It would be easy to think PC sales dropped worldwide last year amid chip shortages, but that conventional thinking would be wrong. As it turns out, Canalys reports that PC shipments grew 15% year over year in 2021 and were up 27% over 2019, with a whopping 341 million units sold.

While the fourth-quarter numbers were up just 1% over the previous year, 2021 was still the best year since 2012, according to the firm.

As Canalys senior analyst Ishan Dutt pointed out, PCs had a great year in spite of chip supply issues, and he sees PCs as firmly entrenched as part of our work and leisure lives, with it becoming the norm to have multiple PCs in the same home in developed areas of the world.

“For the market to post double-digit growth over an impressive 2020, despite the constant cloud of supply constraints, speaks volumes about how strong PC demand has been over the last 12 months. Taking a long-term view, the most important developments in 2021 were the large increases in PC penetration and usage rates,” he said in a statement.

The big winners in 2021 were the Big 3 PC makers: Lenovo, HP and Dell, with Apple coming in fourth. It’s worth noting that while everyone had a good year, as the chart below shows, Apple had the largest growth number year-over-year at 28.3%, while 回收筆電acer was second with 21.8% growth in spite of being fifth overall in terms of shipment numbers.

In terms of market share, Lenovo and HP were the clear winners with 24.1% and 21.7%, respectively. Dell was third with 17.4% with Apple fourth with 8.5%

Although chip shortages are expected to persist into the new year, and there is speculation that the education market may be saturated, Canalys still believes that 2022 will be a strong year for PC sales. In fact, Canalys analyst Rushabh Doshi said the market would likely have been bigger in 2021 if not for the supply issues.

“The primary reason why we are in a shortage situation is that demand is outstripping supply. It is [definitely true] that had the supply situation been better, the PC industry would have grown faster, and be [even bigger],” Doshi told me.

He sees a market that will continue to expand into the future. “Looking at an unconstrained view, the demand for better and faster PCs is now more pronounced than ever, not just in work, but also at home. With the importance of PCs reinforced in the past two years, we believe that the growth is here to stay,” he said.

特約記者洪聖壹／綜合報導

受到疫情影響，今年intel難得在台灣舉辦桌上型處理器上市記者會，這也是全球少數舉辦實體上市活動的地區，活動現場有來自國內外共計 11 家廠商參與，並且展出採用第11代處理器的相關產品。

英特爾台灣分公司業務暨行銷總經理汪佳慧指出，採用14奈米製程的Rocket Lake，最高擁有8核心16執行緒，採用Cypress Cove微架構，不管是效能、圖形運算、AI 這三個區塊在第11代產品都有顯著成長，她也相當看好產品上市後在市場上的表現，同時也強調不管是半導體還是 intel 在台灣的 PC、資料中心、5G物聯網、AI 或雲端等，都會繼續投資台灣，並繼續與台灣第三方公司合作，一起服務全世界。

第11代 intel Core 桌上型處理器系列最高擁有 8 核心 16 執行緒，擁有三大特色，第一個是 IPC 的提升、第二是顯示效能的提升，再來就是超頻變得更穩定而且便利。

因應玩家需求，全新 Cypress Cove 微架構，讓整個 IPC 效能比上一代提升 19%，透過intel Adaptive Boost Technology(ABT)提升多核心、多執行緒表現。

第11代 intel Core i7、i5 桌上型處理器最大特色就是相容 DDR4-3200。i3 可以說是上一代的再提升，最多支援 DDR4-2666。在超頻方面，10代以前都記憶體控制上只能支援Gear 1，但是11代（部分i5與i7）可以支援到Gear 2，藉此讓 CPU 只要跑一半的頻率，就可以達到超頻需求，如此一來對於大部分的遊戲來說就具有更多的相容性，而且對於合作夥伴來說，操作性更簡單。

除了相容性，另一個亮點是針對機器學習方面，新增了intel Deep Learning Boost 功能（VNNI指令集），大幅度加速 AI 應用，另外 Gaussian & Neural Accelerator（GNA）使用超低功耗處理 AI 語音應用，而且 PCIe 也提升到Gen4 ，這代表將大幅提升 NVMeSSD 讀寫效。

在顯示核心方面，內建 UHD Graphics 採用最新 X 架構，提升能源效率，另外受惠於新的媒體區塊，新增了 AV1 硬體解碼，相同編碼效率相較 HEVC/H.256 提供更精緻的畫質。

在 500 系列晶片組，Z590、H570 用以銜接處理器的 DMI 3.0 升級到 8 通道，撐起 NVMe SSD 和 USB 3.2 Gen 2X2 所需頻寬，也能夠以獨立晶片或者無線網卡支援 Thunderbolt 4 或者 Wifi 6W。H570、B560 晶片組更首次支援記憶體超頻。新的處理器提供Gen 2 和更寬廣的時序調節，Windows 作業系統環境，能夠透過 intel Extreme Tuning Utility 及時調整運及時調整運作記憶體時脈。
