AMD Ryzen 7000 processors are here and AMD believes that it can take the crown in the ranking of the best processors. They are powered by the new Zen 4 core architecture and combine performance and power efficiency in the world’s first 5nm desktop processor. A lot is changing this generation, so we thought it was time to compare the Ryzen 7000 with the latest generation Ryzen 5000 processors.
Ryzen 7000 processors and socket AM5 will be available on September 27, but our review is out right now.
Prices
AMD
AMD’s Ryzen 5000 processors launched on November 5, 2020, and Ryzen 7000 processors will be available on September 27, 2022. It’s hard to make any predictions about stock availability when the Ryzen 7000 launches, but it’s safe to assume that the initial wave of processors to be out of stock for at least a week or two. We’ll have to see if that continues into the final months of the year.
This time it’s actually Ryzen 7000 processors more economical of the Ryzen 5000 processor at launch. This is what the lineup looks like now:
- Ryzen 9 7950X: $700
- Ryzen 9 7900X: $550
- Ryzen 7 7700X: $400
- Ryzen 5 7600X: $300
Although Ryzen 7000 is cheaper at launch, Ryzen 5000 processors are much cheaper now. They’re seeing huge price discounts now that next-gen CPUs are coming out, which means you can save big with a next-gen CPU and motherboard if you’re willing to sacrifice a bit of performance. Here’s what the current Ryzen 5000 prices look like (along with the original retail price in parentheses):
- Ryzen 9 5950X: $550 ($800)
- Ryzen 9 5900X: $390 ($550)
- Ryzen 7 5800X: $250 ($450)
- Ryzen 5 5600X: $190 ($300)
Especially between Ryzen 9 5900X and Ryzen 7 5800X, except a lot of money compared to the Ryzen 7000. These prices could drop further as retailers start selling their inventory as well.
The value and price are different, but based on our own testing, the Ryzen 7000 seems like a huge performance upgrade that could justify the price difference.
Glasses
The Ryzen 7000 and Ryzen 5000 don’t look much different on paper, offering the same number of cores and threads, but it’s the vast difference in clock speed and cache that sets them apart.
| Ryzen 9 5950X | Ryzen 9 5900X | Ryzen 7 5800X | Ryzen 5 5600X | |
| Cores/Threads | 16/32 | 12/24 | 8/16 | 6/12 |
| increase clock speed | 4.9GHz | 4.8GHz | 4.7GHz | 4.6GHz |
| base clock speed | 3.4GHz | 3.7GHz | 3.8GHz | 3.7GHz |
| Cache (L2 + L3) | 64MB | 64MB | 32MB | 32MB |
| TDP | 105W | 105W | 105W | 65W |
The most interesting note is that Ryzen 5000 processors can’t hit 5GHz out of the box, something Intel has been able to achieve for years with CPUs like the Core i9-12900K. The Ryzen 7000 breaks that barrier in fashion, albeit at the cost of power requirements.
| Ryzen 9 7950X | Ryzen 9 7900X | Ryzen 7 7700X | Ryzen 5 7600X | |
| Cores/Threads | 16/32 | 12/24 | 8/16 | 6/12 |
| increase clock speed | 5.7GHz | 5.6GHz | 5.4GHz | 5.3GHz |
| base clock speed | 4.5GHz | 4.7GHz | 4.5GHz | 4.7GHz |

At the root of each processor are its cores. The Ryzen 5000 processors are based on the Zen 3 core design, while the Ryzen 7000 uses the newer Zen 4. Zen 3 brought big changes to AMD’s architecture, improving clock speeds and consolidating its 8-core complex and L3 cache into a single resource. therefore core-to-core and core-to-cache latency was almost non-existent.
This Zen 3 architecture is what gave AMD a huge improvement in multi-threaded performance compared to Intel processors. But the Zen 4’s design is an entirely different beast.
The new Zen 4 offers up to twice the L2 cache and load/storage bandwidth and introduces RDNA2 graphics into the core. However, the jump in clock speed is the biggest change, which is probably where the extra power requirements come from, even though the processors use the more efficient TSMC 5nm process.
Zen 3 processors maxed out at 105W, while Zen 4 processors maxed out at 170W. That’s not the highest possible power consumption, either, as flagships like the Ryzen 9 7950X can go up to 230W. when they are under stress. That’s about the same as Intel’s Core i9-12900K, which is one of the most popular processors with the highest power consumption on the market.
Clearly, the Ryzen 7000 consumes more power, but AMD still emphasizes that they are more efficient processors compared to the Ryzen 5000. It’s not about how much power it uses, though. It’s all about the performance you get with that power.
Performance
In terms of raw performance, it’s not surprising that the Ryzen 7000 improves on the previous generation, but it does so in quite a dramatic way.
In our tests, the 16-core 7950X showed a 31% real-world increase over the Ryzen 9 5950X in Cinebench R23 and a 25% increase in Geekbench 5. AMD previously claimed it offers a 29% improvement over to the older generation, so the reality is better than its promises, a rarity in this industry. Even better, it’s also ahead of the Core i9-12900K by a few percentage points.
The Ryzen 7000 is even better in the multi-threaded test, beating not only the 5950X, but also the 12900K, which bodes well for future competition with Intel’s next-gen Raptor Lake processors.
These synthetic numbers are all very well, but what about the game? That’s where AMD had a bigger mountain to climb, as it had to compete not only with the Intel 12900K, but also with its own 5800X3D, which has held the gaming crown since its release earlier this year. Fortunately, the Zen 4 offers improved performance over even that mighty unit.
CPUs don’t make a huge difference to gaming performance, but they still play a role, especially when it comes to esports games and light titles that already hit high frame rates. Here we can see that the 7950X does a great job of improving performance in a variety of games.
We don’t have raw performance data for other CPUs in the Ryzen 7000 range, but it’s clear from our 7950X sample that the Zen 4 cores offer impressive performance and need to be replicated across a range of new CPUs. We’ll update our coverage when we’ve had more time to work with the new chips to confirm our suspicions.
AMD is placing a lot of emphasis on efficiency this generation, probably due to the higher power consumption of its top-of-the-line chips. The company says the overall 35% improvement at full power actually increases to a 74% improvement when the mainstream Ryzen 9 7950X is capped at 65W. Overall, AMD claims the Ryzen 7000 consumes up to 62% less power. power with the same performance as the previous generation. In our tests, it proved to be relatively efficient, putting out just over 200W at full load. But it runs on heating, so the Zen 4 may need more powerful cooling across the board to keep it running at peak performance.
Platform Features
Performance and specifications are important, but the Ryzen 7000 is very different from the previous generation due to the characteristics of its platform. Specifically, the Ryzen 7000 supports DDR5 and PCIe 5.0, while the Ryzen 5000 is limited to DDR4 and PCIe 4.0. Newer is faster and faster is better, but the features of the Ryzen 7000 platform are more future-oriented than present.
Even the best DDR5 RAM provides only modest improvements under most workloads and virtually no difference when it comes to gaming. It can offer a big boost for some memory-sensitive workloads, but they are mostly relevant in the data center, not the home PC. Similarly, PCIe 4.0 is just beginning to mature enough that plugged hard drives are readily available, so PCIe 5.0 is still quite a ways off.
The biggest advantage that the Ryzen 7000 has over the previous generation is the AM5 socket. AMD is ditching the AM4 socket it’s been using since 2016, effectively ending your upgrade path if you’re running a Ryzen 5000 now. AMD says it will continue to support AM5 through 2025 and beyond, so building a Ryzen 7000 PC opens up your options for easier upgrades down the road.
Which one should you buy?
If you’re building a new PC, the Ryzen 7000 makes the most sense. It offers a clear upgrade path and will undoubtedly at least outperform the Ryzen 5000. We’ve yet to compare the chips ourselves, but AMD’s claims are promising.
However, the Ryzen 5000 is still competitive. If you’re just upgrading your PC, you can get a great deal on a Ryzen 5000 processor and motherboard now that the next generation is here. Sure, they don’t offer top-tier performance, but they’re still pretty close considering how much money you can save right now.
