Wang Sicong's one million computer? I haven't heard of a lot of equipment, so why is it so expensive?

He also said that his computer is expensive, and the key point is "expensive", and the principle is "expensive". So for Wang Sicong, it is no surprise that the price of this computer is hundreds of thousands of millions. Now, he can afford the money. The main accessories are: CPU: EPYC 7763 Two server motherboards + chassis: Dell R7525 Memory: Hynix DDR4 3200 RECC 64GB (32 pieces) Graphics card: Gigabyte RTX3090 (three pieces) Hard disk: PM1643 30TB (16)+PM1733 15TB (4)+P5800X 1.6TB (4) Others such as radiator and power supply are not important anymore. Take a look at CPUEPYC 7763, which is a server product of ZEN3 architecture released by AMD a while ago. The code name is Milan, with 64C128T specifications, and then the single-core maximum turbo frequency is 3.5GHz, and the L3 cache has 256MB. The CPU of the server platform is generally more expensive than the high-performance desktop level. The platform can support RECC memory, and the supported memory capacity and channels will also be larger than those of mainstream platforms. Then, with the increase in the number of cores, the price increase does not increase in a straight line. For example, go to Taobao to buy a 3960X box for only 10,000. In the beginning, this is 24C48T. But if I buy a 3970X with the same architecture, I only need to spend about 1.3W and have a 32C64T. However, the 64C128T U of the 3990X is generally sold for about 3W, so this top-scale processor is usually significantly more expensive than the one-level and two-level processors. In addition, according to the statement in the video, this U was obtained by a lot of talents, but I searched on Taobao and found a dealer who sold 7763. Of course, I don't know if the dealer who sells U really has one. This thing, or just hang up a link to buy it and book it. The price is less than 60,000. In short, this CPU is very advanced, and then it is a server-level CPU, and the throughput is also very terrifying. Traditional multitasking processors The ability is also in the top echelon, and Wang Sicong also bought two. The so-called special channel has been taken, so the price of these two CPUs adds up to 13W. The motherboard and the chassis are not important. Compared with our traditional chassis and motherboard: the motherboard and the chassis of the server pay more attention to the specific functionality, and are not as fancy as the traditional host and chassis. This kind of system will basically be equipped with a large number of hard disk interfaces, because Some uses are that you need to connect so many hard disks. This kind of hard disk is usually sold in a package, and it will be very expensive. It costs tens of thousands of sets of memory. With this memory capacity, I want to know how long it will take for the host to POST, such a large set of memory. Capacity, it will take ten minutes or more to complete all self-tests, unless you manually go to the BIOS to set skip memory self-tests, such a large-capacity single memory, 64GB single, this should be RECC memory, ordinary ECC memory is still I can't do such a large capacity, such a large memory capacity, with two 7763s, the throughput of the whole system is huge, the server is just like this, I can only say that it is good to have money, a single ddr4 3200 RECC memory I go to Taobao to search, it is cheap At this price, Wang Sicong's 32 memory will cost more than 60,000, and then the hard disk. The hard disk has spent a lot of budget here. Let's not say whether SSD or HDD is better on this server. This answer does not want to discuss this issue. The hard disk is really burning money for the sake of burning money, because if you really want to save money, if you replace a large number of HDDs, you can save hundreds of thousands, but the word saving does not seem to exist. In Wang Sicong's dictionary, Samsung PM1643 30.72TB is Samsung's SAS SSD. You can look at the official data: I searched on Taobao. Basically, a single disk of 30.72TB costs 50,000, and 16 such hard disks. It will cost 800,000, read as "800,000". If you buy a lot, it may be cheaper. If you buy more than 700,000, you will get the Samsung PM1733 15.36TB. This is also Samsung's enterprise-level solid state. The so-called enterprise-level solid state is relatively It is said that the lifespan and stability are far stronger than the solid state of the ordinary consumer market, and it also has power-down protection. The new server-grade solid state is something that rich people can afford, and the price is far more expensive than the ordinary solid state, because Enterprise-level solid-state has many advantages. Some retired enterprise-level solid-states are favored by enthusiasts. Because of their extremely high lifespan, even if they are brushed for two years, they may not be able to be written in half. Not much, even if it is a half-life enterprise-level SSD, as long as the price is right, there are enthusiasts who are willing to pay for this solid state. /S, random read up to 1500K IOPS. Sequential writing is 3.5GB/S, and random writing speed is up to 135K IOPS. I checked this disk on Taobao. There is only one for sale, and the price is 26,000. In terms of 4 yuan, this is in the early 100,000 yuan and then there are four more Zhang Intel's Optane P5800X 1.6TB, the Optane series SSD has always been the top solid state in the hearts of computer gamers, and the P5800X is a new generation of Optane, which is the Optane of PCIe 4.0, like the previous P4800X and 905P. PCIe3.0 Optane Optane series solid-state has two particularly obvious strengths compared to ordinary solid-state. First, the random read and write performance is completely unmatched. If you only look at this one, the mainstream solid-state drives in the world are now on sale. There are only two kinds - Optane solid state and other solid state and then the lifespan is extremely terrifying. I have briefly written the popular science of the lifespan of solid state drives before. To put it simply, there are two indicators, one directly tells you how much TBW, this is a write value, of course, this is not the life limit of this solid state, this is the warranty life, that is, if you write to this value, you will lose it directly. Warranty. Then there is DWPD. This parameter is also the corresponding warranty life. This indicator represents how many times you can write to the entire disk every day during the warranty period. For example, the P5800X can write up to 100DWPD, that is, write 100 times a day, and then continue to write to the warranty for several years. When the time is up, then the warranty is void. Generally speaking, the expiration of the warranty life of the solid state does not mean that the solid state is about to die out, it just means that the solid state has lost its warranty and can continue to be used as long as it does not fail. Of course, if you rarely write, you will lose the warranty when the official warranty period is reached, but the solid state can continue to be used. For the Optane solid state, the master controller may hang before the particles. The P5800X 1.6TB, four, is also spent for money, which adds up to nearly 100,000, three 3090, Gigabyte's turbo card, almost 5W. After doing the math, I compared the data from Taobao. It is about 120W, which is similar to the data transmitted on the Internet. For example, the hard disk will definitely not be the data that I directly multiply. The price he actually bought is likely to be higher. Generally speaking, the lower ones are for spending money, and the most expensive is mainly on the hard drive. The happiness of the rich is so unpretentious and boring. I am more interested in his 3990X computer, because this computer Computers might be a little more interesting.
