What the Core i7-2715QE is
Intel Core i7-2715QE is a quad core Sandy Bridge embedded processor that Intel released in January 2011 for soldered embedded boards. It runs at 2.1 GHz base with turbo to 3.0 GHz on one core and includes Hyper-Threading, so 4 cores give 8 threads. Cache is 6 MB Intel Smart Cache. Power is 45 W on a 32 nm process with 1,160 million transistors.
The QE suffix marks quad embedded with ECC memory and PCIe bifurcation on qualified carriers. Threaded control tasks use all 8 threads. Fixed carrier BOMs keep long life behavior stable.
Graphics are Intel HD Graphics 3000 at 650 MHz to 1200 MHz. The block drives embedded panels through carrier outputs. Memory is DDR3 with ECC in two channels.
Socket and motherboard compatibility
The Core i7-2715QE solders to BGA 1023 with 1,023 balls and cannot be moved. Embedded carriers qualify each board for fixed strings with long supply windows. Factory rework is the only way to change the chip.
The carrier BIOS must list the exact 2715QE string. The Socket vs chipset: what decides whether a CPU works guide covers list based pairing for embedded parts.
Memory, PCIe and cooling
Memory support is DDR3-1066 and 1333, two channels, up to 16 GB with ECC on embedded carriers. ECC catches single bit errors in always on service. Capacity follows the carrier design.
PCI Express lanes come from the CPU with bifurcation on qualified carriers for network, storage and expansion. Embedded boards spend lanes on reliable I/O rather than graphics slots.
Cooling is a 45 W embedded heatsink with directed airflow. The CPU cooler compatibility by socket guide notes soldered embedded cooling stays carrier specific.
Upgrade paths
There is no CPU upgrade path on soldered BGA 1023. The 2715QE cannot be removed, so more speed means a new carrier. A nearby socketed embedded quad is the 2710QE class on Socket G2.
A platform move to a current embedded package needs a new carrier and memory. Keep the 2715QE carrier for long life service.
Frequently asked questions
What socket does the Intel Core i7-2715QE use?
It uses BGA 1023, a soldered embedded package. The chip cannot be removed.
Does the Core i7-2715QE have Hyper-Threading?
Yes. Four cores give 8 threads.
What memory does the Core i7-2715QE use?
DDR3-1066 and 1333 with ECC on embedded carriers, two channels, up to 16 GB.
Can the Core i7-2715QE be upgraded?
No. A faster embedded box means a new carrier.
