AMD Zen 4 Ryzen 9 7950X and Ryzen 5 7600X Review: Retaking The High-End
by Ryan Smith & Gavin Bonshor on September 26, 2022 9:00 AM ESTTest Bed and Setup
As per our processor testing policy, we take a premium category motherboard suitable for the socket, and equip the system with a suitable amount of memory running at the manufacturer's maximum supported frequency. This is also typically run at JEDEC subtimings where possible. It is noted that some users are not keen on this policy, stating that sometimes the maximum supported frequency is quite low, or faster memory is available at a similar price, or that the JEDEC speeds can be prohibitive for performance.
While these comments make sense, ultimately very few users apply memory profiles (either XMP or other) as they require interaction with the BIOS, and most users will fall back on JEDEC-supported speeds - this includes home users as well as industry who might want to shave off a cent or two from the cost or stay within the margins set by the manufacturer. Where possible, we will extend out testing to include faster memory modules either at the same time as the review or a later date.
The Current CPU Test Suite
For our AMD Ryzen 9 7950X and Ryzen 5 7600X testing, we are using the following test system:
| AMD Ryzen 7000 Series System (DDR5) | |
| CPU | Ryzen 9 7950X ($699) 16 Cores, 32 Threads 170 W TDP Ryzen 5 7600X ($299) 6 Cores, 12 Threads 105 W TDP |
| Motherboard | GIGABYTE X670E Aorus Master (BIOS 813b) |
| Memory | G.Skill Trident Z5 Neo 2x16 GB DDR5-5200 CL44 |
| Cooling | EK-AIO Elite 360 D-RGB 360 mm AIO |
| Storage | Crucial MX300 1TB |
| Power Supply | Corsair HX850 |
| GPUs | NVIDIA GeForce RTX 2080 Ti, Driver 496.49 |
| Operating Systems | Windows 11 21H1 |
As we are in a transitional period between our current CPU 2021 suite and data, and optimizing our CPU 2023 suite with different data comparisons required, we have included a varied selection of benchmarks for this review. This ranges from our traditional un-updatable Google Octane 2.0 web test, through a variety of rendering benchmarks such as CineBench R23 and Blender, to encoding, and all the way to our more scientific-related tests.
With our processor reviews, especially on a new generational product such as AMD's Ryzen 9 7950X, we also include SPEC2017 data to account for any increases (or decreases) to generational single-threaded and multi-threaded performance. It should be noted that due to the terms of the SPEC license because our benchmark results are not vetted directly by the SPEC consortium, we have to label them as ‘estimated’. The benchmark is still run and we get results out, but those results have to have the ‘estimated’ label.
Moving Foward to Our CPU 2023 Suite: What to Expect
Looking ahead to our updated CPU 2023 suite, we've updated some of our existing benchmarks to the latest and current versions (as of Sept 22) such as Blender 3.3. In terms of benchmarks from our CPU 2021 suite, we've included benchmarks such as Dwarf Fortress, Factorio, and Dr. Ian Cutress's 3DPMv2 and Crysis CPU benchmarks.
We've also added some completely new benchmarks and workloads to our suite, including an update to Blender (v3.3), C-Ray 1.1 rendering, as well as more scientific-based workloads such as SciMark 2.0 and Primesieve 1.9.0. We have also decided to add UL's latest Procyon suite which measures overall system performance when doing tasks such as office-based tasks, as well as video, and photo editing.
As it stands, we have also updated our pool of games going forward into 2023 and beyond, including the latest F1 2022 racing game, the CPU-intensive Total War Warhammer 3 real-time strategy, and the popular Hitman 3 assassin-based title.
Our aim is to provide varying levels of data points across a variety of different workloads, instruction sets, and tasks. Going forward, we will keep our CPU 2023 suite updated as frequently as possible, and when we have a consistent and suitable number of data points, it will feature on our Bench database as we continue testing new and older CPUs for varying data points.
Some of these new benchmarks will make an appearance in this review, while others won't. Our aim is to assess and subjugate our way through whatever CPUs we have on hand to add vital data points. However, some parts of our CPU 2023 suite are still under testing and it should make a full debut in our next CPU review.

Meh, time will out the ultimate price-points and all that, but as it emerges I really wonder what kind of users are looking to drop this kind of dollarses on high-end AMD builds. My gut is that they've priced themselves out of their primary demographic, and max TDP is right up there too, same as with their GPUs. When it comes down to a difference of a couple hundred bucks per build (assuming people build these with the pricey DDR5-6000 there's scant mobo support for through whatever AMD's integrated mem-OC profile scheme is) are there going to be enough users who just root hard enough for the underdog to build on these platforms, contra even high-end Alder Lake or (however much extra, reamins at time of writing to be seen) Raptor Lake builds? Before the announcements I was expecting AMD to get in cheap again, promise at least like performance for a bit of a discount, but it seems even those days are over and they want to play head-to-head. I wish them the best but I don't see them scoring well in that fight. Replytvdang7 - Thursday, October 6, 2022 - link
" I have a 1440p 144Hz monitor and I play at 1080p just because that's what I'm used to."Is this some kind of joke. We are supposed to listen to reviewers that are stuck in 2010 Reply

I’m curious as to whether there’s any appreciable difference to a consumer as to whether a particular PCIe lane or USB port is provisioned by the CPU or the Chipset…. Like, is there a reliability, performance, or some other metric difference?I’m just curious why it’s a design consideration to even include them in the CPU design to begin with, unless it has to do with how the CPU lanes are multiplexed in/out of the CPU and somehow some of the lanes can talk inter-device via the chipset without involving the cpu… Reply

Where is octa channel memory? dual channel memory is a $300 CPU.Where is native Thunderbolt 4 support?
(mac minis have had thunderbolt 3 for over 5 years).
Cant even find one X670 Motherboard with 4x Thunderbolt 4 ports. And you want $300? Thunderbolt 4 should be standard on the cheapest boards. Its a $20 chip. Reply

The mission of corporations is to extract profit for shareholders and protect the lavish lifestyles of the rich. It is not to provide value to the plebs. Do the absolute minimum is the mantra. ReplyRedGreenBlue - Tuesday, October 11, 2022 - link
That must be why Intel made Thunderbolt royalty-free and it’s now built into USB 4. ReplyOxford Guy - Wednesday, October 12, 2022 - link
It probably can afford to since states like Ohio are willing to bankroll half of the cost of its fabs. ReplyRedGreenBlue - Tuesday, October 11, 2022 - link
It’s built into USB 4 now. Just make sure it’s functional already because it might need a driver, AMD did that on the 600 series. Aside from that important fact, I don’t care if there aren't many boards with it. The thunderbolt ecosystem has been crap since the beginning. Peripheral makers didn’t take advantage of it because USB was a more common approach and intel didn’t make thunderbolt cheap to implement. The Mac Minis have it because Apple made a big bet on it when it came out. These days it’s nice to have but it’s a throw-away feature unless you have a niche product that needs it. It’s for niche purposes and that would have been a waste of pci lanes. I would’ve liked it for external GPU’s but intel effectively shut that down and I don’t know if they’ve opened the door to it again. USB is way more convenient.

And 8 channel memory, like, this sounds like a joke. That’s for server or workstation cpus because of how many layers it takes for the wiring on the board and the pins on the socket. That’s part of why server and workstation boards are so expensive. If you need that much bandwidth you’re in the wrong market segment. Look at Threadripper chips.

It would be appreciated if architecture reviews had the pipeline differences in a chart to compare across generations. Anandtech used to have that included and it gave a good comparison of different generations and competitor architectures. I can understand not including it in the product review but I don’t remember a chart being in the previous Zen 4 overview article. Reply
