Video data communication & processing machine | Information dissemination media for research and development TEGAKARI

A customer who was considering building an industrial system consulted us about a machine that controls equipment related to video and performs communication and data processing.The conditions under consideration are as follows.

・CPU: Core i9-12900T equivalent, focus on L2 and L3 cache size rather than clock
・Memory: About 16GB ECC is not essential
・Storage: SSD of about 128GB for OS, SSD of 128GB or more for primary data Since high-speed reading and writing is important, low-speed HDD should be avoided
・GPU: None is OK
・Network: 2.5 Gbps or higher port x 1, 1.0 Gbps or higher port x 3
・External I/F: USB type A x4 port
・Screen output: Either HDMI or DisplayPort is fine
・Power supply: Something that can withstand 1 to 8 hours of operation per day
・OS: Windows 10 IoT Enterprise LTSC 2021

Based on the above conditions, we proposed the following configuration.

CPU	Core i9-13900 (2.00GHz 8-core + 1.50GHz 16-core)
memory	16GB
Storage 1	240GB SSD S-ATA high durability model
Storage 2	480GB SSD S-ATA high durability model
Video	on board (DisplayPort x1 HDMI x1 DVI-D x1 VGA x1)
network	on board (2.5GBase-T x2)
Housing + power supply	4U rackmount chassis + 550W
OS	Microsoft Windows 10 IoT Enterprise 2021 LTSC 64bit Highend
Other	server adapter Rack mount rail kit

This is a configuration example assuming data communication and processing.
You requested a CPU with a large cache, but the structure of the cache capacity is somewhat fixed depending on the architecture (generation) of the CPU, and compared to CPUs of the same generation, CPUs with a large number of cores have more cache. is common.Also, with each new generation, the capacity of the cache increases.
In this case, we have selected the 12th generation Core i9, which is the successor to the 13th generation Core i9 you contacted us about.
As mentioned above, the cache (especially the L2 cache) is tied to the placement of the CPU cores, so a simple comparison is not possible, but it has more than double the L9 cache of the Core i12900-2T.

Reference: Compare 2 Intel Products *Jumps to an external site

Both storages are high endurance SSDs. For the second storage, we intentionally use a larger capacity than the one specified, in consideration of write endurance.In general, the larger the capacity of the SSD, the better the endurance as the writes are spread out.

The configuration of this case study is based on the conditions given by the customer.
Please feel free to contact us even if you are considering different conditions from what is posted.

・What is cache?
Cache memory is memory installed between the CPU and the main memory. By temporarily storing data frequently accessed by the CPU in a high-speed storage area, it reduces the number of accesses to the main memory and improves the processing speed of the CPU.The cache has a hierarchical structure of L1, L2, and L3, and L1 is the fastest because it is closest to the CPU.Cache management is done by hardware, and the CPU can access data at high speed without being aware of the existence of the cache.Since the size of the cache is small, holding data increases the cache hit rate and reduces memory access latency.
