Classified as a productivity laptop, the HP ProBook 455 G10 15.6″ measures 359 × 233 × 19 mm with a volume of 1589.293 cm³ and weighs 1,737 g. It includes a backlit keyboard and comes with a 3-year warranty, which is notable for a device in this category. The laptop does not use a fanless design, nor does it offer weather sealing or a rugged build, placing it firmly in the standard office-use segment rather than field or harsh-environment deployment.
The display is a 15.6″ IPS LCD panel with LED backlighting, running at a resolution of 1920 x 1080 px and a pixel density of 141 ppi. Brightness sits at a typical 250 nits, and the refresh rate is 60Hz — standard for a productivity-focused machine. The screen includes an anti-reflection coating, which helps reduce glare during indoor use, though it does not support touch input.
The processor runs eight cores at a base clock of 2 GHz with a turbo frequency of 4.5 GHz, supporting 16 threads and multithreading for handling concurrent workloads. Built on a 7 nm process and operating as a 64-bit CPU, it pairs with 32GB of DDR4 RAM — expandable up to 64GB across two memory channels. Storage is handled by a 1TB NVMe SSD connected via PCIe 3.0, offering fast read and write performance for everyday tasks. The integrated GPU has a base clock of 300 MHz and a turbo of 2000 MHz, with DirectX 12 support, though XeSS (XMX) is not available on this configuration.
In Geekbench 6, the HP ProBook 455 G10 15.6″ scores 6277 in the multi-core test and 1633 in the single-core test, reflecting the processor's capacity for parallelized workloads relative to its single-thread throughput. The PassMark overall score of 18042 indicates solid general-purpose performance, while the single-threaded PassMark result of 3006 gives a more focused view of per-core responsiveness for tasks that rely on sequential processing.
The HP ProBook 455 G10 15.6″ offers a practical wired port selection, including three USB-A 3.2 Gen 1 ports, one USB-C 3.2 Gen 1 port, one HDMI 2.1 output, and one RJ45 Ethernet port. There are no USB 3.2 Gen 2, USB 4, Thunderbolt, DisplayPort, mini DisplayPort, or VGA connections, and no external memory card slot is present. On the wireless side, the laptop supports Wi-Fi 6E (802.11ax) along with backward-compatible Wi-Fi 6, 5, and 4 standards, and uses Bluetooth 5.3. AirPlay is also supported, while a VGA connector is absent from the port lineup.
The HP ProBook 455 G10 15.6″ includes stereo speakers, a 3.5 mm headset jack, a front camera, a single microphone, and a fingerprint scanner for biometric login. It does not support 3D facial recognition, voice commands, or a stylus. On the audio side, Dolby Atmos and S/PDIF output are absent. The device also lacks motion and location sensors — there is no gyroscope, accelerometer, compass, or GPS — and it does not include an optical disc drive. Graphics-related features such as ray tracing and DLSS are not supported, reflecting the integrated GPU's focus on general productivity rather than rendering workloads.
The CPU is a laptop-class processor with a clock multiplier of 20, a TDP of 15W, and a maximum operating temperature of 95 °C. It supports a range of instruction sets including MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2, and carries an NX bit for hardware-level security. The multiplier is locked and the chip does not use big.LITTLE architecture. It features a three-level cache hierarchy — 512 KB L1, 4 MB L2 (0.5 MB/core), and 16 MB L3 (2 MB/core) — and operates across two memory channels with support for ECC memory and a maximum RAM speed of 4267 MHz. The integrated Radeon Vega 8 GPU comprises 8 execution units, 512 shading units, 32 TMUs, and 8 ROPs, backed by 10,700 million transistors, and supports OpenCL 2.2 and OpenGL 4.6. The overclocked PassMark result is recorded at 19,844.
