The Sandy Bridge Core i3-2357M appears to provide a noticeable performance boost compared to the first generation Core i3 CPUs noted above and an even greater advantage over AMD Fusion APUs. In the sub 12-inch category, the X121e with Sandy Bridge is going to provide one of the biggest bangs for the buck.Sony VGP-BPS13B/S

Since the Core i3-2357M is relatively new to the market, notebooks sporting the CPU are few and far between at the time of review. The Samsung NP900X1B is currently the other major 11.6-inch notebook offering the Core i3-2357M.Sony VGP-BPS13S

The graphics-benchmarks for the X121e are adequate for a netbook as well. The 3DMark Vantage scores are better than the integrated Radeon HD 6310 found in the X120e and is multiple orders of magnitude higher than the Intel GMA HD Graphics core found in many first generation Core ix netbooks.

sony vgp-bps22 Heavy gaming is still not recommended with this hardware, however, as most modern games are still relatively unplayable at low to medium settings. Of course, the X121e is not targeting gamers, so the weak 3D performance of the integrated low power Intel HD 3000 graphics should be expected.

For video playback, the processor handles 720p and 1080p videos on Youtube and 480p videos on Hulu flawlessly through its HDMI 1.4 port. Likewise, 2K resolution Youtube videos play with no stuttering, although 4K resolution videos are a slideshow. sony vgp-bps21a/b

We didn’t stop there, however, as we wanted to see how the X121e fairs with multiple and simultaneous 1080p video streams. Through a connected FullHD HDTV, a 1080p AVC1 trailer for Transformers 3 was played with multiple instances of VLC media player. sony vgp-bps21/s

Video bitrate was variable, ranging from around 5000 kb/sec to 15000 kb/sec. The notebook was able to playback two simultaneous streams with no problems, but massive frame drops occurred with three streams. The CPU usages for each stream, as shown on Windows Task Manager, are provided below.sony vgp-bps21b

sony vgp-bps21 The Lenovo X121e in this review includes a 320GB HTS723232A7A364 SATA hard drive from Hitachi with a rotational speed of 5400RPM. Results from HD Tune provided an average transfer rate of 77.6 MB/sec, which is a bit slower than the Seagate drive found in our X120e review. Regardless, the HDD speeds are still a notable improvement over the older Lenovo X100e. Of the total available space, about 10GB is reserved for the Lenovo_Recovery partition. sony vgp-bps21a

Users have the option to equip the notebook with a 128GB Lenovo RapidDrive SSD if faster speeds are a top priority. Sony VGP-BPS13

DPC Latency Checker With the DPC Latency Checker, there is a recurring high latency peak for the X121e averaging once per minute, even with all wireless radios disabled.Sony VGP-BPS13A/Q

The latency was found to be related to the Lenovo Power Manager. Once disabled, latency levels became normal at under 500 microseconds.Sony VGP-BPS13A/B

For good measure, we benchmarked the X121e with the popular PC/Mac exclusive Starcraft 2 and racing game GRID. Sony VGP-BPS13/B

For the Blizzard gameSony VGP-BPS13B/B, the short intro dialogue to the single-player challenge “For the Swarm” was used as it represents a good mix of units, dynamic Zerg creep and lava doodads. Unless low settings are acceptable, the game is near unplayable at even the preset medium settings. Multiplayer games like Starcraft are going to need the highest frame rates it can get, so don’t expect too many other modern fast-paced games to do well on the X121e, either. Sony VGP-BPS13B/Q

GRID had similar results when racing one lap around the German course with the BMW 320SI. It becomes that much more difficult to beat the AI drivers the higher the graphics settings are. Sony VGP-BPS13A/S

Slower games where trigger-happy fingers aren't required, such as Sims 3, should play adequately on the X121e.Sony VGP-BPS13/Q

While the ThinkPad X120e was all-around quiet, the same cannot be said about the X121e. Unless there is moderate background noise, the user will be able to hear the system fan even if the notebook is idle. This is not to say that the X121e would be uncomfortable to use, but the increase in fan noise compared to the X120e is definitely noticeable. Sony VGP-BPS12
