Nvidia has officially confirmed that two successor chips to its RTX Spark platform are already in active development, signaling the company's long-term commitment to consumer Arm-based processors. At Computex 2026 in Taipei, CEO Jensen Huang revealed the internal codenames N2X and N3X while also opening the door to a gaming handheld variant, a product category Nvidia has never formally entered.

What Are N2X and N3X, and When Will They Arrive?

The N2X and N3X chips represent Nvidia's roadmap for the next two generations of its consumer Arm-based lineup, following the current RTX Spark platform, internally called N1X. However, Huang deliberately withheld specifications, release windows, and pricing details for both chips. This measured approach reflects Nvidia's positioning of RTX Spark not as a gaming-focused product, but as a persistent local artificial intelligence (AI) companion system that happens to run games well.

Huang framed the early confirmation as a statement of intent rather than a product announcement, comparing the commitment to a long-running product line rather than a one-off experiment. He told Tom's Guide that Nvidia intends to "expand our family" of consumer Arm chips for years. The company's public messaging so far has focused entirely on N1X, which began reaching partner devices earlier in 2026.

What Specs Does the Current RTX Spark Chip Deliver?

To understand where N2X and N3X might head, it helps to know what RTX Spark currently offers. The N1X chip, sold under the RTX Spark name, packs up to 20 Arm CPU cores alongside a Blackwell-generation GPU with roughly 6,144 CUDA (Compute Unified Device Architecture) cores. CUDA cores are the parallel processing units that handle graphics and AI computations. The chip pairs with as much as 128 gigabytes of unified LPDDR5X memory running at around 300 gigabytes per second of bandwidth.

Nvidia has claimed the chip can hit 100 frames per second at 1440p resolution in current games, though that figure comes from the company's own marketing rather than independent lab testing. A smaller companion variant called N1 also exists, aimed at lower-cost or more compact machines. Microsoft's Surface Laptop Ultra and several Asus systems already ship with RTX Spark silicon inside, positioning it as a mainstream AI PC chip rather than a gaming niche product.

How Does Nvidia's Consumer Chip Roadmap Compare?

• N1 Status: Currently shipping in compact, lower-cost mini PCs with reduced core and memory configurations compared to N1X
• N1X (RTX Spark) Status: Currently shipping in laptops, mini PCs, and AI PCs with up to 20 Arm cores, approximately 6,144 CUDA cores, and up to 128GB LPDDR5X memory
• N2X Status: Confirmed in development with no specifications, target devices, or release timeline disclosed
• N3X Status: Confirmed in development with no specifications, target devices, or release timeline disclosed
• Handheld Variant Status: Unconfirmed and rumored only; Nvidia says it would work with an original equipment manufacturer (OEM) partner if one wanted to build a gaming handheld, with no internal commitment made

Why Is Nvidia Suddenly Interested in Gaming Handhelds?

Until this week, Nvidia's involvement in handheld gaming ran through Nintendo. Custom Tegra chips power the Switch and Switch 2, but those are closed, first-party designs Nvidia does not sell to outside PC makers. A Windows-compatible RTX Spark derivative would be a genuinely new product category for the company, competing directly for the same OEM design wins that Intel and AMD currently split between them.

The timing is significant. Intel just unveiled its own dedicated handheld chips, the Arc G3 and Arc G3 Extreme, built specifically to challenge AMD's Ryzen Z2 Extreme in the fast-growing handheld gaming PC category. AMD's Ryzen Z2 Extreme currently powers most premium handhelds on shelves today, built around eight cores split between three full Zen 5 cores and five efficiency-focused Zen 5c cores, paired with a 16-compute-unit Radeon GPU.

Asked directly about a handheld version of RTX Spark, Huang stopped short of committing Nvidia to building one. He told Tom's Guide that if a hardware partner wanted to build a handheld around the chip, Nvidia would "work with them on it," a response that effectively makes OEM appetite the limiting factor rather than technical readiness.

What Technical Barriers Could Block an RTX Handheld?

Performance and pricing are not the only obstacles. Huang and Nvidia's own briefings flagged anti-cheat software compatibility as a real, unresolved challenge for scaling gaming on Arm-based architecture. Most competitive multiplayer titles rely on kernel-level anti-cheat systems built and certified for x86 processors. Getting major publishers to validate those systems on an entirely different instruction set is a slow, publisher-by-publisher process that Nvidia does not fully control.

Valve has already run into a version of this problem with SteamOS and its own Steam Deck hardware, where certain anti-cheat-protected titles remain unsupported years after the original Steam Deck's launch. Nvidia entering with an Arm-based chip, rather than the x86 designs AMD and Intel both use, would restart that compatibility clock from closer to zero.

How Does Huang View RTX Spark's Long-Term Role?

Huang's most memorable framing from the Computex interview was not about raw specifications at all. He described RTX Spark as closer to "R2-D2" than a laptop CPU, an image meant to convey a small, semi-autonomous, always-on companion device rather than a component buried inside a case. That distinction matters for how Nvidia wants the platform understood. RTX Spark is being pitched less as a gaming chip and more as a persistent local AI system, one that happens to also run games well.

Huang also described RTX Spark buyers as people who will keep these systems "in their homes for 5 to 10 years," comparing them to home theater equipment bought once and used for a decade. This suggests Nvidia is building a slow-moving platform rather than rushing annual refreshes. The early confirmation of N2X and N3X reinforces that vision, signaling to partners and consumers alike that Nvidia is committed to this product category for the long haul.
