Ryzen Release Thread

AMD's per-core performance, which is generally a mixture of IPC and frequency, has improved substantially with the debut of the Zen 2 microarchitecture, and translates to all types of workloads, be they single- or multi-threaded. As measured with a single-threaded Cinebench workload in the chart above, AMD has made tremendous strides in single-threaded performance compared to the first-gen Ryzen models, with up to 21% more per-core performance with the Ryzen 9 3900X.

AMD has improved memory overclocking substantially, partly due to decoupling the Infinity Fabric from the memory clock. AMD also bumped up the base supported memory frequency from DDR4-2933 to DDR4-3200, but the real advantage comes from heightened memory overclocking potential. AMD's first-gen Ryzen processors had plenty of difficulties with memory overclocking when they first launched, but AMD has addressed those concerns with the second-gen products and even demoed an air-cooled Ryzen platform running at DDR4-5100 at the show.

As with previous-gen Ryzen, memory overclocking confers big performance speedups for gaming. To sidestep the Infinity Fabric's maximum frequency of 2,000 MHz, which effectively constrains memory overclocking, AMD will now allow users to separate the memory and Infinity Fabric clock dependencies. The domains remain tied together at a 1:1 ratio up to DDR4-3733, but run at a 2:1 ratio beyond that transfer rate. This setting, which is user-adjustable in the BIOS, improves memory bandwidth but comes with a latency penalty.

AMD has worked with Microsoft to deliver one a much needed feature: A Ryzen-aware scheduler. The new scheduler arrives with the Windows 10 May update and will benefit both current-gen and previous-gen multi-die Ryzen models (Threadripper and Ryzen 3000 processors).

The new scheduler pins active threads in cores that have localized data, thus improving performance. AMD also introduced its CPPC2 feature, which is a software feature that manipulates Ryzen 3000's power states from within the operating system. AMD says this will reduce power state transition latency from 30ns to 1ns, which will ultimately save power.

AMD CEO Lisa Su recently announced the company's new Ryzen 3000 series lineup at Computex 2019, but left out one official announcement for its Next Horizon Gaming Tech Day here in Los Angeles: The 16-core 32-thread Ryzen 9 3950X for $749. This new processor will land on shelves in September. We have more coverage of the Zen 2 microarchitecture and X570 chipset here.

AMD's 105W TDP rating is also an important consideration. AMD and Intel spec their TDP ratings differently, with the Intel measuring TDP at base clock frequencies, which often leads to an understated number due to much higher power consumption when the processor is in high power states, while AMD uses what is arguably a clearer metric that consists of full utilization of the chip in its dynamic range. In short, this means that the Ryzen 9 3950X should be an incredibly power-efficient chip, so cooling should be a relatively simple task and there should be plenty of headroom for overclocking the soldered chip.
