Lenovo ThinkPad X260 laptop i5-6300U 32 GB 128 GB SSD

Compact business ultrabook

The Lenovo ThinkPad X260 is a 12.5 inch ultrabook built for mobile professionals who need a lightweight Windows 10 Pro machine with a durable chassis. It ships with a dual-core Intel Core i5-6300U processor, 32 GB of DDR4 memory in a 16 GB x 2 configuration and a 128 GB SSD. The 1366 x 768 non-touch display keeps the form factor small for frequent travel.

Sustained workload behaviour

Under continuous load the i5-6300U can reach 3.0 GHz with Intel Turbo Boost Technology before thermal limits throttle the clock speed back toward the 2.4 GHz base. Integrated Intel HD Graphics 520 shares system memory, so extended graphical tasks reduce the bandwidth available to the CPU. The dual-channel 32 GB layout helps mitigate that contention during typical office multitasking.

Practical interface limits

Wi-Fi 4 caps wireless throughput well below modern router ceilings, so large file transfers over the LAN will saturate at 1000 Mbps on the RJ-45 port instead. The single HDMI output and Mini DisplayPort drive one external monitor each at 1080p, but cannot support higher refresh rates or resolutions. Three USB 3 ports provide 5 Gbps each, yet the controller shares total bandwidth across all three.
