Amd rumours of rdna 3 and zen 4 cpu gpu leaked

There are new rumors surrounding the possible launch of AMD’s new Radeon RX `RDNA 3` GPU and Ryzen` Zen 4` Raphael CPU series, which are scheduled to be released in the fourth quarter of 2022. These rumors were exposed by users. From Twitter Vegeta, someone leaked fairly accurate reports in the past (discussing potential specifications, performance benchmarks, and release schedules for various next-generation hardware products).

In his recent post, Vegeta suggested that these two new technologies will be available at the same time, and the expected arrival date is the fourth quarter of 2022. With the release of AMD Zen 3 / RDNA 2, this seems very popular. The product was officially announced in the fourth quarter of 2020, which means there will be 2 years between the two architectures.

Although two years are long, AMD fans don’t have to worry too much. The red team hopes to launch a series of products between Zen 3 and Zen 4 (most notably Ryzen 5000XT CPU and the recent 3D release Zen 3 processor with VCache technology). The same can be said for RDNA 2 and 3, some high-performance products are expected to fill the generation gap. Vegeta continues to state that AMD is expected to write its first RDNA 3-based Navi 3X GPU later this year, becoming the successor to the existing Navi 2X GPU in the RX 6000 series GPU lineup.

All this happened when AMD began to reverse the situation in the battle between red and blue, generating more buzz around this brand, and now you can't go wrong. Having said that, we are still more than a year away from the arrival of new technologies, so let's not get overwhelmed.

First of all, as you may have noticed, the new Zen 4-based Ryzen desktop CPU series will be code-named Raphael and will replace the Zen 3-based Ryzen 5000 series CPU series named after the Vermeer code. Judging from the small amount of information we currently have, we can expect that the Raphael CPU series will be based on the Zen 4 5nm 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. .

In terms of 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 in line with our ambitious sheet. en 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 series will also support iGPU, such as Intel desktop CPUs.

As mentioned above, we expect the Radeon RX 7000 series "RDNA 3" series to be launched at the same time as "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. The three main chips in Navi 31, Navi 32 and Navi 33.

Like "Zen 4", "RDNA 3" line is expected to use TSMC 5nm process node, and the same packaging technology, such as small chip (MSM)-we have seen in Ryzen desktop CPU. 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, and use many of the same concepts when designing 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 compute units, more than 10,000 cores, and its performance will be 3 times that of the Big Navi 21 GPU. Navi 33 GPU

performance specifications can provide 80 compute units, 5120

cores and higher performance than the current Radeon RX 6900XT. Additionally, AMD has applied for a patent for a next-generation GPU active bridge chiplet solution, which will provide an integrated cache and interconnect multiple chips in the Navi 3X (RDNA 3) GPU.

As always, the AMD RDNA 3 `Navi 3` line of GPUs will compete with Nvidia's own MCM GPU based on the Ada Lovelace GPU. Although the parts are scheduled to be produced in late 2022, the hardware issues we are currently seeing may further delay the process, so don't feel too complacent for now.
