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.

The NVIDIA SHIELD Android TV Review: A Premium 4K Set Top Box

The battle for the living room (i.e, controlling the television experience) is heating up with forays from multiple vendors. As the cord-cutting trend gains momentum, the time seems to be right for disruption. Roku has been around for a long time and they continue to taste success with inexpensive and small over-the-top set-top boxes (OTT STBs). At the other end of the spectrum is the Apple TV, which, despite just being a 'hobby', has managed to move millions of units. Google had tried to make inroads into this market a few years back with the Google TV / Logitech Revue, but, it unfortunately didn't pan out as expected. Chromecast turned out to be more popular in their second attempt, but it was a limited play. In late 2014, Google launched Android TV along with the Nexus Player. Read more

Red Hat CEO: Here's how to create an 'Open Organization'

In a brand-new book, Red Hat CEO Jim Whitehurst explains what he's learned from leading the largest open source company and how the lessons can be applied Read more Also:

  • The open source CEO strikes again
    In The Open Organization, Red Hat CEO Jim Whitehurst presents a compelling, modern alternative to the traditional, top-down hierarchy of business organization. I had the pleasure of interviewing Whitehurst for TechCrunch.com in early 2012, and the seeds of many of the ideas in the book were clearly present even then. Reading The Open Organization felt, in some ways, like the conclusion to that interview.
  • Why I Wrote "The Open Organization"
    In my line of work, I get a lot of questions. Most of these are along the lines of "What's it like to be CEO of an open source company" or “Where do you see technology moving over the next year?”

Fedora's "Fedup" To Be Replaced In Fedora 23

Fedup right now is the command for handling in-place Fedora upgrades from release-to-release and it's been around since Fedora 17. However, with the Fedora 23 release due out in late 2015, that utility will likely be replaced with a new version to handle upgrading to new releases. Read more
