Ryzen 7 9800x3D vs Ryzen 7 7800x3D: +8% Performance and $30 more

Recently, AMD launched the flagship CPU Ryzen 7 9800X3D, so if you want to know how it compares to the previous Ryzen 7 7800X3D, we’re going to highlight all the specs and differences between them.

AMD claims that the new Ryzen 7 9800X3D has 8% higher gaming performance, is 15% more profficient in multi-threading apps compared to the older Ryzen 7 7800X3D CPU. However, it’s only $30 more expensive, available at $480 on Amazon. We also have full reviews on Ryzen 7 7800X3D and Ryzen 7 9800X3D if you want to learn more about the CPUs.

Ryzen 7 9800x3D vs Ryzen 7 7800x3D comparison

1. Technical specifications

As usual, we will start by showing the technical specifications of both CPUs side by side, just to have a quick view at the differences between the two:

2. Key differences between Ryzen 7 9800x3D and Ryzen 7 7800x3D

Zen 5 vs Zen 4 architecture

Obviously, the most important difference between Ryzen 7 9800x3D and Ryzen 7 7800x3D is that the latest CPU is designed with Zen 5 architecture on 4 nm while the older CPU is built on the Zen 4 architecture (5nm and 4nm)

According to AMD, Improvements include Improved branch prediction accuracy and latency; higher throughput with wider pipelines and vectors; and deeper window size across design for more parallelism. As a result, single-threaded IPC is increased by about ~16% gen-over-gen.

Base and boost clock speeds

Also, the Ryzen 7 9800X3D CPU offers higher base and boost clock speeds, which translates to better overall performance, especially in gaming. However, both chips comes with the 3D V-Cache technology with a whooping 96 MB of L3 cache that really mages a huge difference when compared to the latest Intel CPUs.

Memory speed

Another notable difference, while not decisive, is that Ryzen 7 9800X3D can work with faster DDR5 memory (DDR5-5600 vs DDR5-5200), which, obviously, translates into higher performance in memory-intensive applications.

Power consumption

When comparing the power consumption, during intensive tasks like the Cinebench multi-core tests, AMD Ryzen 7 9800X3D consumes around 128W higher than the Ryzen 7 7800X3D. In contrast, the 7800X3D has a TDP of 120W but typically operates closer to 88W during normal use. So, Ryzen 7 7800X3D is more power efficient, while Ryzen 7 9800X3D delivers higher performance.

3. Gaming performance comparison

When comparing the gaming performance of the AMD Ryzen 7 9800X3D and the Ryzen 7 7800X3D, the 9800X3D clearly offers better FPS due to its higher clock speeds and improved architecture.

AMD Ryzen 7 9800X3D typically provides around 4-6 FPS more on average compared to the 7800X3D. It also improves minimum FPS by about 6 FPS, which helps in maintaining smoother gameplay, especially in demanding titles.

However, both CPUs proved to be a lot better for gaming than the latest Intel Core CPUs.

Conclusion

Obviously, Ryzen 7 9800x3D tops Ryzen 7 7800x3D in gaming performance and it is only $30 more expensive than the older model. On the other hand, Ryzen 7 7800x3D’s price has risen together with its growing popularity and that might also happen with the new Ryzen 7 9800x3D. So, if you if you want to build a gaming rig now, you should definitely grab Ryzen 7 9800x3D while you can still find it on the shelves.

On the other hand, AMD is expected to launch the new dual-CCD X3D chips soon which the company advertises with higher specs and performance. Decisions, decisions…
