Short answer: NVIDIA RTX Spark is the company’s first processor built specifically for Windows PCs, and it starts shipping in October 2026. It combines an Arm-based Grace CPU with a Blackwell RTX GPU in one chip, with up to 20 CPU cores, 6,144 GPU cores, 128 GB of unified memory, and up to 1 petaflop of AI performance. Laptops will come from ASUS, Dell, HP, Lenovo, Microsoft, and MSI. NVIDIA has not announced official prices yet; analyst estimates put the flagship 128 GB configuration around $2,899 and entry models near $1,799.
NVIDIA has spent thirty years putting graphics chips inside other companies’ computers. RTX Spark is the moment it steps onto the main stage of the PC itself. For the first time, NVIDIA is selling its own complete processor for Windows laptops and desktops, going head to head with Intel, AMD, Qualcomm, and Apple. Here is what is confirmed, what is still estimated, and what it means for anyone shopping for an AI laptop this fall.
What Is NVIDIA RTX Spark?
RTX Spark is a new class of AI PCs powered by the RTX Spark Superchip. The idea is simple: fuse NVIDIA’s RTX graphics and its AI acceleration into a single processor that runs Windows 11, so a slim laptop can run large AI models, creative workloads, and games locally without leaning on the cloud.
The chip pairs a Grace CPU (NVIDIA’s Arm-based server CPU design, adapted for PCs) with a Blackwell RTX GPU. On the AI side, the full NVIDIA CUDA stack runs natively, which matters because CUDA is the software platform most of the world’s AI is built on. In practice, that means developers can prototype, fine-tune, and run inference on AI models on the same machine they carry around.
Before NVIDIA’s official announcement, this chip was known only through leaks as “N1” and “N1X.” Those were internal codenames. The public name is now RTX Spark Superchip, and NVIDIA has not used the N1X label in its official materials.
Confirmed Specs From NVIDIA
The following specifications come directly from NVIDIA’s official RTX Spark product page, so these are the numbers you can trust:
- CPU: up to 20-core NVIDIA Grace (Arm-based)
- GPU: up to 6,144-core NVIDIA Blackwell RTX GPU
- AI performance: up to 1 petaflop (FP4)
- Memory: up to 128 GB unified LPDDR5X
- Power: 45 to 80 W in laptops; a 140 W desktop configuration also exists
- OS: Windows 11
- Graphics features: DLSS 5, NVIDIA Reflex 2, 4th-generation ray tracing cores, 5th-generation Tensor cores, G-SYNC, DirectX 12 Ultimate
- Media: 9th-generation NVIDIA encoder, 6th-generation decoder, 4:2:2 hardware encode and decode, AV1 support
NVIDIA lists two laptop configurations: the flagship with the 6,144-core GPU, 20-core CPU, and up to 128 GB of memory, and a second tier with a 5,120-core GPU, 18-core CPU, and up to 64 GB. Compact desktop PCs use the top configuration with up to 128 GB.
Why the Unified Memory Matters
The 128 GB of unified memory is the spec that makes RTX Spark genuinely different from a typical thin laptop. Unified memory is shared between the CPU and GPU, so a large AI model can sit in memory where the GPU can reach it directly. That is what makes it realistic to run large language models and AI agents entirely on the device. As AI workloads like Google’s Gemini keep growing, the ability to run serious models locally instead of paying for cloud API calls is a big deal for developers and creators.
Release Date: When Can You Buy One?
NVIDIA announced RTX Spark at Computex 2026, and in early September 2026 the company confirmed that RTX Spark laptops and compact desktops would begin shipping worldwide in October 2026. No exact calendar date has been announced, and NVIDIA is leaving the precise launch timing to its manufacturing partners.
On NVIDIA’s own product page, the call to action is still “sign up to be notified when RTX Spark Laptops and Desktops are available,” which suggests the rollout is happening in waves through the OEM partners rather than a single global launch day.
Which Companies Are Making RTX Spark PCs?
Six launch partners are confirmed: ASUS, Dell, HP, Lenovo, Microsoft, and MSI. Reports indicate Acer and Gigabyte will follow with RTX Spark designs later.
Microsoft is the most interesting partner here. Its lead products include a Surface Laptop Ultra with a 15-inch mini-LED display reaching 2,000 nits of peak brightness, plus a Surface RTX Spark Dev Box aimed at developers. When the company behind Windows ships its own flagship hardware on a new chip platform, that is a strong signal about where the ecosystem is headed.
RTX Spark Price: What We Know
NVIDIA has not published official retail prices for RTX Spark laptops or desktops. Until the OEMs list final prices, everything below is an estimate, and you should treat it that way:
- Flagship 128 GB configuration: Morgan Stanley analysts estimated roughly $2,899
- Lower-memory models: estimated around $1,799 and up
- Separately, Tom’s Guide published a speculative estimate of $1,999 to $2,499 for a lower-tier configuration
The closest real price reference is NVIDIA’s sibling product, DGX Spark, a complete AI developer workstation that sells for $3,999. But DGX Spark is a different product entirely: it is an NVIDIA-branded desktop running DGX OS, while RTX Spark is a chip platform that ships inside Windows 11 PCs built by partners.
At those estimates, RTX Spark launches as a premium halo product for creators and AI developers, not a mainstream laptop. The ~$1,799 tier is where the real volume battle will be fought against Qualcomm’s Snapdragon X machines and Apple’s MacBook Air.
RTX Spark vs the Competition
Against Qualcomm Snapdragon X
Qualcomm was first to the modern Windows-on-Arm party with Snapdragon X Elite and X Plus. RTX Spark answers with far more GPU muscle: up to 6,144 CUDA cores and 1 petaflop of AI compute is in a different league from Qualcomm’s integrated graphics, and 128 GB of unified memory dwarfs what Snapdragon laptops offer. Qualcomm’s likely response is aggressive pricing or a refreshed chip before RTX Spark reaches shelves in volume.
Against Apple Silicon
Apple’s Mac lineup proved that Arm laptops can be fast and efficient, and the MacBook Pro remains the benchmark for creative professionals. RTX Spark is the first credible Windows-native challenger with a comparable unified-memory story: up to 128 GB on the NVIDIA side versus Apple’s high-memory configurations. NVIDIA also has the CUDA ecosystem advantage for AI developers, since most AI tooling targets CUDA first. Apple’s strengths remain battery life, the mature macOS software base, and its integrated hardware-software design.
Against Intel and AMD
For the x86 incumbents, RTX Spark is the threat they have been dreading: NVIDIA’s brand, CUDA ecosystem, and AI credibility arriving in a laptop processor. Intel and AMD still own software compatibility and the enterprise channel, and their latest chips are strong. But if Windows on Arm finally delivers the performance that makes compatibility a non-issue, the x86 duopoly loses its main defensive moat.
The Big Question: Will Your Software Run?
RTX Spark runs Windows 11 on Arm, and that raises the compatibility question every Windows-on-Arm machine faces. Microsoft’s Prism emulator runs most existing x86 applications, and major developers including Adobe are building native ARM64 versions of their apps. Historically, compatibility has been the weak point of Windows on Arm, especially for games with strict anti-cheat software.
NVIDIA’s official page advertises the full gaming stack: ray tracing, the complete DLSS suite, NVIDIA Reflex, and G-SYNC, plus over 1,000 RTX-accelerated apps and games. But x86 games will run through emulation, and independent benchmarks have not been published yet. If you are buying primarily for gaming, wait for third-party reviews before deciding.
Should You Wait for an RTX Spark Laptop?
RTX Spark makes the most sense for three kinds of buyers:
- AI developers: native CUDA, up to 128 GB of unified memory, and 1 petaflop of AI compute in a portable machine is genuinely new for Windows.
- Creators: the full NVIDIA Studio stack, 4:2:2 hardware encode, AV1, and strong GPU performance in a thin chassis.
- Early adopters who want a Windows alternative to the MacBook Pro for AI and creative work.
It makes less sense if you need guaranteed compatibility with niche x86 software, play competitive games with kernel-level anti-cheat, or want a budget machine. And with official prices still unannounced, the value equation is incomplete. The smart move for most buyers: wait for the first independent reviews and final OEM pricing, expected as the October 2026 shipments land.
The bigger story is structural. Whether or not you buy one, RTX Spark marks the moment the AI boom arrived in the laptop aisle. As AI agents and on-device models become central to how people work, a reflection of the shift already visible in tools like the AI assistants compared in our Claude vs ChatGPT breakdown, the PC is being reinvented around local AI compute. NVIDIA just made the boldest move yet.
