X100e vs. X120e - X100e has faster CPU, X120e has faster GPU

[underclocker]

As I could glean from various articles, benchmarks and forum posts, the AMD L335 dual core X100e is actually faster than the newer AMD E-350 dual core X120e. And, as expected the ATI GPU in the X120e is faster than the ATI GPU in the X100e.

I had both for a while and was able to benchmark both with the same image (Win 7 Pro 64-bit). Below are the Windows Experience scores (including the scores for Win 7 Pro 32-bit on the X100e);

X100e, 4GB RAM, L335, X25-G2 SSD, Win 7 Pro 64-bit
Processor - 4.2
Memory - 5.8
Graphics - 3.5
Gaming - 4.9
Disk - 7.5

X120e, 4GB RAM, E-350, X25-G2 SSD, Win 7 Pro 64-bit
Processor - 3.8
Memory - 5.6
Graphics - 4.1
Gaming - 5.6
Disk - 7.5

X100e, 4GB RAM, L335, X25-G2 SSD, Win 7 Pro 32-bit
Processor - 4.1
Memory - 5.5
Graphics - 3.2
Gaming - 4.4
Disk - 7.5

Could I tell the difference? No, not for general application use. However, I kept the X100e since it supports the internal, combo WiFi/WiMax adapter which I do use.

What's probably more interesting is how much faster the scores are with the 64-bit version of Windows 7. I'd say the 64-bit version does perform a little better.

It's also interesting that there is no memory performance increase for the X120e even though it switches from PC2-5300 to PC3-8500 memory.

I'd be interesting to see the X100e AMD L625 dual core scores, too. Unfortunately, I don't own all three different models!

(Notes: No issues with using the X120e image on an X100e, just use the recovery media, then run the Lenovo System Update utility. Sorry, I didn't do any battery rundown tests.)

PassMark CPU Mark Scores for X100e & X120e Processors
L335 - 851
L625 - 828
E-350 - 725
MV-40 - 385
E-240 - 323

I wanted to add to this informative post by providing the Windows 7 64bit Experience Index for the L625 dual core X100e.

X100e, L625, 4GB RAM, 60GB GSkill Sniper SSD, Windows 7 Ultimate 64-bit
Processor - 4.2
Memory - 5.7
Graphics - 3.5
Gaming - 4.9
Disk - 7.5

So, not really much difference between the two CPU's scores. I have mismatched RAM speeds so I'm not surprised to see a lower memory score.

IMHO, the X100e is a workhorse (as I'd hoped it would be). I am reinforced in this opinion by the fact that this forum is basically dead. No more posts about issues -- initially it was a few glitches at release, then some getting to know the X100e posts, and then finally some X120e stuff. This was an informative forum, thanks to everyone, about a great netbook that people are using to get things done.

Kudos Lenovo! I love mine.
