MagyarMicrosoft Surface Laptop 3 15-inch Core i7 Review: Better with Ice Lake
The 15-inch Microsoft Surface Laptop 3 consists of four major SKUs in the following order from least expensive to most expensive: the Ryzen 5 3580U, Core i5-1035G7, Ryzen 7 3780U, and the Core i7-1065G7. We recently checked out the AMD Ryzen 5 configuration to see what the Surface Laptop can offer at its base level. Today, we'll be checking out the Intel Core i7 SKU to see what the Surface Laptop can do when at its supposed best.
We recommend checking out our existing review on the Surface Laptop 3 Ryzen 5 SKU to learn more about the chassis, keyboard, display, and other external features as these characteristics are identical between the Intel and AMD models. This review will instead focus on any internal differences between the Intel Core i7 and AMD Ryzen 5 SKUs including temperature, power consumption, battery life and of course, performance. Comparing our Core i7 SKU with the Ryzen 7 SKU would have made for more interesting results, but that will have to wait until a future date when we can get our hands on a Ryzen 7 unit.

Case
Connectivity
Port options are limited for a 15-inch laptop. The smaller Huawei MateBook X Pro, for example, comes with dual USB Type-C ports, Thunderbolt 3, and a USB Type-A port whereas the Microsoft laptop offers just one USB Type-C port with no Thunderbolt compatibility. An SD reader would have been appreciated especially for content creators and users on-the-go. You'll have to purchase the expensive Surface Dock if you want to exploit the docking capabilities of the Surface Laptop 3 to its fullest.
Communication
Intel SKUs come standard with the Intel AX201 for Wi-Fi 6 (802.11ax) connectivity whereas the AMD SKUs come with the slower Atheros/Qualcomm QCA6174 for Wi-Fi 5 connectivity only. The former can offer over two times the transfer rates of the latter should you happen to be one of the few users with a brand new Wi-Fi 6 router. Otherwise, WLAN performance won't feel any different during day-to-day loads as the main reason for owning a Wi-Fi 6 laptop right now is mostly for future-proofing. Note that the AX201 is functionally identical to the AX200 save for some hardware changes under the hood.

Keyboard and Touchpad
Display
Microsoft utilizes the same Sharp LQ150P1JX51 IPS panel across all of its Surface Laptop 3 SKUs. Our independent measurements show that key display characteristics are identical between the Intel and AMD options including brightness, contrast, colors, response times, and even their pulse-width modulation frequency. The competing Apple MacBook Pro 16 and Dell XPS 15 have brighter displays for better outdoor visibility.

Color space encompasses sRGB and approximately 62 percent of the AdobeRGB standard. Full AdobeRGB coverage is not available unlike on the XPS 15, Asus ZenBook Pro 15, or MSI Prestige 15.
Our Intel unit comes better calibrated out of the box when compared to our Ryzen unit. Intel says no post-calibration was performed on our test to suggest that certain Surface Laptop 3 SKUs may come better calibrated than others. Average grayscale and color DeltaE values are already low at just 1.3 and 0.89, respectively. Calibrating the display even further ourselves improves these values just marginally.

The display backlight flickers at 21370 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 51 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 21370 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 17900 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
Performance
The Core i7-1065G7 SKU is marketed as Microsoft's fastest Surface Laptop 3 configuration. It competes directly with the AMD Ryzen 7 3780U in the same way that the Core i5-1035G7 SKU competes with the Ryzen 5 3580U. Keep in mind that this same Intel Ice Lake CPU can also be found on the latest Surface Pro 7. Even if you don't game, the extra graphics horsepower from the integrated Iris Plus G7 should prove useful for graphics editors, accelerating video encoding or decoding, and external monitor support at higher resolutions.
Our unit ships with the Intel Command Center software pre-installed to replace the older Intel Graphics Control Center. The new application offers more visual settings with a revised UI. Future laptops powered by Intel graphics are expected to ship with Command Center as well.
LatencyMon shows no recurring DPC latency issues regardless of Wi-Fi in contrast to what we observed on our Ryzen unit.
Processor
As our 9th Core i7-1065G7 entry in our database, we're starting to see what the processor is capable of. Microsoft's implementation of the 25 W CPU appears to be better than most as its multi-thread CineBench score is 11 percent faster than the average i7-1065G7. Raw performance is thus 16 percent higher than the Ryzen 5 3580U and within just a few percentage points of the Core i5-9300H.
Performance sustainability is better than expected which explains the higher-than-average CPU benchmark scores. When running CineBench R15 Multi-Thread in a loop, for example, performance drop by just 6 to 7 percent over time compared to 17 percent on the similarly equipped Lenovo Yoga C940. Performance is also steadier when under such stressful conditions as shown by our graph below.
Another advantage over AMD is hardware-based AI acceleration. The problem is that most applications and even Windows itself have yet to exploit the emerging technology meaning that your day-to-day workloads will likely not benefit from the AI capabilities of Ice Lake, if at all.
See our dedicated page on the Core i7-1065G7 for more technical information and benchmark comparisons.
System Performance
PCMark scores are 4 percent to 21 percent higher than the Ryzen 5 SKU depending on the benchmark. Its Digital Creation score, for example, is merely 4 percent higher than the AMD to suggest that the real-world performance difference between Iris Plus and the Vega 8/9/10/11 series isn't as wide as Intel would like you to believe. Intel has its biggest advantage in the PCMark Essentials benchmark which tests how fast and smoothly the system can multi-task between web browsing and launching applications. The Intel chipset is likely better optimized for such day-to-day applications.
We experienced no software or hardware issues during our time with the test unit.

Storage Devices
Interestingly, our Intel SKU comes with a 256 GB Toshiba KBG40ZNS256G NVMe SSD in contrast to the 256 GB SK Hynix BC501 in our Ryzen 5 SKU to suggest that Microsoft is sourcing multiple suppliers for its Surface Laptop 3 series. It's therefore a gamble as to which SSD you will actually end up purchasing.
The Toshiba drive outperforms the SK Hynix drive. AS SSD shows sequential read and write rates of 1755 MB/s and 818 MB/s, respectively, compared to 1122 MB/s and 514 MB/s on our Ryzen 5 SKU. Though an improvement, transfer rates are merely average when compared to the Apple SSD or Lite-On SSD as found on the Apple MacBook Pro 16 or Razer Blade Stealth. It's disappointing to see Microsoft cut corners here on its premier laptop series.

GPU Performance
3DMark scores show the integrated Iris Plus GPU to be on par with the RX Vega 9 in the Ryzen 5 3580U at worst or about 15 percent faster at best. In real-world gaming scenarios, however, the Intel GPU has the potential to be much faster. Rocket League and F1 2019, for example, can each run up to 40 percent faster than the RX Vega 9 while other games like Overwatch and Shadow of the Tomb Raider are neck-to-neck between the Intel and AMD SKUs. If you plan on playing popular titles like Fortnite or Rocket League, then you may want to consider the Intel Iris Plus options to maximize performance. 3DMark continues to be a poor indicator of real-world gaming performance for the Intel Iris Plus and AMD RX Vega series of integrated GPUs.

Emissions
System Noise
We had anticipated some differences in fan noise between the Intel and AMD SKUs, but that is not the case. Our microphone measurements when running 3DMark 06, Witcher 3, or Prime95 all resulted in essentially the same results as our AMD configuration last month. The Surface Laptop 3 is mostly inaudible during low to medium loads with fan noise picking up noticeably only when running higher loads like gaming for extended periods.
Our test unit exhibits slight coil whine when placing an ear near the keyboard keys. The electronic noise is minor enough to not be an issue.

Temperature
There are no major differences in surface temperature development between the Intel and AMD SKUs in spite of any performance differences. Running both Prime95 and FurMark simultaneously results in hot spots of 41 C to 46 C on the Intel compared to 42 C to 50 C on the AMD. Be prepared for very warm WASD keys when gaming or running high loads in contrast to most gaming laptops.
The lack of any ventilation grilles on the bottom panel means you can use the laptop on your lap without blocking airflow. On the other hand, the back half of the laptop will be warmer than usual.
(±) The maximum temperature on the upper side is 41.8 °C / 107 F, compared to the average of 34.2 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(-) The bottom heats up to a maximum of 45.6 °C / 114 F, compared to the average of 36.7 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 21.6 °C / 71 F, compared to the device average of 29.5 °C / 85 F.
(±) Playing The Witcher 3, the average temperature for the upper side is 32.2 °C / 90 F, compared to the device average of 29.5 °C / 85 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 29 °C / 84.2 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 27.7 °C / 81.9 F (-1.3 °C / -2.3 F).
Stress Test
We stress the system with synthetic loads to identify for any potential throttling or stability issues. When running Prime95, CPU clock rates can be observed running at 3.5 GHz for the first 20 seconds or so until hitting a core temperature ceiling of 85 C. Thereafter, clock rates drop to the 2.6 - 2.7 GHz range to maintain a cooler core temperature of 75 C. Both clock rates (2.7 GHz vs. 2.4 GHz) and core temperature (77 C vs. 66 C Tctl/Tdie) stabilize at higher values on the Core i7 when compared to the Ryzen 5 3580U SKU. Keep in mind that HWiNFO reports core temperatures differently between Intel and AMD CPUs and so these temperature differences may not be directly comparable here.
Running Witcher 3 is more representative of demanding real-world loads. Both GPU clock rates and core temperature are again higher on our Intel SKU when compared to the Ryzen 5 SKU (1050 MHz vs. 800 MHz and 73 C vs. 58 C) according to GPU-Z.
Running on battery power will not limit performance meaning users can get full system performance if away from an AC outlet. A Fire Strike run on batteries returns Physics and Graphics scores of 12008 and 3060 points, respectively, compared to 11959 and 3062 points when on mains.
| CPU Clock (GHz) | GPU Clock (MHz) | Average CPU Temperature (°C) | |

Energy Management
Power Consumption
Idling on desktop demands between 4 W and 8 W compared to 3 W and 7 W on our Ryzen 5 SKU. However, we suspect that differences in background activity are likely responsible for the discrepancy especially at these low rates. The more interesting power consumption numbers come in when gaming as the Intel laptop consumes just under 42 W on average compared to 45 W on the Ryzen 5 SKU even though the Intel laptop offers better gaming performance all-around. In other words, Intel has the superior performance-per-Watt over AMD.
We're able to record a maximum draw of 64.4 W from the small (~9 x 5 x 2.5 cm) 65 W AC adapter when running Prime95 and FurMark loads. However, this only lasts for about 20 seconds before consumption drops and stabilizes at 43 W due to thermal reasons.

Battery Life
Battery capacity is small for a 15-inch laptop at just 45 Wh. Even the Huawei MateBook X Pro, for example, comes with a higher capacity 57 Wh battery. Runtimes are still respectable at just over 8 hours of real-world WLAN use to be almost an hour shorter than the slower Ryzen 5 SKU.
A noteworthy find is that idling on desktop at the lowest possible settings and brightness level will last about 35 hours before needing to recharge. While an unrealistic scenario, it shows that users can stretch out the battery for longer than usual if needed.
Recharging from empty to full capacity takes about 2 hours. Recharging via USB Type-C with our 130 W Dell or 65 W Lenovo AC adapters also works.

Pros
Cons
Verdict
The main advantages of our Core i7 SKU versus the Ryzen 5 SKU include Wi-Fi 6 compatibility, faster storage performance, faster CPU performance, integrated AI acceleration, faster gaming performance, and higher performance-per-Watt. Other aspects like the display, WLAN battery life, surface temperature, and fan noise are either the same between them or nearly identical.
While it's unsurprising that our Core i7 SKU is able to outperform our cheaper Ryzen 5 SKU, it's the margin that we're more interested in. Raw CPU performance, for example, isn't all that much faster meaning you shouldn't be choosing Intel over AMD based purely on processor horsepower. Gaming performance is also largely inconsistent with some games running better on Intel and others being neck-to-neck. Meanwhile, AI acceleration continues to be a novelty for most office users as of this writing since it has no direct influence on common day-to-day tasks. Intel can really leverage its advantages over AMD in the field of AI, but that won't mean very much to consumers if applications aren't optimized to exploit AI acceleration in the first place.
In short, the day-to-day performance differences between the Surface Laptop 3 Core i7 and Ryzen 5 SKUs are smaller than anticipated especially when you consider the price premium that Microsoft is charging for its Intel SKUs. If you're a power user who wants the best that the Surface Laptop can offer, then the Intel options are a no-brainer. Otherwise, you'd be hard-pressed to tell the difference between an Intel and AMD Surface Laptop 3 if your workload primarily consists of word processing, web browsing, or video streaming.
