Passively cooled PCs are an interesting niche, often associated with the need for silence. Be it audio recording or home theater appliances, some situations are just not well suited to having a whirring fan.
Recently announced is the fit-PC4 is a fanless system, fourth in its lineage. This time the system is using AMD for its CPU and GPU. Two models are available, separated into "Pro" and "Value". Its specifications are broken down into the table below.
|fit-PC4 Pro||fit-PC4 Value|
|Processor||AMD GX-420CA (25W TDP, Kabini)||AMD A4-1250 APU (8W TDP, Temash)|
|- CPU||Quad-core (Jaguar-based) @ 2.0 GHz||Dual-core (Jaguar-based) @ 1.0 GHz|
|- GPU||Radeon HD 8400E||Radeon HD 8210|
|RAM||Up to 16GB (2 DIMM)|
|Storage||2.5" HDD/SSD + mSATA + microSD|
2x HDMI 1.4a (1920x1200 max) with CEC support
S/PDIF, line-out, mic-in (I assume 3.5mm)
2x Gigabit Ethernet
mini-PCIe slot for cellular modem
2x USB 3.0 and 6x USB 2.0
|Bluetooth||4.0||3.0 + HS|
|Dimensions||16cm x 19cm x 3.7cm||16cm x 16cm x 2.5cm|
Interestingly, the company considers these devices "ruggedized" as well as fanless. As such, they have a 5-year warranty. It seems to be quite the feature-packed device with two HDMI 1.4 outlets, two Gigabit Ethernet ports, and an available slot for a cellular modem. The Pro even has 802.11ac WiFi. I am not entirely sure the intended purpose of this device, but the company claims that the previous generation product was often purchased by video surveillance and digital signage customers. Interestingly, Windows 7 and Linux are the two choices for operating systems.
The fit-PC4 is available now in either a $299 (Value-Barebone) or $380 (Pro-Barebone) model.
AMD Gives a Glimpse of the Near Future
AMD has released an updated roadmap for these next two years, and the information contained within is quite revealing of where AMD is going and how they are shifting their lineup to be less dependent on a single manufacturer. The Financial Analyst Day has brought a few surprises of where AMD is headed, and how they will get there. Rory Read and Mark Papermaster have brought a new level of energy to the company that seemingly has been either absent or muted. Sometimes a new set of eyes on a problem, or in this case the attitudes and culture of a company, can bring about significant changes for the positive. From what we have seen so far from Rory and company is a new energy and direction for AMD. While AMD is still sticking to their roots, they are looking to further expand upon their expertise in some areas, all the while being flexible enough to license products from other companies that are far enough away from AMD's core competence that it pays to license rather than force engineers to re-invent the wheel.
The roadmaps cover graphics, desktop, mobile, and server products through 2013.
This first slide is a snapshot of the current and upcoming APU lineup. Southern Islands is the codename for the recently released HD 7000 series of desktop parts. This will cover products from the 7700 level on up to the top end 7990. Of great interest are the Brazos 2.0 and Hondo chips. AMD had cancelled the "Krishna" series of chips which would have been based on Bobcat cores up to 4 on 28 nm. Details are still pending, but it seems Brazos 2.0 will still be 40 nm parts but much more refined so they can be clocked higher and still pull less power. Hondo looks to be the basic Brazos core, but for Ultra Low Power (lower clocks, possibly disabled units, etc.) which would presumably scale to 5 watts and possibly lower.
