Chip detective @FritzchensFritz has posted an excellent image comparison between the Ryzen 5 7600 and a Ryzen 7 7800X3D featuring shots taken with an infrared camera. The infrared images show us the inner layers of AMD's Ryzen 7000 and 7000X3D processors, revealing the subtle architectural differences between the different chips.

The differences between both CPUs can be difficult to detect at first glance, but once you know what to look for, the differences are obvious. The left CPU in the image represents the Ryzen 5 7600 (and Ryzen 7 7700), while the right represents the Ryzen 7 7800X3D.

For a refresher on AMD's latest 3D-VCache technology, be sure to check out our previous coverage here. But essentially, the Ryzen 7 7800X3D, Ryzen 9 7900X3D, and 7950X3D feature AMD's 2nd generation 3D-VCache technology, offering significantly faster and denser vertically stacked cache compared to its predecessor.

AMD's 3D cache design helps improve gaming performance and other cache-sensitive workloads by tripling the amount of cache the CPU has access to. This reduces the amount of time the CPU needs to access slower system RAM and keeps more data confined to the faster L3 cache, which improves performance and reduces latency.

    If the 3d cache is 100% between the cores, it seems to me that the solution for the cooling requirements would be to step the heat spreader so that it is closer to the cores and thinner over the cache area. Less of the low performance TIM and more of the higher performance metal over the cores, and the cache is closer to the cooling all around.
