Just like this CPU but with a different OPN (CW at the end, rather than CN). This particular CPU has been manufactured a year later (35th week of 2007). In that time-frame it was considered a budget CPU; especially because this CPU is single-core and most new regular/high-end systems shipped with dual-core CPU's. > Read more
High-end single-core at it's end. Both the Athlon 64 3800+ and 4000+ run at 2400MHz with the latter having extra 512KB L2-cache. In 2006 people could choose between the Athlon 64 3800+ (2.4GHz) and the Athlon 64 X2 3800+ (2GHz). Applications and games specific for dual-core CPU's weren't around so many so a few people got the single-core version instead. the single-core version is faster with single-threaded applications because it's clock frequency is higher compared to the dual-core version. > Read more
