Many people are hoping for a cut down cost of the new 8 core or 5700x to bring some kind of cost reconciliation of the new zen3 8c part to the old zen2 8c part. Below is why I don’t think there will be a 3700x equivalent to the new zen3 8c part.
the simple reason is that there is no incentive for AMD to charge less for their 8c sku. The zen3 ccd is a different animal to zen2. Zen2 is two 4c CCX out together so you can have poor quality CCX being lumbered together with a high quality 4c and to cut cost. In the zen3 8c CCX you don’t have that option. All the cores in that 8c needs to be quality so that certainly means the fabrication is more heavily binned against 5600x and 5900x where 6c per CCX means a less successful CCX can still be made into product therefore less “throw away” and more cost effective.
I think the pricing of 5800x is higher per core than the 5950x also makes sense as they have to use really high binned CCX for 5800x to ensure the boosts are hit on a single CCX where in 5950x they have 2 CCX/CCD so one of them is your high bin one and the other can be slightly lower ranked one and still able to sell as a 16c part without falling foul of the advertised boosting.
I think as the TSMC 7nm process matures and their yields get better there may well be a situation there are less less 6c/CCX skus available as there are more successful 8c/CCX part and that’s why you will see potentially diminishing supply of 5600x and 5900x and pricing of 5800x starts to reduce.
on 5600(non x) or some kind of 5400 (4c) sku, those parts will most likely to exist again in maybe relatively small numbers due to the actual cost of bringing those skus to consumer. And they are there purely to counter intel’s i3 and i5 non-k offerings.
what you think?
Hardware unboxed has a section in the 5800x review which I very much agree on in terms of the pricing of 5800x.
