Conclusion: We really find it difficult to recommend the Athlon II X4 to anyone because it has very few redeeming features. Its very high power use for the minimal transistor count is strange and confusing: why is there the need to throw at hefty 1.4V through the core to run the chip at 2.6GHz?
Conclusion: This is a pretty decent CPU, for 90$ you get alot of performance especially if you overclock the CPU a little bit. It performs better than 905e in stock performance and cost almost half the price.
Summary: Even if AMD is not leading the market in terms of pure brute performance, it still finds categories where it can brand the product with "world's first". This time, it's the world's first and still only quad-core processor with a price under $100.
Pros: Great pricing, Good performance, Low power consumption and heat, Good overclocking and great underclocking potential, Same list of technology support as Phenoms, Socket AM2/DDR2 compatibility
Cons: Lower gaming performance, Not the best choice for die hard overclockers, High stock voltage
Summary: Our timed benchmarks showed evidence that the Athlon II X4 630 and 620 perform slightly slower than Intel's cheapest quad core, the Q8200, in mundane everyday tasks like anti-virus scanning and file archiving.
AMD Athlon II X4 620 and 630: introducing the budget quad-core CPUs
16 September 2009
Conclusion: AMD's release of the Athlon II X4 620 and 630 brings quad-core processing to budgets that previously would have been swallowed by decent dual-core chips. Starting off at around £75 for the 2.6GHz-clocked '620, performance is partially castrated by the removal of 6MB of L3 cache when compared with...
Excerpt: AMD has recently expanded the Athlon II product line to include quad core processors, under the codename Propus. We are going to be taking a look at the two new Quad-Core processors, the Athlon II X4 620 and Athlon II X4 630 which operate at 2.6GHz and 2.8GHz respectively.
