AMD Introduces New Ryzen Mini PCs To Challenge Intel

December 24, 2019 by Tom Nardi 55 Comments

For the majority of hacker and maker projects, the miniature computer of choice these last few years has been the Raspberry Pi. While the availability issues that seem to plague each new iteration of these extremely popular Single Board Computers (SBCs) can be annoying, they’ve otherwise proven to be an easy and economical way to perform relatively lightweight computational tasks. Depending on who you ask, the Pi 4 is even powerful enough for day-to-day desktop computing. Not bad for a device that consistently comes in under a $50 USD price point.

But we all know there are things that the Pi isn’t particularly well suited to. If your project needs a lot of computing power, or you’ve got some software that needs to run on an x86 processor, then you’re going to want to look elsewhere. One of the best options for such Raspberry Pi graduates has been the Intel Next Unit of Computing (NUC).

NUCs have the advantage of being “real” computers, with upgradable components and desktop-class processors. Naturally this means they’re a bit larger than the Raspberry Pi, but not so much as to be impractical. If you’re working on a large rover for example, the size and weight difference between the two will be negligible. The same could be said for small form-factor cluster projects; ten NUCs won’t take a whole lot more space than the same number of Pis.

Unfortunately, where the Intel NUCs have absolutely nothing on the Raspberry Pi is price: these miniature computers start around $250, and depending on options, can sail past the $1,000 mark. Part of this sharp increase in price is naturally the vastly improved hardware, but we also can’t ignore that the lack of any strong competition in this segment hasn’t given Intel much incentive to cut costs, either. When you’re the only game in town, you can charge what you want.

But that’s about to change. In a recent press release, AMD announced an “open ecosystem” that would enable manufacturers to build small form-factor computers using an embedded version of the company’s Ryzen processor. According to Rajneesh Gaur, General Manager of AMD’s Embedded Solutions division, the company felt the time was right to make a bigger push outside of their traditional server and desktop markets:

The demand for high performance computing isn’t limited to servers or desktop PCs. Embedded customers want access to small form factor PCs that can support open software standards, demanding workloads at the edge, and even display 4K content, all with embedded processors that have a planned availability of 10 years.

Modder Puts Computer Inside A Power Supply

November 24, 2017 by Anool Mahidharia 15 Comments

When building a custom computer rig, most people put the SMPS power supply inside the computer case. [James] a.k.a [Aibohphobia] a.k.a [fearofpalindromes] turned it inside out, and built the STX160.0 – a full-fledged gaming computer stuffed inside a ATX power supply enclosure. While Small Form Factor (SFF) computers are nothing new, his build packs a powerful punch in a small enclosure and is a great example of computer modding, hacker ingenuity and engineering. The finished computer uses a Mini-ITX form factor motherboard with Intel i5 6500T quad-core 2.2GHz processor, EVGA GTX 1060 SC graphics card, 16GB DDR4 RAM, 250GB SSD, WiFi card and two USB ports — all powered from a 160 W AC-DC converter. Its external dimensions are the same as an ATX-EPS power supply at 150 L x 86 H x 230 D mm. The STX160.0 is mains utility powered and not from an external brick, which [James] feels would have been cheating.

For those who would like a quick, TL;DR pictorial review, head over to his photo album on Imgur first, to feast on pictures of the completed computer and its innards. But the Devil is in the details, so check out the forum thread for a ton of interesting build information, component sources, tricks and trivia. For example, to connect the graphics card to the motherboard, he used a “M.2 to powered PCIe x4 adapter” coupled with a flexible cable extender from a quaint company called Adex Electronics who still prefer to do business the old-fashioned way and whose website might remind you of the days when Netscape Navigator was the dominant browser.

As a benchmark, [James] posts that “with the cover panel on, at full load (Prime95 Blend @ 2 threads and FurMark 1080p 4x AA) the CPU is around 65°C with the CPU fan going at 1700RPM, and the GPU is at 64°C at 48% fan speed.” Fairly impressive for what could be passed off at first glance as a power supply.

The two really interesting take away’s for us in this project are his meticulous research to find specific parts that met his requirements from among the vast number of available choices. The second is his extremely detailed notes on designing the custom enclosure for this project and make it DFM (design for manufacturing) friendly so it could be mass-produced – just take a look at his “Table of Contents” for a taste of the amount of ground he is covering. If you are interested in custom builds and computer modding, there is a huge amount of useful information embedded in there for you.

Thanks to [Arsenio Dev‏] who posted a link to this hilarious thread on Reddit discussing the STX160.0. Check out a full teardown and review of the STX160.0 by [Not for Concentrate] in the video after the break.
