Micron's Blazingly Fast 24 Gbps GDDR6X Memory Enters Mass Production, Coming To A Next-Gen NVIDIA GPUs Soon! 1
Written by admin

Well, it seems there are microns officially begins Mass production of its next-generation GDDR6X memory chips that offer speeds of up to 24 Gbps.

Micron’s 24 Gbps GDDR6X memory enters mass production, coming to NVIDIA’s next-gen GPUs later this year

Micron announcement Earlier this year they are preparing their brand new 24 Gbps GDDR6X memory modules for future graphics cards. The announcement comes at a time when NVIDIA’s GeForce RTX 3090 Ti has just entered the market for which Micron has developed a 16 Gb DRAM module rated at 21 Gbps speeds.

Now, Micron is going to offer even faster pin speeds of 24 Gbps at a 16 Gb density which means again, we’ll see 2 GB of VRAM capacity and up to 24 GB of capacity across a 384-bit bus interface. Just like the GeForce RTX 3090 Ti which featured all of its memory modules on the front of the PCB, The next generation GeForce RTX 4090 It will have 12 GDDR6X modules on the front, allowing for more cooling compared to solutions that feature memory modules on the back of the PCB, such as the RTX 3090 (Non-Ti).

While the full 24 Gbps speed is not expected to be used by the NVIDIA GeForce RTX 4090 (rumored to offer up to 21 Gbps die speed), 24 Gbps GDDR6X memory modules can offer up to 1,152 TB/s of bandwidth compared to a current 21 Gbps GDDR6 memory module. 14% increase vs. recommended 1,008 TB/s.

Below are the bandwidth numbers you can expect with a 24 Gbps DRAM solution:

  • 512-bit solution – 1.5TB/s
  • 384-bit solution – 1.1TB/s
  • 320-bit solution – 960GB/s
  • 256-bit solution – 768GB/s
  • 192-bit solution – 576GB/s
  • 128-bit solution – 384GB/s
  • 92-bit solution – 276GB/s
  • 64-bit solution – 192GB/s

The NVIDIA GeForce RTX 4090 is set to be one of the first next-gen graphics cards to use the latest GDDR6X memory modules when it launches later this year. Given that these chips are likely going to be downclocked to hit power targets, there will be a huge overclocking potential for enthusiasts to take advantage of.

AMD, on the other hand, can rely on its partner, Samsung, for its next-generation RDNA 3 lineup. There is also Samsung Working on a 24 Gbps GDDR6 memory module Which is expected to hit mass production soon.
