AMD AI GPU Technology: How it's Staying Competitive

Artificial intelligence is at the forefront of PC hardware and innovations this year. One of the key players in this has been AMD’s MI300X AI GPU. This HPC graphics card has been fine-tuned to dominate in demanding applications, harnessing powerful integrated AI to deliver next-level performance.

But how does the MI300X compare to other AI GPUs? Has AMD done enough to revolutionise and stay ahead of its competitors? We’ll be taking a deep dive into the AMD MI300X AI GPU, showcasing the key features of this exceptional graphics card and how it compares to the NVIDIA H100.

What is the MI300X AI GPU?

The MI300X AI GPU is the latest graphics card to enter the AMD professional line-up. Designed as a competitor to NVIDIA’s powerful H100, the MI300X utilises innovative CDNA 3.0 architecture, 19456 cores, and AMD Instinct MI300A APU accelerator to power all intensive workloads like never before.

The Instinct MI300A is the world’s very first APU that has been fine-tuned for AI and demanding HPC (high-performance computing) workloads. This APU combines a CPU, GPU, and high-bandwidth HBM3 memory into one card to notably boost performance and capabilities. Powering your cutting-edge AI servers or creating them becomes a breeze, especially with eight stacks of HBM3 memory delivering a max bandwidth of 5.3TB/s.

How Does the AMD AI GPU Compare to NVIDIA?

Both the AMD MI300X and NVIDIA H100 have been fine-tuned for heavy-duty workloads. The MI300X combines a multi-core processor, GPU, and HBM3 memory to dominate in any application, whilst the NVIDIA H100 is heavily focused on deep-learning and AI. However, neither card has been optimised for gaming. Both have been designed to not have any connected monitors and don’t include support for DirectX 12 or any GPU shaders.

Ultimately, the MI300X and H100 shouldn’t be used to render the latest games, so we won’t be comparing their performance for gaming. Instead, we’ll take a closer look at some of the differences between these two HPC graphics cards, which you can see in the table below.

	Architecture	Process Type	Process Size	Shader Units	Memory	Memory-Bus	Base Clock	Boost Clock	TDP	Recommended PSU
AMD MI300X	CDNA 3	TSMC	5nm	19456	192GB HBM3	8192-bit	1000MHz	2100MHz	750W	1150W
NVIDIA H100	Hopper	TSMC	5nm	16896	80GB HBM3	5120-bit	1590MHz	1980MHz	700W	1100W

Both these graphics cards have been engineered with a dedicated HPC GPU architecture, 5nm process, and feature plenty of premium HBM3 memory to ensure they can efficiently handle all your multi-threaded applications.

The MI300X excels in clock speeds, capable of achieving a hefty 2100MHz to deliver maximum performance across all your heavy-duty workloads. However, these clock speeds come with the price of a higher TDP and PSU requirement compared to the NVIDIA H100.

No matter their differences, both the MI300X and H100 are the ultimate HPC powerhouses. These graphics cards are designed to handle demanding applications and AI processes with ease. Your key deciding factor between the two is whether you want to reap the benefit of a higher clock speed or lower TDP.
