The video provides an in-depth comparison between a desktop PC and a gaming laptop, each equipped with Nvidia RTX 4090 graphics cards, tested across 25 games at various resolutions. Despite sharing the same name, the desktop RTX 4090 outperforms its laptop counterpart due to significantly higher CUDA cores, power limits, clock speeds, and memory specifications. The comparisons highlight the disparity in performance, with the desktop achieving higher frames per second (FPS) and better overall performance across GPU-intensive tasks and content creation benchmarks. Key games such as "Cyberpunk 2077," "Marvel’s Spider-Man Remastered," and "Call of Duty" show substantial performance gaps, especially at higher resolutions. The video also underscores the misleading nature of Nvidia’s naming conventions, as the laptop RTX 4090 more closely resembles a desktop RTX 4080 in specifications. Additionally, the discussion covers the cost differences, with the desktop offering better value and future upgrade potential while laptops provide portability. The video concludes that the choice between a desktop and laptop depends on personal needs, emphasizing that the performance benefit may not justify the added cost for most users. Future content comparisons for other GPUs are teased, encouraging viewers to subscribe for more detailed analyses.

In this segment of the video, the presenter compares a desktop PC and a gaming laptop, both equipped with Nvidia RTX 4090 graphics cards, across 25 games at 4K, 1440p, and 1080p resolutions. Despite sharing the same name, the desktop RTX 4090 vastly outperforms the laptop version due to having 68% more CUDA cores, three times the power limit, higher clock speeds, 50% more memory, and faster GDDR6X memory with a bigger memory bus. The laptop’s RTX 4090 is technically closer to a desktop RTX 4080 in specs. The segment stresses that Nvidia’s naming conventions might mislead consumers into expecting similar performance from both devices. For the tests, an MSI Titan GT77 gaming laptop with an Intel Core i9-13950HX processor was used to match the desktop setup as closely as possible, which included an Intel Core i9-13900K processor and 32GB of DDR5-5600 memory to minimize differences and focus on GPU performance. All games were tested at maximum settings to emphasize GPU capabilities.
00:03:00
In this part of the video, the discussion focuses on the RTX 4090 laptop GPU in the MSI Titan, which operates between 150 and 175 watts, highlighting it as optimal for a laptop GPU. It compares the performance and power efficiency of the RTX 4090 in laptops versus desktops, noting that laptops have lower power limits due to cooling constraints. Despite this, laptops are more power efficient in terms of FPS per watt. The desktop GPU achieves higher FPS due to greater power and higher clock speeds, and the desktop also benefits from 16 lanes of PCIe Gen 4 compared to the laptop’s 8 lanes. Game benchmarks for 25 games are introduced, showing performance differences at various resolutions. In “A Plague Tale Requiem,” the desktop outperforms the laptop significantly, especially at 4K. DLSS helps improve the laptop’s performance, but it still falls short of the desktop’s capabilities.
00:06:00
In this segment of the video, performance comparisons between a desktop and a laptop are detailed across various games at different resolutions and settings. The desktop generally outperforms the laptop, especially when both use frame generation technology. In “Cyberpunk 2077,” the desktop achieves a 56% higher frame rate at 4K ultra settings, while the laptop performs well at 1440p with 90 FPS but remains 49% slower. For “Dead Space,” the 1% low frame rates were significantly worse on the laptop, negatively impacting performance at lower resolutions. With “The Witcher 3” next-gen update, the desktop maintains a 61% lead even when using ray tracing and FSR. Microsoft’s Flight Simulator showed the smallest performance gap, with the desktop being 29-53% faster depending on the resolution, and both systems benefiting from frame generation and DLSS upscaling features.
00:09:00
In this part of the video, the performance differences between a laptop and desktop 4090 GPU are examined across various games at different resolutions. “Marvel’s Spider-Man Remastered” showcased minimal FPS difference between 1080p and 1440p due to its CPU-heavy nature. At 1440p, the desktop was 25% faster than the laptop, but at 4K, the desktop exhibited a 56% higher average FPS with significantly smoother performance.
For “Call of Duty,” tested using the game’s benchmark, the desktop was 40% faster at 1440p and 52% faster at 4K compared to the laptop. In “Apex Legends,” frame caps masked the desktop’s capability, making it appear only marginally faster at lower resolutions, but at 4K, the desktop performance was more than double that of the laptop.
Similar trends were noted in other titles like “Control” and “Fortnite,” with desktops hitting frame caps or vastly outperforming laptops at higher resolutions. The video skips through the results of the remaining games but emphasizes that a broader range of data from 25 games provides more accurate performance conclusions.
00:12:00
In this part of the video, various benchmarks are compared between the RTX 4090 desktop GPU and the RTX 4090 laptop GPU. For 1080p gaming, the desktop GPU was 37% faster, but higher resolutions show more significant differences. At 1440p, the desktop was 49% faster, and at 4K, the desktop GPU was almost 67% faster, showcasing a notable performance gap. The video highlights that the desktop version of the GPU performs much better in GPU-heavy games, sometimes nearly twice as fast, with substantial improvements in CPU-heavy games as well. In content creation benchmarks like Blender and DaVinci Resolve, the desktop card again outperforms with 40-62% higher scores. Despite sharing the same name, the desktop 4090 model delivers significantly better performance than its laptop counterpart across various tests.
00:15:00
In this part of the video, the presenter discusses the performance and cost differences between the desktop and laptop versions of the Nvidia RTX 4090 GPU. The desktop performs better in every workload due to higher CPU power limits, and it is also significantly cheaper, costing around $4000 compared to the laptop’s $5300 price tag. The video highlights that while desktops offer better cost per frame and easier future upgrades, laptops provide portability and convenience with built-in components. Ultimately, the choice between them depends on personal needs like portability versus performance and space constraints. The presenter personally prefers a powerful desktop for home use and a portable laptop for travel.
00:18:00
In this part of the video, the speaker advises against spending extra money on the RTX 4090 unless one needs the utmost performance in either desktop or laptop form factors. They highlight that most users won’t find the performance difference justifies the additional cost. The segment also underlines that laptop and desktop versions of the RTX 4090 perform differently despite sharing the same name, which can be misleading. The speaker invites viewers to check out comparisons of other laptop and desktop GPUs in upcoming videos, particularly the 30 series and future comparisons for RTX 4080, 4070, 4060, and 4050, encouraging them to subscribe for more content.
