Unlocked Athlon II X4 620 Benchmarks

Get them while they're still not "Propus" based.

The motherboard used for the unlocking process was a Biostar TA790GX A2+, coupled with 4 GB of DDR2 memory.

Benchmarks (stock / unlocked L3 cache):

• Super Pi 1M: 31.174s / 26.645s
  
• Cinebench single core: 2759 / 3002
• Cinebench multi core: 9265(3.36x) / 10948 (3.65x)
• 3D Mark Vantage CPU: 8619 / 9004
  

These are some of the most relevant scores. The first score that pops out from the crowd is the Cinebench multi core, which scales better when the L3 cache is unlocked. This was the most predictable fallacy from the new Athlon II X4 processors, which can't share date on the L3 cache and have to synchronize in the main memory. They also have a rather small 512KB of L2 cache, which also causes them to perform worse in single core tasks, as the L3 cache would also help to reduce latency by keeping more data closer to the core. The drop here is not so big but applications like games will miss the extra cache more than others.

The stock Athlon II X4 looks like a very good proposition, especially considering that it will outperform Intel's more expensive Core 2 E8400($170) in some situations. Cinebench is an example of that, where the E8400 scores 7200 points. It's also faster than AMD's Phenom II X3 720 which scores ~8800 points.
While the X3 720 is dropping to the same price point as the Athlon II X4 - $110 - the Core 2 Duo is priced much higher, as are Intel Quad core offerings which offer only slightly better performance. Gaming performance won't be so great as with the Core 2 Duo E8400 but games are slowly moving to the multi threaded world where quad cores will reign.

AMD has a very competitive processor and the 45W versions at 2.2GHz and 2.3GHz will be very interesting processors also.
