Thanks to its 1.6-GHz Intel fourth-generation Core i5-4200U processor, 8GB of RAM and 256GB LITE-ON SSD, our configuration of the ThinkPad T440s offered very strong performance that was good enough for demanding productivity work. On PCMark 7, a synthetic benchmark that measures overall performance, the T440s scored an impressive 4,970, well above the 3,445 thin-and-light laptop category average, the Toshiba Tecra Z40’s mark of 2,524 and the T431s’ 2,884 score.
With its speedy 256GB SSD, the T440s booted Windows 8 in just 14 seconds, half the 28.4-second category average and a bit less than the ThinkPad T431s (16 seconds). The drive took just 27 seconds to complete the LAPTOP File Transfer test, which involves copying 4.97GB of mixed media files. That’s a rate of 188.5 MBps, more than triple the 57.9 MBps category average and eight times the Tecra Z40 and its 7,200-rpm hard drive. The 13-inch MacBook Pro with Retina Display notched a more impressive 299.4 MBps performing the same test in OS X Mavericks.
The ThinkPad T440s took just 5 minutes and 14 seconds to complete the OpenOffice Spreadsheet Macro Test, where we match 20,000 names with their addresses. That time is more than a minute faster than the 6:21 category average, but almost 30 seconds slower than the Tecra Z40 and its 1.9-GHz Core i5-4300U CPU.
The T440s’ integrated Intel HD 4400 graphics chip achieved a modest score of 930 on 3DMark11, a leading synthetic graphics benchmark. That’s a little below the 962 category average, but well above the Toshiba Tecra Z40 (869) and ThinkPad T431s (530).
When we fired up “World of Warcraft” at the T440s’ 1920 x 1080 native resolution, the system achieved a not-quite-playable frame rate of 29 fps, which dropped to just 15 fps when we turned up the special effects. Both rates are well below the 66 and 29.9 fps category averages.
