AMD Ryzen 9 7950X & Ryzen 7 7700X ‘Zen 4’ Review

Cinebench Performance Per £ GBP

Examining the productivity performance value through the guise of Cinebench performance per £, we see the reoccurrence of an old trend for new-versus-old AMD products during launch times.

The current stellar deals for AMD’s Ryzen 5000 processors offer up tough competition to the new Ryzen 7000 chips. But what is different this time is that Intel’s Core i7-12700K proves to be a well-priced thorn in the side of the Ryzen 7 7700X.

The Ryzen 7 7950X offers good productivity value, despite this metric being somewhat unimportant for a flagship product. But the more budget-conscious buyer stumping up for a roughly £400 chip may have a tough time going for the Ryzen 7 7700X when looking purely at this chart.

Cinebench Performance Per Watt

Top of the performance per Watt chart is AMD’s venerable Ryzen 9 5950X but the new Ryzen 9 7950X is not far behind.

This is an interesting point as the new 16-core flagship certainly isn’t friendly when it comes to power draw numbers. But it does deliver outstanding multi-threaded performance from those lofty levels of power consumption, so I guess that’s absolutely fine.

The Ryzen 7 7700X also does reasonably well in terms of efficiency, sitting between its two primary competitors.

The Ryzen 9 5900X delivers more performance for slightly more power and therefore beats the Ryzen 7 7700X’s efficiency score. But the Core i7-12700K delivers its higher level of performance with considerably more power used and therefore cannot match the 7700X’s efficiency.

Cinebench Perf Per Watt inc. Eco Mode

And if we now switch up the performance-per-Watt chart to include numbers when running the Ryzen 7000 chips in reduced power – ECO – modes, we see a very different pattern.

We know that the Zen architecture has always been particularly strong at lower clock speeds and TDP levels; the performance scales very well when frequency and therefore power are reduced.

What is particularly interesting though is the Ryzen 9 7950X at the previous flagship TDP level of 105W or 142W package power. Efficiency here goes through the roof, yet we only see a modest reduction in Cinebench performance. The same point can be made for the Ryzen 7 7700X when running at its 65W TDP or 88W package power mode.

Where the biggest exclamation point is made, though, is with the Ryzen 9 7950X running at 65W TDP or 88W package power mode. AMD really weren’t exaggerating when they said that Zen 4 excels at 65W TDP!
