We only received a bare card from AMD. Retail cards will come with the usual accessories, like documentation, driver CD and power cables.

GOODS:       
Extremely compact
Power efficient
Dual BIOS
Support for AMD FreeSync
Supports AMD Virtual Super Resolution and Framerate Target Control

BADS:
Very expensive
No HDMI 2.0 support
Coil noise
Average clock speed well below advertised 1000 MHz
Fan doesn't turn off in idle
Complicated overclocking
No backplate

CONCLUSION:
I see the R9 Nano as the optimum choice for 2560x1440p gaming, with most titles being well playable at 4K if you turn off AA and are willing to reduce settings a little bit.

For 1080p, the card seems to be overkill, especially due to its high price. Averaged over our test suite, we see the R9 Nano 10% faster than the R9 390X, just 3% slower than the R9 Fury, and 13% slower than the R9 Fury X at 4K. This means the card is 10% faster than the GTX 980 and 14% slower than the GTX 980 Ti. But all this doesn't matter if you need a compact card as the R9 Nano is the fastest choice with such a form factor.

In addition to the AMD review sample, we purchased a retail Sapphire R9 Nano, which is the exact same card in terms of components, PCB design, and specifications. Due to AMD's approach to frequency selection, each card will perform slightly differently because each board's heat output is slightly different, which will change the selection of clocks to stay within the power limit. Between both our samples, we see the AMD reference board in the lead consistently with roughly a 1% performance advantage. While this is new for AMD, NVIDIA cards have behaved like this for years.

Once you cram the card into a small case with limited airflow, the cooler will ramp up to keep temperatures in check, resulting in a somewhat noisy 41 dBA, which is definitely not something you'd want in your living room. What really turns me off is the massive coil whine on the AMD sample; we recorded it for you in our video on page 35. No matter the FPS, you will always hear an electrical chirping that will change in volume and frequency depending on the game's scene, which makes it even more pronounced. I wonder how their engineers missed this again (remember the HD 7990?).

結果AMD最後都係死死氣氣咁俾卡佢地測
不過TPU似乎已經入左張Sapphire

其實其他比較有良心既REVIEWS都指出1080P下NANO超到盡都唔及980超到盡
HBM玩2K/4K真係好有幫助, 可惜GPU跟本追唔上
AMD次次都玩領先但係TIMING錯鬼哂, 分分左蝕埋間廠, 哈
有良心既REVIEW主要既批評都係NANO冇HDMI2.0, 溫度嘈音連COIL WHINE問題一放入箱入面就食哂屎

岩岩出左CF REVIEW
