While Intel's Developer Forum is underway in San Francisco, not far from AMD in Sunnyvale, the x64 creators held a press conference to demonstrate Zen CPU performance. Based strictly on the presentation, AMD shows a 40% IPC (Instructions Per Clock) over Vishera. The demonstration used a 16T processor, the “Summit Ridge” chip that's been discussed a few times, which runs 8 cores with simultaneous multi-threading (SMT) for 16 total threads. For the non-gaming market, CPU codename “Naples” was also present, a 32C/64T Zen server processor in a dual-CPU Windows server.
AMD detailed more of the Zen architecture in an official capacity, commenting on new caching routines and branch prediction, accompanied by the SMT changes that shift AMD away from its modular Bulldozer architecture. AMD made mention of “fanless 2-in-1s” in addition to high-performance CPUs and embedded systems.
In a recent story circulating the web, rumors of AMD's (confirmed) deference to AS Media for its Zen chipset design have pointed toward USB3.1 transmission speed degradation issues. The reports indicated a slow-down of USB3.1 speeds as ports are distanced from the chipset, resolvable by motherboard manufacturers with a separate controller for USB3.1. The reports have not presented numbers for the alleged speed degradation; we do not have a clear picture of how heavily – if at all – this rumor impacts USB device speed.
Should USB3.1 transfer speeds truly be impacted this greatly by circuit distance, motherboard manufacturers can opt for inclusion of aftermarket ICs that resolve the issue at increased BOM. There is also still some time prior to mass production and shipping – motherboard manufacturers and AS Media may find a remedy to this reported choke-point by then.
The first “Ask GN” since leaving for PAX East, we delve into topics exploring voltage configurations for overclocking, AMD's Zen / Polaris architectures and the make-or-break pressure, alternatives to FRAPS in DirectX 12/Vulkan, and upgrades.
The questions are posted below the video with timestamps, as always.
For anyone interested in the final question in the video (paraphrased: “Should I buy Polaris or Pascal and sell my 980 Ti?”), you may be interested in our recent “Polaris & Pascal: Buy or Wait?” content we published.
This fifteenth episode of Ask GN springs forth a few quick-hitter questions, but a couple that require greater depth than was addressable in our episodic format. These longer questions will be explored in more depth in future content pieces.
For today, we're looking at the future of AMD's Zen for the company, forecasting HDR and monitor tech, discussing IGP and CPU performance gains, and talking thermals in laptops. As always, one bonus question at the end.
Timestamps are below the embedded video.
The past week of hardware news is mostly industry-driven, with few noteworthy product announcements outside of a few small items. A few critical news items emerged regarding industry, though, like further Samsung vs. nVidia proceedings, Micron's GDDR5X memory (replacing GDDR5, theoretically), Unity's Steam VR support, AMD/HP FreeSync laptops, and AMD Zen details revealed through CERN – the particle and nuclear research group.
We've rounded up this week's news in the below video. You can find quick, bulleted recaps of each item below the video, if you'd prefer that format.

A recent post by Digitimes, known for reporting on leaked or unofficial information, claims that AMD's anticipated Zen architecture is slated for a late 2016 arrival “at the earliest.” This news follows AMD's nearly endless financial spiral, something we reported on earlier this week. The company is now substantially less than the price it paid for ATi in 2006, a purchase that exceeded $5 billion in acquisition cost to AMD.
