A new picture has reveal NVIDIA GP104 “Pascal” ASIC surrounded with GDDR5X memory chips, which may indicate the possibility of NVIDIA reserving the new fast memory standard for the GTX 1080, and older GDDR5 for the more affordable GTX 1070. The new picture also reveals a GP104 chip with the ASIC code “GP104-400-A1,” surrounded by eight Micron-made GDDR5X memory chips. We know from an older article that this ASIC code denotes the top-tier GTX 1080. Few days ago another picture was revealed “GP104-200-A1” ASIC surrounded by conventional GDDR5 memory chips. This means GP104-200-A1 may be the GTX 1070 with GDDR5.
GDDR5 and GDDR5X are almost identical electrically, and the GP104 chip’s memory controller can supports both GDDR5 and GDDR5X. The GDDR5 have speeds of up to 8 Gbps, while GDDR5X chips can support up-to 14 Gbps. NVIDIA’s new cards may launch June, beginning with the GTX 1080 and GTX 1070.
