He never said that IIRC, all he said was that some older engines favor wide and slow and some older engines favor fast and narrow. He made no definitive statement on what future engines will rely on more heavily either.
Edit:
PC RDNA 2 such as RX 6800/6900 series has both wide and high clock speeds.
You have no clue what you are talking about. Sony's TV's since 2020 has had HDMI 2.1 but no VRR. It is about the chipset being used, not just because it has HDMI 2.1. Having 2.1 does not automatically mean you get all the benefits of 2.1. Companies like Sony are still trying to shoehorn VRR into the existing 2.1 chipset they have.
So in short, just because a TV has HDMI 2.1 ports, DOES NOT mean they support the full suite of HDMI 2.1 features.
HDMI Licensing Administrator has allowed HDMI 2.0a/2.0b to be marketed as HDMI 2.1.

"Fake HDMI 2.1" and the Start of the Confusion
The display that prompted this investigation was from Chinese manufacturer mi.com, and was their so-called "
Xiaomi Fast LCD Monitor 24.5-inch 240Hz version". This is a 24.5" sized display with a 1080p resolution and 240Hz refresh rate. At the bottom of their product page they list inclusion of 2x HDMI 2.1 ports:
However, beneath that at the bottom of the page hidden in the terms and conditions they then say the following (translated):
"Due to the subdivision of HDMI certification standards, HDMI 2.1 is divided into TMDS (the bandwidth is equivalent to the original HDMI 2.0 and FRL protocols). The HDMI 2.1 interface of this product supports the TMDS protocol, the maximum supported resolution is 1920×1080, and the maximum refresh rate is 240Hz."
We contacted HDMI.org who are the "HDMI Licensing Administrator" to ask some questions about this new standard, seek clarification on several questions we had and discuss the Xiaomi display we mentioned above. Here is what we were told:
- HDMI 2.0 no longer exists, and devices should not claim compliance to v2.0 as it is not referenced anymore
- The features of HDMI 2.0 are now a sub-set of 2.1
- All the new capabilities and features associated with HDMI 2.1 are optional (this includes FRL, the higher bandwidths, VRR, ALLM and everything else)
- If a device claims compliance to 2.1 then they need to also state which features the device supports so there is "no confusion"
------
HDMI 2.1 is meaningless.
Video Electronics Standards Association (VESA)'s Display Port is a better certification standard.
NVIDIA's RTX Ampere has the "Full HDMI 2.1" 48 GBps including all the
optional features. AMD's PC RDNA 2 and Xbox Series X are second best with HDMI 2.1" 40 GBps including most of the
optional features.

HDMI Licensing Administrator defined HDMI 2.1A
- Higher video resolutions support a range of high resolutions and faster refresh rates including 8K60Hz and 4K120Hz for immersive viewing and smooth fast-action detail. Resolutions up to 10K are also supported for commercial AV, and industrial and specialty usages.
- Dynamic HDR support ensures every moment of a video is displayed at its ideal values for depth, detail, brightness, contrast and wider color gamuts—on a scene-by-scene or even a frame-by-frame basis.
- Source-Based Tone Mapping (SBTM) is a new HDR feature that allows a portion of the HDR mapping to be performed by the Source device instead of the Display device. SBTM is especially useful in cases where HDR and SDR video or graphics are combined together into a single picture, such as picture-in-picture or a program guide with an integrated video window. SBTM also enables PCs and gaming devices to automatically produce an optimized HDR signal in order to maximize the utilization of the display's HDR capabilities without manual user configuration of the Source device.
- The Ultra High Speed HDMI Cable supports the 48G bandwidth for uncompressed HDMI 2.1a feature support. The cable also features very low EMI emission and is backwards compatible with earlier versions of the HDMI Specification and can be used with existing HDMI devices.
- eARC simplifies connectivity, provides greater ease of use, and supports the most advanced audio formats and highest audio quality. It ensures full compatibility between audio devices and upcoming HDMI 2.1a products.
- Enhanced gaming features ensure an added level of smooth and seamless motion and transitions for gaming, movies and video. They include:
- Variable Refresh Rate (VRR) reduces or eliminates lag, stutter and frame tearing for more fluid and better detailed gameplay.
- Auto Low Latency Mode (ALLM) allows the ideal latency setting to automatically be set allowing for smooth, lag-free and uninterrupted viewing and interactivity.
- Quick Frame Transport (QFT) reduces latency for smoother no-lag gaming, and real-time interactive virtual reality.
- Quick Media Switching (QMS) for movies and video eliminates the delay that often occurs when a device changes from one HDMI frame rate to another.
- HDMI Cable Power enables active HDMI Cables to be powered directly from the HDMI Connector, without attaching a separate power cable. This makes attaching and using active HDMI Cables as easy as using passive, wired HDMI Cables.
