Xiaomi has officially confirmed another important detail about the hardware of the upcoming Redmi K90 Ultra . This high-performance flagship, exclusive to China, will feature a 165Hz gaming display with a peak brightness of up to 3500 nits , making it one of the most powerful Redmi gaming phones to date. The device will go on sale in China on June 30 at 7:00 PM , and unlike many previous Redmi K Ultra models, this device is expected to be permanently exclusive to China , with no plans for a global release.
A screen designed for gaming with a high refresh rate
The official Redmi poster confirms that the Redmi K90 Ultra uses M10 luminescent material , a 165Hz e-sports display , and Xiaomi’s Green Mountain eye protection technology . The display also supports native 165fps optimization in over 40 games , meaning certain titles can run at ultra-high frame rates without relying solely on frame interpolation.
This is important for competitive mobile gaming, as a higher refresh rate can improve motion clarity, touch response, and overall gameplay smoothness. Combined with proper game optimization, the Redmi K90 Ultra positions itself as a device designed for gamers seeking stable performance with high frame rates, rather than occasional performance spikes in benchmark tests.
According to previous official announcements, the phone also boasts all the gaming DNA of the Redmi K90 Max. Lu Weibing confirmed that the Redmi K90 Ultra includes the dedicated D2 gaming display chip , e-sports-level touch tuning, game-centric sound effects, landscape network optimization, and the same active cooling system. This makes the device more than just a standard flagship phone with a fast chipset; it’s a performance package designed around gaming stability.

How hardware improves the real-life gaming experience
The Redmi K90 Ultra combines three key elements of a gaming-focused phone: a high refresh rate display, a powerful chipset, and efficient thermal management. The 165Hz display enhances visual fluidity, while the D2 gaming display chip helps manage the visual workload of games and optimize the frame rate. The Snapdragon 8 Elite delivers flagship-level processing power, but it’s Xiaomi’s active cooling system that allows the phone to maintain peak performance for longer periods.
Xiaomi claims that the Redmi K90 Ultra uses the same air cooling system as the Redmi K90 Max. This includes a large fan, which they say is 6% larger than typical solutions , a vortex airflow channel designed to reduce turbulence, and an operating noise level of around 32 dB . The company also claims that the phone can reduce its temperature by up to 10°C in 100 seconds .
This is important because games with high refresh rates generate a lot of heat. Without proper cooling, even the fastest chipset will see its performance drop after just a few minutes. By combining a 165Hz display with active cooling, Xiaomi aims to maintain stable frame rates during extended gaming sessions.
The Redmi K90 Ultra is designed specifically for the Chinese market of high-performance phones, where users expect top-tier gaming features at more competitive prices. Xiaomi is clearly positioning this model as a direct response to gamers who want top-level performance without having to move up to a more expensive, ultra-premium category.
The fact that it’s only available in China also gives the device greater strategic importance. Rather than being a direct global model, the Redmi K90 Ultra appears to be designed for the highly competitive Chinese gaming phone segment, where brands vie fiercely on cooling, screen quality, sustained performance, and value for money. For Xiaomi fans worldwide, this means the Redmi K90 Ultra should be considered a high-performance project exclusive to China, rather than a phone awaiting an international launch.
