Porsche piwis 2 with Panasonic Toughbook 31

Many customer ask about the difference of porsche piwis 2 with cf30 and cf31? What's the main difference of the two device?

As we can see is the part of porsche piwis2 is the same, so the only difference of them is the laptop difference.

Porsche piwis2 with cf30 laptop is just 1999usd

porsche piwis 2 with cf31 laptop is 4350usd, what makes the big difference of them?

Today let's give you the answer about it.

cf30 laptop is intel core 2 duo cpu, 7500. 3G RAM, 120G or 250G HDD. While the cf31 is big difference

 Much more performance, great battery life, a super-bight display and many new features mark the 6th generation of Panasonic's milestone rugged notebook computer platform

Update September 18, 2012: Following upgrades to the Panasonic Toughbook 19 fully rugged convertible tablet PC, the Toughbook 31 rugged notebook also received substantial tech upgrades. First and foremost, there are now Intel 3rd generation processors (i5-3360M, i5-3320M, and i3-3110M), boosting graphics performance (by a lot), overall performance, and boost battery life. i5 models now have 500GB 7,200 rpm drives, 802.11a/b/g/n is now standard, and there is a USB 3.0 port for much faster throughput. Prices for the updates Toughbook 31 start at an estimated street price of US$3,499

Panasonic's flagship Toughbook hardly needs an introduction. Few computers have the history and pedigree of the rugged Toughbooks that hold a special place as perhaps the most popular rugged notebook computers ever made. In mid-2010, Panasonic announced the Toughbook 31, a fully rugged notebook computer for tough jobs in the field, in vehicles, and in any situation where a standard notebook would quickly fail. The Toughbook 31 replaces the Toughbook 30 with a variety of technology updates and enhancements that brings the platform technologically up-to-date without obsoleting existing customers' investment in older Toughbook docks and peripherals. In fact, this 6th generation of Panasonic's original rugged notebook platform now has eleven years' worth of vehicle dock compatibility. That's remarkable as it means that Toughbook 27, 28, 29, 30, and now 31 computers can all co-exist and use the same support infrastructure.

What's new in the Toughbook 31?

What has changed with the latest Toughbook 31 model? Most noticeably that Panasonic switched from Intel Core 2 Duo power to the latest Intel Core i3 and i5 processors. The three processors available in the new Toughbook 31, together with the new Mobile Intel QM57 Express chipset, are all part of Intel's "Calpella" platform. porsche piwis2 with cf31 laptop These 32nm lithography chips include the memory controller and fairly powerful integrated graphics with high definition video hardware acceleration right into the processor, and are essentially the successors of the Core 2 Duo CPUs.

It gets a bit involved here as Intel offers a large variety of new Core i3, Core i5, and Core i7 processors and there are ultra low voltage, low voltage and standard voltage versions, with some designed for mobile use and some for the desktop. Of all these, Panasonic chose a "low end" Core i3 (the 2.26GHz Core i3-350M) and two higher end i5 chips (the 2.40GHz i5-520M and the slightly faster 2.53GHz i5-540M). Note that the latter two also have a "Turbo Boost" mode that automatically allows processor cores to run faster than the base clock frequency if the CPU is operating below power, current, and temperature specification limits. So the two i5 chips max out at 2.93 and 3.07GHz.

While the new processors are the big story, the Toughbook 31 benefits from new and ever better technologies in other ways as well: the capacities of the available shock-mounted and removable SATA hard disks are up to 160 and 250GB. That's perhaps a bit modest still as larger disks are now available. No argument, though, about the optional solid state disk -- who'd have thought a few short years ago that we'd have 256GB SSDs!? With the new processors, memory was switched to speedy 1066MHz DDR3, with a maximum of 8GB. An additional USB 2.0 port brings the onboard total up to 4, and there's now an HDMI port in addition to VGA.

Below you can see the older Panasonic Toughbooks of this series, starting with the CF-27 back in 1999.

Design, look, and feel

Having followed the evolution of the Panasonic Toughbooks ever since I assumed the position of Editor-in-Chief of Pen Computing Magazine back in 1993, what impresses most is Panasonic's unerring, single-minded dedication to the ongoing improvement of the platform. It's a veritable quest for perfection, with Panasonic engineers agonizing over every tiny detail. There's no badge engineering here, no switching of suppliers (Panasonic makes virtually everything that goes into a Toughbook itself), no midstream course corrections, and no uncertainty about mergers or acquisitions or changes in policy. All of that combines to generate exemplary quality, exemplary longevity, and, perhaps most important of all, peace of mind for Toughbook customers.

There's really no describing just how solid a Toughbook feels, and how Panasonic somehow improved on the industrial design directive of "form follows function" by making form beautiful as well as functional. I sat in meetings with Panasonic engineers where they explained the "pencil hardness" of finishes and coatings, and how hardness relates to touch, abrasion and how they were shooting to improve hardness from 3H to 6H. I recall discussions of ph levels, and how acid from sweat may affect or break down plastics. It all matters, and the end result is a machine like the Toughbook 31. The powercoat finish of its LCD case is simply unbelievable, as is its design, and the design of the entire computer, down to the most minute detail.

But lets take a look at the matte-silver and black Toughbook, which measures 12 x 11.5 x 2.9 inches and weighs just under nine pounds. It's a big, substantial machine, though in an era of 17 and even 19-inch laptops, the 31 looks and feels downright svelte. Below you can see the top and all four sides of the machine:

porsche piwis2 with cf31 laptop

Ports and connectivity are spread around the machine including the front that features, besides the springloaded on/off/sleep lever, a fingerprint reader and the Toughbook-trademark magnesium carry handle that can now accommodate the supplied 5-inch-long plastic stylus. Note that all ports sit behind protective doors of various designs and technologies. Noteworthy here is that the Toughbook 31 now has positive "click-lock" port covers that offer more reliable sealing and protection. This design, where you first push a cover closed, then move it up until it locks with a noticeable snapping sound, was first seen on the Toughbook U1, and it's certainly an improvement over the older-style port covers.

The picture below shows the backside of the computer, with all of its ports exposed. On the right is a separately sealed RS-232 DB9 port for legacy support. The rest of the ports are all beneath a single hinged cover that includes a slider to provide access to the expansion bus and external antenna connectors. The door is secured with a spring-loaded latch that's a bit of a fingernail breaker. Also under the door are two USB 2.0 ports, an external display port and separate headphone and microphone jacks. To the left of the door is a Kensington standard slot so you can secure the Toughbook with a cable.

The two pictures below show the left (top) and right (bottom) side of the unit.

On the left side, two third are taken up by a large hinged door behind which you find the optical drive (in our unit a DVD writer), a PC Card Type II slot, an ExpressCard/54 slot, an SDHC card slot, a Smart Card slot, and a small wireless on/off switch that's well-enough hidden to potentially cause some anxiety when it's off and there isn't any wireless connection. Next to it all is the lockable battery compartment and on top of that a ventilation hole for the Toughbook's fan. Yes, there is now a fan to deal with the extra heat of the powerful i5 processor, but it's small and innocuous and hardly ever seems to come on.

On the right side are no fewer than five separate separate doors. They protect an HDMI port, a SIM card slot, an RJ45 LAN port, an optional RJ11 modem port (people are still using modems?), two more USB 2.0 ports, and a power jack. To the left is the hard disk compartment whose door has both a latch and a security lock.

Worth mentioning is the way Panasonic designed the LCD case lock. This is important in rugged machines designed for outdoor use as the lock must be both strong and reliable enough to keep the computer from opening by accident, but also easy enough to operate so that it can be done with gloves on. To accomplish that, Panasonic designed a see-saw lock that solidly locks the LCD case against the main body of he computer with just a slight push, and also easily opens when pushed on the opposite end. The LCD case also has two small bolt-like bumps that fit into sleeved indents on the bottom part and preclude twisting of the LCD case when it's closed.

Keyboard and touch pad

porsche piwis2 with cf31 laptopThe Toughbook's keyboard is full-scale and has 87 keys. The fairly flat keys are black with white letters, numbers and symbols. The keys are backlit and go, via keyboard control, from off to full-bright in five steps. There is no separate keypad, but keypad functionality is available with the usual number keys assigned to the numbers 7, 8, 9, and the letters uio, jkl, and m. Overall, all those labels and icons make the keyboard look a little busy, but regular users will get the hang of it in no time.

Below the keyboard is the unit's touch pad. It is a small, recessed affair with the two mouse buttons in front of it. I am no big fan of this touch pad as it's so small that my fingers constantly bumped into its perimenter, and it also required a rather firm touch to get the cursor to move. There may be reasons for this design, but I'd prefer a larger and more cooperative touch pad. Beneath the touch pad assembly are seven indicator lights, each with an icon. I only recognized two without looking things up, so they are not terribly obvious. We criticized the Toughbook 27's equally small and unresponsive touchpad way back in 1999, and again in the reviews of the CF-29 and CF-30, and it's not clear why this is still an issue.

Panasonic must have had its reasons for this latest keyboard design, too, but there will be those who prefer the keyboards of older Toughbooks with their more legible large letters on gray and black keys and more commercial notebook design.


All notebook computers represent a compromise between performance, size, weight, battery life and cost. If you want a powerful processor with a lot of speed, that means more heat and less battery life. You can put in a bigger battery, but then the computer gets large and heavy. On the other hand, if you want a small, quiet computer without a fan, it will probably have much less performance. So, it's more speed, more heat, less battery life. Or more battery life, less performance, less heat. If you want more performance AND more battery life, it's more weight, AND more heat. So you can see that it's a compromise, and that's what Panasonic was facing when picking processors for this new version of the full-size Toughbook. In the past, Toughbooks usually had relatively low power processors that emphasized battery life.

porsche piwis2 with cf31 laptopFor the new Toughbook 31, however, Panasonic took a different approach and chose three rather high-powered chips in the 2.26GHz Core i3-350M, the 2.4GHz Core i5-520M, and the 2.53GHz Core i5-540M (present in our review machine). All three have a thermal design power of 35 watts, twice as much as the Core 2 Duo processor used in the Toughbook 30. These are what Intel calls "standard voltage" processors, as opposed to the low voltage and ultra-low voltage versions. Yet, for Core i5-powered Toughbook 31s, Panasonic claims even longer battery life than the already amazing ten hours specified for the predecessor Toughbook 30 with its lesser processor. Is that possible?

It actually is. That's because Intel's new Core processors, while offering very impressive performance, are extraordinarily frugal thanks to advanced power savings techniques. So Panasonic is quoting 11 hours on a charge for Core i5 machines if using the integrated Intel graphics, and about 5 hours for an i5 machine running the discrete, switchable ATI Radeon graphics available with i5-540M models. Note that the fairly power-hungry discrete ATI graphics must be enabled in a BIOS setting.

To see what kind of performance the Core i5-540M-powered Toughbook 31 can deliver with and without discrete graphics engaged, we ran our standard benchmark suite, Passmark Software's PerformanceTest 6.1, that runs about 30 tests covering CPU, 2D graphics, 3D graphics, memory, and disk and then computes scores for each category and an overall PassMark score. We also ran our second benchmark suite, CrystalMark, for confirmation and additional information. For comparison, we included the benchmarks of two direct competitors with late model Core 2 Duo processors, the Getac B300 currently still with an older version of the Core 2 Duo, and the Motion J3500 tablet computer with an ultra-low voltage Core i7 processor.
