"@BlackberryScoop: The hardware specifications for #BB10 are going to be finalized by the end of the month and sent of to #BB10 manufacturers."
Seems like it's not finalized yet, so everything is still speculation.

they were suppose to be making the phones this month, so if the hardware hasnt been finalized then they are running behind which is not a good thing to think about. I am going to say that BScoop has got this one wrong and hope they are making the devices already.

Let's say you have an app, and it can complete a task in 5 seconds on a 2Ghz CPU. The same app, if designed to take advantage of multi-CPU processing, can theoretically complete the same task on two 1Ghz CPUs in the same 5 seconds. The advantage being, it would use less power because power use isn't linear.
Now, in the real world, there are a bunch of other factors that will make it impossible for the same task to be completed in the same amount of time. Things like badly written app, missed cache hits, memory bandwidth, out-of-order execution misses, and a bunch of others. Even with all that, the power savings is enough to make laptop makers use a dual-core 1,3Ghz CPU over a single core 2.4Ghz one.
Now, that's when the CPU is in use. The issue lies in when the CPU package is idle. Obviously a dual core CPU at idle consumes a lot more power than a single core one. Not exactly twice as much, since there are other things in a CPU package such as cache memory, and for mobile phone SoCs, GPUs.
That's not the end of story though. The more cores you have, the smoother your device will run. The is because if a core is busy with a task, and there isn't another one available, it has to wait until that task is completed. Multi-core computers tend to have less hiccups and the experience tends to be smoother overall.
Basically, the more you use a multi-core CPU package, the more advantageous it is from a power stand point to have it be used, over a CPU package with few cores.. Although double the cores can theoretically double performance, it usually doesn't happen. It's closer to 50-70% increase rather than 100%, although some tasks do show 100% increases.. Power usage can potentially be less on 4 cores than on 2, but it depends on usage patterns. If your usage pattern has it so that 2 cores are constantly running at close to top speeds, it's probably better from a power stand point to run 4 to keep the speed ramp up contained because CPU power consumption is not linear with speed.
That's the basics on effect on performance and power usage for multi-core computers. There's a lot I didn't get into, including the reasons why power consumption isn't linear, but that would turn this into a 10 page post.
Addendum: It is very easy to write code to shut down any number of cores. The LG Optimus G has the option to shut down 2 of it's 4. So basically, there's really no downside to using 4 cores over 2 if you use this option, with the obvious exceptions being additional cost, and additional space requirement in the device. Of course if you're Apple, you won't do it yet, because you figure that option is too complicated for normal people to understand.

also you can factor in that sometimes, like in modern cars, you can shut down cores when not needed the same way a V8 engine can shut down and run on 4 cylinders to save fuel.

Why complain about the price and specs your gonna buy it also its a good blackberry now to buy why complain. If it was an iphone you would buy that asap even if I had **** specs so why complain cos its a blackberyy, I'm not a BB fan boy but from what I see the OS is so good IDK about specs.

Z10 specs, price point - Not so impressed....
Very well put CrackedCookie...and with that I'm gonna go check the specs on my wife's hair dryer to make sure Remington isn't getting over on her! Later!

I just want to throw this out there as someone on the android side of the fence. It's about the user experience.
I currently own a Galaxy s3, so do millions of other people and is the only phone in the USA to out sell the iphone on every carrier it's offered on. Why is that? it's not the specs. The HTC One x has the exact same CPU and Storage options (minus the micro sd slot) the One X has a better screen, better camera and is built out of better materials and has sold so few that HTC is floundering. The user experience is much better on the s3 with gestures that it elevates it above another android device.
Now before you rush and say look at the Nexus 4, it's the price. The LG optimus G is the exact same phone as the nexus 4, plus LTE, that you can get cheaper (with a contract) on the carriers that offer the S3, but people are STILL buying the S3, so clearly specs don't matter to lay people.
the only people that really give a hoot about specs are people on forums. Go to a best buy or a carrier's store and ask someone who just bought a smartphone, how many cores it has, heck even who made the cpu... please reply with the answer...
I am not impressed with the z10 specs per se, but I am impressed with the gestures, ui and usability of BB10 and if the z10 isn't straining under bb10 or apps then why should I care?
