According to my leak looks like AMD has gone Intel’s way when it comes to overclocking their processors. Clocking is no longer only about 50-200 MHz with All-Core settings, but according to the leak, the new Ryzen 9000 processors can be clocked and scaled in performance with power limits very nicely.
The graph shows the Ryzen 9 9950X in unlimited PPT mode with a consumption of 320W.
An Anandtech forum user used unspecified water cooling to cool the Ryzen 9 9950X processor. From the numbers, it can be concluded that it will be cooling of a more solid nature. He certainly didn’t use an AIO, first it will be an open circuit with high thermal capacity and above average heat dissipation (lots of radiators, lots of fans, maybe radiators located in the basement, etc.). Simply, you probably won’t try it at home.
The clocks achieved were as follows at different power:
- Ryzen 9 9950X (unlimited PPT – Package Power Tracking – CPU consumption) – max. achieved clock rate 5621 MHz / max. temperature 80°C
- Ryzen 9 9950X (253W PPT / 5.5 GHz OC) – max. achieved clock speed of 5500 MHz / max. temperature 61°C
- Ryzen 9 9950X (230W PPT) – max. achieved clock rate of 5620 MHz / max. temperature 62°C
- Ryzen 9 9950X (160W PPT) – max. achieved clock rate of 5555 MHz / max. temperature 58°C
- Ryzen 9 9950X (120W PPT) – max. achieved clock speed of 5220 MHz / max. temperature 55°C
- Ryzen 9 9950X (90W PPT) – max. achieved clock speed of 5050 MHz / max. temperature 49°C
- Ryzen 9 9950X (60W PPT) – max. achieved clock rate 4084 MHz / max. temperature 41°C
Graf from wcftech.com shows it:
From the table we can see that clocks on 16 cores are really respectable at every wattage setting of the new CPU. And having 5200 MHz at 120W is really not to be thrown away, since the base clock is almost 1GHz lower (~900 MHz).
In comparison, the Intel 12900K, KS, 13900K, KS and 14900K and KS need 250W to reach a stable 4.6 GHz across all 8 P-Cores without deeper settings. When limiting PL1 to 150W and PL2 to 170W, the P-Cores reach clocks between 4.3 – 4.5 GHz. These are just my amateur numbers, there are no sophisticated settings involved, just lowering the PL (Power Limit) in the board’s BIOS/UEFI.
Another interesting piece of news is that the tested piece is a so-called ES (Engineering Sample), and thus it is an engineering sample – a non-final piece. This means that the final CPUs can behave either the same or maybe even better. Also noteworthy is that the given chip only needs 160W to beat the Intel Core i9-14900K with power locked at 200W.
By the way, the tester used Blender Benchmark to test the stability of the clocks of the given CPU. For more information you can see thread on anandtech.
The image shows the Ryzen 9 9950X in 253W PPT mode, where it is set to the same power limit as the Intel Core i9-14900K in PL2 (Power Limit 2 – shorter Turbo Boost 3.0 time window and power).
All this overclocking is nice, but what does it mean for the average gamer? It should mean that AMD’s new processors will need cheaper cooling, they should be more stable and achieve naturally higher clocks and more performance with lower consumption, and overall they will be closer to Intel in terms of overclockability and possibly software stability.
