Hi, Radeon fans! Over the past few months you’ve undoubtedly learned quite a lot about the Polaris architecture, but we also know many of you have a boundless appetite for deeper technical detail. If you’re one of those PC enthusiasts, today’s updates will be pretty interesting for you!
First, we’re officially publishing the Polaris architecture whitepaper. This is our bible for everything that’s new, interesting, or different in the 4th-gen Graphics Core Next ISA and all the partner silicon—like media encoding or display controllers—in the Radeon™ RX 400 Series GPUs. Here’s an excerpt to whet your appetite:
Every flip-flop has a clock input, data input, data storage, and data output. The clock input triggers the flip-flop to transit its stored data to the output and receive new data from the input. A clock network runs throughout the entire chip, distributing clock signals that synchronize operation. In active operation, the clock network typically consumes around 20-35% of the total power of a Polaris-based graphics chip.
Next, we’ve heard from many on Reddit and Twitter that you are interested in obtaining a copy of the presentation we developed to explain the various features and benefits of the Polaris architecture. We’re making that available today as well.
As an example, this presentation can help you learn more about a technology we call adaptive clocking. Adaptive clocking is an AMD-built power efficiency booster that allows for higher out-of-the-box clockspeeds via nanosecond-fast compensation for transient voltage drops that accompany changes in shader workloads. There are many more technologies besides, so this presentation will certainly make for some fascinating reading for those of you that want to know more about how Radeon GPUs are built.
