I'm of the opinion that the 37W one should be avoided. One important consideration is whether to get a 37W i7-4702MQ (4-core turbo=2.9Ghz)to keep within the factory-configured CPU's TDP or get a faster and hotter 47W i7-4800QM/i7-4700MQ (4-core turbo=3.5/3.2Ghz). Upgraded E6440 i7-quad system examples are shown in the table above. I'd keep the original CPU back and swap it back in if necessary.

Note: warranty implications of a CPU upgrade - a factory-specced faster dual core up to i7-4610M will not void warranty while a i7-quad will void the warranty if Dell know about it as it wasn't offered with one. In fact, this slot is WLAN(PCIe1), mSATA (SATA3 port4) and WWAN (USB 2.0)!! Sharing the PCIe and SATA lines being a new Series-8 Flexible I/O chipset feature : Ĭan effectively double the CPU performance going from a factory i5/i7 dual core to a i7-quad CPU. It's situated above the WWAN marking as shown in the spoiler below. Yes, there is a mSATA slot in the E6440, though is not visible when taking the rear cover off.

14" 1080P or 900P is certainly more comfortable to use in a desktop space.

battery options include a 65Wh 6-cell, 97Wh 9-cell battery and 97Whr 9-cell clip-on slice via the docking connectorĬomparison: 14" Dell E6440 versus 12.5" HP 2570P (REF: ) E6440 betters the 2570P with it's 1080P or 900P LCD, mSATA option, SSHD, backlit keyboard and somewhat questionable better Haswell CPU and Series-8 chipset.

internal WWAN/3G capable : install a WWAN/3G, a mobile SIM and surf the internet anywhere.

backlit keyboard option: great for night time use.

upgradeable WLAN : non-whitelisted bios allows upgrading to 802.11AC WLAN with a Broadcom BCM4352 or Intel 7260 HMW card.

Or RAID-0 2xSSDs for superfast boot-times and > 1GB/s sequential transfers. Can have up to 5TB of internal HDD storage ( 2x2TB 9.5mm HDDs + 1TB mSATA SSD).

optical drive can be swapped with a second 2.5" 9.5mm SATA-III 6Gbps SSD or HDD in a caddy & in a JBOD, RAID-0 (performance) or RAID-1 (redundancy) configuration.

Then can use a larger internal HDD for storage.

mSATA (SATA-III) slot - can add a small and fast mSATA SSD to host your OS/programs.

E6440 systems specced without an expresscard slot can retrofit one at low cost.

rare 5Gbps expresscard slot allows implementing a ~$160 DIY eGPU for gaming graphics, CUDA/OpenCL processing or driving more external LCDs.

AMD HD8690M dGPU option, similar performance to a GT730M/GT640M and faster than the HD4600 iGPU.

Series-1 systemboards being dual-LVDs equipped capable of 1600x900.

1920x1080 eDP LCD option in latest E6440 to give more viewable content than the typically 1366x768.

The result of doing so being one of the smallest most powerful Haswell systems available that can function as a desktop replacement.

socketted CPU allows a easy user upgrade up to a 37W/47W i7-quad, doubling i5/i7 dual-core CPU performance.

Reasonable when you consider it's upgraded desktop-replacement performance and durable MIL-spec build in a portable 14" package. A E6440 can be had for ~US$400 on ebay-US.
