cpu-world.com comparison of 2 CPUs
I mentioned pcpartpicker.com in a previous post as a good site for assembling a computer, but what do you do when you want to compare the features of 2 CPUs? I’ve found cpu-world.com to be a great resource for comparing the features of CPUs, it’s how I decided on the AMD A8-5600K CPU for my next budget build. I compared similarly priced modern Intel dual core systems to the A8-5600K (the A8-5600K is a quad core) before settling on it.
The comparison doesn’t show particular applications (for example showing how each perform encoding a movie), but talks about trade-offs like “uses more power,” or “is 25% faster on multi-threaded applications.”
Cpu-world.com sometimes also displays information such as whether the CPU was originally a boxed CPU or an OEM (Original Equipment Manufacturer) CPU made for a line of machines.
Gsmartcontrol overall information
Gsmartcontrol is a fantastic Linux program for checking grabbing smart information from hard drives. One of the great things about gsmartcontrol is that the hard drive doesn’t need to even be partitioned or formatted. Gsmartcontrol needs to be run as root, but don’t worry if you’re running Xubuntu or one of the other Ubuntu derivatives, it’ll run straight from the menu. If you get a Unknown device message you know that you’re not running as root.
Gsmartcontrol has 7 tabs: Identity, Attributes, Capabilities, Error Log, Self-test Logs and Perform Tests. As soon as gsmartcontrol loads you might see red on the Error Log and Attributes tabs – don’t panic – yet! Often we see drives with errors where the drive has come across a bad sector at some point and marked the bad sector. Drives can work with bad sectors (notice the Overall Health Self-Assessment Test has PASSED). Typically I click the Perform Tests tab to run a short test on the hard drive. If the drive passes but the Error Log shows a lot of errors I’ll consider replacing the drive. You’ll also want to check out the Self-Test Logs which shows the amount of hours the drive has on it. Anywhere near 50,000 hours and you should seriously consider replacing the drive.
Gsmartcontrol initial screen
I’ve tested about a dozen 250GB SATA hard drives and found that drives with more than 26000 hours on them tend to have a number of errors. Out of a dozen, if I remember correctly, about 5 were in bad enough shape that I wouldn’t even consider using them. Good rule of thumb, if it fails the short test back it up and get another drive.
Gsmartcontrol is not installed by default in Xubuntu/Ubuntu so you’ll have to install it.
sudo apt-get install gsmartcontrol
Another use for gsmartcontrol is grabbing the model number/identifying hard drives, or grabbing the hard drive serial number (for insurance purposes).
