Compatibility

Information on Core 2 Duo T6400 and Core 2 Duo T5850 compatibility with other computer components: motherboard (look for socket type), power supply unit (look for power consumption) etc. Useful when planning a future computer configuration or upgrading an existing one. Note that power consumption of some processors can well exceed their nominal TDP, even without overclocking. Some can even double their declared thermals given that the motherboard allows to tune the CPU power parameters.

We believe that the nearest equivalent to Core 2 Duo T5850 from AMD is Athlon II P360, which is faster by 1% and higher by 4 positions in our rating.

Here are some closest AMD rivals to Core 2 Duo T5850:

Advantages of Intel Core 2 Duo T6400

Somewhat newer (1 January 2009 vs 1 October 2008)

Finer manufacturing process technology (45 vs 65 nm)

Intel 64 (64-bit Intel CPU architecture. Almost identical to AMD64, except small and rarely used nuances)

Advantages of Intel Core 2 Duo T5850

Cheaper ($9 vs $33)

Higher boost clock speed (2100 vs 2000 MHz)

Lower power consumption (34W vs 35W), meaning that the rival with higher TDP might require a better cooler or other thermal solution.
