何謂勁何謂唔勁？自己用唔到就唔勁？咁世界 top500 果D 超級電腦咪屎到爆？佢地跑 3Dmark 隨時慢過Pentium  ...

問題係 你同頻慢過上代 U 呢下先死呢

APU Bobcat, 衰衰地 慢過上代 但係 "on target" (其實AMD 都係話 8~9成 K8 )
慳電做好左

Bulldozer ?
1. 依家見到既係, 熱又熱左, 要一體式水冷先頂得順 (WTF?)
2. 同頻慢過上代U , 都唔好話用 Sandy Bridge 黎比, 拿翻 Deneb , 我頂你 重慢過 Deneb
你出黎把託咩

整粒 Phenom II X8 / Phenom III 好過整部拖拉機

我下部機都轉intel了

肥龍一代 我都算
你再整多鑊重衰過肥龍一代既野出黎

重好意思話 Eight Core ,
慢過人 , 重要掛 FX 個名 影衰晒當年 Athlon64 FX !!!!

Just update from XS

"Actually, we already have such an issue known for Bulldozer, and NO bench-marked system has the patch installed!

The shared L1 cache is causing cross invalidations across threads so that the prefetch data is incorrect in too many cases and data must be fetched again. The fix is a "simple" memory alignment and (possible)tagging system in the kernel of Windows/Linux.

I reviewed the code for the Linux patch and was astonished by just how little I know of the Linux kernel... lol! In any event, it could easily cost 10% in terms of single threaded performance, possibly more than double that in multi-threaded loads on the same module due to the increased contention and randomness of accesses.

Not sure if ordained reviewers have been given access to the MS patch, but I'd imagine (and hope) so! Last I saw, the Linux kernel patch was still being worked on by AMD (publicly) and Linus was showing some distaste for the method used to address the issue""

   

就係 Module 玩share L1 出事........要 OS 落patch 改 kernel  , 死未

人地i系輕鬆搞掂佢

Design Defect , 要 respin / redesign
所以 今代 Bulldozer 都係收皮了

untvb

delay 咁耐都未寫好個 patch ?
