Light peak 1 Thunderbolt Intel

Intel has refreshed its Tall Ridge line of Thunderbolt 3 controllers with a new pair of products, codenamed Titan Ridge. The JHL7540, 7440, and 7340 are drib-in replacements for the JHL6x40 family and offer a unmarried low-bandwidth Thunderbolt 3 port, a single high-bandwidth TB3 port, or a pair of Thunderbolt 3 ports.

There are two features that set the new controllers autonomously from Intel's older variants. First, they nudge support for Thunderbolt three's DisplayPort standard from version i.2 to version 1.4. No mention is made of whether the new controllers support Adaptive Sync, the optional feature that enables FreeSync and was added in DP1.2a. Presumably, they don't. DisplayPort one.3 added the ability to handle a 120Hz 4K panel, a 10-scrap 5K panel @ 60Hz, or even an 8K panel @ 30Hz.

Thunderbolt tin can also exist used to daisy chain devices, as shown here.

DisplayPort one.four keeps the bandwidth transmission capabilities of DP i.3 but adds Display Stream Pinch support, Forrad Error Correction, HDR10, Rec. 2020 colour, and up to 32 audio channels. It can also exist used to 8K panels @ 60Hz with x-flake color support. Information technology'south pretty common for standards to add together support for resolutions and operating modes that most monitors don't initially back up, but devices that incorporate Titan Ridge Thunderbolt controllers going forrard should be loaded for bear, equally far as future standards and capabilities are concerned.

Improved USB-C Compatibility

When Thunderbolt 3 adopted USB-C it was initially hailed as an extremely smart move for Intel. Over the past few years, we've seen the downside of packing and then many dissimilar versions of a single cablevision blazon into one interface. The problem isn't that USB-C is bad; the problem is that there are a number of unlike USB-C flavors that aren't properly conveyed or explained to customers. With Titan Ridge, Intel seems to be hoping to cut down on the confusion. Here's what the company says:

The JHL7440 controller was specifically designed for Thunderbolt 3 monitor and enterprise dock makers who cull to offering basic compatibility when a Thunderbolt three monitor or dock is continued to a USB-C computer port. To attain this, the JHL7440 controller integrates USB-C figurer port compatibility then a Thunderbolt three monitor or dock can intelligently provide more than performance and features when connected to a Thunderbolt 3 calculator port, and basic compatibility when the Thunderbolt three monitor or dock is continued to a USB-C computer port. Additionally, as with the other controllers in the JHL7x40 series, the JHL7440 supports DisplayPort 1.4.

This seems to imply that this new capability is unique to the JHL440 controller. This could mean that Intel developed the option specifically to entreatment to OEMs that want to include Thunderbolt 3 just demanded a more than uniform choice. Unfortunately, further information on what features are supported in basic compatibility manner are unclear, only if nosotros had to guess, here's our bet: The 5-10Gbit/south operation of USB 3.0 / 3.1 Gen 2 isn't enough to bulldoze a display at ultra-high resolutions with high refresh rates, just it's more than than enough for a basic panel. We don't know what the cutting-offs or ranges are, simply it makes sense to call back Intel added the ability to back up panels of upward to a certain resolution and color depth. This kind of improved compatibility could exist a sign manufacturers want to send the standard more widely.
