Qualcomm Snapdragon X Plus (X1P-66-100) vs Qualcomm Snapdragon X Elite (X1E-78-100): Full Comparison
Introduction
Qualcomm’s Snapdragon X series represents a significant step in computing, bringing Arm-based architecture with a focus on AI and power efficiency to Windows laptops. Within this series, the Snapdragon X Plus and Snapdragon X Elite offer different performance tiers. This comparison focuses on the specific X1P-66-100 (Plus) and X1E-78-100 (Elite) SKUs, breaking down their specifications and intended use cases. Understanding their differences can help clarify which platform might be found in various device segments.
CPU and Performance
The most fundamental difference lies in the central processing unit (CPU) configuration. Both platforms use Qualcomm’s custom Oryon cores, but the number of these high-performance cores varies.
- Snapdragon X Plus (X1P-66-100): This variant is equipped with a 10-core CPU. It typically consists of a configuration where all cores are performance-oriented, but at a specified clock speed for this SKU.
- Snapdragon X Elite (X1E-78-100): This variant features a 12-core CPU. The additional cores generally provide higher multi-threaded performance, which can be beneficial for tasks like video editing, coding, and handling multiple demanding applications simultaneously.
Both chips share the same architectural foundation, meaning single-core performance and core efficiency are closely related. The Elite model’s higher core count is its primary performance differentiator.
GPU and Graphics
Graphics performance is handled by the integrated Qualcomm Adreno GPU. For these specific SKUs:
- Snapdragon X Plus (X1P-66-100): Features a GPU with a maximum clock speed of 3.8 Teraflops.
- Snapdragon X Elite (X1E-78-100): Features a more powerful GPU configuration capable of up to 4.6 Teraflops.
This difference suggests that the Elite variant will generally offer better performance in graphics-intensive applications, including casual gaming, photo editing, and UI rendering. Both GPUs support modern APIs and are designed for efficient performance in thin-and-light laptop form factors.
AI and NPU
Artificial intelligence acceleration is a central pillar of the Snapdragon X series. In this aspect, the two platforms are identical.
- Both the Snapdragon X Plus (X1P-66-100) and Snapdragon X Elite (X1E-78-100) integrate the same Hexagon NPU (Neural Processing Unit).
- This NPU is rated for a performance of 45 TOPS (Trillions of Operations Per Second).
This parity means that for AI-driven tasks—such as live translation, advanced background blur in video calls, or creative suite assistants—both platforms are expected to deliver a similar level of performance and capability.
Connectivity and Platform Features
The two platforms share an identical suite of connectivity and modern platform features, which includes:
- 5G Modem: Integrated Snapdragon X65 5G Modem-RF system.
- Wi-Fi & Bluetooth: Support for Wi-Fi 7 and Bluetooth 5.4.
- Memory Support: Both support LPDDR5x memory, with the X Elite typically paired with higher maximum capacities in system designs.
- Display Support: Capable of driving multiple external displays at high resolutions.
- Process Node: Manufactured on a 4nm process technology for power efficiency.
The shared feature set ensures that devices built on either platform will offer modern connectivity, which is a key advantage for mobile computing.
