In the fast moving world of technology, it can become impossible to keep up with the ever changing landscape. This is why I have introduced this new series of posts to give you guys an idea of what is upcoming in the world of computers and whether it is worth the wait or better to just buy what is currently on offer. New technology also leads to price drops in the older (but not outdated) technology. For example, when Sandy Bridge processors from Intel came out, they offered a large jump in processing power as well as efficiency but laptops with the older generation of i5 and i7 could be found for $500-700, a far cry from the $1700 they were available for 6 months before. If you're willing to buy slightly older technology, the newer components can lead to massive savings for you especially as manufacturers and shops try to clear out their stocks. So what's new in the world of CPUs?

Intel

Intel is on the verge of releasing its new Ivy Bridge processors built on the 22nm architecture. They should by unveiled early next year and released soon after. It promises processors with more cores, more power and more efficiency than the previous generation as well as bringing 6 core processes to a more mainstream level (although still at the higher end). Obviously the high end will be well above $1000 but it should bring prices of existing Sandy Bridge processors down significantly. Sandy Bridge should be fine for the majority of people and is perfectly adequate for gaming as well. The potential cost savings are huge for those who want to build a cheap desktop or buy a new laptop. The advantages of upgrading to Ivy Bridge would be significant mainly for laptop users. The 22nm manufacturing process means less heat generated with more power. It should also be good news for overclockers especially due to the already high clock speeds and availability of multiplier unlocked processors.

AMD

AMD has already released their Bulldozer processors which includes the highest clock speed processor currently available however benchmarks have been disappointing. An interesting direction AMD seems to be taking is in launching Accelerated Processing Units (APUs) which aim to combine the roles of CPUs and graphics cards into one. This has the advantage of utilising the power of often unused graphics cards for everyday tasks. This also provides the benefit of lower power usage and less components in the system. This new concept will be of particular importance to laptops due to these key aspects. AMD is expected to replace its Bulldozer processors with the new Piledriver architecture in mid-late 2012. One key point about AMD processors is they are also significantly cheaper than Intel ones but offer similar performance. These soon to be released processors are capable of competing directly with both Sandy Bridge and Ivy Bridge processors from Intel and can be an excellent choice for those with a tight budget not looking to skimp on performance.

This is a brief summary of things to come in 2012. If you are considering building or buying a new computer, you might want to wait a few months for these new technologies to be released, either to have the latest and greatest or save a few bucks on the previous generation products. Please note that this information is based on leaked roadmaps and may not be 100% accurate, it is just meant to be used as a rough guide. The next post will cover motherboards.

Ever wanted to try and build your own computer or you just needed a new computer but couldn't afford one. Well, here are the specs for a well rounded system which has decent speed, the latest processor and is perfect for normal everyday use. With Intel HD graphics you can do a bit of video and photo editing but no games at this price. Of course, the motherboard is compatible with a video card so if you want to add a video card on later, it is possible. So not only is this system cheap, it is flexible and pretty powerful. All for under A$600.

All of the parts I have chosen are good quality and like I stated in the previous post, I have gone with a reputable case manufacturer. The other components are made by trusted brands. One potential downside is that to get it this cheap, I have had to use Linux instead of Windows. It is pretty good if you give it a go and it is free but some people absolutely must have Windows in which case the whole computer will cost another $150-250 extra depending on the version.

So if you are on a tight budget but are looking for a computer which will last you 2-3 years (depending on how much you hate having outdated components) and has a bit of flexibility for future upgrades, then consider a build like this.

Depending on the store you buy the parts from, you can also bargain and get it for even less. Try StaticIce to see if you are getting the best deal on your parts.

Today I thought I would talk about the advantages which smaller fabrication processes offer. All of the next gen chips are made on smaller and smaller processes. Intel has recently announced their 32nm fabrication process for the next generation processors. Nvidia has started manufacturing their latest GPUs on 55nm processes. So what does all this mean?

Smaller fabrication processes not only benefit the manufacturer but also the end user. They run much cooler and are more power efficient than older processes. If this isn't enough, even the costs come down significantly. An example of this is Intel's Wolfdale. Previously, an all round processsor would have been 2.4GHz and cost around $300. Intel released a 3.0GHz processor for $250 which was not only faster but it could be overclocked like no other processor and still run relatively cool. An Intel E8400 at 3.0GHz could be overclocked to 3.6GHz with no problems whereas previous Intel processors struggled to make such a speed jump without extra cooling.

This means that a 32nm processor will outshine a 45nm processor in everything. Speed, overclocking ability and cooling. Not only this but it will mean that not only gamers will have access to incredibly fast processors due to their affordable price. Anyone will be able to get a processor with a speed greater than 3.0GHz. The effect on Video Cards will be similar. Discrete graphics cards will not be limited to just users needing high performance. Not only this, but it adds the potential to easily build powerful graphics chips into motherboards as cooling will be less of a problem and it will take up less space. Currently Nvidia's latest graphics card, the GTX 295 is fast but it runs incredibly hot. It is impossible to run it in triple SLI with only air cooling. Part of the problem is the 65nm chip. This needs more power and runs very hot. In the future Graphics card manufacturers can fit similar performance in a smaller more accessible package. A smaller process also means more can be crammed onto the chip. As you can see from the above image, Intel is able to fit a graphics chip and memory controller into the processor now as well!

This is what these smaller fabrication processes mean. The advantages they give us are huge. Computers could be put in places you never thought possible. IBM is experimenting with chips right now using structures similar to DNA. This allows manufacturing processes as small as 22nm.

The new chip has graphics capability built into the core processor, a first for Intel, and has new Advanced Encryption Standard (AES) instructions also built in for faster encryption and decryption. The new chip will go into production in the fourth quarter of the year.

“The rapidly increasing number of transistors and processor instructions we add have made possible the integration of more and more capabilities and features within our processors,” he said.

“This has driven an incredible amount of innovation throughout the industry.”

Maloney will also be showing the Westmere-EP server platform and said that it would provide a performance boost greater than that seen with the introduction of the Xeon 5500 series of server chips over the previous generation.

Intel is also working on an ultra-low power server chip in the Xeon 3000 range, which will operate at just 30 watts.

As a follow up to Westmere the next generation chip, codenamed Sandy Bridge, will see an acceleration in graphics capabilities for the chip, with Intel's sixth generation graphics core built into the die. This will accelerate floating point, video and processor intensive software applications.

To help IT administrators Intel has developed a new PC management tool called Keyboard Video Mouse Remote Control, which allows managers to view problems directly as the user sees them, which it hopes will speed up fault solving.

SAN FRANCISCO (Reuters) - International Business Machines Corp is looking to the building blocks of our bodies -- DNA -- to be the structure of next-generation microchips.

As chipmakers compete to develop ever-smaller chips at cheaper prices, designers are struggling to cut costs.

Artificial DNA nanostructures, or "DNA origami" may provide a cheap framework on which to build tiny microchips, according to a paper published on Sunday in the journal Nature Nanotechnology.

Microchips are used in computers, cell phones and other electronic devices.

"This is the first demonstration of using biological molecules to help with processing in the semiconductor industry," IBM research manager Spike Narayan said in an interview with Reuters.

"Basically, this is telling us that biological structures like DNA actually offer some very reproducible, repetitive kinds of patterns that we can actually leverage in semiconductor processes," he said.
