Hands-on test: AMD Ryzen 7 7700X and Ryzen 9 7950X

Hands-on test: AMD Ryzen 7 7700X and Ryzen 9 7950X

AMD has launched its Ryzen 7000-series desktop CPUs based on the company’s 5nm Zen 4 architecture. We were sent a Ryzen 7 7700X and a Ryzen 9 7950X for testing.

AMD also provided a Gigabyte X670E Aorus Master motherboard and 32GB of GSkill Trident Z5 RGB DDR5-6000 memory. I paired this with an AMD Radeon RX 6600 XT and a 500GB Samsung 970 Evo Plus NVMe M.2 SSD installed with Windows 11.

The new chips support PCIe 5.0 and DDR5. They also use AMD’s new AM5 socket specification. While my Corsair AM4 AIO cooler will fit in the new socket, not all coolers may.

The Ryzen 7 7700X is a desktop CPU with eight cores and 16 threads. It has a base clock speed of 4.5 GHz, which is boosted to 5.4 GHz. It’s unlocked, so it’s overclockable if you’re so inclined.

The Ryzen 9 7950X desktop CPU bumps the core count to 16 and threads to 32. This is AMD’s flagship Ryzen desktop CPU. It has a base clock speed of 4.5GHz and a maximum boost speed of 5.7GHz. This CPU is also unlocked again.

The CPUs were evaluated using a range of consumer and professional benchmarking applications. PCMark and Crossmark use open-source office and creative software for real-world results. I also used Procyon’s image and video benchmarks to test Ryzen 9’s performance for Adobe Lightroom and Premiere Pro. The 3D rendering capabilities were checked with Cinebench R32. I also ran UL’s 3DMark to test gaming prowess, although this was primarily a test of GPU capability and not CPUs.

In addition to the results for the Ryzen CPUs, I also ran similar tests on a PC with Intel’s flagship desktop CPU, the Core i9-12900K, for comparison. The Intel machine ran DDR5 memory and an Nvidia RTX 3090 graphics card.

In general, both the Ryzen 7 7700X and Ryzen 9 7950X CPUs beat the 12th place in all teststh Generation Intel CPU. However, some of the results have been closed.

For the general productivity application test, there was very little between all three CPUs. The Ryzen 7 only just beats the Core i9 in most tests. However, the Ryzen 9 outperformed the Intel Core i9 CPU across the board, except oddly in the Procyon Adobe Premiere Pro video editing benchmark.

It only became interesting in the multi-core tests. The Intel CPU performed better in most multi-core application tests compared to the Ryzen 7, but it was the Ryzen 9 CPU that came out on top.

Most Crossmark benchmarks seem to refer to single-core CPU performance. The overall scores were pretty close, reflecting the similar base clock speeds of each CPU. I wouldn’t expect office applications to test one of today’s CPUs, as the fairly similar productivity scores show. The Ryzen 7 just beat the Ryzen 9 in the Crossmark productivity score, that’s more of an anomaly and not really worth thinking about. The Crossmark creative tests upped the AMD CPUs somewhat, likely due to the use of multi-core test applications, but still with all CPUs yielding very similar results.

The PCMark scores seem to account for both single and multi-core performance. The AMD CPUs were neck and neck (but better than the Intel CPU) in all but the digital content creation test. It stands to reason that the Ryzen 9’s 16 cores give it an advantage over the Core i9’s eight performance cores and eight (less powerful) efficiency cores and the Ryzen 7’s total eight cores in multi-core imaging and video rendering operations .

For the Procyon test, which uses real Adobe applications, I placed AMD’s Ryzen 9 and Intel’s 12th Generation Core i9 head to head. As expected, the AMD CPU performed better in the photo processing result. It was curious why the video editing test won the Intel CPU by a clear margin. I ran this test twice to be on the safe side and got the same result.

The Cinebench R23 tests simulate software-based 3D rendering via the CPU. There are two tests, one with only one core to render a photorealistic 3D image and one with all CPU cores. In these benchmarks, the two Ryzen CPUs achieved similar results for the single-core test, with both slightly beating out the Intel CPU. In the multi-core test, the Ryzen 9 was a clear winner, around 25% faster than the 12th-gen flagship Intel CPU. This was followed by the Ryzen 7 with a score of around 25% less than the Intel CPU. For me, this result is the clearest indicator of the difference between the CPUs and where the strengths of the AMD CPUs lie.

For the 3DMark tests, the 3DMark total score and the GPU score can be ignored as they mainly reflect the performance of the powerful Nvidia RTX 3090 GPU compared to the powerful AMD Radeon RX 6600 XT GPU. However, in the 3DMark result, there were only very small differences between the two AMD CPUs, which indicates parity when gaming. The 3DMark CPU score was a different story as the Ryzen 9 was ahead of both the Intel Core i9 and Ryzen 7.

It’s worth noting that benchmarks are just a guide. Everyone evaluates performance differently. So I like to run a few test applications to get a better feel for the results. CPU performance also depends on many factors such as motherboard, memory, BIOS configuration and cooling efficiency. No two PC configurations deliver the same benchmark result.

By including results from the Intel CPU that I’ve been using in my main PC for a while, I’ve gained a better understanding of how Ryzen CPUs stack up in real-world situations. While the benchmarks gave me enough to form a reasonable opinion about AMD’s CPUs, real-world tests can’t be beat.

With its 16 cores, the Ryzen 9 7950X showed a clear strength in multi-core operation. While the Procyon Adobe Premiere Pro test was a bit lower than I expected, the CPU performed much better when rendering a real edited video in the Adobe video editor. A heavily edited and titled 1 minute 20 second video took just under a minute to render; a render time that I find very acceptable. The above, along with the benchmarking results, suggest that AMD’s Ryzen 9 7950X should appeal more to users engaged in creative work such as image and video editing and 3D rendering.

The Ryzen 7 7700X performed well and at a level comparable to the 12th-Gen Intel Core i9 on all but the most intensive multi-core applications. Despite the Radeon RX 6600 XT being a 1080p GPU, the Ryzen 7 7700X had no issues running it Marvel’s Spider-Man at 4K. For pure gaming, the AMD Ryzen 7 7700X would be my choice as AMD CPU.

With the Ryzen 7 7700X at AU$700/NZ$800 and the Ryzen 9 7950X at AU$1200/NZ$1400, they don’t come cheap. The Intel Core i9-12900K currently costs around AU$900/NZ$1000. The new 13th Generation i9-13900K, which also supports PCIe 5.0, costs around AU$1100/NZ$1200.

Both the AMD Ryzen 7 7700X and the Ryzen 9 7950X are very powerful CPUs. Which one is right for you depends heavily on your budget. Both are good for the full range of desktop activities, from Office apps and content creation to enthusiast-level PC gaming.

From my testing, with the added expense of the Ryzen 9 7950X, AMD is aligning the CPU more towards users who want to make the most of the extra cores for creative endeavors. Gaming with the extra cores has some advantages, but your best bet would be to spend your money on a more powerful graphics card.

While cheaper, the Ryzen 7 7700X isn’t a problem, beating Intel’s flagship 12th Next generation desktop CPU in all but the most demanding applications. Perfect for general office tasks, content creation, and definitely high-end gaming, the Ryzen 7 7700X offers the best value for money of the two AMD CPUs.
