  How much would that run for 5K?
  • brians 7y ago
    Probably. Or AMD pulls another rabbit out and calls it $2500 in mid 2021.
    • bitL 7y ago
      I doubt it. This is new AMD with ridiculous prices when they face no competition. I'd say it's more likely to expect $6k than $2.5k.

        I don't really see how the pricing is ridiculous though. They're still way cheaper than what Intel charged for the same cores a year ago, and they have more cores than Intel can even offer on their best workstation chips. If you compare against 28 core Xeons, the new Threadrippers are a downright bargain.
        • bitL 7y ago
          I meant in comparison to what we were used to. Now a semi-decent TRX40 board is $700, entry-level TR3 is $1300. Top-end x399 board is $550, entry-level TR is $250. There was a huge jump in prices compared to previous generation of HEDT.
          • barkingcat 7y ago
            This comment doesn't make sense. You're getting more cores than previous generation of HEDT, and the equivalent Intel processors aren't cheaper at all. This is a new market segment. If you want a fast cpu, the Ryzen 7 and 9 series are completely fine if you want that price range! The exact same price range as you're used to still exist. On the other hand, people have been used to paying exorbitantly for Xeon processors, like 2000-5000 per cpu, so this is a breath of fresh air.
            • bitL 7y ago
              You are getting the same number of (better) cores for higher price. But backwards/forward compatibility is gone, so you either pay the full price upfront, or are stuck with outdated chips forever.

            Board cost is due to PCIe4 support mainly
            • bitL 7y ago
              Which is kinda unnecessary as there is no single GPU on the market capable of saturating PCIe3 and situations where one needs a sustained transfer between multiple M.2 SSDs that could saturate PCIe4 are very rare. Only 100Gbps+ LAN is probably practical for a few total pro users.

                Actually, its pretty easy to get bandwidth-bottlenecked in GPU-compute. I know video games don't really get bandwidth bottlenecked, but all you gotta do is perform a "Scan" or "Reduce" on the GPU and bam, you're PCIe bottlenecked. (I recommend NVidia CUB or AMD ROCprim for these kinds of operations) CUB Device-reduce is extremely fast if the data is already on the GPU: https://nvlabs.github.io/cub/structcub_1_1_device_reduce.html https://nvlabs.github.io/cub/structcub_1_1_device_reduce.htm.... However, if the data is CPU / DDR4 RAM side, then the slow PCIe connection hampers you severely. I pushed 1GB of data to device-side reduce the other day (just playing with ROCprim), and it took ~100ms to hipMemcpy the 1GB of data to the GPU, but only 5ms to actually execute the reduce. That's a PCIe-bottleneck for sure. (Numbers from memory... I don't quite remember them exactly but that was roughly the magnitudes we're talking about). That was over PCIe 3.0 x16, which seems to only push 10GBps one-way in practice. (15Gbps in theory, but practice is always lower than the specs) Yeah, I know CPU / GPU have like 10us of latency, but you can easily write a "server" kind of CPU-master / GPU-slave scheduling algorithm to send these jobs down to the GPU. So you can write software to ignore the latency problem in many cases. Software can't solve the bandwidth problem however. You gotta just buy a bigger pipe.

          They increased pricing by $100/$200 for 24/32 core CPU since last year. May be it's not ridiculous, but they are not undercutting anymore.
          • aoeusnth1 7y ago
            They are undercutting - on perf/$. The difference in sticker price you pointed out is only there because there is no comparable intel part (under $3000 at least)
      • lliamander 7y ago
        Yup. What's crazy is that a $6k 3990X is still a better deal in terms of $/core than even a dual-cpu Xeon W-3175 system (which would cost about $6k for only 56 cores).
  • chaosbutters 7y ago
    probably closer to 3500-4000 USD. Maybe $5k if theyre feeling greedy. But I think they want to undercut intel so theyll keep their margins reasonable so they can crush the Xeon line
