Lenovo Yoga Slim 7 14 laptop review - With Nvidia GPU against AMD
We already reviewed the Lenovo Yoga Slim 7 14 with a current Ryzen 4800U processor from AMD, but there's also a model with a combination of an Intel CPU and a dedicated Nvidia GPU. This is the Yoga Slim 7 14IIL05 and is equipped with the Intel Core i7-1065G7, the GeForce MX350, 8 GB of RAM, and a 512 GB NVMe SSD. The Intel model is a bit more expensive in terms of price, but the AMD models are hardly available at the time. We now want to clarify what differences there really are in everyday life apart from the price. Since the Ryzen 7 4800U has been very hard to get so far, we will also compare the CPU and GPU performance with the Ryzen 7 4700U, which is also available for the Yoga Slim 7.

Case - Intel and AMD identical
Besides the manufacturer stickers on the palm rest, the case doesn't differ from the Yoga Slim 7 14 with the AMD processor (reviewed here). There's also only a marginal difference in weight, but you won't notice it even if you compare them directly. The only visible difference is the power adapter, because the power consumption increases due to the additional Nvidia GPU, and you get a 50-gram heavier 95-watt power adapter instead of the 65-watt model.
Connectivity - Intel version with Thunderbolt 3
When it comes to the ports, the Intel model of the Yoga Slim 7 14 has a big advantage, as one of the two USB-C ports supports Thunderbolt 3. The Intel model also offers an HDMI 2.0b output, so that 4K monitors can be run at 60 Hz.

Display - Yoga with reflective 1080p panel
As with the AMD model, a matte Full HD display is built in, but this is a panel from another supplier. As with the ThinkPad models, Lenovo also uses different suppliers for the Yoga. On our current test device, however, the reflective display is significantly dimmer at around 290 cd/m², which is particularly noticeable in bright rooms and, of course, outdoors as well. Nonetheless, the subjective impression left by the display is good and benefits from the very low black value, which is why the contrast ratio is also excellent at 1,700:1.

For the display measurements, we use the professional CalMAN software together with the X-Rite i2 Pro 2 spectrophotometer. Out of the box, there's a slight blue tint in the grayscales in combination with a color temperature that is a bit too cool. Otherwise, the deviations are not particularly high and only individual values are above the important limit of 3.
With our calibration (the profile is available above to download freely), we can make use of the panel's full potential and correct the color tint. In addition, all color deviations are also below 3. Together with the almost complete sRGB coverage, the Yoga Slim 7 is, therefore, also suitable for editing images and videos.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8687 (minimum: 5 - maximum: 343500) Hz was measured. |
The reflective display is problematic outdoors, and you must try to avoid reflections from light sources or bright objects. However, working comfortably is only possible in the shade. But there is no criticism when it comes to the viewing-angle stability of the IPS panel.
Performance - Yoga Slim 7 with Intel and Nvidia
Processor - Intel is clearly outperformed
Our test device contains the Intel Core i7-1065G7 quad-core processor; its Ice Lake architecture is manufactured in a 10 nm process. Its four cores (eight threads) run at a maximum of 3.5 GHz (1 and 2 cores at a maximum of 3.9 GHz). The cooling of the Yoga Slim 7 also handles the processor quite well and allows a prolonged power consumption of about 28 watts (31 watts for a short time), which is sufficient for 4x 2.9 GHz.
In terms of single-core performance, the opponents are still almost on par, but when it comes to the usage of all cores, the Intel CPU doesn't stand a chance against the new AMD Ryzen chips; it's outperformed by both the Ryzen 7 4800U as well as the more widespread Ryzen 7 4700U.
CPU performance is practically identical on battery power.

Graphics card - Intel Iris and Nvidia MX350
In everyday use, the integrated Iris Plus Graphics G7 takes care of graphics output. Thanks to the powerful video decoder, the reproduction of high-resolution videos is no problem. If you need more performance, for example when playing games, the system automatically switches to the dedicated Nvidia GeForce MX350.
The comparison with the new integrated GPUs from AMD is especially interesting here. In comparison with the RX Vega 8, the dedicated MX350 can only narrowly assert itself in the synthetic benchmarks, and it leads by only about 10-15%. In comparison with the RX Vega 7 of the Ryzen 7 4700, the lead of 26-47% is much larger in contrast. In addition, the performance yield of the MX350 is very good since it's just above the average values that we have for this GPU in our database.
The GPU's performance remains stable even under prolonged load, because the Yoga Slim 7 passes the demanding Time Spy stress test without any problems at 99%. GPU performance drops by about 15% on battery power.

Gaming performance
When it comes to actual gaming performance, the dedicated GeForce GPU can stand out a bit more and is, therefore, better suited for gaming. Overall, however, we're still dealing with a low mid-range graphics card here, so that only medium details are often possible with more demanding titles. Only older or less complex titles can be played at high details without problems.

Emissions - The Yoga gets quite loud
Noise emissions
The fan is usually very quiet or disabled for simple tasks. But as soon as you put load either on the CPU or the GPU, it immediately jumps to the maximum level and also becomes very clearly audible at 41.5 dB(A); as a result, it's one step away from becoming annoying. Considering performance in particular, we would've expected a better result here. The AMD version of the Yoga Slim 7 has a clear advantage here too. At least we couldn't hear any coil whine.

Temperature
The Intel model clearly has the disadvantage when it comes to surface temperatures too; the additional dedicated graphics card is simply an additional processor that needs to be cooled. As a result, we register over 45 °C (~113 °F) at several measuring points under load, both at the top and bottom.
During the stress test, the graphics card's clock speed drops from just under 1,600 to 1,350 MHz, but the CPU cores undergo a sharper decline from 2.4-2.5 GHz to 1.4-1.5 GHz (14 watts). But there are no limitations after the stress test.
(-) The maximum temperature on the upper side is 47 °C / 117 F, compared to the average of 36.9 °C / 98 F, ranging from 21.1 to 71 °C for the class Multimedia.
(-) The bottom heats up to a maximum of 56.3 °C / 133 F, compared to the average of 39.2 °C / 103 F
(+) In idle usage, the average temperature for the upper side is 25.8 °C / 78 F, compared to the device average of 31.3 °C / 88 F.
(±) Playing The Witcher 3, the average temperature for the upper side is 36 °C / 97 F, compared to the device average of 31.3 °C / 88 F.
(+) The palmrests and touchpad are reaching skin temperature as a maximum (32.3 °C / 90.1 F) and are therefore not hot.
(-) The average temperature of the palmrest area of similar devices was 28.8 °C / 83.8 F (-3.5 °C / -6.3 F).

Energy management - On par in terms of battery life
Energy consumption
The additional graphics card also has a negative effect on power consumption. Especially under load, power consumption is significantly higher, but the two versions are almost equal in idle usage. The value settles at around 60 watts during the stress test. The included power adapter (95 watts) is completely adequate.

Battery life
The two versions aren't that different either when it comes to our WLAN test, and you can expect about 10 hours. If we increase the brightness to the maximum, battery life is reduced by one hour. Especially when playing videos, however, the test device leaves a good impression with a runtime of over 13 hours.

Pros
Cons
Verdict - The Yoga Slim 7 with AMD is the better all-rounder
Lenovo doesn't make many changes when it comes to the AMD and Intel versions of its Yoga Slim 7. Apart from the Thunderbolt 3 port in the Intel Yoga, both the case and the connectivity are identical. The Chinese manufacturer installs an additional dedicated GPU from Nvidia so as to provide a somewhat better graphics performance. This offers a slight advantage, especially when playing games, but also leads to increased emissions. The fan speed increases very quickly under load and gets comparatively loud as well. In addition, the surface temperatures are higher than on the AMD model.
The CPU performance is not bad for a quad-core processor, but AMD is very clearly ahead with its current Ryzen processors, especially if you can make use of the additional computing cores. Other advantages are the lower temperatures and the quieter fan noise.
With the Intel/Nvidia combination, the Yoga Slim 7 14 has an advantage when it comes to gaming performance, but overall, the AMD model is the much better all-rounder.
The Yoga Slim 7 with the Ryzen 7 4800U made a good impression on us in the test, but the model with this processor is currently very difficult to get due to supply bottlenecks. Alternatively, the Slim 7 14 is also available with the somewhat weaker Ryzen 7 4700U and the slower Vega 7 iGPU. If you want to game a lot, you can take a calm look at the Intel model of the Yoga Slim 7 14, but the AMD models are the better all-rounders and thus the better choice for many users.
