NVIDIA GeForce RTX 5080 16 GB GPU To Feature Fastest 32 Gbps GDDR7 Memory Speeds & 1 TB/s Bandwidth

NVIDIA's GeForce RTX 5080 GPU will feature the fastest 32 Gbps GDDR7 memory available at the time of its launch.

NVIDIA GeForce RTX 5080 Will Be The First GPU To Utilize 32 Gbps GDDR7 Memory At Launch

NVIDIA's GeForce RTX 5090 & RTX 5080 GPUs are going to be the flagship offerings within the next-gen Blackwell lineup and it looks like the second SKU is going to feature the fastest DRAM solution on the market when it launches.

We have just received word from our sources that the NVIDIA GeForce RTX 5080 GPU which will be utilizing the GB203 GPU core will come equipped with 16 GB of GDDR7 memory which will operate at 32 Gbps speeds. This is 4 Gbps faster than the 28 Gbps dies featured on the GeForce RTX 5090. The graphics card will feature a 256-bit wide bus interface and as such, it should feature 1 TB/s of total bandwidth from the memory alone.

This is going to be a major leap over the RTX 4080 series which peaks out at 736 GB/s of bandwidth through their 23 Gbps GDDR6X solution. The G6X solution is absolutely bonkers but GDDR7 will be the game changer and provide GPUs with higher bandwidth, especially those with a narrow bus. It should be noted that 32 Gbps speeds won't be featured across the entire lineup and only the RTX 5080 would get it at first. The possibility that NVIDIA might upgrade the lineup to faster speeds (G7) and higher capacities exists but for now, let's stick to what we can expect from the initial wave of the cards.

NVIDIA GeForce RTX 5080 Graphics Card

Based on previous information, the NVIDIA GeForce RTX 5080 graphics card will be based on the PG144/147-SKU45 PCB and will incorporate the GB203-400-A1 GPU die. This card will utilize the full GB203 GPU die with 84 SMs and 10,752 cores but that's a big -51% reduction compared to the RTX 5090. For comparison, the RTX 4090 and RTX 4080 had a -40 percent difference in the number
