The Thunderobot Zero 18 Radiant is a gaming laptop with a footprint of 408 x 300 mm and a thickness of 30 mm, resulting in a total volume of 3672 cm³. It tips the scales at 2800 g, which is consistent with its large-format, desktop-replacement positioning. The chassis is not weather-sealed or ruggedized, and it does not use a fanless cooling approach. On the usability side, the laptop includes a backlit keyboard and ships with a one-year warranty.
The laptop features an 18″ IPS LCD panel with LED backlighting, rendering content at 2560 x 1600 px for a pixel density of 167 ppi. With a 240Hz refresh rate and a contrast ratio of 1800:1, the display is well-suited for fast-paced gaming content, while a typical brightness of 500 nits provides adequate output in a variety of lighting conditions. The screen does not include a touch layer or an anti-reflection coating, and the system supports up to four simultaneous displays in total.
The processor runs 24 threads across two cluster configurations — 8 cores at 2.7 GHz and 16 cores at 2.1 GHz — with a turbo frequency of 5.4 GHz, multithreading enabled, and 64-bit support throughout. The system ships with 64GB of DDR5 RAM, expandable to a maximum of 192GB, paired with 2TB of NVMe flash storage over a PCIe 5.0 interface. On the graphics side, the GPU operates at a base clock of 990 MHz, boosting to 1515 MHz, and is equipped with 24GB of GDDR7 VRAM, delivering 31.8 TFLOPS of floating-point performance alongside a texture rate of 496.9 GTexels/s and a pixel rate of 193.9 GPixel/s. The GPU is manufactured on a 4 nm process and supports DirectX 12 Ultimate, though XeSS is not available on this configuration.
In CPU benchmark testing, the laptop achieves a PassMark multi-core score of 56,426, reflecting the combined throughput of its 24-thread processor configuration, while the single-core PassMark result of 4,723 indicates the per-core performance available for workloads that rely on single-threaded execution.
The laptop's wired port selection includes two USB 3.2 Gen 2 Type-A ports, two USB 3.2 Gen 1 Type-A ports, one USB 4 40Gbps port, and a single RJ45 Ethernet jack for wired networking, while video output is handled by one HDMI 2.1 port — there are no DisplayPort, mini DisplayPort, or VGA outputs. The machine does not include any Thunderbolt 3 or Thunderbolt 4 ports, nor any USB 3.2 Gen 2 or Gen 1 Type-C ports beyond the USB 4 connection, and there are no USB 2.0 ports. Wireless connectivity covers Wi-Fi 6 (802.11ax) with backwards compatibility for Wi-Fi 5 and Wi-Fi 4, alongside Bluetooth 5.3. An external memory slot and AirPlay support are also present, while a VGA connector is not included.
The laptop is equipped with a 99 Wh battery and supports sleep-and-charge functionality, allowing connected USB devices to be charged even when the system is powered off or in sleep mode. A MagSafe power adapter is not part of the configuration.
For audio, the laptop includes stereo speakers and a 3.5 mm headset jack, though Dolby Atmos and an S/PDIF output are not available; a single built-in microphone handles voice capture. A 2MP front camera is present, while fingerprint scanning, 3D facial recognition, and voice commands are not supported. On the graphics side, the GPU supports both ray tracing and DLSS, expanding rendering options for compatible titles. Sensor-wise, the laptop does not include a gyroscope, accelerometer, compass, or GPS, and there is no optical disc drive or stylus included in the package.
The CPU is a laptop-class processor mounted on a BGA 2114 socket with a 95W TDP, a clock multiplier of 27, an unlocked multiplier, and Turbo Boost version 2, with a maximum rated temperature of 105 °C. It employs big.LITTLE technology, includes integrated graphics, and supports a broad instruction set covering MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2, along with NX bit for hardware-level security. Cache allocation stands at 36 MB for L3 and 40 MB for L2, while the dual-channel memory subsystem supports a maximum RAM speed of 6400 MHz and ECC memory. The Blackwell-architecture GPU features 10,496 shading units, 328 TMUs, and 128 ROPs across a 256-bit memory bus, reaching an effective memory speed of 25,400 MHz and a peak bandwidth of 811.5 GB/s; LHR is not present. The system supports Intel Resizable BAR, stereoscopic 3D, multi-display output, OpenCL 3, OpenGL 4.6, and Double Precision Floating Point, and the GPU memory runs at a base speed of 2000 MHz.
