Nvidia RTX 5000 Ada Generation Laptop GPU vs Nvidia GeForce RTX 5080 Laptop

Nvidia RTX 5000 Ada Generation Laptop GPU

The Nvidia RTX 5000 Ada Generation, not to be confused with the A5000, P5000 and the RTX 5000 Turing Generation, is a super-powerful professional graphics card for use in laptops that sports 9,728 CUDA cores and 16 GB of ECC GDDR6 VRAM. Brought into existence in 2023, this graphics adapter leverages TSMC's 5 nm process and Nvidia's Ada Lovelace architecture to achieve great performance combined with reasonable power consumption. The Nvidia-recommended TGP range for the card is very wide at 80 W to 175 W leading to bizarre performance differences between different systems powered by what is supposed to be the same product.

Hardware-wise, the RTX 5000 is a GeForce RTX 4090 Laptop in disguise. Consequently, both make use of the AD103 chip and have little difficulty running triple-A games at UHD 2160p.

Quadro series graphics cards ship with much different BIOS and drivers than GeForce cards and are targeted at professional users rather than gamers. Commercial product design, large-scale calculations, simulation, data mining, 24 x 7 operation - if any of this sounds familiar, then a Quadro card will make you happy.

Architecture and Features

Ada Lovelace brings a range of improvements over older graphics cards utilizing the outgoing Ampere architecture. It's not just a better manufacturing process and a higher number of CUDA cores that we have here (up to 16,384 versus 10,752); under-the-hood refinements are plentiful, including an immensely larger L2 cache and an optimized ray tracing routine (a different way to determine what is transparent and what isn't is used) and other changes. Naturally, these graphics cards can both encode and decode some of the most widely used video codecs, AVC, HEVC and AV1 included; they also support a host of proprietary Nvidia technologies, including Optimus and DLSS 3, and they can certainly be used for various AI tasks.

The RTX 5000 features 76 RT cores of the 3rd generation, 304 Tensor cores of the 4th generation and 9,728 CUDA cores, making it a lot faster than the RTX 4000 Ada Generation. Elsewhere, the graphics card comes with 16 GB of 256-bit wide ECC GDDR6 memory for an impressive throughput of ~576 GB/s. Error correction can be turned off if desired. The fact that error correction is present here proves that the RTX 5000 is indeed targeted at professional users.

Just like Ampere-based cards, the RTX 5000 makes use of the PCI-Express 4 protocol. 8K SUHD monitors are supported, however DP 1.4a video outputs can potentially prove to be a bottleneck down the line.

Performance

The average RTX 5000 Ada Generation in our extensive database is noticeably inferior to the GeForce RTX 4080 in some tests but is totally comparable to the GeForce RTX 4090 in other ones, such as the Geekbench 6.2 GPU Vulkan test.

Nvidia's marketing materials mention "up to 42.6 TFLOPS" of performance which is very impressive. The RTX 4000 Ada Generation delivers up to 33.5 TFLOPS, for reference, while the RTX 500 Ada is only good for 9 TFLOPS.

Your mileage may vary depending on how competent the cooling solution of your laptop is and how high the TGP power target of the RTX 5000 is. One other thing worth mentioning is that enabling error correction appears to reduce the amount of video memory that is available to applications and games by up to a gigabyte.

Power consumption

Nvidia no longer divides its laptop graphics cards into Max-Q and non-max-Q models. Instead, laptop makers are free to set the TGP according to their needs, and the range can sometimes be shockingly wide. This is the case with the RTX 5000 Ada, as the lowest value recommended for it sits at just 80 W while the highest is more than two times higher at 175 W (this most likely includes Dynamic Boost). The slowest system built around an RTX 5000 Ada can easily be 60% slower than the fastest one. This is the kind of delta that we've already seen on consumer-grade laptops featuring the latest GeForce RTX cards.

Last but not the least, the improved 5 nm process (TSMC 4N) the RTX 5000 is built with makes for very decent energy efficiency, as of mid 2023.

Nvidia GeForce RTX 5080 Laptop

The Nvidia GeForce RTX 5080 Laptop is a high-end notebook graphics card that was presented at CES 2025 and went on sale in April 2025. 

Architecture

The GeForce RTX 5080 Mobile utilizes the Blackwell GB203 chip and employs 8,192 of the chip's 10,752 cores. Compared to the similar named desktop chips, it therefore is nearer to the desktop RTX 5070 (6.144 cores) than the similar named desktop RTX 5080 (10.752 cores). The memory bus is however like the desktop RTX 5080 a 256 Bit bus for 16 GB GDDR7.

As a novelty, Blackwell offers support for Multi-Frame Generation (MFG) with DLSS4, thanks to the 5th generation of Tensor cores.

Performance

The average theoretical performance of the laptop RTX 5080 is similar to the desktop RTX 5070 and the older RTX 4090 Laptop GPU (Time Spy GPU). In games (e.g. Doom: The dark ages), the performance is also on par with the old RTX 4090 Laptop GPU, although the RTX 5080 supports the already mentioned MFG option for impressive frame rates. Still the latency is the same, so you should start from at least 60 fps without frame generation.

Power consumption

The GB203 is manufactured at TSMC using the 4N FinFET process (custom 4NP 5nm). The maximum TGP of the card can reach 150 watts (125 watts + 25 watts Dynamic Boost).
