The Dell Inspiron 16 Plus 7640 has a physical footprint of 356mm wide by 250mm deep, with a 16mm thickness and a total volume of 1,424 cm³, keeping its overall bulk reasonably contained for a 16-inch machine. It weighs 1,900 grams and does not use a fanless design, meaning active cooling is present. The keyboard includes backlighting, while the chassis carries no weather-sealing or splashproof protection. Dell covers the laptop with a 1-year warranty.
The laptop features a 16-inch screen with a 2560x1600 resolution at 188ppi, delivering a reasonably sharp image across its panel. The display runs at a 120Hz refresh rate and offers a 1200:1 contrast ratio alongside 300 nits of typical brightness. An anti-reflection coating is applied to the surface, though the panel does not support touch input. The system is capable of driving up to four external displays simultaneously.
The processor runs across 14 cores — six performance cores at 1.4GHz and eight efficiency cores at 0.9GHz — totaling 22 threads, with a turbo clock that reaches 4.8GHz; notably, hardware-level multithreading is not supported. The chip is built on a 7nm process, supports 64-bit operation, and connects to storage via a PCIe 5 interface. Storage consists of a 1024GB NVMe SSD, and the system carries 16GB of DDR5 RAM running at 6400MHz across two memory slots, with 16GB also representing the maximum supported memory capacity. The integrated GPU has a base clock of 300MHz and a turbo of 2250MHz, with support for DirectX 12 Ultimate.
In PassMark testing, the system achieves a multi-core score of 24,879, reflecting the combined throughput of its 14-core processor across all available threads. The single-core result of 3,468 indicates the per-core processing capability of the CPU in lightly threaded workloads.
The laptop includes one Thunderbolt 4 port and one USB 4 40Gbps port for high-speed connectivity, alongside two USB 3.2 Gen 1 Type-A ports for standard peripherals; there are no USB 3.2 Gen 2 ports, no DisplayPort or mini DisplayPort outputs, and no RJ45 ethernet port. Video output is handled through a single HDMI 1.4 port, and a Type-C connector is present on the chassis. Wireless connectivity covers Wi-Fi 6E, Wi-Fi 6, Wi-Fi 5, and Wi-Fi 4 standards, and the machine also supports AirPlay. An external memory card slot is included, rounding out the available connectivity options.
The laptop supports sleep-and-charge USB ports, allowing connected devices to be charged even when the system is powered off or in sleep mode. It does not use a MagSafe power adapter.
Audio is handled through stereo speakers with Dolby Atmos support, and a 3.5mm headset jack is available for wired headphones or headsets; there is no S/PDIF output. The laptop has a front-facing 2.07MP camera paired with a dual-microphone setup, though it lacks 3D facial recognition, a fingerprint scanner, and voice command support. No stylus is included in the box. The device does not feature a gyroscope, accelerometer, compass, or GPS, and there is no optical disc drive.
The CPU uses a BGA 2049 socket, operates with a clock multiplier of 38, and has a thermal design power of 28W, with a maximum rated temperature of 110°C; the multiplier is locked. It employs big.LITTLE technology to distribute workloads across its core types, supports the NX bit for hardware-level security, and carries a 24MB L3 cache. Supported instruction sets include MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2. Memory runs across two channels with a maximum supported speed of 7467MHz, though ECC memory is not supported. The integrated Intel Arc Xe-LPG 128EU GPU features 1,024 shading units, 64 texture mapping units, 32 ROPs, and 8 execution units, with OpenCL 3 and OpenGL 4.6 support. The overclocked PassMark result is recorded at 24,880.
