RAM-tastic Gaming: AMD’s New Tech Lets Laptops Borrow Memory for Better Performance

AMD’s New Variable Graphics Memory: A Game Changer for Laptops?

The world of gaming laptops is constantly evolving, with manufacturers pushing the boundaries of performance and portability. One key aspect of this evolution is the management of system memory – the shared pool of RAM that powers both the CPU and GPU. While traditional laptops allocate a fixed amount of memory to the GPU, AMD’s new Variable Graphics Memory (VGM) technology allows users to dynamically adjust how much RAM is dedicated to graphics processing, potentially boosting performance significantly.

A Quick Look at VGM

VGM is a game-changing feature that allows users to allocate up to 75% of their system memory as dedicated video RAM (VRAM). This is done through a simple interface within AMD’s Adrenalin desktop app, eliminating the need for complex BIOS modifications. This dynamic allocation enables laptops to handle graphics-intensive games and applications with greater efficiency, potentially pushing performance to new levels.

How Much VRAM Can Be Allocated?

The amount of system memory that can be diverted depends on the total system RAM. AMD explains that a 32GB laptop with 512MB of dedicated VRAM will see the "medium" setting convert its memory into a 24GB system with 8GB of dedicated VRAM. This can mean a substantial increase in dedicated graphics memory, potentially leading to major performance gains.

Real-World Performance: A Mixed Bag

While the concept of VGM is enticing, its real-world performance is not a universal magic bullet. While some games, like Alan Wake II, which demand significant VRAM, will benefit greatly, others might see smaller gains or even slight performance decreases.

Early Testing Insights:

Initial testing with the Asus Zenbook S 16, a Strix Point laptop equipped with VGM, by reviewer Joanna Nelius revealed mixed results. While the game Control achieved a noticeable performance improvement, jumping from 54fps to 65fps with 8GB of VRAM, other titles saw less impactful changes or even slight framerate drops. This suggests that VGM’s effectiveness varies depending on the individual game’s resource requirements and optimization.

The Potential for Frame Rate Boosting:

AMD claims that VGM could potentially unlock significant frame rate improvements, particularly for games already running at a reasonable baseline. The company points to their FidelityFX Super Resolution (FSR) upscaling technology, suggesting that laptops previously capable of 39fps in Horizon Zero Dawn could achieve a smooth 66fps on a 2880 x 1800 screen with VGM and FSR combined.

AMD’s FSR 2.0: Enhancing Upscaling Capabilities

FSR 2.0, AMD’s latest upscaling technology, adds temporal injection, a frame generation technique that aims to generate smoother and more visually appealing frames. This technology works particularly well in conjunction with VGM, allowing for a significant performance boost by freeing up VRAM for the upscaling process. AMD has stated that FSR 2.0 can deliver substantial frame rate boosts, especially for games with an initial frame rate of 50fps or higher. However, the company has not yet disclosed whether FSR 2.0 delivers a higher frame rate than the original version of FSR.

Beyond VGM: AMD RX 7800M

Beyond VGM, AMD recently announced the RX 7800M, a powerful new mobile GPU intended for high-performance gaming laptops. This 180W chip boasts 12GB of dedicated VRAM, positioning itself as a mid-tier offering in the mobile GPU landscape. Tom’s Hardware has described it as "essentially a stripped-down RX 7800 XT," highlighting its potential for delivering a powerful and engaging gaming experience.

Filling a Gap in AMD’s Lineup:

The RX 7800M effectively fills the gap between AMD’s flagship RX 7900M and the RX 7600M XT, providing a compelling option for users seeking a powerful mobile GPU without the high cost of the flagship model. This expansion of AMD’s mobile GPU lineup reinforces their commitment to delivering powerful and versatile solutions for gamers and content creators alike.

The Future of Gaming Laptops:

VGM has the potential to significantly impact the future of gaming laptops, providing a much-needed boost to performance for those who crave the best gaming experience. However, the technology’s effectiveness varies depending on the specific game and system configuration. As more games leverage VRAM-intensive features, AMD’s technology could prove to be a significant differentiator for its mobile CPUs and GPUs.

The Verdict:

So, is AMD’s Variable Graphics Memory a game changer for laptops? While it’s still early in the technology’s lifecycle, the initial signs are promising. VGM can provide significant performance gains for certain games, allowing users to push their laptop’s capabilities further. However, it’s important to remember that VGM is not a universal solution and its effectiveness will vary based on individual game requirements and system configurations.

As VGM continues to evolve and AMD continues to expand its mobile GPU offerings, the future of gaming laptops looks exciting and full of potential for powerful performance and immersive experiences.
