Faster graphics memory is on the horizon . Samsung is typeset to uncover 37Gbps GDDR7 VRAM , intend the fastest memory of this type that we ’ve seen to date . This progression could impart some serious gains to next - gentop computer graphic posting , especially if it negociate to be feature in Nvidia ’s next - genRTX 50 - series GPUs .
Samsung is holding a seance at the five - day2024 IEEE International Solid - State Circuit Conference , titled “ A 16Gb 37 Gb / s GDDR7 DRAM with PAM3 - optimise TRX Equalization and ZQ Calibration , ” first distinguish byTechRadar . That ’s how we jazz this is encounter , as Samsung has n’t officially announced these libertine computer memory variance yet .

GDDR7 storage is currently a workplace in progress for Samsung , but also for companies like SK Hynix and Micron . We ’ve antecedently get a line of VRAM reach pep pill up to 32Gbps , but now , those speeds are inching much higher with the in style development .
To accomplish these haemorrhage - edge speeds , Samsung is say to utilize PAM3 and NRZ sign . PAM3 encryption will tolerate for high data transmission pace per Hz , ultimately delivering lower power using up while up the memory speed .
VRAM with 37Gbps speeds , once we get there , will mark a important upgrade over what we ’re currently seeing in GDDR6X. For instance , Nvidia ’s RTX 4090provides bandwidth of 1TB / south thanks to its 21Gbps memory across a 384 - bit bus . However , next - gen GDDR7 memory will provide that variety of bandwidth across a 256 - bit user interface when time at 32Gbps .
Samsung ’s late 37Gbps innovation , when geminate with a 384 - bit bus , will interpret to a humongous 1.79TB / s. That ’s nearly double what the RTX 4090 can furnish .
However , it has already announced 32Gbps GDDR7 memory in the summer of 2023 . Samsung is n’t alone in pushing for faster VRAM — SK Hynix is also reportedly fix to denote its own update , with a session titled “ A 35.4Gb / s / PIN number 16 GB GDDR7 with a Low - Power Clocking Architecture and IO Circuitry . ”
This is pretty exciting news for the GPU industriousness , designate us that the future of GPUs will greatly increase bandwidth . However , even though the speculation is that thenext - gen graphics cardsfrom AMD and Nvidia will employ GDDR7 , it ’s unlikely that these firm memory module will be usable by then .
We might see the RTX 50 - serial and AMD RDNA 4 launch with GDDR7 but with lower fastness . They ’ll still be an improvement over current - gen variants , but 37Gbps VRAM may have to wait until the generation after the one that ’s coming next . In other words , we ’ll most in all likelihood see it get in 2026 .
