Intel Core i3 2120 

Released January, 2011
  • 3.3 GHz
  • Dual core
7 Out of 10

Getting the base clock up to 104MHz was enough to boost the CPU core clock speed by nearly 130MHz and running the processor at 3.43GHz did bring a nice performance boost.
by Legit Reviews (Jul, 2011)
So far we have seen that the Core i3-2120 is about 6-7% faster than the Core i3-2105 and that makes sense as the clock speed difference between the two processors is 200MHz or 6.5.

Reviews Word on the street for the Intel Core i3 2120

What People Are Saying Give it to me straight

Socket Type

Results: The Intel Core i3-2120 was slightly faster than the Core i3-2105 processor in the multi-media processor benchmark thanks to the processors 200MHz faster core clock frequency.
by Legit Reviews (Jul, 2011)
Benchmark Results: H.A.W.X. 2 was run in DirectX 10 mode on both platforms and the difference between the Intel Core i3-2105 and Core i3-2120 was very obvious.
by Legit Reviews (Jul, 2011)
Overclocking the GPU up to 1250MHz from 1100MHz helped boost our 3DMark score from 1087 3DMarks to 1301 3DMarks!

Socket

Here is a CPU-Z v1.58 screen shot of the Intel Core i3-2120 to see what we are going to be overclocking.
by Legit Reviews (Jul, 2011)
Benchmark Results: HandBrake version 0.9.5 software showed that the Intel Core i3-2120 was able to perform about 7% faster than the Intel Core i3-2105 processor thanks to the extra clock speed.
by Legit Reviews (Jul, 2011)
With two memory channels, the Core i3-2120 can support up to 32GB of DDR3 memory running at up to 1,333MHz.
by PCMag (Jan, 2012)

Multicore

If you are worried about GPU performance and play games the Intel Core i3-2105 is the better buy and well worth the extra $27 over the Core i3-2100 if that is what you are after.
by Legit Reviews (Jul, 2011)
The Intel Core i3-2120 is a very capable processor for the $149.68 price tag that online retailers are asking for it.
by Legit Reviews (Jul, 2011)
As you can see PCMark7 had the Intel Core i3-2105 and the Core i3-2120 basically tied in performance.
by Legit Reviews (Jul, 2011)

Performance

Benchmark Results: Up to this point we have only run x86 CPU benchmarks, so this will be the first GPU benchmark for these four processors.
by Legit Reviews (Jul, 2011)
It will be interesting to see if that holds true in the benchmarks.
by Legit Reviews (Jul, 2011)
Results: The entry level Intel Core i3 series of processors do not support AES-NI and neither does the AMD A-Series of APUs, so the Cryptographic Bandwidth isn't a strong point of these processors.
by Legit Reviews (Jul, 2011)

Applications

This is another reason to get this processor over the Core i3-2105 if you don't plan on doing any gaming or GPU intensive tasks as it uses less power and produces less heat.
by Legit Reviews (Jul, 2011)
This is the strongest feature of the Core i3-2120 processor and if you are planning on doing transcoding, or number crunching the Intel Core i3-2120 is the way to go as it will complete the work you are throwing at the CPU faster.
