By the end, you’ll have a clear understanding of each GPU’s strengths and weaknesses, empowering you to make an informed decision when choosing your next gaming laptop.
Under the Hood: Architecture and Specifications
The AMD Radeon RX seventy-nine hundred M is built upon AMD’s cutting-edge RDNA three architecture. This architecture introduces a chiplet design and promises significant improvements in performance per watt compared to previous generations. The seventy-nine hundred M is fabricated on a leading-edge process node (typically a variant of TSMC’s five-nanometer process), allowing for a high transistor density and improved efficiency.
Key specifications of the AMD Radeon RX seventy-nine hundred M include a substantial number of compute units and stream processors, a high boost clock speed, a generous amount of GDDR six memory, and a wide memory bus width. The total graphics power (TGP) is a crucial factor, indicating the maximum power the GPU can draw, which directly impacts its performance potential. The higher the TGP, the more headroom the GPU has to boost its clock speeds and deliver higher frame rates. Important improvements related to ray tracing and artificial intelligence acceleration have been made in this new architecture.
The NVIDIA GeForce RTX forty-eighty Laptop, on the other hand, is based on NVIDIA’s Ada Lovelace architecture. Ada Lovelace brings significant advancements in ray tracing, artificial intelligence-powered features, and overall performance. This GPU is manufactured using a custom process node (often a variant of TSMC’s four-nanometer process), which allows for a high level of integration and efficiency.
The RTX forty-eighty Laptop boasts a high number of CUDA cores, a high boost clock speed, and GDDR six memory. A critical aspect of NVIDIA’s laptop GPUs is the configurable TGP. Laptop manufacturers can choose from a range of TGP values for the RTX forty-eighty Laptop, which can significantly impact its performance. A higher TGP allows the GPU to boost higher and maintain those clocks for longer. Besides that there’s also improved Ray Tracing performance, and specialized hardware for AV one encoding.

Gaming Prowess: Performance Benchmarks
To assess the gaming performance of these GPUs, rigorous testing across a range of titles is essential. This includes AAA games with demanding graphics, as well as eSports titles where high frame rates are crucial. Tests should be conducted at various resolutions, including ten-eighty p, fourteen-forty p, and potentially four K (depending on the GPU’s capabilities).
Benchmarking Methodology
Games were tested at their highest settings on each card to see how the performance held up. Each game was given time to warm up the card before benchmarking them. The games were tested multiple times to reach consistent results.
Ten-Eighty p Gaming
At ten-eighty p, both GPUs are expected to deliver exceptional frame rates in most games. The differences between the two may be less pronounced at this resolution, as the CPU might become a limiting factor in some cases. However, even at ten-eighty p, you can expect that both cards will deliver above sixty frames per second on the most demanding titles.
Fourteen-forty p Gaming
Fourteen-forty p is often considered the sweet spot for gaming, offering a balance between visual fidelity and performance. At this resolution, the performance gap between the AMD Radeon RX seventy-nine hundred M and the NVIDIA GeForce RTX forty-eighty Laptop may become more apparent. Some games tend to favor AMD architectures, while others are optimized for NVIDIA hardware.
Four K Gaming
While both GPUs are capable of gaming at four K, this resolution presents a significant challenge. Frame rates may drop below sixty frames per second in some demanding titles, even with high-end hardware. In those cases you will either have to lower settings, or enable a supersampling method.
Ray Tracing Performance
Ray tracing is a demanding rendering technique that simulates the behavior of light to create more realistic and immersive visuals. The RTX forty-eighty Laptop, with its dedicated ray tracing cores, is generally expected to perform better in ray tracing-intensive games. However, AMD has made significant strides in ray tracing performance with their RDNA three architecture, and the seventy-nine hundred M may offer competitive performance in some titles, especially when paired with FidelityFX Super Resolution (FSR). NVIDIA cards have the added benefit of DLSS frame generation though.
Beyond Gaming: Performance in Other Applications
The AMD Radeon RX seventy-nine hundred M and the NVIDIA GeForce RTX forty-eighty Laptop are not just for gaming. They can also be used for a variety of other tasks, such as content creation, video editing, and three D rendering.
Content Creation
In applications like Blender, DaVinci Resolve, and Adobe Premiere Pro, the NVIDIA GeForce RTX forty-eighty Laptop often holds an advantage due to its CUDA cores and optimized drivers. However, the AMD Radeon RX seventy-nine hundred M can still deliver solid performance in these applications, especially in tasks that are more reliant on raw processing power. In some applications, one brand of GPU will significantly outperform the other depending on how the software is coded and optimized.
AI and Machine Learning
While not typically the primary use case for these GPUs, they can also be used for AI and machine learning tasks. NVIDIA’s CUDA architecture and software ecosystem have historically given it an edge in this area, but AMD is making progress with its ROCm platform.
Power and Heat: Consumption and Thermals
Power consumption and thermal management are critical considerations for laptop GPUs. The AMD Radeon RX seventy-nine hundred M and the NVIDIA GeForce RTX forty-eighty Laptop are both high-performance GPUs that can draw significant power.
