The country keeps making baby steps into the GPU space. As a miner I think we need more competition and choice in the market – so what do you think if this could post some decent numbers would you invest?

Why it matters: China has been quietly developing CPUs and GPUs for years, but it’s been trying to accelerate existing projects without much tangible success as of late. Still, now and then, we hear about another small breakthrough made by a Chinese company. Such is the case of Jingjia Micro, which is getting closer to releasing a graphics card that could potentially come close to the performance of a GeForce GTX 1080.

So far, we’ve seen a lot more action in the CPU space from Chinese companies like Zhaoxin, which are trying to develop x86 processors that can catch up to and eventually compete with those made by Intel and AMD. However, GPUs have not seen nearly the same attention being devoted to them.

One notable exception is Jingjia Micro (also known as Jingjiawei), which started as a military-civilian company developing and manufacturing military-grade electronics. Almost three years ago, the company said it was working on its own discrete high-performance graphics card after successfully launching China’s first domestic GPU.

According to a report from MyDrivers, Jingjia Micro is getting ready to launch not one but two graphics cards. The first is an entry-level model called JM9231 that will offer performance around the level of a GeForce GTX 1050 or Radeon RX 560. The second, more ambitious one, is the JM9271, which is supposedly able to keep up with a GeForce GTX 1080 or AMD’s RX Vega 64.

Digging deeper, the JM9231 will integrate 8 GB of GDDR5 memory and offer two teraflops of FP32 performance with a TDP of 150 watts, which would be an impressive feat for the Chinese company. As for the JM9271, it will come with 16 gigabytes of HBM memory and deliver 8 teraflops of compute power at a TDP of 200 watts.

That said, Jingjia Micro explains that it’s still in early development stages for the two graphics cards, which still have to go through more testing before the company can begin trial production runs. Efficiency is not a strong point of these, though performance is somewhat promising if they’re comparable — at least on paper — to GPUs from several years ago that are still fairly capable in the case of the GTX 1080. There’s also no word on DirectX or Vulkan API support, so it’s possible the JM9231 and JM9271 cards may never end up in a gaming PC.

Overall, it doesn’t look like China has made strides on this front yet despite pouring billions into subsidies for its semiconductor industry. Just as we’ve seen with the country’s CPU efforts, progress is slow, and few companies have the engineering know-how to pursue such projects.

The only other prominent companies known to be working on GPUs are Huawei’s HiSilicon subsidiary and Tianshu Zhixin Semiconductor, which are both working on GPGPUs for the Asian server market.

Mining – Recommended Products

Recommended for efficiency and ease of use, ideal for beginners but do your own research as always.

AMD GPUs

Sapphire Pulse AMD Radeon RX 6600 XT Gaming Graphics Card with 8GB GDDR6 –

AMD Motherboards

Great if you don’t want to shell out on a specialist board for more than 6 GPUs

This is the first in a series that I will post on GPU mining – remember to follow us on social media to keep in touch.

AMD GPU

If you would like to do some GPU mining as well look for a higher spec chip.

  • AMD Athlon 3000G 2-Core, 4-Thread Unlocked Desktop Processor with Radeon Graphics – Check out the choice page a great choice from multiple vendors.

PSUs

Server PSU

I would recommend for you to at least check out a server PSU – they are designed for long term use and are cheaper than ATX Power Supplies – with a ZFX board and Pico switch these can perform as a stand alone PSU – just remember to check your voltage as 120v will have a lower capacity on some units.

Mining Cases

For me when choosing a case its not really one model – it all depends on the amount of GPUs and you should choose accordingly.

Check out a selection and think what will fits the needs of the RIG you are building.

Cooling

Not to be overlooked cooling is very important but it also does not really matter about the price look for the airflow – if you like RGB go for it but personally I am staying away from them as they just attract moths etc.

  • Antec 120mm Case Fan, PC Case Fan High Performance, 3-pin Connector, PF12 Series 5 Packs

SSD / USB

This is another personal preference but I use hive OS so have found that a USB stick is sufficient and have not had a failure in 9 months with:-

RAM

I prefer not to cheap out on RAM and split a 16GB pack into 2 rigs.

OS

I personally use HiveOS – check them out simple and easy to use – plus you can see your Rigs anywhere!
