Unveiling the Future of GPUs: GDDR7 Memory Emerges

In a recent financial report for the third quarter of 2023, Micron, a important player in memory technology, offered a glimpse into its ongoing pursuits in the realm of memory products. A highlight of their disclosure was a tantalizing sneak peek into the impending arrival of GDDR7 memory – an innovation set to reshape the landscape of graphics performance. This new entrant is slated to make its debut in the first half of 2024.

At the core of the GDDR7 buzz lies the technological underpinning. Micron has opted for the robust framework of the 1ß process node for this upcoming memory advancement. This is a precursor to the forthcoming 1γ process node in 2025, a transformational milestone in memory fabrication. The initial deployment will occur at Micron’s Taiwan facility, leveraging their pre-existing EUV (Extreme Ultraviolet Lithography) capabilities, followed by integration at their Hiroshima, Japan fabrication site.

Imagine a memory paradigm shift with GDDR7 making its entrance, eclipsing the capabilities of both GDDR6 and GDDR6X. This is akin to trading in your traditional bicycle for a high-speed motorbike. The driving force behind this advancement is PAM3 Signaling, a technical term denoting expedited data transfer rates. How fast are we talking? The bar has been set at an impressive 36 Gbps. To contextualize this speed, consider that the existing frontrunners, nVidia’s Geforce RTX 40 series, peak at 22 Gbps, while AMD’s Radeon RX 7000 series employs GDDR6, achieving a standard 20 Gbps.

Delving deeper, Samsung’s ambitions encompass the concurrent development of GDDR6W and GDDR7 solutions. The result? A twofold increase in both capacity and performance. Parallelly, Micron is on a trajectory to elevate GDDR6X speeds even further, akin to infusing a high-performance engine with an additional turbocharger. Micron has been busy manufacturing 24 Gbps components, but their integration into consumer-grade GPUs awaits its moment.

As we cast our gaze towards the horizon, the release of NVIDIA’s Ada Lovelace-Next GPUs looms on the horizon, anticipated to materialize in 2025. The race to harness the power of GDDR7 appears to tilt in favor of AMD as the front-runner. However, NVIDIA’s strategic alliance with Micron in critical domains such as AI and Datacenter remains formidable, with NVIDIA contributing HBM3 chips for the DGX GH200 supercluster and the broader Hopper series. The allure of GDDR7 lies in its transformative memory bandwidth enhancement, though it does come at a cost premium compared to the existing GDDR6 and GDDR6X alternatives. As the curtain rises on a new era of Graphics Cards, the promise of enhanced capabilities is matched by the considerations of investment.
