III. Palm Pre CPU/BUS Performance Tests-500/600/720/800 MHz (new section): Two different kinds of benchmarks; Javascript performance and raw CPU bus throughput. Both measure and scale to the CPU clock speed. The Javascript test is the same tests used in iPhone, Android, and Pre comparisons on the Internet. The SunSpider test is a JavaScript benchmark. This benchmark tests the core JavaScript language only, not the DOM or other browser APIs. It is designed to compare different versions of the same browser, and different browsers to each other.
These results (not all shown) show that the Phone is indeed running fasterand past 800 Mhz the phone cant feed IO any faster to the CPU.
SunSpider test (
http://www2.webkit.org/perf/sunspide...nspider.html):
(3 tests each and took median result. lower is better)
500 static (OS1.3.5.1 w/ optimized kernel): 23695.6ms
600 scalable OS1.3.5.1 (w/ optimized kernel): 20139.4ms
600 static (OS1.3.5.1 w/ optimized kernel): 20062.6ms
600 static (OS1.3.5.1non-optimized kernel): 20228.4ms
*720 static (OS1.3.5.1 non-optimized kernel): 16680.2ms*
*720 static (OS1.4.0 non-optimized kernel): 15050.4ms*
**800 static (OS1.3.5.1 w/ optimized kernel): 14936.6ms**
**800 static (OS1.4.0 w/ optimized kernel): 13607.2ms**
Note: Bus (I/O) speeds were the same (as expected). The SunSpider tests are faster due to the greatly enhanced javascript engine of OS1.4 vs. 1.3.5.1.
Conclusion: kernel in OS1.4 (better javascript engine) is more effective than OS1.3.5.1
