In late 2012 and 2013 the Intel Core i3 was a nice CPU for entry level systems. Dual-core systems were sufficient for most users that didn't play games or used high-end applications like video editting or 3D-modelling. Even most games didn't benefit from having more 2 cores at that time.
The 3220 runs at 3.3GHz and has hyper-threading capabilities. > Read more
An entry-level CPU in 2012/2013 that floats just a little bit under the Core i3: depending on the model you have differences in clock-frequency (although you can have 3.3GHz in both Core i3 and Pentium Dual-Core for instance). The only 'big' difference is that the Pentium Dual-Core doesn't feature Hyper-Threading.
Another difference is the somewhat weird naming convention. Intel uses G2020 for 2.9GHz and G2030 for 3GHz. Logic dictates that the 3.1GHz part would be dubbed G2040, however, Intel decided to name is G2120. As far as I can see the G21xx and the G20xx have identical specs as far as integrated graphics, memory support and features goes.
To make things worse: the G2120 and 2120T have the same numerical name, yet the T stands for power optimized (or Thermal optimized?) processor which makes it less power hungry. However, the CPU runs 400MHz slower than the G2120 'vanilla' version. Why use the same numerical identification for a slower product? > Read more
This CPU is still in it's original (and unopened) box. It sits there since 2015 and probably many years to come.
The E5-2430v2 was launched in early 2014 for use in dual socket systems. It was not the fastest CPU or the one with most cores but it's price-performance ratio was generally pretty good (depending on your use-case of course).
For reference: with the Ivy Bridge core Intel also had 15-core parts available or 6-core parts that run at 3.7 GHz. Ivy Bridge came in many configurations and price ranges. On this page on Wikipedia shows an extensive list of all available server CPU's with the Ivy Bridge core. > Read more
This is a mobile CPU for the embedded market. It's soldered onto a motherboard that has been made for a specific purpose (a ONYX ZEUS medical PC). The motherboard resembles a notebook motherboard with high integration of parts and few upgrade options.
The i7 3555LE has two cores with HT running at 2.5GHz and can turbo up to 3.2GHz. This makes is a fine performer within the Ivy Bridge architecture. > Read more
