Upcoming RTX 3090 Ti GPU Tipped To Feature 21 Gbps GDDR6X memory from Micron

Like all the other tech giants, NVIDIA is ready to make a splash at CES 2020. The company is ready to announce a slew of new RTX 30-series graphic cards along with an updated 12GB model of the RTX 2060. Among the expected announcements is the reveal of a brand new flagship, the RTX 3090 Ti. As the name suggests, this is a slightly upgraded model of the current top-dog RTX 3090 with even more power packed in. And, today, the exact memory specification for this beast finally leaked out.

Thanks to Taiwanese media outlet, Uniko’s Hardware, we now know that “MT61K512M32KPA-21U” memory is to be used in the RTX 3090 Ti. That’s a codename from the list of unreleased Micron products which confirms that is the precisely the memory NVIDIA is putting inside their next flagship. It also allows us to tally that codename from Micron’s catalogue, and that’s exactly what Videocardz has done, giving us even more juicy info in return.

Micron GDDR6X

MT61K512M32KPA-21U is a GDDR6X memory solution from Micron running at clock speed of 21Gbps. That’s about 1.5Gbps faster than the RTX 3090‘s memory. The RTX 3090 Ti will still feature 24 GB of total VRAM but, as this codename confirms, it will be slightly faster. On top of that, RTX 3090 Ti will also mark the debut of 2GB GDDR6X memory modules inside a GeForce card for NVIDIA.

Before this, 2GB memory modules for GDDR6X did not exist so NVIDIA relied on 1GB (8Gb) modules to power all of their RTX 30-series GPUs, including the RTX 3090 which needed 24 modules as a result of this. Now, with the advent of 2GB (16Gb) modules, NVIDIA will need to use only 12 GDDR6X modules to fuel the 24GB VRAM of the RTX 3090 Ti.

Less memory modules aren’t just a excuse for innovation, they actually can allude to overall betterment for your card as there is less active cooling needed to keep the memory in control. And, if you know anything about GDDR6X memory inside RTX 30-series graphic cards, you’d know how crucial that is. RTX 3090 already adapts a half and half approach where it has half of its memory modules located on the backside which makes it so that the backplate also requires active cooling. Therefore, only 12 memory modules would likely negate the need for this.

That being said, the RTX 3090 Ti is said to have a thermal output of 450W which is a full 100W over the TDP of the RTX 3090, so you can bet that it will still need all the cooling in the world, and then some. Apart from that monstrous TDP, RTX 3090 Ti will also be the first GA-102-based graphic cards to utilize the full GPU. That allows it to carry 10,752 CUDA cores. And, while it still has the same amount of VRAM and the same 384-bit memory bus as the RTX 3090, the slighly higher memory clock gives it enough leverage to break the 1TB/s memory bandwidth barrier.
