AMD Announces DDR4 RAM Is Dead

This Monday (30), My God Announced its line of processors Ryzen 7000With the first models aimed at desktop computers, it will compete for market with Intel’s rival Alder Lake line. To this end, the company has embraced future-ready designs by prioritizing the latest standards.

Although the first models of compatible motherboards supported PCIe 4.0, the idea is, over time, to abandon it in favor of 5.0; Already with RAM, AMD was not so good: the Ryzen 7000 line does not support DDR4Just DDR5Unlike Alder Lake who works with both.

AMD has been very clear when giving their reasons, and DDR4 has already given what it has to offer, it’s an old and outdated standard. It’s time to put an end to it, as much as the public doesn’t like it, and there’s a reason for that.

For AMD, DDR4 has reached its limit

Centered on the theme “Advancing Technology in Computer Hardware,” AMD’s presentation provided solutions and components that enable assembly and maintenance of clusters. future proof. The idea, repeated throughout the broadcast, is “whatever you ride today, it will remain usable tomorrow (in the long run)”.

In a brief and straightforward presentation, CEO Dr. Lisa Su has detailed a roadmap for the next few years, in which TSMC’s 5nm architecture, used today with Ryzen 7000 chips, which uses an AM5 socket, will gradually evolve to 4nm, and arrive in 2024 at 3nm, with the Zen 5c line. But let’s focus on now.

Mark Papermaster, AMD’s chief of staff and executive vice president, was responsible for providing details about the new processors. In the end, he clarified that the PCI Express 4.0 standard, which began to appear on the market in 2019, will be gradually replaced by PCIe 5.0, so future models and processors will gradually support the second standard.

The same cannot be said of RAM, as the paging process will be even more traumatic, so to speak. David McAfee, Corporate Vice President and Head of Desktop Division, explained that unlike what Intel did with Alder Lake, AMD has completely abandoned DDR4. Anyone who wants to build a PC with the company’s new processors will have to rely on DDR5.

McAfee explained that the AM5 is designed to take full advantage of the latest components, as AMD is apparently aiming for Ryzen 7000 processors, the latest Radeon GPUs and, in the case of RAM, only DDR5.

The company’s argument makes sense. Officially introduced in 2013, DDR4 has been the industry standard for desktop computers, laptops, video game consoles, and mobile devices since 2014. Today, the company considers that we’re on the cusp of a new technology leap, and more powerful and faster components are needed to handle New solutions, such as 5G, for example.

The DDR4 standard works with normal frequencies between 1600 and 3200 MHz, although it supports a speed limit of 4800 MHz, which is the starting point for DDR5 memory. That’s right, the fastest frequency of the current flagship RAM format is the slowest that its successor can offer, according to the specifications, it can reach 9600MHz.

DDR4 vs DDR5: The Differences

DDR5 incorporates many improvements over DDR4. Speaking of the highest frequency, the market standard should be 6400MHz, which provides a faster access to information.

The maximum SDRAM density has increased 4 times, supporting up to 64GB per chip; Thus, the size of a single stick can range from 32 GB to 128 GB, while the length of the burst is doubled, from 8 to 16 bits; The memory channels also changed, becoming two 32-bit, instead of 64-bit as in DDR4.

Power efficiency has also been improved, with the standard voltage of 1.2V reduced to 1.1V, and the maximum voltage reduced from 2.5V to 1.8V. Improve and simplify their designs, especially since DDR5 will have a voltage regulator built into the comb, eliminating its inclusion on the motherboard.

This is designed to benefit manufacturers and OEMs, who would be free to offer simpler and cheaper products; On the other hand, the inclusion of the direct regulator in the comb weighed for the end consumer, the price of the DDR5 comb is much higher than that of DDR4.

AMD will force the death of DDR4

AMD is clearly looking to the future, and wants to offer more powerful products than Intel, which by maintaining compatibility with DDR4, is forced to settle its chips from the bottom. The big problem is that DDR5 sticks are still very expensive and hard to find, and manufacturers prefer to stick with the old standard, because it’s cheaper.

However, said Dr. Lisa Su is simple: By adopting more modern designs, the Ryzen 7000 line promises to deliver more performance than Alder Lake, whose solutions will be preferred among consumers who value power first, such as Glorious PC Gamer Master Race. Su emphasized that its platform, today (Ryzen 7000 + Radeon GPUs + PCIe 5.0 + DDR5), is the best for PC gaming with maximum graphics quality.

If Intel feels uncomfortable in a possible future scenario, with AMD increasing its presence among the public and hurting its sales, it could review Alder Lake and release new chips that only work with DDR5, where the entire parallel industry, from consoles to the mobile market, will follow. And the gradual transition from DDR4 to DDR5 means that over time, modern sticks will become cheaper and more expensive.

Somehow, it’s time to move on to the next generation of RAM. Someone needs to take the first step, even though the AMD strategy is painful (expensive) at first. But as they say, you can’t make an omelette without cracking some eggs.
