Lenovo IdeaPad Slim 5x in the test: Snapdragon X2 Plus with high performance

The Lenovo IdeaPad Slim 5x has been tested with Qualcomm’s new Snapdragon X2 Plus processor, marking a notable shift in the company's strategy for its mobile computing lineup. The device, model number 15Q8Y11, features the six-core Snapdragon X2 Plus chip, which represents the entry-level offering in Qualcomm’s 2026 Snapdragon X2 series. This marks a departure from earlier generations, where even the smallest models retained eight cores, according to reports from heise online. The test conducted by heise online revealed both strengths and weaknesses of the device. The performance of the Snapdragon X2 Plus was impressive, particularly in comparison to previous iterations of Qualcomm’s processors. However, the testing team encountered several issues, including a peculiar bug within the BIOS that affected system stability under certain conditions. Additionally, the vendor’s additional service offerings were found to be more than just promotional gimmicks, raising questions about their practical value to users. In terms of hardware specifications, the Lenovo IdeaPad Slim 5x offers a balanced configuration suitable for everyday tasks. It includes a high-resolution display, adequate RAM, and storage options that cater to both casual and moderate usage scenarios. The device is positioned as an affordable yet powerful option in the mid-range laptop market, leveraging the efficiency and performance improvements brought by the Snapdragon X2 Plus. The Snapdragon X2 series, launched in early 2026, introduces a broader range of configurations compared to its predecessor. At the top end, the Snapdragon X2 Elite Extreme X2E-94-100 boasts 18 cores, while the middle-tier model, the Snapdragon X2 Elite X2E-80-100, comes with 12 cores. The entry-level Snapdragon X2 Plus X2P-42-100 completes the lineup with a six-core design. This expansion suggests Qualcomm is aiming to provide more tailored solutions for different user segments, from power users to budget-conscious buyers. The testing process highlighted the potential of the Snapdragon X2 Plus, especially in handling multitasking and light productivity workloads efficiently. However, the presence of the BIOS bug indicates that there are still challenges to overcome in ensuring consistent reliability across all devices using this chipset. The issue reportedly manifested during prolonged use, causing unexpected shutdowns and requiring manual intervention to resolve. Consumer reactions to the Lenovo IdeaPad Slim 5x have been mixed. While some appreciate the affordability and performance balance, others remain skeptical about the long-term support and updates for the device, given the relatively new nature of the Snapdragon X2 platform. There are also concerns regarding the additional services offered by the vendor, which some users find intrusive or unnecessary. Looking ahead, the success of the Lenovo IdeaPad Slim 5x could influence future product strategies from both Lenovo and Qualcomm. If the device gains traction among consumers, it might encourage further investment in similar models, potentially expanding the Snapdragon X2 lineup. Meanwhile, addressing the BIOS bug and refining the additional services will be crucial for maintaining consumer trust and satisfaction. As the market continues to evolve, the performance and reliability of these newer chips will play a key role in shaping the landscape of portable computing.
