![]() ![]() ![]() ![]() I’ve put a lot of thought into this, but am not quite sure where to go with it yet, especially after you made mention of the Ryzen series being less optimal than the Xeons. When comparing the E5-2600v3 series vs Ryzen 3000 series, the current cost of equipment was approaching a relatively comparable range, while power costs for the Ryzen series would be relatively favorable over the 7 years of lifetime. The GFLOPS values are from the website, under CPU Statistics, and the power consumption values are from review websites.īasically, I was looking at the total expected cost of ownership, and seeing which route would be less expensive. It would be expected to consume 95W x 10 for the builds, with around 30 GFLOPS per machine. I had done a comparison of keeping the equivalent performance characteristic, and using up to (10) E3-1240v3 machines, but the expected electrical efficiency would be prohibitive. (I am assuming that the v3 is so inexpensive now, compared to the v4, due to the specter/meltdown performance penalties.) It would be expected to consume around 240W x 2 for the builds, with around 125 GFLOPS per machine. I would eventually wait for the v4 or v5 server CPUs to come down in price on eBay before doing a complete overhaul. Two E5-2600v3 builds within a year of each other, likely with single socket boards using an E5-2695v3. It would be expected to consume 240W x 2 for the builds, with around 160 GFLOPS per machine. Two Ryzen-based builds, around the %950X, with one built within a year, and another built a couple years after that, with the above lifecycle, before doing a complete overhaul. One of my personal requirements is to use ECC RAM, as I’ve gotten quite used to having it, and have experienced less issues with Win7 and FreeNAS All of them have the idea of a 6-7 year life cycle between complete overhauls. I have looked into at least a couple idea for this next build. I'll likely pick up a 4900x or whatever the next-to-best Zen 3 chip is to run a few GPUs with next winter.Īs in all of life, budget dictates action, both in initial outlay and the ongoing expenses, so I completely agree with you and just wanted to add my thoughts.Īs this is a long-term part time of my family’s philanthropic arm (we’re not particularly rich, but are completely without debt) the budget allocation includes both the hardware cost & upkeep, along with average electrical & (summertime) HVAC costs. On the other end of the spectrum, my single R540 with one 18 core CPU cost much more and probably isn't too much more productive than a 3950X, but was a long term purchase and can handle loads of RAM. However, an R620 with dual 8 cores and ram could probably be had for less than a 3900x now days. I like dual sockets for 2x CPUs per OS install and supporting components, but my dual socket 8 core IVB Xeons could probably each be replaced with a 3900x with minimal losses of productivity and some reduced power draw. Having 12 or 16 cores in a consumer package is really only limited by the ram bandwidth and scalability. Ryzen 9 is making that line much more narrow. While I generally agree and run a Xeon farm myself. If your devices are running hot, and you can't add cooling, you can reduce heat by limiting the amount of CPU BOINC is permitted to use.ĭoes this sidebar need an addition or correction?
