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.

Running The Flash-Friendly File-System On A Hard Drive? Benchmarks Of F2FS On An HDD

While I have benchmarked the F2FS file-system a lot since it was mainlined back in 2013, it's all been on solid-state drives or even other forms of flash storage like USB drives. After all, F2FS is short for the Flash-Friendly File-System. But a Phoronix reader recently suggested that F2FS also works out well for traditional, rotating hard drives so I decided to run some benchmarks.

Intel Hyper Threading Performance With A Core i7 On Ubuntu 18.04 LTS

Following the news yesterday of OpenBSD disabling Intel Hyper Threading by default within its OS over security concerns and plans to disable Simultaneous Multi Threading for other processors/architectures too, here are some fresh Intel HT benchmarks albeit on Ubuntu Linux. The OpenBSD developer involved characterized HT/SMT as "doesn't necessarily have a positive effect on performance; it highly depends on the workload. In all likelihood it will actually slow down most workloads if you have a CPU with more than two cores." So here are some benchmarks using a current-generation Intel Core i7 8700K six-core processor with Hyper Threading.
