一名資深分析師表示，AMD能夠推出新款A(yù)-series芯片，可能表明這種代號(hào)為L(zhǎng)lano的32納米芯片的短缺狀態(tài)已經(jīng)結(jié)束。但AMD與英特爾競(jìng)爭(zhēng)態(tài)勢(shì)的較大轉(zhuǎn)變將出現(xiàn)在2012年，屆時(shí)這兩家廠商都將推出其下一代產(chǎn)品。 “這款新器件基本上是減速塊。AMD能夠出貨速度更快的A-series型號(hào)，我認(rèn)為這表明他們可能能夠改善供應(yīng)情況，” Insight64(美國(guó)加州)的首席分析師Nathan Brookwood表示，“由于產(chǎn)量有限，Newegg和亞馬遜等零售商根本搞不到早期版本的該款芯片?！? AMD與英特爾的競(jìng)爭(zhēng)態(tài)勢(shì)保持不變。 “在給定的價(jià)格水平，任何關(guān)注x86性能的人都可能看出來(lái)，英特爾Sandy Bridge CPU內(nèi)核的性能強(qiáng)于AMD Llano內(nèi)核，后者是K10內(nèi)核。K10內(nèi)核10年來(lái)一直是AMD的主力?！? 但是，“在圖形方面，二者幾乎不能相提并論，”因?yàn)锳MD的集成Radeon顯卡優(yōu)于英特爾Sandy Bridge GPU內(nèi)核。此外，AMD可以把它的嵌入與分立Radeon內(nèi)核連接起來(lái)以增強(qiáng)性能，而英特爾則無(wú)法利用Nvidia顯卡來(lái)做到這點(diǎn)。 在2012年的下一回合競(jìng)爭(zhēng)中，上述情況可能發(fā)生變化。明年英特爾將推出圖形性能得到改善的Ivy Bridge處理器，而AMD將推出Trinity芯片。Trinity芯片將搭載代號(hào)為Pile Driver的升級(jí)版Bulldozer CPU。 以前，英特爾總是在1月舉行的消費(fèi)電子展上推出其下一代處理器的首款臺(tái)式機(jī)版本。Brookwood認(rèn)為今年不會(huì)這樣。 Ivy Bridge的發(fā)布“可能推遲大半個(gè)季度”，他說(shuō)，“我不確定，這種22納米制程是否沒(méi)完全準(zhǔn)備就緒，還是芯片組沒(méi)有準(zhǔn)備好，因?yàn)樗麄冃枰状?支持) PCI Express Gen 3和USB 3.0”。 至于AMD的Trinity，“傳言稱(chēng)其準(zhǔn)備得相當(dāng)充分，AMD應(yīng)該在2012年初開(kāi)始投產(chǎn)，” Brookwood說(shuō)道，“Trinity和Ivy Bridge可能在2012年大致相同的時(shí)間內(nèi)推出。” 編譯：Luffy Liu 本文授權(quán)編譯自EE Times，版權(quán)所有，謝絕轉(zhuǎn)載 參考英文原文：Analyst: Shortage may be over for AMD Llano, by Rick Merritt

{pagination} Analyst: Shortage may be over for AMD Llano Rick Merritt The fact that AMD was able to refresh its A-series line may indicate the shortages are over for the 32-nm parts also known as Llano. But a bigger shift in the battle between AMD and Intel will come in 2012 when the two roll out their next-generation offerings, said one top analyst. "The new parts are basically speed bumps, and I am taking the fact AMD can ship faster versions of A-series chips as an indicator they may be able to improve their availability," said Nathan Brookwood, principal of Insight64 (Saratoga, Calif.) "Retailers such as Newegg and Amazon couldn’t get their hands on early versions of the chips because they were so production constrained," he said. The competitive stance of AMD and archrival Intel remains unchanged. "Anyone focused on x86 performance at a given price point may find the Intel Sandy Bridge CPU cores outperform the AMD Llano cores which are the K10 cores that have been an AMD workhorse for a decade," said Brookwood. However, "in graphics, there's almost no comparison" because AMD's integrated Radeon parts surpass what Intel can offer with its Sandy Bridge GPU cores. In addition, AMD can link its embedded and discrete Radeon cores to bolster performance, something Intel cannot do using Nvidia parts. That all could change in the next iteration in 2012 as Intel rolls out Ivy Bridge processors with improved graphics and AMD rolls out Trinity parts with an upgraded version of its new Bulldozer CPU called Pile Driver. In the past, Intel rolled out the first desktop versions of its next-generation processors at the Consumer Electronics Show in January. Brookwood does not expect that this year. The Ivy Bridge release "is probably pushed off by the better part of a quarter," he said. "I'm not sure if it’s the 22-nm process technology is not quite ready or the chip sets are not ready because they require [support for] PCI Express Gen 3 and USB 3.0" for the first time, he said. As for AMD's Trinity, "the rumors are the design is pretty much baked, and AMD should have wafers going into the oven in early 2012," said Brookwood. "It's likely we could see Trinity and Ivy Bridge come out in similar time frame in 2012," he added.
