The Sunnyvale company has finally unveiled its AMD Ryzen 4000, a generation that, like the laptop version, was built on the Zen 2 architecture and maintained the GCN architecture on the GPU side. This means that we have the same processor and graphics core design in the same package, but the architectures of both components are at different levels.
Zen 2 is a new generation that marked a significant evolution against Zen +, and offers an IPC that is, generally speaking, on the same level as Intel’s Core processors. However, the GCN architecture is an old acquaintance that has been with us since the end of 2011. It is true that AMD has been introducing improvements that have allowed an increase in performance and greater efficiency, but it should have already made the jump to the RDNA architecture, used in the new Radeon RX 5000.
The most important improvement that these new APUs bring is, therefore, focused on performance and efficiency at the CPU level. Not only do they provide processors with higher power compared to the previous generation, but they also have much higher performance per watt consumed. The AMD Ryzen 4000 is well above the 3000 series at the processor level, but not so much at the GPU level.
In the attached image you can find all the key components of the AMD Ryzen 4000 APUs. We have a monolithic design with eight cores, which leaves us with a maximum configuration of 8 cores and 16 threads thanks to SMT technology. Each quad-core block has 4MB of L3 cache memory, for a total of 8MB.
We can also see that this chip integrates all the classic elements of the “northbridge” and the “south bridge” (SATA, PCIe root, USB connectors, etc.). In the middle section, we have the Infinity Fabric interconnection system, and just below we see a Radeon Vega GPU manufactured in the 7nm process, which has a maximum of 8 CUs (computing units), which leaves us with a total of 512 shaders.
The AMD Ryzen 4000 is manufactured at 7nm, both at the CPU and GPU.
In terms of performance, we find a clear improvement compared to the previous generation. We can also see that the integrated GPUs is above the solutions that Intel uses in its ninth-generation Core processors. They are limited to 8 PCIE Gen3 lines.
AMD Ryzen 4000 APUs Availability and Pricing
AMD has confirmed that it will start providing the market sometime in the third quarter of this year, probably between August and September.
We also have the official prices of these new APUs in dollars:
- AMD Ryzen 7 4700G: 8 cores and 16 threads at 4.4 / 3.6 GHz, Radeon Vega 8 GPU, 65 Watt TDP, and 12 MB of cache. It will cost about $ 289
