Intel Arc A380 supports DisplayPort 2.0
The Intel Arc A380, leaked a few weeks ago in the Chinese market, has aroused interest both for the low selling price and at the same time for the features it is equipped with, starting with the proprietary technologies for AI-assisted upscaling, the XeSS and Deep Link. Among these, the card also offers support for the new DisplayPort 2.0 standard, with which it is possible to connect monitors with higher refresh rates and resolutions.The first model to offer this possibility is the Arc A380 Photon made by GUNNIR, which appeared just last week in independent benchmarks performed by a user. This GPU offers a total of four video outputs, including three DisplayPort 2.0 connectors and one HDMI 2.0. Each of the DisplayPorts featured offers different UHBR10, UHBR13.5 and UHBR20 performance levels. Just this last step would be able to reach, at least according to MyDrivers estimates, a maximum bandwidth of 80Gbps, far exceeding the performance offered by HDMI 2.1, only able to reach a speed of 48 Gbps.

In addition to Intel's Arc Alchemist GPUs, support for Display Port 2.0 should also be present on future Radeon RX 7000 . AMD's video cards, expected to launch between October and November, will be produced through TSMC's 5nm production node to benefit from a 50% performance per watt increase, a path opposite to that taken by Nvidia with the sue GeForce RTX 4000.
Intel Arc A380 Performs Pretty Bad with AMD CPUs
A recent set of benchmarks found on bilibili, Intel's Arc A380 cards perform more rancid with an AMD Ryzen 5 5600 than with an Core i5-12400 CPU. The card was tested on an ASUS TUF B550M motherboard with 16 GB of DDR4 3600 MHz RAM.
Both test platforms enable auto-resizable BARs and 4G decoding. Both machines were running Windows 11 21H2. With the exception of League of Legends, AMD trailed Intel by 1% to 15% in every of the 10 gamer. Forza Horizon 5 and Total War: Three Kingdoms trailed by 14 to 15%. League of Legends, Dota 2, Rainbow 6 Extraction, Watch Dogs Legions, Far Cry 6, Assassin's Creed Valhalla, Total War Three Kingdoms,
Shadow of the Tomb Raider, CS:GO, and Forza Horizon 5 were all put through rigorous testing. An NVIDIA GeForce GTX 1650 was also tested, but solely on the Intel-based machine, and the Arc A380 outperformed it by 7% in Total War Three Kingdoms. Combining Intel Arc graphics cards and AMD processors appears to be a bad idea (for the time being).

Since there is a title where AMD CPU offered the better result, it already tells that this behavior is not on purpose. They have yet many bigger problems to deal with before focusing on the best possible performance on different hardware configurations.
