At its official CES briefing, AMD CEO Dr. Lisa Su revealed the 3rd-gen Ryzen processors, Radeon VII graphics card, and a new Epyc enterprise processor.

3rd-gen AMD Ryzen HEDT processors

AMD unveiled an 8-core, 16-thread 3rd-gen Ryzen high-end desktop (HEDT) processor at its press conference today. The processor is built on AMD’s new Zen 2 architecture based on the 7nm transistor node.

Besides cementing the manufacturing process, core count, and the architecture, Dr. Su kept most other specifications under wraps, stressing that the demos are running on early chip samples. While most of its details remain nebulous, we do know that the 3rd-gen HEDT Ryzen uses a two-die chiplet design, with one die dedicated to input-output and the other to compute.

What’s intriguing is that the IO die is made from 14nm transistors, while the compute die is made from 7nm. This explains why the two dies are separate.

On stage, the 3rd-gen Ryzen chip edged out a stock 8-core, 16-thread Intel Core i9-9900K with a scored 2,157 versus the Intel’s 2,040. In addition, it drew 46W less power – an expected result considering that the Ryzen uses the newer 7nm transistor process.

Dr. Su also mentioned that the 3rd-gen Ryzens will feature native support for PCIe 4.0 which features twice the bandwidth of PCIe 3.0.

The new processors will use the existing AM4 socket and will be backward-compatible with current-gen AMD motherboard chipsets.

AMD’s 3rd-gen Ryzen processors are expected to land in mid-2019. There’s currently no official pricing announcement.

AMD Epyc

Alongside the 3rd-gen Ryzen processors, the 2nd gen Epyc server processors. The 64-core, 128-thread flagship chip is also based on the Zen 2 architecture. AMD pitted the chip against two Intel Xeon Platinum 8180 in a HDL protein folding simulation and showed that its single chip was 15 per cent faster.

The Epyc chip is expected to ship mid-2019.

AMD Radeon VII

AMD also announced the Radeon VII graphics card featuring 2nd-gen Vega architecture, 60 Compute Units (60 CU), 1.7 GHz core clock, and a whopping 16GB of High-Bandwidth memory. Interestingly, Lisa Su said the Radeon VII has the same power envelope as the 1st-gen Vegas, which means it will draw more power than the Nvidia RTX 2080.

All the technical jargons translate to about 29 per cent performance increase in all workloads over first-generation Vega and similar performance to the Nvidia RTX 2080.

The reference Radeon VII card featured metallic shroud and triple fans.

The AMD Radeon VII graphics card will go on sale on Feb. 7 for $699, undercutting the Nvidia RTX 2080’s launch price by $100 but overshoots the AMD Vega 64’s launch price by $200. The cost increase could be partially explained by the newer manufacturing process and the increased HBM buffer size.
