AMD Athlon II X3 435 & Athlon II X2 240e Processor Review

» Discuss this article (5)


To test the new AMD Athlon II X3 435 and Athlon II X2 240e processors, I will be running them through a series of scientific and video based benchmarks that are designed to stress them and push them to the limits.  These benchmarks will demonstrate how well they stand up and perform. To give us a clear sense of where they sit among other processors, I will be putting them up against an Athlon II X4 Quad Core and the new Intel Core i5 series processors.  This will give you an idea of where they sit in relation to other hardware paths you may be considering. Will reducing the number of cores sacrifice a large amount of performance? We will have to see for ourselves.


Testing Setup AMD AM3 CPU's:


Testing Setup: Intel Core i5/i7 Socket 1156


Comparison CPUs:



Overclocked settings:

  • Processor: AMD Athlon II X3 435 @ 3.65GHz (252x14.5) 1.50v | Processor: AMD Athlon II X2 240e @ 3.150GHz (225x14) 1.425v
  • System Memory: Corsair XMS3 DHX @ 1680MHz (8-8-8-24) | System Memory: Corsair XMS3 DHX @ 1500MHz (7-7-7-20)

To overclock the new Triple Core and Dual Core, the process is a bit trickier than overclocking the Phenom II's that have unlocked multipliers.  To overclock the AMD Athlon II X3 435 and the AMD Athlon II X2 240e, you need to adjust the reference clock of the CPU, which, in turn, affects not only the processor speed, but the memory and HyperTransport speeds as well. To accomplish this, you need to have a balance between all parts to remain stable and achieve the best possible performance. I started each one by dropping the multiplier and strap for the HyperTransport BUS and the memory. I then pushed up the reference clock 10MHz at a time while increasing the CPU voltage to keep the system stable. As I reached the wall and could not go any more, I would back off 1MHz at a time until I was able to keep the system not only stable, but able to pass CPU intensive benchmarks as well. As I reached the balance, I was able to benchmark the system without any issues. The final overclock for the Athlon II X3 435 was 3.65GHz (252 x 14.5) at 1.5v and a memory speed of 1680MHz at 8-8-8-24 timings. For the Athlon II X2 240e, the final settings were 3.150GHz (225 x 14) at 1.425v with the memory at 1500MHz with timings 7-7-7-20.
