後記﹕
根據測試所得，雖然 Intel Core 2 Duo E7200 核心時脈相比 Core 2 Duo E4700 為低，但大部份測試均是由 E7200 所勝出，主要是 L2 Cache 容量及 FSB 速度較高的關係，但兩者實際差距並不遠。
Intel 將會於第三季推出 Core 2 Duo E7300 型號，核心時脈則會提升至 2.66GHz ，與 E4700 之間的效能差異將會比較明顯。但整體而言， Intel Core 2 Duo E7200 、 E7300 在性價比上沒有比上代有大幅提升，驚喜欠奉。
如果要說其最大賣點，將會是其超頻能力，今代 45 奈米相比舊有 65 奈米產品，平均而言有較出色的表現，原裝風冷下輕鬆達成 4GHz ，表現令人滿意 ( 按︰ Core Voltage 偵測錯誤，實為 1.35v) 。
稍後， HKEPC 編輯部將上演 AMD Phenom X3 8050 vs. Intel Core 2 Duo E7000/8000 對決，以彌補此篇的不足，敬請留意。
