六月時因為電腦被老人搶走，等不到土機逼得只好提前買腰斬廢棄龍王，沒超頻的ｗｉｎＲＡＲ測試也已經近３０００，看來土機效能還是要等製程再改進了．
廢棄龍王六核ｗｉｎＲＡＲ測試跑到７３％，算起來只用不到四核半，看土機的成績應該也是類似的窘境．
看家裏另一台四核ｗｉｎＲＡＲ測試跑８７％，不到三核半．
來翻翻八核會跑出怎樣的ｗｉｎＲＡＲ測試好了，看有沒機會啟動ＴｕｒｂｏＣｏｒｅ．．．

如果是等B3的話，最好不要有太多效能期待比較好~雖然"據說"改蠻多的∼
轉貼翻譯一下謠言好了

AMD FX – Series B3 revision is more than just a basic stepping:
I have direct knowledge of a possible B3 revision for the AMD FX line of CPUs. I cannot disclose performance projections at this time, but be assured AMDs processor division is working vigorously on a (B3) stepping revision with minor architectural tweaks. The base architecture will not be changed at this time.

大意：推土機B3版將會針對架構做些微的調整，基本架構不改

See Other thoughts below.
Cons: Slower than the Phenom II X6 CPUs in a Clock for clock review(s). B3 revision coming to resolve this issue among a few more.
Other Thoughts: Within the B3 stepping revision, expect minor tweaks to the following:
1) L1, L2 and L3 latencies
2) Cache Thrashing Issues
3) Modified Algorithms for Branch Prediction
4) Healthy Bump in Processor Frequency
5) Slight Frequency increase via NB Controller
6) “Total Intelligent Control” For example programs and applications should look at the module design approach and the ability for the processor to intelligently turn off and/or turn on specific cores that it believes is hindering performance for maximum performance. (May be for Socket FM2, not sure at this time).
7) Power will be improved but not my much. We will have to wait for Socket FM2 or a future B4 revision for the AM3+ platform for better power efficiency especially when Over-clocked.

1. L1/2/3 Cache 的延遲調整 (沒說是改善∼但不會改慢吧XD)
2. Cache Thrashing Issues
這個有點難解釋∼基本上就是你有一份常常被cache的資料∼被另外一份常常被cache
的資料蓋掉了，導致cache miss 你要再花上百個cycle把正確的資料從記憶體讀回來
(運氣不好的話會再hit page fault XD) 常見於shared cache，這是一個bug fix
3. 修改分支預測演算法
4. Healthy Bump in Processor Frequency 這個我不懂
5. North Bridge 時脈些許提升?!
6. Total Intelligent Control
大意:改善應用程式使用CPU核心數以達到最好的效能 (有可能再FM2 才有)
7. Power改善 (到B4 revision / FM2 才會看到更好的power效能~尤其是超頻時)
