GPMI Replaces HDMI & DisplayPort, Supports 192 Gbps, 480W Power
GPMI: New Interface Aims to Surpass displayport and HDMI
Table of Contents
A consortium of over 50 Chinese tech companies, operating under the Shenzhen 8K UHD Video Industry Cooperation Alliance, is developing a new interface called GPMI (likely standing for General Purpose Media Interface) that seeks to outperform existing DisplayPort and HDMI standards. The alliance claims GPMI offers superior data transfer rates and power delivery capabilities.
GPMI Specifications and Potential Advantages
The GPMI standard supports both native connectors (Type-B) and USB-C (Type-C) implementations. According to the alliance, GPMI type-C, utilizing USB-C, can achieve data transfer rates of 96 GB/s and deliver 240W of power. In contrast, the current DisplayPort 2.1 UHBR20, also via USB-C, manages 80 GB/s with the same 240W power delivery.
The native GPMI connector (Type-B) purportedly boasts even higher performance, reaching 192 GB/s and delivering up to 480W of power. DisplayPort 2.1 with a native connector (Type-B) does not offer power delivery and remains capped at 80 GB/s. HDMI 2.1, in comparison, tops out at 48 GB/s and does not support power delivery.
Interface comparison
| Interface | Data Transfer Rate | Power Delivery |
|---|---|---|
| GPMI Type-B | 192 GB/s | 480 W |
| GPMI Type-C (USB-C) | 96 GB/s | 240 W |
| DisplayPort 2.1 UHBR20 | 80 GB/s | – |
| DisplayPort 2.1 UHBR20 (USB-C USB4 V2) | 80 GB/s | 240 W |
| HDMI 2.1 FRL | 48 GB/s | – |
| HDMI 2.1 TMDS | 18 GB/s | – |
| Thunderbolt 4 | 40 GB/s | 100 W |
| Thunderbolt 5 (USB-C USB4 V2) | 80 GB/s | 240 W |
| USB4 | 40 GB/s | 240 W |
Adoption and Potential Use Cases
While the GPMI standard offers the flexibility of both native and USB-C connectors,using the latter reduces the transfer rate and power delivery capabilities by half. Though, the USB-C option provides compatibility with existing devices and a smaller connector size suitable for mobile applications.
Several major television manufacturers, including Huawei, Skyworth, Hisense, and TCL, have reportedly confirmed plans to incorporate GPMI into upcoming smart TV models.
The primary goal of GPMI appears to be consolidating power and data transmission into a single cable, eliminating the need for separate power and display connections. This could simplify device connectivity and perhaps pave the way for innovations such as powering graphics cards directly from a monitor.
GPMI: everything You Need to Know About the New Interface
Tired of multiple cables cluttering your setup? Want faster data transfer and more power delivery? The GPMI (General purpose Media Interface) standard, spearheaded by a consortium of Chinese tech companies, promises all that and more. LetS dive into the details with a complete Q&A.
What is GPMI?
Q: What is GPMI?
A: GPMI, short for General Purpose Media Interface, is a new interface being developed by a group of over 50 Chinese tech companies. The goal is to create a single cable solution for high-speed data transfer and power delivery, possibly replacing existing standards like DisplayPort and HDMI.
Q: Why is GPMI being developed?
A: GPMI aims to simplify device connectivity and improve performance. It’s designed to consolidate power and data transmission into a single cable. This could make connecting devices easier and enable innovations that would otherwise be arduous, such as powering high-end graphics cards directly from a monitor.
GPMI’s Technical Specifications
Q: What are the key specifications of GPMI?
A: GPMI offers impressive specifications,especially compared to existing standards. Here’s a breakdown:
- Native Connector (Type-B): Boasts data transfer rates up to 192 GB/s and power delivery up to 480W.
- USB-C Connector (Type-C): Achieves data transfer rates of 96 GB/s and power delivery up to 240W.
Q: How do GPMI’s specifications compare to DisplayPort and HDMI?
A: The specs are quite compelling. Here’s a comparison table:
| Interface | Data Transfer Rate | Power delivery |
|---|---|---|
| GPMI Type-B | 192 GB/s | 480 W |
| GPMI Type-C (USB-C) | 96 GB/s | 240 W |
| DisplayPort 2.1 UHBR20 | 80 GB/s | – |
| DisplayPort 2.1 UHBR20 (USB-C USB4 V2) | 80 GB/s | 240 W |
| HDMI 2.1 FRL | 48 GB/s | – |
| HDMI 2.1 TMDS | 18 GB/s | – |
| Thunderbolt 4 | 40 GB/s | 100 W |
| Thunderbolt 5 (USB-C USB4 V2) | 80 GB/s | 240 W |
| USB4 | 40 GB/s | 240 W |
Q: What is the difference between GPMI Type-B and Type-C connectors?
A: GPMI supports both native (Type-B) and USB-C (Type-C) connectors. While GPMI Type-B provides the highest performance (192 GB/s and 480W), the Type-C connector, using the USB-C standard, offers the convenience of compatibility with existing devices and a smaller form factor, especially useful for mobile applications. However, Type-C’s transfer rate and power delivery are reduced compared to native GPMI.
Adoption and Potential Use Cases
Q: Which companies are adopting GPMI?
A: Several major television manufacturers, including huawei, Skyworth, Hisense, and TCL, have reportedly confirmed plans to incorporate GPMI into upcoming smart TV models.
Q: What are some potential use cases for GPMI?
A: the primary use case is simplifying the connection of power and data into a single cable. This could lead to several exciting possibilities.
