Nvidia is coming for Qualcomm’s Windows-on-ARM turf with RTX Spark, a laptop chip built around the same GB10 Grace Blackwell Superchip that powers its DGX Spark developer workstation. Qualcomm, meanwhile, has already put the Snapdragon X2 Elite Extreme into shipping laptops, which gives it the one thing Nvidia can’t fake: availability. That makes this less a spec-sheet beauty contest than a timing race, with one chip aimed at people who want Windows on ARM today and the other pitched at buyers willing to wait for a bigger hardware swing.
The comparison is messy in the way these things usually are. Qualcomm has the better near-term footing, but Nvidia shows up with a stronger software story, more memory headroom, and a far more intimidating GPU stack. In other words: one is polished enough to buy now, the other is the one that could make today’s Windows ARM laptops look a bit underdressed later.
RTX Spark brings Blackwell to Windows laptops
RTX Spark combines a custom ARM CPU developed with MediaTek, a Blackwell RTX GPU, and an AI accelerator on a single chip built on TSMC’s 3nm process with 70 billion transistors. Nvidia says it can include up to 20 CPU cores, a 6,144-core GPU, up to 128 GB of unified memory, and more than 1 petaflop of FP4 AI compute. The CPU and GPU are linked by NVLink-C2C, delivering up to 600 GB/s of bandwidth.
If that sounds a lot like Apple-style integration, that is because it is. The difference is that Nvidia has CUDA, which matters more than glossy keynote numbers in this market. It also has planned support from ASUS, Dell, HP, Lenovo, and Microsoft Surface for devices expected in autumn 2026.
Snapdragon X2 Elite Extreme is the chip you can buy first
Qualcomm’s Snapdragon X2 family arrived at Snapdragon Summit in September 2025 and is built on TSMC’s 3nm process with third-generation Oryon CPU cores. The top model, the Snapdragon X2 Elite Extreme, uses 18 cores split between 12 Prime cores and 6 Performance cores, with boosts up to 5 GHz on two cores, 53 MB of cache, and an 80 TOPS NPU. It also supports up to 48 GB of LPDDR5x memory, PCIe 5.0 storage, and up to three USB 4.0 ports.
- Snapdragon X2 Elite Extreme: 18 CPU cores, 80 TOPS NPU, up to 48 GB memory
- RTX Spark: up to 20 CPU cores, over 100 TOPS AI compute, up to 128 GB unified memory
- RTX Spark’s key edge: Blackwell GPU, CUDA, and stronger creative and gaming support
On CPU tests, Qualcomm has a real argument: it says the X2 Elite Extreme can match or beat Apple’s M4 Pro in Cinebench 2024 and Geekbench 6.3 multi-core testing, and it claims meaningful gains over the first Snapdragon X Elite. But GPU results are less flattering, and that has been the problem since Windows ARM laptops first tried to sell themselves as ”good enough” machines for everything.
GPU performance is where the gap opens
In 3DMark Steel Nomad, Qualcomm’s X2 Elite Extreme managed 1,306 points at 13 frames per second, while Apple’s M4 Pro scores around 1,620 points in the same test. That is not catastrophic, but it is not the kind of number that makes gamers or 3D artists sit up and clap. Reviewers have also run into software headaches on Windows ARM, including unsupported pro tools and games that misbehave under emulation.
Nvidia’s pitch is simpler and more dangerous: a much stronger GPU, DLSS 4.5, up to 128 GB of memory, and a mature software stack that developers already trust. If RTX Spark ships as promised, Qualcomm may find itself competing not just on benchmarks, but on whether its laptops still look like the safer buy when the heavy workloads begin.
Qualcomm still has the timing advantage
For now, Qualcomm wins the retail reality check. Snapdragon X2 laptops are already here, while RTX Spark systems are due in autumn 2026, and that delay gives Qualcomm room to sell into the mainstream Windows ARM market. Nvidia is likely aiming higher anyway: creators, AI developers, and premium buyers who would tolerate a larger bill for more memory, more GPU muscle, and fewer compromises.
The open question is whether that premium segment is big enough to matter before Qualcomm’s next move. If Nvidia can turn RTX Spark into a real shipping product on time, it could redraw expectations for Windows on ARM laptops almost overnight. If it slips, Snapdragon X2 Elite Extreme keeps the advantage simply by being there.
