Why do Android phones have more cores than computers?

As you've already noted, the big.LITTLE combination strategy (technically, HMP, Heterogeneous Multi-Processing clusters) is the primary reason for so many (and sometimes overwhelmingly many) cores. A ...

How to tell what architecture an APK is intended for?

One (rather crude) way to see what architecture an APK's native libraries are built for is to unzip it (it's only a zip file) and take a look at the libs folder - if the application contains any ...

Why do Android phones have more cores than computers?

The reason is as simple as much as complicate. The short answer is "because the mobile phone market has never been and is not driven by Intel". The long answer is way too long to resume here, but ...

Why do Android phones have more cores than computers?

There are two factors going on, one very practical and the other historical. The practical reason is the use of mixed architectures in phones. Power consumption is critical for phones and phones ...

Where is the baseband firmware stored and how does Android interact with it?

Is the firmware really stored in another eMMC than the Android firmware? No. Baseband firmware, kernel and userspace Android are all stored on the same eMMC (there might be some exception but I don't ...

Why do Android phones have more cores than computers?

It's crucial for a phone to be able to provide computational power in short bursts (we need certain apps to be fast) but to also avoid overheating (heat dissipation is much more difficult for phones ...

CPU-Z shows 8 cores, but 4 of them are stopped

Is there any way of activating all cores? You can't. The hardware is not designed to have all 8 cores active. The reason for this is that this Octacore CPU is actually based on big.LITTLE technology,...

Android apps for "armeabi-v7a" and "x86" architecture: SoC vs. Processor vs. ABI

The number of hardware devices that use x86 was never very high. Some years ago Intel had some x86 processors (Intel Atom) that were used in some Android tablets (e.g. Samsung Galaxy Tab 10.3). ...

When a processor speed is given for a multi-core processor, is that the cumulative speed or the speed of the individual cores?

Frequency is not cumulative. The chip runs at 1.8 GHz, each of the cores runs at 1.8 GHz, all four cores run at 1.8 GHz. If one car travels at 100 km/h and another car runs beside it at 100 km/h, you ...

CPU-Z shows 8 cores, but 4 of them are stopped

It all depends on how the apps that are running are written and if they can actually make use of multiple cores. Even if you are running a heavy application, if it cant make use of all the cores, the ...

CPU-Z shows 8 cores, but 4 of them are stopped

That is perfectly fine. Why would 8 cores be active if you are in cpu-z app. Four cores are let's say active all time, and other four are jumping in if needed, cpu-z don't need 8 cores trust me. Try ...

Can I run an Android emulator on a computer with an AMD processor?

VT-x is the Intel virtualization technology while SVM is its equivalent for AMD. I think either your computer doesn't have such feature or it is not enabled. Go to the BIOS and see if it is ...

Is there any relation between processor clock speed and heating effects?

tl;dr There is a direct relationship between the amount of power used by a processor and its clock frequency. The higher the performance , the higher the power consumption and heat generated (meaning ...

Why do Android phones have more cores than computers?

First, Java virtual machine can historically benefit from multi-core more than typical desktop software. Even if you write a single-threaded app in Java, it will run faster on a multicore because most ...

Reviving my phone after a small part of it (eg the processor) overheated

I managed to turn my phone on by myself. Hopefully it will continue working. I warmed up 2 plates in the oven to 80 Degrees C, took them out, and put a third (cool) plate with the phone on top of them....

Do I need a smartphone with more RAM or one with a higher processor in order to load a big excel file faster?

RAM should not be an issue with smartphones that have 6GB or 8GB of it (I have 1GB and Excel workbooks load fine - not really large ones) . So, in that case, it would be the processor. Also, a ...

CPU-Z shows 8 cores, but 4 of them are stopped

Yep, same here thought which brought me here but then noticed also if you fire few apps and then switch between these and back to CPU-z it will shortly show activity on all cores.
