The Samsung slate was 5.11 times as fast. Question: how much of that is down to the Core i5 being a faster CPU, and how much is down to a less well optimized Chakra engine?
Incidentally, the Apple iPad 2 which has an Apple A5 processors running at around 890 Mhz is approximately 33% slower on the SunSpider test. Since the CPU is clocked 45% slower that is a good result for the iPad 2 and Safari.
A Google Nexus 7 on the other hand which has the same Tegra 3 chipset as the Surface is about 55% slower than the Surface, which is poor.
Can you include the actual comparison URL so we can compare to other devices?
@Alex: I think that’s the one –> sunspider
It’s likely that JIT (Just-in-Time) compilation of js is disabled, maybe they haven’t done the ARM code for doing. Another less likely possibility is MS actually enforcing the same restrictions other programs have on the RT platform by not allowing executable memory. This is highly unlikely, so an update with probably have JIT for ARM and fix the performance.
