如果FURY X買得到，那當然以FURY優先，那是不用懷疑的~~

物以稀為貴，之前小弟也講過FURY X不是賣到沒貨，而是沒貨可賣，很多合作
廠商根本拿不到貨源或數量相當有限，這情形恐怕要到年底才能逐漸緩解，並影
響次級FURY與NANO出貨，目前情況下，FURY X價錢遠高於官方定價，也
是沒辦法的事...


遊戲性能上可參考TPU，4K下FURY X約295X2八成左右，每瓦效能遠優於
295X2，但如樓上luke兄所講，CF會因遊戲支援度產生”效能振盪’的情形，其
振幅必高於單卡，這是一定要注意之處

另295X2為GCN 1.1，FURY則至少為GCN 1.2以上，其差異可參考以下

• One of the key features of the third-generation GCN is updated instruction set architecture (ISA). While there are not a lot of details available at the moment, expect the “Tonga” and other GPUs based on the GCN 1.2 to support certain new capabilities that improve its overall efficiency when it comes to computing.

• Another thing featured by the new GCN is yet again improved tessellation/geometry processing performance. It is unclear whether AMD redesigned its geometry processors in general, or just increased their amount, but tessellation should work better on the GCN 1.2 compared to previous-gen GPUs.

• To reduce requirements for memory bandwidth and improve performance in high resolutions, the GCN 1.2 supports delta colour compression. The latter is an image compression technique that encodes a row of pixels by replacing their colour information with values that represent difference between subsequent pixels (e.g. if one pixel in RGB format is 255:0:0, the other one is 255:1:1, the third one is 255:2:0, then with delta compression the sequence can be represented as 255:0:0, 0:1:1, 0:1:-1).

• The GCN 1.2-based GPUs will also feature a new multimedia engine – which comprises of universal video decoder 6.0 (UVD 6) and video encoder engine 3.1 (VCE 3.1) technologies – as well as a new high-quality scaler for video. There is no word about support for ultra-high-definition (UVD) video codecs, such as H.265/HEVC or VP9, so it looks like the new GPUs will not support them.



DX12 VRAM STACK的問題，如果API直接支援當然很好，但恐怕沒有那麼樂
觀，其硬體層級可能需要遊戲商去介入才有辦法，目前尚不明朗
