AMD announced "Zen 4" with Ryzen 7000 series, RDNA3 teased

By - | Views: 20,644

AMD has revealed their next-generation Zen 4 processors with the Ryzen 7000 series that will be launching September 27.

They're saying it will give a "double-digit" IPC (instructions per cycle/clock) uplift compared to the previous generation. AMD are also claiming they will be a lot more efficient than before, leveraging the power management tech from their mobile processors.

Here's the models they've announced for now:

 Model  Cores/Threads  Boost / Base Frequency  Total Cache  PCIe  TDP Price
 AMD Ryzen 9 7950X  16C/32T  Up to 5.7 / 4.5 GHZ  80MB  Gen 5  170W  $699
 AMD Ryzen 9 7900X  12C/24T  Up to 5.6 / 4.7 GHZ  76MB  Gen 5  170W  $549
 AMD Ryzen 7 7700X  8C/16T  Up to 5.4 / 4.5 GHZ  40MB  Gen 5  105W  $399
 AMD Ryzen 5 7600X  6C/12T  Up to 5.3 / 4.7 GHZ  38MB  Gen 5  105W  $299

This also comes with the new AM5 platform with dual-channel DD5 memory support, up to 24 PCIe 5.0 lanes and they say AM5 will be supported through to 2025. So you're going to be good for the next few generations of AMD processors with AM5. Installation they said will be easier than before with the 1718 pin LGA socket, it supports AM4 coolers too.

These are the chipsets that will be offered:

  • AMD X670 Extreme: Bringing the most connectivity and extreme overclocking capabilities with PCIe 5.0 support for graphics and storage.
  • AMD X670: Supporting enthusiast overclocking with PCIe® 5.0 support for storage and optional graphics support.
  • AMD B650E: Designed for performance users with PCIe® 5.0 storage support and optional graphics support.
  • AMD B650: Designed for mainstream users with support for DDR5 memory and optional PCIe® 5.0 support.

AMD X670 and X670E will be available in September but the B650E and B650 set land in October.

We also got a brief teaser of their next-generation GPUs with RDNA3 as well. During the event AMD CEO Dr. Lisa Su mentioned it uses 5nm chiplets, to provide a "more than 50%" performance per watt uplift compared to RDNA2.

Quoting: BlackBloodRumWill these ones contain the Pluton backdoor?

I can't say for sure, but I haven't seen or heard a single AMD rep state that Ryzen 7000 is infected with Pluton, be it at an event or investor meeting, so I'm hopeful.

Avoiding due to pluton.

I think it's cool, but support until 2025... That seems a little short. Is it?

I mean most won't get these until 2023, and maybe I'm weird, but I don't buy hardware with the intent to replace it in just a few years.

It should mean that they will bring new processors for the platform in 2025 - not that you cannot use your old processor anymore after 2025. I cannot think of a case where I replaced a processor, but not mainboard, RAM, ...

CPUs look promising, but I wonder with 170 W TDP vs current gen 105 W, will high end coolers be able to handle it on full load?

Also, how do you apply thermal paste on that heat spreader plate? I.e. won't it go into those openings?

But do they have Pluton?

Yes I think it is short... but IMHO, I think AMD will extend it beyond 2025, but they dont want to piss off their customers if all of their boards do not support all of the latest features. (Like what happened when some of the AM4 boards did not work at m.2 4.0 speeds) No idea how much further beyond 2025 though..

Something you don't want on your computer, depending on where you sit regarding user freedom.

In simple terms, it's a DRM chip inside the CPU that Microsoft & AMD designed that is similar to those found in the modern Xbox and has the potential to reign complete control over your computer and is cloud connected. For example it can submit documents to the cloud for "attestation" and "verify" that the OS isn't tampered or running pirated software. It can also receive updates from Microsoft via Windows Update and you have absolutely no control over it or say in what it may or may not do. It's great for companies like Epic and their EAC though who wish to have more control over you and your games, it's a wet dream for them.

Sadly, not all details are known about it as Microsoft are keeping their cards close to their chest regarding the full details of how it works.

The more worrying thing isn't so much the potential of "what can it do" but rather why are certain manufacturers, such as Dell & Lenovo rejecting it? They are claiming they will ship it disabled and inactive. So you have to ask yourself why would they, being companies that are fully in the pocket of Microsoft, chose to go against Microsoft like that? What do they know?

Sadly, I am biased against it as I do not support it so I am probably not the best person to explain it. I want gaming to be successful on Linux, but not at the cost of compromising my freedom to use my computer as I wish or to give up my privacy. I simply can't support such a technology.

Probably wait until V-Cache. Also not sold on RDNA3, probably good for pure rasterization work but I suspect no matter how much work they put into RayTracing backend, it never going to work well, especially under Linux.
