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

Remember that AMD’s Bulldozer architecture added hardware acceleration for AES encryption and decryption, and this naturally carries over to Piledriver. Basically, this capability is bottlenecked by memory bandwidth—the faster you can feed the CPU, the better it performs in the AES-256 benchmark.

After running a handful of spot-checks on performance, we decided to use 16 GB of DDR3-1600 memory instead of 8 GB of DDR3-1866, particularly since the RAM drive we use for alleviating storage bottlenecks would carve some of that memory away anyway, and the extra bandwidth did nothing to speed up our results. Nevertheless, FX-8350’s loss to FX-8150 is a result of that lower data rate. Had we used DDR3-1866 modules, the FX-8350 would have matched the Ivy Bridge-based chips at DDR3-1600 closer to 20 GB/s.

It doesn’t appear that Vishera’s cache latencies—often thought to be one of Zambezi’s performance issues—are any different. AMD's architects confirm the L3 isn't changed. The L2's minimum latency isn't any different, either. But average L2 latency should drop as a result of optimizations.

    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.

    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!

    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? ;)

    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.

    looniamsorry 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!)


    You seem to forget that unlike Intel's Ivy compared to Sandy, Vishera versus Zambezi leaves Vishera the superior overclocker as well as cooler-running and with superior overclocking price/performance ratios. There's also the fact that AMD did this on the same process node, not that that matters as anything other than a foot note.

    Just imagine if this would have been BD? Less people issed off'ed and us AMD/competition fans would have been happy with AMD's offering.

    Honestly, I'm disappointed in Vishera. Comparing it to Trinity, it seems that the L3 cache doesn't actually make a difference in performance for these chips. Maybe its L3 cache's latency is simply too high for it to do much of anything other than suck power. Some CPU/NB frequency overclocking tests might be able to confirm this and if so, solve the problem and let Vishera really pull ahead of Zambezi and Trinity.

    One really big one. Kept me up till 5AM this morning ;-)

    So AMD FX-83xx will direct compete with I5-35xx........ (both in term of price and performance)...

    Anyway it good upgrade for owner with am3+ board... (including me :D , add another item in wish list)

    If you are paying that much, why would you let it set idle, turn it off instead!

    i realy wish to know how 8350 compete against my 2700K, to bad they had only 3700 series in there....
    But wow! at only 195$ this 8350 looks like a clear winner! Nice Comeback AMD !

    Not bad at all, considering. There may be hope yet for AMD. :D

    It really isn't a cut & dry black & white situation. Depends on the workloads and purpose...

    too bad they didn't open up with a lower price as the article hinted at.

    for now i'll pass. if it was truely under $200 i would consider it for my next low end system, but so far the price is well over $200 and not worth it.
