AMD launches Ryzen 9000 desktop processors based on the Zen 5 architecture – Computer – News

AMD has announced its Ryzen 9000 series desktop processors. These processors are based on the all-new Zen 5 architecture and are built on TSMC’s 4nm process. The processors will be available in July. Recommended retail prices are not yet known.

As in previous years, AMD is initially offering four processors in its desktop Ryzen 9000 series. The Ryzen 9 9950X will be the top model in the lineup. This again has 16 cores and 32 threads, with boost clocks up to 5.7GHz. Additionally, this processor has a total L2 and L3 cache of 80MB, and a TDP of 170W.

Below the Ryzen 9 9950X, the Ryzen 9 9900X, Ryzen 7 9700X, and Ryzen 5 9600X CPUs will be available. They have 12, 8 and 6 cores respectively. AMD has not changed the number of cores compared to the previous few generations, although according to AMD, the performance of the new cores should be much better than the previous generation.

In productivity benchmarks published by AMD, the top-of-the-line Ryzen 9 9950X performs up to 56 percent better than the Intel Core i9-14900K, depending on the exact workload. In games, these percentages range from 4 to 23 percent, depending on the game. There are no independent standards available yet.

In many cases, TDPs have also been reduced compared to previous models. The top 16-core model maintains a TDP of 170W. However, the 12-core Ryzen 9 9900X has a TDP of 120W, while it was previously 170W. Both the Ryzen 7 and Ryzen 5 versions have a 65W TDP; With their Zen 4 counterparts it was still 105 watts. The chips will be available sometime in July, but a specific date has not been set yet.

The Zen 5 architecture delivers a 16 percent higher IPC rate

All the mentioned processors are based on the new Zen 5 cores. These offer average, according to AMD ipc-Up to 16 percent improvement over Zen 4. This means that Zen 5 chips should be on average 16 percent faster at the same clock speeds and the same number of cores, depending on the workload.

While AMD sometimes offers relatively minor updates between two generations of Zen hardware, the company claims that Zen 5 is a more fundamental upgrade compared to Zen 4. The manufacturer has made several changes. For example, accuracy and latency Branch prediction An improvement over Zen 4. The company is also talking about a higher level Productivity This is thanks to wider pipelines and tankers, as well as larger lines Window sizesso the cores can better work in parallel.

With all this, the chipmaker claims that Zen 5 has 1-2 times more bandwidth for front-end instructions. This also applies to the data bandwidth between the L2 and L1 cache, and from L1 to the FP. In addition, the “AI” performance should be twice as high as in the Ryzen 7000 series. The desktop chips do not have an NPU for AI computing tasks, unlike AMD’s new Ryzen AI laptop processors.

Furthermore, the Zen 5 architecture once again supports DDR5 memory. The chips also offer PCIe 5.0 lanes again, though the manufacturer didn’t say how many lanes the CPUs will have. Current Ryzen 7000 CPUs based on Zen 4 have 28 PCIe 5.0 lanes, of which 16 are dedicated to the video card and 8 to SSDs. The remaining four PCIe 5.0 lanes are used to communicate with the chipset.

Platform: AM5 again, but new X870 chipset

The CPUs once again use the AM5 platform, which was introduced with the previous Ryzen 7000 series. According to AMD, users can expect new AM5 processors after 2027. AMD, along with the new Ryzen 9000 chipsets, is introducing the new high-end X870 and X870E chipsets with several improvements over the X670(E).

According to AMD, all X870 and X870E motherboards will support USB4 as standard. It also ensures that all motherboards with this chipset support PCIe 5.0 for the GPU and SSDs. Additionally, the new chipsets should support higher memory speeds via EXPO overclocking profiles.

AMD didn’t show any physical X870 and X870E motherboards during its presentation. The manufacturers will likely announce this themselves in the coming days during the Computex 2024 trade show in Taiwan. The motherboards are expected to be available in July, along with the Ryzen 9000 chipset.

The AM4 gets two new Ryzen 5000 CPUs

AMD is also introducing two new Ryzen 5000 processors, which will be available on the AM4 platform that debuted in 2017. These will once again be based on the Zen 3 architecture, but will offer higher clock speeds than before. For example, the Ryzen 9 5900XT has sixteen cores with a boost clock of up to 4.8 GHz. The Ryzen 7 5800XT has eight cores with the same boost speeds.

AMD says the new Ryzen 5000XT processors will be available in July, but did not mention prices. The chipset comes with a Wraith Prism cooler.
