Difference between i5 versions significant?

#1 Post by ElectricKaibutsu » Thu Feb 28, 2019 8:13 pm

Hi everyone,

I've been doing a lot of research and have decided that my first ThinkPad will be an X230. I have decided on an i5 model since I don't think I need the extra power from the i7, but I'm not sure what i5 model I should get, or if it even matters.

According to ThinkWiki, there are two different i5 models available for the X230:

Intel Core i5-3360M (2.80 GHz, 3MB L3, 1600MHz FSB)
Intel Core i5-3320M (2.60 GHz, 3MB L3, 1600MHz FSB)

Does anyone have any experience with both? Is the difference in speed noticeable? Does the i5-3360M model use more power/drain the battery faster? Or are they not different enough to matter and I shouldn't worry about it while I scour ebay and craigslist for deals?

Had a X230 with the 3360 and have a X230T with a 3320 and I didn't even know they have difference processors until I checked.

Wouldn't worry about it. The Gigahertz difference really only comes into play In synthetic tests.

The efficiency of two screens equally sized with equal numbers if pixels are equal. The time spent by a 4:3 user complaining about 16:9 is proportional to the inefficiency working with a 16:9 display, therefore the amount of useful work extracted is equal.

Nice! That was exactly the kind of insight I was hoping for. Thanks!

The general rule of thumb: most users would only notice it if CPU speed difference is 10% or more (given that all else remain the same).
Daily Driver: X1 Extreme 1st Gen (X1E1): i7 | 16GB | 1TB | IPS
Current Thinkpads: X1E1 | X1C4 | X1C3 | X250 | X230 | T410
Retired Thinkpads: T42 | 560 (circa 1996)

And UserBenchmark only rates the 3360 at 6% faster than the 3320.
