UPDATE: Samsung India website has demystified the 1GHz equation.
As the world was bemoaning about the fact that India will be getting a 1GHz Omnia HD, one of our commenters left a very plausible comment.
Samsung India might be adding up the clock speeds of the CPU as well as of the DSP which, if we count, goes in excess of 1GHz. Omnia HD houses an OMAP3430 application processor along with TMS320C64x DSP. This is the breakup sourced from Wikipedia.
OMAP3430 – 600 MHz ARM Cortex A8 + PowerVR SGX 530 GPU + 430MHz C64x+ DSP + ISP (Image Signal Processor)
Ok, technically speaking Samsung could be right in claiming this but if we see from a consumer’s perspective, it looks to be a shoddy marketing attempt to lure innocent buyers.
[Thanks Ardalan!]
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! 🙂
@SammyWiki: Rightly said but a gigahertz of speed is tempting then by saying it has so and so megahertz of speed.
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 😛
@Karthik Ramgopal-wow!man u knw abt this stuff n thats why i want to know if it’s a typo or da hummingbird processor,man i wud really like to get my hands on a 1ghz phone!!
It’s a typo.. the OmniaHD ships with a 600 Mhz CPU
