What is PVTM? Or why your Rockchip RK3588 CPU may not reach 2.4 GHz

While the Rockchip RK3588 processor is advertised as reaching 2.4 GHz, not all RK3588 chips may achieve this frequency. The keyword is PVTM (Process-Voltage-Temperature Monitor), and we’ll try to explain why it does, and why some of the RK3588 processors may only be clocked at about 2.3 GHz, while others will run fine at 2.4 GHz. This all started with Rock 5B SBC debug party, where we noticed our boards did not reach the same frequency. Willy Tarreau noted the “pvtm” value was different between our boards: Willy’s board: (Cortex-A76 cluster 1 @ 2,304 MHz, cluster 2 @ 2,352 MHz)

UP 4000 SBC is a Raspberry Pi lookalike with an Intel Apollo Lake processor

AAEON has unveiled the UP 4000 single board computer with a form factor and ports arrangement similar to Raspberry Pi 2/3, but powered by a choice of x86 processors, namely the Intel Atom E3900 series, Celeron N3350, or Pentium N4200 all parts of the Apollo Lake family. The first UP Board was introduced in 2015 as a device offering an x86 alternative to the Raspberry Pi 2 with an Intel Atom x5-Z8300/Z8350 “Cherry Trail” processor, but later “UP bridge the gap” boards from the company used larger “Squared” (85.6 x 90 mm) or “Xtreme” (122 x 120 mm) form factors. The UP 4000 SBC brings us back to the original business card form factor but with a boost in performance and various specifications improvements. UP 4000 vs UP Board specifications AAEON says the new board is able to deliver 30% faster CPU performance and twice the 3D graphics performance […]

ROCK 5B developer edition preview – Part 1: Unboxing and first boot to Debian 11

Radxa ROCK5 Model B (aka ROCK 5B) is one of the most anticipated Rockchip RK3588 single board computers due to its features set and relatively affordable price. It was first showcased in January, but it’s taking a while as the Cortex-A76/A55 SoC is a complex beast. The good news is that the public launch is getting closer as Radxa sent “developer edition” samples to developers and enthusiasts for a “debug party”. I was one of the recipients so, in this post, I’ll have a closer look at the latest revision of the board, and give it a quick try first before going into more details in the second of this preview. ROCK5 Model B unboxing I received the 16GB RAM version which should be the same for all board part of the “developer edition batch. Developers are invited to submit reports to Radxa forums, and since those are public, anybody […]
