Under maximum load, the surface temperature above the keyboard increased to 41.1 degrees Celsius, which felt noticeably warm.
The frequency varied between 2.5GHz and 3.4GHz, with occasional peaks up to 3.6GHz, surpassing the rated maximum of 3.4GHz. Although we did not observe any performance degradation in full power mode, it’s important to note that the Snapdragon X Elite’s power consumption under maximum load is notably higher than anticipated.
As Qualcomm’s first PC chipset featuring the new Oryon cores, we expect that the next iteration of Snapdragon X Elite will focus on improving efficiency, aiming to align with the efficiency levels of Apple’s M-series chipsets.
Geekbench 6 GPU
To evaluate the integrated Adreno X1 GPU on the X Elite, we conducted the Geekbench GPU test using OpenCL and Vulkan APIs. Under the OpenCL API, the Adreno X1 GPU scored 20,543 points while plugged in and 20,417 points on battery. It performed better with the Vulkan API, achieving 23,635 points on power and 24,227 points on battery.
The Adreno X1 GPU in this Snapdragon X Elite SKU (X1E-78-100) operates at 1.25GHz. While the GPU’s performance is decent for light gaming, it falls short compared to competitors, such as the 8-core Apple M2 GPU, which scores over 24,000 points in the Geekbench OpenCL test.
Although the Adreno X1 GPU is adequate for light gaming, it lags behind in performance compared to other options, and improvements in software and driver optimization are needed to enhance gaming performance.
3DMark
The Adreno X1 GPU in the Snapdragon X Elite supports Microsoft’s DirectX 12 API, enabling you to play games like Cyberpunk 2077 on low settings. We tested it with the 3DMark Wild Life Extreme benchmark using the DX12 API, where it achieved 37.82 FPS and 6,316 points while plugged in.
In the 3DMark Solar Bay test using the Vulkan API, the GPU performed reasonably well, scoring 10,239 points and 42.81 FPS in Solar Bay Section 1. However, Intel GPUs in the same test typically achieve around 49 FPS and over 11,000 points. In summary, while the Adreno X1 GPU is competent, it falls short compared to integrated GPUs from Intel, AMD, and Apple.
Geekbench ML
To evaluate the AI capabilities of the Snapdragon X Elite chipset, we ran the Geekbench ML test. Using the ONNX DirectML API with the GPU, it scored 2,350 points, and with the ONNX CPU API, it achieved an inference score of 2,885 points—all while plugged in. Note that NPU support for the X Elite has not yet been integrated into Geekbench ML.
In comparison, Apple’s M3 chipset scores over 4,000 points with its Core ML CPU API and around 7,800 points for AI inference using the M3 GPU. This suggests that the Snapdragon X Elite underperforms in AI tasks compared to Apple’s M3 chipsets.
