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 ESTSPEC2017 Multi-Threaded Results
Although single-threaded performance is important and Zen 4 has a clear advantage here, multi-threaded performance is also very important. Some variables to consider when evaluating multi-threaded performance is that desktop processor designs typically boost a single core higher, with the rest lagging in frequency behind to either stay under the thermal (TJMax) or power (TDP) envelopes. Some manufacturing processes are more efficient by design due to extensive R+D and product management, with Zen 4 looking to be much more in terms of perf per watt over Intel's Alder Lake architecture.
In the instance of the AMD Ryzen 9 7950X, it has a clear advantage over its predecessors in that it not only has a higher single core boost (5.7 GHz versus 4.9 GHz), but it also has a higher TDP than the Ryzen 9 5950X (170 W versus 105 W. This increase in TDP not only allows for a higher frequency, but it allows for a higher frequency spread across all of the cores when under full load.
Opening up our look at our SPECint2017 NT results, and we see a similar uplift in performance gains as we did in the single-threaded tests. In tests such as 500.perlbench_r, the Ryzen 9 7950 is 38% ahead of AMD's previous generation Ryzen 9 5950X, which is impressive. In 523_.xalanbmk_r, the Ryzen 9 7950 is 55% ahead of the Ryzen 9 5950X, and over 100% better in performance over the Zen 2-based Ryzen 9 3950X.
In our SPECfp2017 NT testing, certain workloads such as in 538.imagick_r showed massive increases in performance over previous generations, with a 30% uplift in performance over Zen 3. The difference here between Zen 3 and Zen 2 was marginal (10%), but Zen 4 is a more efficient core architectural design, with many improvements across the board playing a hand here; the switch to DDR5 versus DDR4, more cache per core, higher frequency, higher TDP, etc.
Overall AMD's Zen 4 architectural differences and improvements show that not only does AMD have the crown for single-threaded performance, but it's also ahead in multi-threaded performance too, at least from our SPEC2017 testing. As always when Intel or AMD makes a claim on IPC performance increases, AMD seems to be about right with claims of around 29% in ST performance and even more so in MT performance.

All Microsoft customers are QA testers, lol. That's always how it's been. ReplyKangal - Tuesday, September 27, 2022 - link
Isn't that what goes for Linux?The only difference is that you don't pay money, you just pay in time, effort, frustration, and your soul.

Exactly. And you compile your own kernel for 24 hours hoping it will finish successfully. Replyat_clucks - Wednesday, October 19, 2022 - link
Not if you use the latest Ryzen 9 7950X. You may still pray it's successful at the end but God will answer a lot faster :). Replyelforeign - Monday, September 26, 2022 - link
Ah yes, the capitalistic adage of less is more. I'm sorry you guys have to deal with this, as with anyone in the workforce, where the powers that be sit on their ass with their cushy millions and say workers can do less with more and pile on with disregard.On a further note, I have been coming to Anandtech since the mid 00's. While I can understand the expectation surrounding good grammar and flawless articles, some issues are bound to come up now and then. The vitriol you guys receive for some simple grammar or syntax mistake is crazy. Reply

Kind reply, thanks. Hope your week lets you catch up.No more copy editors?! I guess my blonde is all now truly grey . . . sigh Reply

I for one thoroughly enjoyed your article, and appreciate the technical content - a few editing nits don't detract from that.And hey, if I were to whine about embarrassing editing mistakes, rather than focusing on a long article written in limited time due to AMD's schedule, I'd poke fun at the 100 000 000 000 $ company's press slides touting their EXPO tech's openness in the form of public "doucments". 😀 Reply

So long as you're open to community feedback to correct hasty errors, there's no need for copy editors, and you can push your articles faster, which we'll all appreciate. Saying thanks is much more productive than making excuses. It shows that you appreciate your community. Reply
