While the difference between 8K and 4K resolution is great when comparing the number of pixels in each, it's nearly invisible to the naked eye. What really makes all the difference is the speed provided by the major increase in the 8K cable’s bandwidth. 8K’s higher resolution and frame rate require more data than 4K, and since a cable’s bandwidth regulates how much data the cable can transfer, HDMI 2.1 opens the throttle.
Boasting speeds of up to 48Gbps, 8K cables deliver data at more than twice the speed of 4K cables, which transfer data up to 18.2Gbps. Think of the 8K cable as a six-lane highway and the 4K cable as a two-lane highway. The six-lane highway can not only accommodate more traffic, but, when the same amount of traffic is traveling down each of those two highways, the traffic can flow much faster using six lanes instead of two.
4K HDMI 2.0 cables deliver 4K at 60 frames per second (fps), while 8K HDMI 2.1 cables deliver 8K content at 60fps or 4K content at 120fps, since less data is required to transmit 4K content. The bottom line is that if you have 4K content, you’ll get twice the frames per second using an 8K cable. We’re talking real-time gameplay, low latency and lag-free gaming. This makes 8K the clear choice for setups compatible with HDMI 2.1.
As mentioned earlier, 8K HDMI 2.1 has many benefits over 4K HDMI 2.0. While I won’t highlight every feature HDMI 2.1 brings to the table, I will address several features that, in addition to its incredible bandwidth, make it well worth the investment over HDMI 2.0 cables.
Feature | 4K HDMI 2.0 | 8K HDMI 2.1 |
Maximum bandwidth | 18Gbps | 48Gbps |
Maximum video resolution | 4K@60Hz | 4K@120Hz or 8K@60Hz |
Maximum frame rate | 4K@60fps | 4K@60fps or 8K@120fps |
Maximum refresh rate | 60Hz | 120Hz |
HDR | Static | Dynamic |
Game mode variable refresh rate | No | Yes |
eARC | No | Yes |
While we could assume that all HDMI 2.1 cables include all of the features mentioned here and more, that’s not the case. To ensure you’re getting the best of the best with all that HDMI 2.1 has to offer, check the cable’s specifications and look for the Ultra Certified Cable label on the packaging. This label includes a QR code to help you identify HDMI cables that have met rigorous testing standards established by the HDMI Forum. Simply scan the HDMI label’s QR code using the HDMI Cable Certification app, available for both iOS and Android devices.
If you’re ready to upgrade your gaming setup, check out these 8K HDMI 2.1 cables from Titan. They’re available in various lengths and meet full HDMI 2.1 certification. What sets them apart, however, is their unique design. Titan 8K HDMI 2.1 cables feature a futuristic look that incorporates amber LEDs on each cable head that glow when they're connected to powered equipment. They not only add a splash of color to your gaming setup, but also help you easily identify connected equipment. The Titan brand is designed by gamers for gamers and includes a growing family of products built to empower the player.
