AMD on a press conference at Computex 2016 officially presented the 7th generation APUs Codenamed Bristol Ridge and low-end – “Stoney Ridge”. So what can we expect from new APUs?

Well, a new generation of APU is not so new, I can say that it has much in common with the sixth generation Codenamed Carrizo, but the manufacturer has introduced some significant improvements (mainly in terms of power consumption, allowing for even higher performance).

AMD Bristol Ridge and Stoney Ridge – Official Premier Of The Seventh Generation APUs


We still have to deal with up to four cores based on the Excavator architecture and graphics chip based on the Graphics Core Next architecture with up to eight blocks of computing, but the manufacturer has introduced an additional memory controller – next to the 2-channel DDR3 controller, now we have 2-channel DDR4 memory controller. In addition, the system integrates the two bridges, bus controller PCI-Express of 12 signal lines and additional AMD Secure Processor chip responsible for the safety of controller and input / output interfaces.


According to AMD, that in comparison to the 5th generation “Kaveri” APUs launched in 2014, you can expect up to 50% performance increase, but compared to the 6th generation “Carrizo” launched in 2015 the performance increment is only 7%.


Much bigger performance boost for games, for comparing similar models from the generation of Carrizo and Bristol Ridge depending on the title, we can expect a performance increase of up to 28 – 37%.


The new APUs  are characterized by a lower demand for power consumption, which is very important in the case of notebooks, because this will prolong battery life. Presentation of the AMD indicates that the new processors will consume about 9 – 12% less power consumption in comparison with Carrizo.

So how did they do it? Since we are still dealing deal with the same architecture and manufacturing technology. Mainly due to a better power consumption management system, temperature, and operating frequency.

At first AMD improved AVFS technology (Adaptive Voltage and Frequency Scaling), which is responsible for scaling the frequency depending on the voltage of the system. Secondly, they improved STAPM system (Skin Temperature Aware Power Management), and thus the ability to speed up the system, when it does not exceed the set limit temperature and at third they improved BTC technology (Boot Time Power Supply Calibration), and so the use of higher voltages for different energy states.


So it comes out that, AMD preferred to squeeze the last juices out of an old architecture than to introduce a completely new design. How do they manage the new systems? We will find out soon, because some manufacturers have already prepared the device with new APUs – in the beginning, we will see the new APUs debut on ultra-thin laptops and convertible PCs All-in-One.
