Cray's XK7 Titan supercomputer is powered by no less than 18,000 Nvidia Tesla K20x GPUs, which Nvidia is proud to say highly contributes to make the Titan the world's fastest supercomputer. Today, the company is presenting a revised version of the graphics processor optimized for consumer tasks, and of course, gaming. Whoever said about the Titan "but can it play Crysis?", the joke is now on you.

The GeForce Titan specs are simply unheard of for a single GPU, boasting of 2688 CUDA cores versus the 1536 you find on a GTX 680, as well as packing 6GB 384-bit GDDR5 on board. In building this GPU, Nvidia says they faced a challenge of escalating performance without impacting efficiency and power consumption on the same proportion.

The company is playing this performance + efficiency card in two different ways: first for extreme gamers, the Titan is 3-way SLI capable. If the budget somehow allowed for such a luxury -- each card will run for about $899 -- there's a simple answer on how to build the fastest gaming PC ever if you throw three of these on a single machine. On the other hand, thermals and noise levels have been optimized, so Nvidia has been working with boutique PC builders (Origin, Falcon, Maingear, etc) to put the Titan inside small form factor PCs aimed at gamers. After all, a single one of these cards will push more frames than you can imagine.

Nvidia doesn't want us to talk about benchmark specifics for now, and there may be a good reason for it. On paper the Titan looks like a more elegant solution than the dual-GPU GTX 690 which fetches $999, but there's clearly the question of raw performance with a single card. Expect our full review of the GeForce Titan in the coming week or so.

Other interesting highlights about the Titan:

• The GeForce Titan will have fan control that includes voltage and RPM
• TDP rating is set at 250w vs. 300w on the GTX 690 and 195w on the GTX 680
• The Titan will ship with full performance double-precision compute

Just ahead of MWC 2013. Nvidia has announced a new mobile processor called Tegra 4i.

Aimed at the mainstream smartphone market, Nvidia believes the new chip will fill a gap in the company's offering. While Tegra 4's staple is higher end Android tablets, Tegra 4i (codenamed Grey, after Marvel's Jean Grey) is a processor very much designed for phones.

That's because it's at the lower end, performance-wise – and so cheaper - yet is still designed to support 1080p Full HD and 4G LTE capable handsets; a specially optimised version of the Nvidia i500 LTE modem is included in the design.

Like Tegra 3, it's based on ARM's older Cortex-A9 architecture (R4 A9) rather than the newer Cortex-A15 instruction set used for Tegra 4.

So you get 60 Nvidia GPU cores as opposed to Tegra 4's 72, but the same 4+1 core design as Tegra 3 and Tegra 4 is used, clocked at 2.3GHz - the fifth core is a battery saver core.

Better performance vs surface area

Nvidia is also shouting about the physical size of Tegra 4i's cores, saying that they are half the area (1.15mm2 vs 2.6mm2) of the competing Krait core from Qualcomm's Snapdragon S800 launched last month. It also claims that 4i beats even Tegra 4 in terms of performance per mm2.

Like Tegra 4, 4i also features Nvidia's Computational Photography Architecture, enabling advanced imaging features such as tap-to-track and HDR panoramics.

Nvidia has also announced a phone reference platform to showcase the design. Called Phoenix, it's 8mm thick, with 4G and a five-inch Full HD display.

As always with reference designs, Phoenix is designed to be a blueprint that phone makers can work with when designing and building Tegra 4i smartphones to help get them to market quicker.

Hopefully we'll see some handsets featuring Tegra 4i at MWC 2013 next week.

Nokia may be readying four new Windows Phone 8 handsets for MWC 2013 in Barcelona next week according to a serial tweeter.

We know Nokia has something up its sleeve for the event, but the Finnish firm hasn't given us any clues as to what it might be.

However according to @ailon, logs for US carrier Verizon has revealed four new handsets could be on the radar: "I see Nokia RM-914 (Lumia 520), RM-885 (Lumia 720), RM-887(?) and RM-860(?) on Verizon in our logs. 3-4 new phones at #MWC13?"

Two's a charm

Details on the Nokia Lumia 520 and Lumia 720 have already started doing the rounds, with the Lumia 520 expected to enter the market at the budget end with a 4-inch display, 1GHz dual-core processor, 512MB of RAM, 8GB internal storage and 5MP camera.

While the 520 will slide in under the Nokia Lumia 620, the Lumia 720 is expected to bridge the gap between that and the Lumia 820.

Reports suggest the Lumia 720 will sport a larger 4.3-inch display, the same processor, RAM and internal storage as the Lumia 520, with a 6MP camera round the back and a 2MP front-facing snapper, although it's not clear where these details have come from.

The RM-887 and RM-860 models are less clear cut. With no further details emerging for either device, some people believe that these may be variants of current handsets instead of being brand new phones.

There are rumours that Nokia is also prepping a flagship device, going by the codename Eos, which will feature the firm's 41MP camera which can be found on the 808 Pureview.

We'll be out in force at MWC 2013 next week to bring you all the latest from the show, so keep your eyes peeled for all the news from Nokia.

4G adoption in the UK hasn't been lightning fast for EE, the first network to make it available.

Britain's first 4G network launched at the end of October promising super-fast internet on the move, but its contracts came at an eye watering cost.

For all the advertising and various added extras which come with an EE 4G contract, uptake has been less than stellar with the network seeing 201,000 new postpaid customers added in the final quarter of 2012.

That figure represents both 3G and 4G contracts, so the firm's 4G uptake will be lower - a figure which isn't documented in the results.

The future's bright, and possibly cheaper

EE has an ambitious roll out plan in place and aims to have 98 per cent of the country covered by its 4G network by the end of this year, with 55 per cent of the UK population enjoying the super fast speeds by the end of June.

The network, which also oversees Orange and T-Mobile in the UK, may need to revisit its prices plans later this year when other networks launch rival 4G services.

Three has already announced its surprisingly affordable 4G plans for later this year, saying that its contracts won't cost any more than its current 3G tariffs - which would blow EE's pricing out of the water.

For the time being, though, EE has the 4G arena to itself and it will want to capitalise as much as possible before O2, Vodafone and Three enter the fray.
