When it comes to professional gaming, one brand dominates the market: NVIDIA. The RTX GPUs have a reputation for being the best, mainly because the Ray Tracing Texture Extreme technology is unique and presents visuals as realistically as possible.
It’s fair to say that the GPUs by NVIDIA are a game changer, but there’s always one better than the other. Here, the subjects of our debate are the RTX 5070 and 4070 Gaming laptop GPUs. Not only are these two picked from different series (one predecessor and the other successor), but also both are considered beyond decent for gaming.
Naturally, one would assume that the upgraded version would be better, but the tech world is full of plot twists and loopholes. So let’s decide which one is better with this concise and comprehensive comparison of the two viral gaming GPUs, the Nvidia RTX 4070 or the Nvidia RTX 5070.
NVIDIA RTX 5070 – Overview
The RTX 5000 is a series of graphics cards designed for a strong visual output. As per the function of a proficient graphics processing unit, this die skillfully renders the textures while maintaining the frame rates, all in a single smooth flow. The complete range of this series was launched at the end of January 2025.
The Ray Tracing Texture Extreme technology of this GPU range adds diversity in terms of visual effects, from reflections to soft shadows. This ensures that the illustrations of the games look as realistic as possible to the human eye. But the wonders of 5070 don’t just end there. The Blackwell architecture acts as a moderator for the large language models.
NVIDIA RTX 4070 – Overview
Released in September 2020, the RTX 4000 was considered a mastermind chip back in its day. Renowned for the power it provides while decoding graphic-intensive tasks, this series got all the hype then. Not only did it create greater frames than regular cards, but it also emphasized the quality of the illustrated output. All this was handled under the DLSS 3, which was powered by AI.
At the time of its launch, the 4070 had multiple USPs, and among them was its speed. The responsiveness of this GPU provided gamers with the ultimate competitive edge. With accelerated reflexes and unmatched 3D rendering, the 4070 proved to be an iconic component of gaming laptops.

Architecture
While evolving from the 4070 to the 5070, NVIDIA was transitioning from the Ada Lovelace to the Blackwell architecture. Undoubtedly, the Lovelace design is the OG as it brought the concept of advanced real-time ray tracing to life. It partnered with the DLSS 3.0, which in turn utilizes AI for cinematic visuals with an impact on simulations.
Blackwell, on the other hand, swapped the components for advanced ones. For example, instead of third-generation tensor cores, it incorporated fourth-generation. It also focused on reduced memory requirements for speedy computations. In short, the Blackwell architecture is engineered to handle hectic workloads.
Performance
The 5070 excels in terms of graphics performance, like other cards in the series. While the 4070 offers a lightning of 260fps and reflection of 268fps, the 5070 scores 318fps for lightning and 303fps for reflection handling. Not only that, but the N-body simulation (Gravity) of the 4070 is 235fps compared to the 419fps of the 5070.
Additionally, the texture detail of 5070 is much better than its predecessor, with the average parallax standing at 310fps. Another outstanding feature of the latter counterpart is its GDDR7 memory bandwidth, which beats the GDDR6, thanks to its high density and compact memory module.
AI Acceleration
To know how good the AI acceleration of a graphics die is, you should look into its TOPS, tensor cores, and RT cores. These three metrics measure the amount of workload one chip can handle in a second. Hence, the higher the metrics, the better most of the time. Now, the 4070 features 522 TOPs less than the 5070. This means the AI consumes and processes the tasks slowly.
Similarly, the CUDA cores are 512 more in the later model, contributing to a slower training and conclusion-reaching pace in the 4070. As for the RT cores, you guessed it right, there are two cores in the previous counterpart, which means the BVH management and complex computations are a tad bit time-consuming.
Power Consumption
A GPU with substantially low energy consumption is not only beneficial for the hardware of the device plus chip, but it is also cost-saving in other ways. For starters, it saves electricity; secondly, it avoids the cost of maintenance of the laptops as it slows down less. The 5070 charges an average of 250W of electricity.
On the contrary, the 4070 consumes around 200W per session of usage. With the comparatively low power consumption rate of the 4070, the perks include high and consistent clock speeds for efficient multitasking. Moreover, it ensures enhanced computing capabilities for gamers and video editors, which is a huge plus point.
Design & Price
The 5070 graphic die, also known as the GB205, measures 263 sqmm. While the tiny card is applauded for its compact build, there’s an obvious drawback of the low transistor count of 31.1 billion. As for the 4070, it measures 294 sqmm, with a transistor count capacity of 35.8 billion, showing that the 4070 offers increased computing power over time. Lastly, in terms of price, there isn’t a considerable difference between the two, as the 5070 costs around $600, whereas the 4070 costs $550.
Final Verdict – 5070 or 4070?
After critically evaluating the two gaming laptop graphics cards, we have come to the obvious conclusion that the 5070 is a hundred percent worth the upgrade. The switch from Ada Lovelace to Blackwell has made the upgrade possible, mainly because it is the architecture that brings in a variety of innovative components.
The AI performance is also applaudable in the 5070, which in turn contributes to the graphics representation and processing. Despite the humongous updates in the chip, the price factor falls under the affordable tag, which makes it easily accessible, so why not switch to the superior option?
