[HOTHOT Review] Panasonic "LET'SNOTE R9" -Panasonic -PC Watch with the world's smallest body with Core i7 -PC Watch

The smallest size of the "Let'sNote" series spring model announced by Panasonic is 10."Let'sNote R9" equipped with a 4 -inch liquid crystal.Let'sNote R9 is almost the same as the previous model Let'sNote R8, but the CPU has the latest Core i7 and has greatly improved its performance.Let'sNote R9 is now the smallest of the world as a core i7 laptop, and is a very attractive product for those who value portability.This time, I got the opportunity to try Let'sNote R9, so I would like to review it immediately.

In addition, since the trial machine was used this time, the details and performance may be different from the product version.

In the Let'sNote Spring Model announced this time, the CPU has been changed from Core 2 series to Core I series, but products other than Let'sNote R9 are usually equipped with a normal voltage Core i5-520m.On the other hand, Let'sNote R9 is the only ultra-low voltage version of Core i7-620um.

The series name is higher, and the latter is larger, so some people think that Let'sNote R9 is more performance, but Core i5-520m clock 2 clocks 2..While it is 40GHz, the clock of Core i7-620UM is less than half of it..It is 06GHz, and the number of cores is two (Hyper-Threading technology is compatible, so the thread that can be executed at the same time does not change, so the CPU performance is higher for Core i5-520m.This is a branding problem with Intel's mobile Core series, which is difficult to judge by the series name.However, the clock improvement rate by Turbo Boost technology with the automatic overclocking function is larger in Core i7-620UM, up to 2..The clock is improved to 13GHz (twice as rated), whereas Core i5-520m is up to 2.93GHz (approximately 1 rated.The clock is improved only to 22 times).The L3 cache capacity is 4MB for Core i7-620UM, while Core i5-520m is 3MB.

The previous model Let'sNote R8 is Core 2 Duo Su9600 (1) as a CPU.It was equipped with 60GHz), but the TDP of Core 2 Duo Su9600 is 10W, while the Core i7-620UM TDP is 18W and 1..Due to the increase in 8 times (although Core i7-620UM has a function that the North Bridge has been in charge of, such as GPU and memory controller), it was difficult to put it in the same body.In Let'sNote R9, the CPU cooling fan is larger than the R8 and moved it to the substrate side (in the past, a fan was installed on the base unit side), which achieved about three times the air volume.is.

Equipped with VPRO compatible Intel QM57 Express as a chipset.The memory is implemented as standard and has one DDR3 So-Dimm slot, so it can be added up to 4GB.The HDD capacity is 250GB.In the Milez Club on the direct sales site, the CPU is a higher rank Core i7-640um (1).It is 20GHz), with 500GB HDD or 128GB SSD, and you can purchase high -spec models and premium editions with additional Bluetooth.The body size is 229 x 187 x 29 as the previous model.4-42.5mm (width x depth x height), weight is about 0 as the previous model.93kg.

Although the OS of the over -the -counter model is Windows 7 Professional 32bit version, it is possible to select the 32 -bit and 64 -bit version by using the "Hard Discritable Function".

As an liquid crystal display, 10.Equipped with a 4 -inch liquid crystal.It is a 4: 3 aspect liquid crystal, which is now a minority, and has a resolution of 1,024 x 768 dots.Like the other Let'sNote series, it uses a non -glare type LCD, so it is inferior to glossy type (glare) liquid crystal in terms of contrast and vividness of coloring, but has little reflection of external light and long hours.Even if you use it, you have less eye fatigue.It can be said that it is a suitable specification for work.

The keyboard is a bit cramped because Let'sNote R9 has the smallest body in the Let'sNote series.The horizontal key pitch of the main key is 17mm, but the vertical key pitch is 14.It is only 3mm, and the keytop is a horizontally long rectangle.In addition, some key pitches on the right, such as "mu" and "ke", are narrowed, and "half -width/full -width" is located at the top.If you get used to it, you can do touch typing, but some people feel uncomfortable until they get used to it.As a pointing device, the Let'sNote series is equipped with a familiar circular wheel pad.The wheel pad is characterized by continuous scrolling operation, and has good operability.

The interface is basically the same as the previous model Let'sNote R8.USB 2.It has 0 port x 2, mini D-sub15 pin, Gigabit Ethernet, etc.Since the placement of the port is the same, those who have used the R series can move as they are.USB 2 on the left side.I would be more happy if there was a 0 port, but it would be difficult with this unit with a small body size.It has a PC card slot and an SD memory card slot as a card slot.The SD memory card slot is prepared in front of the main unit.

As a wireless function, IEEE 802.Equipped with 11a/b/g/n compatible wireless LAN.Unfortunately, unlike the S9/N9/F9, it is a pity that it is not equipped with WiMAX, but this seems to be because the body size is limited to the implementation of the antenna.The store model is not Bluetooth, but as mentioned above, the Milets Club limited model also supports Bluetooth.On the right side of the front is a wireless switch, which is convenient because you can quickly switch the wireless function's validity/disabled.

In Let'sNote R9, the lithium -ion battery used in the battery pack has been changed to the latest 3,100mAh cell from the 2,900mAh cell used in the conventional Let'sNote R9, with a battery capacity of 7 %.The number is increasing.The CPU has been changed from Core 2 Duo SU9600 to Core i7-620UM, so the nominal battery drive time is about 8 hours to about 7..It is about 30 minutes shorter to 5 hours, but it is within the range that can be satisfied with the improvement of performance.The AC adapter is as compact as before, and the weight including AC code is about 215g, so the portability is excellent.

I measured the benchmark for reference.The benchmark programs used are "PCMark05", "3DMark03", "FINAL FANTASY XI Official Benchmark 3", "Stream Output Test for terrestrial digital broadcasting", and "CrystalDiskMark", Panasonic "LET'SNOTE F9" for comparative comparisons.The values of ThinkPad T400S Windows 7 Model, Epson Direct "Endeavor NA501E", and NEC "Lavie M" are also posted.

The comprehensive score of PCMark05 is 3872, about 14 % higher than the Endeavor NA501E equipped with Core 2 Duo SU9400.There was no bench result of the previous model Let'sNote R8, so it is not possible to compare directly, but if the CPU of Endeavor Na501E is higher, it will be almost the same as the Let'sNote R8 specifications.The CPU Score is 4520 and is about 24 % higher than the Endeavor NA501E equipped with Core 2 Duo SU9400.Even if the clock difference is taken into account, it can be said that Let'sNote R9 has better performance than Let'sNote R8.Indeed, although it is not as good as the score of the normal voltage version of Core 2 Duo, it can be said that it has a top -class performance in a mobile notebook PC of less than 1 kg.

In addition, the benchmark result of the battery drive time by BBENCH (wireless LAN is always ON, backlight brightness) is 6 hours and 2 minutes, which is also excellent.

LET'SNOTE R9 is about two times smaller than the A4 size and weighs about 0..It is attractive that 93kg's high portability and performance that can move Windows 7 comfortably.In terms of size and weight, ATOM Z -equipped machines have smaller and lighter products, but with ATOM Z -equipped machines, they often feel dissatisfied with their performance.It is a product I would like to recommend for those who want a light and small machine but do not want to sacrifice performance.

The estimated price of LET'SNOTE R9 is around 180,000 yen, and is the same as the previous model Let'sNote R8.Although the price is higher than the Atom Z -equipped machine and the CULV notebook PC, the LET'SNOTE series clears the 100kgf pressurized vibration test and the 76cm fall test, and also realizes the full keyboard drip -proof.There is a merit of ruggedness that is not found in ultra -small mobile PCs.For those who carry mobile PCs as a work tool, they will be the most strong ally.
