Another AMD Ryzen 3000 series review has leaked online and this time we are looking at the CPU performance numbers of the 12 core Ryzen 9 3900X and the 8 core Ryzen 7 3700X. The review was published by PCGamesHardware.de but was removed, however, a copy of the Ryzen performance numbers was saved by users who were able to view the review.

AMD Ryzen 9 3900X and Ryzen 7 3700X CPU Review Leaks Out – Gaming Performance Similar To 9th Gen Intel Core, Ryzen 9 3900X Consumes Less Power Than i9-9900K, Ryzen 7 3700X Consumes More Power Than Ryzen 7 2700X

The performance benchmarks were carried out on an X570 motherboard (ASUS ROG Crosshair VIII HERO) with 16 GB of DDR4 Ram (configured to max specifications/clocks suggested for each CPU) and a GeForce GTX 1080 Ti. The latest drivers and BIOS were used with Turbo and SMT enabled. We will get to the performance in a bit but let’s take a quick look at the specifications of each of the Ryzen 3000 CPU that was tested.

The AMD Ryzen 9 3950X is definitely the highlight of the Ryzen 3000 series lineup since the CPU is the flagship variant but it won’t launch until September. What would launch in a few days is the Ryzen 9 3900X which will be the first 12 core processor for mainstream platforms and that too is a beast in terms of performance and efficiency.

Ryzen 9 3900X 12 Core / 24 Thread CPU For $499 US

The AMD Ryzen 9 3900X is a 12 core and 24 thread part featuring the 7nm Zen 2 core architecture. The chip features a base clock of 3.8 GHz and a boost clock of 4.6 GHz. There’s 70 MB of L3 cache, 40 PCIe Gen 4 lanes (CPU + PCH) and a TDP of 105W (derived from the base frequency). The CPU is going to hit retail on 7th July for $499 US. In terms of pricing, the chip is positioned against the Intel Core i9-9900K and offers more cores, threads, cache, PCIe lanes and support for next-gen I/O such as PCIe Gen 4.0.

Ryzen 7 3700X 8 Core / 16 Thread CPU For $329 US

The AMD Ryzen 7 3700X is an 8 core and 16 thread part featuring the 7nm Zen 2 core architecture. The chip features a base clock of 3.6 GHz and a boost clock of 4.4 GHz. There’s 36 MB of L3 cache, 40 PCIe Gen 4 lanes (CPU + PCH) and a TDP of 65W (derived from the base frequency). The CPU is going to hit retail on 7th July for $329 US. In terms of pricing, the chip is positioned against the Intel Core i9-9700K and offers more cores, threads, cache, PCIe lanes and support for next-gen I/O such as PCIe Gen 4.0.

Ok so coming to the performance numbers, both chips were tested in different gaming titles at 720p resolution (CPU bound scenario). In Far Cry 5, both chips delivered around the same CPU performance (Minimum and Max). The max FPS was pretty close to the Core i7-7700K but the i7-7700K led in terms of Minimum FPS which equals to a more smoother gameplay experience.

In Rise of The Tomb Raider, the Ryzen 7 3700X turned out on par with the Core i7-7700K but the Ryzen 9 3900X came out a slight bit ahead of the 3 generations old Intel chip. Moving on to Wolfenstein II: The New Colossus, the chips performed pretty well with about as much performance as the Core i5-8600K (6 core / 12 thread) CPU while the Core i7-7700K was a good 10 FPS faster in Min FPS.

The only game where the Ryzen chips outperformed the entire Intel lineup was Assassins Creed Odyssey where they came out faster than the Core i9-9900K with up to 6 FPS+ on minimum. When it comes to encoding performance (Handbrake: 30-sec clip, HEVT, 10 bit, 140 Mbps), the Ryzen 9 3900X was as fast as the Ryzen Threadripper 2990WX (148 secs vs 142 secs) while the Ryzen 7 3700X was as fast as the Core i9-9900K (212.8 secs vs 211.7 secs).

In Cinebench R15, the Ryzen 7 3700X delivered better performance than the Core i9-9900K with a single-core score of 207 points and a multi-core score of 2180 points. The Ryzen 9 3900X was faster than Intel’s Core i9-7980XE with a single core score of 207 points and a multi-core score of 3218 points.

When it comes to power consumption in both gaming and applications, the Ryzen 9 3900X had a power consumption lower than the Core i9-9900K while offering more cores, threads and better I/O. The Ryzen 7 3700X was, however, a bit more power hungry than its 12nm predecessor, Ryzen 7 2700X, despite the former being a 95W chip and the 3700X, a 65W chip based on the 7nm node.

AMD’s X570 platform and Ryzen 3000 CPUs are planned for launch on 7th July while the AMD Ryzen 9 3950X will be available in September 2019.
