The revised spec brings the JEDEC standard up to the level we saw with Samsung's "Aquabolt" HBM2 and its 307.2 GB/s per-stack bandwidth, but with 12-high TSV stacks (up from 8) which raises memory capacity from 8GB to a whopping 24GB per stack.
The full press release from JEDEC follows:
ARLINGTON, Va., USA – DECEMBER 17, 2018 – JEDEC Solid State Technology Association, the global leader in the development of standards for the microelectronics industry, today announced the publication of an update to JESD235 High Bandwidth Memory (HBM) DRAM standard. HBM DRAM is used in Graphics, High Performance Computing, Server, Networking and Client applications where peak bandwidth, bandwidth per watt, and capacity per area are valued metrics to a solution’s success in the market. The standard was developed and updated with support from leading GPU and CPU developers to extend the system bandwidth growth curve beyond levels supported by traditional discrete packaged memory. JESD235B is available for download from the JEDEC website.
JEDEC standard JESD235B for HBM leverages Wide I/O and TSV technologies to support densities up to 24 GB per device at speeds up to 307 GB/s. This bandwidth is delivered across a 1024-bit wide device interface that is divided into 8 independent channels on each DRAM stack. The standard can support 2-high, 4-high, 8-high, and 12-high TSV stacks of DRAM at full bandwidth to allow systems flexibility on capacity requirements from 1 GB – 24 GB per stack.
This update extends the per pin bandwidth to 2.4 Gbps, adds a new footprint option to accommodate the 16 Gb-layer and 12-high configurations for higher density components, and updates the MISR polynomial options for these new configurations. Additional clarifications are provided throughout the document to address test features and compatibility across generations of HBM components.

AMD today released the latest major update to its Radeon software and driver suite. Building on the groundwork laid last year, AMD Radeon Software Adrenalin 2019 Edition brings a number of new features and performance improvements.
With this year’s software update, AMD continues to make significant gains in game performance compared to last year’s driver release, with an average gain of up to 15 percent in across a range of popular titles. Examples include Assassin’s Creed Odyssey (11%), Battlefield V (39%), and Shadow of the Tomb Raider (15%).
Beyond performance, Adrenalin 2019 Edition introduces a number of new and improved features. Highlights include:
Game Streaming: Radeon gamers can now stream any game or application from their PCs to their mobile devices via the AMD Link app at up to 4K 60fps. The feature supports both on-screen controls as well as Bluetooth controllers. ReLive streaming is also expanding to VR, with users able to stream games and videos from their PCs to standalone VR headsets via new AMD VR store apps. This includes Steam VR titles, allowing users to play high-quality PC-based VR games on select standalone headsets. AMD claims that its streaming technology offers “up to 44% faster responsiveness” than other game streaming solutions.
ReLive Streaming and Sharing: Gamers more interested in streaming their games to other people will find several new features in AMD’s ReLive feature, including adjustable picture-in-picture instant replays from 5 to 30 seconds, automatic GIF creation, and a new scene editor with more stream overlay options and hotkey-based scene transition control.
Radeon Game Advisor: A new overlay available in-game that helps users designate their target experience (performance vs. quality) and then recommends game-specific settings to achieve that target. Since the tool is running live alongside the game, it can respond to changes as they occur and dynamically recommend updated settings and options.
Radeon Settings Advisor: A new tool in the Radeon Software interface that scans system configuration and settings and recommends changes (e.g., enabling or disabling Radeon Chill, changing the display refresh rate, enabling HDR) to achieve an optimal gaming experience.
WattMan One-Click Tuning Improvements: Radeon WattMan now supports automatic tuning of memory overclocking, GPU undervolting, expanded fan control options, and unlocked DPM states for RX Vega series cards.
Display Improvements: FreeSync 2 can now tone-map HDR content to look better on displays that don’t support the full color and contrast of the HDR spec, and AMD’s Virtual Super Resolution feature is now supported on ultra-wide displays.
Radeon Overlay: AMD’s Overlay feature which allows gamers to access certain Radeon features without leaving their game has been updated to display system performance metrics, WattMan configuration options, Radeon Enhanced Sync controls, and the aforementioned Game Advisor.
AMD Link: AMD’s mobile companion app now offers easier setup via QR code scanning, voice control of various Radeon and ReLive settings (e.g., start/stop streaming, save replay, take screenshot), WattMan controls, enhanced performance metrics, and the ability to initiate a Radeon Software update.
Radeon Software Adrenalin 2019 Edition is available now from AMD’s support website for all supported AMD GPUs.

The majority of today's news will cover Intel's wide range of announcements from their architecture day, with new Optane DIMMs seeking to reduce latency to come close to matching that of DRAM to Foveros chiplets and hints of coming in off the Lake to spend some time in a Sunny Cove. Indeed there are more links below the fold offering more coverage as yesterdays announcements were very dense.
That might overshadow a rumour which dedicated discrete GPUs lovers would be interested in, the fact that NVIDIA might be able to get the RTX 2060 to market before AMD can launch a Navi based card. The Inquirer has seen rumours that NVIDIA might be able to release the card in the first half of 2019, while the 7nm Navi isn't expected until the second half of year. The early supply of mid-range NVIDIA GPUs might attract buyers who no longer want to wait; though depending on how Navi performs they could come to regret that lack of patience.
"GRAPHICS CARDS IN 2019 are set to get a good bit more interesting, as a leak suggests that Nvidia's GeForce RTX 2060 could reach the market before AMD's next-gen Navi Radeon cards."

Vega meets Radeon Pro
Professional graphics cards are a segment of the industry that can look strange to gamers and PC enthusiasts. From the outside, it appears that businesses are paying more for almost identical hardware when compared to their gaming counterparts from both NVIDIA and AMD.
However, a lot goes into a professional-level graphics card that makes all the difference to the consumers they are targeting. From the addition of ECC memory to protect against data corruption, all the way to a completely different driver stack with specific optimizations for professional applications, there's a lot of work put into these particular products.
The professional graphics market has gotten particularly interesting in the last few years with the rise of the NVIDIA TITAN-level GPUs and "Frontier Edition" graphics cards from AMD. While lacking ECC memory, these new GPUs have brought over some of the application level optimizations, while providing a lower price for more hobbyist level consumers.
However, if you're a professional that depends on a graphics card for mission-critical work, these options are no replacement for the real thing.
Today we're looking at one of AMD's latest Pro graphics offerings, the AMD Radeon Pro WX 8200.

The logo, with the familiar "V" joined by a couple of new stripes on the right side, could mean a couple of things; with a possible reference to Vega II (2), or perhaps the VII suggests the Roman numeral 7 for 7nm, instead? VideoCardz.com thinks the latter may be the case:
"AMD has registered a new trademark just 2 weeks ago. Despite many rumors floating around about Navi architecture and its possible early reveal or announcement in January, it seems that AMD is not yet done with Vega. The Radeon Vega logo, which features the distinctive V lettering, has now received 2 stripes, to indicate the 7nm die shrink."
Whatever the case may be it's interesting to consider the possibility of a 7nm Vega GPU before we see Navi. We really don't know, though it does seem a bit presumptuous to consider a new product as early as CES, as Tech Radar speculates:
"We know full well that the next generation of AMD graphics will be built upon a 7nm architecture going by the roadmaps the company released at CES 2018. At the same time, it seems to all sync up with AMD's plans to announce new 7nm GPUs at CES 2019, so it almost seems certain that we’ll see Vega II graphics cards soon."
The prospect of new graphics cards is always tantalizing, but we'll need more than a logo before things really get interesting.

The discovery of yet another variant of Spectre vulnerability is not good news for already exhausted security experts or reporters, but there is something new in this story which offers a glimmer of hope. A collaborative team of researchers from Northeastern University and IBM found this newest design law using an automatic bug finding tool they designed, called Speculator.
They designed the tool to get around the largest hurdle security researchers face, the secrecy of AMD, Intel and ARM who are trying to keep the recipe for their special sauce secret, and rightly so. Protecting their intellectual properly is paramount to their stockholders and there are arguments about the possible effectiveness of security thorough obscurity in protecting consumers from those with nefarious intent but it does come at a cost for those hunting bugs for good.
"SplitSpectre is a proof-of-concept built from Speculator, the team's automated CPU bug-discovery tool, which the group plans to release as open-source software."

If the rumours The Inquirer are helping spread are true then AMD really does believe the third time's the charm. The new series of Ryzen 3000 chips will use Zen 2 cores and will follow Intel's addition of a 9 series, though the quoted price of £400 for the Ryzen 9 3850X is a lot more attractive than Intel's pricing. That chip will sport a 5.1GHz peak clock on its pair of Zen 2 dies with eight cores apiece, though the 135W TDP will need some taming.
Check out the variety of other chips in the Ryzen 3, 5, and 7 families which have leaked out.
"The upcoming third-generation Ryzen chip, slated for release next year, will be based on Team Red's Zen 2 architecture, the successor to its rather successful Zen architecture found in Ryzen 1 and 2 CPUs and EPYC server processors."
