The World‘s Largest GPUs: Pushing Boundaries of Power

Without a doubt, the current holder of the "world‘s largest GPU" title is NVIDIA‘s flagship GH100 Hopper clocking in at a staggering 1000mm2 die area. Built on an advanced 5nm TSMC process and leveraging NVIDIA‘s new Transformer Engine architecture, Hopper represents the bleeding edge of graphics processing for AI and high performance computing.

Set to launch in 2023 for data centers and supercomputers, Hopper‘s H100 GPU unlocks up to 30 TFLOPS of FP8 performance and touts 60% faster training times for gigantic Transformer models. Backing up the H100, Hopper‘s Grace CPU Superchip integrates Arm CPU cores directly into the package using NVIDIA‘s NVLink interconnect. This CPU-GPU hybrid architecture minimizes latency while maximizing power efficiency.

Simply put, no other GPU comes close today in terms of sheer scale and performance as Hopper‘s H100 graphics processor. By packing over 80 billion transistors onto a single 5nm chip, NVIDIA has created the world‘s largest GPU ever manufactured. It symbolizes the tremendous growth in demand for more advanced GPU compute as AI models continue exploding in size and complexity.

Gaming GPU King – GeForce RTX 4090 Overview

But for gaming enthusiasts and PC builders, there‘s another NVIDIA GPU that holds the crown for largest gaming graphics card: the GeForce RTX 4090. Built using the same radical Ada Lovelace architecture that powers Hopper, the RTX 4090 wields 97.2 billion transistors configured into 16,384 CUDA cores on TSMC‘s 4nm process.

As this specs table illustrates, the 4090 pushes boundaries across the board to deliver up to 2-4X gains over its predecessors. The 16GB and 20GB models of NVIDIA‘s previous generation RTX 3090 already seemed excessive for most gamers, but Ada Lovelace doubles down with 24GB of 21Gbps GDDR6X RAM.

The reasons behind this embrace of maximalism tie back to NVIDIA‘s own research showing games demand more memory bandwidth every year. 2020‘s titles utilized ~6GB on average while cutting-edge 2023 games tap over 10GB typically. With the next generation of games promising photorealistic graphics through real-time raytracing coupled with deep learning super sampling (DLSS), equiping your GPU with ample VRAM headroom is critical even for leading edge cards today. That‘s why NVIDIA chose to make the GeForce RTX 4090 it‘s new halo product delivering no compromise, max settings 4K gaming.

Pushing VRAM Limits Over Time

Looking back over the history of graphics cards shows the steady march upwards in video memory capacities as gaming workloads evolved:

Where we go from here remains excitingly unclear. With GPU architectural innovations happening faster than Moore‘s Law, I expect capacities to scale beyond 24GB in the coming years. My predictions put a 32-64GB RTX 5090 possible by 2025, enabled by shrinks to transistors below 4nm and advanced memory technology.

In closing, today‘s GPU size kings consist primarily of NVIDIA data center offerings designed specifically for massively parallel workloads like training AI models. But for us gamers, the incredible RTX 4090 and its 24GB framebuffer establishes itself as the new gold standard for bleeding edge PC gaming. I‘m thrilled to see what boundaries NVIDIA pushes next as it continues marching down the path to creating the world‘s most powerful graphics cards ever!
