CompuLab's Airtop 3 Is The Most Powerful Fan-Less Computer We've Tested Yet

The past month and a half we have been putting CompuLab's Airtop 3 computer through some demanding benchmarks and a variety of endurance workloads. With the Airtop 3 under test loaded with an 8-core / 16-thread Xeon processor, NVIDIA Quadro RTX 4000 graphics, and 64GB of RAM with NVMe SSD storage there were some concerns over thermal throttling and if this fan-less industrial PC design could really deal with the generated heat. But after all of this testing, the Airtop 3 continues running strong and another shining example of CompuLab's engineering strength.

CompuLab Turns An 8-Core/16-Thread Xeon, 64GB RAM, NVIDIA Quadro RTX 4000 Into Fan-Less Computer

Three years ago we checked out the CompuLab Airtop as a high-performance fanless PC. Back then it was exciting to passively cool an Intel Core i7 5775C, 16GB of RAM, SATA 3.0 SSD, and a GeForce GTX 950 graphics card. But now in 2019 thanks to the continued design improvements by CompuLab and ever advancing tech, their newly-launched CompuLab 3 can accommodate an eight-core / sixteen-thread Xeon CPU, 64GB of RAM, NVMe SSD storage, and a NVIDIA Quadro RTX 4000 graphics card without any fans!

The Thermal Performance Of NVIDIA's Jetson Nano $99 Developer Board

One of the exciting product launches for this month has been the introduction of the NVIDIA Jetson Nano as a $99 Arm developer board offering four Cortex-A57 cores that isn't too special itself but packing in a 128-core Maxwell NVIDIA GPU makes this board interesting for the price. Out-of-the-box the Jetson Nano is just passively cooled by a small aluminum heatsink, but does it work any better if actively cooled to avoid any potential thermal throttling? Here are some thermal benchmarks.

AMDGPU vs. Radeon Kernel Driver Performance On Linux 5.0 For AMD GCN 1.0/1.1 GPUs

A seldom advertised experimental feature of the AMDGPU kernel driver has long been the GCN 1.0/1.1 graphics support. By default these Southern Islands and Sea Islands graphics processors default to the Radeon DRM driver, but with some kernel command lime parameters can use the AMDGPU Direct Rendering Manager driver. The AMDGPU code path is better maintained since it's used for all modern Radeon GPUs, using AMDGPU opens up Vulkan driver support, and possible performance benefits. It's a while since last testing the Radeon vs. AMDGPU driver performance for these original GCN graphics cards, so here are some fresh benchmarks using the Linux 5.0 kernel and Mesa 19.1-devel.
