Blender Classroom

Looking at Blender Classroom rendering performance, the new Ryzen 9 7950X takes a commanding lead at the top of our chart. The next best processors – AMD’s 16-core Ryzen 9 5950X and Intel’s Core i9-12900K – are way behind in this multi-threaded rendering test.

The Ryzen 7 7700X is far less impressive though, with a performance showing that is reasonable, but is slower than its Core i7-12700K and Ryzen 9 5900X competitors. Yes, both of those chips have higher thread counts than AMD’s new 8-core. But they’re positioned at similar price points, too.

Cinebench R23 nT

Cinebench R23 nT shows much of the same trend as Blender. The new Ryzen 9 7590X is an absolute performance monster thanks to its 32 threads pumping away at lofty clock speeds.

But those same Zen 4 clock speed benefits cannot help the Ryzen 7 7700X overcome its thread count deficit versus its realistic price competitors – the 12700K and Ryzen 9 5900X.

As a side note, we checked performance and clock speed sustainability with 10 minutes of Cinebench R23 back-to-back runs, but none of the processors on show today had significant performance drop offs via boost clock speed reductions. So, that’s positive to report.

Cinebench R23 1T

Single-thread performance is superb on the new Ryzen 7000 series chips. The flagship 7950X boosts as high as 5.7GHz and therefore delivers chart-topping performance that is above the speedy Core i9-12900K. And the 5.55GHz peak of AMD’s Ryzen 7 7700X in our testing positions it at third place in our chart – beating its Core i7-12700K competitor and smashing the Ryzen 9 5900X.

The performance uplifts for Zen 4 versus Zen 3 in a single-threaded domain are outstanding.
