Intel's new processor

Intel this week unleashed a pair of new unlocked fourth-generation Core desktop chips code named Devil's Canyon, as well as a new unlocked Pentium processor.
The quad-core Intel Core i7 4790K has eight computing threads and a base clock speed of 4.0GHz which can be throttled up to 4.4GHz in Turbo mode. It has Intel HD 4600 graphics clocking at 1250MHz, 8MB of cache, supports two channels of DDR3-1600 memory, and draws 88 watts.
The quad-core Intel Core i5 4690K has four computing threads and a 3.5GHz base clock, which hits 3.9GHz in Turbo mode. This chip is also packing Intel HD 4600 graphics at a slightly lower frequency, 1200MHz. Also drawing 88W and supporting two channels of DDR3-1600 memory, the Core i5 4690K has 6MB of cache.
The Core i7 4790K is priced at $339 and the Core i5 4690K will set you back $242, slotting into the same price points as the older Core i7 4770K and Core i5 4670K, respectively. Both new processors will be available this month and drop into Intel's newly available, socket 1150-compatible 9 Series motherboards.Intel's 9 Series chipset supports both fourth-generation and fifth-generation Core processors. The new PC platform introduces Intel Rapid Storage Technology with Intel RST for PCIe Storage, providing "up to 67 percent" faster storage than than SATA Gen 3, according to the company, as well as Intel Device Protection Technology with Boot Guard.
The 9 Series chipset also carries over some key technologies from previous-generation platforms, such as Intel Small Business Advantage and PCI Express 2.0 at 5 GT/s, while providing high-speed SATA 6 Gb/s support for SSDs and HDDs, and integrated USB 3.0 in a "flexible" I/O port architecture, Intel said.
Intel OEM partners with Devil's Canyon-ready Series 9 boards ready to go include Gigabyte, Asus, ASRock, MSI, and EVGA.
The new Intel Pentium G3258 is priced at $72, slots into the Socket 1150, and lands in the Pentium family between the Pentium G3240 ($64) and the Pentium G3440 ($75). The Pentium G3258 is a dual-core, 3.2GHz part with two computing threads, 3MB of cache, and a 53W power draw. The new part supports dual-channel DDR3-1333 memory and packs in 1100 MHz Intel HD Graphics.
The Pentium G3258 is compatible with both Intel's 8 Series and 9 Series chipsets and is also being made available in June.

RASPBERRY PI

Raspberry  pi is single board computer in size of credit card which can be connected to TV and monitor. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python. It is capable of playing  HD     videos,playing games,browsing internet and making word processing and spreadsheet.

It can be used in a wide array of; 

• Digital maker projects.
•   Music machines.
•  Parent detectors.
•   Weather stations. 
•  Tweeting birdhouses with infra-red cameras.

Raspberry pi has three versions:

1. Raspberry pi model a.
2. Raspberry pi model b.
3. Raspberry pi model b+

Raspberry pi model a:

Model A is the lower-spec variant of the Raspberry Pi, with 256 MB of RAM, one USB port and no Ethernet port.

This model is usually bought for embedded projects: because it’s missing a few ports and an Ethernet chip, the Model A is lighter and consumes less power than a Model B. We see a lot of Model As used in robotics; and also in projects where weight and low power consumption is needed.

Specification:

Chip Broadcom BCM2835 SoC full HD multimedia applications processor

CPU 700 MHz Low Power ARM1176JZ-F Applications Processor

GPU Dual Core VideoCore IV® Multimedia Co-Processor

Memory 256MB SDRAM

Ethernet None

USB 2.0 Single USB Connector

Video Output HDMI (rev 1.3 & 1.4) Composite RCA

Audio Output 3.5mm jack, HDMI

Onboard Storage SD, MMC, SDIO card slot

Operating System Linux

Dimensions 8.6cm x 5.4cm x 1.5cm

Raspberry pi model b:

Model B is the higher-spec variant of the Raspberry Pi, with 512 MB of RAM, two USB ports and a 100mb Ethernet port. It’s our most popular model: you can use it to learn about computing; to power real-world projects (like home breweries, arcade machines, musical root vegetables, robot tanks and much more); as a web server; a bitcoin miner; or you can just use it to play Minecraft.

USB 2.0 double USB Connector

Video Output HDMI (rev 1.3 & 1.4) Composite RCA

Audio Output 3.5mm jack, HDMI

Onboard Storage SD, MMC, SDIO card slot

Raspberry pi model b+:

The Model B+ uses the same BCM2835 application processor as the Model B. It runs the same software, and still has 512MB RAM; but James and the team have made the following key improvements:

• More GPIO. The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model B.

• More USB. We now have 4 USB 2.0 ports, compared to 2 on the Model B, and better hotplug and overcurrent behaviour.

• Micro SD. The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version.

• Lower power consumption. By replacing linear regulators with switching ones we’ve reduced power consumption by between 0.5W and 1W.

• Better audio. The audio circuit incorporates a dedicated low-noise power supply.

Neater form factor. We’ve aligned the USB connectors with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes.
