MagyarMSI GP66 Leopard 10UG Laptop Review: A Complete Series Overhaul
Unveiled earlier this year alongside the mobile Nvidia Ampere series, the GP66 introduces a brand new design over the older GP65. Almost everything has changed from the keyboard to the cooling solution to represent the start of a new generation for the GP family. For those unfamiliar, the GP series is home to MSI's mid-range gaming laptops above the cheaper GL and GF series and below the pricier GE and GT series.
SKUs range from an Intel 10th gen Core-i7 10870H CPU with GeForce RTX 3060 graphics up to the Core i7-10875H with RTX 3080. Our review configuration is a middle configuration with the i7-10870H and RTX 3070 for around $2500 USD depending on the RAM and storage.
Competing models include other upper mid-range 15.6-inch gaming laptops like the Gigabyte Aorus 15P, Asus ROG Zephyrus G15, or Lenovo Legion 7.

Case
The biggest physical change from the GP65 to the GP66 is the larger rear in order to accommodate a more powerful cooling solution. The overall visual design can otherwise be best described as a toned down GE66 with their similar smooth metal outer lids but a darker black color scheme. The RGB light bar along the front edge of the GE66 is not present on the GP66 while the per-key RGB keyboard lighting remains.
Build quality is excellent especially for the base. The keyboard deck exhibits just minimal flexing and creaking when bending or twisting its front corners. The lid, however, could have been stiffer as the hinges tend to teeter when adjusting angles. The outer lid also flexes more readily than on the Asus ROG Strix G15 when applying pressure down its center.
The new design is noticeably longer than the older GP65 in length because of the new "jet engine" rear. Otherwise, weight remains nearly the same gen-to-gen at 2.3 kg and the system is actually thinner this time around by about 4 mm. The competing Alienware m15 R4 is even larger while the Asus Zephyrus G15 GA503Q is both lighter and smaller.
Connectivity
Port options and positioning have changed significantly from the GP65. For one, the ports are now more evenly distributed along the left, right, and rear edges whereas they were all clumped together on the GP65. Secondly, both the 3.5 mm microphone and mini-DisplayPort ports are now gone in favor of DisplayPort-over-USB-C. HDMI has been upgraded from 1.4 to 2.0 for 4K60 support and there is an extra USB-A port for three in total.
Keep in mind that Thunderbolt and USB-C Power Delivery are not supported. Thus, users cannot recharge the GP66 with USB-C adapters unlike on the Razer Blade 15 or Alienware m15.
Communication
Webcam
Maintenance
Servicing is more difficult than on the GP65 because the bottom panel on the GP66 is much tighter around the edges and corners. A sharp edge and a careful hand are necessary to safely remove the panel. Once inside, users will have direct access to 2x M.2 2280 slots, 2x SODIMM, battery, and the WLAN module.
Accessories and Warranty
There are no extras in the box other than the AC adapter and paperwork. The velvet cleaning cloth that is included with GS and GT series laptops is not included here.
The standard one-year limited manufacturer warranty applies.
Input Devices
Keyboard
The keyboard is identical to the keyboard on the GE66 and a huge departure from the GP65. The NumPad, for example, is now gone and travel feels shorter with crisper feedback in return. Clatter is also slightly louder and higher-pitched than before especially in regard to the Space and Enter keys.
Per-key RGB lighting returns. The lighting could be more uniform, however, as the secondary key symbols (i.e., !, @, #, etc.) do not glow as brightly as the main symbols (1, 2, 3, etc.).
Touchpad
The plastic clickpad is relatively small (10.5 x 6.5 cm) with a smooth glide at medium-fast speeds and just a bit of sticking at slower speeds for more accurate clicks. Its integrated click keys are spongy and they require more force than usual to register which can become tiring if you don't have an external mouse. Though the new clickpad is serviceable, we do miss the dedicated mouse buttons and firmer clickpad on the older GP65.
Display
Our GP66 10UG configuration uses the same 240 Hz Sharp LQ156M1JW03 panel as found on the GE66 10SFS, GS65 Stealth 9SG, Razer Blade 15, and Aorus 15P XC. Colors, contrast, and response times are therefore similar between all these laptops which is a good thing since many of these models are high-end gaming systems.
A key difference on the GP66 display when compared to the aforementioned laptops is that it is noticeably dimmer. Maximum brightness tops out at about 210 nits whereas most other gaming laptops are 300 nits or brighter.

* ... smaller is better
Color space covers all of sRGB to be comparable to most high-end gaming laptops. We're glad that MSI isn't using one of those cheap Panda panels which typically have much poorer colors.
X-Rite colorimeter measurements show an uncalibrated display out of the box which is to be expected since the GP66 is not a flagship Pantone-calibrated gaming laptop. Color temperature is too cool and color accuracy suffers as a result. Colors improve significantly once properly calibrated with final grayscale and color deltaE values of just 1.5 and 1.15, respectively. We recommend applying our ICM profile above to get the most out of the display if you don't have access to a colorimeter.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 23580 Hz | ≤ 34 % brightness setting |  |
The display backlight flickers at 23580 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 34 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 23580 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17933 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
Outdoor visibility is poor as the display is not that bright. Glare is noticeable under most conditions and even if it could be reduced, onscreen content will appear washed out anyway.
Performance
MSI is only offering 10th gen Comet Lake-H Core i7-10870H and Core i7-10875H options at the moment with nothing else. However, we would've been fine with just one of those options only as any differences between the i7-10870H and i7-10875H are incredibly minor. Users will have to look at the cheaper Bravo or Alpha series for AMD options.
Graphics range from the GeForce RTX 3060 to 3080 at 130 W TGP each. Both automatic and manual graphics switching are available via the Dragon Center software. We recommend owners become familiar with Dragon Center as key features are toggled here.
We had set our unit to Extreme Performance mode with the Nvidia GPU active prior to running any performance benchmarks below.
Processor
CPU performance is excellent with decent Turbo Boost sustainability as shown by our CineBench R15 xT loop results below. Performance is even as fast as the more expensive Core i9-10980HK in the Alienware m15 R4. Differences between the Core i7-10875H and Core i7-10870H are within just a couple of percentage points.

Emissions
System Noise
The fans will idle when the laptop is idling on desktop with no other active programs. However, even a slight increase in CPU utilization will kickstart the CPU fan and so the laptop will not be truly silent under most real-world scenarios. We're able to record a noise of 32.8 dB(A) when web browsing or video streaming against a silent background of 24.7 dB(A). It's enough to be noticeable but not particularly bothersome.
Fan noise when gaming will hover around 48.8 dB(A) with no pulsing or erratic RPM behavior. This is quieter than what we recorded on the older GP65 while being on par with the latest Alienware m15 R4, Aorus 15P, and Asus ROG Zephyrus G15 each with RTX 30 graphics.
If Cooler Boost (i.e., maximum fan mode) is enabled, fan noise will jump immediately to 57.2 dB(A) regardless of onscreen load. It's a massive increase in fan noise for not all that much performance gain as our Stress Test section below will detail.
Our test unit exhibits a slight coil whine of 26.8 dB(A) against a background of 24.7 dB(A).

Temperature
Surface temperatures are slightly cooler than on the GP65. When gaming, hot spots on the GP66 would reach 43 C and 48 C on the top and bottom of the base, respectively, compared to 46 C to 50 C on the GP65. Additionally, the hot spots are now located above the first row of keyboard keys for a cooler typing experience whereas the hot spots on the GP65 and even GS66 are closer to their keyboard centers.
(±) The maximum temperature on the upper side is 42.8 °C / 109 F, compared to the average of 40.4 °C / 105 F, ranging from 21.2 to 68.8 °C for the class Gaming.
(-) The bottom heats up to a maximum of 50 °C / 122 F, compared to the average of 43.2 °C / 110 F
(+) In idle usage, the average temperature for the upper side is 29.4 °C / 85 F, compared to the device average of 33.8 °C / 93 F.
(±) Playing The Witcher 3, the average temperature for the upper side is 33.4 °C / 92 F, compared to the device average of 33.8 °C / 93 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 25.8 °C / 78.4 F and are therefore cool to the touch.
(+) The average temperature of the palmrest area of similar devices was 28.9 °C / 84 F (+3.1 °C / 5.6 F).
Stress Test
When running Prime95 to stress the processor, CPU clock rates would boost to 4 GHz until hitting a core temperature of 88 C about 20 seconds later. Thereafter, clock rates would steadily fall and stabilize at the 3.2 to 3.4 GHz range in order to maintain a slightly cooler core temperature of 85 C. Enabling Cooler Boost mode would result in just very minor changes to CPU clock rates and temperature.
Running Prime95 and FurMark simultaneously would result in stable CPU and GPU temperatures of 82 C and 70 C, respectively. If Cooler Boost is on, core temperatures would drop by about 8 C each.
When running Witcher 3 to represent real-world gaming stress, core temperatures would stabilize in the 67 C to 76 C range if Cooler Boost is off and 63 to 69 C range if Cooler Boost is on. GPU clock rates would also increase slightly from 1680 MHz to 1755 MHz with a board power draw of 120 W to 130 W as advertised by the manufacturer. Running this same test on the GP65 would result in warmer CPU and GPU temperatures of 96 C and 79 C.
Running on batteries will limit performance. A Fire Strike test on battery power returned Physics and Graphics scores of 12004 and 6385 points, respectively, compared to 20842 and 28490 points when on mains.
| CPU Clock (GHz) | GPU Clock (MHz) | Average CPU Temperature (°C) | Average GPU Temperature (°C) | |
| System Idle | -- | -- | 39 | 41 |

Power Consumption
Overall power consumption is a lot closer to the GP65 than we had expected. For example, idling on desktop would consume between 13 W and 23 W which almost matches the GP65. Running Witcher 3 would average 191 W to be just 3 percent more than on the GP65 while offering a 40 to 45 percent boost in graphics performance. The gen-to-gen increase in performance-per-watt is impressive in this regard.
We're able to record a maximum draw of 216 W from the medium-sized (~15.3 x 7.3 x 3.0 cm) 230 W AC adapter.

Battery Life
Battery capacity has increased from 51 Wh on the GP65 to 65 Wh on the GP66. WLAN runtimes are now also much longer at just over 5 hours to be almost 1.5 hours longer than what we recorded on the GP65.
Maximum battery life, however, could have been better. Setting the system on Super Battery mode with brightness on minimum and the iGPU active would result in a total runtime of just 6.5 hours which isn't all that much longer than our WLAN settings.
The recharge rate from empty to full capacity is very slow at over 4 hours with the included AC adapter. We suspect that there is a charging bug because the estimated recharge time can also sometimes be inaccurate. Most other laptops will fully recharge in just 1.5 to 2 hours in comparison.
The battery will recharge even slower or not at all when running games. For example, playing Witcher 3 on AC adapter power at 20 percent battery charge for one hour would charge the battery to just 23 percent only (or +3 percent over the course of an hour).

Pros
Cons
Verdict
After two years with the GP65 design, the GP66 is a full revamp and a huge improvement overall. It may have gotten a bit larger gen-to-gen, but the size increase feels justified considering the jump in graphics performance, improvements to fan noise, cooler core temperatures, sleeker design, and longer battery life. Overall impressions are very close to the GE66 which is supposed to be the higher-end model.
The GP66 punches above its mid-range weight to be as good as many higher-end models.
There's a huge asterisk above "mid-range", however, as the GP66 is not cheap at the moment despite its classification. Prices range wildly from $2500 to $3000 USD to be in the high-end or enthusiast category. We're hoping that this is only a supply issue that can be resolved in short time as we can definitely see the GP66 becoming a popular model because of its above-average attributes all around.
Regardless of its high-end price, this is still a mid-range gaming laptop and so users should be aware of its shortcomings. There is no Thunderbolt, IR camera, or SD card reader, for example, and the display is dim relative to most other gaming laptops. The slow and inconsistent battery recharge rate certainly deserves a closer look. Until then, don't expect the battery to charge at a decent rate when gaming.
