Among the mainstream notebooks in the 5k price range, the most popular ones have always been Hewlett Packard Battle 66, Xiaomi Notebook Air/Pro and Lenovo Xiaoxinchao 7000. The configuration and pricing are very similar, but the design and tuning focus of the manufacturer are very different.
The special one is HP Battle 66, which is a business product designed by HP for SMEs in the Chinese market in September 2017. At the end of 2017, HP launched the War66 Pro high color gamut version, which updated the screen and hard disk based on the original configuration of War66, and passed the AutoCAD certification. Later, on March 2 this year, HP released the unlocking long-life BIOS, which joined the high-performance mode. Now let's see how the 66 Pro high gamut version performs after improving the screen, performance and business features.

appearance
With the 66 Pro high color gamut full silver fuselage, the external A and D surfaces are frosted surfaces with glitter, while the C surface that users contact most is a metal wire drawing pattern. This is a familiar low-key business notebook design. Although it is called an ancestral abrasive by netizens, it is better than fingerprint and oil stain prevention. It is not easy to look old without such care. The A-side lift cover has a bulge for easy opening and closing, which can be opened by one hand without dragging the body. The screen shaft is tight, and the limit angle is 145 degrees.
The whole weight of the fuselage is 1.64kg, and the thickness is 19.95mm. It is certainly not as good as the super extreme version, but it is better than the "cow turtle" impression of the traditional business version.
The top of the 66 Pro high color gamut keyboard is HP's familiar speaker mesh, and the bottom right corner is a sliding fingerprint. This nominal "professional business keyboard" has a splash proof design and a drain hole through the body. 1.5mm key stroke, 60g keystroke force, slightly biased. When you type the keyboard, the sound and touch of the keyboard area give you a very solid feeling.
The right side of the keyboard has more head and tail jump and page up and down columns, and the position of the direction keys is much looser than that of conventional machines. Personally, I prefer this keyboard. The biggest regret is that there is no backlight.
The number of interfaces is the most obvious feature of the 66 Pro high color gamut version, which is a practical business book. It does not require additional card readers and adapters. The 66 Pro high color gamut version has anti-theft keyhole, heat dissipation grille USB 3.0、 Headset, SD card reader, Type-C interface on the right, USB 3.0 supporting power off charging HDMI、 VGA and RJ45 network cable interfaces and power ports, which are rare but always used occasionally.
In the heat dissipation grille, there is a layer of heat dissipation net in the middle upper part and left side of plane D. The power adapter is manufactured by QUOTE, with a total power of 65W, which is shorter and smaller than the common one.
Screen: This is the baseline of the business screen
The name of the 66 Pro high gamut version indicates that the focus of this minor revision is the screen, and the core is "fog surface IPS, 300 nit brightness, 100% sRGB gamut". There is no need to say more about the first foggy IPS. Although mobile phone screens have long been popular with IPS, there are still some laptops with more than 5K using the TN screen of Kendal, and the viewing angle is terrible. The visual angle of the 66 Pro high gamut version is normal, and it will not affect the appearance within 160 degrees.
The gamut size of the War66 Pro high gamut version exceeds 100% sRGB, but because of the position shift of the green point, it actually covers 94% of the sRGB gamut (the closer to 100%, the better). The saturation between blue and green is higher than the sRGB gamut, while the saturation between red and green is slightly lower.
After solving the problem of brightness and visual angle, the next important standard is the color gamut size. The direct impact of low color gamut is that the image is dim, and the deviation from the real image is large. But now the color gamut of mainstream notebooks is between 50% - 80% sRGB.
In terms of color accuracy, the average deltaE of the 66 Pro high gamut version is 5.2, and the maximum deltaE is 11.1 (the smaller the value, the better). Notebooks that perform better than the price range are close to the average color accuracy of mobile phone screens. If you can compare colors by yourself, or even just correct white dots, you can make this screen work better.
On the whole, this is a laptop screen with good quality. It is not PWM dimming, and there is no flash screen. The brightness, visual angle, anti reflective ability, color gamut coverage and other indicators exceed the normal values of the notebook.
Performance misfire: Generation 8 Core and full blood MX150
HP's official slogan for the 66 Pro high color gamut version is "Double Blood", referring to the 8th generation i5 and i7, and the 25W version of the MX150 graphics card. What we got was the second high configuration of the 8th generation i7 with a 500G mechanical hard disk.
Basic parameters
I7-8550U and MX150
The CPU part of the mobile version of the 8th generation Core is the "largest toothpaste" that Intel has squeezed out on the mobile end for so many years. The number of i5 and i7 cores has doubled directly, becoming 4 cores and 8 threads. I5-8250U has a default frequency of 1.6G, and the maximum Remax frequency is 3.4G; The i7-8550U has a default frequency of 1.8G, and the maximum Remax frequency reaches 4G. This increase is not appropriate to describe as a performance boom, which is simply a performance misfire. The mobile version of the eight generation i5 can compete with the seven generation i7. The TDP of both CPUs can fluctuate between 10-25W. How long can they stay strong at the highest frequency? It depends on the manufacturer's cooling configuration, TDP and temperature wall settings.
At first, people thought that the MX150 in the GPU part was just an entry product to replace the previous generation 940MX. As a result, the MX150 nearly doubled its performance. However, it should be noted that MX150 has two versions: low-power version and full blood version, the former is 8W TDP， The latter is 25W, and the performance gap is between 20% and 30%. It can be understood that it is not the same thing anymore.
The 25W full blood MX150 equipped with the 66 Pro high gamut version, The GPU code is 1D10 (1D12 for the low-voltage version). It uses the GP108 core, 384 stream processors, the default frequency is 1469MHz, and the typical boost frequency is 1532MHz (some products can reach more than 1.7G in daily use), which is slightly higher than the same source desktop version of the GT1030. 2GB GDDR5 video memory, 64bit video memory bit width, 48.1GB/s bandwidth. The GPU frequency of the low-power version MX150 is only 937MHz, and the typical boost is only 1038MHz. Although the peak value of the latter can also reach more than 1.6G, the TDP and video memory frequency are lower, and the performance output gap between the low-power version and the full blood version is obvious.
Before testing the performance of the 66 Pro high color gamut version, it should be noted that HP released the unlocking long-life version BIOS on March 2. The biggest change in this BIOS update is the addition of the "high performance" mode option, The CPU performance tuning will be more "full blooded", and the CPU full load power consumption can still maintain 12W during double baking, which has been very touching for this thickness of business book.
In the Fire Strike Extreme test with very high load in 3DMARK, under the high-performance mode of the 66 Pro high gamut version, the total score is 1496, the graphics card score is 1496, the physical score is 5987, and the platform score is 651. The performance is better than expected.
Fire Strike Test
Sky Diver Test
Cloud Gate Test
In the 3DMARK test, in four different scenarios, except for the Fire Strike Extreme test where the test load is much higher than that of this level of graphics card (the bottleneck appears in the graphics card, and the CPU growth cannot be shown), in the other three tests where the load is relatively low, the high-performance mode has immediately improved, and the fan noise is completely acceptable.
The creation test of PCMARK is aimed at advanced users. In addition to the content of home test, it also includes batch processing of pictures, video editing, and video pushing
, video group chat and other tests to test the overall performance of the whole machine. The score of the 66 Pro high gamut version was 3499, and the performance was good.
Frequency and temperature monitoring in Fire Strike Extreme test
After all, the i7-8550U is a 4-core 8-thread CPU. Under the control of this TDP, it is impossible not to reduce the frequency. However, after upgrading the BIOS for the 66 Pro high gamut version, even though the CPU frequency is reduced, it still remains above 3.4G, which is completely OK.
To sum up, the performance output of the full blooded MX150 is between 950M and 960M, which has reached the level of the previous generation of entry-level game books. Although the GPU in the toaster will still reduce the frequency due to the heat dissipation limitation, most games have not seen the frequency reduction. The high gamut version of the game making 66 Pro can even maintain 30 frames of chicken eating under 1080P full low special effects, refreshing the author's impression of the performance of notebook games at this level.
The Turbo Drive PCI-E SSD of the 66 Pro high color gamut version is really the Samsung PM961 that everyone is familiar with. The model MZVLW256HEHP-000H1256G is as strong as ever, and the performance of the hard disk is super at this level.
The temperature control of the 66 Pro high gamut version under high intensity use is satisfactory. Under high performance, 3DMARK runs for 20 minutes continuously. The highest temperature on the front of the 66 Pro high gamut version appears in the middle of the keyboard, about 46 degrees. The highest temperature of the whole machine is 47.6 degrees at the left air outlet.
Normal mode and high performance mode
In the normal mode, the noise is about 46.6 decibels, while in the high-performance mode, the wind noise will increase to 51.5 decibels. The former is hard to detect in office scenarios, but the latter can be easily heard. However, considering the improvement of performance output, the author thinks it is acceptable.
Business surrounding
Although the official propaganda makes Zhan 66 Pro high color gamut version look like a game book, its own positioning is a business book. There is another set of specifications for design durability, stability and professional certification.
The 66 Pro high color gamut version retains the ancient compatible interfaces of VGA and RJ45. Although everyone will spray them, let alone business life, they will be occasionally used in normal office classes.
Zhan 66 Pro high color gamut version is the first mainstream notebook at this price that has passed the AutoCAD certification, and has passed 240 industrial software and hardware compatibility and stability tests. This is the certification for workstation products. The last non workstation product that passed this certification was Microsoft Surface Book.
Intel's dual band network card AC8265, with dual sending and dual receiving, has a maximum speed of 867Mbps, supports MU-MIMO and Intel vPro management platform, and pre installed HP Velocity network acceleration software, which is used for network transmission optimization and can be adjusted adaptively according to network congestion. The latter won the American Technology Software Award in 2014, It is one of the few pre installed software that is really useful and has won prizes.
War66 Pro's high color gamut version also passed the humidity, high altitude and low humidity, drop and impact, dust, vibration and other nine military standard tests of the U.S. Department of Defense MIL-STD-810G, which is obviously the business book setting for benchmarking entry-level ThinkPad. In terms of warranty, it is also very "commercial". Six months of 7 * 24 online engineer customer service and one year of on-site maintenance are expected to hit the pain points of many lazy users and enterprise purchasers.
summary
The 66 Pro high gamut version has upgraded the screen SSD、 Add certification. Although it is a business book, the radical 8 generation of core, full blooded MX150, PM961 solid state disk, and official publicity of temperature control and tuning are somewhat like an introductory game book. However, the richness of interfaces, military certification, AutoCAD certification and door-to-door maintenance are all things that traditional business would have. High cost performance pricing and basic performance make its target users cover students, white-collar workers, and even entry-level design users.
Make the product cost-effective, but still maintain the bucket performance, such as the joke "ordinary family Ma Huateng, regretting Ali Jack Ma, penniless Wang Jianlin, not knowing his wife, Mei Liu Qiangdong, and making money by the way Ding Sanshi, ordinary and ordinary," which is a practical player suitable for living, under the understatement of balanced performance, It is the blood and tears of designers and engineers.
