Ryzen 9 7900 and Ryzen 5 7600 review: Zen 4 without the X factor

Ryzen 9 7900 and Ryzen 5 7600 review: Zen 4 without the X factor

On January 10, the Ryzen 7000 family will welcome new members, the non-X TDP 65W Ryzen 7000s. We look at the performance of two representatives, Ryzen 9 and Ryzen 5, in games and applications. As convincing as the X versions despite the more restricted TDP?

The non-X Ryzen 7000s that were made official at CES 2023 will ship tomorrow: the Ryzen 9 7900, Ryzen 7 7700, and Ryzen 5 7600. Like the Ryzen 7000X released last year, these new chips benefit from 5nm etching of TSMC and Zen 4. CPU architecture However, its TDP is reduced to 65 W, compared to 105 / 120 W for the Ryzen 7000X. With what performance impact? Answer in this test, which refers to Ryzen 9 7900 and Ryzen 5 7600, and was carried out in collaboration with Igor Wallossek.

Ryzen 9 7950X and Ryzen 7 7700X review: Zen 4 calmly starts the AM5 era

test platforms

Regarding the test conditions, the AM5 platform for Ryzen 9 7950X, Ryzen 9 7900X, Ryzen 7 7700X and Ryzen 5 7800X consists of an MSI MEG X670E ACE motherboard with 32 GB (2 x 16 GB) of Corsair Dominator RGB memory DDR5-6000. The AM4 chips (Ryzen 9 5950X, Ryzen 9 5900X, Ryzen 7 5800X and Ryzen 7 5800X3D) take place on an MSI MEG X570 Godlike motherboard with 32 GB of Corsair Dominator RAM, but DDR4-3200 type. Finally, the Intel LGA1700 platform for Intel Cores (Core i9-13900K, i9-12900K, Core i7-12700K, Core i5-13600K) mobilizes an MSI MEG Z690 Ace motherboard and 32GB of Corsair Dominator RGB DDR5-6000 memory.

The power supply common to all these setups is the Be Quiet! Dark Power Pro 12 1500 Watts. The graphics card, the MSI Radeon RX 6950XT Gaming X Trio OC. As for the cooler, this is a custom Alphacool Core water cooling system with Alphacool Apex thermal paste. The operating system is the latest version of Windows 11 Pro 2H22.

gaming performance

Let’s start with the main course for many customers, gaming performance. We did comparisons in HD (1280 x 720 pixels), Full HD (1920 x 1080 pixels) and WQHD (2560 x 1440 pixels). Here is our exhaustive list of games panel: Anno 1800, Far Cry 6, Shadow of The Tomb Raider, Total War Troy, Watch Dogs Legion, Wolfenstein Young Blood and Wolrd War Z.

At 720p, the Ryzen 9 7900 slots in behind the Ryzen 5 7600X; the Ryzen 5 7600 slides between the Core i5-13600K and the Core i7-12700K. The differences are still quite small, around 7 frames per second between the two extremes. On the other hand, even the Ryzen 5 7600 is significantly ahead of the previous generation Ryzen 5000X, with an advantage of almost 29 fps over the Ryzen 9 5950X. However, the Ryzen 7 7800X3D, once the king of 1440p gaming, remains out of reach for non-X Zen 4 chips by this definition.

At Full HD, the Ryzen 9 7900’s higher number of CPU cores works in its favor: the Ryzen still trails the Core i5-13600K, averaging 245.4 frames per second, but widens a good gap on the Ryzen 5 7600 and his average of 231.6 IPS. The latter remains ahead of the Ryzen 5000X, with an advantage of just under 15 IPS over the Ryzen 9 5950X.

Let’s not end with the QHD, definition in which Intel’s Raptor Lake shines. Unsurprisingly, with an average of 185.9 IPS, the Ryzen 5 7600 has the worst performance of the next-generation processors. As for the Ryzen 9 7900, left behind by the Core i5-13600K, it offers a frames per second average almost equivalent to that of the Ryzen 9 7900X.

Performance benchmarks and professional applications

Now we come to synthetic benchmarks and professional applications. Below you will find the performance of the processors in Cinebench R23, Blender, AutoDesk CAD or Inventor 2021 Pro. We will not comment on each performance, all of these results being quite specific. In general, the Ryzen 9 7950X and Core i9-13900K stand out, with different hierarchies depending on the scenario. The Ryzen 9 7900 does not disappoint given its TDP, while the Ryzen 5 7600 logically struggles more in multi-threaded tasks.

Consumption and energy efficiency

As you can see, in terms of pure performance, the generational gains are there. But what about the consumption and energy efficiency of these Ryzen?

In gaming, the Ryzen 9s rarely offer the best watts to frames per second ratio. The Ryzen 9 7900 is no exception to this rule. It does better than the Ryzen 9 7900X in this area and is among the good students, without leading the class. And for good reason: this title now goes to the Ryzen 5 7600, the new champion of gaming power efficiency, across all three definitions (720p, 1080p, and 1440p). It outperforms the Ryzen 5 7600X and Ryzen 7 5800X3D, often by very little.

In professional applications, the Ryzen 5 7600 and especially the Ryzen 7 7900 show excellent performances, especially in view of their performance for the latter.

Conclution

There’s not much to complain about with these non-X Ryzen 7000s. Overall, performance is in line with what we’d expect from Zen 4 chips scaled down to 65 W TDP. For most users, in view of the higher energy efficiency, the loss in performance compared to the Ryzen 7000X is quite acceptable.

Naturally, these 65W TDP processors are more attractive than their 105/120W TDP counterparts, with official prices a few tens of dollars lower than the Ryzen 7000X. On the eve of this launch, AMD has not yet communicated prices in euros. However, a reality to remember: since Black Friday, the prices of the Ryzen 7000X are much lower than those recommended at launch; so much so that in dollars they are close to those recommended for the Ryzen 7000 (see table at the beginning of the article).

So, we’re curious what quantities the non-X Ryzen 7000s will trade at. Cooler economics aside (the ones supplied, including the Wraith Prism, should satisfy most uses), the difference in price between the two ranges could be small.

Finally, we are also waiting to see what the competition, Intel, will offer with its Raptor Lake no K at 65 W of PBP. Several of these chips will be able to claim a higher number of CPU cores compared to the Ryzen of the same series, a feature that could make them more attractive and tempting to buyers. Also, the Raptor Lake platform is cheaper overall thanks to 600-series motherboards and DDR4 memory support, compared to DDR5 for Ryzen 7000s alone.
