Nano 除了體積對於小機殼是救贖之外, 其他人乾脆買Fury X 來降頻用就好  至少想拉高效能的時候還有空間可以比Nano拉高點

有人說Nano的ASIC QUALITY是挑過的, 體質比較好的晶片, 否則沒有辦法在不閹只稍微降
頻的情況下耗能從275降到175, 另種說法是175只是虛報, 比較正確的應該在190上下...

拿掉FP64 AMD的HSA和進攻HPC都不用玩了...

你不買我不買自然有人會買 反正目前有HBM的顯示卡慘量就那樣 AMD定它們自認為賣的光的價格,也不算做錯啥事

剛剛在PTT看到的....Nano其實是900MHz... https://www.ptt.cc/bbs/PC_Shopping/...1060.A.AC0.html ... 但TDP從之前的275W降低到了175W，少了100W，核心頻率最高1000MHz，看起來只比Fury X 少了50MHz 但實際上這個1000MHz是偶爾才能達到的，平時頻率只有900MHz左右，AMD表示最後的10% 頻率（900到1000這部分）要消耗50%的額外功耗，所以這也是R9 Nano更節能的原因之一。...

核心時脈只差150Mhz效能不知道會差多少?

依照下面這張PPT來看 http://www.coolaler.com.tw/image/ne..._nano_ppt_2.jpg nano用34fps Fury X用42fps來計算 42/34=1.235 1050/900=1.167 以此來看最後那150Mhz提升的效益蠻好的，不過也很吃電就是

賭看看過陣子華碩會不會拿兩顆nano來兜雙核卡

AMD還有張FURY VR沒出呢... 看AMD是拿XT還NANO拼就知道了...

Techpowerup對於Nano的牢騷
http://www.techpowerup.com/215776/a...by-tpu-not.html There won't be a Radeon R9 Nano review on TechPowerUp. AMD says that it has too few review samples for the press. When AMD first held up the Radeon R9 Nano at its "Fiji" GPU unveil, to us it came across as the most promising product based on the chip, even more than the R9 Fury series, its dual-GPU variant, and the food-processor-shaped SFF gaming desktop thing. The prospect of "faster than R9 290X at 175W" is what excited us the most, as that would disrupt NVIDIA's GM204 based products. Unfortunately, the most exciting product by AMD also has the least amount of excitement by AMD itself. 由於Nano數量太少，以Techpowerup那麼知名的網站，也無法拿到樣品測試， 因此TPU將沒有Nano的Review。文章也提到，一些友站也因為同樣原因，無 法進行Review，可見數量相當稀少，連TPU都拿不到，產能應該存在嚴重問題... (TPU算是公認比較中立的網站，AMD應該會優先給對自己比較友善的單位) The R9 Nano, on the other hand, has the potential for greatness. Never mind the compact board design and its SFF credentials. Pull out this ASIC, put it on a normal 20-25 cm PCB, price it around $350, and dual-slot cooling that can turn its fans off in idle, and AMD could have had a GM204-killing product. Sadly, there's no way for us to test that, either. We can't emulate an R9 Nano on an R9 Fury X. The Nano appears to have a unique power/temperature based throttling algorithm that we can't copy. 這段和小弟的想法一致，不要去管什麼ASIC，不要去管什麼卡長，找一個效能 與耗能的甜點就好，Fiji就會相當有競爭力。不過現在產能還是拉不上來，縱使 DX12塑造了一個美好的憧憬，但沒有產能就無法提高競爭力。個人預估年底或 明年初產能問題應該可以逐漸紓解，AMD的市佔有望再拉高一些...
