What Are The Benefits Of Mobile Dual-Core Processors?

When browsing through different notebook computer models, you are guaranteed to encounter the "Intel Core 2 Duo" or the "AMD Turion 64 x2" labels. These labels indicate dual-core processing technology for mobile computing. Multi-core processing is the buzz-word of the day, but what does it mean for you?

Mobile Dual-Core Processors

Mobile dual-core processors refer to a processor system consisting of two independent processor cores combined in one integrated circuit (IC) or, as industry professionals say, in a single die. Basically, mobile dual-core processors place two central processing unit (CPU) cores in one processor. Dual-core processing was first applied to desktop computing and home console gaming, but it was quickly adapted for mobile computing. As expected, AMD and Intel both have numerous mobile dual-core processing options available.

Dual-core processors have a different architecture than twin- or double-core processors. Dual-core processors refer to a processing system where two processors are integrated in one IC die. On the other hand, twin-core processors refer to a processing system where two independent processors - each on its own die - are directly plugged into the motherboard.

Each of the processors in a dual-core processor has a built in cache (Level 1 cache) so each has its own potential for speedy and efficient recovery and processing of frequently used instructions. More than that, however, there is a Level 2 cache, in the same IC board, which the two processors share in Intel's Mobile Core 2 Duo chipsets (either 2 or 4 MB); In AMD's Turion 64 x2 chipsets, each of the two processor has a dedicated 512 kb cache per core. The L2 cache is the processor's backup cache in case the L1 cache is not enough.

The Benefits of Mobile Dual-Core Processing

The foremost advantages of dual-core processors are speed and efficiency. Instruction processing and data retrieval are handled by two processors, so more processing speed can be achieved without overheating either processor. The fact that the two processors have their own easily accessible L1 cache also assures more speed. Furthermore, especially in the case of the Intel Core 2 Duo where the L2 cache is shared, full L2 cache memory can be quickly utilized by either one or both processors as the need arises.

In a nutshell, a notebook computer which has a dual-core processor is assured of fast and efficient processing performance with a greatly reduced risk of overheating. Multi-tasking is much improved. Dual-core processors also consume less power than twin-core processors.

One other benefit of dual-core processors in notebook computers is the possibility of lighter and smaller notebooks that can approximate desktop PC performance. Since two processors share one IC die, one can enjoy the benefits of dual-CPU processing without having to deal with extra bulk.

It is important to note that users of older programs will not see any benefit from their dual-core processors if they only run one program at a time. Older programs were not designed for dual-core processing, so they are only able to take advantage of a single core. A dual-core processor still gives considerable advantages in multi-tasking, however, as each core is able to handle a different program, speeding up multi-tasking considerably when compared to a single-core computer.

As time goes on, more and more software developers are developing their products with dual-core processors in mind, so users will see more and more benefit out of their dual-core processors in the near future.

Asus Eee Computer 1015PEM Dual Core Mini Netbook Reviewed

The Asus Eee 1015 PEM may be the 10 inch netbook from Asus using a dual core Atom N550 processor. Physically, the laptop is virtually identical on the Eee Pc 1015PED that I’m reviewing, using the very same seashell-style situation, chiclet keyboard, and matte touchpad. But though the 1015PED features a single core CPU, the Eee Computer 1015PEM will get a dual core improve. Obviously that does not imply it is twice as quickly, nonetheless it will need to be not less than just a little more potent.

Laptop Magazine is probably the 1st institutions to put that theory for the check, that has a in depth examine. The Asus 1015 PEM reportedly bested the Acer Aspire One particular D255 in some benchmarks, though equally netbooks have the exact CPU. It also arrives out way ahead of a normal single core netbook. The laptop also managed to transcode a video clip file about two minutes faster than a common netbook.

On the other hand, it looks like you must only assume about a 20 percent efficiency increase in overall computing duties, along with the Eee Computer 1015PEM has common Intel GMA 3150 integrated graphics. When that ought to be very good ample for handling 720p HD video clip, really don't be expecting to watch 1080p motion pictures or play bleeding edge video clip games on this procedure. HD Flash video also appeared to give the laptop some issues.

The good: Lengthy battery life; dual-core Atom processor gives you superior multitasking speeds; cost for a dual-core Atom configuration is not a lot more than for the single-core alternate.

The lousy: Cramped keyboard; streaming full-screen videos do not glimpse much greater than on single-core Atom Netbooks; lacks HD screen and HD accelerated graphics.

The bottom line: For only a slight selling price raise over its single-core cousins, the Asus Eee Computer 1015PEM's dual-core Atom CPU handles multitasking improved, but this Netbook does not present the attributes or efficiency we have seen in higher-priced "premium" alternatives.
Assessment:

Not very much has adjusted in Netbooks due to the fact next-gen Atom N450 processors hit the scene in the starting of 2010, that is why the emergence of dual-core Atom Netbooks merits some curiosity. Single-core Netbooks have usually lacked the oomph to attack tasks the way in which a full-size laptop computer can, specifically in relation to multitasking. The dual-core Atom N550 CPU while in the Asus 1015 PEM offers slight efficiency improvements devoid of leading to any added strain on battery life or your wallet; this configuration costs about $40 more than an otherwise comparable single-core Asus Eee Computer 1015PED with an Atom N455 CPU.

How much is my music computer worth?

I have a custom built computer for music production and now I'm thinking about parting with it.... How much is this computer worth nowadays? I also have a TC Electronic Powercore MK2 installed which I would leave in...

Specs:
Carillon AC-1X with a dual xeon processor - full spec - AC-1X+
Dual Xeon 3.4G CPUs, iWill DH800 Xeon motherboard, Radeon 9200/128MB Graphics Card, 2048MB DDR RAM, 200GB IDE Drive, 800GB SATA RAID (2 x 400GB), DVDR/RW, Windows XP Pro, Extra 6 USB and 3 FW ports (PCI card), TC Electronic Powercore mk2

So.... How much would this computer be worth today??

Cheers!

You know, you can very easily take it to your nearest computer store, such as pc world. comet etc. By asking them retail price while they examine at they can say the price that it can be sold for, depending on the state of the components and how new they are. They can easily say how much you should sell it for, either to a person or simply sell it for parts and/or on certain websites. But, most people are looking for good/very good graphics cards, since you said its for music purpose I'd propably say that is worth about £400-900. Judging by those components that you said.

RIM reveals BlackBerry Bold 9790, Curve 9380; launching in coming weeks (The Boy Genius Report)

RIM unveiled two brand new BlackBerry 7 devices on Tuesday: the BlackBerry
Bold 9790 and the BlackBerry Curve 9380. The Bold 9790 is equipped with a 1GHz
processor, a 2.44-inch touchscreen display with a 480 x 360-pixel resolution,
support for near-field communications (NFC), 8GB of storage and a full QWERTY
keyboard. Much like the Torch 9850/9860, the Curve 9380 offers a 3.2-inch full
touchscreen display with a 480 x 360-pixel resolution, NFC support and a
5-megapixel camera. The phones offer such minute updates to RIM's existing
portfolio of phones that we're really not quite sure why they need to exist,
but RIM says they will be available from a number of carriers around the globe
in the coming weeks. Read
