Asus ROG Strix G18 (2025) G815LR 18" Intel Core Ultra 9 275HX 2.7GHz / Nvidia GeForce RTX 5070 Ti Laptop / 32GB RAM / 1TB SSD VS Lenovo Legion Pro 7i Gen 10 16"

Both laptops are positioned squarely as gaming machines, sharing a backlit keyboard, active cooling (no fanless design), and no weather sealing — all expected traits in this category. The most meaningful design divergence comes down to size and portability. The Asus ROG Strix G18 is an 18-inch chassis weighing 3420 g, while the Lenovo Legion Pro 7i Gen 10 is a 16-inch chassis at 2720 g. That 700 g difference is substantial in practice: carrying the ROG Strix daily in a backpack will be noticeably more taxing, making the Legion the more viable option for users who commute or travel frequently.

Footprint tells a similar story. The ROG Strix spans 399 × 298 mm versus the Legion′s 364 × 275.9 mm, meaning the Asus demands considerably more desk and bag space. Interestingly, despite its larger screen and greater overall volume (2734.7 cm³ vs 2671.4 cm³), the ROG Strix is actually thinner at 23 mm compared to the Legion′s 26.6 mm. This suggests Asus spread the internals across a wider footprint to achieve that slimmer profile, while Lenovo opted for a more compact but slightly taller chassis.

For design, the Legion Pro 7i Gen 10 holds a clear edge for anyone prioritizing portability and a smaller physical presence. The ROG Strix G18′s size is a deliberate trade-off — its larger chassis can better accommodate thermal headroom and a bigger display, but users pay for that with significantly more weight and desk real estate. If portability matters at all in the buying decision, the Legion wins this category outright.

Both laptops share the same 2560 × 1600 resolution and support up to 4 external displays, but the similarities end there. The most consequential difference is panel technology: the ROG Strix G18 uses an IPS LCD, while the Legion Pro 7i Gen 10 features an OLED panel. In practical terms, OLED delivers true per-pixel lighting control, meaning blacks are genuinely black rather than a backlit grey — this translates to dramatically higher contrast ratios and more vivid, accurate colors, which benefits both gaming visuals and content consumption alike.

Counterintuitively, the Legion′s smaller 16-inch screen actually produces a sharper image than the ROG′s 18-inch panel. Because both run the same resolution, the pixel density on the Legion reaches 189 ppi versus 167 ppi on the ROG Strix — a visible difference at normal viewing distances, resulting in crisper text and finer detail in games. The ROG Strix does push back with an anti-reflection coating, which the Legion lacks; in brightly lit rooms or near windows, this can meaningfully reduce eye strain and glare, partially offsetting the OLED′s luminance advantages in adverse lighting conditions.

On balance, the Legion Pro 7i Gen 10 holds the display edge for most use cases: OLED′s contrast and color superiority combined with higher pixel density make it the more premium panel. The ROG Strix′s anti-reflection coating is a genuine real-world benefit, but it compensates for environmental factors rather than closing the gap in intrinsic display quality. Users who work frequently under harsh lighting may find the ROG more comfortable, but for pure screen performance, the Legion wins this category.

At the CPU level, these two machines are effectively identical — same core configuration, same 5.4 GHz turbo clock, same 24 threads — so any performance gap comes entirely from the GPU and memory subsystems, and that gap is dramatic. The Legion Pro 7i Gen 10 delivers 31.8 TFLOPS of floating-point performance against the ROG Strix G18′s 17.04 TFLOPS, nearly doubling the raw GPU compute. This is not a marginal generational difference; it reflects a fundamentally higher-tier graphics card. The texture and pixel fill rates tell the same story, with the Legion pulling roughly 87% ahead on texture throughput and 67% ahead on pixel rate — translating directly to higher sustainable frame rates at demanding resolutions and settings.

The memory picture reinforces the Legion′s lead. Its GPU carries 24 GB VRAM versus the ROG′s 12 GB — a doubling that matters increasingly at high resolutions with modern titles and AI-assisted rendering features. On the system side, the Legion ships with 64 GB of DDR5 RAM running at 6400 MHz, compared to 32 GB at 5600 MHz in the ROG Strix. For memory-intensive workloads — game modding, video editing, large asset pipelines — this combination of greater capacity and faster bandwidth gives the Legion a meaningful real-world advantage. The Legion also steps up to PCIe 5, offering double the theoretical bandwidth to storage and peripherals compared to the ROG′s PCIe 4.

The Legion Pro 7i Gen 10 wins the performance category decisively and without caveat. Across every meaningful GPU metric, it outclasses the ROG Strix G18 by a wide margin, while also leading on RAM capacity, RAM speed, VRAM, and bus bandwidth. The ROG Strix is by no means a slow machine, but users prioritizing peak gaming and creative performance will find the Legion in a clearly higher tier.

The PassMark benchmark data here tells a straightforward story: both laptops score an identical 56,426 in the multi-core test and 4,723 in the single-core test. Since PassMark CPU scores are determined solely by the processor, this outcome is fully consistent with what the specs group revealed — both machines run the exact same CPU configuration, so producing matching scores is exactly what should be expected.

This is a complete tie for benchmarks, with neither product holding any advantage. Users seeking CPU differentiation between these two machines will not find it here or in real-world CPU-bound tasks.

Wired connectivity reveals a nuanced split rather than a clean winner. The ROG Strix G18 offers three USB-A 3.2 Gen 2 ports — all running at 10 Gbps — compared to the Legion′s mix of one Gen 2 and two slower Gen 1 USB-A ports. For users who regularly plug in high-speed peripherals like external SSDs, capture cards, or fast hubs, the ROG′s port quality across the board is a practical advantage. On the high-speed USB-C side, the ROG counters with two USB4 40 Gbps ports, while the Legion carries one USB4 40 Gbps alongside one Thunderbolt 4 port. Thunderbolt 4, while sharing the same 40 Gbps ceiling as USB4, brings a certified ecosystem of docks, eGPUs, and daisy-chaining support — making that single port more versatile for pro peripheral setups than an equivalent USB4 port.

Wireless is essentially a draw: both feature Wi-Fi 7 and Bluetooth 5.4, delivering identical range, latency, and multi-device handling capabilities. The one wireless differentiator is AirPlay support on the ROG Strix, which the Legion lacks — a meaningful convenience for users in Apple ecosystems who want to stream audio or video wirelessly to compatible devices.

Connectivity is closely contested. The ROG Strix G18 has the edge in sheer USB-A port quantity and quality, plus AirPlay. The Legion Pro 7i Gen 10 counters with Thunderbolt 4, which offers a richer certified accessory ecosystem. The better choice depends on the user′s peripheral setup: heavy USB-A users and Apple households lean toward the ROG, while Thunderbolt dock and eGPU users will value the Legion′s certified port more highly.

Battery capacity is the only meaningful variable here, and the gap is slim: the Legion Pro 7i Gen 10 carries a 99 Wh cell against the ROG Strix G18′s 90 Wh — a 9 Wh difference, or roughly 10% more stored energy. In absolute terms, both sit near the practical ceiling for airline-approved batteries (100 Wh), so neither can go meaningfully larger without hitting travel restrictions. Neither laptop uses MagSafe, making that a non-factor.

The Legion′s larger battery gives it a marginal edge in potential runtime, but the real-world impact is complicated by each machine′s power demands. The Legion houses a significantly more powerful GPU — as established in the performance group — which typically draws more power under load, potentially offsetting or even erasing its capacity advantage during gaming sessions. Under lighter workloads, the 10% capacity lead is more likely to translate into a tangible, if modest, runtime benefit.

On raw specs alone, the Legion Pro 7i Gen 10 edges this category by virtue of its larger battery. However, the margin is narrow enough, and the interplay with power consumption complex enough, that users should not expect a dramatic difference in day-to-day unplugged use between the two machines.

The Asus ROG Strix G18 (2025) and Lenovo Legion Pro 7i Gen 10 are both feature-rich laptops, but they differ in a few key aspects. Both have stereo speakers, a 3.5 mm audio jack, support for ray tracing, DLSS, and include two microphones. However, the Asus model includes Dolby Atmos support, while the Lenovo does not. Additionally, the Lenovo has voice command functionality and a compass, which the Asus lacks.

Neither laptop includes a stylus, fingerprint scanner, or 3D facial recognition. Both laptops have a front camera, accelerometer, and lack an optical disc drive. While both laptops lack a gyroscope and GPS, the Lenovo stands out by having a compass, which is absent on the Asus.

In summary, while both laptops offer similar core features, the Lenovo Legion Pro 7i adds voice command support and a compass, while the Asus ROG Strix G18 offers Dolby Atmos sound for a more immersive audio experience.

The Asus ROG Strix G18 (2025) and Lenovo Legion Pro 7i Gen 10 share several key specifications but differ in some important areas. Both laptops use the Intel Resizable BAR and have a clock multiplier of 27. Their GPU architecture is the same, utilizing Blackwell, and both support multi-display technology and 3D. The GPUs also share the same memory speed (25400 MHz) and OpenCL version (3), with both models supporting ECC memory. The maximum memory bandwidth is higher in the Lenovo, with 811.5 GB/s compared to the Asus’ 608.6 GB/s. Additionally, the Lenovo has a wider memory bus (256-bit) compared to the Asus’ 192-bit.

The shading units, texture mapping units (TMUs), and render output units (ROPs) are significantly higher on the Lenovo. The Lenovo has 10,496 shading units, 328 TMUs, and 128 ROPs, while the Asus has 5,888 shading units, 184 TMUs, and 80 ROPs. The GPU memory speed is also higher in the Lenovo at 2000 MHz compared to the Asus’ 1750 MHz. Both laptops have integrated graphics, but the Asus has a maximum RAM speed of 6400 MHz, which matches the Lenovo.
