本站的伺服器自 2006 年採用 Intel Q6600 至今已屆五年，
雖然近來無恙但考慮到器材老舊與廢熱排放，
索性趁著記憶體價格崩盤及溽暑來臨之前物色新的硬體平台，
並試圖打造峰值耗電小於 150w 的節能伺服器。
以下為 Intel Pentium G620 的 ubench 設定參數與測試結果，
與去年的結果有過之而無不及，
新一代低階雙核效能居然能與舊款中高階四核比肩，不禁讓人讚嘆時代的進步。 😀
| Processor | Original V. | Original F. | Reduced V. | Reduced F. | |
|---|---|---|---|---|---|
| Server | Pentium G620 | auto | 2.6 GHz | auto | 1.6 GHz |
1.6 GHz (downclocked)
