更高時脈、8核心不鎖頻
全新AMD FX-8350 Piledriver處理器登場
雖然 Intel Ivy Bridge 處理器以出色的性能牢牢控制了中高價市場，而 AMD 則已把業務發展重點放在整合 GPU 的 APU 處理器上，不過為針對需要高效能的 AMD 用戶，在 Piledriver 架構的 Trinity APU 推出後， 隨即推出不含 GPU 的 Piledriver 架構 FX 處理器，以「 Higher Frequency, Unlocked, More Cores at every price points 」作為賣點，為 AMD 用家帶來升級機會。

後記﹕
就架構上來看， 雖然 Piledriver 仍及不上 Intel 高階的 Core i7 Extreme 及 Ivy Bridge Core i7 處理器，但不可否認 Piledriver 具有一定之進步，考慮到這個進步沒有通過轉用新的工藝而是出於 AMD 工程師的努力，值得向他們加以讚許。而 AMD 在經歷不功能的 Bulldozer 架構後， Piledriver 登場時採用較低的定價，降低玩家的期望，也有助新一代 FX 處理器的成功。
