The binning on 3950x chips is nothing extraordinary, thats why the chiplet model is so powerful, because you don't need to have 16 perfect cores on one die to sell the CPU.
- ajross 7y agoThen why are there so few of them? You can't buy these things anywhere, despite being priced at a volume level. Something doesn't add up.
- kllrnohj 7y agoWell, the 3950X just launched, so there's a demand spike that's going to follow from that. But that aside these are sharing parts with the Epyc series. If AMD is getting volume orders for Epyc that is definitely going to take priority. The allocation order is going to go enterprise first, system builders second, retail boxes a distant 3rd.
- ajross 7y agoThe Epyc devices are lower binnings though! That's exactly my point. They don't seem to have the 3.5+ GHz parts available in a reasonable quantity. When Intel was doing this with "1 GHz" Pentium 3's way back when, they got crucified for a paper launch.
- reitzensteinm 7y agoAre you sure they're lower binnings, or just equally good chips being run more slowly for reduced power consumption? The power budget per core on Epyc is quite a bit lower.
- kllrnohj 7y agoThe 3700X and 3800X, both of which have higher base frequencies than the 3950X and also use 8-core chiplets, have been in stock near continuously since launch.
