We have AMD’s 4700S desktop kit, which is almost certainly equipped with a defective version of the chip commonly found in Sony’s PlayStation 5 for testing. This kit is definitely not a typical AMD product: the eight-core 16-thread Zen 2’AMD 4700S’ chip has a 3.6 GHz base and a 4.0 GHz boost, but it is directly installed on the mini-ITX motherboard and 8 or 16GB graphics memory (non-standard DRAM) And a heat sink, while the chip’s custom integrated GPU and 36 RDNA2-based computing units (CU) are disabled.This means that the chip has the ability to interact with The best gaming CPUAnd how it stands for us CPU benchmark The hierarchy depends on its ability to push discrete GPUs to high-performance levels. Today, we will test the chip in a series of tests including games and applications.
How did such a weird product come on the market? According to the latest statistics, Sony has sold more than 10 million PS5 game consoles, each with its own special customization”Oberon‘A chip designed by AMD. These custom chips are equipped with 8 Zen 2 cores and a powerful custom RDNA graphics engine, but countless chips have defects in the manufacturing process, which means that they will not function properly (if any), and usually lead to failure to garbage bucket. Sometimes the chip simply cannot meet certain clock speed standards. Regardless of the problems with these chips, they cannot be used in consoles, but AMD seems to have found a way to sell defective chips by creating a system board that contains most of the key components needed to make a small system.

AMD is certainly not known for selling almost complete systems, but it is necessary for the 4700S desktop kit, because AMD integrates a custom 75W AMD 4700S chip and eight GDDR6 memory packages onto a motherboard with BGA installation.
GDDR6 seems to be a strange addition-we usually see this type of memory for GPUs-but the 4700S uses GDDR6 as the main memory instead of the standard DRAM we are used to. This type of memory provides higher bandwidth than standard DRAM, but at the cost of higher latency. Although GPUs desire this higher bandwidth and are less sensitive to latency, GDDR6 does have a performance impact on latency-sensitive workloads (such as games) running on the CPU. In addition, the chip only exposes a PCIe 2.0 x4 interface for users to connect to PCIe devices, which ultimately limits GPU performance. It also has extremely limited I/O connectivity, with only two SATA ports for storage devices.
Almost all the details about the AMD 4700S desktop kit come from Product list and leaks Before AMD even listed the chip on its website, the company launched the AMD 4700S without any normal communication with the media through briefings or press releases. AMD also did not release chip specifications, such as clock speed, cache, and TDP, until we asked for it a few months after the system started shipping.
AMD declined to comment on whether the AMD 4700S chip contains a defective PS5 chip, but the same chip package and completely unique system requirements (such as GDDR6) indicate this. AMD also obviously avoids using the Ryzen brand.
AMD has not yet worked with independent software vendors (ISV) to provide the usual level of support for the chip, so most common monitoring utilities cannot provide accurate monitoring information, including some basic parameters such as clock speed. AMD’s own Ryzen Master does not support this chip either. All these combined make this system a black box in many ways.

what Do we know? We know that AMD has positioned the Ryzen 4700S Desktop Suite as a “high-performance productivity” solution for mainstream, home office, small business and enterprise use. This means it is suitable for tasks such as productivity, multitasking, and light 3D workloads. AMD sells the kit to a system integrator (SI), and they use the unit to create a complete system (more than 80 designs are coming soon), or as a boxed item. The system based on this kit was first listed in China, but the system and the standalone kit have now been filtered to Europe. However, AMD has not yet indicated whether the system will be available in the United States.
You will notice AMD special No Positioning the 4700S desktop kit for the gaming system. You will soon understand why.
Overall benchmark TLDR:
In the next few pages, we will dive into the various benchmarks behind these cumulative results, but these slides provide a quick summary of our test results. The first two slides show the game performance, while the last two slides show the performance of single-threaded and multi-threaded applications.
Please be sure to click on the following page to conduct targeted tests. These tests help explain why we see such low performance in games and single-threaded tasks. We also delved deeper into the benchmark results and test methods, as well as the last part of our overall analysis.
First, let’s browse the following pages through the system we purchased from a Chinese retail store, and then run the benchmark.
