主要目的是以現有R7模擬4核組態
並在相同時脈下比較兩種架構IPC

測試組態:
1. AMD Ryzen 7 1800X
關核心至 2+2 Core / 16MB L3
超頻至 4.0GHz
DRAM Command Rate = 1T
2. Intel Core i7 7700K
降頻至 4.0GHz
DRAM Command Rate = 2T
3. 其他細節 i.e. 板子、顯卡及其他配備、
還有原PO文者為何設定這樣的組態，
請參考 zolkorn 原文，在此不贅述。

測試結果:
(個人電腦排版 手機請見諒)
(較優者註記百分比，四捨五入至小數點以下第一位)
(LIB = Lower is better)

※ zolkorn 總結:
1. Zen IPC 落後 KBL 約10% 極端情況約落後~15%
整體而言約跟Haswell差不多。
2. Zen SMT 對多執行序加乘比 intel HT 高。
3. Zen 4C8T 遊戲性能可以說跟 7700K 幾乎在同一水平。
4. 測試組態細節可能多少影響參考價值，僅供參考。
5. Blog 底下 FB 留言: WinRAR 偏袒 intel;
(但這個來源 https://goo.gl/UDA1IX
顯示 7-zip intel架構還是贏滿多的)

※ Wccftech 總結:
1. Ryzen 在少數項目贏過 KBL，
如 Cinebench R15 Multithread, 3DMark Physics.
2. 7700K 在遊戲中最多贏~10%.
3. 以原廠未超頻/降頻時脈預估，
在遊戲中 Ryzen 4C8T 的表現約為 7700K 的85%，但價格只有60%.

※ 個人總結:
1. 常見的Synthetic benchmarks:
Cinebench R15 單執行序 KBL 贏7.4% 多執行序 Zen 贏0.7%;
Geekbench 4 KBL 皆贏~10%;
Super Pi KBL 皆贏~13%.
2. 3DMark Physics:
Zen 皆贏~6% (跟印象中其他評測趨勢相反，印象有誤請指點。)
3. WinRAR Zen 輸 KBL 很多。
4. AIDA Cache
讀/寫/移動 互有輸贏；
latency KBL大贏 (跨CCX不意外 https://goo.gl/1whILA)。
5. AIDA CPU
AES Zen 大贏一倍 (不意外，有專門的 AES coprocessor)；
浮點 KBL 大贏一倍 (不意外，架構硬體資源多一倍)。
6. IPC 跟 Haswell 差不多
但製程較先進 (GF14 vs intel22)，能源效率應該會比較優秀，
CP值也較高。
