We have recently spotted a large shipment of new boards, which are listed with GP106 GPU.
NVIDIA Pascal GP106
The decision to launch two Pascal GP104 boards with 8GB of memory generates a serious problem. The mid-range segment needs more memory, otherwise a large gap would appear in GeForce product portfolio. Since Polaris 10 is not even aiming at the same market, NVIDIA needs a competitive product with more than 4GB memory in 200-300 USD price range. It’s hard to say how fast GP106 could be, but if RX 480 is anywhere close to GP106 in terms of performance, then 4GB memory would definitely not look convincing to consumers. This means GeForce GTX 1060 needs 8GB or 6GB memory.
The latest shipment manifests we found could confirm just that.
The first listing shows E2914 board, which is an engineering sample with GP106 processor. According to this data, this sample would sport 6GB ‘GDD(5)’ memory:
E2914-A01 SKU0020 GP106 BRING-UP 6GB GDD FUNCTIONAL TEST PCA BOARDS, 699-12914-0020-100
The second listing could explain why there are 6GB models of GP106. It seems that GP106 could feature 192-bit memory bus:
PG410-A01 SKU0030 GP106 192B 128MX32 DP+ COMPUTER GRAPHICS CARDS, 699-1G410-0030-100
Interestingly, the memory size on PG410 board is 4GB. While both boards carry different numbers, they also have different SKUs (20 vs 30). The PG410 SKU 30 could be 4GB model, while SKU 20 would feature 6GB.
Of course this is just my theory, but there might be two GP106 products in the making (apart from PG418 board shown in Drive PX 2 module).
I think it’s safe to assume that one of them is GeForce GTX 1060. The other one could be mobile varaint or some fancy Ti model coming at later time, although Inno3D roadmap clearly mentions just one product:
