Looking for guidance on benchmarks or someone who knows real-world experience?
I find myself in an unusual situation. My system runs a Ryzen 9 3900X, and I’m considering upgrading to either the R9 5950X or the R7 5800X3D. I really want that noticeable improvement in frames per second from the 5800X3D, but I also don’t want my performance to drop compared to what I have now for tasks like Blender work. The benchmarks I’ve seen focus mainly on CPU-based rendering, which isn’t really relevant since I rely more on GPU power. I’m curious about how the viewport and physics features in Blender perform under load—there aren’t many clear tests for that. Some simulations I run require 20GB to 50GB of RAM, so it’s a memory-heavy process. I’m wondering if the extra cache on the 5800X3D would really help, especially given the heavy data handling, or if the bigger CPU capacity on the 5950X would just handle it faster. Since I don’t do these kinds of tasks often, even a slight drop wouldn’t be a big deal. But I’m also thinking about memory usage more generally—single CCD Ryzens seem slower than double CCDs, so that could affect things too. I’m not planning to buy right away, but I’m leaning toward moving up to a higher tier on AM4 eventually, rather than sticking with AM5 or LGA1700 when these chips hit the second-hand market. For now, I’m just trying to understand better.
Aim for 5950X in games only after reaching high frame rates. It’s better to stick with it and boost graphics instead. For longevity, remember that CPUs like 5600, 12100F, and 12400F were common this generation. 5950X is quicker than all of them, so developers wouldn’t want to leave most players behind when making new games.
Even with the 5950x being 2ccd, you still retain a 64mb cache, which could contribute to some performance improvements.
I already have games running at 1440p that demand heavy CPU processing, even when using 3060ti. I play on medium to high settings to maintain a good frame rate. Yes, upgrading to 5800X3d or 5950X would be better than 3900X for gaming, though it's unclear if it's an improvement or a decline in performance for my current setup. I'm not too concerned about long-term changes since most systems are shifting toward GPU-based tasks. There is some slowdown from CCD crosstalk, but the extra L3 memory doesn't significantly affect things if data constantly moves between CCDs, unlike with 5800X3d where everything stays in one large pool. I'd really appreciate exact figures for this comparison.
I assure you there would be no more than a 10fps gap between the R7 5800X3D and the 5950X. For your tasks, choose the 5950X; for gaming it’s a significant improvement over your current CPU, and you’d maintain similar frame rates to the 5800X3D. To notice a difference, you’d need a 3090 or a more powerful card, and you’d likely play mostly at 1080p since the gap at 1440p with a 3090 isn’t substantial.
I'm discussing titles where performance stays in the 70-90 FPS range because I'm CPU constrained rather than aiming for higher numbers. I use GSync at 165Hz with a fixed 160 FPS target. I don't prioritize exceeding the refresh rate, but I still want better frame rates since staying below 100 feels insufficient, particularly when consistency is lacking. This subject isn't really about gaming.
The 5950x performs well in gaming as well. It reaches 5ghz, whereas the 5800x3d operates around 4.5ghz, helping it regain some frames per second. However, certain games—especially single-threaded physics simulations—benefit from the 5800x3d's larger cache capacity, making it quicker in those cases.
