With PC motherboard manufacturers implementing 40 Gbps USB4, one wonders what's next for the [mostly] universal connectivity standard. Turns out, it is USB4 2.0, which yields the connector 80 Gbps of data bandwidth per direction, and 60 W of power-delivery (PD). Power delivery for USB4 2.0 can be as high as 240 W (48 V, 5 A). Japanese PC peripherals maker Elecom is the first with certified cables for both 80 Gbps + 60 W PD and 80 Gbps + 240 W PD. Besides power and data, both cables support DisplayPort passthrough for up to 8K @ 60 Hz (7680 x 4320 pixels). USB-IF, the governing body of the USB standard, is expected to formally launch USB4 2.0 in December 2024. A typical USB4 2.0 host controller will require at least a PCI-Express 5.0 x4 system bus connection to reach the standard's maximum bandwidth.

Intel's next-generation Xe2 "Battlemage" graphics architecture is expected to introduce a significant update to the display engine over the current Xe "Alchemist." The display engine handles the various display I/O of the GPU. For most users with a single display that's running at or under 4K @ 60 Hz, this is irrelevant, however, as your resolution, refresh-rates, color bit-depth, and dynamic-range go up, some of the newer display connector formats become relevant. Intel beat both NVIDIA and AMD to be the first GPU maker to implement DisplayPort 2.1 albeit with a UHBR10 link layer (which is needed for DP 2.1). The DP 2.1 spec prescribes certain optional higher link layer bit-rates, such as UHBR13.5 and UHBR20. AMD was the first to implement UHBR13.5 and UHBR20 with the Radiance display engine in its RDNA 3 GPUs, and we're learning that Intel wants to catch up.

Driver patch notes unearthed by Phoronix find references to Arc "Battlemage" GPUs supporting UHBR13.5. These drivers are believed to have previously supported UHBR20, but support for the higher bit-rate was removed from the current version of drivers. It indicates that Intel is still evaluating the higher bit-rates on its unreleased GPUs, and production-ready versions could implement at least UHBR13.5. DisplayPort 2.1 with UHBR13.5 (13.5 Gbps per lane), over a DP80-ready DisplayPort cable yields a maximum resolution of uncompressed 8K @ 60 Hz with HDR, or 4K @ 240 Hz with HDR. Intel is expected to debut "Battlemage" with its Core Ultra 200-series "Lunar Lake" mobile processors, later this year.

IOGear unveiled a handful products relevant to content creators and creative professionals on the move, at the 2024 International CES. The star attraction here is the Quantum Thunderbolt 5 Dock Pro. It plugs into a Thunderbolt 5 upstream port, putting out three Thunderbolt 5 downstream ports, with display passthrough of dual 8K @ 60 Hz or triple 4K @ 120 Hz. The dock doesn't support the 120 Gbps Bandwidth Boost feature being mooted by Intel, but you'll definitely get 80 Gbps per direction. Also shown was the Quantum Thunderbolt 4 Mini Dock, which supports up to one 8K @ 30 Hz display stream or dual 4K @ 60 Hz, within its 40 Gbps switching bandwidth. Both docks are TAA compliant.

Next up, we have the IOGear Upstream Pro 4-port HDMI to UVC mixer, which mixed and captures non-DRM HDMI inputs to PGM UVC video at resolutions of up to 4K @ 30 Hz. The Upstream Pro Seamless 2-port webcam matrix lets you switch between multiple web cameras within a live stream, so you can change the shot while you're live. There are also some handy adapters and cables. IOGear specializes in ports, cables and adapters of all shapes and sizes.

ORICO unveiled the first USB type-C cable that meets USB4 and Thunderbolt 4 standards. The cable utilizes an Intel IC to offer 40 Gbps transfer speeds, DisplayPort 1.4 passthrough with support for display resolutions of up to 8K @ 60 Hz, and bi-directional 100 W USB PD (power delivery). The cable features a solid alloy casing at the connectors, Nylon braiding throughout, and a reinforced bender that can take up to 10,000 bends. Available in cable lengths of 30 cm, 80 cm, and 2 m, the cable comes in two variants based on connector orientation, with the TBZ cable being standard, and TBW angled 90°. The 30 cm variant is priced at $20, the 80 cm variant at $27, and the 2 m variant at $57. Find them on Amazon here.

ORICO unveiled a pair of innovating new storage and connectivity products over the last week. These include the TB3-S2 portable Thunderbolt docking station, and the PSSD portable SSD featuring fingerprint-based biometric security. The TB3-S2 is a compact multi-function docking station that measures 188 mm x 95 mm x 24 mm (WxDxH). It takes in a Thunderbolt 3 (40 Gbps) connection, and can daisy-chain it onward to another Thunderbolt 3 port with full 8K @ 60 Hz capability (depending on the input).

The box draws power from a 120 W power brick. Inside, you'll find two M.2-2280 NVMe slots that can hold up to 4 TB of storage. The display input from the Thunderbolt 3 port is put out as a standard DisplayPort 1.3. There are a boat-load of downstream connectivity options, which include two 10 Gbps USB 3.2 Gen 2 ports (from which one is type-C), two 5 Gbps USB 3.2 Gen 1 type-A ports, a 60-Watt/15-Watt USB-PD port (purely for power delivery), a 1 GbE wired Ethernet interface, and a 2-channel audio with mic-input (USB DAC). Available now, the TB3-S2 is priced at USD $399.99.

Over three years after the launch of the HDMI Specification Version 2.1, major products are now widely available that support HDMI 2.1 features including 4K@120Hz, 8K@60Hz, Dynamic HDR and eARC. Instead of asking when HDMI 2.1-enabled products will be available, people are now asking for advice about which new HDMI 2.1-enabled products to buy.

"It's exciting to see so many new products available with these new features," said Rob Tobias, CEO and president of HDMI Licensing Administrator, Inc. (HDMI LA). "And with the launch of the latest gaming consoles, consumers can now enjoy a thrilling HDMI 2.1 end-to-end experience with consoles, AVR's, cables, TVs and monitors. With shipments of HDMI products reaching almost 10 billion since it launched in 2002, HDMI technology continues to be the universal interface for consumer electronics products."
