As always, we suggest taking this information with a pinch of salt as we can't vouch for the accuracy of this leak. If it's correct, pricing of these chips will range from around $316 to $490. As the site noticed, pricing of all three parts is above the Core i5-7600K, and two of them are more expensive than the $330 Core i7-7700K. This should give a rough ballpark of the expected performance of these chips because it implies all three of them may be faster than Intel's fastest Kaby Lake CPUs.
The flagship AMD Ryzen R7-1800X, bearing PIB part number "YD180XBCAEWOF," is priced at USD $490.29. The Ryzen R7-1700X, on the other hand, goes for $381.72. It's interesting to note here that the part numbers end in "WOF," designating "without fan-heatsink."This leak also lends further credence to the rumor that AMD's initial Ryzen launch lineup will consist exclusively of high-end parts. Availability is expected by early March, although some rumors speculate we may see the chips on February 28.
Lastly, there's the Ryzen R7-1700, with 65W TDP, which is priced at $316.59. Given that all three parts are priced above the Core i5-7600K, and two of these are significantly pricier than the Core i7-7700K, which goes for $330, one could read into the chips' possible performance numbers.
