AMD FX-8350 Review: Does Piledriver Fix Bulldozer's Flaws?

By AMD 

Last year, AMD launched its Bulldozer architecture to disappointed enthusiasts who were hoping to see the company rise to its former glory. Today, we get an FX processor based on the Piledriver update. Does it give power users something to celebrate?

Benchmark Results: The Elder Scrolls V: Skyrim

When AMD’s Bulldozer emerged, we were particularly disappointed that it wasn’t able to resolve the performance deficits suffered by AMD's older architectures in processor-bound games. In fact, our Skyrim tests demonstrate that the FX-8150 underperforms a Phenom II X4 980 across the board, even at 2560x1600.

The Piledriver-based FX-8350 does not completely ameliorate AMD’s gaming issues, but it does improve on the Bulldozer architecture, at least pushing past the Phenom II flagship.

I presented AMD with my findings and we came up with a couple of sources for the speed-up, which, combined, likely explain what’s happening. Most obvious is the 400 MHz-higher base clock rate, enabled through power optimizations. Second is Piledriver’s larger L1 DTLB (from 32 entries to 64), which can benefit performance when a game searches through large data structures spanning multiple pages.

At the end of the day, AMD still has work to do in improving game performance. But Piledriver certainly does help rectify the slide backward we saw Bulldozer taking relative to some of AMD’s previous quad-core parts in processor-bound games.

    Looks like AMD did pretty well with the 8350.

    I now really don't see people purchasing it though....people will be buying the 8320.

    Interesting, nice improvement over BD, it spars very closely or beats the i5-3570K sometimes, It really can't compete with intel's high end, but nevertheless good job AMD!

    AMD is doing good with the pricing this time. This is what AMD should be: aggressively priced CPU with added features.

    The price is actually nice this time. Hopefully AMD sticks around and gives good deals like this for years to come.

    Nice job AMD. It just kept itself afloat! Not performance killer, but good enough to get a chunk of desktop sales just in time for the holiday season. Probably wouldn't buy it over an Intel system because most apps are still quite single threaded, but I would certainly consider it. Welcome back to the race AMD. Keep up the good work!

    so... amd will still keep my local electric provider happy. Good job AMD but I think FM2 APUs are more promising. The fact that APUs alone can win against intel processors if discrete graphics is not involved. Perhaps AMD should focus in their APU line like integrating better gpus in those apus that will allow dual 7xxx graphics and not just dual 6xxx hybrid graphics. The entire FX architecture seems to have the issue with its high power consumption and poor single-thread performance. Better move on AMD...

    I would have liked to see more Intel offerings in the Benchmarks. Say an i3-2120 & i3-3220 for comparisons sake as they'll be cheaper than the new Piledrivers.

    If more games / daily use apps start using more cores these new AMD's could really take off.

    Interesting. Probably not a gamers first choice but for users who regularly use multi-threaded programs, the 8350 should be very compelling. About $30 cheaper than a 3570K and can be overclock as well, video/photo editors should really consider this. It doesn't beat current Intel CPUs in power efficiency but at least it's significantly more efficient than Bulldozer.

    Thanks for the review.
    Btw Chris, how many cups of joe did you had to take for the overclocking testing? ;)

    sorry just not overly impressed.
    5-12% performance increase 12% less power - sound familiar?
    the only difference this time was less hype before the release. (lesson well learned AMD!)

    I think the fx-4300 is going to be the new recommended budget gaming processor. Good price that is only going to get lower, and it has overclocking.
