Intel's Serpent Lake: The Leaked 2028 APU That Packs an Nvidia RTX GPU

A wave of leaks is painting a picture of one of the most significant chip collaborations in recent PC history: a new processor from Intel with an integrated Nvidia RTX GPU. Codenamed "Serpent Lake," this system-on-a-chip is rumored to target a Q1 2028 launch, with a potential reveal at CES 2028 . It represents a major strategic shift for Intel, which would be abandoning its in-house Arc integrated graphics for a competitor's technology to create a high-performance part aimed squarely at gaming laptops, compact PCs, and the handheld market .

While neither company has officially confirmed the chip's existence, the volume of reports from hardware leakers and tech journalists provides a consistent, if unverified, set of specifications. The most crucial detail, the partnership itself, was publicly confirmed by Intel and Nvidia in September 2025, when they announced plans for Intel to build and sell x86 SoCs featuring Nvidia RTX GPU chiplets .

A Titan Lake Spin-Off with an Nvidia Heart

Serpent Lake is not a standalone generation but is described as a special spin-off branch of Intel's future Titan Lake CPU family . The chip's design will adopt a chiplet or SoC architecture similar to AMD's "Halo" series (like the upcoming Strix Halo), meaning it will combine multiple silicon tiles in a single package .

The headline feature is the dedicated Nvidia RTX GPU tile. This is not a simple licensing deal; it's the integration of physical Nvidia GPU chiplets directly into an Intel processor package for the first time . Given the 2028 target, reports consistently suggest this tile will be based on Nvidia's next-generation Rubin GPU architecture, or a potential successor like Rubin-Next . One report mentions the Rubin architecture's third-generation Transformer Engine, suggesting significant AI performance improvements of up to 50% over its predecessor .

Next-Gen CPU Cores: Copper Shark and Golden Eagle

The leak has also pulled back the curtain on Intel's next-generation CPU core architectures for both performance and efficiency:

• P-Core (Performance Core): Codenamed "Copper Shark", this is reportedly the new microarchitecture that will power the high-performance cores in Serpent Lake .
• E-Core (Efficiency Core): The efficiency cores are expected to use the "Golden Eagle" architecture .

These codenames suggest that despite some past rumors, Intel will continue with a hybrid architecture of separate performance and efficiency cores for this chip family .

Manufacturing and Memory: A Cutting-Edge Package

To deliver on the promise of high-end gaming and content creation, the Serpent Lake package will likely rely on advanced manufacturing and memory technologies.

• GPU Tile Fabrication: The Nvidia RTX GPU tile is widely reported to be manufactured on TSMC's N3P process node, a cutting-edge 3nm-class technology, or a future successor node . The manufacturing process for Intel's own CPU tile has not been mentioned in leaks.
• Memory Subsystem: Feeding a powerful integrated GPU requires enormous memory bandwidth. A detailed analysis suggests Serpent Lake will support a massive 16-channel LPDDR6 memory subsystem to meet this demand, which would be a significant upgrade to allow the integrated GPU to perform like a discrete graphics card .

A Direct Shot at AMD's Halo Series

The competitive intent behind Serpent Lake is clear. Multiple sources state the chip is being designed to compete directly with AMD's high-end "Halo" series APUs, which offer powerful integrated graphics in a compact form factor for premium laptops and mini-PCs . By combining Intel's CPU expertise with Nvidia's market-leading GPU technology, the partnership creates a product that could redefine the expectations for integrated graphics performance. The rumored $5 billion strategic investment in Intel by Nvidia, reportedly sealed by former Intel CEO Pat Gelsinger and Nvidia CEO Jensen Huang in 2025, underscores the high stakes of this collaboration .

Important caveat: Every specification, codename, and timeline mentioned here is based on leaks and unverified reports. Intel and Nvidia have not officially announced a product called "Serpent Lake," nor have they confirmed any of its technical details. As with all early hardware leaks, plans and specifications can change before a product reaches the market.
