Jingjia Micro Tapes Out JM9-Series GPUs, Aiming for GTX 1080 Performance

China-based Jingjia Micro has taped out its next-generation JM9 graphics processing units. The new GPUs will reportedly offer performance comparable to that of Nvidia's GeForce GTX 10-series 'Pascal' GPUs launched in 2016. The new GPUs will hit the market sometime next year. 

Jingjia Micro's JM9 family consists of two GPUs: the entry-level JM9231 featuring a 2 FP32 TFLOPS performance at 150W and the higher-end JM9271 that offers FP32 performance of around 8 TFLOPS at 200W. Graphics cards based on the JM9231 will be equipped with 8GB of GDDR5 memory, whereas boards featuring the JM9271 will come with 16GB of HBM memory.  

The GPU developer from China has been talking about its JM9 GPU family since at least 2019, so the family is clearly late to the market, as the company taped out the chips only recently, according to a report from MyDrivers (via VideoCardz). Typically, it takes a year for GPUs to enter mass production after the initial tape out if the chip works as planned, so don't expect JM9-based graphics cards to hit the market before fall 2022.

Offering performance of Nvidia's 2016 GPUs in 2022 will hardly make Jingjia Micro a leading supplier of GPUs, but the company works with the Chinese government and supplies graphics chips for applications like military aircraft (and probably their simulators), so expect Jingjia Micro to sell quite a lot of its GPUs to its traditional customers that supply PCs to various government-controlled organizations.  

It remains to be seen whether the company will also sell its JM9271 to gamers, though. The chip uses HBM memory and boasts a 512GBps memory bandwidth, which is higher than that featured by Nvidia's GeForce GTX 1080. At the same time, use of HBM memory makes the JM9271 more expensive than most contemporary gaming GPUs, so its success against offerings from AMD and Nvidia is not guaranteed.

    While no longer cutting edge a GTX 1080 is still a very capable GPU, I can see many applications for another GPU with similar performance, complete with an official Chinese government snoopy prize :)

    It is unlikely to be sold outside china
    The performance leap in one generation is massive ( GeForce GT 640 (JM7200's) performance to a 1080) colour me surprised if this is true.

    hey, even if you "acquire" the blueprints, it still takes time & effort to actually manufacture the knock-offs. ;)

    beign china they likely reverse engineer others gpu's to take shortcuts (i mean they are known to steal tech publicly)

    I would not have believed they could reverse engineer the 1080 so fast, (or what ever card they copied the tech from). But it will have the Government Mandated back door in its firmware. It could help to push other graphics designers to accelerate their advances.

    Its a pretty common thing even among US companies to see how your competitor does something, doesnt mean youll copy it exactly, but it might give you some ideas to look elsewhere or tweak your own designs. The problem with China is they have tended to just straight up copy, often without a firm grasp of the underlying engineering, so they find themselves kind of stuck in a continual cycle of copying to get better tech, granted thats been changing recently, but its still their recent past. Honestly they wouldnt be the first country to get a jump start like that, Japan and South Korea got started on their tech runs in the same way. As for the back doors, yeahhhh they're still pretty obvious about how they implement those, spectre and meltdown took a while to be discovered :LOL:.

    No DX12 support? No thanks. Especially considering the origin.
    NVIDIA and AMD are at least reputable and here to stay. Nvidia (and AMD) provide frequent software, drivers, updates, notes. This should be more than enough reasons NOT to purchase these jangjin knock-off cards and rather stick to what is solid and safe.

    I wanna see them create an NVIDIA Ansel knock-off, then they can be even considered worthy to be disqualified thereafter.
