NUMA emulation patch boosts Geekbench 6 benchmark results by up to 18% on Raspberry Pi 5

Igalia Engineer, Tvrtko Ursulin has recently submitted a patch to the Linux kernel adding a NUMA (Non-Uniform Memory Access) emulation implementation for arm64 platforms that boosts the performance of 64-bit Arm targets by “splitting the physical RAM into chunks and utilizing an allocation policy to better utilize parallelism in physical memory chip organization”.

The NUMA emulation implementation was tested on a Raspberry Pi 5 SBC and the Geekbench 6 single-core score improved by 6%, while the multi-core score boosted by 18% after splitting into four emulated NUMA nodes. In other words, that’s like having a Broadcom BCM2712 CPU overclocked from 2.4 GHz up to 2.83 GHz.

Olimex NEO6502 is a W65C02 and Raspberry Pi RP2040-powered retro computer with HDMI, USB, and more

Olimex has recently launched NEO6502 an open-source hardware retro computer designed for educational and entertainment purposes, but that doesn’t mean it can’t be used for retro gaming. The board is very unique as it’s built around a 65C02 MPU and Raspberry Pi Pico RP2040 MCU in a dual-processor configuration. The MOS6502 handles the Apple II, Oric, and Commodore 64 emulators whereas the RP2040 handles everything else including HDMI (DVI) video output using the PicoDVI project. Previously we have written about similar retro computer kits such as the CERBERUS 2100, TinyLlama x86, DevTerm with ClockworkPi v3.14, Olimex AgonLight2, and many others feel free to check those out if you are interested in retro tech with a modern twist.

NDAA-compliant NVIDIA Jetson Orin NX and Nano bundles target drones

ARK Electronics has recently introduced NDAA-complaint NVIDIA Jetson Orin NX and Nano bundles designed for drones with the company’s Jetson PAB (Pixhawk Autopilot Bus) carrier board, an ARKV6X flight controller, and an SSD preloaded with NVIDIA Jetpack and the ARK UI. I’ve come across the board following a post on X pointing to an article on Tom’s Hardware about the US passing a bill called “Countering CCP Drones Act” that would effectively ban DJI drones in the US. DJI is supposed to have a 90% market share of the U.S. hobby market, a 70% market share of the industrial market, and an over 80% market share of the first responder market, so not everybody will be happy if the bill passes in the senate and becomes enacted by the US president. But US companies making NDAA-compliant hardware and drones may bit mind, and that’s how I discovered ARK Electronics NVIDIA […]
