Last week’s data results show that the AMD Ryzen 9 7950X in its “out of the box” state does nothing with Linux, faster than enabling the previous security mitigations.

AMD Ryzen 5 7600X CPUs can show positive results with security mitigations turned off in a small subset of tests, mostly in the numerous synthetic kernel benchmarks tested, but also in the just-released Linux 6.0 operating system.

However, OpenJDK Java, database workloads, some other workloads, and web browser tests negatively impacted Ryzen 5 7600X-based test systems when security mitigations were disabled.

In Spectre V1, from a Linux 6.0 perspective, Spectre V1 mitigates the _user pointer sanitization and usercopy/SWAPGS barriers, while disabling the speculative store bypass for SSBD/Spectre V4 security mitigations via prctl. Spectre V2 affects the system differently because of the inclusion of Retpolines, IBRS firmware, normal single-threaded indirect branch predictor, conditional indirect branch predictor barriers, and return stack buffer fill.

The latest AMD Zen 4 architecture is not affected by any known CPU security flaws.

Larabel also found that on his AMD Ryzen 5 7600X CPU test system, disabling the Spectre V2 mitigation had a huge negative impact on the performance of the Zen 4 architecture. However, when the Spectre V1 security mitigations are disabled, the performance impact is negligible.

Compared to Intel’s offerings and previous Zen cores, the AMD Zen 4 architecture is more optimized and responds better to Spectre V2 mitigations. Instead of disabling security measures for optimal performance, he advises users to keep the settings at their defaults.

The sharp dragon 5 7600X is the sharp dragon 7000 first model in the lowest specifications, frequency 4.7-5.3GHz, a three-level cache of 38MB, and thermal design power consumption of 105W.

And the sharp dragon 7 7700X is based on the new TSMC 5nm process, using a new generation of AM5 slot (changed to LGA installation method), the base frequency of 4.5GHz, accelerated frequency of 5.4GHz, with 8 cores and 16 threads, L2 cache 8MB, L3 cache 32MB, TDP set to 105W.

Compared with its predecessor, the Dragon 7 5700X, the Dragon 7 7700X not only ushered in a process upgrade, the frequency has also increased significantly, and the L2 cache has also been doubled.

AMD did show official performance numbers for the Ryzen 7000 desktop CPU in Geekbench 5, but those numbers were based on single-threaded tests only. Now we can see the single-core and multi-core performance data.

The two CPUs were tested on the ASUS ROG Crosshair X670E Extreme (Ryzen 9 7950X) and MSI X670E ACE (Ryzen 5 7600X) motherboards, but both with 32 GB of DDR5 memory. These are official retail samples, as evidenced by the clock speeds. The 16-core chip runs at slightly more than 5.7 GHz, while the 6-core chip runs closer to 5.4 GHz.

The AMD Ryzen 9 7950X retains the 16 cores and 32 thread count of the previous two generations. The CPU will have an impressive 4.5 GHz base frequency and a boost clock of up to 5.7 GHz (5.85 GHz F-Max), which will make it 200 MHz faster than Intel’s Alder Lake Core i9-12900KS, which has a boost frequency of 5.5 GHz on a single core.

The Ryzen 5 7600X is 6-core and 12-threaded, with a high base clock of 4.7 GHz and a single-core acceleration frequency of 5.3 GHz. The CPU will also run at 105W TDP (142W PPT), well above its predecessor’s 65W, although again this is the sacrifice you have to make to get faster clock speeds. The CPU will carry 38 MB of cache from the 32 MB L3 and 6 MB L2 on the chip, which will cost $299 and deliver a 5% increase in performance in games over the Core i9-12900K.

The AMD Ryzen 9 7950X scored 2217 single-core and 24396 multi-core points, while the Ryzen 5 7600X scored 2165 single-core and 11432 multi-core points. In terms of single cores, the AMD Ryzen 9 7950X CPU is 31% better than the Ryzen 9 5950X and definitely beats its predecessor with a 14% performance increase compared to the Core i9-12900K. The CPU is indeed 4% lower than the Core i9-13900K, but the Intel chip also runs at a much higher power of up to 350 watts. The Ryzen 5 7600X performs over 30% better than the Ryzen 5 5600X and even outperforms the Core i9-12900K.

Both chips are more than 40% ahead of their predecessors in multi-threaded tests. The Ryzen 9 7950X is also 41% faster than the Intel Core i9-12900K, and the Ryzen 5 7600X is comparable to the Intel Core i5-12600K, which has more cores and threads. These are very strong numbers, and we can’t wait to see these chips hit the market on September 27 so users can enjoy a huge performance boost.
