After a three quarter delay, AMD launched L3 cacheless Deneb quad-cores, something that company codenamed Propus.

We don’t know the right reason why the CPU got delayed for such a long time and we hope that this is not merely a Deneb core with disabled cache. If this is a native cacheless CPU you should not be able to enable L3 cache and turn a Propus (Athlon II X4) into a Deneb (Phenom II X4).

The official brand is Athlon II X4 640 and this baby will run at 3.0GHz and will only have 4x512KB L2 cache, and no L3. There is still a chance that some of these CPUs will actually be Denebs and that some hack might let you enable the hidden L3 cache. We will look into this one.

TDP is the usual 95W which is the same as what Deneb has. In comparison with usual Deneb we believe that performance difference won’t be big either.
