This result attained by Intel's dual-core processor is particularly attributable to hyperthreading (HT) - the division of the two cores into four virtual CPU units. This was underscored by the fact that when the HT function was turned off, the tables turned and the AMD Athlon 64 X2 4800+ surpassed its rival. Here, it is impossible to speak in terms of percentages, precisely because of the different load distributions.
We got a different picture, however, when we ran single applications on each system. Here, the AMD system performed distinctly better (by just about 30% on average) compared to the Intel system.
Thus, when making a purchasing decision, the question to ask is whether or not multiple applications will be running simultaneously. If the answer is yes, then the Intel Pentium 840 EE is your first choice. Otherwise, the AMD Athlon 64 X2 4800+ will give you much better performance for single applications.

Về ổn định, trên Tom's HWG có nói là chỉ bị lỗi khi chạy với chipset nForce SLI mà, còn chạy tốt với chipset của Intel (2 tuần không có một lỗi nào!)
Kết luận là AMD chạy tốt với nForce SLI nhưng vẫn có lỗi (sau 1 giờ thì hệ thống không tắt được bằng phần mềm).

However, in exchange, the user does gain the benefit of stability - our Intel system ran for 14 days without a problem. The AMD system ran smoothly from the start, which leads us to conclude that the nForce SLI basis is stable with the AMD platform. The only downside was that after long periods of operation, the AMD machine wouldn't shut down via software.
Kết luận là:
D 840 kém hơn 840 EE vì không có HT
