AMD Ryzen® 7000 series Launch, with new Zen 4 Architecture
AMD finally announced the highly anticipated Ryzen® 7000 series with the new "Zen 4" architecture and on the new AM5 platform. Built on the new process node, it is the first 5nm CPU for Desktop. These CPUs will be available worldwide from September 27th 2022.
AMD announced 4 CPUs with AMD Ryzen® 9 7950X at the top of the line with a massive 16 cores, 32 threads, 80MB Cache (L2 + L3), and boost clocks of 5.7GHz. AMD claim a 13% uplift in Instructions per Clock (IPC) and a 29% total single-threaded performance gain, which is great news for both gamers and creators. According to AMD, these CPUs delivers on average 15% more performance for gaming and an average of 40% for creators as compared to the Ryzen 5000.
Here is a breakdown of the four CPUs:
| Processors | Cores and Threads | Cache(L2+L3) | Base and Boost clock speed | TDP | Price |
|---|---|---|---|---|---|
| Ryzen 9 7950X | 16 cores/32 threads | 80MB | 4.5GHz Base, 5.7GHz Boost | 170W | $699 |
| Ryzen 9 7900X | 12 cores/24 threads | 76MB | 4.7GHz Base, 5.6GHz Boost | 170W | $549 |
| Ryzen 7 7700X | 8 cores/16 threads | 40MB | 4.5GHz Base, 5.4GHz Boost | 105W | $399 |
| Ryzen 5 7600X | 6 cores/12 threads | 38MB | 4.7GHz Base, 5.3GHz Boost | 105W | $299 |
Benchmarks
AMD showed benchmarks against Team Blue's giant Intel Core® i9-12900K.
In V-RAY rendering benchmark it score over 30,000. It manages to deliver 62% more performance yet still at 47% better performance per watt.
In Geek Bench it delivers faster single-threaded performance as shown in the graph below.
F1 2022, It consistently delivers higher frames per second and on average 11% faster than 12900k
On average, it offers 5% faster gaming performance
Zen 4 core Architecture
The new chips use the new Zen 4 architecture which AMD claims that it delivers high performance right on schedule. The new architecture offers
- ~13% core IPC(Instructions per Clock) uplift.
- new Front end design to better feed the execution pipes
- Support for AVX-512 for machine learning and high computation
- use of 5nm cutting edge process node.
The uplift in IPC is due to L2 Cache Doubling, new Front End for feeding instructions faster to the machine, Execution engine, branch predictions and load/store.
Using AVX-512, AMD claim a 1.3X improvement of FP32 inference operations. There is also added extensions for CNN (Convolutional Neural Networks) with VNNI (Vector Neural Networks Instructions).
Zen 4 provide a 62% lower power while providing 49% more performance than Zen 3.
AM5 Platform
AM5 platform has a new 1718 LGA(Land Grid Array) socket. The new platform has an expanded socket power delivery to 230W to give headroom to unlock maximum all core performance.
AM5 also provide support for DDR5 and PCIe® 5.0 for performance growth.
Finally, AMD has maintained support for AM4 coolers to ease transitioning to AM5.
Motherboards
There will be two classes of chipsets available, X-series and the B-series. The X-series(X670, X670 Extreme) will be available in September at launch while the B-series will be available from October.
The X-series provide the highest power delivery, overclocking headroom across CPU and memory and most I/O.
AMD X670 offers PCIe® 5.0 storage support and optional graphics for enthusiast overclocking while X670 Extreme offers storage and Graphics PCIe® 5.0 support for extreme overclocking capabilities and connectivity.
B-series boards (B650, B650 Extreme), B650 is designed for mainstream users with support for DDR5 and optional PCIe® 5.0 support. B650 Extreme is for performance users with PCIe® 5.0 storage support and optional graphics support.
In summary, compared to core® i9-12900K AMD Ryzen® 7000 provide 11% faster single-threaded performance, 44% higher multi-threaded performance and 47% more performance per watt.
