AMD Phenom X4 9850 

Released July, 2008
  • 2.5 GHz
  • Quad core
  • Unlocked
4.8 Out of 10

The original Phenom 9900 that we looked at back in November could do 3.06GHz at 1.45V, so reaching 2.97GHz is close to the best we have ever seen with Phenom.

Additionally, it'll overclock on air (with a spot of volt-tweaking) to 3GHz, but realistically bank on a bump of 200-300MHz.

Reviews Word on the street for the AMD Phenom X4 9850


6.0
Its low cost offsets performance issues, but performance issues still plague the latest Phenom.

8.0
If, however, you're building a new system, AMD simply has nothing to compete with the higher-end Core 2s.

What People Are Saying Give it to me straight

Socket Type

When it comes to benchmarks, the move from 2.50GHz to 2.97GHz increased performance by 25%, which is great considering the overclock was only 18.
by Legit Reviews (Mar, 2008)
The four new AMD Phenom X4 processors that AMD is announcing today are the 9550 (2.2GHz), 9650 (2.3GHz), 9750 (2.4GHz) and 9850 Black Edition (2.5GHz).
by Legit Reviews (Mar, 2008)
The AMD Phenom X4 9850 that we will be benchmarking today is a 2.5GHz processor manufactured using AMD's 65nm Silicon on Insulator process technology.
by Legit Reviews (Mar, 2008)

Socket

For example, the 2.2GHz Phenom 9550 processor will replace the Phenom 9500 (B2) processor.
by Legit Reviews (Mar, 2008)
With the bus speed set to 200MHz we were able to take the divider up to 14, which means 2.80GHz was reached.
by Legit Reviews (Mar, 2008)
Higher performance AMD Phenom processors will follow the introduction of the AMD Phenom 9700 and 9900 models, with a 3.0 GHz model in Q2 2008.
by Legit Reviews (Mar, 2008)

Performance

The launch of these two higher performance processors models will coincide with the introduction of related, significant performance enhancements in the platform; namely CrossFireX and our new enthusiast graphics product.
by Legit Reviews (Mar, 2008)
Not only is performance the same clock-for-clock, but so is pricing as it should be.
by Legit Reviews (Mar, 2008)
The Phenom 9850 Black Edition does much better on this benchmark now that the TLB erratum has been fixed.
by Legit Reviews (Mar, 2008)

Multicore

AMD has now stopped production on the older core steppings as a result of this change.
by Legit Reviews (Mar, 2008)
The lack of a core multiplier is a big plus for system tweakers.
by PCMag (Jun, 2008)
Legit Reviews asked AMD about this since it seems a bit strange that they are using the old stepping on the initial batch of triple-cores.
by Legit Reviews (Mar, 2008)

Overclocking

Since the bus speed can't be raised that high on Phenom processors the best way to overclock is by increasing the multipler and the Black Edition was designed just for that.
by Legit Reviews (Mar, 2008)
The chip has a Max TDP of 125W and it is a 'Black Edition', which means its multiplier is unlocked for better overclocking.
by Legit Reviews (Mar, 2008)
Since we were not able to top our previous best it can be fair to assume that the B3 overclocking should be very close to that of previous versions.
