Getting information about CPU

You can check the model no by executing
cat /proc/cpuinfo | grep 'model name' | uniq
Output:
model name : Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz
To Count number of CPUs:
cat /proc/cpuinfo | grep processor
Output :
2
To check the number of cores !
cat /proc/cpuinfo | grep 'core id'
core id : 0
core id : 1
$hardinfo | less
$nproc / prints out the number of processing units
For Windows Users Use CPU-Z here

I am new to the world of Linux and Ubuntu. I want say get maximum information about CPU. (cpufreq , no. of cores, no. of threads per core, instruction set, size of caches, instruction set, virtualization etc.)
I would prefer a method which works on all Linux distributions over Ubuntu specific approaches.
lscpu
seems to give only few info, I especially miss the model name here:Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 4 On-line CPU(s) list: 0-3 Thread(s) per core: 2 Core(s) per socket: 2 Socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 69 Stepping: 1 CPU MHz: 989.531 BogoMIPS: 4788.74 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 3072K NUMA node0 CPU(s): 0-3
Running
sudo lscpu
returns same.
