Resolved Are all present-day CPUs 64-bit?

Is it true that the present-day CPUs are all 64-bit and thus there is no need to check it before purchase?

 

Sorry for my confusing question.
Assuming that I will buy a new MATX motherboard when my present one dies and will use a 64-bit Windows, how can I check that the CPU is 64-bit before purchase? Will it be specified on the package box?

 

Pentium, Core and Celeron are all mainstream CPUs, so those released after 2005 must be 64-bit.
Am I right?

 

Understand just because a CPU is 64-bit capable, that does NOT mean you must use 64-bit Windows. That said, to take advantage of today's hardware performance capabilities, you typically want lots of RAM and to take full advantage of 4Gb or more of RAM, you need a 64-bit operating system.

Note too that hardware has been 64-bit ready LONG before 64-bit operating systems were commonplace.

Note if your motherboard supports more than 4Gb of RAM, it MUST support a 64-bit operating system and any CPU supported by the motherboard will too. In other words, don't worry about it.

 

Just out of interest, is what I wrote in my post#5 above correct?

 

But it seems otherwise according to the pictures on http://en.gecid.com/cpu/intel_core_i3-4130/

 

Did you look at your own pictures? Your picture CLEARLY says, Intel 64 architecture and it says it supports EM64T.

Finally, simply plugging i3 4130 into google and you would have found this page where it again CLEARLY says 64-bit instruction set and Intel 64 - Yes.

 

Bill, I meant package boxes instead of online information.

 

The box doesn't say "Windows" either. So are you going to assume it doesn't support Windows?

You included the table for Specs where again, it clearly says "EM64T" and "Intel 64 architecture ".

That same table also includes a link to the Product page where it again, clearly shows 64-bit.

The point is, 64-bit support with modern hardware should be assumed unless it says otherwise.

 

Thanks. I think my problem has been solved, but I am still interested to know whether ARM CPUs are not among mainstream ones such as Pentium, Core and Celeron when it comes to desktop motherboards?
I saw the following question, to which no one had replied.

Plus, I personally would not call Pentium or Celeron "mainstream" for desktop motherboards. Maybe 5 - 10 year ago. But among the "Core" processors, I would call the i3, i5 and i7 CPUs mainstream among Intel CPUs.

 

In this thread, I use 'mainstream' to refer to being 64-bit instead of being popular nowadays.

Further down that page is a table in that table it states this

ntel Hyper-Threading
Intel (VT-x) virtualization
Intel VT-x including Extended Page Tables (EPT)
Intel 64 architecture
Idle condition
Intel SpeedStep
Thermal control technology

so that answers your question about being 64 bit ready/capable
