Intel Core Ultra 7 256V performance debut: Lenovo Yoga Slim 7 15 Aura laptop review

Unveiled just a short month ago at IFA 2024, the Yoga Slim 7 15 Aura is now available to be one of the first Lenovo laptops with Intel's new Lunar Lake platform. The Aura series was designed in collaboration with Intel to imply that all Aura models are expected to ship with Intel processors only and be Co-Pilot+ ready.
Our test unit comes with the Core Ultra 7 256V CPU, integrated Arc 140V graphics, 1 TB SSD, and 15.3-inch 2.8K IPS touchscreen for approximately $1380 USD. The only other SKU available at the moment differs only in RAM capacity.
Alternatives to the Yoga Slim 7 15 Aura include other upper-end multimedia laptops like the Asus Zenbook S16, HP Spectre x360 16, or Dell XPS series.

Case — MIL-STD-810H Certified
The Yoga Slim 7 15 Aura shares the same aluminum materials and gray color scheme as the rest of the Yoga series and most IdeaPad Pro models as well. While the former is understandable, the latter means that it's becoming increasingly difficult to visually differentiate between many Lenovo laptops. The dull and gray unicolor design could use some sprucing up or embellishing to help make the Aura series stand out from the rest of the pack.
Chassis rigidity is otherwise excellent and comparable to the Yoga Pro 7 14 since the Aura borrows many of the same external design elements. We still find the HP Spectre to be stronger overall, however, as the Aura flexes and teeters slightly more along its base and hinges, respectively.
The unique 15.3-inch screen size allows the Aura to be both smaller and lighter than most 16-inch multimedia laptops by a few hundred grams. One of its closest competitors in the 15-inch space is the Snapdragon-powered Asus VivoBook S 15 which manages to be a bit lighter but not as thin as our Lenovo.
Connectivity
Port options are identical to the Yoga Pro 7 14 albeit rearranged for the better. The two USB-C ports are no longer next to each other as they are now on both sides of the laptop for more freedom in terms of charging orientation.
Alternatives like the XPS 14 or Spectre x360 16 don't offer many more port options than our Aura despite their size differences.
Communication
Webcam
The 2 MP webcam may be decent, but it's starting to show its age now that higher resolution 5 MP and 9 MP webcams are becoming common. Competing models from the HP Spectre or Dragonfly series offer both sharper images and more webcam features than our Lenovo for those who do a lot of video conferencing.
Both IR and a digital camera kill switch come standard.

Maintenance
Sustainability
Lenovo claims 50 percent recycled aluminum for the bottom cover, 90 percent post-consumer plastic for the AC adapter, and 50 percent post-consumer plastic for the keyboard. The manufacturing is also certified carbon neutral.
The packaging consists of cardboard and paper to be 100 percent plastic free.
Accessories And Warranty
There are no extras in the box beyond the AC adapter and paperwork. Th usual one-year limited manufacturer warranty applies if purchased in the US.
Input Devices
Keyboard
key layout and icons are the same as on the Yoga Pro 7 14 G9 down to even the two-level white backlight. Key feedback also appears to be identical as clatter is still relatively loud especially when striking the Space key. The typing experience is otherwise satisfactory and better than on the XPS 15 if you prefer louder and firmer keys.
Touchpad
The clickpad (13.5 x 8 cm) is larger than the one on the Yoga 7 16 G8 (13 x 8 cm) while being smaller than on the Yoga Pro 9i 16 G8 (15 x 9.5 cm). Glide is smooth but with some sticking at slower speeds to reduce accidental sliding when clicking. Feedback when pushing down on the surface is also sharp relative to the quiet clatter for a satisfying feel.
Display — Pre-Calibrated For P3 Colors
The Yoga Slim 7 15ILL9 Aura is one of the few 15.3-inch laptops in the market as most models in the 15.x-inch category have either moved up to 16.0-inch or moved down to 15.0-inch. Its IPS touchscreen is nonetheless of excellent quality with full DCI-P3 colors, HDR400 support, and a 120 Hz refresh rate whereas most other IPS panels are sRGB only with no HDR. These attributes help keep the Lenovo competitive against other multimedia laptops where OLED is becoming dominant.
Unfortunately, our unit would exhibit refresh rate issues. The screen would occasionally change refresh rates during use even when set to 120 Hz and with dynamic refresh rate disabled. The mouse cursor would noticeably skip frames for seemingly no reason. Performance doesn't appear to be affected, but the user experience becomes jittery and not as smooth as what 120 Hz is capable of. We're unsure if this is a bug with the model or just a specific problem on our test unit.

The display comes pre-calibrated at factory and our independent X-Rite colorimeter can confirm as much with low grayscale and color deltaE values of just 1.5 and 2.47, respectively, against the P3 standard. An end-user calibration is therefore not necessary for most buyers.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8327 (minimum: 5 - maximum: 343500) Hz was measured. |
At about 500 nits maximum, the display is slightly brighter than competitors like the Asus Vivobook S 15 or Spectre x360 16. The advantage is not enough to make a noticeable difference when outdoors where glare is still unavoidable especially considering the glossy screen. Viewability is acceptable at best when under shade.
Performance — Efficiency-First Approach
Testing Conditions
We set both Windows and Lenovo Vantage to Performance mode prior to running the benchmarks below. Vantage has been redesigned yet again and so the locations of many settings have changed when compared to other Yoga or IdeaPad laptops. The power profiles in particular are annoyingly buried under two or three submenus. Lenovo has added a "mode" hotkey to more easily launch the power profile menu.
Processor
We weren't particularly impressed by the performance of the Core Ultra 7 258V and the same can be said for the Core Ultra 7 256V which is essentially the same processor but with half the on-package RAM. Even so, multi-thread performance according to multiple benchmarks still comes out to be almost 20 percent faster than the Core Ultra 7 258V in the Zenbook S 14 UX5406. Our sample size of Lunar Lake laptops is still quite small at the moment and we're already seeing relatively wide performance discrepancies between various models. This suggests a wider power range for Lunar Lake CPUs when compared to previous generation processors in order to fit a wider range of laptop sizes.
While the aforementioned performance boost over our original Core Ultra 7 258V sample from Asus is welcomed, older H-series options are still sufficiently faster by about 15 to 30 percent including the Ryzen 7 7840HS or Core Ultra 7 155H. The new Core Ultra 7 258V or Ultra 7 256V is therefore closer in performance to the Core 7 U or Ryzen 7 U families.
The integrated NPU supports Co-Pilot+ unlike on the outgoing Meteor Lake platform. CineBench R15 results are not included below as there is currently a compatibility bug between the benchmark and the Lunar Lake platform.

Stress Test
The CPU would boost to 3.5 GHz and 39 W when initiating Prime95 stress on Performance mode. When core temperature reaches 90 C about 40 seconds later, the CPU would drop to 3.1 GHz and 30 W in order to maintain a cooler core temperature of 79 C as shown by the screenshot below. Performance is reduced further to just 2.6 GHz and 20 W if running on Balanced mode instead. Either way, maximum Turbo Boost is relatively limited as to be expected from a non-Core-H series processor.
The ZenBook S 14 and its Core Ultra 258V runs at a lower wattage than our Lenovo which explains the performance deficit between them as noted above.
Core temperature would stabilize at just 66 C when running Cyberpunk 2077 to represent typical gaming stress. This is relatively cool all things considered; the Yoga 9 2-in-1 14IMH9, for example, would stabilize at a warmer 74 C under similar gaming conditions.
CPU Clock (GHz) | GPU Clock (MHz) | Average CPU Temperature (°C) | |
System Idle | -- | -- | 50 |
Prime95 Stress (Balanced mode) | 2.6 | -- | 65 |
Prime95 Stress (Performance mode) | 3.1 | -- | 79 |
Prime95 + FurMark Stress | 2.4 | 1500 | 71 |
Cyberpunk 2077 Stress | 1.4 | 1400 - 1950 | 66 |
System Performance
PCMark results are decent but largely underwhelming due to the average processor performance mentioned above. This can be seen in the Essentials and Productivity subtests where our Aura would fall well behind the AMD-powered Asus Zenbook S16 and its more capable Zen 5 CPU.
AIDA64 Memory results are some of the best of any laptop thanks to the fast LPDDR5x-8533 RAM. The on-package memory is one of the highlights and distinguishing factors of Lunar Lake.

DPC Latency
4K60 video playback is flawless with no dropped frames recorded during a 60-second window. This is in contrast to the AMD-powered OmniBook Ultra 14 where frame drops would occur in consistent intervals.
LatencyMon is incompatible with the new Lunar Lake CPU much like on the Zen 5 series.
Storage Devices
Our test unit ships with a 1 TB Western Digital SN740 SDDPMQD whereas most other Yoga models typically come with Samsung or SK Hynix SSDs instead. Transfer rates from our WD is reliable at ~5200 MB/s with no signs of performance throttling. Nonetheless, the more common Samsung PM9A1 is still the faster drive by almost 2000 MB/s.
Keep in mind that full-length M.2 2280 SSDs are not supported on this machine despite the relatively spacious 15.3-inch form factor.

GPU Performance — Strong 3DMark Scores, Poorer Gaming Scores
3DMark results are excellent with results that are well ahead of the outgoing Iris Xe 96 EUs and just slightly above the Arc 8. Scores are even ahead of the competing Radeon 890M by a few percentage points, but performance in actual games is a different story as our next section below will show.

Gaming Performance
The Radeon 890M-powered OmniBook Ultra 14 would outperform our Aura in 9 out of 10 tested titles oftentimes by as much as 30 to 40 percent in titles like Cyberpunk 2077. The only exception is in DOTA 2 Reborn where the new AMD GPU is currently exhibiting rendering issues.
The wide performance disadvantages when gaming do not reflect our 3DMark results above where the Arc Graphics 140V is more competitive against the Radeon 890M. This is because the CPU in the OmniBook Ultra 14 is much more powerful than the Core Ultra 7 256V to suggest that CPU bound scenarios could be common on Lunar Lake laptops.
F1 22 still crashes on Ultra settings much like on PCs with Arc 8.

Emissions
System Noise
Fan noise is almost always quiet and even almost inaudible in most day-to-day scenarios. Web browsing or video playback would induce a noise of just 26 dB(A) against a silent background of 23 dB(A). Pulsing behavior is also nonexistent.
The story changes when running more demanding loads like games where fan noise can reach over 34 dB(A). Though not distracting by any means, it's still a bit louder than what we recorded on the Zenbook S 14 with the Core Ultra 258V. The generally faster performance of our Lenovo therefore comes at the cost of higher consumption and louder fans.
We're able to record a maximum fan noise of 44.3 dB(A) when the CPU is at 100 percent utilization on both Performance mode or Balanced mode.

Energy Management
Power Consumption
Overall consumption is low and comparable to many Core U-series laptops like the IdeaPad Slim 5 16 even though our Core Ultra 7 256V edges out most Core-U options in raw benchmarks. Performance-per-watt is therefore decently higher than Meteor Lake-U to be more competitive against the up-and-coming Snapdragon X Plus. Running Prime95, for example, consumes about 50 percent more power than the Snapdragon-powered VivoBook S 15 (52 W vs. 35 W) while offering roughly 50 percent faster multi-thread performance in the process.
Consumption is also generally higher than the ZenBook S 14 with the Core Ultra 7 258V which aligns with the higher processor performance from our Lenovo.
Higher loads like games demand about 49 W to be much more efficient than Iris Xe-powered laptops but still well behind Radeon 890M-powered alternatives like the ZenBook S16.
We're able to record a maximum draw of 67 W from the small (~9 x 4.6 x 2.7 cm) 65 W USB-C AC adapter when the CPU is at 100 percent utilization.

Battery Life
The 70 Wh battery is smaller than many other 15-inch laptops, but the efficiency of Intel's new CPU series still shines through. WLAN runtime can last for over 17 hours to be several hours longer than competing models from HP, Dell, or Asus running on older generation processors. Runtimes are even better than the Snapdragon-powered Asus VivoBook S 15.
Charging from empty to full capacity is slower than expected at around 2 hours even with Lenovo Rapid Charge enabled. We repeated the test several times but results would not improve. Rapid Charge is available on many Lenovo laptops where charging times can be reduced to just ~45 minutes and so the unusually slow charging rate on our Yoga test unit could be a bug.

Verdict — Lenovo's Best MacBook Air 15 Challenger
Intel developed Lunar Lake with efficiency as a top priority and the results reflect this. Battery life is one of the longest of any Windows laptop to be competitive against the MacBook Air 15 while core temperatures under load would remain low relative to other multimedia laptops. Fan noise, thinness, and portability indirectly benefit from this efficiency-first approach.
Drawbacks to the new Lunar Lake CPU revolve around performance. It's mediocre in the sense that it doesn't offer very much over last year's Core-U or Arc 8 options. Users who want a performance-first and efficiency-second laptop will find more value from older Core Ultra 7 155H models. The latest mobile Zen 5 options like the HP OmniBook Ultra 14 also fall into this latter category.
Travelers who find 14-inch subnotebooks too small and 16-inch multimedia laptops too large will have a lot to like about the 15-inch Yoga Slim 7 Aura. However, power users should stick to Core H and Zen 5 alternatives.
Because of the above advantages and disadvantages, the Yoga Slim 7 15 Aura is best for mobile users or travelers who can fully exploit the MacBook Air-like size and long runtimes made possible by Lunar Lake. Otherwise, users who have frequent access to AC outlets may want more powerful alternatives like the Asus ZenBook S 16 or Lenovo Slim Pro 9i 16IRP8 which tend to offer superior performance-per-dollar.
