If you believe the rumors, then a little more than two months remain before the start of sales of the new Ryzen 3000 processors. Of course, mass production of new products is already underway, because AMD needs to have some stock of new processors before the start of sales. And according to the Bits and Chips resource, the percentage of usable chips for the new AMD Ryzen 3000 series processors is approximately 70%.
In fact, this is a very good indicator for the chips of the new processor, which are also produced on one of the most advanced technical processes. Although it is slightly lower than the output of suitable chips for Ryzen processors of the first two generations. But here the whole point is that the contract manufacturer TSMC, which is responsible for creating crystals for new AMD processors, has relatively recently begun mass production at 7nm standards. And 12- and 14-nm process technologies by the time the Ryzen 1000 and 2000 chips were launched were much better “run-in” and finalized. Over time, the 7-nm process technology will “mature”, and the percentage of product yield on it will increase.
In fact, the high yield of suitable chips for AMD processors is explained by the fact that they have very compact dimensions. Still, the larger the crystal, the more likely it is that any elements on it will be defective, and the crystal cannot be used. This, accordingly, increases the price of finished processors, because all production costs must be returned. For example, 28-core Intel Xeon processors have only a 35% die yield due to their very large size. Therefore, they cost much more than AMD EPYC chips.
AMD processors turn out to be cheaper just due to the use of universal small crystals and their “glues”. AMD will use a similar approach in its future Ryzen 3000, EPYC "Rome" and Ryzen Threadripper 3000 processors. More precisely, they will consist of very small 7nm crystals with computing cores, and a larger 14nm crystal with interfaces input/output.
In the end, we recall that AMD should present its new Ryzen 3000 desktop processors at the end of next month, and they should go on sale closer to mid-summer. Also, EPYC "Rome" server processors are expected to be released by the middle of the year.
