那個價格買水冷不知道划不划算?

那個水冷是一體式的KÜHLER H2O 920
網拍售價NT$3990

水冷盒裝價 大概就是FX-8150、KÜHLER H2O 920,
就日本報價看是這兩個價格直接加在一起

台灣售價一萬多個兩三千 大概是跑不了(不過這也要買的到才行)

AMD Spreads Propaganda, Ex-Employee Speaks OutWritten by Sam (Insideris) on October 13, 2011

Launches a man with a shovel.
Back in old days, AMD has issued fake Barcelona CPU benchmark results to lure in some buyers. As we know, it did not turn out well for them.
Well, few years later and the history repeats itself, just check this AMD FX promotional video below:


Now, we did some digging and found out quite few interesting things. Here is a quote from the AMD ex employee himself, who posted few comments about the whole situation some time ago:

On paper bulldozer is a lovely chip. Bulldozer was on the drawing board (people were even working on it) even back when I was there. All I can say is that by the time you see silicon for sale, it will be a lot less impressive, both in its own terms and when compared to what Intel will be offering. (Because I have no faith AMD knows how to actually design chips anymore). I don’t really want to reveal what I know about Bulldozer from my time at AMD.

What did happen is that management decided there SHOULD BE such cross-engineering ,which meant we had to stop hand-crafting our CPU designs and switch to an SoC design style. This results in giving up a lot of performance, chip area, and efficiency. The reason DEC Alphas were always much faster than anything else is they designed each transistor by hand. Intel and AMD had always done so at least for the critical parts of the chip. That changed before I left – they started to rely on synthesis tools, automatic place and route tools, etc. I had been in charge of our design flow in the years before I left, and I had tested these tools by asking the companies who sold them to design blocks (adders, multipliers, etc.) using their tools. I let them take as long as they wanted. They always came back to me with designs that were 20% bigger, and 20% slower than our hand-crafted designs, and which suffered from electromigration and other problems.
That is now how AMD designs chips. I’m sure it will turn out well for them [/sarcasm]

BTW, you ask how AMD could have competed? Well, for one thing, the could have leveraged K8 and the K8 team’s success and design techniques instead of wasting years of time on a project that eventually got cancelled using people that had never achieved any success. It took Intel years to come out with Nehalem, and AMD could have been so far ahead by that point that they’d have enough money in the bank that they wouldn’t have to accept a low-ball settlement offer in the antitrust suit and they wouldn’t have to sell off their fabs.

Gives a totally different perspective on why Bulldozer failed, doesn’t?
Stay tuned.

官方會說這是離職員工心懷不滿的報復言論啊
可是這些說法很可以解釋推土機效能低耗電量高
反正就是大頭做了一個錯誤的決定
仿照soc的作法,買一些明明比較差的方案來兜
結果推土機根本就是設計不良

最不該縮減單執行緒效能
當年p4低落單執行緒效能AMD大概忘了
把低效能的單執行緒組合起來,單核還是大敗,要是軟體沒支援那麼多執行緒....效能就會大砍

為了解決頻寬問題

下一代將不用DDRX的記憶體改用Rambus XDR2


這不是拿老劇本重拍嗎?

沒有強人,沒有老手,Amd難以再塑K8初現時的風光
公司所謂的技術其實不是掌握在『公司』的名號,而
是關鍵的幾個核心技術人才,那些人一旦跑掉了,就只
看到Amd在K8之後原地踏步,K10,K10.5幾乎承繼
了K8的血統,微縮製程和核心微調已到極限,花了五年
弄出的BD在紙面上所向披靡,還冠上FX的頭銜,靠著
行銷手法吹噓乎弄,最後上了檯面的東西竟然是這樣?

現在的問題是,AMD內部還有人知道怎樣做出像樣的
東西嗎?他們在intel的競爭之下非但不能拉近差距,
還被越拉越遠,甚至連超越垂垂老矣的舊架構都充滿疑
問,明年的BD II再不行,那就別奢望AMD還能重回高
階desktop的競爭吧

amd k7-->k8
做出來的變革與創新另人刮目相看,但自從core 2出來之後,amd好像就開始挨打,到現在好像有點挨打到習慣了
沒辦法,科技產業技術不如人、產量不如人、資金不如人是很難拼過老I,但你總要用另一種方法打出一片血路吧,就像k7/k8時代那樣,給大家一種很驚豔的感覺..
從core 2/i7一出,好吧灰姑娘到了晚上12點,夢該醒了,馬車變回南瓜,我們消費者是現實的,總不可能佛心買一個CP值低的慘品。
我們不可能喜歡amd從此不振,也不喜歡CPU只能選擇一樣菜,希望amd好好加油,至少推土機二代可以像龍二哥一樣,讓消費者覺得不錯,再加上開核噱頭
我以往也買了amd k6、k7、k8、P2,但最近真的沒有想買amd cpu產品的念頭,顯示卡倒是買了兩張6870,我不看產品的牌子,只看好用不好用,多加油吧,amd。

AMD一開始(2007年)就是朝這個方向前進(朝效率 而不是效能,會往八核心發展)
而且也知道弄出來的Die會很大顆
也就是說他們早就知道這些東西,而且是刻意往這個方向做
http://pc.watch.impress.co.jp/docs/...7/kaigai376.htm

就現在而言大部分AMD想做的事都達成了
只是最重要的那個performance per-watt 原本目標是K10 1.3倍以上
最後成品卻是0.824倍 XD
(是決策還是製程問題只有AMD跟GF 自己知道)

> 為了解決頻寬問題

> 這不是拿老劇本重拍嗎?
看來是支援(音:反串)過了頭,有頻寬問題的是APU
就推土機純CPU來講頻寬影響不大 (已經有測試顯示這點了)
就純GPU來講,嗯...(這這個分區不是在講純GPU的吧 略)
--
題外話
糟的是AMD又說了APU的頻寬問題要等到下一世代GPU出來才能解決
(推土機2009年公佈時AMD就說很爛但沒人相信
現在AMD又說APU有頻寬有問題 這次應該會有比較多人相信了吧?)

沒解決頻寬明年APU圖形運算效能的 頂多就是比現在的 強一咪咪
然後搭配上Pile Driver 想到就 XD

就說AMD總是喜歡把Server的東西套用到DT上
Server的東西又不見得適合DT,你整個套用下來,有些不適合DT的部分就會跟著延續下來,要不然就得重新設計

只能說越作越差,推土機本身理念不錯,但是給AMD作出來感覺就是特別差。製程落後,整個核心架構效率又不太好,就算想作另類的P4也不是這樣的做法吧!DT的單線程越作越倒退,那就算了,看到最低3.1G起跳,最高3.6G,我就覺得不用玩了....跟當初預估4G起跳真的差太多,要不然你也3.6G起跳,這樣就夠慘了,還3.1G....感覺好像吃東西想硬吞結果吞不下去噎到了一樣。真搞不懂,一大堆測試軟體可以測試,作出來不會試試看性能如何嗎?車子作出來不會試跑一下嗎?還是說東西會動就好了,其它跑的快不快順不順不重要,東西只要跟以往的看起來有差別就好了....

東西都出來了,這種表現你還能夠說什麼呢?如果以這個結果來說,絕對有非常大的改良空間,很可惜的是改良者的不是Intel,而是AMD,光是這一點就不敢抱什麼期待了。所以Trinity....我看還是算了,老本總有一天會吃光的,真同情ATI,居然會搭到這樣的CPU,真的是欲哭無淚....
