AMD is refreshing it’s mobile processor lineup with the launch of new chips including high-power models aimed at high-performance gaming laptops and mobile workstations and more energy-efficient chips designed for thin and light laptops.

All of the new additions to the AMD Ryzen H-Series line of high performance Ryzen 6000 series processors, which are 6nm chips featuring new Zen 3+ CPU cores and RDNA 2 integrated graphics. New U-Series chips are a bit more of a mixed bag, with some models featuring the latest technologies while others are more modest updates to last year’s 7nm Ryzen 5000U chips with Zen 3 CPU cores and Vega graphics.

The big news is that AMD says its Ryzen 6000 mobile chips bring up to 1.3X more processing speed and up to 2X the graphics performance of their Ryzen 5000 counterparts. But these are also energy-efficient mobile chips designed to offer long battery life when you’re not pushing the chips to their limits by playing games, editing videos, or running other resource-intensive tasks. AMD says you can expect up to 24 hours of battery life for video playback on a laptop with a Ryzen 6000 processor.

The new chips are also the first processors to incorporate Microsoft’s new Pluton security processor, and while they still don’t have native support for Thunderbolt, AMD says the Ryzen 6000 platform includes support for USB4 40 Gbps ports, PCIe Gen 4, DDR5 and LPDDR5 memory, WiFi 6E and Bluetooth 5.2, and HDMI 2.1 and DisplayPort 2.

And the new RDNA 2 graphics technology makes the Ryzen 6000 series chips the first integrated GPUs to support hardware-accelerated ray tracing. AMD says the GPU Compute Engine is 50% larger and the new GPU supports frequencies up to 2.4 GHz.

Here’s a run-down of the first Ryzen 6000 H-Series processors:

  1. No one knows what Pluton actually does, but it’s being speculated that this is the end of privacy and freedom on personal computers.
    Some predictions I’ve heard are:
    “any server can ask for your cpu’s hard coded, immutable encryption keys and your computer won’t be able to refuse, making you uniquely identifiable no matter what you try and do”
    “software you download and run will be encrypted with your keys which you can’t extract and drm will effectively be uncrackable”
    “your computer will not boot unless it can contact Microsoft’s servers, and even if it can, a bunch of stuff won’t work”
    “you can forget about being able to install any alternative operating system you want ever again, pick from 2 or 3 arbitrarily supported distros, loser.”
    Not every server, software, or service will rely on remote attestation, but things can slowly roll out through updates until almost everything does. Your computer being uniquely identifiable permanently is a dream for forum moderators. It’s a dream come true for DRM. And it’s a dream come true for authoritarian governments everywhere.

    1. Oh, and a big prediction I forgot to mention: “if some law enforcement agency gets a warrant for your computer, they can now have Microsoft install a firmware backdoor on your machine, so they’ll get you even if you don’t have a Microsoft account, unless you installed another OS before you became a person of interest”.
      And another, which is the only one of my own, “C2PA will use the TPM (Pluton or otherwise) to automatically sign any images you upload to any website with your computer’s keys”.

  2. I’m also slightly confused what the exact differences are between usb4 and thunderbolt 3. As far as I understand, the bandwidth should be the same, so the main thing preventing graphics docks from supporting USB 4 might be some specifics of the thunderbolt protocol, but not the lack of bandwidth, right? (at least not more than bandwidth is limited in tb3)

      1. This is not entirely true for Ryzen 6000. A better way to explain this is official USB 4.0 certification is not required to have Thunderbolt support. Since it also targets devices such as smartphones and low-end tablets where Thunderbolt simply doesn’t make sense, they make it optional for manufacturers to roll in Thunderbolt features in order to be USB 4.0 certified. That said, I can confirm from what AnandTech and XDA Developers have said that AMD’s Ryzen 6000 implementation of USB 4.0 on its processor does indeed include Thunderbolt support. Because of this smart design move by AMD, it is just as easy now manufacturers to add Thunderbolt to AMD as Intel without the elaborate, additional BOM cost of an outboard Thunderbolt chip as in the past. Manufacturers who use Ryzen 6000 only need to route in the necessary traces and very minimal supporting signal electronics (just as on Intel devices) to have Thunderbolt on their Ryzen 6000 devices’ USB 4.0 ports.

      2. The tell-all that it includes Thunderbolt on-die in the USB 4.0 implementation is the mention of 40gbps that AMD has stated in the press briefings. That is why AMD users are very excited. A theoretical Steam Deck 2, for example, would benefit tremendously from this feature for those who want to up their graphics performance at home with an eGPU.

  3. It’s really unfortunate that they’re still not offering native Thunderbolt support.

    I’m not exactly 100% up to speed on the AMD/Thunderbolt situation. I know at this point, the standard is now royalty-free, and it’s free to implement on AMD motherboards. But I’m not sure what is preventing AMD from implementing it in their CPUs.

    1. This is incorrect. Native Thunderbolt is included in AMD’s on-die implementation of the USB 4.0 specification. What Brad shared is true but that is more applicable to, for example, smartphone manufacturers who want to slap on a fancy USB 4.0 sticker on their product box. Thunderbolt is optional in that case, which makes sense given the lack of need of Thunderbolt on a smartphone or a lower cost device with a low-end processor. To the contrary, AMD has opted to bake in the Thunderbolt parts of USB 4.0 into their USB 4.0 implementation on their Ryzen 6000 processor floorplan. So if a PC maker wants to have Thunderbolt on Ryzen 6000 device, it is just as easy for them now as a current generation Intel device. Before this, they had to add an external chip which added cost, complexity and power requirements that made it very undesirable. No longer.
