![]() On the other hand, I decided I can afford the premium, and also hope I can keep a 3700X without upgrading a bit longer than I would have donewith a 3600, levelling out the cost per time unit a bit. Therefore, 3600 seems like better performance per dollar (I think that is the conclusion from reviews I read as well). I am also not sure how well SF strength scales with more nps.įor other applications, there seems to be an increase in performance for 3700X compared to 3600 between 10-30 % (except for a few cases, like Winrar, I think it was). On the other hand, spending over 60 % extra to get some additional nps in SF (likely not more than 30 %) didn't seem like well spent money. Sorry if I wasn't clear, but at least going from 4c/4t to 6c/12t will from what I understand make a difference for Stockfish, and also for the editing and so on. I also don't think it is worth paying $150 extra for a 3700X to get some more nps for Stockfishīut if you don't care much about the speedup from the extra cores, then what's the point in spending the money to upgrade at all? If that would not be the case, I would in other words have to go with two 2070 super two get SLI (which is not always scaling well) a substantial price hike. I don't plan on gaming much, Lc0 is the main purpose. They are at least $80 more expensiveĪs a last note, SLI for the RTX 20xx series is not supported for 2060, 2070 or 2060 super. In order to be prepared for my future plan, this means I have to choose a card that operates at 8x/8x, which basically will be those that support SLI. the mobo might actually be bottle necking for two CPU. There are tests for RTX 2080 (might have been Ti) that have shown a performance decrease when the card has been operated at PCIe 3.0 8x, equivalent in bandwidth to PCIe 4.0 4x. The problem is that these will operate at x16 and x16/x4, not at 8x/8x. In order to support two video cards, I thought it should be fine because it has two 16x PCIe 4.0 slots. Just to let you know again, in the hope that I can advice someone to not make the mistakes I have made:Īnother thing I noticed is that the mobo I intended to buy (aorus elite) has a suboptimal setup for my intended purpose. 1000W might have been an option if I had decided on 2xRTX 2080, but that has never really been more than a distant dream for me! I found an online calculator, that gave 750W I think, even when choosing a bit higher-speced hardware. In the end, I think I might have been ok with 750W, but 850W should be totally fine. I was debating with myself whether to go for 750W, 850W or 1000W. With undersized, there can also be more noise, which is more annoying for most people, me included. The main problem with slightly oversized PSU seems to be sub-optimal efficiency. I think its better to have a slightly oversized PSU, which gets little bit cooler, than a PSU used to it's max limitation. Electronic components ages faster if the temperature goes up. I assume the heat it produced, was in the long run the cause. The PSU was at that moment a couple of years old. The only hardware problem I have during many years and many computers, is a broken PSU. "Skimping on the PSU seems unwise, but 1000W seems to be PSU-underload." In that case I am at least a bit more future proof, hopefully (who knows what happens in computer business). But perhaps this won't matter at all with RTX 2060. ![]() I am not sure if this matters in practice, though, because I don't know how exactly data is shuffled over the PCIe bus.Īnyhow, I'd say a mobo with support for 8x/8x instead of 16x/4x seemed worth the money for me. Here is the first article I found by googling: Leela is not bottlenecked by the bus, but a fast GPU might very well be, and therefore Leela might be bottlenecked by the GPU. If pointed out as a side note that if I were GAMING, SLI (or NVlink for the the high-end RTX 20xx-series) might be an important option, although sometimes it scales well, sometimes not. But I think I wrote the opposite, that I can do fine without (with two RTX 2060, which do NOT support SLI). If I did, it was a mistake, sorry for that. When did I say SLI is needed for Leela? I don't think I mentioned it. SLI is a graphics tech, there are no scanlines to draw in a chess engine. You don't need SLI for Leela AFAIK, nor is Leela going to be bottlenecked by the PCIe bus.
