AMD's quad core with no L3 cache.
As can clearly be seen, the die shot confirms that the CPU will have only 512KB of L2 cache per core. Below, the "Regor" AMD Athlon II X2 core with 1MB of L2 cache for comparison:
"Propus" is expected to debut in the third quarter, although it has already been delayed a few times. Processors based on this core will be branded as AMD Athlon II X4 600 series and as AMD Athlon II X3 400 series, which will be a cut down "Propus" core codenamed "Rana".
Die size for these processors is estimated at 168mm2, allowing AMD to become competitive with Intel's 45nm Core 2 Duo and Quad, which have a die size of 107mm2 and twice that for the quad core. Although the Athlon II X4 is expected to be cheaper but slower than the Core 2 Quad, it may prove a big problem for Intel's Core 2 Duo E8000 series.
