Do You Need 32GB of VRAM? The RTX 5090 Explained

When NVIDIA unveiled the GeForce RTX 5000 series at CES 2025, the headline feature was the massive 32GB of VRAM in the RTX 5090. This is a significant jump from its predecessor, the RTX 4090, which featured 24GB. Naturally, this has sparked a lot of debate in the gaming and tech communities: Is 32GB of VRAM really necessary for today’s games, or is it more of a future-proofing measure for tomorrow’s titles?

Let’s break down the advantages and potential drawbacks of this monster of a GPU and assess whether 32GB of VRAM is truly essential for current gaming or just a step into the future.

What Does VRAM Do, and Why Is It So Important?

Before diving into whether 32GB of VRAM is necessary, let’s first explore the role of VRAM (Video RAM) in gaming. VRAM is crucial because it stores graphical data, like textures and frame buffers, which the GPU uses to render high-quality visuals. The more VRAM a GPU has, the more data it can handle at once, ensuring smoother gameplay, especially at higher resolutions, and when using advanced graphical effects like ray tracing.

In short, VRAM affects how well your GPU can handle the graphical demands of modern games, particularly at higher resolutions (4K and beyond), and with settings like ultra textures, ray tracing, and other demanding visual features enabled.

The Perks of 32GB VRAM

The RTX 5090’s 32GB of GDDR7 VRAM running at 28 Gbps on a 512-bit interface means it can handle nearly 1.8 TB/s of bandwidth—double the capacity of the RTX 4090. While that’s a huge leap forward, what does it mean for performance?

  1. Future-Proofing for 8K Gaming One of the key benefits of 32GB VRAM is its ability to handle 8K gaming. As displays push toward higher resolutions, the need for more VRAM grows exponentially. 8K games, with their massive textures and intricate environments, can overwhelm a GPU with lower memory capacities. The RTX 5090’s generous VRAM ensures you’ll be prepared for this next-gen gaming experience, with enough headroom to handle ultra-detailed textures and effects at 8K.

  2. Next-Level Performance in VR and Simulations VR and simulation-based applications are some of the most graphically intense workloads out there. From intricate flight simulators to VR games with complex environments, VRAM plays a critical role in maintaining smooth and immersive experiences. The RTX 5090’s 32GB VRAM gives it the power to handle these demanding applications with ease, ensuring a lag-free and lifelike experience in virtual environments.

  3. Enhanced Ray Tracing and AI Features With the new Blackwell architecture, improved Ray Tracing (RT) cores, and revamped Tensor cores, the RTX 5090’s 32GB VRAM ensures that it can fully leverage the advancements in ray tracing and AI-driven features like DLSS 4. Ray tracing, which simulates the behavior of light, requires vast amounts of memory for real-time calculations of lighting, shadows, and reflections. With 32GB of VRAM, the RTX 5090 is more than capable of handling these effects without sacrificing frame rate or visual quality.

  4. Creative Workloads and Multitasking For creative professionals working with 3D rendering, video editing, or AI-based tasks, 32GB VRAM offers ample space for multitasking. Whether you're running demanding software like Blender or Premiere Pro, or working with large textures and assets, the additional memory allows you to work more efficiently, without worrying about memory bottlenecks or slowdowns.

Is 32GB of VRAM Really Necessary for Current Games?

At this point, the big question is whether you actually need 32GB of VRAM for current gaming. Today, most high-end games, even those with demanding graphical features like Cyberpunk 2077 and Red Dead Redemption 2, perform well with 16GB or 12GB of VRAM—particularly at 4K resolution.

While the RTX 5090’s 32GB of VRAM certainly offers some performance headroom, it’s not likely to offer a noticeable difference in frame rates for most gamers at present. Games released today don’t yet push VRAM limits to the extent that 32GB is necessary. So, what gives?

The Road Ahead: Tomorrow’s Demands

RTX 5090
The real benefit of 32GB VRAM lies in what’s coming next. As we move toward even more demanding games, especially those targeting 8K resolution, higher fidelity ray tracing, and AI-enhanced content, the need for more VRAM will become more apparent. Titles that fully embrace these technologies will start demanding more from GPUs, and the 32GB of VRAM in the RTX 5090 will ensure that it’s ready for whatever future games throw at it.

In addition, the growing trend of large open-world games, detailed simulations, and AI-generated environments will increase the VRAM requirements. As developers start to create even more immersive and visually stunning worlds, having more VRAM will provide the breathing room to render complex scenes without lag or stutter.

Potential Drawbacks: Is 32GB VRAM Overkill?

While the RTX 5090’s 32GB VRAM sounds impressive, it’s not without potential drawbacks:

  1. Price Tag The inclusion of 32GB of VRAM is likely to push the price of the RTX 5090 into premium territory. For most gamers, especially those focused on 1440p or 4K gaming, the RTX 5090’s 32GB VRAM may be an expensive luxury. The additional memory might not justify the cost, especially if you’re not planning to play games at 8K resolution or make use of the most demanding graphical settings.

  2. Power Consumption The RTX 5090 consumes a significant amount of power—around 575W—meaning you’ll need a powerful PSU to support it. The additional VRAM could contribute to the overall power draw, potentially requiring enhanced cooling solutions to keep temperatures under control. For users with older or more compact builds, the RTX 5090’s power needs might present a challenge.

  3. Diminishing Returns For the average gamer, especially those playing at 1440p or 4K, 32GB of VRAM might not offer a tangible performance boost over 24GB or even 16GB. While it’s always nice to have more headroom, VRAM usage in today’s titles is still relatively modest. Unless you’re gaming at 8K or engaging in highly demanding professional workloads, the RTX 5090’s 32GB VRAM could be more than you actually need.

Conclusion: Is 32GB VRAM Worth It?

The inclusion of 32GB VRAM in the RTX 5090 is undoubtedly a bold move by NVIDIA. It provides the GPU with the power to handle demanding tasks today and future-proofs it for the next decade of gaming. For those pushing the limits of gaming with 8K, ray tracing, and AI-powered graphics, the RTX 5090’s VRAM capacity is more than just a luxury—it’s a necessity.

However, for most gamers, especially those not yet embracing 8K gaming or heavy modding, 32GB VRAM might be overkill. The RTX 4090 with 24GB of VRAM remains more than capable for today’s games, and unless you’re looking to future-proof your rig for years to come, you might not see much benefit from the extra memory right now.

In the end, the RTX 5090 offers power and performance for those who need it, but whether it’s worth the investment depends on your specific gaming and creative needs. Do you need 32GB of VRAM? If you’re preparing for the next generation of gaming, then yes. For now? Not necessarily.
