AMD Unveils Zen 2 CPU Architecture, Navi GPU Architecture and a Slew of Products

MojoKid writes: AMD let loose today with a number of high profile launches at the E3 2019 Expo in Los Angeles, CA. The company disclosed its full Zen 2 Ryzen 3000 series microarchitecture, which AMD claims offers an IPC uplift of 15% generation over generation, thanks to better branch prediction, higher integer throughput, and reduced effective latency to memory. Zen 2 also significantly beefs up floating point throughput with double the FP performance of the previous generation. AMD also announced a 16-core/32-thread variant, dubbed Ryzen 3950X, that drops at $750 — a full $950 cheaper than a similar spec 16-core Intel Core i9-9960X. On the graphics side, AMD’s RDNA architecture in Navi will power the company’s new Radeon RX 5700 series, which is said to offer competitive performance to NVIDIA’s GeForce RTX 2070 and 2060 series. The Navi-based GPU at the heart of the upcoming Radeon RX 5700 series is manufactured on TSMC’s 7nm process node and features GDDR6 memory, along with PCI Express 4.0 interface support. Versus AMD’s previous generation GCN (Graphics Core Next) architecture, RDNA delivers more than 50% better performance-per-watt and 25% better overall performance. Greater than 50% of that improvement comes from architecture optimizations according to AMD; the GPU also gets a boost from its 7nm process and frequency gains. Radeon RX 5700 and 5700 XT cards will be available in market on July 7th, along with AMD Ryzen 3000 chips, but pricing hasn’t been established yet for the Radeon GPUs.
