Choose an upgrade, lateral adjustment, or downgrade: 5900X to 5800X3D
I’m considering upgrading from a B550i with a 5900X to a 5800X3D. With the current setup running at 4K and mostly gaming, it feels like a good opportunity to refresh your hardware. You could get the new graphics card for around $350 and sell the older one for at least $250, making the change a relatively affordable move. My goal is to breathe new life into my AM4 system and add another CPU/RAM upgrade in the next couple of years.
It would be a minor improvement. For gaming, it offers roughly a 15-20% boost in most games at best, but may slightly reduce performance in some titles that rely more on clock speed than cache (such as CS:GO). In productivity, it represents a significant drop (20-30%) across the board, except for a few tasks that gain more from cache than clockspeed and cores (like certain compilation jobs).
The side downgrade mainly affects demanding titles; GPU limitations remain strong even at 4K on a 4090. Those without high FPS won’t really feel the impact, and losing 33% of cores while clocking 15% slower slows performance across all tasks—not just games. In games, the improvement will be minimal, as shown by these benchmarks (using a 5950X, results similar with a 5900X).
In 4K settings performance remains strong. Demanding 4090 still meets expectations. Productivity gains won’t match 5800x3D. Overall it’s a step back.
For gaming purposes only, the 5800x3D is the only upgrade, while all other models are inferior. The 5900x causes bottlenecks with the 4090.
5800x3d offers unique value for gaming and cache-intensive tasks, but it can hit limits when paired with high-end GPUs. In such cases, its performance may plateau while downsides become noticeable. For better results, adding more cores or higher clock speeds often improves efficiency. Overclocking is possible but constrained by BIOS limits—typically around 114 MHz or less—and might require upgrading to PCIe 2.0 or similar. The issue with BCLK is that it only boosts clock speed without addressing other bottlenecks, which can lead to frustrating performance caps. Storage issues remain unconfirmed, so it’s likely just a temporary fix.
I notice many gamers running 7000 series or 13th gen Intel models achieving impressive results even at 4K resolution. A lot of top-tier games run smoothly on a 4090 with moderate CPU usage. Port Royal, for example, can be about 10-12% faster. I’m planning to upgrade to something like the 8700x3d or 8900x once it’s released. I’ve reached my annual upgrade goal.
5900X wide open packs a powerful punch. It’s incredibly quick as well. My setup can hit the full 5150 across many cores. It delivers raw energy and strong performance. But honestly, it’s just as fast as it gets. X3D makes cooling a breeze since you’re essentially turning your high-end rig into something like a Dell. If you’re someone who mainly plays games, watches shows, shops online, and still gets the speed you need, X3D works perfectly for you.
Thanks for the responses. This decision is fully focused on gaming. Outside of that, I mainly use the computer for office work and browsing the web. I think the 5900X would be more suitable for productivity, but I’m mostly into games or tasks that fit a Chromebook.
