UCIe (Universal Chiplet Interconnect Express) open standard for Chiplets with heterogeneous chips

UCIe Open Chiplet platform-on-a-package

We first heard about Chiplet, chips that gather IP or chips from different vendors into a single chip, in 2020 with the now-defunct zGlue’s Open Chiplet Initiative, but the term recently came back to the forefront last month with Intel’s investment into the “Open Chiplet Platform” that aims to offer a modular approach to chip design through chiplets with each block/chiplet customized for a particular function. It turns out there’s now an official standard called the Universal Chiplet Interconnect Express (UCIe) whose specification defines the interconnect between chiplets within a package, and not only backed by Intel, but also AMD, Arm, ASE, Google Cloud, Meta, Microsoft, Qualcomm, Samsung, and TSMC. UCIe defines the Physical Layer (Die-to-Die I/O) and protocols to be used for the chiplet interfaces, currently PCIe and CXL (Compute Express Link), but more protocols will be added to the specification in the future. The goal is to provide […]

Year 2021 in review – Top 10 posts and statistics

As per tradition, we’ll look back at what happened during the year in the last post, and see what 2022 may have in store, plus the usual statistics from CNX Software website. The biggest story of 2021 has to be the worsening of semiconductors shortages with extremely long lead times, prices of some components going up multiple folds, constant complaints on Twitter about availability and prices. I think I even saw a website, hopefully misconfigured, showing an estimated availability of a specific STM32 MCU in 2037. This also gave rise to opportunities and board redesigns, with MotorComm Ethernet chips replacing some Realtek chips in SBCs such as NanoPi R2C and  Orange Pi R1S Plus LTS, and CH9102F showing up as a replacement for CP2104 in some IoT boards. We also got some interesting Arm processors, but sadly the high-expected Rockchip RK3588 got delayed by another year, although it’s getting really […]

OS and Memory Impact on Mini PC Gaming Performance

This article looks at what the effect of running a different operating system or having more memory has on similarly spec’d Intel and AMD mini PCs when gaming. Note: This article has been updated and corrected as a result of reader feedback and additional testing. It was inspired by having built and tested a pseudo ‘Steamdeck’ running Manjaro on an AMD-based mini PC with 16GB of memory, which made me wonder what the performance would be like using Windows 11. Initial results were surprising because Windows appeared much slower. As I’d previously heard of performance improvements when using 64GB of memory I swapped out the currently installed 16GB memory and immediately saw improved results. As I’d never observed such a dramatic performance increase on Intel mini PCs just through increasing the memory I decided to explore further by testing gaming performance on similar Intel and AMD mini PCs when using […]

AMD Athlon 300U powered AM02 Mini PC goes for $240 and up

It’s not that easy to find a relatively low-cost AMD mini PC, and there are more choices on Intel’s side.  Most models around $250-$300 are barebone without memory or storage, but AM02 mini PC may be an interesting option as the AMD Athlon 300U powered computer sells for about $240 plus shipping with 8GB RAM and a 128GB SSD, which looks to be an even better option than the Maxtang MTN-FP50 mini PC we reported on last June. All AM02 models ship with Windows 10 by default, but you may be able to ask the seller to install Linux instead (TBC), and support up to 16GB RAM and 1TB SSD. Note that the seller apparently made a mistake with the 16GB/256GB model, as it is sold for just $232.89, instead of $332.89. It might still be worth a try 🙂 AM02 specifications: SoC – AMD Athlon 300U dual-core/quad-thread processor @ […]

Ryzen Embedded V1807B AI Edge PC supports dual-slot graphics cards

Many AI edge computers come with dedicated AI accelerators from Intel, Google, Gyrfalcon, and others. But as we’ve seen with Cincoze GM-1000 embedded mini PC, some include support for more traditional GPUs, in this case, an NVIDIA Quadro Embedded P2000 MXM module. Ryzen Embedded V1807B powered Vecow MIG-1000 AI edge PC is another such solution with up to 64GB DDR4, four DisplayPort outputs, and a PCIe x16 slot for dual-slot graphics cards from Nvidia or AMD for AI processing performance and/or extra video outputs. Vecow MIG-1000 specifications: SoC – AMD Ryzen Embedded V1807B quad-core processor with Radeon Vega 11 graphics; 35-54W TDP System Memory – 2x DDR4 3200MHz SO-DIMM, up to 64GB Storage – 1x SATA-III port, 1x M.2 Key M socket (2280, PCIe x4) for NVMe SSDs Video Output – 4x DisplayPort up to 4096 x 2160 @ 60Hz Audio Realtek ALC662, 5.1 Channel HD Audio codec 1x Mic-in, […]

Year 2020 in review – Top ten posts and stats

It’s this time of the year when we look back at what happened, and what may be next. 2020 did not pan out as planned in more ways than one, but there were still some interesting developments. Based on 2019 announcements, 2020 was promising to be an exciting year for Amlogic and Rockchip with the expected launch of RK3588 and S908X high-end processors for 8K capable devices,  but we’ll have to wait for 2021 for this to happen. Instead, the most interesting processor of the year from the Allwinner, Amlogic, and Rockchip offerings was probably Amlogic S905X4 processing adding AV1 hardware decoding. As pointed out in our “RISC-V 2020 highlights” post, it was a fairly eventful year for RISC-V architecture, although there’s still a long road ahead, especially for application processors. We had seen some general-purpose and Bluetooth RISC-V MCUs in 2019, but 2020 saw the launch of the first […]

AMD Launches Chromebook-Optimized Ryzen and Athlon 3000 C-Series Mobile Processors

After unveiling Athlon 3000-series of 15W mobile processors earlier this year, AMD has now announced Chromebook-optimized mobile processors with AMD Ryzen and Athlon 3000 C-Series family. Designed in collaboration with Google, the new AMD mobile “Zen” processors deliver up to 178% faster web browsing and 212% better performance for multitasking and content creation compare to the previous generation AMD A6-9220C powered Chromebooks. There are currently five 15W Ryzen/Athlon 3000 C-Series processors for Chromebooks. All processors are manufactured with a 12nm CMOS processor and look to be based on existing AMD U-series processors namely AMD Ryzen 7 3700U, 5 3500U, Ryzen 3 3250U, Athlon Gold 3150U, and Athlon Silver 3050U. All basic parameters are the same on AMD Chromebook-optimized processors, and it’s unclear to me what the differences are exactly. AMD also reported other performance metrics around with AMD Ryzen 7 3700C Mobile Processor offering up to 251% better graphics performance, […]
