AMD demonstrates an unreleased 5.5GHz Ryzen 7000 CPU crushing Intel’s Core i9 12900K

AMD has finally taken off its next-gen Zen 4 processors and the gloves against the Intel Alder Lake architecture. Dr. Lisa Su took the stage for the now-traditional AMD CEO keynote for Computex 2022, and showed off a pre-production 16-core, 32-thread Ryzen 7000 processor beating a 16-core, 24-thread Intel Core i9 12900K in the popular Blender rendering software.

The engineering sample completed the rendering test nearly a third faster than the competing Intel processor of its last generation.

Promising over 15% single-threaded performance boost – compared to its last generation Ryzen 9 5950X— this entire new generation of processors is AMD’s latest bid to dominate not only the direct computing market, but the gaming world as well.

Not only did we see the rendering demo on stage this year, but Dr. Su also showed us the same 16-core Zen 4 chip running through Ghostwire Tokyo with its core frequency hitting between 5.3GHz and 5.5GHz.

“We designed Zen 4 to run significantly faster than our previous generation,” says Dr. Su, “and that increase in frequency can translate to a smoother gaming experience. And while this is just one example, we’re really excited to have gamers get their hands on our Ryzen 7000 series.”

This is reiterated in our pre-briefing with Robert Hallock, Director of Marketing for Ryzen CPUs, where he explains that over 15% increase in single-threaded performance – one of the things that will really help when it comes to gaming – “lifts everyone boats.”

“This is an important focus for us, which will be a combination of CPI and frequency, and we will provide the breakdown later in the year.”

All Ryzen 7000 series chips will have a certain amount of graphics built in.

Basically, part of this performance boost is due to the extra clock speed that AMD extracted from the optimized TSMC 5nm process, as well as the raw instructions per clock (IPC) increases born from the new Zen 4 CPU architecture. greater impact, we won’t know until closer to launch.

You’ll also get double the L2 cache of the Zen 3, with 1MB per core being offered across the entire range, which will probably help a little with the higher performance too, huh? Just keep throwing more cache on things, that’s modern computing. It works.

As with the Zen 3 and Ryzen 5000, the new Ryzen 7000 processors will have a maximum of two Core Complex Dies (CCDs), each with eight Zen 4 cores. This means, once again, that we will see 16 cores as the top of the tree. technology in this Ryzen generation.

But while the 5nm core chiplet may look all too familiar, Hallock tells us that “it’s actually the I/O array that sees the biggest change.”

That’s because the 6nm I/O array is where the new RDNA 2 integrated graphics chip lives. This is a first for AMD because while it has long had its APUs offering iGPUs, most of its processors were shipped without any graphical resources. It’s fine if you always have a discrete graphics card on hand, but for enterprise customers, and just trying to boot a rig when your GPU is broken, not having a backup can be a pain.

A pain no more, however, as Hallock states that “all Ryzen 7000 series chips will have a certain amount of graphics built in”.

In addition to the GPU, the I/O array is also where the DDR5 memory controller and the controller for the PCIe 5.0 interconnect also live. There’s also a new low-power on-chip architecture that pulls a bunch of technology from current Ryzen 6000 series laptop processors to help with desktop efficiency.

Where the interior has something familiar, the exterior is a complete departure from old AMD chips. Gone is the boring square heatsink, and comes a funky cutout design and LGA socket connection.

We’ve been told by AMD’s David McAfee that part of the reason for switching from the old PGA design, pinned chips, to the LGA configuration is “to generate more power and greater signal integrity for all that speed I/O.” With DDR5 and PCIe 5.0, there’s a lot of throughput to deal with, after all.

This heatsink design isn’t just about aesthetics, it’s about platform compatibility. Of course, these new AM5 processors won’t fit in an old AM4 socket, but the design is such that they are still compatible with the AM4 CPU cooler ecosystem.

It’s a “very unique design,” says Hallock, “that helps us keep the cooler compatible with the AM4 socket. There’s a real method to the design here; it allowed us to keep the same package size, the same cooler protection. .”

The processor itself is a very important part of the equation, but it’s nothing without a capable motherboard platform to build on. And here’s a whole new world as we bid farewell to the AM4 platform, the socket that launched 125 unique chips and sold nearly 70 million CPUs.

The new AM5 platform will consist of three separate chipsets: X670 Extreme (or X670E), X670 and B650. All three have the same 1718-pin LGA AM5 socket, but come with different levels of support for the new technologies on offer.

It’s worth noting that while the B650 is the lowest cost option for your Zen 4 PC builds, you’ll still need expensive DDR5 memory to run it as there’s no option on any of the chipsets to have DDR4 support. . it’s on the CPU.

“We’re not supporting DDR4,” says Hallock, “this is an exclusively DDR5 platform. We’re super excited about what DDR5 can deliver, both from a performance and a power standpoint.”

This might make it difficult to build a truly affordable Ryzen 7000 machine in the short term, but DDR5 prices will inevitably come down, and this is a platform destined to be around for many years to come.

We still don’t have an exact release date for the new Ryzen 7000 series running on the Zen 4 architecture, or the cards they will live on. . But when they do, it will truly be a new dawn for AMD’s processor division in many ways.
