9.0
If it's maximum multi-threaded throughput for minimum cash, take it from us, the Athlon II X4 620 is definitely your bag.

What People Are Saying Give it to me straight

Socket Type

When an Athlon II X4 processor is combined with a sub-$100 motherboard featuring the AMD 785G chipset, you can clearly see that AMD has a great platform at a very solid price point for Windows 7 when it launches next month.
by Legit Reviews (Sep, 2009)
AMD has plenty of processors on the market as you can tell from the chart above, but when it comes to quad-core offerings the AMD Athlon II X4 620 is $44 less expensive than the previous entry level quad-core, which would have been the Phenom II X4 810.
by Legit Reviews (Sep, 2009)
The AMD Athlon II X4 620 and Athlon II X4 630 processors offer nothing new or inspiring on the performance front, but they have a price point that will make you smile.

Socket

Here is a CPU-Z v1.52.2 screen shot of the AMD Athlon II X4 630 processor with all default settings to see what we are going to be overclocking.
by Legit Reviews (Sep, 2009)
Both of these processors feature a 200MHz bus with a 2000MHz HT link and memory support for both DDR2 (up to 1,066 MT/s) and DDR3 (up to 1,333).
by Legit Reviews (Sep, 2009)
By cranking the voltage up to 1.55V and lowering the HT link down to 8x from 10x we were able to get the system to 3.85GHz thanks to a bus speed of 275MHz.

Performance

Legit Bottom Line: The AMD Athlon II X4 series of processors offers an excellent value for consumers that are looking to build entry level and mainstream system builds.
by Legit Reviews (Sep, 2009)
Crank up the clocks at it will even do a passable job as a gaming chip.
by Tech Radar (Sep, 2010)
Benchmark Results: For not having any L3 cache the AMD Athlon II X4 620 and Athlon II X4 630 processors do fairly well in 3DMark06.
by Legit Reviews (Sep, 2009)

Applications

But strictly speaking, the limited cache memory and modest stock clockspeed do hammer the 620's performance in games.
by Tech Radar (Sep, 2010)
Actually, you can see how the test system is GPU limited by the GeForce GTX 295 in this game as the performance hits a wall even though the clock frequency of the CPU was increased.
by Legit Reviews (Sep, 2009)
In fact, any software that demands a lot of pulling power from a single core is going to chug a little on this cut-price quad.
by Tech Radar (Sep, 2010)

Overclocking

Considering that it has solid performance numbers, reaches an overclock of nearly 1GHz and costs just $99, there really isn't too much bad to say about it.
by Legit Reviews (Sep, 2009)
Getting more than 1Ghz overclocks out of $99 and $122 processor is always fun because they really turn into 'budget beaters' and are able to outperform processors that usually cost significantly more than they do.
by Legit Reviews (Sep, 2009)
It was also able to reach over 3.8GHz, which is a fairly massive overclock for just air cooling.
