The specification compared with Raspberry Pi Model B is shown below
||Raspberry Pi 2 Model B
||123.8 mm (L) × 72.0 mm (W).USB connectors, RJ45 jack, and power jack slightly extend beyond these dimensions. Larger than Galileo Gen 1.
||85.60mm x 56mm x 21mm (with a little overlap for SD card )Same size as RPi 1, Model B, with same 4 mounting hole sizes & locations.
||Intel® Quark X1000 – single core
||BCM2836 (ARMv7) – Quad Core
|Description of Processor
||Quark, described by Intel at IDF2013, is very low power consumption, small form factor, and low cost; ideal for “wearables,” and the Internet of Things†.
||BCM2836 is a power efficient, full HD, multimedia applications processor for media playback, imaging, camcorder, streaming media, graphics and 3D gaming.
||Intel ® Pentium® Class
||ARM® Cortex-A7 ARM1176JZ-F
|Width, Instruction Set
|Real Time Clock
||Yes, needs a 3.3v coin cell
||16 KB L1 cache
||Dedicated 512 KB CPU cache
||512KB on-chip SRAM & 256MB DRAM
||1GB LPDDR2 SDRAM
||8MB NOR Flash for FW bootloader & sketch storage
||No permanent on-board Flash memory.
||No, but Pi 2 easily accommodates an external EEPROM.
||Broadcom Dual Core VideoCore IV® Multimedia Co-Processor
||Micro-SD Card (up to 32GB), & support for an external USB2.0 drive
||Micro-SD-card, & support for an external USB2.0 drive
||HDMI w/HDPC at 1080p60-Full HD 3.5mm composite video (and audio) jack DSI* – for touchscreens
