Question on processor based on factsheet

---

Motorola url: http://mediacenter.motorola.com/Fact...heet-353b.aspx(Screenshot attached for those who are on device.)

Line of interest:
Processor: 2 processor cores running at 1GHz each

Nvidia url: http://www.nvidia.com/object/tegra-2.html
Lines of interest:
CPU: Dual-Core ARM Cortex A9
Frequency: 1 GHz, per core

Does this mean we have an effective 2GHz processing power in this device.

On a side note, my laptop is a quad core 2GHz, with each core at ~500MHz adding up to 2GHz in all. So that line got be confused thinking.

I've never heard of a 500Mhz quad core processor, but I have heard of a 2Ghz quad core processor, effectively providing 8GHz of processing power.

Nah, it really doesn't work like that. Each core will only run at 1ghz MAX, the benefit to having a second (or more) cores is that while you are doing something the second core is doing background stuff and you aren't getting bogged down. Or if the app supports it it can use both. Here's where things get fun....if your app uses both cores running at 1 ghz each it can TECHNICALLY process as fast as a 2ghz SINGLE CORE but its more like you get 50%-75% more performance from the second core. So I guess TECHNICALLY it would be the same as a single core 2ghz CPU...but at the same time not really? A 2ghz single would do things faster on single tasks, but multitasking the dual core is way better IMO. Hope that helps some.

Check in any CPU analyzer. Mine is a quad core, and each processor gets noted as ~500 MHz. I think u can find it even in 'device manager'.

Initially I too thought that I was getting 8GHz of power in my CPU, only to find later that it was infact 500x4.

Strange, my office system (desktop) is a dual core, and shows it at each core at 3GHz. Will check once more on my laptop when I get home. This is crazy!

But good to know. Even the graphics part of it has 8 cores. Was going through the specs. It rocks!

Are you sure your processor hasn't been underclocked as part of some sort of battery saving feature? I don't think most applications can even utilize all 4 cores, which would mean individual applications would perform...pretty slowly. Right?

This has always been baffling me. I'll check today evening n update here. But now I am super happy abt the processor in atrix.

if you are in windows run cpu-z and post a screen shot.

Here u go.

its this processor. each core runs at a clock of 2ghz

http://ark.intel.com/Product.aspx?id=40480

according that screen shot, you have

2GHZ * 4CORES = 8GHZ

so... you had 8ghz all along!
