AMD Athlon 64 4800+ X2 - Dual Core CPU

Reviews

On the 25th of April AMD announced loads of dual core stuff. Besides the launch of the dual core 8xx series Opteron it also announced the 2xx dual core Opteron and the dual core Athlon 64 X2. Today we’re a step closer to the launch of Athlon 64 X2 but it’s not here quite yet - you’ll have to wait until June for that pleasure. If only there was a large international IT trade show that started at the end of May why, that would be the perfect venue to announce a new processor.

Until the official launch happens we won’t be able to get our hands on a fully fledged Athlon 64 X2 PC, so what we have here is a technical preview based on an AMD press kit of an Asus A8N SLI Deluxe motherboard, an Athlon 64 X2 4800+ and 1GB of Corsair 3200XL Pro memory.

There are four processors in the Athlon 64 X2 family which share a number of features with each other, and with existing models of Athlon 64. Athlon 64 X2 continues to use socket 939, the fabrication process is 90nm (.09 micron) using SOI (Silicon on Insulator), the 128-bit memory controller is compatible with PC1600, PC2100, PC2700 and PC3200 DDR, although you’d be barking mad to use anything but top notch memory, and there’s one bi-directional 1GHz Hyper Transport link. This gives an effective data bandwidth of 14.4GB/sec (8GB/sec x1 HyperTransport link + 6.4GB/sec memory bandwidth). X2 has 64KB of L1 instruction and 64KB of L1 data cache, just like Athlon 64.

The second core raises the transistor count to 233.2 million, but thanks to the 90nm fabrication process the die size is only 199 square millimetres. Compare that to the 130nm SOI Athlon 64 4000+ and Athlon 64 FX-55 which have cores that use 105.9 million transistors but which have an area of 193 square mm and you’ll see what an effective die shrink can bring to the party.

The Athlon 64 X2 4800+ has a nominal operating voltage of 1.35-1.40V and a TDP (Thermal Design Power) of 110W which compares very favourably to the FX-55 at 104W and the 4000+ at 89W.

Add in support for SSE3 and a revised memory controller to help compatibility with a broader range of memory modules and what you’ve effectively got is a pair of the new Venice cores tied together with the dual Opteron crossbar.

Living The Linux Laptop Lifestyle

Another great advantage of open source software: you can run it off of a flash drive before installing it. And I have to admit that I loved Linux Lite's out-of-the-box feel, so much so that I reconsidered installing my number two selection: LXLE, which is designed for underpowered older machines. According to a label on the bottom of my Toughbook, this pre-Linux laptop was decommissioned in 2005, making it well over ten years old. And so I replaced the RAM, installed Linux Lite, and after a short period, I was back to living a Linux laptop lifestyle while waiting for my charger. Read more

Mentor Embedded Linux gains cloud-based IoT platform

Mentor announced a “Mentor Embedded IoT Framework” platform that builds on top of Mentor Embedded Linux with cloud-based IoT cloud services ranging from device authentication and provisioning to monitoring and diagnostics. Mentor’s Mentor Embedded IoT Framework (MEIF) extends its Yocto Project based Mentor Embedded Linux (MEL) and Nucleus RTOS development platforms to provide cloud services for IoT device management. The platform mediates between these platforms and cloud service backends, including Amazon Web Services (AWS), Eclipse IoT, Microsoft Azure, and Siemens MindSphere. Read more

Bang & Olufsen’s RPi add-on brings digital life to old speakers

B&O and HiFiBerry have launched an open source, DIY “Beocreate 4” add-on for the Raspberry Pi that turns vintage speakers into digitally amplified, wireless-enabled smart speakers with the help of a 180-Watt 4-channel amplifier, a DSP, and a DAC. Bang & Olufsen has collaborated with HiFiBerry to create the open source, $189 Beocreate 4 channel amplifier kit. The 180 x 140 x 30mm DSP/DAC/amplifier board pairs with your BYO Raspberry Pi 3 with a goal of upcycling vintage passive speakers. Read more
