Hello, I have a laptop with core i3 quad. I read an article and wiki, it said that Core i3 only has 2 cores. I opened device manager and it said that it's 4 cores. Am I drunk? This is the picture http://www.mediafire.com/?a6gsuow5hud4hdg
You are seeing an extra 2 cores for i3 hyperthreading technology. It can more efficiently run multiple threads of programs. It is moderately faster by about 5-15% as a result but not as fast as an 2 cores could make it.
So no, you only have 2 cores and each have a bit of extra circuitry to improve multi threaded performance slightly, but windows cant really differentiate between them and real cores.
Either you or Windows is.
The Best specs an i3 can have is 2Cores/4Threads. Not 4 Cores. Its showing the Threads. Try check WEI ( Windows Experience Index ) and it will show you accurate results and an assessment of your PC along with specs including the model no and cores.
P.S - If the model is actually a M350 then still its not a Quad Core CPU.
If anyone's answer helps you , please select it as the solution for your thread.
The only Intel quad core CPUs for laptops are the Core i7 CPUs with the "MQ", "MX" and "HQ" designations, like the Haswell generation i7-4700MQ. There are i7 CPUs with simply the "M' designation like the i7-4600m, but those are simply dual core CPUs with hyperthreading.
In short... All mobile core i3/i5/i7 CPUs are dual core CPUs with hyper threading. The only exceptions are Core i7 CPU with the following designations; those CPUs are quad core CPUs with hyper threading:
