Anyone else who’s been around long enough to remember buying an AMD Thunderbird, Palomino, Barton etc. feeling the urge to build a new AMD system to replace their existing system?

My primary desktop is still being powered by a FX-8350 I bought November 2012 - while for everything I do (mainly Visual Studio and SQL Server) coupled with my Samsung SSDs, Radeons etc. it's ok, it just feels extremely weird to not have an upgrade path (ignoring the FX-9000 series) after years of doing a new year build every year or every other year (back in Athlon XP days it was every couple months). In the mean time I've built 2 Kabini systems this year, one as a ClearOS firewall and another as a HTPC and while those have worked out extremely well, there is a void in that my primary machine is relatively unchanged for almost 2 years.

I know there is always the Intel route - an i7 would be a definite upgrade, I know it is silly, I just can't bring myself to doing it. When I switched to AMD December 2000 with a 1 GHz Athlon it seemed like more of an experiment. AMD wasn’t new to making CPUs, but it was new in beating Intel in both price and performance. I had an aging Celeron 300A and tons of new First Person Shooters to play, the Athlon made sense then and if I had to do it again, I most definitely would. The summer before, in 1999 after having worked on the Army base doing Sys Admin work I had over a $1000 to burn – I almost pulled the trigger on building the parts for a Dual Pentium 3 600mz (buying only 1 CPU that summer since they were several hundred dollars). Thankfully, my dad convinced me to instead buy a 19” iiyama CRT (1600x1200) to replace my 15” CTX CRT (1024x768) – much more bang for the buck. Thus the following Christmas in 2000 I received some money and fortunately had enough to buy an Abit KT7-A, 256mb of PC133 ram and a 1ghz AMD Athlon (Socket A) – looking back had I still had my summer job in Germany, I might have built 2 of them since they were so cheap in comparison to the Pentium 3 idea the summer before.

I hope the new AM3+ platform replacement (latest rumor I read was next year) can really bring AMD back to the top. The FM2+ platform is nice, but the lack of 8 core variants without an iGPU is I feel definitely hurting AMD especially those sitting on the AM3+ platform like myself who would love to stay with AMD, but have nothing to upgrade to.

Saturday morning after resolving my Realtek RTL8111-GR Issues on my new ClearOS box, I ran into yet another error:

nommu_map_single

Knowing the AM1 Platform that my AMD Athlon 5350 APU/ASUS AM1I-A motherboard run on more than likely does not support IOMMU like my desktop's 990FX does I figured it was a detection issue with the Linux kernel that ClearOS 6.5 utlizes.

Doing some research into the issue there are a couple adjustments to your GRUB configuration that may or may not resolve the issue. In my case adjusting my GRUB arguments upon boot to include iommu=soft resolved the issue. I'm hoping down the road with newer Linux kernels the detection (if that even is the issue) gets better, but for those running an AMD "Kabini" APU and ran into this issue you'll at least be able to boot into your Linux distribution without any issues.

I received my AUS AM1I-A and AMD 5350 (Kabini) APU along with the rest of the components for my new firewall system last night (a detailed build write up will come tomorrow night). For those curious about the raw CPU Integer and Floating Point performance here are the results from my newly updated Linux port of jcBENCH.

[bash] jcBENCH 0.8.755.0504(x86/Linux Edition) (C) 2012-2014 Jarred Capellman CPU Information --------------------- Manufacturer: AuthenticAMD Model: AMD Athlon(tm) 5350 APU with Radeon(tm) R3 Count: 4x2046.077mhz Architecture: x86 --------------------- Running Benchmark.... Integer: 1.99601 seconds Floating Point: 8.44405 seconds [/bash] In comparison to my FX-8350, with a 4 threaded limit, the Kabini based APU is actually faster than my FX-8350 (3.02 and 11.67 seconds respectively). In single and dual threaded tests, I imagine the results are far different. More thorough results will come tomorrow.
