AMD Athlon X2 7000 series Kuma processors arrive

Posted on Monday, December 15 2008 @ 16:28:11 CET by Thomas De Maesschalck |
A duo of new "Kuma" based dual-core processors from AMD arrived today as the Athlon X2 7000 series, these chips are basically 65nm Phenom (K10) processors with two of the four cores disabled. This new series features the 2.7GHz Athlon X2 7750 Black Edition and the 2.5GHz Athlon X2 7550.
The Athlon X2 7750 BE should retail for about $79 and competes with Intel Pentium Dual Core processors. You can find some reviews at X-bit Labs, Hexus, Bit Tech and TweakTown.
Overall the Athlon X2 7750 BE isn't that impressive. While it's an improvement over 65nm K8 chips, the chip isn't much better than the similar-priced Intel Pentium Dual-Core E5200/E5300 processors and it uses a lot more power.
The performance per watt is pretty bad, according to the X-bit Labs review, the X2 7750 uses 36W more in idle and 78W more in load than the Pentium DC E5300. To make it worse, the overclocking potential is very limited too. Overall the 45nm Pentium Dual Core are much more interesting than the new Kuma processors from AMD, but an Intel platform will be a bit more expensive than an X2 7750 and a cheap 780G based motherboard.
However, so far it is enough for dual-core AMD processors to retain certain parity in terms of performance with the competitors from Intel – Pentium DC. And although Intel has recently moved them to new 45nm cores, Athlon X2 7750 CPU remains a worthy rival not only to Pentium DC E5200, but also to the newer Pentium DC E5300.
At the same time all other consumer qualities of the new Kuma processors cannot stand any criticism. Athlon X2 7000 series made from Phenom CPUs consume a lot of power and are barely promising from the overclocking standpoint. Therefore, we can only recommend the new CPU from AMD with a number of allowances and comments to take into account.
