ASUS ROG Strix G16 vs Lenovo Legion Pro 5i (RTX 5070 Ti)

The RTX 5070 Ti is the enthusiast sweet spot, and these are its two most popular 16-inch homes. The Strix G16 is the ROG enthusiast pick; the Legion Pro 5i is Lenovo's volume seller with a reputation for sensible pricing. Both are 240Hz-class machines with 12GB of GDDR7.

In this head-to-head we compare the ASUS ROG Strix G16 (RTX 5070 Ti) and the Lenovo Legion Pro 5i (RTX 5070 Ti) across gaming performance, display and design, UK pricing and value — and finish with a clear recommendation for different buyers.

At a glance: ASUS ROG Strix G16 (RTX 5070 Ti) vs Lenovo Legion Pro 5i (RTX 5070 Ti)

The Strix G16 offers the deeper enthusiast toolkit — Armoury Crate profiles, per-game tuning and the ROG community's wealth of shared settings. ASUS also tends to push BIOS and firmware updates faster.

The Legion Pro 5i is usually the cheaper of the two at UK retailers and Lenovo's Legion software is less intrusive. Build quality is consistently good, and the Legion line has one of the lowest complaint rates in the category.

Graphics and gaming performance

The ASUS ROG Strix G16 (RTX 5070 Ti) carries the RTX 5070 Ti: the enthusiast-value tier: 12GB of GDDR7 VRAM and strong 1440p performance. It is the GPU most buyers should compare everything else against, because it covers demanding games without flagship pricing.

The Lenovo Legion Pro 5i (RTX 5070 Ti) carries RTX 5070 Ti: the enthusiast-value tier: 12GB of GDDR7 VRAM and strong 1440p performance. It is the GPU most buyers should compare everything else against, because it covers demanding games without flagship pricing.

Both run the RTX 5070 Ti with HX-class Intel CPUs, so 1440p gaming performance sits in the same bracket. As ever with same-GPU comparisons, the specific SKU's power budget matters more than the badge — but neither brand is known for starving this tier.

When you read independent reviews of these machines, focus on three numbers: sustained GPU clock speeds under load (not just peak boosts), noise levels in decibels during gaming, and surface temperatures on the keyboard deck. Those three tell you more about the real-world difference between an RTX 5070 Ti machine and an RTX 5070 Ti machine than any specification table.

What reviews can't tell you is how a machine ages. Thermal paste dries, fans accumulate dust, and a laptop that reviewed quietly may run louder after two years of heavy use. Mitigate this by choosing machines with accessible cooling for cleaning where possible, using a cooling stand for desk sessions, and repasting only if you're comfortable — it usually isn't necessary within a typical ownership period.

Processor, memory and platform

The ASUS ROG Strix G16 (RTX 5070 Ti) pairs an Intel Core Ultra 9 HX-class with 32GB DDR5, while the Lenovo Legion Pro 5i (RTX 5070 Ti) pairs an Intel Core Ultra 9 HX-class with 32GB DDR5. For gaming, the GPU does most of the heavy lifting, but the CPU and memory platform determine how the machine handles everything else — multitasking, creative work and the CPU-heavy moments in open-world games.

Both machines here are modern platforms with DDR5 memory and fast NVMe storage as standard. If you do video editing, 3D work or software compilation alongside gaming, favour the stronger CPU and the larger memory configuration; if gaming is the priority, weight the GPU comparison above more heavily.

Display, design and everyday use

Displays: 16" WQXGA 240Hz on the ASUS ROG Strix G16 (RTX 5070 Ti), 16" WQXGA 240Hz on the Lenovo Legion Pro 5i (RTX 5070 Ti). For competitive play, prioritise refresh rate; for immersion and creative work, prioritise resolution, brightness and colour quality.

ROG styling is bolder; Legion styling is subtler and more living-room friendly. Both have good keyboards and 240Hz panels suited to competitive play. Neither is light, but both are movable.

UK price and value

UK pricing moves frequently — the figures above are listings seen in October 2026, and both machines are regularly discounted at major retailers. Check the live price before deciding: a £200 swing either way can flip the value verdict between two closely matched machines.

Warranty and returns: the fine print

In the UK, the Consumer Contracts Regulations give you 14 days to return most online purchases for any reason — use that window to properly test the machine, not just unbox it. Run your actual games, listen to the fans under load, and check for dead pixels and keyboard issues immediately. Problems found in the first 30 days give you strong rights to a repair, replacement or refund.

On warranties, the standard manufacturer cover is typically 12 months, with extended options varying wildly in value. For a £2,000+ laptop you intend to keep for years, a sensibly priced extension can be worthwhile; for budget machines, it rarely is. Accidental-damage cover is a separate product — worth considering honestly if the laptop will travel daily, skippable if it lives on a desk.

Verdict: which should you choose?

Tinkerers and ROG loyalists should take the Strix G16; everyone else should take the Legion Pro 5i if it is cheaper — which, at UK retailers, it frequently is.

Choose the ASUS ROG Strix G16 (RTX 5070 Ti) if its strengths — RTX 5070 Ti graphics, 16" WQXGA 240Hz display and 32GB DDR5 — match what you value most. Choose the Lenovo Legion Pro 5i (RTX 5070 Ti) if its combination of RTX 5070 Ti graphics and stronger value appeals more. Either way, buy the configuration with the display and memory you want — those are harder to change later than anything else.

Frequently Asked Questions

Which is better for gaming, the ASUS ROG Strix G16 (RTX 5070 Ti) or the Lenovo Legion Pro 5i (RTX 5070 Ti)?
It depends on the GPU tier and the specific configuration's power budget. Here, you're comparing RTX 5070 Ti against RTX 5070 Ti — the higher tier wins when both are well cooled. But two laptops with the same GPU can differ by a few percent based on wattage and thermals, so check independent reviews of the exact SKU rather than judging on the badge alone.
Which one is better value in the UK?
The Lenovo Legion Pro 5i (RTX 5070 Ti) was listed at pricing varies by configuration and retailer — check the live listing, against pricing varies by configuration and retailer — check the live listing for the ASUS ROG Strix G16 (RTX 5070 Ti). Value depends on live pricing at the time you buy — retailer discounts of £100–£300 are common on gaming laptops, so compare the current prices, not just these reference figures.
Can I upgrade the RAM or storage later?
It varies by model. Many 16-inch and 18-inch gaming laptops allow storage upgrades via spare M.2 slots, while RAM is increasingly soldered (LPDDR5X) on thin models and socketed (DDR5 SODIMM) on thicker ones. Check the manufacturer's service manual for the exact configuration before assuming.
Which has the better display?
The ASUS ROG Strix G16 (RTX 5070 Ti) offers 16" WQXGA 240Hz; the Lenovo Legion Pro 5i (RTX 5070 Ti) offers 16" WQXGA 240Hz. For competitive gaming, favour the higher refresh rate; for single-player immersion and creative work, favour resolution, brightness and panel technology (OLED and Mini-LED both beat standard IPS for contrast).
Should I wait for a sale or buy now?
If you need the machine now and the price is fair for the specification, buy it — waiting indefinitely for a hypothetical deal costs you the use of the machine. But if your need is flexible, set price alerts and give it two to four weeks: gaming laptops discount frequently, and patience is often rewarded with £150–£300 off. Black Friday and back-to-school periods are the traditional windows, though the best deal is simply a good price on the right machine, whenever it appears.
