Intel 22nm Atom BayTrail代號 Silvermont 四核心SOC
Ref:
http://techreport.com/review/24767/the-next-atom-intel-silvermont-architecture-revealed/3
最高效能下:
2X 單核心效能於z2760 Atom(1.8GHz,約相當於Snapdragon600 1.7GHz)
2.8X 多執行緒效能 (四核四執行緒 vs z2760雙核四執行緒)
相同功耗下(1W SDP, 1.7W TDP max):
2X 單執行緒效能
2.5X 多核心效能
搭配Gen7 GPU,是目前SGX545@533MHz的四倍效能
22nm 3D IC TriGate High-K製程帶來的功耗助益相當明顯
實測效能:
Sunspider 0.9.1:499ms (MSIE10)
Octane benchmark:~4000 points (Chrome26)
Mozilla Kraken v1.1:~6000ms (Chrome26)
-----------------------------------------------------------
AMD Temash next generation 28nm Quad-core x86 SOC
A6-1450 1GHz四核(Turbo 1.4GHz)
Ref:

http://www.overclock.net/t/1364086/sweclockers-amd-temash-apu-a6-1450-in-cinebench-r11-5
Platform: Acer Aspire V5-122P Windows NT6.2 x64
Radeon HD 8280 iGP @500MHz -> 2X Graphics效能於E450 IGP
整體SOC TDP約4~6W 以AMD來說算是了不起的里程碑
雖然和Atom SOC的總平台功耗1.7W TDP還有滿大的差距就是了@@
Cinebench R11.5 rendering高度平行化CPU測試:
Temash A6-1450 單核心效能約略高於Atom z2760單核心
四核心加起來差不多和第二代core i3-2367雙核心效能差不多
per-core還是不太理想,和BayTrail也還有些差距
功耗效率比就輸intel BayTrail Atom更多了,Temash花了更多電 效能還比較差
實測效能
Sunspider 0.9.1:605ms (MSIE10)
Google Octane:~3000 points (Chrome26)
Mozilla Kraken v1.1:~8000ms (Chrome26)
GPU效能則小勝BayTrail,3DMark06比BayTrail ES好一些
但不確定是否為Driver問題,intel一向需要update驅動後效能才會好看些
整體而言,intel 22奈米製程加上全新亂序執行架構的Atom明顯占有優勢
完全足以和ARM匹敵的功耗,和超越ARM非常多的效率比
AMD則是在效率上足以和ARM匹敵,在GPU上狂勝ARM
Tegra4或是Exynos5的高耗電、高發熱都在在點出ARM面臨的瓶頸
Intel在效率上、製程上大幅超越ARM後的競爭籌碼似乎較符合其半導體龍頭的地位
2013~2014的行動市場果然是精彩可期呀
