AMD, Vishera, and Beyond: New Design Philosophy Dictates a Faster Pace

by Josh Walrath

Less Risk, Faster Product Development and Introduction

AMD is changing their design philosophy, and Vishera will truly show if they are on the right track or not. The Piledriver cores in Vishera should not only retain the improved power characteristics that were displayed in Trinity, but it should also improve per-clock performance as well as threading efficiency. Details are scarce on what exactly AMD has done to Vishera, but there are plenty of details on what was achieved with Trinity. L2 and L3 cache sizes have not changed as compared to the original Bulldozer, but I would expect a lot of work to be done on the L1 data and instruction caches, the four wide decoders should get a significant boost, and other smaller structures will either be expanded (like the TLBs) or simply improved (pre-fetch and prediction).
