GeForce RTX 2080、RTX 2070 同場較勁，7nm 製程 AMD Radeon VII 16GB HBM2 實測
AMD 選擇在農曆年期間將 Radeon VII 推出市場販售，讓我們有些壓力在。
相較於第一代 Vega 架構的 Radeon Vega 64 顯示卡，採用第二代 Vega 架構 GPU 的 AMD Radeon VII 除了 GPU 提升至 7nm 製程外，同時在記憶體部分也獲得非常顯著的提升；Radeon Vega 64 為 8GB HBM2，而 Radeon VII 是 16GB HBM2 記憶體配置。
託 TSMC 7nm 製程關係，AMD Radeon VII 不單單在效能方面獲得提升，同時也讓 GPU Die 面積從 495mm² 縮減至 331mm²。因為如此，AMD 才有機會在與 AMD Radeon RX Vega 64 相同大小的情況下，額外為 AMD Radeon VII 加入多 2 顆 HBM2 記憶體顆粒，讓記憶體頻寬提升至 1TB/s。
記憶體容量增加主要是因應遊戲對於顯示卡需求的提升，這也是因為使用者的螢幕解析度一直在進化。從過去的 720p、1080p、1440p 到頂級玩家追求的 3840 x 2160 解析度或是多螢幕同時輸出，這除了需要強而有力的顯示卡外，顯示卡本身所搭載的記憶體大小也有一定要求。
AMD 以 2010 年推出的 Battlefield Bad Company 2 512MB 顯示卡記憶體需求到 2018 年的 Battlefield V 需要 6GB / 8GB 顯示卡記憶體需求為實際例子說明顯示卡記憶體容量增加這件事；遊戲以外，Adobe Premiere 這型別的剪輯軟體對於顯示卡記憶體也有一定要求在。

作為 2 代 Vega 架構，與 Vega 10 架構的 Radeon RX Vega 64 與 Radeon RX56 相比，AMD Radeon VII 在頻率和延遲部分有所提升。
規格表中清楚看到，相較於 Vega 10 的 12.5 billion 電晶體數量，Die Size 較小的 Vega 20 電晶體數量來到了 13.2 billion，同時在 GPU 時脈都明顯變高；然而，Vega 20 的 Radeon VII 減少了 Compute Units 和 Stream Processors 的數量，但這樣的減少並未影響到 Radeon VII 的效能表現。
此外，Radeon VII 的溫度感測點也較 Radeon RX Vega 64 多了 2 倍。
這次對手我們找了 GeForce RTX 2080 作為比較對手，而我們選擇 EVGA GeForce RTX 2080 FTW3 ULTRA GAMING、EVGA GeForce RTX 2080 FTW3 ULTRA GAMING 與 AMD Radeon VII 公版卡進行測試。
採用 Turing 架構的 NVIDIA GeForce RTX 2080 與 NVIDIA GeForce 2070 都是 8GB GDDR6 記憶體，並且支援 Real Time Ray Tracing（即時光線追蹤）技術；目前支援 Ray Tracing 技術的遊戲多達 11 款，其中最有名氣的應該是 Battlefield V，但這款遊戲在 EA 稍早公佈的財報中，販售數量低於官方預期…
以下為支援 Ray Tracing 技術的遊戲：
。《Assetto Corsa Competizione》
。《Atomic Heart》
。《Battlefield V》
。《Control》
。《Enlisted》
。《Justice》
。《JX3》
。《MechWarrior 5: Mercenaries》
。《Metro Exodus》
。《ProjectDH》
。《Shadow of the Tomb Raider》
在這次測試中，我們選擇 Intel Core i9-9900KF 與 ASUS ROG Maximus XI Hero（WI-FI）作為測試平臺。

在這次測試中，我們選擇 Intel Core i9-9900KF 與 ASUS ROG Maximus XI Hero（WI-FI）作為測試平臺。
就目前 AMD 釋出的驅動，在我們測試條件（2560 x 1440）下，AMD Radeon VII 遊戲表現基本上是落後 EVGA GeForce RTX 2080 FTW3 ULTRA GAMING，但與 EVGA GeForce RTX 2070 FTW3 ULTRA GAMING 相比的話，在很多遊戲下是具有一定贏面。
3DMark 11 部分，EVGA GeForce RTX 2080 FTW3 ULTRA GAMING 最高可以領先 28%，但是在 Performance 模式下，GeForce RTX 2080 領先 AMD Radeon VII 僅僅只有 3%。
只是來到 3DMark，AMD Radeon VII 只有在 Time Spy 和 Time Spy Extreme 模式下大幅落後 EVGA GeForce RTX 2080 FTW3 ULTRA GAMING。
遊戲方面，AMD Radeon VII 除了在 DirectX 12 的 Sid Meier’s Civilization VI 落後 22.9% 外，其餘遊戲介於 7 ～ 14% 間。
對於 EVGA GeForce RTX 2070 FTW3 ULTRA GAMING 落後與 AMD Radeon VII 並沒有太大意外，因為當初 CES 的 AMD Keynote 上對手是建議售價為 799 美元的 NVIDIA GeForce RTX 2080 而非建議售價 599 美元的 NVIDIA GeForce RTX 2070 顯示卡。
從 4GB HBM 記憶體的 Fury X 到 8GB HBM2 記憶體的 Radeon RX Vega 64 我們存在著很多幻想，現在 7nm 製程與 16GB HBM2 記憶體的 AMD Radeon VII 登場，似乎讓我們見到紅軍準備迎戰綠軍的一些影子。
以 AMD Radeon VII 的 699 美元建議售價來說，它有著一定的吸引力在，畢竟它不單單是為了遊戲，更可以用在影片剪輯和 3D 渲染上。沒有 Real Time Ray Tracing 技術是否很重要，也許是，但不會在這個世代的產品中抱著遺憾。
未來 AMD 顯示卡驅動陸續釋出更新，也許 Vega 20 架構的 AMD Radeon VII 會有著更佳，或是超越 NVIDIA GeForce RTX 2080 的遊戲表現。
