They're not just adding more cores on because the processes have improved allowing for more on the same silicon.
The complexity of the chip is higher than the previous models, with three dies under the hood instead of one. The high end chips are closer to Threadripper than they are to the models they're replacing.
I think $750 is still a ridiculously good price, and Intel's feet are being held to the fire.
- celrod 7y agoThe 1950X cost $1000 2 years ago, and it looks like you can pick them up for $500 now. Both are 16 cores with two chiplets. 1950X advantages: - 4 memory channels vs 2 - 64 PCIe lanes vs 16-4-4 3950X advantages: - 64MB of L3 cache vs 32MB - DDR4 3200 vs DDR4 2666 - The PCIe lanes are 4.0 vs 3.0 - 3.5Ghz base clock vs 3.4 - 4.7Ghz boost clock vs 4.0 - 15% better instructions per clock - Full avx2 instead of emulating with two 128-bit units - 105W vs 180W TDP The 3950X sounds like quite the improvement! Definitely a great deal IMO.

- CoolGuySteve 7y agoThe biggest difference between the 2 imo is that TR4 boards have 8 DIMM slots whereas Ryzen maxes out at 4 even with X570 afaik. Ryzen 3000 specs say it can support 128GB of ram but it’s hard to find 32GB DIMMs on the market. So if you’re trying to build a workstation with lots of ram and more than one GPU, the Ryzen boards are too limited even if you’re willing to buy a nice one.
- penagwin 7y agoI think they've got the market segmented decently. Ryzen's the consumer chip after all, and it's high end configuration boarders on prosumer for sure. I feel like if you're requiring 128GB of ram and/or maxing out the PCIE then you're going to have a bigger budget and ThreadRipper makes more sense.
- sekh60 7y agoCrucial makes 32GB DIMMs with ECC memory, not sure if non-ECC. Many Ryzen mobos accept ECC memory.
- dis-sys 7y ago> I think $750 is still a ridiculously good price Threadripper 1950x comes with the same core count, more memory channels, more PCI-E lanes and more memory. You can grab one for $499 from amazon.

- reitzensteinm 7y agoThat's the last product they have which contains the original Zen dies. They are probably just liquidating the remaining stock. I wouldn't make the assumption that AMD could sustainably sell that much silicon at that price point.
- lhoff 7y agoBut you have to pay around 150$ more for the Mainboard and a threadripper compatible cooler is also quite expensive due to the huge size of the CPU. So you're not going to save more then a few bucks but get a slower and outdated CPU.
- consp 7y agoMost high end AM4 Motherboards have sufficient clearance to allow a TR cooler with an adapter plate on the AM4-MB so buying one for a later upgrade might be possible. Note: I have a TR cooler running on my AM4 board (custom loop though so not completely comparable) and there is more than sufficient space to place it.
- sangnoir 7y agoYou can't use an AM4 motherboard[1] with the 1950X - you have to use an X399-chipset/TR4 motherboard, which cost more than AM4 boards (and likely have adequate room for TR coolers)
- consp 7y agoThis was as a response to the idea of using a ryzen as alternative to a 1950 and solving possible thermal issues if they would occur. I never mentioned using a TR on an AM4.
