AMD dropped the ultimate shock bomb to Intel !! The 64-core, 128-thread, top-level model Ryzen Threadripper 3990X processor officially debuted. The number of CPU cores has doubled compared to the previous generation. The improved Zen 2 architecture has an average performance increase of 15% and Cache capacity has doubled. Upgrade the PCIe 4.0 transmission technology and optimize the DDR4 memory controller. The official price is about US $ 3,990. Since Intel no longer has a HEDT model processor of more than US $ 1,000, the high-end market has been completely occupied by Ryzen Threadripper.
AMD Ryzen Threadripper 3990X processor
Three months later, AMD dropped the Zen 2 shock bomb to Intel again. The code-named "Castel Peak", the ultimate type of Ryzen Threadripper 3990X processor officially debuted. It is the world's first 64-core, 128-thread x86 desktop processor. The new Zen 2 micro-architecture improves IPC performance by 15% over the previous generation, benefiting from the advanced TSMC 7nm process and better voltage/clock curve setting At the 280W level, due to Intel's temporary maximum 28-core processor, the high-end HEDT platform has been fully occupied by AMD Ryzen Threadripper.

The AMD "Ryzen Threadripper 3990X" processor uses a new Chiplet design divided into CCD and IOD chips. The 8-core CCD computing chip uses TSMC 7nm. The built-in 3.9 billion transistors have a chip size of about 74mm². The cIOD chip uses the more mature GlobalFoundries 12nm In the process, 8.34 billion transistors are built-in and the chip size is 416mm². Therefore, 8 CCDs + 1 cIOD chip is required to form a 64-core configuration. A total of 33.29 billion transistors and a total Die Size of 1,008mm² are quite exaggerated.

AMD "Ryzen Threadripper 3990X" is the world's first 64-core x86 Desktop processor, mainly for multi-tasking professional applications such as 4K / 8K image special effects production, professional 3D graphics and workstation computing, compared with Intel's top core-i9 The performance of the 10980XE 18 core processor is 3X higher, which is 2.5X higher than Intel ’s highest performance Xeon W processor, and 1.3X higher than the dual-channel Xeon Platinum 8280 processor, which costs about US $ 20,000, but 3990X The price is only US $ 3,990 US dollars, both in terms of price and performance are the competitors.

| 64 Cores, 128 Threads, Total 288MB Cache |
This time I received the AMD Ryzen Threadripper 3990X processor, B0-Stepping with 64 cores, 128 SMT threads, 4MB L1 Cache (32KB + 32KB x 64), 12MB L2 Cache (512KB x) 64) and 256MB L3 Cache (16MB x 16), a total of up to 288MB Cache is really exaggerated, the basic clock is 2.9GHz, the highest Precision Boost clock is 4.3GHz, and the highest TDP is 280W.
Although the CPU specifications are provided to 64 cores and 128 threads, to fully utilize the power of Ryzen Threadripper 3990X, the operating system and software requirements are required. AMD recommends using Windows 10 1903 18362.535 or newer kernels, and ensure that the KB4530684 update file is installed. In order to maximize efficiency.
| Model | Process | Core/ Threads | L2 | L3 | Base Clock | Boost Clock | TDP | SMT | 4CH DDR4 | PCIe Support | Price |

In addition, many applications and test software are generated based on older software compilers, so they can only use up to 64 threads, so AMD actively cooperates with software developers to allow more software to support more than 64 threads. For example, the old versions of Cinebench R20 and ROV-Ray cannot support more than 64 threads, but after updating to Cinebench R20 20.06 and ROV-Ray 3.7 Final Release versions, the true strength of Ryzen Threadripper 3990X can be fully reflected, which is why 3990X The main reason for the later release is to allow more software to catch up with the update.
New Socket sTRX4 package
AMD sTRX4 LGA-ZIF Package
The AMD Socket sTRX4 processor interface is adopted. Although the mechanical structure is exactly the same as the old generation TR4 interface, the definition of 4094 LGA pins is also modified. Therefore, the Ryzen Threadripper old and new platforms are not compatible. The new Ryzen Threadripper 3990X The processor must be equipped with the new generation TRX40 platform and cannot be used on the old X399 motherboard, and vice versa.

Compared to mainstream Ryzen processors, Ryzen Threadripper processors have more computing cores, allowing users to handle more things at the same time, and have more PCIe I / O, which can be used to connect more GPUs or FPGAs. A processor, more PCIe SSD storage devices, and at the same time can support more DRAM memory modules and higher system memory capacity, which can meet the needs of high-end PC players and professional users of workstations.
