AMD puts Excavator on the desktop with the Athlon X4 845

AMD had some announcements to make at CES regarding Socket AM4 and a new, quieter boxed cooler called the Wraith. While new CPUs and APUs for Socket AM4 remain under wraps, AMD is introducing three new processors for Socket FM2+ today, along with two new boxed heatsinks that are meant to bring Wraith-like performance to more processors.

The most powerful chip we're looking at today is called the A10-7860K, which slots in beneath the range-topping A10-7870K. This APU is part of the Godavari family of chips, and it boasts four Steamroller cores clocked at 3.6GHz base and 4.0GHz boost speeds. Those speeds are almost identical to the beefiest Kaveri APU, the A10-7850K. The 7860K's eight GCN graphics compute units get a 37MHz bumpĀ over the 7850K to 757MHz, though, and the 7860K also slips into a relatively frugal 65W TDP versus the older chip's 95W thermal envelope. This chip will carry a suggested price of $119.99.

At the entry-level range of the APU lineup, AMD is introducing a dual-core part called the A6-7470K. This chip comes with two Steamroller cores clocked at 3.7GHz base and 4.0GHz boost speeds, along with four GCN compute units clocked at 800MHz. It'll slot into a 65W TDP. AMD didn't reveal pricing for this chip.

The most intriguing part AMD revealed today is the Athlon X4 845. This CPU features four Excavator cores, as seen in the Carrizo APU lineup. Those cores are clocked at 3.5GHz base and 3.8GHz boost speeds. Like other Athlon chips, the X4 845 has no onboard graphics capabilities, but it's pretty affordable at a suggested price of around $70. One limitation of this chip is that it only offers eight PCIe 3.0 lanes direct from the processor, but that may not matter for the kinds of value-oriented system builds AMD is targeting with this part.

Along with the Wraith cooler, AMD is also updating its boxed cooling solution for a couple of its other processors. The A10-7860K and Athlon X4 845 will both come with what AMD is calling a "quiet 95W thermal solution." This cooler uses a Wraith-inspired fan and a couple heatpipes to deliver performance that AMD describes as "similar" to the Wraith. A less-fancy updated cooler with a similar fan will ship with the Athlon X4 870K and Athlon X4 860K CPUs, as well as the A8-7670K and A8-7650K APUs.

The Wraith cooler itself will begin shipping exclusively with the FX-8370 CPU for $199.99. A lower-priced version of the FX-8370 without the Wraith in the box will also be available for those who want to use their own thermal solutions.
