AMD quietly upgrades EPYC 3000 series processors: 8 cores, 16 threads, minimum 25W TDP

Recently, AMD quietly upgraded the EPYC 3000 series embedded processors, adding EPYC 3255 models, 8 cores and 16 threads, TDP minimum 25W, maximum 55W.

AMD launched the EPYC 3000 series of processors in February 2018, which are oriented to the fields of networking, industry, storage, and edge computing. From a blood source point of view, they are the same as the EPYC 7000 series for data centers, with a maximum of 16 cores and 32 threads. , 32MB level 3 cache, SoC system-on-chip design (no additional chipset required), supports up to four channels of DDR4-2666 memory, 64 PCI-E 3.0 buses, 8 10GbE Ethernet, 16 SATA or NVMe devices.

Security is also a top priority. It integrates an independent security subsystem, supports encryption co-processing, hardware root-of-trust, and SME / SEV memory encryption. Of course, enterprise-level RAS features are also required.


The EPYC 3000 series has a maximum of 16 cores and 32 threads, which is powerful enough for the embedded market.

AMD claims that the price/performance ratio of the EPYC 3000 series is up to 2.7 times higher than that of its rival (Xeon D series), and the connectivity is 2 times higher.

Yesterday AMD quietly upgraded the EPYC 3000 series of embedded processors. First of all, two product lines-EPYC 3401 and EYPYC 3301 two 16-core and 12-core processors are no longer provided.

The reason for AMD's deletion of these two processors is unknown. It is very likely that they are too close to the EPYC 3451 and EYC 3351 processors and have no meaning.

While deleting the two products, AMD added a new model- EPYC 3255 processor, 8 cores and 16 threads, TDP 25-55W, frequency 2.5GHz to 3.1GHz, 16MB L3 cache, support 2 channels DDR4-2666 memory, 32 PCIe channels, operating temperature -40 ° C to 105 ° C.

From the perspective of the EPYC 3255 processor, it has significantly reduced TDP power consumption, up to 25W, but the frequency is the same as EPYC 3251, and the working temperature range to which it is adapted has increased significantly. Support low-temperature environment work.

In addition, the distinction between EPYC 3000 series processors is more obvious. The two models of EPYC 3451 and EPYC 3351 use SP4 sockets. These two models have dual-core architectures, while the other CPUs use SP4r2 sockets. Core architecture, memory channels, PCIe and other IO numbers are also cut in half.

In the end the price was still unavailable, it was unclear how much it was. The architecture and process are not mentioned. This should be the same as the EPYC released in 2018. There is no need to toss on the 7nm process.
