This article is I post on chinese forum if you can see the chinese you may can know the cpu article better.

Because my English is so~~ bad.

 

About soma CPU,i know some things about it.

1. "SoMa" is made of intel

2. "SoMa"maybe is a neural computing CPU

3. "SoMa"is can be use,but we don't know what mother board can use it.Ordinary motherboard can't use it

4. "SoMa"has two version.   "SoMa" and "SoMa-B3"

5. "SoMa"maybe is a EngSample For "intel Loihi CPU" (SoMa is LGA but Loihi is BGA)

6. "SoMa"is a AI CPU

7. "SoMa"is not a ordinary CPU

( ↓  Google translation  ↓ )【I made some modifications about Google Translate】

Here to talk about Intel Loihi CPU

Loihi is a member of Intel's Neural Mimic Processor and is the fifth generation of neural mimic processors.

Intel once released a neural mimic system (neural computing cluster) codenamed Pohoki Beach. This computing cluster contains 64 Loihi neural processors with an area of only about 38.4 cm². This system has more than 8 million neural units and more than 8 billion bumps.

At the same time, a single Loihi processor uses a heterogeneous design with 128 Neuromorphic Cores and 3 low-power X86 cores, with 130,000 neural units and 130 million synapses. The Loihi neural processor can be expanded to 16384 Loihi at the same time, and there will be about 2.12992 billion neural units (the human brain has about 86 billion). If 40 groups of 16,384 Loihi interconnected systems are made, the neural computing unit will be close to the number of human brains.

I haven't found this Loihi processor on eBay / Amazon / Taobao / Xianyu, including Pohoki Beach's neural computing system. It will not be cheaper than a car anyway, after all, it is a professional field device. (Note: He is not an FPGA chip, but only contains FPGA functions.) In addition, there is a full explanation of why SoMa has no capacitors: during deep learning tests, its power consumption is more than 100 times lower than that of ordinary processors. The power consumption of bit-based IoT inference hardware is also 5 times lower. Real-time performance can still be maintained after the network scale is expanded 50 times, and the power consumption is only 30% higher than the original. Even more frightening is that under the 1% occupancy rate of this processor, the power consumption is only tens of milliwatts. Therefore, SoMa's power consumption is naturally not too high.

Neural mimicry cluster system on Pohoki Beach
A system consists of 4 daughter boards and 1 mother board. Each daughter board has 16 Loihi processors. The heat sink above is actually a capacitor. Each daughter board needs a 6pin power supply. One motherboard can connect 4 daughter boards at the same time, and the daughter boards can be stacked. The main processor is still on the mother board. Below the small blue heat sink is the main processor, which looks like a relatively large power intel Atom. The motherboard should have SFP + on it and support 10GE network.Neural mimicry cluster system on Pohoki Beach’s motherboard have a text"intel Labs".So maybe we can't get the motherboard on Bay / Amazon / Taobao / Xianyu（https://www.intel.com/content/www/us/en/research/neuromorphic-computing.html）

Well, the mystery about the SoMa processor has also been solved. The SoMa processor is actually a product of the Intel Neural Mimicry Project. But it also seems to be a test product. As for why it is 100,000, everyone should also see above. This is a cluster computing system, just like a 16-way platinum 8280 server. Most people will not use these things when they come into contact with them,also don't know how to use. SoMa translates the meaning of the brain nerve, which is in line with Intel's neural calculations, and also proves the validity of this conclusion. About SoMa-B3, B3 may refer to the revision code.

Cool a low power possibly mobile chip. A xeon maybe.

Maylay just means made in Malaysia.

 

Probably nothing special about this chip at all. First glance is looks like a socket T cpu.

Yep its nice LGA1156 mysterious intel cpu. Would be much more cooler to know if you been able to lounch lol.

[ErnestJ]

Anyone been able to boot it ?
