Introduction:
It’s braxtech again with another laptop to share with you guys: the Lenovo Legion Slim 7 Advantage Edition! I had a lot of people ask me to directly compare this model to the Intel Slim 7i, which packs a 12700H and an RTX 3060 with a 1200p 165Hz display. This model, on the other hand, is sporting AMD’s (2nd) finest mobile offering, the 6900HX and the new thin-and-light GPU, the 6800S.
The 6800S has 8GB of VRAM and 32 Compute Units, and was intended to be used in thin & light laptops such as the G14 and the Slim 7 we have here today, while still providing a very capable gaming experience at 1080p and 1440p. The TGP of the 6800S within this laptop here is 90W, though AMD’s site says “up to 100W”, so things may change as drivers & firmware mature.
Chassis:
Now, before we get into the details, let’s quickly talk about the chassis and design itself. Just like the Intel variant, the Slim 7 AMD is incredibly rigid and very slim, as they share the same chassis. The keyboard deck and palm-rest areas have basically no flex when pressed on. The lid has some play if you twist it with enough force, but nowhere near offensive or worrisome in nature. The laptop can also be opened with one hand up to 180 degrees, and the hinges feel incredibly sturdy. The iron-sandblasted aluminum trim around the edges gives the device an ultra-premium feel and look, while also rounding out the corners, thus avoiding any sharp edges for your wrists.
In terms of physical dimension, the laptop is 14.08 x 10.24 x 0.67 inches, which is very similar in physical footprint to the Razer Blade 15, which is 13.98 x 9.3 x 0.67 inches. Weight-wise, the Slim 7 is about a half-pound heavier, coming in at 4.8 lbs when compared to the Blade, which is 4.4 lbs. Adding the power brick means an additional 1.5 lbs to the total.
Display:
One of the key differentiators between the Intel configuration available at Best Buy vs. this one is the display offering. While the Intel is running a 350-nit, 1920x1200p 16” IPS display at 165Hz, the AMD variant is using the same panel we all know and love from the Legion 5 Pro and Legion 7: 2560x1600p, 16”, 165Hz, IPS, 500 nits, FreeSync Premium, and 100% sRGB coverage, pre-calibrated via X-rite software. It’s bright, it’s color-accurate, and it’s fast. This panel is one of the nicest IPS displays in a gaming laptop on the market given its specs, and is still a great competitor to the OLED 240Hz displays that are available in the GE67HX. Specific details about the panel, its response time, and color gamut can be found in Jarrod’s video linked here.
Keyboard & Trackpad
Much of my commentary from my video on the Intel Slim 7i will remain relevant here, as they share the same chassis and trackpad. The keyboard layout is the same as the previous generation of Legion devices, still sporting the number pad on the right and the offset trackpad on the left. Lenovo has solved my one main gripe I had with the Legion 7 lineup of last year, which was shallow key travel. This year, the keyboard is much more satisfying to type on, and feels more like the Legion 5 Pro keyboard which had a few millimeters more travel comparatively. I think most people can get up to speed pretty quickly with this layout without much of a challenge. This one, however, does not offer RGB, just white backlighting in 3 stages of brightness.
The trackpad is the exact same size as last year’s Legion 7, coming in at 2.95 x 4.72 inches (or 72 x 120 millimeters) and is glass. I would say, however, it is held into place within the chassis in a more secure way. Both this unit and the Intel Slim 7i exhibited no wobbling or rattling when tapped lightly, and felt very stable when clicked. I owned a few 2021 Legions and all three units I had some “play” on the trackpad that created unnecessary noise, so this was a nice change for me specifically. Otherwise, it glides smoothly, handles gestures perfectly via Precision drivers, and gets the job done well.
Ports
For ports, the Slim 7 Advantage Edition is actually slightly worse than the Intel variant; it has one less USB-A port, no USB4 (yet, supposedly one of the Type-C ports will be updated via firmware) and only 1 NVMe 4.0 storage slot versus 2 in the Intel one, which is a real bummer in my opinion, especially for a gaming laptop where extra storage is basically essential these days. They are identical, otherwise.
AMD Version:
2x USB 3.2 Gen 1
2x USB-C 3.2 Gen 2 (support data transfer, Power Delivery 135W and DisplayPort 1.4)
1x HDMI, up to 8K/60Hz
1x Card reader
1x Headphone / microphone combo jack (3.5mm)

1x USB 3.2 Gen 2
1x USB-C 3.2 Gen 2 (support data transfer, Power Delivery 135W and DisplayPort 1.4)
1x Thunderbolt 4 / USB4 40Gbps (support data transfer, Power Delivery 135W and DisplayPort 1.4)
1x HDMI, up to 8K/60Hz
1x Card reader
1x Headphone / microphone combo jack (3.5mm)
Speakers
The Slim 7 lineup this year seems to be using the same set of speakers as the Legion lineup last year, having two 2W down-firing speakers at the front of the laptop on each side of the palm rests. Again, nothing game-changing, but also nothing particularly bad about them. They do seem to be tuned a bit better to my untrained ear over last year’s EQ settings, particularly with handling some bass. I think most users will be satisfied with how they sound, but not blown away or overly impressed.
Battery Life
One of the key differentiators between the 6000-series processors from the 5000-series processors from AMD is their optimized power consumption while doing lighter tasks, with the goal in mind to augment battery life on-the-go.
I had tons of people ask me about the 99 watt-hour battery on my Slim 7i video, and the answer unfortunately is still no, that battery configuration is still not available in the United States. For now, we get a 71 watt-hour battery, but you can likely buy the 99Wh one and swap it yourself down the line.
To preface, I did these tests in Lenovo’s Quiet mode, 60Hz refresh, and 50% brightness. At idle on desktop, the laptop had a discharge rate of -6.7W, which translates to about 10 and a half hours of battery in that state. I then tested YouTube playback with 1080p selected, which brought the system to roughly -8.3W after settling in. This converts to about 8 and a half hours of use for this purpose, which is impressive for a gaming laptop.
For mixed usage with multiple applications open, I’d expect around 6 hours (assuming average system power consumption is around 12W) with the stock 71WHr battery, which would go up another 2 hours if you upgraded the battery on your own.
Performance
Okay, moving onto performance metrics now. I have prepared three sets of data: one set completely stock, one set with a Curve Optimizer offset of -15 applied via UXTU (link in the description), and one more set with Curve Optimizer and a repaste with fresh PTM7950 and Gelid GC Extreme, video for that process here.
For Cinebench, there was a clear difference made by replacing the factory application of PTM7950 to a fresh batch, both in the single-run and the 10-minute run. The Slim 7, however, did still throttle on one core (both prior to the repaste and afterward) almost immediately, and sat in the mid-90s the entire run. Also, for some reason, HWiNFO was misreporting CPU package power in combined loads, so please refer to the CPU Core Power (SVI3 TFN) row in the screenshot. CPU core power would sustain itself around 70W after peaking around 86W at the start of the benchmark. Fan noise would quickly ramp up to around 48dB, which is still nicely under that 50dB threshold many reviewers use.
For those looking to tame the temperatures a bit, I’d recommend using a software like XTU or AATU to limit power to 60W, where temperatures sit in the mid-70s and you can still score over 14,000 points in R23 with a Curve Optimizer offset.
Next up we have Time Spy scores:
As you can see, repasting the device made little difference here, with the majority of the CPU performance improvement coming from adjusting its Curve Optimizer offset via UXTU. The 6800S is limited to 90W as I mentioned, and scores similarly to a 100W 3070/130W 3060 in terms of graphics. After some heatsoak, it sits around 68 degrees celsius for the latter half of the run, both stock and post-repaste with Gelid GC Extreme. Fan noise would quickly ramp up to around 48dB here as well.
Lastly, we have Shadow of the Tomb Raider’s built-in benchmark, ran at 1080p Highest preset:
Again, not really much of a difference made from the repaste nor from Curve Optimizer offset. Having an average of 115 FPS at these settings and resolution is pretty impressive, given that the GPU is limited to 90W. This result places the hardware combination right in line with most 3070 laptops, even with higher TGPs (125W). The 6800S once again hovered in the mid-to-high 60s, while the CPU ran quite warm, peaking around 91 degrees, but was mostly in the low-80s for the majority of the test.
Final Thoughts
The pros:
Excellent build quality and chassis rigidity
Great CPU efficiency for lighter tasks, thus leading to respectable battery life
Great IPS display that offers good color coverage, fast refresh rate, and high brightness
Respectable performance given its power constraints
The cons:
Even with a fresh repaste, the 6900HX ran quite hot in synthetic loads and CPU-heavy titles
No ability to tune or overclock the 6800S, as its unsupported by MSI Afterburner currently
At its current price point of $1949+tax, it has a lot of competition that outperforms it while only being marginally bigger/heavier, or offer similar performance for cheaper.
