GDDR7 memory will be one of the most important innovations we will see in the next generations of NVIDIA and AMD graphics cards, and according to the latest information, it will be integrated into the GeForce RTX 50 and the Radeon RX 8000, two lines that, if all goes according to plan, will come to market between late 2024 and early 2025.

The data I gave you is an estimate, but it has a solid basis, because normally NVIDIA and AMD keep each generation on the market for two yearsso it would be normal for the successors to the GeForce RTX 40 and Radeon RX 7000, which launched in 2022, to arrive in that timeframe.

The use of GDDR7 memory will allow significantly increase bandwidth of this new generation of graphics cards and without the need to use wider memory buses. In case anyone is lost, I’ll explain it simply, GDDR6 memories have reached a maximum speed of 20 GHz (20 Gbps bandwidth), while GDDR7 memories will reach 36 GHz (36 Gbps bandwidth).

For example, a graphics card with 20GHz GDDR6 memory and a 384-bit bus would have a bandwidth of 960 GB/swhile a graphics card with 36 GHz GDDR7 memory and a 256-bit bus would achieve 1.15 TB/s, that is, it would have more bandwidth, despite having a lower memory bus. If we use GDDR7 at 36 GHz and a 384-bit bus, the total bandwidth would be 1.7 TB/s.

It is possible that both NVIDIA and AMD will choose it limit the use of this type of memory to your most powerful graphics cards, something that would make sense especially for cost-cutting purposes on mid-range models where price-performance is more important and bandwidth isn’t as important since they’re designed for lower-resolution gaming.

The bandwidth is the determining factor of performance that a graphics card can offer, so it can be expected that the jump in GDDR7 memory will allow for a significant jump in raw performance that will ultimately benefit both gamers and those who use their equipment to work with demanding applications. which are heavily dependent on VRAM.
