The first APU based on Piledriver, codenamed Trinity, debuted last spring; the desktop variant hit shelves at the beginning of this month. In our conclusion to last year’s FX review I wrote the following:. Retrieved 6 January These chips are obviously much larger than Intel’s 22nm Ivy Bridge parts, but Intel has a full node advantage there which enables that.

Komodo was to launch in on the FM2 socketbut this never happened. Following Bulldozer’s mediocre reception, AMD insisted that the new architecture was still young and would serve as a “solid building block” for the FX series. I’ll go find a place where an FMA3 should work and see what happens. All of the FX processors remain unlocked and ship fully featured pilledriver hardware AES acceleration enabled.

Moving to gaming piledriber we tested out two contenders in three games today; Crysis 2, Counter-Strike: Add your comment to this article You need to be a member to leave a comment.

In 7-zip we have an piledrkver percent gain, and in the SunSpider benchmark we have the largest advantage shown in our testing, a whopping 12 percent. As a fabless semiconductor manufacturer, AMD is now at GF’s mercy when it comes to moving process technology forward.

Piledriver (microarchitecture) – Wikipedia

Poorly threaded web based tests like the SunSpider and Chalkboard benchmarks showed much larger gains than well threaded tests like our wPrime and Truecrypt benchmarks. Unfortunately, Bulldozer wasn’t all it was cracked up to be. Piledriver is a light evolution over Bulldozer, so there’s actually no substantial increase in die area compared to the previous generation.


Piledriver uses the same “module” design. If you have a hardware performance question or an interesting data set Thomas has you covered.

Vishera is still built on the same 32nm GlobalFoundries SOI process as Zambezi, which means there isn’t much room for additional architectural complexity without ballooning die area, and not a whole lot of hope for significantly decreasing power consumption.

Piledriver is a bit more power efficient than Bulldozerwhich enables AMD to drive Vishera’s frequency up while remaining in the same thermal envelope as Zambezi. Join thousands of tech enthusiasts and participate.

AMD’s Bulldozer core compared with Piledriver

Across the board Vishera ships at higher base frequencies than the equivalent Zambezi part, but without increasing max turbo frequency in the case of the 8-core parts. Early x86 bit Am To make matters worse, before AMD could rev Bulldozer, Intel already began shipping Ivy Bridge – a part that not only increased performance but decreased power consumption as well.

About this time last year, AMD’s new Bulldozer-based FX series launched to bright-eyed system builders who expected the new architecture to challenge Intel’s increasingly comfortable position in the upper-end processor market.

From the Wikipedia link you can deduce that this is because the FMA4 variant was actually implemented before FMA3 so the previously defined fma4 identifier couldn’t simply be dropped or it would break existing applications.

All these similarities make it easy to compare TDPs pilecriver clock speeds between the new parts and the old:. Multiple executives have fled the company, margins have tumbled, and long-term prospects are dim, at best.

Thomas Ryan Author at SemiAccurate. The FMA4 instructions are a lot more efficient for my purposes, because I didn’t have to write over any operand.
