What the Nano QuadCore C4650 is

The Nano QuadCore C4650 is a 28 nm VIA embedded quad core on VIA NanoBGA2 for fanless x86 controllers. It runs 4 Isaiah II cores and 4 threads at 1.333 GHz base with bursts to 2.0 GHz. Two megabytes of shared L2 cache cover control loops. Power is 18 W with September 2015 availability through embedded channels.

Four real cores with PadLock AES acceleration suit firewalls and thin clients that need x86 software. The 333 MHz base clock with a 4x multiplier keeps idle draw low. TSMC manufactures the 46 mm2 die. The locked multiplier keeps behavior steady in sealed boxes.

Memory is single channel DDR3-1333 with about 10.7 GB/s. Graphics where needed is a VX900 or VX11 chipset feature rather than on die silicon. Buyers pick the C4650 where VIA supply and PadLock matter more than raw speed.

Socket and motherboard compatibility

The C4650 solders to VIA NanoBGA2 at 21 × 21 mm with 400 balls. No socket and no later swap exist. Embedded vendors validate the board with its VX900 or VX11 companion chipset for display outputs. The socket chipset table covers this CNR codename.

Single channel DDR3 is a hard platform limit. The LGA, PGA and BGA: CPU package types explained guide explains soldered embedded design. Confirm display outputs per board, since the CPU carries none.

Memory, PCIe and cooling

DDR3-1333 over one 64 bit channel feeds four cores with modest bandwidth. Size the single memory channel for the whole control workload. ECC is not offered.

The CPU bus runs at 1333 MHz to the companion chipset, and PCIe plus display I/O hang off that chip. Compact flash or small SSDs suit the bandwidth. Check lane counts per board before adding cards.

Cooling uses low profile embedded heatsinks for 18 W. Fanless operation suits dusty cabinets. The locked multiplier keeps thermals predictable.

Upgrade paths

No CPU upgrade exists on soldered nanoBGA2. The VIA Nano QuadCore C4700 at the same clocks on the same package is the only lateral option, chosen by availability rather than speed. Both share boards and chipsets.

A new platform means a new board. The How to find your CPU socket type guide helps identify soldered VIA systems.
