點解有d graphics分數
iPad Air 會低分過 iPad 4 嘅

因為粒u行64bit, 4th gen粒u行32bit
有啲指令用新u行會比原生32bit慢
所以講cpu快咗好多，係整體咁講，而細分未必會完全反映新u整體性能

Doubled the WiFi performance, nice.

Wifi performance 不錯, 不過有ac 就更好

薄重可以維持同樣使用時間，Good!

因為 iPad 4 GPU 同 iPad Air GPU 架構唔同
iPad 4 係完整雙核, iPad Air 只係渲染部份雙核
The regression in triangle rate performance compared to the iPad 4 is explained by differences in how Series 6 and Series 5XT GPUs scale in width. Whereas 5XT replicated nearly the entire GPU for "multi-core" versions, multi-cluster versions of Rogue only replicate at the shader array.

雖然我知道有改善係好過無改善,
不過就算佢行到 800MB/s 甚至 8GB/s 我都唔知會有咩分別...
wifi performance我想佢測試接收能力多過傳輸速度.

iPad Air Teardown

iPad Air 的A7 Processor型號為 APL5698, 而 iPhone 5s 的A7 Processor型號為 APL0698, 因此兩者可能存在某些差異.
這部被拆解的 iPad Air 的 IPS Display是由 LG 供應的.
1GB RAM (LPDDR3 SD RAM) 不是整合在 A7內.

SGX 5XT multi core in iPad4 is heavy on triangle performance and light on shader performance. The triangle performance is a result of 5XT being a multi core design, I.e. everything is duplicated, so a 4 core has x4 the triangle setup, 4 times the fill rate.
For modern applications, shader performance is much more important. Rogue implements a cluster configuration, each additional cluster adds another chunk of shader performance, however it does not necessarily add triangle performance. The amount of triangle performance will be determined on a core basis. This approach results in low level triangle figures appearing to disappoint, which has some impact on older tests, but results in modern applications, and those benchmarks that simulate them, getting a big performance boost compared to 5XT.

無ac個速度都上到勁過note 3嘅ac?
mimo真係咁勁?

另外舊電細左20%都仲可以keep住ipad3/4表現,今次真係好神

我估計主要係lcd mon用咗新設計的背光模組, 所以慳咗電.

Moto X 同Htc one 係咪食左過期春藥？
