The Ryzen 7 5800X3D breathed life into the dying AM4 AMD CPUs, but how does it compare to their flagship processor for that generation? In this comparison between Ryzen 7 5800X3D vs Ryzen 9 5900X, we will let you know about their performance difference after testing them across games.

Comparison Table

Architectural Differences

1. Core Count: The Ryzen 9 5900X has 12 cores that total 24 threads, whereas the Ryzen 7 5800X3D has 8 cores and 16 threads, giving the edge to the Ryzen 9 in most multi-threaded workloads.
2. Core Clocks: The clock speeds of the Ryzen 5800X3D are lower than its bigger brother. The processor clocks at 3.4GHz at its base, whereas the Ryzen 9 5900X goes to 3.7GHz. The boosts clocks for Ryzen 7 and Ryzen 9 are 4.5GHz and 4.8GHz, respectively.
3. L3 Cache: The L3 cache on both these processors is pretty plentiful, with the Ryzen 7 having a massive 96MB cache buffer, whereas the Ryzen 9 has a more modest L3 cache of 64MB.
4. TDP: Both the processors have the same rated TDP of 105 watts, though the Ryzen 7 5800X3D chips have a reputation for being highly power efficient. 
5. Processing Nodes: Both these processors are built on the TMSC’s 7nm processing nodes using the Zen 3 architecture. They use the AM4 socket, which has been in use since the first-gen Ryzens.

Gaming Benchmarks At 1080p

To help you better understand the performance differences between these CPUs apart from their specifications, we have put them to the test across 5 games at 1080p.
