Official AMD Kaveri APU Details

AMD is ready to announce two Kaveri Accelerated Processing Units, the A10-7700K and A10-7850K chips. AMD A10-7000 series processors have 4 "Steamroller" CPU cores, 4 MB L2 cache and 95 Watt Thermal Design Power. The A10-7700K has the maximum Turbo Core frequency of 3.8 GHz, and from earlier reports we also know that it integrates R7 series GPU with 384 Radeon cores. The pre-order price of this part is $167. The flagship A10-7850K has 200 MHz higher maximum Turbo Core speed, and has the number of Radeon cores increased to 512. Being faster, it is also more expensive. The chip is priced at $173, which suggests that its official price could be higher than the current price of the A10-6800K ($142).

According to the AMD presentation, the Kaveri can have up to 12 compute cores, which includes both the CPU cores and the GCN modules (graphics core next).

Both the A10-7700K and the A10-7850K have four GCN based Radeon modules, that means the A10-7850K and A10-7700K are quad-core CPUs with eight Radeon cores on top of it (512 stream processors at 654 MHz base and 720 MHz boost).

New dual-core A4-6320 and A6-6420K microprocessors are based on older "Piledriver" architecture. Both chips come with 1 MB L2 cache and 65 Watt TDP. The A6-6420K offers 100 MHz higher maximum Turbo Core speed than the A6-6400K, and we suspect that its base frequency is also 100 MHz higher. The A4-6320 is listed with 3.9 GHz maximum clock, that is the same as the A4-6300, which is either incorrect, or the APU has some other enhancement or enhancements that make it faster than its predecessor. Pre-order prices of the A4-6320 and A6-6420K are $57.30 and $78.50, and those are very close to current prices of A4-6300 and A6-6400K in the same store.

All new processors should work in socket FM2+ motherboards. Since future dual-core Richland and quad-core Kaveri parts were listed simultaneously, we suspect that they will be launched together. Listed below is a summary of APU specifications:
