AMD Ryzen 9 9900X 12-Core and Ryzen 7 9700X 8-Core CPU Benchmarks Leaked: 11% Faster Than 7900X and 10% Faster Than 7700X in Cinebench

New benchmarks of AMD’s 12-core Ryzen 9 9900X and 8-core Ryzen 7 9700X “Zen 5” desktop processors have leaked in Cinebench.

12-Core AMD Ryzen 9 9900X Is Up to 11% Faster Than 7900X and 8-Core Ryzen 7 9700X Is Up to 10% Faster Than 7700X in New Cinebench “Zen 5” Benchmark Leak

In the latest round of benchmark leaks, HXL (@9550pro) has shared the Cinebench R23 performance of the AMD Ryzen 9 9900X and Ryzen 7 9700X “Zen 5” desktop processors. The performance measured here may have been done in default configurations, but the single-core score could hint at PBO, as we’ve also seen similar single-core scores with the PBO implementation on previously leaked AMD Ryzen 9 9950X benchmarks. Let’s start with the specs of both chips.

The AMD Ryzen 9 9900X “100-000000662” processor is a 12-core, 24-thread variant. This chip has a base clock of 4.4 GHz and a boost clock of up to 5.6 GHz with a 76 MB cache. What’s interesting about this chip is that it has a TDP of 120 W which is much lower than the 170 W of the Ryzen 9 7900X chips.

The AMD Ryzen 7 9700X “100-000001404” is designed for the mainstream and features an 8-core processor with 16 threads, a base clock of 3.8 GHz, a boost clock of up to 5.5 GHz, 40 MB of cache (1 CCD with 32 MB L3 + 8 MB L2) and a low TDP of 65 W which is also much lower than the 105 W TDP featured on its predecessor, the Ryzen 7 7700X.

The Ryzen 7 7700X has a 105W part while the AMD Ryzen 7 9700X has a 65W part which is almost half of its TDP and this means that the clocks take a slight hit, with the base clock being -700 MHz lower, but the boost clock is rated at +100 MHz. For the 65W SKUs, AMD recommends using a high-end air cooler for optimal performance, but even with such a low TDP, AMD makes sure that enthusiasts don’t miss out on overclocking and tuning features, as the Ryzen 7 and Ryzen 5 chips come with all the benefits of the high-end Ryzen 9 SKUs based on the Zen 5 core architecture.

In terms of single-core performance, the AMD Ryzen 9 9900X “Zen 5” processor scores 2,232 points while the Ryzen 7 9700X scores 2,280 points. In terms of multi-core performance, the Ryzen 9 9900X scores 32,216 points while the Ryzen 7 9700X scores 21,533 points. Here’s how the performance compares to other current-gen offerings:

In multi-core, the AMD Ryzen 9 9900X is 11% ahead of the Ryzen 9 7900X while the Ryzen 7 9700X is 10% ahead of the Ryzen 7 7700X. The Ryzen 9 9900X is 9% slower than the Intel Core i7-14700K while the Ryzen 7 9700X is -13% slower than the Intel Core i5-14600K. It seems that the single-core performance of the new Zen 5 architecture is solid, with the 9900X being 11% faster than its predecessor and the Ryzen 7 9700X being 14% faster than its predecessor. Both of these processors also offer faster single-core performance than Intel’s offerings.

If these results were achieved at default TDPs, we can expect up to 16% faster performance on the AMD Ryzen 9 9900X and up to 11% faster performance on the AMD Ryzen 7 9700X with PBO enabled. By default, these chips should also consume less power and run much cooler than last-gen Zen 4 offerings, which is a plus if you don’t find the PBO option very useful to you. AMD’s Ryzen 9000 “Zen 5” desktop processors will launch in two waves, the first on August 8 (Ryzen 5 9600X / Ryzen 7 9700X) and the second on August 15 (Ryzen 9 9900X / Ryzen 9 9950X).
