AMD has been busily revising its line of quad-core Phenom processors. After a somewhat lackluster debut, the Phenoms have received some upgrades. First came the Black Edition series, which allowed for overclocking flexibility, courtesy of an unlocked multiplier. AMD has now followed the original BEs with a set of processors bearing 50-series monikers: the 9550, 9650, 9750, and 9850.
These new 50-series processors ostensibly fix the TLB (translation lookaside buffer) problem that infamously hampered performance in previous Phenom releases. (If you listen closely, you can hear a collective cheer coming from AMD fans everywhere.) This fix finally lets AMD pit its processors against Intel’s without the performance handicap of the TLB.
The current king of the Phenom hill is the X4 9850 Black Edition. The 9850 boasts a clock speed of 2.5GHz, and it gets a slight performance boost from the 2GHz memory controller. Because the memory controller has its own power/voltage control and clock, memory performance isn’t mitigated by a divisor based on the CPU’s clock.
When comparing the benchmark scores of the 9850 to the Phenom 9600 Black Edition, it’s worth noting that at launch, each processor cost nearly the same: The 9600 was $239, while the 9850 will retail for $235. The scores for the 9850 are moderately better, with the only notable differences in specifications between the two a slightly slower processor (2.3GHz) and a slightly slower HyperTransport Link (3.6GHz) in the 9600.
With a $235 price tag, the 9850 is a relatively inexpensive processor. Although the problems in previous Phenom offerings caused us to balk at upgrading from Athlon 64 X2 processors, the TLB fix brings some peace of mind. For enthusiast-class gamers, hometheater nuts, or users who are looking for a serious upgrade to a Socket AM2-based system without having to build a new rig, the Phenom X4 9850 is a very nice option. It’s also a fine choice for users who are looking for a CPU around which to build a low-cost quad-core system.
Price(pkr) 19000.
