The HP Omen Slim 16 (2025) is a gaming laptop with a 19mm thin profile and dimensions of 357mm wide by 269mm deep, giving it a total volume of roughly 1,824.6 cm³. It weighs 2,420g and relies on an active cooling system rather than a fanless design. The chassis is not ruggedized and does not carry a weather-sealed or splashproof rating, though it does include a backlit keyboard as a standard feature.
The Omen Slim 16 (2025) features a 16″ IPS LCD panel with LED backlighting, delivering a resolution of 1920x1200 pixels at a pixel density of 141 ppi. It operates at a 144Hz refresh rate and includes an anti-reflection coating to reduce glare, though it does not support touch input. The system can drive up to four displays simultaneously, making it capable of supporting an expanded multi-monitor setup.
The Omen Slim 16 (2025) is equipped with 32GB of DDR5 RAM running at 4800MHz across two slots, with a maximum supported capacity of 64GB, paired with a 1TB NVMe SSD for flash-based storage. The CPU runs at speeds of 6 cores at 2GHz and 8 cores at 1.5GHz, reaching a turbo frequency of 5.1GHz across 16 threads with multithreading enabled, and the processor connects to the rest of the system via a PCIe 4.0 interface. On the graphics side, the GPU operates at a base clock of 952MHz with a boost up to 1455MHz, backed by 8GB of GDDR7 VRAM and delivering 9.684 TFLOPS of floating-point performance alongside a texture rate of 151.3 GTexels/s and a pixel rate of 46.56 GPixel/s; it is built on a 5nm process and supports DirectX 12 Ultimate and 64-bit computing, though it does not include XeSS support.
In PassMark testing, the Omen Slim 16 (2025) achieves a multi-core score of 30,756, reflecting the combined throughput of its CPU across all available threads, while the single-core result of 4,373 indicates the processor's per-core performance in lightly threaded workloads.
The Omen Slim 16 (2025) offers a practical set of wired and wireless connectivity options. On the wired side, it includes three USB 3.2 Gen 2 Type-A ports and one USB 3.2 Gen 2 Type-C port, one HDMI output, and one RJ45 Ethernet port, while there are no USB 2.0, DisplayPort, mini DisplayPort, VGA, Thunderbolt 3 or 4, or USB 4 ports of any kind. There is also no external memory card slot. Wireless connectivity is handled via Wi-Fi 6 (802.11ax) with backwards compatibility for Wi-Fi 5 and Wi-Fi 4, and the system supports AirPlay.
The Omen Slim 16 (2025) supports sleep-and-charge USB ports, allowing connected devices to be charged even when the laptop is in a sleep state, and it does not use a MagSafe power adapter.
The Omen Slim 16 (2025) includes stereo speakers, a 3.5mm headset jack, and a single built-in microphone for audio input and output, though it lacks Dolby Atmos and an S/PDIF port. A front-facing camera is present, but the laptop does not offer a fingerprint scanner, 3D facial recognition, or voice command support. On the graphics feature side, it supports both ray tracing and DLSS, catering to demanding rendering workloads. The system does not include a stylus, optical disc drive, or any motion and location sensors such as a gyroscope, accelerometer, compass, or GPS.
The CPU in the Omen Slim 16 (2025) is a laptop-class processor using a BGA 2049 socket with a clock multiplier of 20, a maximum operating temperature of 110°C, a 45W TDP, and a 24MB L3 cache; it employs big.LITTLE technology, supports instruction sets including MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2, carries an NX bit for hardware-level security, includes integrated graphics, and has a dual-channel memory configuration supporting RAM speeds up to 8400MHz, though its multiplier is locked. The dedicated GPU is built on the Blackwell architecture and features 3,328 shading units, 104 texture mapping units, 32 ROPs, and 8 execution units, running its memory at 1750MHz with an effective speed of 28,000MHz across a 128-bit bus for a peak bandwidth of 448 GB/s; it supports Intel Resizable BAR, stereoscopic 3D, multi-display output, double precision floating point, ECC memory, OpenCL 3.0, and OpenGL 4.6, and is built from approximately 21,900 million transistors, while LHR is not present. An integrated Arc 140T GPU is also included alongside the discrete unit, and the system posts a PassMark overclocked score of 30,494.
