AMD's new Piledriver core technology should not be a surprise to any enthusiast as much of its "embargoed" information has already been exposed on the Net. Today we take the AMD FX series model 8350 desktop variant, code named Vishera, and look at it in an enthusiast way as we expose its IPC at 4GHz, and a bit of overclocking.


As computer hardware enthusiasts, we all love to see advancements in core architecture technology. Sometimes we find it exciting and other times we find it almost depressing. AMD has not lead in the excitement category for a while now. Its last major desktop release was that of the FX-8150 "Zambezi" processor, based on its Bulldozer core technology. Zambezi was far from compelling for the enthusiast. We will see today if that changes.

As we have in the past with new CPUs, we have put the new AMD FX series Vishera processor through the paces at 4GHz, compared to Intel's Ivy Bridge and Sandy Bridge cores, as well as AMD's Bulldozer core, the Zambezi. In this day of highly dynamic clocks, better known as "Turbo" cores, we think that holding our test processors at a specific clock and comparing is best for the overclocking enthusiast. After all, HardOCP readers are most likely to use their processors at a specific clock rate in an overclocking scenario. Showing you what to expect at equal clocks will let you know what kind of performances you should see at the clock rates you would likely run comparatively.

As presentations from AMD go, this was the lightest reading I have seen from it in the last 15 years of doing this job. AMD proclaims that the customers of its FX series of processor want unlocked processors, with the "latest tech and world's highest frequencies," and up to 8 CPU cores.

The new FX-8350 Vishera packs in a full 8 cores (no HyperThreading here), 1.2 billion transistors at 32nm, in a 315mm^2 package. We will see AMD release 6 and 4 core variants as well. AMD has made more than a few advancements as are laid out below for your viewing pleasure.

Pricing and parts are laid out below in a table that places AMD's parts against Intel's price competitive processors.

Given the performance you see on the following pages against the overclocker's favorite Intel cores, you will see why AMD has priced its new FX series Vishera processors as it has.
