AMD Launches A10 7860K & Athlon X4 845

Despite being stuck on the 28nm node for the past while, AMD has been working to bring more CPUs to consumers with better binning and performance as the process and technology matures. Case in point is the A10-7860K Godavari and Athlon X8 845 Carrizo chips launching today. Both chips are focused on increasing performance/watt either by using a new architecture design or simply better binning and process improvements.

AMD Excavator Carrizo

First up is the 2M/4T Athlon X4 845, a 65W Carrizo part based on of the “Excavator” architecture. As expected of an Athlon part, it does not have an iGPU and uses the FM2+ platform with DDR3 and PCIe 3.0 x8. As the sole desktop Excavator part, the chip is a bit of a curiosity with only 2MB of L2 instead of the usual 4MB but still manages to have a higher IPC due to improved pre-fetch, large L1 cache and better branch prediction. The low power nature of Excavator also limits the clock speeds to 3.5-3.8Ghz.AMD Excavator Carrizo 2

Next we have the A10-7860K which is a Steamroller based 2M/4T chip with 512 GCN Stream Processors. With a 3.6-4.0Ghz clock speed, the chip places lower than the 7890K and 7870K but it comes in with a 30W lower TDP at 65W. Despite the lower TDP, the 7860K will get the 95W cooler which should make it a good choice for an HTPC/budget gamer. Overall these chips should tide AMD over till more Excavator and Zen based APUs hit later this year.
