Qualcomm Snapdragon X Elite X1E-84-100 vs Apple M2 Pro 10-Core

Qualcomm Snapdragon X Elite X1E-84-100

The Snapdragon X Elite X1E-84-100 is a pretty fast ARM architecture processor (SoC) for use in Windows laptops. The X1E-84-100 is the fastest member of the Snapdragon X series, as of May 2024; as such, it has 12 Oryon CPU cores (3 clusters of equally powerful cores; 12 threads) running at up to 4.2 GHz, along with the 4.6 TFLOPS Adreno X1-85 GPU, the 45 TOPS Hexagon NPU and an impressively fast LPDDR5x-8448 memory controller.

Two slower Snapdragon X Elite flavors exist, known as the X1E-80-100 and X1E-78-100. In the meantime, the X1E-00-1DE is a special version of the X1E-84-100 aimed at system makers and software developers that has just slightly higher single-core and dual-core Boost clock speed of 4.3 GHz but otherwise the same CPU/GPU/NPU configuration.

Architecture and Features

Qualcomm Oryon cores are in part based on Nuvia IP; they most likely make use of 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 but it remains to be seen if the X Elite is compatible with GeForce or Radeon discrete graphics cards.

The Qualcomm SoC is believed to have at least 12 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; furthermore, most laptops built around the chip are expected to have 16 GB of LPDDR5X-8448 RAM. There is also a 45 TOPS NPU for accelerating AI workloads.

Performance

When all of the 12 cores are under load, they run at up to 3.8 GHz. The 4.2 GHz clock speed is only achievable under single-thread or dual-thread loads.

Taking the difference in clock speeds into consideration, its multi-thread performance should be around 12% higher than that of the X Elite X1E-78-100 for AMD Ryzen 7 8845HS-like performance in most real-world tasks. We'll make sure to update this section once we get our hands on a laptop powered by the X1E-84-100.

Like any other Windows on ARM platform, the Snapdragon X chip works best with applications and games compiled specifically for ARM processors. If making use of the built-in x86 to ARM emulation mode, a performance penalty of about 20% is to be expected.

Graphics

The integrated 4.6 TFLOPS X1-85 GPU is DirectX 12-enabled but not DirectX 12 Ultimate-enabled, despite featuring VRS and ray tracing support. The 4.6 TFLOPS of performance that it supposedly delivers represent a half of what the slowest current-generation professional Nvidia Ada graphics card for laptops, the RTX 500 Ada, is capable of.

Its gaming performance is set to be just slightly better than that of the Radeon 780M. That should be sufficient for about 30 fps in Baldur's Gate 3, a triple-A title released in 2023, at 1080p / Low. Slightly older games will run just fine with most settings set to Medium.

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). The hardware does not support the VVC codec; that feature remains a Lunar Lake exclusive for now.

Power consumption

As the most powerful Snapdragon X Elite chip, the X1E-84-100 can eat up to 80 watts depending on the system and the power profile chosen. This will differ from one laptop to another, with most designs expected to target the 40 W sweet spot.

The SoC is built with a 4 nm TSMC process for decent, as of H1 2024, energy efficiency.

Apple M2 Pro 10-Core

The Apple M2 Pro 10-Core is a System on a Chip (SoC) from Apple that is found in the early 2023 MacBook Pro 14 and Mac Mini entry level models. It offers 10 of the 12 cores available in the chip divided in six performance cores (P-cores) and four power-efficiency cores (E-cores). The E-cores clock with up to 3.4 GHz, the P-Cores up to 3.7 GHz (mostly 3.3 GHz in multi-threaded workloads and 3.4 GHz in single threaded).

The big cores (codename Avalanche) offer 192 KB instruction cache, 128 KB data cache, and 36 MB shared L2 cache (up from 24 MB in the M1 Pro). The four efficiency cores (codename Blizzard) are a lot smaller and offer only 128 KB instruction cache, 64 KB data cache, and 4 MB shared cache. CPU and GPU can both use the 24 MB SLC (System Level Cache). 

The unified memory (16 or 32 GB LPDDR5-6400) next to the chip is connected by a 256 Bit memory controller (200 GB/s bandwidth) and can be used by the GPU and CPU.

The performance of the M2 Pro 10-Core should be similar to the old M1 Pro with all 10 cores. The multi-threaded performance should be slower, as the M2 10-core has two p-cores less (and 2 e-cores more) but the single-threaded performance should be better due to the faster clock speed and architectural improvements. The old M1 Pro 8-core should be noticeably slower.

The integrated graphics card in the M1 Pro 10-core offers all 16 of the 19 cores.

Furthermore, the SoC integrates a fast 16 core neural engine (faster than M1 Pro), a secure enclave (e.g., for encryption), a unified memory architecture, Thunderbolt 4 controller, an ISP, and media de- and encoders (including ProRes).

The M2 Pro is manufactured in 5 nm at TSMC (second generation) and integrates 40 billion transistors.
