• Samsung's GDDR7 is set to be showcased in February 2024, with transfer rates up to 37Gbps, while also reducing power consumption.
• Compared to GDDR6 and GDDR6X, GDDR7 is expected to deliver noticeable performance enhancements and use less power.
• GDDR7's widespread availability coincides with the next generation of GPUs from Nvidia and AMD, potentially resolving the issue of limited memory bandwidth in high-performance computing products.

In a high-end GPU, GDDR7 would also mean significant increases to total memory bandwidth. In a theoretical RTX 5090 with a 384-bit memory bus, 37Gbps memory chips would equate to a whopping 1.78TB/s of memory bandwidth. To put that into perspective, that's 78% higher than an RTX 4090, which has 1.0TB/s of memory bandwidth.
Generally speaking, memory bandwidth has been limited on modern high-end graphics cards such as Nvidia's 4000-series, given the dramatic increase in compute power without a commensurate increase in memory bandwidth. With the arrival of the GDDR7 at the end of 2024 or the beginning of 2025, this pain point could finally be resolved leading to greater performance when gaming at high resolutions such as 4K and beyond. GDDR7's release is expected to coincide with the next generation of GPUs from Nvidia and AMD, but exact dates for next-gen GPUs have not yet been determined. When GDDR7 launches, it will most likely be featured in both Nvidia Blackwell (5000-series) and AMD RDNA4 (8000-series).

Samsung's 37Gbps GDDR7 could increase memory bandwidth on next-gen Nvidia and AMD GPUs by 78%

Impressive numbers, memory bandwidth is more important than it's ever been, especially for companies like Nvidia who are making a heavy push into AI, the performance will of course trickle down into dGPU's and consoles as well. I do hope the next PS6 isn't as bandwidth constrained as the PS5 is.

It will be interesting to see performance of 5080, 5070 (5070 Tie as well) and 5060 series with these kinds of bandwidth numbers.

It will release exactly when i upgrade my PC in 2026/27.

Lol, Knowing Nvidia they will rather half the memory bus again.

 

[Celcius]

Will be interesting to see if high end cards stay at 24gb next gen.

get ready for 128bit RTX 5080

I’ll believe it when I see it.
