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 (java屏蔽script) 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

这个新Chromebook才卖249美元有点意思

我怎么看不懂，
求翻译。

30wh用6.5h，换成牛排的42wh的电池有9个多小时还好吧

问题是chrome OS有啥用啊=,= 实际用起来还是比传统系统差不少的
而且这货ARM的只能装WIN RT啊

黄老板怎么办，NV只能上A15了

啥？NV自己研制的ARMv8指令集的芯片，这货2015年能上市黄老板就阿弥陀佛了

28NM的tegra3+欢迎你默频1.7GHZ哦

现在移动设备功耗大头是屏幕不是处理器啊,低功耗处理器用半天省的那点电估计还不够你屏幕量一小时...

个人觉得还是atom好，目前razr i的评测是续航非常好，性能搞定双核a9没问题

nv 德仪 三星都把宝压在A15上了吧

三星押双路，Nv至少没放弃搞4核A9。
德仪同时当28nm和A15的小白鼠，被雷得天昏地暗。
