It’s a typo.. the OmniaHD ships with a 600 Mhz CPU

Having read a lot of mobile phone PR’s and reviews, and being interested and a wee bit knowledgable in the area of Computer Architecture, it is impossible that 1 Ghz = 600+430 Mhz.

a) The 1 Ghz is a typographic error that has inadvertently crept in.

b) Samsung has silently upgraded the Omnia i8910HD SoC to it’s 1 Ghz Hummingbird processor announced recently. The thermal and power envelope of this new low leakage 45 nm process processor are in the same region, so integrating it with the existing SoC in place of the old 600 Mhz 65nm ARM Cortex A8 is not such a big deal

Let me make it clear. CPU speeds of varying architectures cannot just be added to get the total speed. The CPI, issue count etc. of each ISA differs, and adding in sequence just doesn’t give the total clock speed.

That is why 2 Ghz Pentium 4 + 625 Mhz (ATI Radeon R520) != 2.625 Ghz processor.

Even in the same ISA with multi-core solutions it is not possible. That is why 2 Ghz Core 2 Duo!= 4 Ghz Core 2 Solo

@SammyWiki: Rightly said but a gigahertz of speed is tempting then by saying it has so and so megahertz of speed.

I would think that the average consumer would be more interested in capabilities and what the phone can or can’t do for them, clock speed is not the be all and end all of performance.

That said, of course some of us are geeky enough to look closer at the details!
