Core i3: 2310 vs 380

[stay_ahead]

Looking for advice on the differences between the following laptop Core i3 CPU's.

i3 2310 - 2.1 GHz
i3 380 - 2.53 GHz

I know the 2310 is a Sandybridge chip but what is performance gap given the difference in clock speed? What does the 2310 give me that the 380 doesnt? Also how is integrated GPU on the 2310 compared to basic mobility Radeon 4200?

Thanks for any advice you can provide.

I would imagine from other Benchmarks I've seen that a newer Sandybridge i3 @ 2.1Ghz would be about the same speed as an older i3 @ 2.5Ghz, although I haven't come across either processor in anything I've personally read. I assume both are mobile processors also due to the low speeds?

As for the integrated graphics I'm not sure they will be capable of much, although since it's a laptop I'd imagine it will play HD video content but be pretty rubbish for gaming.

Yes that's correct, both are mobile CPU's.

I'm looking at a Lenovo with the 380 vs Packard Bell with 2310. Both are similar price. I normally buy AMD systems but I guess an Athlon II P340 won't compete on performance with these i3's? And considering Athlon II systems appear to be no cheaper than i3's, it's hard to justify paying the same price.

AFAIK,the mobile Sandy Bridge CPUs have the HD3000 IGP which means it trades blows with an HD5450 graphics card:

They'd be essentially the same performance-wise but as CAT-THE-FIFTH says, the Sandy Bridge chip has a better IGP. If you're getting a separate GPU then this doesn't matter and the i3-380 should be cheaper.

Quite a few only have HD2000 I think:

EDIT: You're right I think...

The major difference between mobile Sandy Bridge and its desktop countpart is all mobile SB launch SKUs have two graphics cores (12 EUs), while only some desktop parts have 12 EUs (it looks like the high-end K SKUs will have it). The base GPU clock is lower but it can turbo up to 1.3GHz, higher than most desktop Sandy Bridge CPUs. Note that the GPU we tested in Friday's preview had 6 EUs, so mobile Sandy Bridge should be noticeably quicker as long as we don't run into memory bandwidth issues.
