The Ultra Ethernet Consortium (UEC) has announced this week that the next-generation interconnection consortium has grown to 55 members. And as the group works towards developing the initial version of their ultra-fast Ethernet standard, they have released some of the first technical details on the upcoming standard.

Formed in the summer of 2023, the UEC aims to develop a new standard for interconnection for AI and HPC datacenter needs, serving as a de-facto (if not de-jure) alternative to InfiniBand, which is largely under the control of NVIDIA these days. The UEC began to accept new members back in November, and just in five months' time it gained 45 new members, which highlights massive interest for the new technology. The consortium now boasts 55 members and 715 industry experts, who are working across eight technical groups. 

There is a lot of work at hand for the UEC, as the group has laid out in their latest development blog post, as the consortium works to to build a unified Ethernet-based communication stack for high-performance networking supporting artificial intelligence and high-performance computing clusters. The consortium's technical objectives include developing specifications, APIs, and source code for Ultra Ethernet communications, updating existing protocols, and introducing new mechanisms for telemetry, signaling, security, and congestion management. In particular, Ultra Ethernet introduces the UEC Transport (UET) for higher network utilization and lower tail latency to speed up RDMA (Remote Direct Memory Access) operation over Ethernet. Key features include multi-path packet spraying, flexible ordering, and advanced congestion control, ensuring efficient and reliable data transfer.

These enhancements are designed to address the needs of large AI and HPC clusters — with separate profiles for each type of deployment — though everything is done in a surgical manner to enhance the technology, but reuse as much of the existing Ethernet as possible to maintain cost efficiency and interoperability.

The consortium's founding members include AMD, Arista, Broadcom, Cisco, Eviden (an Atos Business), HPE, Intel, Meta, and Microsoft. After the Ultra Ethernet Consortium (UEC) began to accept new members in October, 2023, numerous industry heavyweights have joined the group, including Baidu, Dell, Huawei, IBM, Nokia, Lenovo, Supermicro, and Tencent.

The consortium currently plans to release the initial 1.0 version of the UEC specification publicly sometime in the third quarter of 2024.

"There was always a recognition that UEC was meeting a need in the industry," said J Metz, Chair of the UEC Steering Committee. "There is a strong desire to have an open, accessible, Ethernet-based network specifically designed to accommodate AI and HPC workload requirements. This level of involvement is encouraging; it helps us achieve the goal of broad interoperability and stability."

While it is evident that then Ultra Ethernet Consortium is gaining support across the industry, it is still unclear where other industry behemoths like AWS and Google stand. While the hardware companies involved can design Ultra Ethernet support into their hardware and systems, the technology ultimately exists to serve large datacenter and HPC system operators. So it will be interesting to see what interest they take in (and how quickly they adopt) the nascent Ethernet backbone technology once hardware incorporating it is ready.

Wi-Fi 7 products have slowly started gaining market traction, particularly in the residential market (home consumer segment). The SMB / SME / enterprise market is traditionally a few quarters behind this, given the longer validation cycles. Earlier this year, Ubiquiti Networks introduced their first Wi-Fi 7 access point - the U7 Pro. Today, NETGEAR Business is launching the WBE750 Wi-Fi 7 Access Point (AP) in the Pro Wi-Fi lineup for businesses with heavy wireless Internet use.

The benefits of Wi-Fi 7 (802.11be) have been covered in multiple pieces earlier. The presence of a relatively interference-free 6 GHz band, wider channels (up to 320 MHz wide), and technical improvements to address interference and latency make the new standard an attractive upgrade for Wi-Fi users.

Unlike the Ubiquiti UniFi U7 Pro's entry-level focus (with 2x2 configurations in the 2.4 GHz, 5 GHz, and 6 GHz bands), the WBE750 opts for 4x4 configurations in each of the three bands. Correspondingly, the AP is able to support more concurrent connected clients (600 vs. 300), and obviously provide more bandwidth (18.4 Gbps vs. 9.2 Gbps theoretical). The pricing is also correspondingly higher ($700 vs. $190). The WBE750 also incorporates a NBASE-T (10 GbE / 5 GbE / 2.5 GbE / 1 GbE) RJ-45 uplink port with PoE++ support. Eight SSIDs are supported per channel.

Similar to other networking equipment vendors in this space, NETGEAR is also pushing for recurring subscription-based revenue with the product. A 1-year subscription to the single-pane cloud-based management interface (NETGEAR Insight) is included in the $700 purchase price.

NETGEAR Insight is particularly useful for professional installers who can manage multiple sites on the go, even from a mobile device.

The WBE750 joins a number of other Wi-Fi 6 / 6E APs in the Pro Wi-Fi line serving a wide range of deployment requirements. NETGEAR has been introducing multiple products in their Insight-manageable line over the last few quarters. As a result, they are able to offer a total network solution (gateways / routers / switches / APs) that can be managed from a single pane. As part of its Pro focus, NETGEAR is offering free site design services to installers along with expert technical support. NETGEAR's Pro WiFi Design Services (network design, product selection guide, troubleshooting, and training support) aims to be a key differentiation aspect compared to other similar offerings in the SMB / SME market.

The WBE750 is powered by a Qualcomm solution - the Waikiki Wi-Fi 7 chipset incorporated in the Networking Pro 1220 platform.

The new WBE750 AP is available for purchase today for $700.

Corsair has launched its latest Hydro X series iCUE LINK XH405i RGB custom open-loop water cooling kits, replacing the older XH305i kits from 2020. The new kits feature Corsair’s latest XD5 RGB ELITE pump and reservoir, the XC7 RGB ELITE CPU waterblock, three QX120 RGB fans, and a 360mm radiator. The pump, waterblock, and fans all have the namesake iCUE LINK integration, which Corsair has been pushing throughout its entire recent generation of products.

The biggest hardware-related difference between XH405i kits and previous generation XH305i kits is undoubtedly the inclusion of iCUE LINK hardware, which Corsair recently debuted with its iCUE LINK H150i RGB AIO cooler. iCUE LINK allows individual Corsair cooling components within a system to be directly connected, primarily cutting down on cable clutter, but also offering the promise of more and finer-grained control over individual components via the iCUE LINK Hub at the center of a system. For instance, each individual iCUE LINK-compatible fan connected to the iCUE LINK hub can be set to its own speed, rather than either requiring each fan to be connected to its own fan header on the motherboard or setting a common speed for all fans via a multi-headed cable.

The XH405i is offered in two themes: stealth gray and white. Outside of cosmetics, the two variants are the same and come with a combined pump and reservoir, a CPU waterblock compatible with the AM5 and LGA 1700 sockets, three 120mm fans, a 360mm radiator, and a central iCUE LINK Hub. The kits also come with all the accessory components needed to build a custom loop: hardline tubing, a bending kit, fittings, and XL8 clear-colored coolant. These kinds of kits are usually geared towards newcomers to custom liquid cooling and users who need a brand-new loop but don’t want to spend much time scouring for individual components.

Separately, Corsair has also launched the iCUE LINK XG7 RGB GPU waterblock for GeForce RTX 4090 and 4080 Super graphics cards. As is typically the case for full-coverage GPU waterblocks, the XG7 has specific hardware compatibility requirements, and as a result Corsair is making four versions of the waterblock. The company is targetting ASUS’s ROG STRIX and TUF cards, as well as MSI’s SUPRIM and GAMING TRIO lineups, offering RTX 4090 and RTX 4080 blocks for each of those card families. Just like the other components in the XH405i kit, the GPU waterblock is also iCUE LINK-equipped.

Aimed at a premium market, the full XH405i kit doesn't come cheap: Corsair has set the MSRP at $700 for the complete cooling collection. Meanwhile, the XG7 GPU waterblock is priced at $230 for all four models.

The iCUE LINK XH405i kit is available now at Newegg and Amazon, as well as through Corsair’s own website.

Today NVIDIA has brought variable refresh rate support to its GeForce Now cloud gaming service. The company initially promised variable refresh support on GeForce Now back in early January during CES, and has seemingly waited so that it could launch alongside GeForce Now Day Passes, which are also now available.

Variable refresh rate (VRR) technologies, including NVIDIA's own G-Sync, have been around for around a decade now, and allow a monitor to synchronize its refresh rate to the instantaneous framerate of a game. This synchronization prevents screen tearing, when two or more frames are present on a display at the same time. Without a VRR technology, gamers either have to tolerate the visual incongruity of screen tearing or enable V-Sync, which solves screen tearing by locking the framerate to the refresh rate (or a fraction thereof). VRR became popular because V-Sync added latency and could depress framerates due to it effectively being a framerate limiter.

Dubbed "Cloud G-Sync", NVIDIA touts not only a screen tearing-free experience for GeForce Now thanks to variable refresh rate support, but also lower latency thanks to “varying the stream rate to the client, driving down total latency on Reflex-enabled games.” Prior to VRR’s debut on GeForce Now, users either had to enable V-Sync in-game, enable a stream-level V-Sync setting that had the benefit of not locking the game framerate, or accept screen tearing. GeForce Now Ultimate members will also be able to pair VRR with Reflex-powered 60 FPS and 120 FPS streaming modes.

According to NVIDIA’s technical documentation, variable refresh rate support on GeForce Now can work with both Mac and Windows PCs hooked up to a VRR-capable monitor. This includes G-Sync monitors on Windows, as well as VESA AdaptiveSync/FreeSync monitors, HDMI 2.1 VRR displays, and even Apple ProMotion displays, such as the panels built into their recent MacBook Pro laptops. The biggest compatibility hurdle at this time is actually on the GPU side of matters; Windows machines need an NVIDIA GPU to use VRR with GeForce Now. Intel and AMD GPUs are "not supported at this time."

Although G-SYNC originally came out in 2013 and GeForce Now has been available since 2015, the two never intersected until now. It’s not clear why NVIDIA waited so long to bring G-Sync to GeForce Now; the company’s original announcement merely states “newly improved cloud G-SYNC technology goes even further,” implying that it wasn’t possible before but doesn’t exactly explain why.
