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.

Full Review.

Leftovers: Ubuntu

  • Ubuntu Phone, Sep 2016 - Vorsprung durch Touch
    The Ubuntu Phone is getting better, and with every new iteration of the OTA, my little BQ Aquaris E4.5 is gaining more speed and functionality. Like in the air force, with an avionics upgrade, which transforms ancient wings into a powerful and modern bird of prey. Only the pace of advancement is lagging behind the market. See what Android and iOS can do, even Windows Phone, and you realize how late and insufficiently meaningful the Ubuntu Phone really is. This has to change, massively. This latest round does bring some fine goods to the table - more speed and stability, better icons, more overall visual polish, incremental improvements in the applications and the scopes. But that's not enough to win the heart of the average user. A more radical, app-centric effort is required. More focus on delivering the mobile experience, be it as it may. Ubuntu cannot revolutionalize that which is already considered the past. It can only join the club and enjoy the benefits of a well-established reality. And that is a kickass app stack that makes the touch device worth using in the first place. Still, it's not all gloomy. E4.5 is a better product now than it was a year ago, fact. Ubuntu Phone is a better operating system than it was even this spring, fact. So maybe one day we will see Ubuntu become an important if not dominant player in the phone and tablet space. It sure is heading in the right direction, my only fear is the availability of resources to pull off this massive rehaul that is needed to make it stand up to the old and proven giants. And that's it really. If you're keen on Linux (not Android) making it in the mobile world, do not forget to check my Ubuntu tablet review! Especially the convergence piece. On that merry note, you do remember that I'm running a wicked contest this year, too? He/she who reads my books might get a chance to win an M10 tablet. Indeed. Off you go, dear readers. Whereas I will now run the same set of tests we did here on the Aquaris tablet, and see how it likes the OTA-12 upgrade. The end.

  • Another Setback for 3D Printed Gun Advocate Cody Wilson as Court of Appeals Rules That National Security Concerns Outweigh Free Speech
    It’s been a long, drawn-out battle, beginning in 2013 when Cody Wilson, founder of Defense Distributed, published the open source files for his 3D printed handgun, the Liberator, online. The State Department ordered that he take the files down, and Wilson complied, but not before thousands had downloaded them and spread them elsewhere on the Internet. In 2015, with the help of gun rights organization The Second Amendment Foundation, Wilson filed a federal lawsuit claiming that the State Department had violated not only his Second Amendment but his First Amendment rights. By suppressing his right to share information online, Wilson argued, the State Department was violating his right to free speech.

  • Oracle tries playing nice with Java EE rebels
    With Oracle now trying to get back on track with advancing enterprise Java, the company is seeking rapprochement with factions that had sought to advance the platform on their own. The two groups involved are mostly amenable to patching up the relationship. Oracle's Anil Gaur, group vice president of engineering, said this week he had already been in touch with some of the concerned parties. The two factions include Java EE Guardians, led by former Oracle Java EE evangelist Reza Rahman, and Microprofile.io, which has included participation from Red Hat and IBM.
