NVIDIA enjoys near-absolute supremacy within the PC gaming market. AMD hasn’t made any progress because the underwhelming launch of the RDNA 3 lineup. If latest rumors are to be believed, Staff Radeon has deserted the fanatic market solely, leaving the long run GeForce RTX 5090 and 5080 rivalless. Talking of the RTX 5090, NVIDIA has allegedly began testing Samsung’s GDDR7 graphics reminiscence for its next-gen (gaming) choices.
Wanting on the specs sheet, GDDR7 reminiscence is as much as 40% sooner than present GDDR6X modules whereas lowering energy consumption by 20%. That is achieved utilizing PAM3 modulation, down from PAM4 on GDDR6X. In comparison with the leap from GDDR5 to GDDR6, this can be a milder improve, boosting the obtainable states from 2 to three (50% larger than GDDR6).
| GDDR7 | GDDR6X | |
| B/W Per Pin | 32 Gbps | 24 Gbps |
| Chip Density | 16 Gb/2GB | 16 Gb/2GB |
| Peak Bandwidth (384-bit bus) | 1.5 TB/s | 1.1 TB/s |
| DRAM Voltage | 1.2 V | 1.35 V |
| Information Charge | GDR | GDR |
| Signaling | PAM3 | PAM4 |
Like GDDR6 and GDDR6X, GDDR7 additionally options quad-rate reminiscence bursts, though in comparison with the latter, the signaling is a downgrade. It makes up for this by providing a peak bandwidth of 1.5 TB/s over a 384-bit bus versus 1.1 TB on GDDR6 and GDDR6X.
Our GDDR7 DRAM will assist elevate consumer experiences in areas that require excellent graphics efficiency, comparable to workstations, PCs and recreation consoles, and is predicted to broaden into future purposes comparable to AI, high-performance computing (HPC) and automotive autos. The following-generation graphics DRAM can be dropped at market according to business demand and we plan on persevering with our management within the area.

Sadly, absolutely the energy consumption of GDDR7 can be larger than GDDR6, with a 6-7% enhance for 32Gbps modules (versus GDDR6 24Gbps). The chip density can also be unchanged at 16 or 2GB, no less than on the launch time. Regardless, GDDR7 needs to be successful amongst GPU makers on account of its excessive reminiscence throughput.
NVIDIA’s RTX 50 sequence GPUs are slated to land within the second half of 2024 or early 2025. Leveraging TSMC’s 3nm course of node, they’ll supply the following main leap in rendering efficiency. The chips stay monolithic, with larger density and a bigger floor space. The RTX 5090 ought to characteristic 24-32GB of GDDR7 reminiscence paired with a 384-bit bus.
Theoretically, this is able to ship a bandwidth of 1.5 TB/s and an efficient bandwidth of over 2 TB/s courtesy of the L2 cache buffer. That mentioned, don’t maintain your breath. We’re nonetheless fairly a methods from the Blackwell launch, and issues might change by then.
