For Sandy Bridge (1155) processors
I3 2100/2105/2120/2125:
The i3 is a 32nm Dual Core processor with 2 physical cores and 2 hyperthreads effectively making it a 2 core and 4 threads processor. The 2100 runs at 3.1ghz while the 2120 runs at 3.3ghz. The 2105 has updated HD 3000 integrated graphics but is a 2100.
The I5 is a quad core processor with 4 cores and 4 threads, has no hyperthreading, but has Turbo boost 2.0 support. The lower end i5's (2300/2310/2400/2500) have locked clock multipliers, while the highend 2500k has unlocked clock multipliers.
You're correct, but you're talking about the desktop processors, he's asking about the laptop processors.
bvr37 :
The two processors are i3-2310 and i5-2410.
Both have 2 core and 4 threads.
Can u pl clarify now ?

You are correct, both have a 2C/4T config. The difference here would lie in AES-256 support and some other features (click "compare processors" on the intel site) unlocked on the i5. The difference between 2.1 GHz and 2.3 GHz would probably be noticeable in benchmarks and in CPU intensive applications only, otherwise i doubt you'd see much of a difference. But, the difference between 2.1 GHz and 2.9 GHz should be pretty obvious, and if you're running CPU intensive tasks then it should help significantly in speeding up your work. Word processing won't be able to highlight the differences well enough.
I don't know why you'd want to complicate it with bringing RAM speeds into the picture, though if in both cases the RAM's at 1333 then faster CPU clock=more performance, since both CPUs are based on the same architecture.
Also: Turbo boost kicks in as long as your processor is cool enough to support that function (and the CPU thinks it needs more power and speed). What i'm saying is, as long as the processor is within a thermal ceiling (that intel decides), it'll use more power than specified by it's TDP, and increase it's clock rate, should it (the CPU) think that it's needed. When the temperature reaches a certain point, the clock speeds will automatically drop, allowing the CPU to cool down.
