Der Qualcomm Snapdragon X Elite X1E-78-100 ist ein mobiler Prozessor für Notebooks. Er integriert erstmals die von Nuvia stammenden Oryon CPU-Kerne. Diese 12 (3 Cluster zu 4 Kernen) Kerne takten mit bis zu 3,4 GHz (kein höherer Dual-Core Boost wie bei den stärkeren Modellen) und nutzen den ARM v8.7 Befehlssatz. Die CPU-Leistung hängt stark vom eingesetzten TDP ein. Dieser kann von bis zu 80 Watt eingestellt werden.
Die Leistung der CPU-Kerne scheint bei angepasster Software hervorragend zu sein. Die Single-Core Performance im Cinebench 2024 kann mit den schnellsten Kernen von Apple (M3) und Intel mithalten bzw. diese sogar überholen. Unter Windows hat die CPU jedoch immer einen Nachteil bei nicht angepasster Software, da diese emuliert werden muss. Besonder Spiele sind hier stark betroffen, die oft nicht vernünftig laufen.
Zusätzlich zum CPU-Teil, integriert der X Elite eine starke NPU mit bis zu 45 TOPS für AI-Beschleunigung.
Die integrierte Grafikkarte ist etwas älter und unterstützt kein vollständiges DirectX 12 Ultimate (nur 12_1, jedoch inklusive Raytracing). Mit nur 3,8 TFLOPS bietet die GPU deutlich weniger Maximalleistung als in den Topmodellen (z.B. 4,6 TFLOPS im X1E-84-100).
Trotz der fehlenden Effizienzkerne, soll der Snapdragon X Elite laut Qualcomm sehr effizient sein. Der Chip wird im 4nm Prozess bei TSMC produziert. In unseren Tests ist die Effizienz etwas höher als bei den aktuellen Intel und AMD Modellen, aber leicht hinter Apple (M3).
Qualcomm Snapdragon X Plus X1P-42-100

The Snapdragon X Plus X1P-42-100 is a relatively affordable ARM architecture processor (SoC) for use in Windows laptops that is set to debut on June 4, 2024. The X1P-42-100 is thought to have 8 Oryon CPU cores (8 P-cores, 0 E-cores) running at a not yet known clock speed of at least 3.0 GHz. As far as other key features are concerned, the X Plus probably comes with the same 3.8 TFLOPS Adreno GPU, 45 TOPS Hexagon NPU and LPDDR5x-8448 memory controller that its bigger and smarter brother, the X1P-64-100, has.
Architecture and Features
Qualcomm Oryon cores are said to be based on the ARM v8.7 microarchitecture. Much like modern AMD and Intel processors, the Snapdragon chip is compatible with USB 4 and thus with Thunderbolt 4; it remains to be seen if the X Plus is compatible with GeForce or Radeon discrete graphics cards.
The Qualcomm SoC is said to have 8 PCIe 4 and 4 PCIe 3 lanes for connecting various kinds of devices. NVMe SSDs are supported with a throughput of up to 7.9 GB/s; the RAM controller may or may not be compatible with RAM as fast as 8448 MT/s. A 45 TOPS NPU for accelerating AI workloads is most likely included.
This X Plus chip does not make use of the same die that the X1P-64-100, X1E-78-100, X1E-80-100, X1E-84-100 are based on.
Performance
If the official performance data is any indication, the X Plus should be a whole lot slower than the 9-core Apple M4 in multi-thread workloads while being a lot more power-hungry. We'll make sure to update this section once we have in-house testing results.
Like any other Windows on ARM platform, the Snapdragon X chip works best with applications and games compiled specifically for ARM processors, of which there aren't many for the time being.
Graphics
The integrated Adreno GPU is supposed to be DirectX 12-compatible (not DirectX 12 Ultimate-compatible; as the rumors have it, there is no ray tracing of any kind here). It is also expected to deliver up to 3.8 TFLOPS of performance. For reference, the slowest professional Nvidia Ada Generation graphics card for laptops, the RTX 500 Ada, delivers up to 9.2 TFLOPS.
The Qualcomm iGPU will let you use up to 3 UHD 2160p monitors simultaneously. 2160p120 integrated displays are supported, as are the popular AV1, HEVC and AVC video codecs (both decoding and encoding).
Power consumption
The X1P-42-100 is most likely going to be less power-hungry than its more powerful X Elite brothers. Expect to see anything between 10 W and 35 W under long-term workloads because that's what Ryzen U chips normally consume.
The SoC is built with a 4 nm TSMC process for decent, as of H1 2024, energy efficiency.
