没看懂,第一个测试是得分越多越好,第二个是得分越少越好?作者: foxroz2003 时间: 2011-6-4 20:38
Caffeinemark3 测试的是Java硬件加速的。(原文:CaffeineMark scores roughly correlate with the number of Java instructions executed per second, and do not depend significantly on the the amount of memory in the system or on the speed of a computers disk drives or internet connection.)所以tegra2比atom快应该是因为有java硬件加速。作者: Edison 时间: 2011-6-4 20:46

Oak Trail是款双核处理器,集成单核535?
Under the unit 9.4 MFLOPS Linpack managed to score. This maintains the cpu miles behind the Tegra 2, for example, in many modern tablets is. That chip in the same test scores about 36 MFLOPS.
The benchmark Quadrant is a sum of different sub-benchmarks that both the CPU and the GPU of the tablet test. The total score stood at 1978. This tablet is faster than many smartphones, but modern Android tablets score on this test between 2000 and 2500 points.
linpack 成绩不错,9.4MFLOPS。作者: 6神-kepler 时间: 2011-6-4 23:47
ATOM LINPACK 9.4MFOLPS?
真的让tegra 2 的linpack 36 MFOLPS 情以何堪啊!
话说那个楼上的某位是不是被intel 打了鸡血啊!~~~累不累啊作者: PRAM 时间: 2011-6-4 23:51
实测浮点峰值是指Linpack测试值,也就是说在这台机器上运行Linpack测试程序,通过各种调优方法得到的最优的测试结果。实际上在实际程序运行过程中,几乎不可能达到实测浮点峰值,更不用说达到理论浮点峰值了。这两个值只是作为衡量机器性能的一个指标,用来表明机器处理能力的一个标尺和潜能的度量。作者: PRAM 时间: 2011-6-4 23:53

Java性能不太适合拿来评价一个系统的性能,因为不同的JVM实现本身就可能差距几十倍的性能。CaffeineMark是个Java程序,不过这个是标准的Java,而不是Android中的变种Java,所以,需要一个Java VM for Andorid/X86才行。。。。这个,实在比较诡异了。
Java的linpack就更没有意义了。Atom的SSE指令集轻松到达GFLOPS的级别,但是这个linpack的测试程序是JAVA写的,如果JVM又不包含JIT,或者JIT出来的机器码是用整型模拟的浮点,那就完全没有利用到Atom的浮点能力。Tegra2不带NEON指令,倒也不吃亏。另外:This test is more a reflection of the state of the Android Dalvik Virtual Machine than of the floating point performance of the underlying processor. Software written for an Android device is written using Java code that the Dalvik VM interprets at run time.
