Nvidia RTX 5090 to feature PCIe 5.0 and full DisplayPort 2.1a support
Nvidia to deliver next-gen connectivity with their RTX 5090 graphics card
Rumour has it that Nvidia plans to reveal their next-generation RTX 5090 and RTX 5080 GPUs at CES 2025. With the release of these new GPUs, Nvidia will be bringing new features to their GeForce product line. The RTX 5090 will likely be Nvidia’s first GPU to support PCIe 5.0 and DisplayPort 2.1a. Next-gen connectivity for Nvidia’s next-gen GPUs.
Benchlife has claimed that yesterday’s leaked RTX 5090 and RTX 5080 specifications are correct. This gives Nvidia’s RTX 5090 32GB of GDDR7 memory and 21760 CUDA cores. Additionally, this means that the RTX 5080 has 16GB of GDDR7 memory with 10752 CUDA cores. Note that the RTX 5090 has more than two times as many CUDA cores as the RTX 5080.
Regarding DisplayPort 2.1, Nvidia’s next-generation GPUs are due to support this standard with full HBR 20. This will give the RTX 50 series full DisplayPort 2.1a support. Note, that AMD’s current-gen RX 7000 series GPUs are limited to DisplayPort 2.1a with HBR 13.5. This gives these GPUs access to 54 Gbps of connection bandwidth. With HBR 20, Nvidia’s next-gen GPUs will have access to 80 Gbps of bandwidth.
Nvidia’s RTX 5090 will likely be the first GPU to use PCIe 5.0 x16 connections on modern PC motherboards. The GPU is also said to use a 14-layer PCB and feature a single 12V-2×6 power connection (at least for the Founders Edition).
