AMD Athlon II X4 620 Quad Core Processor Review

» Discuss this article (76)


I have to say, I am very impressed with the new Athlon II X4 series processor. This baby performed very well despite having a low L2 cache, no L3 cache and a low clock speed of 2.6GHz. While it was no match for the Intel i7 series, it did come close when put up against the Intel i5 series in the gaming benchmarks and some of the scientific ones as well. When put up against the Phenom II X4 it came even closer, especially in benchmarks where the system as a whole was benchmarked and not just the CPU by itself. When it comes to overclocking, while it will not break any speed records, it did very well considering the multiplier is locked at 13x. I was able to turn up the reference clock to a nice 241MHz at 1.5 volts and the temperature stayed a cool maximum of 38C degrees under water, which is very cool considering the voltage pumping into it. When not overclocked, the processor never broke 25C degrees with the ambient temperature at a constant 22C degrees. This processor was a pleasure to use and shows great promise for those wanting to run a good and decently powerful system without spending a lot of money. At launch, the Athlon II X4 620 is going to be selling for only $99, which is unheard of for a quad core processor, especially one that performs this well for the price. When paired with the 790X motherboard used for this review, you have a nice setup for a workstation or a gaming computer for under $230. You have to admit, that is a very good start for that nice gaming rig you have been wanting to build but were limited on the funds. If you are needing a good quad core processor for your next build I would without a doubt encourage you to look into the new Athlon II X4 series because it will be money well spent.



  • Under $100 for a Quad Core processor
  • Performs very well with price per performance ratio
  • DDR2 and DDR3 memory compatible
  • HyperTransport 3.0



  • Low L2 cache and no L3 cache
