What the Core i7-6785R is
The Core i7-6785R brings Skylake to BGA 1440 for compact desktops with Iris Pro graphics. It launched in May 2016 with a 3.3 GHz base and up to 3.9 GHz boost at 65 W. Intel targets AIO bodies that need four cores with fast graphics and no socket.
Eight megabytes of Smart Cache carry office work and creation without eDRAM wait. The high base clock keeps apps responsive. Eight threads cover foreground tasks plus background services.
Iris Pro Graphics 580 with 128 MB eDRAM drive panels and external monitors. The process is 14 nm. The multiplier is locked. DDR4-2133 and DDR3L-1600 in two channels feed CPU and graphics.
Buyers choose the board at order time with memory size and display tier. The 65 W rating suits slim AIO chassis with tuned airflow. A 100 C junction limit guides thermal design.
Socket and motherboard compatibility
The Core i7-6785R is soldered to the board on BGA 1440 and cannot be replaced. Upgrading means replacing the board or the whole device, so choose memory and graphics at purchase. Boards pair the chip with SODIMM slots and eDP for panels.
BGA 1440 boards wire PCIe, SATA and USB per compact design. LGA 1151 desktops cannot take this BGA chip. The LGA, PGA and BGA: CPU package types explained guide explains soldered packages.
Single socket compacts are the deployment. Growth means another BGA 1440 device rather than a chip swap. Service follows the maker manual.
Memory, PCIe and cooling
DDR4-2133 and DDR3L-1600 in two channels suit compact desktops with SSDs. Matched pairs help Iris Pro graphics. Start with 8 GB for office use.
PCIe 3.0 with 16 lanes from the CPU serves NVMe and board devices. Most builds rely on Iris Pro and skip discrete graphics. Chipset lanes add extra storage.
Cooling has no retail mount pattern because the chip is soldered. Vendors design heat pipes for 65 W classes. Keep vents clear where units run daily. ECC is not supported.
Upgrade paths
On the same package, the Intel Core i5-6350HQ drops to four threads at 45 W for notebooks with similar graphics. Kaby Lake-H i7-7700HQ parts move later notebooks to higher clocks where listed. Both share BGA 1440 boards but differ in power.
LGA 1151 i7-6700 gives socketed desktops similar cores with HD 530. It requires a different board.
Past BGA 1440 compacts move to Coffee Lake-H or Comet Lake-H. The i7-6785R covers 2016 AIO bodies where four cores with Iris Pro must run at 65 W.
