Libre RISC-V Snags $50k EUR Grant To Work On Its RISC-V 3D GPU Chip

The very ambitious project working on an open-source RISC-V architecture to serve as a Vulkan accelerator for 3D graphics secured a minor victory last week with receiving $50k EUR from the European Commission's Next Generation Internet initiative. They will be using these funds to allow for full-time engineering work and bounty-style tasks to work on this "100% libre RISC-V + 3D GPU chip for mobile devices."

ClearFog ARM Workstation Speed Even More Compelling But Now Called HoneyComb LX2K

ClearFog was the name for that 16-core mini-ITX workstation development board/platform that we've been eager to learn more about with its $500~750 USD price point, extensive networking connections, M.2, SATA, socketed DDR4 memory support, and other features we've been long desiring to see out of an affordable yet powerful ARM workstation. It turns out that dream board is being renamed to the HoneyComb LX2K and its performance is increasingly competitive with AMD/Intel x86 enthusiast offerings.

Spectre/Meltdown/L1TF/MDS Mitigation Costs On An Intel Dual Core + HT Laptop

Following the recent desktop CPU benchmarks and server CPU benchmarks following the MDS/ZombieLoad mitigations coming to light and looking at the overall performance cost to mitigating these current CPU vulnerabilities, there was some speculation by some in the community that the older dual-core CPUs with Hyper Threading would be particularly hard hit. Here are some benchmarks of a Lenovo ThinkPad with Core i7 Broadwell CPU looking at those mitigation costs.
