SemiAnalysis has been on a five-month long quest to settle the reality of MI300X. In theory, the MI300X should be at a huge advantage over Nvidia’s H100 and H200 in terms of specifications and Total Cost of Ownership (TCO). However, the reality is that the on paper specs as given below are not representative of performance that can be expected in a real-world environment. If AMD could deliver the below marketed performance with this memory, it would be a very strong competitor in the market. 

Today we are going to talk through our five-month journey conducting independent analysis and training-focused benchmarking of the MI300X, the H100 and the H200, engaging with both NVIDIA and AMD. We will do a detailed overview of the numerous low-level benchmarks that we ran, see the table of contents for summary. Furthermore, we will compare the total cost of ownership of Nvidia and AMD GPUs and factor in performance. Ultimately much of what we are doing is openly giving a comprehensive public recommendation to AMD on what they need to do to be competitive and fix their software issues after five months of submitting and squashing bugs. It’s not just that it’s immature software, they need to change how they do development. 

In short, when comparing Nvidia’s GPUs to AMD’s MI300X, we found that the potential on paper advantage of the MI300X was not realized due to a lack within AMD public release software stack and the lack of testing from AMD.
