First independent ARM A15 Benchmark - Exynos 5250
Some exciting news, the first real-world benchmark has appeared for an ARM A15 chip, in this case the Samsung Exynos 5250, which has been launched in the latest Chromebook.


Chip Info - dual-core A15 @ 1.7 GHz & Mali T604 GPU.

The benchmark is Sunspider, which is not multi-threaded, i.e. does utilise multiple cores, so you can evaluate the actual performance (javascript) of a single-core., now we can see the performance improvement ARM has baked into their latest hardware



Courtesy of Gigacom, Sunspider on the ARM version of Google Chrome that comes installed on the Chromebook = 660ms (Lower is better). Compared to the current King of the Hill ARM A9 device the Galaxy Note 2 (Exynos 4412), which is clocked at 1.6 GHz, it achieves 972 ms accorded to GSM Arena, other sites have similar figures.

LOWER IS BETTER
Exynos 5250 - A15 @ 1.7 Ghz = 660 ms
Exynos 4412 - A9 @ 1.6 Ghz =972 ms

The 5250 is clocked 6% higher than the 4412, so if we adjust the results for CPU frequency parity
Exynos 5250 = 660 ms
Exynos 4412 @ 1.7 Ghz = 914 ms

This is not an exhaustive performance test!, but we can see that in this one popular benchmark that ARM A15 is ~30% faster than the A9 architecture when adjusted for clock speed.

To sweeten the deal further A15 SoC will run at a higher clock than A9s, Tegra 4 (T40) is stated to run @ 1.8 GHz with a bump to 2 GHz after a couple of quarters, just like Tegra 3. Samsung has the even mightier 5450, a quad-core variant of the chip in this test, rumored to run @ 2 GHz, combined with much more powerful GPU, and Android's software optimisations 2013 is going to be one hell of year for tech fans

1.7G A15单线程性能大约比1.6G A9高30%，看起来还不错。但是功耗暴增，30瓦时电池只能跑6.5小时续航，相比目前主流的四核A9功耗双核A15保守估计要高70%以上。

苹果确实是很明智，A15以目前工艺根本不可能做到手机上。

高70%哪不是作死。不过可能是这款棒子货不行。

三个月前就跟你们说，a9是在手机上应用的极限。a15巨大的面积不合适，功耗在28节点上也根本压不住。直到现在还有人在意淫德仪的15

“A15的整数性能不比A9高，追加的东西都是服务器用的玩意儿，比如硬件虚拟化、大内存地址扩展，这些东西手机用不到，平板也用不到。不论是对于手机还是平板，整数性能永远是最重要的，这点上，你上双核A15，还真未必能比得过四核A9。”
不过新Chromebook还是有点意思的，才Nexus 7 16G的售价，反正我觉的会比N7好玩有用

高通那个4核算是融合了部分a15的a9？

A15到底行不行就看德州仪器现在的囧境就知道有多挫了

所以水果A6才自己实现arm核，就目前A6的性能表现而言同频性能和A15也差不多一个档次了。当然A15的长流水可以彪高频

好奇明年三棒银河4和note3的CPU卖点会是什么。。。

谷歌的上网本是用三星的A15双核，不知道评测如何

看来intel统一手机市场指日可待

性能和功耗本来就是需要妥协的。
我继续看好intel

手头的伪A15双核，LGLTE2挺好用的，发热比小米1小，当然性能，拍照，内存，国际知名度被小米秒杀

intel肯定能打赢战争

另外就是，无论是高通和苹果都没有什么融合a15特性的说法，a15从来不是为了手机和平板设计，长一倍的流水线可以轻松突破2g，为的是争夺低端服务器市场

蓝星最强制程的intel当然会赢
