AMD have just quietly released a couple of new processor models in their Athlon 64 X2 series for socket AM2, these topping the lineup as the 5400+ and 5600+ with the same clock speed of 2.8Ghz. They differ due to the amount of cache onboard, the 5400+ coming with 2x512KB of L2 and the 5600+ with 2x1MB (making it equally spec'd to the FX-62 only without the unlocked multiplier).

Also mentioned at the Inquirer is a couple of even higher-end models due for launch in the near future, these being the 5800+ and 6000+.

AMD TODAY SILENTLY added two new processors to its price list and officially rebranded former ATI chipsets, as was leaked over a month ago. This is in preparation for its Analyst Day, which is going to be held in just a few days.

The new CPUs come in 5400+ and 5600+ variants, but the clock speed for both is the same: 2.8GHz. The difference is the amount of L2 cache per core. While the 5400+ comes with X2-typical 512KB per core (total: 1MB), the 5600+ comes with 1MB of L2 cache per core (total: 2MB) giving it equal specs to top-of-the-line AM2 CPU, the Athlon 64 FX-62 and the newly introduced FX-72 (the one using Socket 1207FX).
