Zen3 + at 6nm with RDNA2 graphics


The notebook market is a tough nut to crack. People want that mix of high performance at the top, cost-effectiveness at the bottom, and there has to be efficiency, utility and function everywhere. After successful growth last year, AMD is once again stunning the notebook market in 2022 with the launch of its new Ryzen 6000 Mobile processors. These ‘Rembrandt’ APUs feature AMD’s latest RDNA2 graphics, up to eight Zen3 + cores with enhanced power management features and use TSMC’s N6 manufacturing process to improve performance and efficiency.

It’s all in Silicon: Rembrandt is a code name

Yesterday AMD announced that today it will launch the new Ryzen 6000 Mobile series – updated core, better graphics, more functions, all in one monolithic package of just over 200 mm2. There will be 10 new processors, ranging from traditional 15W and 28W portable hardware, to 35W and 45W plus for high-end gaming machines. AMD expects 200+ premium systems on the market with Ryzen Mobile in 2022.

At the heart of the design is AMD’s Zen 3+ core, which allows for improved power management between cores, but retains the characteristics of Zen 3 performance. The focus here is mainly on improving standby power consumption and accelerator power, to extend the life of ultraportable devices – AMD claims 15-40% lower power consumption between web browsing and video streaming. There is also an increase in frequency, with high-end processors going up to 5.0 GHz. AMD claims to have up to 1.3x multi-thread performance for the Ryzen 7 6800U.

This is connected to 12 computer units of the RDNA2 graphics engine, upgraded with eight Vega units. This is the broadest integrated graphics engine AMD has ever made, with a 50% increase in units, but also a fundamental change in GPU design – double graphics cache, double rasterization performance, double rendering background and hardware-accelerated air tracking. The frequency is also increased by + 20% from 2.0 GHz to 2.4 GHz. In gaming performance at 15W at 5800U versus 28W at 6800U, AMD claims a 1.8-2.0x jump over the previous generation *, and anywhere from 1.2x to 3.0x at 1080p over the competition . If we add FidelityFX Super Resolution, AMD proposes another + 20-60% in the number of frames. This, combined with memory improvements, should be good for integrated gaming. GPU rendering performance according to AMD is up to 2.3x faster generation, but it should be noted that the GPU supports AV1 decoding, both 8-bit and 10-bit streams.

* It should be noted that AMD tested the 6800U at 28W of nominal TDP, not 15W
** We originally stated that Rembrandt does not support AV1 based on our interpretation of one of AMD’s slides – since then we have confirmed that the chips support AV1 decoding, both 8-bit and 10-bit, supported by AMD’s VCN IP inside the chip .

When paired with AMD’s new mobile graphics solutions, Rembrandt’s 35W + series may feature AMD’s Advantage platform. The idea is that with the A + A design, the system can use SmartShift Max which allows dynamic power adjustment between the CPU and the discrete GPU, leading to higher performance. This can also be used to extend battery life or in combination with AMD SmartAccess graphics, it can be used to ensure the best GPU is used at all times.

The new Rembrandt CPUs will also have updated memory controllers, with support for up to DDR5-5200 and LPDDR5-6400 – it is worth noting that there is no support for DDR4 here, which makes a clean cut to DDR5 standards. (Ian: that could mean an increase in costs during the first few months of these products.) AMD has also increased from PCIe 3.0 to PCIe 4.0, supporting 8x for discrete GPUs and 12x split between NVMe, SATA and chipset. There’s also native support for USB4, which allows vendors to monitor Thunderbolt 3 specifications if needed.

In terms of accelerators and security, Rembrandt has support for Microsoft Pluto, which has been in preparation for several years as a way to provide connected security between the system, OS and potentially the cloud. Features such as user memory protection are welcome, however there have been concerns that Pluto opens more doors than it closes, depending on your jurisdiction. To put it mildly, according to the details in the firmware and open source drivers, Rembrandt will also include computer-based machine learning hardware – a pair of Tensilica Vision Q6 and C5 DSPs, which should offer more functionality around laptop cameras when put together. use. These types of mobile APUs also end up in embedded systems, such as augmented reality or automotive, which could expand the offering there.

In this announcement, it is interesting to see that most of the comparison numbers that AMD has supplied us are for 15W hardware, however 80% of CPUs launched today are more focused on 35W and more space. It will be interesting to see how 35W + will work in comparison, given that at 35W + we expect to see most systems with discrete GPUs, and most of the Rembrandt improvements were in integrated graphics. However, we will see many systems using Ryzen 6000 Mobile that were announced this week – AMD states that some of them should start selling around February.
