AMD Ryzen 7 7800X3D Review – We Told You To Wait!

Rating: 9.0.

When we reviewed the recent 16-core AMD Ryzen 9 7950X3D CPU we loved it to pieces, however we told you to wait until we got our hands on the Ryzen 7 7800X3D. We were confident the 8-core 3D Zen 4 would be good and we knew it would be cheaper than Ryzen 9, and now you're going to find out whether we were correct.

Understanding the basics about the new AMD Ryzen 7 7800X3D is nice and straightforward. AMD has taken a Zen 4 Ryzen 7 7700X with its IO die and 8-core chiplet, added a slab of 3D cache on top of the chiplet, adjusted the clock speed and power limit downwards and then increased the price. We have seen in our reviews of the Ryzen 7 5800X3D and Ryzen 9 7950X3D that the extra L3 cache  yields dramatic benefits in gaming.

Unlike the Ryzen 9 7950X3D and Ryzen 9 7900X3D which each have two chiplets (one with 3D cache and one without) there is no need for any funny business with the chipset drivers to help the system to figure out which chiplet should be used to process a particular task. Having said that, you can see in our screen grabs that the chipset drivers are doing a fair amount of work behind the scenes.
