Blender Classroom

Looking at Blender Classroom, the stock Ryzen 9 7900 is well behind the 7900X thanks to its 750MHz frequency deficit. The 65W chip sits between a power unlimited Core i5-13600K and a Core i9-12900K.

Precision Boost Overdrive sees both of those Intel chips blasted past, though, with the 7900 and its 5.05GHz frequency effectively matching a stock 7900X.

For the Ryzen 7 7700, it is noticeably behind the 7700X at stock, and even PBO cannot fully make up the deficit. AMD’s new 65W chip is much quicker than the six-core Ryzen 5, though.

Cinebench R23 nT

Cinebench multi-threaded testing sees a similar trend to Blender.

The Ryzen 9 7900 is comparable to a power unlimited Core i5-13600K but pushes close to the quick 7900X when overclocked via PBO. And the Ryzen 7 7700 is still well above the Zen 4 six-core and Zen 3 eight-core.

Cinebench R23 1T

Single-threaded performance isn’t quite as strong on these 65W TDP parts when compared to the other Zen 4 processors. Lower maximum boost clock frequencies for our test system are the cause here.

Intel’s high-power 13^th Gen competitors are also very strong when it comes to single-threaded grunt.
