Sandybridge i5 2.3 GHz vs. 1st Gen i5 2.66 GHz

post #1 of 19
Thread Starter 
What is the difference in performance between these two CPUs?

Update: These are laptop CPUs ( i5-2410M and i5-480M )

SB will run cooler, but the first gen i5 will be faster at 2.66 vs a 2.3ghz SB

The older i5 will overclock where as the SB won't, so it will be faster. The SB chip runs cooler but the i5 isn't exactly a hot chip either. I'd personally get the first gen i5, or if you can afford it, then a i5-2500k which is worth it for the price, and not all that much more.

looking at the clock speed makes me think you are asking about laptop CPU's, am I right?
It could be helpful if you told the actual chip models

I'd go for the SB chip if the pricing is similar, performance between the two will be fairly close with the SB chip being slightly faster.

The SB i5 will win out as the architecture is FAR better. And to those of you posting about overclocking: neither of these CPUs do as they are in notebooks. tongue.gif

I left the thread open on a tab and replied after those posts were made but I hadn't refreshed so I couldn't see them, sorry.

There is about 10-15% difference clock for clock between the two architectures, so they will probably perform about even with the clock discrepancy.
