AMD Athlon X4 880K Processor Review & Overclocking to 4.5 GHz

File Encryption and Compression Testing

File encryption and compression are two heavy CPU usage tasks.  CipherShed is based on TrueCrypt, and is an open source encryption program.  Included with CipherShed is the same benchmark that made TrueCrypt an important tool in analyzing encryption performance. While 7-Zip is a very common tool that users might find themselves using to compress data for email, or saving storage space

Legit Reviews Benchmark Results:  As we stated, file encryption and compression uses advanced algorithms to manipulate the data, which uses the CPU processing power to it’s fullest.  We expect a big difference between the Intel i5 and the AMD 880K.  The difference between the two low cost options though, was a bit surprising.  For encryption, the difference was between 13% and 33% depending on the type of encryption you wanted to use.  File compression, the 880K took an even stronger lead, with between 25% and 40% better performance.

    I run an 880k with stock fan (Non Overclocked) and my idle temp I got range between 50 to 60 celcius. and when I load game such as Ark Survival Evolved, the temp would rise to 75 – 80 celcius and constantly stays there. After a while, the game would quit back to desktop. Anyone know why I am getting such high reading for my temperature?

      Airflow. Almost certainly airflow. If your CPU overheats mid game and over 20mins has passed, this means your case is gradually warming up to the point that the air going through the coolers themselves is warm and thus not great at taking away heat. You need to look at your case, wiring and case fans etc etc and get some cool air moving in.

      i have an 880k i ran it at 4.5 ghz with no problems, but i think the temp readings are inaccurate because i use biostar a88mq mobo which has a temp monitor, i played gta v for about 2 hours then i forced restart the sys, go into the bios and it was reading around 47 celcius. i put my hand aroung the exhuast fan and it warm NOT HOT.

    what was your voltage

    I have an 880k clocked at 4,5 and i am never getting over 40 fps and average is below 30fps in GTA v at any resuloution. This is paired with a MSI 960 4gb which would not bottle neck this CPU at all! Is something wrong? I have 8 gig dddr3 ram, stock cooler (running very cool) and a 450w PSU. And yes my GPU is not disabled!

      Something is very wrong, but it’s not necessarily the CPU. Maybe drivers. I can get 30fps on a 560ti with this chip, and that’s definitely a GPU bottleneck. Look at a bigger PSU as you may be limited there. Remember that 450w is how much it takes from the wall, not how much it gives to your parts so when you buy a $20 450W unit, it can be up to 50% efficient, giving only 200W to your computer and giving you what looks like major gremlins.

    question; why not include an i3 in the comparison for this review?

    • Steven Kean

      I didn’t have one on hand to test 🙁 Wish I could get all the processors needed to cover all the bases. I am looking forward to Intel’s Kaby Lake i3 Overclocking processor though…hope to have one.

        Guess you need to do a Ryzen 3 one instead with all the news.
