Dell XPS 15 7590 Review: 4K UHD, i7-9750H, GTX 1650 (2026)

Introduction

The Dell XPS 15 7590 (XPS7590-7565SLV-PUS) is a 2019 legacy device being sold new at $1399 in April 2026, a market defined by 20-40% AI-driven price hikes and a shift to Copilot+ PC standards. This 7-year-old chassis is powered by a 9th Gen Intel Core i7-9750H and GTX 1650, specs that fail modern AI readiness thresholds entirely.

At the same $1399 price point, you can purchase a renewed Apple MacBook Pro 14 M1 Pro ($1099) with 2x the CPU performance and 3x the battery life, or a Lenovo Legion 7 15IMH05 ($1099) with 2.5x better gaming performance. This review breaks down why this legacy XPS 15 is a poor value in 2026.

Chassis & Ergonomics

Build quality is excellent: the CNC-machined aluminum chassis and carbon fiber composite palm rest feel premium and durable, matching the fit and finish of 2026 XPS 15 models. The keyboard has 1.3mm key travel with good tactility, but no per-key RGB or dedicated media keys. The Precision glass trackpad is large and responsive, though smaller than modern XPS 15 trackpads.

Port selection is mixed: the two Thunderbolt 3 ports support 40Gbps data and display output, but are not backwards-compatible with USB4/TB4 peripherals. The inclusion of a USB Type-A port, HDMI 2.0, and full-size SD card reader will appeal to legacy users, but there are no modern high-speed ports. The 720p webcam is terrible by 2026 standards (modern laptops use 1080p or 4K webcams), and the bottom-firing stereo speakers are adequate but lack the bass of modern quad-speaker setups.

Technical Specifications

Performance Analysis

The i7-9750H is a 2019 14nm 6-core/12-thread CPU, 7 generations behind 2026's Lunar Lake/Arrow Lake silicon. In Cinebench R23 multi-core testing, it scores ~8,500 points, compared to ~12,000 for an entry-level Core Ultra 5 125H and ~18,000 for the M1 Pro in the price-comparable renewed MacBook Pro 14.

Thermal management is poor: the XPS 15's thin chassis can't dissipate the 45W TDP under sustained load, leading to 100°C throttling and all-core clocks dropping to ~3.0GHz within 10 minutes of heavy rendering. There is no integrated NPU, meaning this device fails Microsoft's Copilot+ PC requirements entirely, with zero support for local LLM inference, Windows Studio Effects, or other 2026 AI workloads.

Memory bandwidth is a major bottleneck: DDR4-2666 delivers ~42GB/s bandwidth, 1/4 the ~170GB/s of modern LPDDR5X-8533 systems. The PCIe 3.0 SSD caps at ~3,500MB/s read speeds, half the ~7,000MB/s of modern Gen 4 drives.

Gaming Performance

The GTX 1650 4GB GDDR5 is a 2019 entry-level Turing GPU with no DLSS, AV1 encode, or modern feature support. At 1080p Medium settings, it delivers 30-45 FPS in 2026 AAA titles like *Cyberpunk 2077: Phantom Liberty* and *Starfield*, and cannot run 4K content at playable framerates (sub-20 FPS at 4K Low).

For context, AMD's 2026 Radeon 890M integrated graphics (found in Ryzen AI 300 laptops) outperforms the GTX 1650 by ~15% in most titles, making this discrete GPU entirely redundant for modern gaming. The Lenovo Legion 7 15IMH05 at the same $1399 price point includes an RTX 2070 Super, which delivers 2.5x the gaming performance of the XPS 15 7590.

The 4K panel is wasted for gaming: the GTX 1650 cannot drive 4K resolution at 60Hz in any modern title, and the 60Hz refresh rate makes fast-paced games feel sluggish.

Display Quality

The 15.6" 4K UHD InfinityEdge Touch panel is the only modern-adjacent feature of this device. It delivers ~500 nits peak brightness, 100% sRGB coverage, and 90% DCI-P3 gamut, making it suitable for color-accurate photo editing. The 282 PPI pixel density is sharp, with no visible pixelation even at close viewing distances.

However, it is a 60Hz IPS panel with no high refresh rate, which is a major downside in 2026: 120Hz is now the baseline for $1200+ laptops, and OLED panels dominate this price segment. The touch functionality works well with Dell's active pen (sold separately), but adds weight and reduces battery life. There is no mini-LED or local dimming, so black levels are typical IPS (~1000:1 contrast ratio).

Battery Life & Portability

The 97Wh battery is the maximum size allowed for airline travel, but the 14nm i7-9750H and 4K panel drain it rapidly. Light productivity use (web browsing, document editing) delivers ~6-7 hours of battery life, while heavy rendering or gaming cuts that to ~2 hours. For comparison, the renewed M1 Pro MacBook Pro 14 at $300 less delivers 17+ hours of light use.

Weight is 4.5 lbs (2.04kg) for the touch model, which is heavier than modern 15-inch ultrabooks: the 2026 MacBook Air 15 weighs 3.3 lbs, and the current XPS 15 9530 weighs 4.2 lbs. The 130W barrel charger is bulky, and while the laptop supports 65W charging via Thunderbolt 3, this disables full CPU/GPU performance.
