    Thanks OP.

    Looking to build a new pc soon. Can anyone comment on whether they would go for the i9-9900 which goes for a similar price?

    I've always been an Intelboi but AMDs recent offerings has me tempted.

      If it helps, I've always been an Intelboi as well but these newest AMD just are incredible performance to price point. Their value is just shocking. Feels like Intel has just been slumbering while AMD has been trying to catch up, and now Intel is being forced to play the catch up game. Loving the competition between the two and how ultimately its us, the consumers, winning from this competition.

      My next build will definitely have an AMD at this rate, granted gaming doesn't really need it, but being an Ozbargainer, I feel like it's only right to go for the biggest bang for the buck.

      In my opinion Ryzen 3900x>I9 9900 if similar price as they have comparable performance single core but the 3900x just edges it out in multi core. They're that similar that I would just be looking at which comes in a better price once you factor in a motherboard.

        Actually the 9900 boosts to 5.0ghz at single core uses, so that's about 8% there. I agree it's a tiny difference lol but benchmarks show the 9900 coming out ahead for single core (mainly gaming) uses. The coolest thing for the next gen of graphics cards is having pci-e 4 that the Ryzen supports! Exciting times ahead!

        • Actually the 9900 boosts to 5.0ghz at single core uses, so that's about 8% there.

          Clock speed alone does not equal performance. Instructions per clock are higher on Zen 2 depending on the task, but there was about a 5% gap for average game benchmarks in Intel's favour at launch.

          The 3900X remains far better value, and I'd recommend you steer clear of UserBenchmark when forming your opinions.

            @jasswolf: Hey can you point me in the direction of something easy and clear to read about the Instructions per Clock on Zen 2? What I am mostly seeing is about how it excels with multi-core, but don't really understand how that even works haha.

            Also, sticking to benchmarks from hardware testing groups/websites about AAA games or other specific tasks you want the computer for is definitely the way to make an educated opinion when deciding between parts.

            I too would recommend to stay away from any benchmarks that do not document the process, hardware and software run properly - never even used UserBenchmark, but that just looks sketchy AF

      For strictly gaming the i9 has a slight edge (unlikely you will even notice in the real world). For everything else (most productivity) the 3900x has a pretty significant advantage. I'd be going the AMD if it's a similar price.

    • You would be wasting your money on a 9900. If you look at the platform as a whole it's pretty much a dead end in terms of upgrade path. At least with the 3900x you have an upgrade path when the 4000 series comes out next year. At the moment the 9900 has slightly better gaming performance, before all the Intel security hole patches, if every fps counts on certain games. However when the new Ryzen based Xbox and PS5 come out more games will be optimized for AMD. You are also conparing a 12 core AMD processor vs an 8 core Intel processor. The 3900x has a significant advantage in productivity workloads due to the additional four cores.

      • do people actually upgrade CPUs a year later?

        • +2

          The point is that you have an upgrade path to a better CPU, whether you buy it in a year or later. The AM4 socket has been supported by AMD since 2017. It will support four generations of Ryzen processor. Intel generally force you to upgrade every two generations or less even though the 9900 is based on the same Skylake architecture since their 6000 series. The money you save on a motherboard etc. could go towards a better Graphics card or more storage.

        To be honest though, the CPU plays such a minor role in 1080p gaming - you only really start noticing differences between Intel and AMD in gaming at the 4k and multi-monitor setups.

        Not even sure if games bother optimising for CPU use to be completely honest. Is there much evidence of that out there? I am happy to read whatever you have found on that topic though to be better informed myself!

        Also, the PS4 CPU was AMD too, but I haven't seen any AMD optimisation in games since it's release. Agree though that with PS5 and the next Xbox - that will give more incentive to developers to optimise whatever they can for the AMD CPU in those consoles, but these optimisations likely will have not much significant gains in the realm of PC high-end gaming which depend a lot more on a well balanced hardware setup (GPU, RAM, mobo, storage) as a whole rather that narrowing down to Intel vs AMD for the CPU.

      • 4000 series will use a new socket

        • No it won't. AM4 is supported till end of 2020 and 4000 series is coming out in 2020. Why don't your read up on what AMD has stated before posting such a comment.

    • Really depends on your budget and planned resolution. For instance if you have $1500 to spend for the total system cost then dropping $400+ on a CPU isn't going to be the best strategy as you'd then have to downgrade your GPU a tier or maybe make a trade off elsewhere in the system.

      In general you're going to find parts that are best bang for buck in any given price range. Once you've set your budget then there's plenty of communities out there that can tell you what the best options are in your price range. Reddit's /r/buildapc and /r/buildapcforme are good for that.

    • if you're purely gaming, i9 is still king.

      if you do other things as well intel loses their lead.

      • I9 currently has the advantage in certain games at 1080p. Once you go to 1440p and 4k there is no advantage. If you are spending $700 on a processor it's unlikely you are going to pair it with a 1080p card like a 1660 or RX580. You will most likely pair it with a 2070 Super or 5700xt and above to play at 1440p and 4k.

  • Any deals for 3800x?

  • bah, just bought 3700x from umart for 515, oh well

    • same here (umart) last year with a 2700x and prob the same next year when i upgrade 4700x. oh well

  • I didn't think this code included Computer Alliance.

  • -1

    Code doesn't work.

    • Still working fine for me, its only for selected products.

  • Isnt the Ryzen 9 or I9 a bit overkill for gaming?

    If I was getting it, I would be pairing it with nothing less than an RTX 2080 Super or Titan.

    The Ryzen 7 is better to go with and to pair with 5700 XT or RTX 2070.

    I went with an Ryzen 5 3600 and RTX 2070 Super, seemed like the best deal for a midrange build at this time.

  • When do you guys expect a similar deal/price to happen again? Trying to decide between a 3700X, 3800X and 3900X. I would much prefer the 3900X if the price is around $650 or so.
