Everyone loves a good benchmark, right? Benchmarks are great, but they tell you anything about real world usage. For example, the Nexus One running 2.2 blows everything else away in benchmark tests because of Froyo's great JIT compiler.
We have heard that the 1 GHz Hummingbird in the Samsung Galaxy S phones is the best system-on-a-chip with Android yet. More powerful than Snapdragon, more powerful than the TI OMAP 3630-1000 (the Droid X's processor), perhaps even more powerful than the A4 powering the new iPhone and iPad (although to be fair, that is a Samsung designed processor... and the same one in the Hummingbird, so the only difference is the graphics processing).
You might wonder what a system-on-a-chip, or SoC, is. If you already know, just skip this paragraph. An SoC is simply a single chip that contains both the processor and GPU, graphics processing unit. You can't simply stick the best of each together and hope for the best, they need to work harmoniously and hopefully synergistically. An SoC is the powerhouse behind all the great, powerful mobile devices. Most of them use a variation of an ARM processor (ARM 11, ARM Cortex- A8 etc.). These are licensed out to manufacturers and designers. The processor in the Moto Droid and Droid X are designed by Texas Instruments. The processor in the iPhone 4, iPad, and Galaxy S phones are designed by Samsung. The SoC in those Apple products uses a processor for Samsung, but the SoC is designed by Apple. The entire SoC for the Galaxy S phones is made by Samsung.
