I was absolutely blown away earlier this year by Qualcomm's Snapdragon X2 platform after spending a month with Lenovo's Slim 7x (Gen 11). The System-on-Chip (SoC) was fast and efficient on or off the charger, and it came in a sleek 14-inch package.
A new commissioned study from the independent testing group Signal65 has basically confirmed my arguments, this time after testing the flagship X2 Elite Extreme (X2E-96-100) variant in retail systems you or I can buy.
