市場(chǎng)研究機(jī)構(gòu) IDC (International Data Corp.)日前調(diào)降對(duì) 2011年 PC 微處理器出貨量的成長(zhǎng)率預(yù)估，由原先的10.3%下修為9.3%；這意味著發(fā)達(dá)地區(qū)的經(jīng)濟(jì)問(wèn)題已經(jīng)對(duì)消費(fèi)性PC需求產(chǎn)生影響。 根據(jù)IDC的統(tǒng)計(jì)，2011年第二季 PC 微處理器出貨較第一季減少了3%，與2010年同期相較，成長(zhǎng)率則不到1%；在銷售金額方面，PC微處理器市場(chǎng)第二季營(yíng)收規(guī)模為94.9億美元，較第一季減少4%，與去年同月相較則成長(zhǎng)5%。 “2011年第一季的表現(xiàn)優(yōu)于之前大多數(shù)的第一季情況，是因?yàn)轭~外的日歷周(the extra calendar week)；”IDC半導(dǎo)體/個(gè)人計(jì)算機(jī)研究總監(jiān)Shane Rau表示：“因此第二季的季成長(zhǎng)率表現(xiàn)并不令人意外，如果把額外的周數(shù)去除，該市場(chǎng)第二季表現(xiàn)會(huì)呈現(xiàn)微幅季成長(zhǎng)的情形?！? IDC指出，由于英特爾(Intel)與 AMD 都陸續(xù)推出整合繪圖處理功能的新一代微處理器，第二季這類產(chǎn)品已經(jīng)占據(jù)整體PC微處理器出貨的六成以上；其中英特爾的整合型處理器市占率達(dá)到88%，但該數(shù)字在第一季為92.2%；至于AMD整合型處理器的第二季市占率，則由第一季的7.8%成長(zhǎng)為12%。 Intel與AMD在PC處理器市場(chǎng)的勢(shì)力消長(zhǎng) 英特爾在整體PC處理器的市場(chǎng)占有率，在第二季由第一季的80.8%縮水為79.3%；AMD的第二季市占率則略有成長(zhǎng)，從第一季的18.9%來(lái)到20.4%。至于在移動(dòng)PC處理器部分，英特爾第二季市占率為84.4%，較上一季的86.3%略減；AMD的移動(dòng)PC處理器市占率，則由第一季的13.4%，在第二季達(dá)到15.2%。 在臺(tái)式PC處理器部分，英特爾第二季市占率為70.9%，較第一季的72.4%略有退步；AMD臺(tái)式PC處理器的第二季市占率則為28.9%，該數(shù)字上一季為27.4%。在服務(wù)器與工作站處理器部分，英特爾的第二季市占率高達(dá)94.5%，上一季為93.3%；AMD在該市場(chǎng)僅有5.5%的占有率，較第一季的6.1%略為退步。 編譯：Judith Cheng 參考原文： IDC cuts PC microprocessor forecast，by Dylan McGrath

{pagination} IDC cuts PC microprocessor forecast Dylan McGrath International Data Corp. (IDC) Tuesday (Aug. 2) cut its forecast for 2011 PC microprocessor shipment growth to 9.3 percent from 10.3 percent, saying economic headwinds in developed regions that are affecting consumer PC demand. PC microprocessor shipments declined 3 percent in the second quarter compared with the first quarter and were up less than 1 percent compared to the second quarter of 2010, according to the latest PC microprocessor market share study from IDC. In terms of sales, the PC microprocessor market was worth $9.49 billion in the second quarter, down 4 percent compared to the first quarter and up 5 percent compared to the second quarter of 2010, IDC said. "The first quarter of 2011 was better than most first quarters due to the extra calendar week," said Shane Rau, director of semiconductors/personal computing research at IDC, in a statement. "So the sequential comparison isn't surprising. If we took off that extra week, the performance between the two quarters probably would've seen a seen a slight sequential uptick from 1Q to 2Q." Both Intel Corp. and Advanced Micro Devices Inc. (AMD) continue to ramp new microprocessors with integrated graphics processors, IDC noted. The firm said processors with integrated graphics accounted for more than 60 percent of total PC processor unit volume in the second quarter. Intel held 88 percent market share for processors with integrated graphics in the second quarter, down from 92.2 percent in the first quarter, while AMD's share for these types of devices grew to 12 percent from 7.8 percent, IDC said. Intel's share of the overall PC processor market declined to 79.3 percent, down from 80.8 percent in the first quarter, IDC said. AMD held 20.4 percent of the PC processor market in the second quarter, up from 18.9 percent in the first quarter, IDC said. Intel had 84.4 percent market share in mobile PC processors in the second quarter, down from 86.3 percent in the first quarter, IDC said. AMD held 15.2 percent share of the mobile PC processor market in the first quarter, up from 13.4 percent in the first quarter, according to IDC. Intel had 70.9 percent of the market for desktop PC processors in the second quarter, down from 72.4 percent in the first quarter, IDC said. AMD's share of the desktop market improved to 28.9 percent in the second quarter from 27.4 percent in the first quarter, according to IDC. In PC servers and workstations, Intel claimed 94.5 percent processor market share in the second quarter, up from 93.9 percent in the first quarter, IDC. AMD had just 5.5 percent of the workstation and server market in the second quarter, down from 6.1 percent in the first quarter, IDC said.
