GDDR6X consumes 15% less power per transferred bit than GDDR6, but overall power consumption is higher since GDDR6X is faster than GDDR6. On average, PAM4 consumes less power and uses fewer pins than differential signalling while still being faster than NRZ. GDDR6X is thought to be cheaper than High Bandwidth Memory. [25]
The Lovelace architecture can use either GDDR6 or GDDR6X memory. GDDR6X memory features on the desktop GeForce RTX 40 series while the more energy-efficient GDDR6 memory is used on its corresponding mobile versions and on RTX A6000 workstation GPUs.
As of 2025, GDDR SDRAM has been succeeded by GDDR2, GDDR3, GDDR4, GDDR5, GDDR5X, GDDR6, GDDR6X, GDDR6W and GDDR7. Generations Hynix GDDR SDRAM. A Samsung GDDR3 ...
Their primary characteristics are higher clock frequencies for both the DRAM core and I/O interface, which provides greater memory bandwidth for GPUs. As of 2020, there are seven, successive generations of GDDR: GDDR2, GDDR3, GDDR4, GDDR5, GDDR5X, GDDR6 and GDDR6X.
All other cards use GDDR6X video memory manufactured by Micron. RTX 4060 and RTX 4060 Ti have a limited 8 lane PCI Express 4.0 bus interface. All other cards support the full 16 lanes. There is a slower (on average 1% slower according to a single review [17] so far) variant of the RTX 4070 with 20Gbps GDDR6 VRAM introduced in August 2024. All ...

This list contains general information about graphics processing units (GPUs) and video cards from Nvidia, based on official specifications.In addition some Nvidia motherboards come with integrated onboard GPUs.
RDNA 3 GPUs use GDDR6 memory rather than faster GDDR6X due to the latter's increased power consumption. Media engine RDNA 3 is the first RDNA architecture to have a ...
