The 1700 is really well placed, often seems to beat the i7 7700k in benchmarks whilst drawing less power and costing roughly the same/cheaper. Probably even better value if the stock coolers are as solid as they sound. Definitely going to be a popular chip with gamers (I'm very tempted myself). Hopefully more software starts to make use of multiple cores more effectively. It's not like it's a new feature of chips any more.

    Doesn't Prime95 use AVX2 and FMA3 since version 28.5, which pushes Intel's power consumption higher? Can that be disabled?
    - jhasse 10y ago
      Yes, that's probably the reason for the increased power consumption. But Ryzen also supports AVX2, doesn't it?
      - tutanchamun 10y ago
        Ah yeah, remembered it false. I thought Ryzen had no AVX2, but actually it has it, but at half the speed.

        Half the width, 128bit vs 256bit. Often translates to half the speed but not always.

        Ryzen is half as wide, but executes at full speed. Intel drastically reduces clockspeeds when executing AVX. http://www.intel.com/content/dam/www/public/us/en/documents/white-papers/performance-xeon-e5-v3-advanced-vector-extensions-paper.pdf http://www.intel.com/content/dam/www/public/us/en/documents/...

  I haven't found one yet, but as the chip is rated at 65W and the i7 7700k at 91W, it's pretty likely to draw less (at load anyway). I'd be curious to see what they draw whilst idle though.
  - robotmay 10y ago
    After having a look at some of the links posted, it looks like the power draw is slightly higher than the i7 7700k in most tests, although lower in some. Looks like my assumption based on the TDP was a bit off (also my misapprehension that TDP is power draw, whoops) :)
    - rockdoe 10y ago
      Thermal output = power draw is correct though.

Especially in games i think it's pretty clear that even the 1800X is not amazing, really good, but behind a 7700k while being more expensive. If you are not solely a gamer though, it's the better choice!

  According to AMD CEO Lisa Su at https://www.reddit.com/r/Amd/comments/5x4hxu/we_are_amd_creators_of_athlon_radeon_and_other/def5iab/ https://www.reddit.com/r/Amd/comments/5x4hxu/we_are_amd_crea... : "there are some games that are using code optimized for our competitor... we are confident that we can work through these issues with the game developers who are actively engaging with our engineering teams." Also, another AMD employee chimed in: "But what's also clear is that there's a distribution of games that run well, and a distribution of games that run poorly. Call it a "bell curve" if you will. It's unfortunate that the outliers are some notable titles, but many of these game devs (e.g. Oxide, Sega, Bethesda) have already said there's significant improvement that can be gleaned. We have proven the Zen performance and IPC. Many reviewers today proved that, at 1080p in games. There is no architectural reason why the remaining titles should be performing as they are."

Unfortunately you can bet Intel is going to put all the spin they can into "AMD underperforms for gaming", while the software game developers are going to slowly optimize for Zen, up to the point where this perf discrepancy will be fully fixed but people will still have the mindset that "AMD unperforms for gaming"... sigh

    In what ways can games be optimized for Intel? What is the sort of change that the game developers would need to make to increase performance on AMD?
