Is 8GB of VRAM Enough for Gaming Laptops? A Detailed Breakdown

With advancements in gaming technology, one question persists for gamers shopping for laptops: is 8GB of VRAM enough, or should you invest in a model with 12GB or even 16GB? This article dives into an in-depth comparison between two almost identical gaming laptops, differing only in VRAM—8GB versus 16GB—and tests their performance at various resolutions to determine if upgrading VRAM truly makes a difference in gaming.

Understanding VRAM and Its Role in Gaming

VRAM (Video RAM) is a special type of memory dedicated to graphics processing. It stores textures, shadows, and other data the GPU needs quick access to for rendering images. When VRAM isn’t sufficient, the system uses slower system memory instead, which can lead to reduced performance, lower quality textures, or both—ultimately impacting the gaming experience. VRAM demand varies based on resolution, graphics settings, and whether advanced features like ray tracing are enabled.

VRAM in the Latest Laptop GPUs

With NVIDIA’s latest RTX 40 series GPUs, VRAM options are limited for laptops. The RTX 4070 comes with 8GB of VRAM, while upgrading to the RTX 4080 offers 12GB, and the top-tier RTX 4090 provides 16GB. However, in the previous RTX 30 series, models like the RTX 3080 were available with either 8GB or 16GB, making it possible to test directly whether VRAM capacity alone significantly affects gaming performance.

Key Tests and Findings Across Resolutions

1. 1080p Performance

• Alan Wake 2: At 1080p with high settings, both 8GB and 16GB laptops performed similarly, achieving about 30 FPS. The VRAM limit was only slightly surpassed, showing minimal impact on frame rates.
• Cyberpunk 2077: VRAM use exceeded 8GB only at ultra settings with ray tracing. However, frame generation combined with FSR upscaling helped manage the demand without causing major performance dips, meaning 8GB VRAM was sufficient for most settings at this resolution.

2. 1440p Performance

• Alan Wake 2 saw more VRAM usage at 1440p, with both medium and high settings demanding more than 8GB. While the 16GB model had a smoother experience, the difference was primarily noticeable in the 1% lows—indicating less stuttering on the 16GB VRAM setup.
• Hogwarts Legacy also utilized over 8GB at ultra settings, and the 16GB laptop had a slight edge in both average FPS and 1% lows, though the difference wasn’t game-changing.

3. 4K Performance

• At 4K, many games like Cyberpunk 2077 and Starfield required more than 8GB of VRAM at higher settings, but actual FPS improvements with 16GB were minimal, as the laptop GPUs themselves lacked the power to render games smoothly at such high resolutions without upscaling.
• Texture Quality: In games like Hogwarts Legacy, limited VRAM on the 8GB laptop could lead to texture pop-ins, though recent updates appear to have mitigated this issue to some extent.

The Impact of Frame Generation on VRAM Usage

While RTX 40 series GPUs support NVIDIA’s DLSS 3 frame generation, which improves FPS, it also increases VRAM usage. Testing reveals that enabling this feature demands additional VRAM, which could push 8GB cards to their limit, especially at higher resolutions. This makes the case for more VRAM if you’re planning to use these features extensively.

Is 8GB VRAM Enough?

While 8GB is sufficient for most gaming laptops, there are some exceptions:

• Resource-Intensive Games at High Settings: Games like Alan Wake 2, Cyberpunk 2077, and Hogwarts Legacy benefit from 16GB VRAM, especially at 1440p or higher with ray tracing enabled.
• Future-Proofing: As games evolve, VRAM demands are likely to increase, especially if textures and rendering quality improve in newer titles.

However, for the current generation, most laptops lack the GPU power to fully utilize more than 8GB VRAM. If you’re primarily gaming at 1080p or 1440p without maxing out ray tracing, 8GB should suffice for now. NVIDIA may need to increase VRAM in future models like the expected RTX 5070, as higher resolutions and advanced graphics settings become more mainstream.

Conclusion: 8GB vs. 16GB VRAM—Which is Right for You?

If you’re looking to play the latest games on high settings and want a smoother experience at higher resolutions, opting for a 16GB VRAM laptop can offer slight but noticeable improvements, particularly in 1% lows and stability. For gamers focused on 1080p, however, 8GB VRAM is still a viable choice. With NVIDIA’s potential for more VRAM in future GPUs, a shift towards 12GB as the baseline could enhance laptop performance and keep pace with game development trends.
