Microsoft is set to release the Surface Laptop Ultra, the flagship model in its RTX Spark series, with two different configurations tailored to different user needs. The first version will include a full RTX Spark chip, featuring 20 CPU cores and 6,144 CUDA cores on the GPU. This model will be available with 32, 48, 64, or 128 GB of unified memory, making it suitable for users interested in running local large language models. The 128 GB version, in particular, is expected to handle models with up to 120 billion parameters, which is significant for advanced AI research and development. The second configuration will use a modified RTX Spark chip, referred to as "castrated," with 18 CPU cores and 5,120 CUDA cores on the GPU. This version will come with 24 or 32 GB of unified memory, making it more suitable for gamers and content creators. While it lacks the power of the full chip for handling large AI models, it should provide strong performance for typical gaming and multimedia tasks. The Surface Laptop Ultra will feature a 15-inch "PixelSense Ultra" touchscreen with a high pixel density of 262 pixels per inch and an HDR peak brightness of 2,000 cd/m². This display is designed to deliver sharp visuals and vibrant colors, ideal for both professional and entertainment use. The laptop's chassis will be less than 18 mm thick, emphasizing portability without compromising on performance. In terms of connectivity, the device will include three USB-C ports, one USB-A port, an HDMI output, a headphone jack, and an SD card reader. These ports provide flexibility for various peripherals and external displays. Additionally, the Surface Laptop Ultra is expected to have excellent battery life, maintaining 99.6% of its performance once the charger is disconnected, ensuring long usage times without frequent recharging.
