Ago 20 years Finnish Prime Minister Harri Holkeri realised first call GSM (Global System for Mobile Comunication). In this historical call it used mobile in the area of frequencies 900MHz.

This moment the GSM is person in charge for communication 1. 5 billions of persons in 212 countries of serving him 80% of world mobile telephony!

the GSM measures today oyk few first-leads. Better quality of sound, card SIM (Subscriber Identity Module), roaming, SMS and technologies GPRS and Edge are certain only from them.

the GSM was extended in the areas of frequencies 400, 800, 1800 and 1900 MHZ, while afterwards it developed in UMTS (3G), later in HSPA and HSPA+ and today in LTE (4G) network.

Two decades before therefore, began the revolution of mobile telephony and we do not have than to we are grateful for all that we enjoy today and consider data!

a new 3D

As it was expected, Intel announced new processor of type LGA1366, which has the name Core i7-980. Is precisely similar in specifications with known Core i7-980X Extreme Edition but does not allocate xekleidoto multiplier.

Moreover, the ypersyndesmos QPI (QuickPath Interconnect) supports 4. 8GT/s and no 6. 4GT/s as in publication &amp? quot? Extreme Edition&amp? quot? . The new exapyrinos processor of Intel allocates frequency of operation 3. 33GHz (25x multiplier) makes use of technology HyperThreading (6-cores, 12-threads), 12MB L3 cache and TDP for 130W.

Naturally makes use of technology Turbo Boost, thanks to which the frequency of operation from 3. 33GHz is increased in the 3. 6GHz. It is manufactured in scale of completion 32nm and his cost it is $583.

the TUL Corporation announced via PowerColor and Vertex3D, new cards graphic that are based on the dual-GPU solution Radeon HD 6870 X2, but also Club 3D announced recently a such card graphic.

does

Club 3D Radeon HD 6870 X2 allocate in total 2240 stream processors while two GPUs of type &amp? quot? Barts&amp? quot? that it incorporates they have frequency of operation 900MHz while the incorporated memory of type GDDR5 demonstrates frequency of operation 4200MHz. The memory interface it has breadth 2 x 256-bit.

As long as it concerns in the exits, allocates two DVI, two mini-DisplayPort 1. a 2 and HDMI 1. 4.

the system of refrigeration of is type dual-slot, allocates two fans and five cupreous heatpipes. The cost of dual-GPU solution of Club 3D will be roughly $469. More you can read.

Prolimatech circulated a upgraded publication particularly popular psyktras Megahalems that brings moreover in her name the characterization Black Series, however should not you confuse him with Mega Shadow that ceased it circulates.

Prolimatech Megahalems Black Edition allocates similar specifications with Megahalems Rev. B as as an example they are dimensions (158,7 x 130 x 74mm), the six epinikelomenoi heatpipes (thickness 6mm) form &amp? quot? U&amp? quot? or the provision with the two &amp? quot? pyrgoys&amp? quot? .

news Megahalems Black Edition however does not allocate epinikelomena made of aluminium fins, but allocates a coating - rather from ceramic material as what we observe in motherboard the ASUS of line of TUF - that increases the thermoapagogiki surface.

So much the base what heatpipes, even if epinikelothei they have they have been manufactured by coper. Her weight is 800 grams.

news Megahalems Black Edition is compatible so much with socket Intel, LGA775, 1155, 1156, 1366 what with socket the AMD, AM3+, AM3, AM2+ and AM2. The fans are optional, and accept until 2 x 120mm or 2 x 140mm. .

See one relative video that they prepared in Caseking. de however in order to you occupy what they say it will be supposed you know German.

Gigabyte, noiseless, circulated news, second publication of known GV-N560SO-1GI-950 (her commercial name is Geforce GTX 560 Ti Super Overclock).

H rev. 2. 0 GV-N560SO-1GI-950 it allocates precisely same chronismoys with rev. 1. 0 model (which you can you see here), but as you can observe also in the picture following, it allocates new planning in the system of refrigeration with two fans of 100mm.

At the other, allocates planning Ultra Durable VGA+ 2oz copper PCB, Japanese solid capacitors, Ferrite Core chokes, low (RDS) MOSFETs and Proadlizer and Geforce GTX 560 GPU that are based incorporate 384 cores CUDA dragged on in 1900MHz. The GPU allocates chronismo 950MHz while the memory, size of 1GB chronizetai in 4580MHz.

the breadth memory interface is 256-bit. Are the exits of type dual-DVI and mini-HDMI and her cost isn’t expected to be differentiated very concerning the first publication, that is to say it will oscillate near the &amp? euro? 230. More you can read.
