Nvidia’s latest RTX 50 series graphics cards come equipped with GDDR7 memory, the latest standard for VRAM designed for AI, gaming, and GPU-accelerated computing tasks. First introduced by Samsung in 2022 to replace GDDR6X, production began in mid-2023 with Micron showcasing its 1β node DRAM process node. GDDR7 offers double the performance of GDDR6X with speeds reaching 32Gbps.
While Nvidia is currently the only company utilizing GDDR7 in its graphics cards, AMD and Intel are still using GDDR6 for their latest models. GDDR7 offers higher bandwidth and faster data transfers, leading to improved gaming and productivity performance.
The RTX 5090 and RTX 5080 are among the first Nvidia GPUs to feature GDDR7, offering 32GB and 16GB respectively. The RTX 5090 boasts 28Gbps effective memory speed and a 512-bit memory bus, resulting in a total bandwidth of 1.79TB/s.
Although GDDR7 shows promising performance gains compared to GDDR6X, the difference may not be as significant in entry-level models. However, as the new standard becomes more widely adopted and developed, performance gaps are expected to widen.
With GDDR7 only being introduced in 2024, it is likely to remain the standard for graphics cards throughout the rest of the 2020s and potentially into the early 2030s. Nvidia is expected to utilize GDDR7 for its next two to three graphics card generations, while the adoption by AMD and Intel remains uncertain.
