Dell XPS 8500


This $1,999 XPS 8500 embodies a familiar problem for Dell. It wants to perpetuate its high-end desktop range, but its mainstream configurations keep it from offering good performance value. Dell does make effective use of a fast storage access technology from Intel in this PC. A fat 3TB hard drive may also hold appeal. Those features are welcome, but too many PCs from smaller, speed-oriented vendors surpass the XPS 8500 in application and gaming performance. If you agree that raw horsepower is the primary reason for the continued existence of expensive midtower desktops, it's hard to recommend the XPS 8500 over its competition.
Dell has used the XPS 8000-series tower design since 2009. It continues to offer a clean, unique look, although Dell has streamlined this newest model. Where previously Dell hid the front-panel USB and audio ports behind a finicky plastic cover, now the USB ports simply sit, uncovered, on the front of the unit. They're a minor disruption to the XPS 8500's aesthetics, but the benefit of easier access makes up for it.
In terms of its configuration, the XPS 8500 is based on Intel's new, third-generation Core i7 chips, aka Ivy Bridge. The new chips offer few performance gains over the older, second-generation Core i7 family. Their primary advantages are updated embedded graphics technology and better power efficiency because of a more efficient manufacturing process.
The embedded graphics cores bring longed-for 3D gaming capability to lower-end systems, but in PCs like this one that have discrete graphics cards, the embedded video core in the CPU doesn't have much to do. Greater power efficiency is nice, and a necessary step on the way to faster chips in the next generation, but it's not the most compelling selling point for consumers.
Intel also introduced a new motherboard chipset with its new CPU. One of the best features of the Intel H77 circuity is that it brings Intel's Smart Response Technology to more-affordable motherboards than when it debuted on the Z68 chipsets.
Smart Response Technology (SRT) enables vendors to connect a solid-state drive (SSD) directly to the motherboard. The drive then acts as a standalone drive partition that provides faster boot time and speedier access to your most commonly used files. Maingear sent in the first system I ever saw with an SRT drive a few months ago in a Z68 board. Dell is the first vendor to send in a system with SRT via H77, enabled here in the form of a 256GB mSATA solid-state drive.
To get an idea of the benefits of an SRT hard drive, I tested the Dell XPS 8500's boot time against that of the Origin Genesis, a $3,399 system with two standard SSDs as its primary partition.
Dell XPS 8500 boot time (three-run average): 34.8 seconds
Origin Genesis boot time (three-run average): 39.93 seconds
The XPS 8500 boots fast enough that you will notice, and it's a great feature. The problem is that this system lacks the general processing punch I expect from a $1,999 desktop.

Its price puts the Dell XPS 8500 between two recent Editors' Choice Award-winning desktops, the $2,299 Velocity Micro Edge Z55 and the $1,199 Origin Chronos. The Origin system provides a bigger price gap, and is ultimately the system that's most damning for this Dell.
Per usual, Dell loses the performance competition because it does not offer overclocked processors. Both Origin and Velocity Micro do. Those systems don't defeat the Dell on every performance test, but they win more often and arguably on the most important benchmarks.
If you want to take a more holistic view of the Dell's relative value, you might suggest that the onboard SSD and the massive 3TB storage drive make up for what the Dell lacks in speed with faster file access and boot times, as well as more storage capacity.
I would argue against that assessment. Hard drives that are 3TB aren't terribly exotic. You can find them for less than $200; mSATA SSD hard drives are more expensive. A 256GB model like the one in the Dell will run you about $500 to $600 purchased at retail. Perhaps that accounts for the Dell having a higher price than the Origin, but I'm not sure that's the best way to spend $600 on a PC component.
You could spend $300 and see generally faster (or at least, as fast) boot and file speeds with a standard 256GB SSD, for example. A 128GB mSATA SSD also goes for about $300, and would offer similar performance but with only marginally less storage space. It's a moot point since you can no longer configure internal hardware components on Dell's Web site. That means, at least for this high-end XPS 8500 build, you're stuck with the 256GB mSATA and its heavy cost burden.
The extra boot and file access speeds are useful, but they primarily benefit you during occasional wait times for file or level loading. As prices drop, I expect we'll see more systems with onboard SSDs like that in the XPS 8500. Until they do, bear in mind that raw processing horsepower has a bigger impact on the overall user experience, particularly for the gamers most likely to buy desktops like this one.Premium 64-bit; 4.9GHz Intel Core i7-2700K (overclocked); 8GB 1,333MHz DDR3 SDRAM; (2)1.28GB Nvidia GeForce GTX 560 Ti graphics cards; (2) 60GB Int1.82

How to make an external laptop graphics adaptor



How to make an external laptop graphics adaptor
Give your laptop some gaming power


 Take a spare 3D graphics card and hook it up to your laptop



Laptop graphics have always been something of a joke performance wise. Nvidia and AMD do try, but cramming all those millions of transistors into a low-power, compact package just leads to massive expense and an inability to upgrade.
Wouldn't it be perfect if you could simply use a standard external graphics card to power your laptop's 3D graphics?
The good news is that you can. The suitably technical-sounding PE4H is just that; a passive PCI-e x16 to x1 adaptor, which enables you to plug an external graphics card into a laptop's ExpressCard slot. Currently we're only aware of it being available from the Taiwanese firm www.hwtools.net for around $100 including shipping.
We'd like to say it's as simple as that, but this project does have a few sticking points. The first we've already mentioned: a laptop with an ExpressCard slot.
The second is Windows 7, as it handles multiple display drivers far more adeptly than anything else. We're told Windows XP is next best with Vista being least desirable.
Also if your laptop has more than 2GB of memory a 64-bit installation is also required, as otherwise you'll hit the 4GB address space limit hard. The big issue here is that it'll cause the allocation of memory for the graphics card to fail.
Even though the card has its own memory the processor still needs to be able to address it, this address space is added on top of any existing system memory plus any other hardware resources, including the integrated graphics memory space.
The final sticking point is that there are certain laptop models that this simply won't work with or have some serious documented issues. Some of these can be worked around and others cannot, but before you run off and spend your money it's best to check if people have reported issues with your model.
The best two sources for compatibility can be found on the Notebook Review forum and Village Tronic. The former is the best, offering detailed system configuration and how many issues are solved.
The PE4H comes with the adaptor itself, an ExpressCard, data cable, Molex power cable and ATX power switch. Alongside this you'll need a suitable power supply, the adaptor can take a 12 to 15v supply but for higher-end cards you'll need a desktop PSU anyway. Plus for neatness we're going to house it all inside a mini-barebones case.

PE4H

The walkthrough below details putting together a system. The main thing to be aware of is before plugging the ExpressCard into the laptop, you will need to have Windows fully booted and to have the graphics card powered up. It's important to do this so Windows can recognise and install the correct drivers. If everything goes smoothly you'll have multi-card, multi-monitor system, where there was none before.
This might not be evident but it has happened, check the Display Properties Control Panel to see if the new display is detected and active.
Troubleshooting
In our case we encountered a couple of issues on our Lenovo X200 at this stage, which we can see other people encountering. If the card isn't detected reboot and see how the BIOS handles the new device.
For us booting produced a stream of POST errors complaining about PCI resource allocation problems. A BIOS update later and we had a booting system but one that was running incredibly slowly.
Our next step was to try inserting the card immediately after pressing the power button and that seemed to sort this out. Similarly another trick is to put the laptop to sleep insert the card and power back up. Whatever voodoo cured the problem, once it was up and running we didn't have any further problems and the device could be happily hot swapped. All of these issues are connected to allocation of the PCI address space for the card.
Once it's up and running it just works, albeit within the limitations of a x1 PCI-e system. You may have spotted that the adaptor card offers four PCI-e connections, the obvious question is how do you connect those additional PCI-e lanes?
Most laptops use a mini-PCI-e add-in card for its wireless adaptor, other laptops actually have spare mini-PCI-e ports for 3G modems and the like. If you can locate one of these and add-in one of the HWTool PM3N mini-PCI-e adaptors, then it's possible to upgrade to an x2 system where the performance hit narrows to around 75 percent of the graphic card's full performance.
This, of course, requires a second cable to be trailed from the laptop to the adaptor, as it turns out these are mini HDMI (Type-C) cables, so can be picked up from various sources such as www.lindy.com.
Use something like SiSoft Sandra to see what chipset your laptop has and what devices are attached to them, the Hardware Buses report tool is best. The older ICH6/7M Southbridge can provide up to four PCI-e ports. The newer ICH8/9M and HM55 chipsets can go to six, with the latest HM/QM/QS57 range providing up to eight. You need to use the ports in matched pairs for it to work, so ports one and two or three and four.
DIY desktop graphics for your notebook
We remember getting excited about an Asus prototype called the XG Station a few years back at Computex in Taipei. That device promised to do something similar to this project. It never made it to the UK though, but did pop up in Australia in 2008 before promptly disappearing within a year.
No matter, we'll show you how to hook up your own spare PCI-e graphics card to your laptop. It just takes the right bits of hardware and an ExpressCard equipped laptop. We're even going to look at an easy way to package the whole lot into an external case.
1. The kit you will need to make your adaptor

step 1

The catchy named PE4H from www.hwtools.net comes with a x16 PCI-e adaptor, the ExpressCard interface, an ATX power switch, plus the necessary Molex power cable and PCI Express data cable.
2. Grab a passive PCI Express adaptor

step 2

The adaptor that takes the PCI Express graphics card is called a passive adaptor, which is actually not doing any processing or routing, it's simply connecting two buses together.
3. Connect the GPU to the ExpressCard

step 3

Getting started is easy enough, plug the graphics card into the adaptor and connect the data cable to the first PCI-e port and to the ExpressCard, not forgetting the power cable.
4. Get a PSU powering your graphics card

step 4

So you can use a standard PC system power supply for your graphics card an ATX power adaptor is supplied, which will attach to the 20/24-pin power cable of the PSU.
5. Everything hooked up and ready to go

step 5

With a basic PCI Express graphics card the set-up looks a little like this (with or without a loop in the cable). At this point you don't want to connect the ExpressCard but you can boot your laptop.
6. Now, power up the pixel pusher

step 6

Before you go ahead and connect the ExpressCard to your laptop, you must make sure that the graphics card is powered up, so turn on the ATX switch and power up the PSU.
7. Get in on some ExpressCard action

step 7

With your Windows OS laptop up and running along with external graphics card, you can now safely push the ExpressCard into its slot, being careful not to knock over the graphics card in the process!
8. Displays ahoy, as far as the eye can see

step 8

If you have a compatible laptop, then after a flicker or two and perhaps a reboot, the laptop should detect the new graphics card and automatically start installing the driver.
9. Control, multimonitor is a go

step 9

If everything has worked correctly then you will now have a multimonitor system that you can configure from the Windows Display Control Panel.
10. Put her safe 'n' sound in the mini

step 10

To create a neat external box, we're going to cheat a little and just shanghai this rather nice mini barebones box. We won't need the original mobo though we might be able to use the PSU.
11. Compact and decidely bijou

step 11

This box has space for two PCI cards, so even a double-width graphics card should easily fit inside the chassis and the PCI-e adaptor sits nicely, where the mobo used to be.
12. Get the power that you really need

step 12

It's important to make sure the power supply unit's 12v rail will meet the power supply needs of the card. Check the Wikipedia entry to look up the TDP of your chipset if you're unsure.
13. Get a cable, that is Type C

step 13

We're going to route the connecting cable out of the side of the case. To make life easier it'd be best to pick up a longer mini HDMI (Type-C) cable, which is actually what the cable is.
14. Connect up the power button

step 14

The ATX PSU is activated by connecting pins 14 and 15 (20-pin) or 16 and 17 (24-pin) together. It's the green wire and any black wire, so you could connect up the case's power switch instead.
15. And this is one I made earlier…

step 15

And here she is, our neatly finished solution for getting desktop graphics on your weedy laptop. The mini-case, as it turns out, makes quite a handy monitor stand. Or you can just hide it away.

MacBook Pro goes slim with quad-core this Spring


This summer we’re very likely going to see MacBook Air slimness on Apple’s line of heavier-duty MacBook Pro units, complete with Intel’s Ivy Bridge quad-core processors in-tact. This information is gleaned from no less than Intel themselves, with news coming through that April 29th will be the date that they’re ready to show the world what they’re made of in both the mobile and desktop world. CPU World lets us know that two separate and trustworthy sources have now confirmed that this date late in April will be the delivery time for for desktop portion of this equation, with quad-core models Core i7 and Core i7 Extreme families in the pipeline.
This news comes with the following part names attached inside the Core i7 family: desktop Core i7, Core i5-3570K, i5-3570T, i5-3550, i5-3550S, i5-3450 and i5-3450S. These systems on chips will be available in late April or early May and will find their way into devices such as MacBook Pros thereafter. New iMac machines have also been tipped for this timeframe, but no additional details are known on specifications of any kind.
We can expect that the MacBook Pro refresh will be delivered (if all goes according to the standard non-official plan of things), this spring right around the same time as the processors themselves are prepared for business with the rest of the computing world. This refresh will be the first in which Apple gets rid of the optical disk drive altogether, favoring instead digital data delivered via USB drive and their own Thunderbolt port.
Get pumped up about the thinness, because these units are more than likely going to be essentially Ivy Bridge-toting MacBook Airs with much better graphics, hard drives, and processing power. Can’t wait!

Lenovo launches IdeaPad U300s Ultrabook in India


After the Acer S3, Lenovo steps in the Ultrabook segment with the launch of the U300s. Available from all major retail outlets, the IdeaPad U300s is priced at Rs.67,900, plus taxes. The U300s is built from a single piece of aluminium that form the chassis, similar to the MacBook Air. Due to this, it has a thickness of just 14.9mm and weighs less than 1.3 kg. It also packs in some technologies like ‘Breathable Keyboard’, which uses Intel’s Advanced Cooling Technology, which allows air to flow in through the keyboard and out the sides and the rear hinge.

This design removes the need for vents on the underside of the notebook, making it ideal for long periods of use. The Lenovo Long Life Battery provides the U 300s up to 8 hours of productive use or 30 days on standby. With Lenovo RapidCharge, the battery can be charged to 50 percent capacity in just 30 minutes. 

The 13.3-inch HD ready screen is LED backlit and the notebook is powered by Intel’s 2nd Generation Core i5 processor, 4GB of RAM and 128GB SSD. Along with that, we also have Bluetooth 3.0, Wi-Fi ‘n’, USB 3.0 and 2.0, HDMI, SRS Sound enhancement, Intel’s WiDi technology and finally, a 1.3MP webcam. Acer’s similarly speced Ultrabook is actually slightly cheaper, so it’s interesting to see what special Lenovo’s offering will bring to the table.
