I've been doing some research on CPUs and I keep seeing X3D mentioned, especially when comparing the 7000 and 9000 series from AMD. I read that they have something called a 3D cache, but I don't quite understand what that means. Could someone explain why it might be better to choose an X3D chip over just upgrading from a 9600X to a 9700X? Also, if you have any YouTubers who cover this topic well, I'd appreciate the recommendations as I'm starting from scratch in learning about tech.

So, the X3D chips have much larger and faster L3 cache, which is a game-changer, especially for memory-heavy tasks. They allow the CPU to pre-cache data, minimizing the need to fetch from slower RAM. In gaming, where data often lays out in larger blocks, this extra cache can really speed things up. However, not all games will benefit from it, especially those that are less dependent on memory access.
Exactly! Plus, since RAM prices are high right now, having an X3D CPU can help you avoid the need for expensive high-speed RAM.
X3D CPUs are fantastic for gaming, but you might not need one if budget is an issue. If stretching for an X3D means cutting back on your GPU budget, just go for the 9600X or 9700X instead. They'll still give you solid performance but won't have the extra cache benefits.
That’s true! Without the X3D cache, you might need to invest in faster RAM to help compensate for the increased latency.
It’s the added memory capacity on the chip itself that makes the X3D so beneficial. With the 3D stacking technology, it allows the CPU to store more information closer to the cores, which drastically improves processing speeds, especially for games that rely heavily on CPU performance.
That’s really insightful, thanks! So it’s not just marketing fluff after all.
Exactly! It’s all about getting more performance for gaming out of the box.
The big deal with X3D CPUs is the cache. Essentially, the cache is where the CPU stores information it needs for calculations. If something isn't in the cache, the CPU has to go to the slower system RAM, which can cause delays in processing—leading to lower frame rates in games. X3D CPUs have triple the L3 cache compared to regular CPUs, which means they can do more calculations without accessing RAM as often, resulting in better performance in gaming.
So, does that mean the latency is significantly reduced compared to non-X3D models?
Exactly! And because the cache is stacked, it’s physically closer to the cores, which helps with speed.
The X3D models are geared especially for gaming since they manage to lower latency with their larger cache. However, if you don't play CPU-bound games, you might not notice much difference, so consider what games you play before splurging on one.
Thanks for that advice! I mostly play casual games, so a regular CPU might be sufficient.
If you play more demanding games, though, those X3D chips can really shine!
That really clarifies things! I see how pre-caching would help in a gaming context.
