Intel in fact only responsible for production of CPU, the application of the ULV CPU is no longer clearly defined limits , although designed to be battery life . But in fact , ULV CPU is generally regarded as Atom netbook and fill in the gap between conventional notebook products ,Acer Laptop Battery representing the light of this . Since AMD Yukon / Congo platforms appear , Intel Atom respond a bit stretched here , ULV CPU can actually fill this gap.
The current definition of ULV notebook mainly around 11 to 14 inch range , " light of this , Acer BATCL50L Battery,Acer Aspire One Battery, Acer TravelMate 290 Battery, " just to fill the netbook and notebook products that gap between . In fact do? Indeed, the low TDP bring low power and low heat , to a certain extent, the design can save space inside the notebook . The problem is , ULV Core size and mobility on the same chip set is the same , in the CPU and chipset size issue, there is little space-saving value.
With the technology , process improvement , cost reduction . 1 year ago in this 13-inch notebook with NV / ATI graphics core (including the remarkable and unique set of display) of the still very small , but now everywhere , shows progress on the technical process . Apple's 13.3 -inch this , almost all were using NV 's set , CPU , but with the P7450 and the like grade ; the SONY VAIO 13.3 -inch most of the current ATI 4570 alone were used , CPU with P8700, P8800 range . ASUS , Toshiba , DELL and so on cost performance is also known brands variety of 13.3 inches was the independence of this , many have used T series CPU.
So, from a performance / volume ratio point of view , ULV CPU and 13.3 of the conventional no advantage in this comparison , just any T series CPU 's performance more than ULV CPU, after all, the obvious difference in frequency in time is there for . ULV of the rest , and probably only a long life .
DELL Inspiron 1320-201
Compare the two notebooks Jingdong .Acer BATCL50L Battery, Take a look at DELL 's Inspiron 1320-201, ATI 4330 graphics card , T4300 CPU (2.1GHz frequency ), the nominal battery life 2 to 5 hours, nominal size : 322 218 27 ~ 31mm, nominal weight of 1.8kg . Year Inspiron 13Z-102, which is a ULV this , the other is basically the same configuration , CPU replaced with SU7300 (1.3GHz frequency ),Laptop batteryNominal battery life 11 hours , nominal size : 340 242.5 20.8 ~ 32.3mm, nominal weight of 2.01kg.
Can be out a little thinner though 13Z-102 , but the length and width and even increased. And 8 -coreLaptop battery, Thickness and weight even more than the 1320-201 . Therefore, if the data is not nominal Jingdong an error , DELL laptop this ULV compared with the conventional , time really is the only advantage of long life , account for less than what the volume really low weight . The T4300 and SU7300 , but the performance gap between the place where tomorrow 's .
Comparison of two specifications
Therefore , ULV notebook order to light , you have to give up a big heavy battery ; Acer BATCL50L Battery,Acer Aspire One Battery, Acer TravelMate 290 Battery, want life , we can not take the thin line, is facing a " Brokeback "situation . After all , CPU and chipset , like the volume , but low heat on low TDP from the design to save space . Moreover , ULV this is not so cheap , often similar configuration than conventional notebook also expensive , for example, the sophist Inspiron 13Z-102 price 5799 yuan , while the 1320-201 as long as 4,399 yuan .
durable than the thin , Atom dominant victory
Since 13.3 this size , ULV in the volume of the weight / performance ratio on the account for less than any advantage at all , leaving only the battery life of this advantage, 12.1 is a similar situation . Step back to 11.6,11.1 the following dimensions , it became a battlefield Atom netbooks , and the Internet to compare the volume of the weight , Acer Aspire One Battery, ULV this still really not much.
ION platform on such a small
The reason is obvious , Atom is designed for CPU, Core 2 Duo architecture and completely different , the interface is not the same chipset is not completely universal , Atom N270 design TDP only 2W, single -core ULV CPY of 5.5W can not compare . In the volume and heat on , Atom is dominant victory , as a separate product development , much smaller than the ULV CPU , and now a third-party vendors such as ION platform , has been related to the HTPC can do about palm-sized box . Broadly speaking, the light on this issue , Atom dominant victory , because the current ULV This product is concentrated in the 11.1,11.6,13.3,14 and so on, 8 -inch netbooks have . (This article is about as long as "the ", such as UX490N UMPC that is not using ULV CPU in the discussion )
