RTX 40-Series Laptops vs RTX 30-Series Gaming Laptops

We learn about the new RTX 40-Series laptops and compare the specs and features to the popular RTX 30-Series in our in-depth guide.


RTX 40-Series Laptops vs RTX 30-Series Gaming Laptops


NVIDIA has, of course, announced the release of their new RTX 40-Series GPUs for next-gen gaming laptops in 2023. This new line of graphics cards will indeed bring some exciting changes to the gaming laptop market, with a boat-load of extra VRAM and wider power limit ranges. In this article, we're going to take a closer look at the specs and features of the new RTX 40-Series, and compare them to the still very powerful (and popular) RTX 30-Series.

RTX 40-Series Graphics for Gaming Laptops

The RTX 40-Series includes five different graphics card options for gaming laptops: the RTX 4090, 4080, 4070, 4060, and 4050. One of the most notable changes in this new line of graphics cards is the increased VRAM. The lowest tier - that is still a great little spec for Esports and less demanding titles - GPU, the RTX 4050, now has 6GB of VRAM, while the RTX 4060 moves up to 8GB compared to the 6GB found in the previous RTX 3060, RTX 2060, and even GTX 1060 before that. This uplift essentially means the GPU is able to handle and display more intricate images and textures on the graphics chip, leading to improved performance.

Improved Power Efficiency

Another welcome change (for the gamers out there who don't like their legs toasted) in the RTX 40-Series is the wider power limit ranges. Previous generation mobile RTX 3070 GPU started at 80W minimum. The RTX 4070 can go as low as 35W, which is made possible due to the improved power efficiency that NVIDIA cannot stop talking about - for good reason. As anyone in a black and bright green t-shirt will tell you, NVIDIA's new Ada Lovelace architecture can compete against last gen 30 series with just 30% of the power.

Naturally, many have dismissed the screenshots and demos with a handful of salt, citing very little parity between last generation and new generation. For one thing, RTX 30-Series GPUs don't have DLSS 3, so it's hardly apples vs apples. The first benchmark news we saw from GeekBench and suggest bad drivers and low wattage might be the reason we haven't observed these lofty claims from Team Green just yet. Time is a great healer, however, and NVIDIA will be on the driver patch track right now righting this.

Gaming Performance

NVIDIA is showing some pretty big gains in gaming performance with the new RTX 40-Series as well. In a comparison graph, NVIDIA has demonstrated a 1.5x boost in games like Assassin’s Creed Valhalla or Red Dead Redemption 2, games that don’t currently implement DLSS 3. The massive 3x to 4x improvements are seen in games with Ray Tracing enabled. However, it's important to take these results with any remaining grains of salt and remain sceptical until we can get some trusty benchmark data.

RTX 4090: Less CUDA, But Still Powerful

NVIDIA also announced the flagship, scene-stealing RTX 4090 graphics for laptops, which may sound crazy, but it's important to note that the laptop version of the RTX 4090 has a significant 68% less CUDA cores compared to the desktop version. The fat has been trimmed for a mobile chassis, and this of course means that the laptop version will have less power and performance compared to the desktop version. To be fair, this is like trying to compact a Lamborghini Gallardo inside of a Ford Fiesta, so there's bound to be sacrifice. However, even with the reduced CUDA cores, the RTX 4090 for laptops will still be a powerful graphics card for gaming and other demanding tasks, and deserve their 40-Series nametag.

The RTX 4090 for laptops will support Ray Tracing and DLSS AI-based technologies, making them ideal for the usual fayre of photorealistic renderings, crisp animations, and real-time lighting and visualisation. The high performance and power efficiency of these graphics cards will also enable users to work with larger and more complex models, as well as perform simulations and other tasks with faster speeds.

Overall, the RTX 4090 for laptops represents a significant step forward in terms of performance and capabilities for professionals working in fields that require high-end graphics and computational power.

RTX 4090 Tech Specs

The GeForce RTX 4090 Mobile is built on the cutting-edge 4 nm process. It's based on the AD103 graphics processor, specifically in the GN21-X11 variant, which guarantees support for DirectX 12 Ultimate. This means that all the latest games will run smoothly on the chip. Additionally, the DirectX 12 Ultimate capability also guarantees support for hardware-raytracing, variable-rate shading, and more, in upcoming video games.

The AD103 graphics processor is a chunky chip with a die area of 379 mm² and 45,900 million transistors. It boasts 9728 shading units, 304 texture mapping units, 112 ROPs, 304 tensor cores, and 76 raytracing acceleration cores. These features help to improve the speed of machine learning applications. The chip also comes with 16 GB of GDDR6 memory, connected using a 256-bit memory interface. The GPU operates at a frequency of 1335 MHz, which can be boosted up to 1695 MHz, while the memory runs at 2000 MHz (16 Gbps effective).

The power draw of the device is rated at 150W maximum. The GeForce RTX 4090 Mobile does not have direct display connectivity, as it's not designed to be connected to monitors. Instead, it's intended for use in laptops and notebooks and will use the output of the host mobile device. It's connected to the rest of the system using a PCI-Express 4.0 x16 interface.

RTX 30-Series Comparisons

So, whilst the 40-Series might be hogging all the limelight right now, there are still excellent RTX 30-Series graphics cards for laptops.


RTX 4090 Laptop Benchmarks


The mobile RTX 3080 Ti is one of the finest graphics cards you can buy in a gaming laptop, with a significant amount of power for modern games, as you can see from the above NVIDIA chart. Of course, when compared with the RTX 4090, games like Cyberpunk 2077 run incredibly well on the new generation - but would you be happy with the performance like the below benchmarks?

Which should you buy? RTX 40-Series or RTX 30-Series?

If all goes according to plan with stock levels and distribution, then you might see some serious deals on the RTX 40-Series laptops - maybe enough to give you pause when looking at the above previous generation laptops. According to NVIDIA, the RTX 4080 and RTX 4090 laptops will be hovering around £1,999 in the UK, so this puts them in line with the top brass RTX 3070 Ti and RTX 3080 Ti (and may even be cheaper).

One thing is for sure. It is once again time to hold on to your hats: previous generation discounts are incoming.
