the AMD Phenom X3 8750 at 2.4 GHz. The AMD Phenom X3 8400 is the slower B2 launch triple for collectors.

Frequently asked questions

What socket does the Phenom X3 8600 use?

Socket AM2+, the 940-pin package on DDR2 boards with HyperTransport 3.0.

How many cores does the Phenom X3 8600 have?

Three cores and 3 threads at 2.3 GHz with 512 KB of L2 per core plus 2 MB of shared L3.

What is the difference between the Phenom X3 8600 and 8650?

The 8600 is a B2 stepping with the TLB erratum; the 8650 is the same speed on the fixed B3 stepping.
