New rumors have emerged regarding the possible launch of AMD's new Radeon RX `RDNA 3` GPU and Ryzen` Zen 4` Raphael CPU series, scheduled for Q4 2022. Twitter user Vegeta exposed these rumors: Someone has leaked fairly accurate reports in the past (discussing potential specs, performance benchmarks, and release schedules for various next-gen hardware products).

In his recent post, Vegeta suggested that these two new technologies will be available at the same time, which is expected in the fourth quarter of 2022. With AMD officially announcing the launch of Zen 3 / RDNA 2 in the fourth quarter of 2020, this seems to be quite popular, which means there will be 2 years between the two architectures.

Although two years is a long time, AMD fans don't have to worry too much: the red team is hoping to launch some products between Zen 3 and Zen 4 (most notably the Ryzen 5000XT CPU and the recently announced Zen 3 processors with 3D VCache technology) . RDNA 2 and 3 are the same, some high-performance products are expected to fill the generation gap. Vegeta goes on to state that AMD hopes to release its first RDNA 3-based Navi 3X GPU later this year, becoming the successor to the current Navi 2X GPU that is now available in the RX 6000 series GPU lineup.

All of this It happened when AMD started to turn things around in their favor in the Red-Blue War, and there was more buzz around this brand that can't go wrong now. That said, we are still over a year away from the advent of new technology, so don't go too far now.

First of all, as you may have noticed, the new Zen 4-based Ryzen desktop CPU series will be codenamed Raphael and will replace the Zen 3-based Ryzen 5000 series CPU series, codenamed Vermeer. . Judging from the small amount of information we currently have, we can expect that the Raphael CPU series will be based on the 5nm Zen 4 core architecture, using 6nm I / O chips in the small chip design.

Recently, AMD has often hinted that it will increase the number of cores in its next-gen consumer CPU product line, so don't be surprised to see an increase in the number of cores compared to the current flagship product with 16 cores / 32 threads. .

When it comes to performance, users should expect IPC gains of up to 25% over Zen 3's alternative clock speeds of up to 5 GHz, respectively.

In a statement to Anandtech by AMD CEO Dr. Lisa Su:

"Mark, Mike and the team have done an extraordinary job. Our products today are as good as we are, but according to our ambitious worksheet. route, we are focused on Zen 4 and Zen 5 to improve competitiveness. "" There will be more core counts in the future, I will not say they are limitations! As we expand the rest of the system, it will appear. "

AMD I hope to make the new technology backward compatible. However, at this early stage, we do not know whether "Zen 4" will be backward compatible. However, what we do know is that the new LGA1718 will support AM4 CPU, and the motherboard will replace the current AM4, thereby reducing the possibility of backward compatibility. In other words, when the AM5 arrives, we can expect to see the rig in use for at least a few years, making any new construction using it very future-proof.

It is said that the new platform has DDR55200MHz memory, 28 PCIe Gen 4.0 channels and a large number of NVMe 4.0 / USB 3.2 I/O, not to mention the potential native USB 4.0 support. Rumors also indicate that CPUs up to 170W will be compatible with the AM5 platform. In addition, Raphael Ryzen desktop CPUs are also expected to be equipped with RDNA 2 integrated graphics, which means that unlike the Ryzen 5000 series, AMD’s new mainstream CPU product line will also support iGPU, such as Intel desktop CPUs.

As mentioned earlier, we expect the Radeon RX 7000 series "RDNA 3" series to be launched at the same time as the "Zen 4" in the fourth quarter of 2022. The new RX 7000 series graphics cards will use Navi 3X GPUs, and three main chips have been leaked. Navi 31, Navi 32 and Navi 33 are three main chips.

Like "Zen 4", the "RDNA 3" line is expected to use TSMC's 5nm process node and the same packaging technology, such as small chip (MSM)-we have seen it in Ryzen desktop CPUs. While bragging about its GPU victory, AMD did not remain silent. David Wang and his team at RTG often discuss how they bring RDNA 2 to life, many of which are the same concepts used in the design of the third-generation RDNA architecture.

Recent rumors about the new RDNA 3 GPU indicate that the flagship Navi 31 GPU will be equipped with 160 computing units and more than 10,000 cores, and its performance will be 3 times higher than that of the Big Navi 21 GPU. There are also rumors about the performance of

-specification Navi 33 GPUs. They provide 80 computing units, 5120

cores and higher performance than the current Radeon RX 6900XT. In addition, AMD has obtained a patent for an active bridge chiplet solution for next-generation GPUs, which will provide integrated cache and interconnect multiple arrays on Navi 3X (RDNA 3) GPUs.

As always, AMD RDNA 3 `Navi 3` series GPUs will compete with Nvidia's own MCM GPU based on Ada Lovelace GPU. Although the part is scheduled to be launched at the end of 2022, the hardware issues we currently see may set it back further, so don’t be dazzled now.
