Last week we reported on that discovery Nvidia used a cutdown GA104 graphics processing unit (GPU) on the GeForce RTX 3060 A graphics card that is supposed to be based on the GA106 GPU. The “new” board has the same performance characteristics and power consumption as the “old” board. This week, two graphics card suppliers, Gainward and Galax, have listed the right products. This indicates that the GeForce RTX 3060 board with GA104 will be retailed.
China only.At this point
For now, Gainward and Galaxy only list GA104-150-based GeForce RTX 3060 graphics cards in China, so this version of the product could be yet another exclusive product for China. ..Meanwhile, previously Nvidia switched GPUs GeForce RTX 1650 When At least one GeForce RTX 2060 Being a model, it’s no surprise that Nvidia decides to use the GA104-150 for GeForce RTX 3060 boards sold elsewhere in the world.
Using a cutdown GA104 GPU for the GeForce RTX 3060 instead of GA106 only makes sense if the silicon is too defective to power the GeForce RTX 3060 Ti / 3070/3070 Ti graphics card. The GA104 is a fairly large 392 mm² chip with 17.4 billion transistors and up to 6144 CUDA cores, which is quite expensive to manufacture. In contrast, the GA106 is fairly inexpensive, 276 mm², and integrates 13.25 billion transistors and up to 3584 CUDA cores.
Chip developers like AMD and Nvidia usually try to sell batches of defective chips through OEMs and / or in certain markets because they are not easy to support (although some are not working). It works perfectly even if the unit is deactivated). Huge number of SKUs around the world.
If you still have a large number of dies that cannot work in the proper configuration due to defects, you need to invent a new model or reuse silicon for globally available low-end SKUs. It’s unclear if Nvidia has enough GA104 chips that can’t even be used with GeForce RTX 3060 Ti boards (with GPUs with 4864 CUDA cores), and the company needs to sell them outside of China.
Gainward has two (or four, depending on how you count) GeForce RTX 3060 12GB graphics cards that can be based on either GA106-300, GA106-302, or GA104-150. GeForce RTX OC / OCG With 3 fans GeForce RTX 3060 DU / DUG Features dual fan dual slot cooler as discovered by @momomo_us.. Gainward does not explicitly indicate this, but the letter “G” in the part number appears to indicate usage for the GA104-150 GPU.
Gainward’s close relatives, Galax, have four (or eight) GeForce RTX 3060 12GB add-in boards (AIBs) that may be based on either GA104 or GA106. GeForce RTX 3060 Gamer MAXOC[FG], NS GeForce RTX 3060 Golden Master MAXOC[FG], NS GeForce RTX 3060 Xing Yao MAX OC Forever Edition [FG], And that GeForce RTX 3060 MAX Xing Yao [FG], according to @momomo_us.. For Galax, the FG letter in the part number appears to indicate that the board is equipped with GA104, but it is not 100% certain because the vendor has not explicitly specified this.
The Gainward and Galax graphics boards use large printed circuit boards (PCBs), but I’m not sure if they use the same PCB for both the GA106 and GA104-based GeForce RTX 3060 12GB graphics cards. On the other hand, if the PCBs are the same, this means that Nvidia’s GA104 and GA106 are pin-to-pin compatible. Fortunately, at least the GeForce RTX 3060 AIB with GA106 and GA104 seem to have different part numbers.
A blessing in disguise?
For now, it’s hard to find a GeForce RTX 3060 with a GA104-150 GPU, but customers may be motivated to get these boards.
GA104 is considerably larger than GA106, but it is easy to cool to room temperature due to the large number of unused parts. This means that these parts can be a very good overclocker when compared to a regular GeForce RTX 3060 card with a GA106.
Still, overclockers need to keep in mind that overclocking potential also depends on the design and power supply of the PCB. On the other hand, the GeForce RTX 3060 AIB was designed to be cheap to build, so setting GPU frequency records wasn’t the goal engineers were trying to achieve with these products.
