Fresh leaks have revealed specifications for the upcoming Redmi K90 Ultra, showcasing how Xiaomi plans to differentiate this third member of the K90 family from the already-announced K90 Pro Max . While the K90 and K90 Pro Max launched last month, the Ultra variant appears to be targeting a different segment with its MediaTek chipset and gaming-focused features .
⚡ Key Leak Details
The Redmi K90 Ultra has been spotted in certification listings and rumors, revealing a device that makes different trade-offs compared to the Pro Max model. Rather than simply being a superior version, the Ultra appears to be optimized for specific use cases, particularly gaming and battery life .
The Chipset Divide: MediaTek vs Qualcomm
One of the most significant differences lies in the processor choice. While the K90 Pro Max uses the Qualcomm Snapdragon 8 Elite Gen 5, the K90 Ultra is rumored to feature the upcoming MediaTek Dimensity 9500+ chipset . This represents a strategic differentiation rather than a simple hierarchy.
The Dimensity 9500+ is expected to be an upgraded variant of MediaTek's flagship processor, likely launching in the first half of 2026 to keep the chipset competitive . While Qualcomm processors traditionally have better gaming and emulation performance, MediaTek's offering could provide compelling value .

Display and Design Differences
The K90 Ultra is rumored to feature a 6.8-inch LTPS OLED display with "1.5K" resolution and an impressive 165Hz refresh rate, surpassing the Pro Max's 120Hz capability . The device will reportedly have very rounded corners, following current design trends, and will maintain premium construction with a metal frame .
Both devices are expected to include ultrasonic in-display fingerprint scanners and solid water resistance ratings, though exact IP ratings for the Ultra remain unspecified . The Pro Max features IP68 certification, making it dust-tight and waterproof up to 1.5 meters for 30 minutes .
Battery and Charging Capabilities
One area where the K90 Ultra may significantly outperform the Pro Max is battery capacity. Leaks suggest the Ultra will house a battery "close to 8000mAh" , while the Pro Max features a 7560mAh silicon-carbon battery .
The Pro Max supports 100W wired charging and 50W wireless charging , but wireless charging capabilities for the Ultra remain unconfirmed in current leaks. This could be a differentiating factor favoring the Pro Max for users who value charging flexibility.
💡 Understanding Redmi's "Ultra" Naming
In the Chinese market, "Ultra" models often serve as flagship-killers rather than outright superior versions. As one commenter noted, "The K80 Ultra is known in China as Redmi K80 Extreme Edition and most specs are top notch except for the cameras which are weak. And the price is pretty low for what it offers" . This suggests the K90 Ultra may follow a similar pattern of offering powerful core specifications while potentially compromising in areas like camera performance to maintain an aggressive price point.
Market Positioning and Global Availability
The Redmi K90 Ultra's specifications position it as a compelling option for users who prioritize raw performance, smooth display performance, and battery life over comprehensive camera capabilities . This strategic differentiation allows Xiaomi to target multiple segments within the flagship space without cannibalizing sales.
Based on Xiaomi's past patterns, the Redmi K90 Ultra may eventually reach global markets under the POCO branding. Recent POCO F8 series launches have closely mirrored Redmi K90 specifications , suggesting the Ultra could follow a similar path, potentially as a POCO F8 variant in early 2026 .
Early Verdict: Which Should You Wait For?
For gamers and performance enthusiasts, the K90 Ultra's 165Hz display and potentially more affordable pricing could make it the more compelling option, provided camera performance isn't the highest priority. The Dimensity 9500+ should deliver flagship-level performance while possibly undercutting Qualcomm on price.
For users wanting a complete flagship experience with no compromises, the K90 Pro Max remains the safer choice with its proven Snapdragon 8 Elite Gen 5, advanced camera system featuring a 5x telephoto lens , and wireless charging support. The Pro Max's camera system represents a significant upgrade, featuring a 50MP primary sensor with a large 1/1.31-inch optical format and 13.5 EV dynamic range .
As more details emerge about the K90 Ultra's complete specification sheet and pricing, the value proposition will become clearer. Currently, it appears Xiaomi is creating distinct flagship tiers rather than a simple linear hierarchy, giving consumers more targeted options based on their specific needs and priorities.
