Synthetic Benchmark Results
Our first round of testing employed 3DMark Fire Strike, traditionally a staple for evaluating the raw rendering power of GPUs despite the decline of DirectX 11. Its tried and tested nature serves as a foundation for comparing older graphics cards.
Subsequently, we proceeded to 3DMark Time Spy, leveraging DirectX 12’s capabilities. This benchmark typically yields more substantial results for newer GPUs, as they incorporate advanced rendering technologies. Nevertheless, virtually any GPU launched post-2018 should perform commendably here.
Ray tracing technology highlights the prowess of both Blackwell and Ada Lovelace architectures, with enhanced RT cores yielding remarkable improvements. In particular, the 50 series showcases nearly double the performance in 3DMark’s ray tracing tests, overshadowing the previous champion, the RTX 4080 laptop GPU.
In the 3DMark Port Royal benchmark—designed to assess real-time ray tracing capabilities—the RTX 5080 nearly equals the RTX 4090 in terms of overall performance.
3DMark Speed Way merges DirectX 12 Ultimate standards with ray tracing, and in this test, the RTX 5080 outpaces the Radeon RX 7900 XTX by a significant margin while retailing at a comparable price point.
Furthermore, the RTX 50 series takes the lead in DLSS performance, enhanced by the implementation of multi-frame generation, which can substantially multiply framerates by anywhere from 2x to 4x. This breakthrough is truly evident in 3DMark’s DLSS feature tests.
Despite being one of the most potent graphics cards available, the RTX 5080’s performance improvements over its predecessor remain modest. It still lags behind the 4090 in terms of pure rasterization. Consequently, this graphics card offers the most appeal to users upgrading from significantly older GPUs, such as the 2080 Super or the 3080.
Real-World Gaming Performance
Testing the RTX 5080 across various game titles, we found that it effectively handled modern games without noticeable performance drawbacks, even with ray tracing enabled. In demanding scenarios like *Cyberpunk 2077* and *Marvel’s Spider-Man 2*, it managed to sustain framerates between 150-200 FPS with DLSS 4 and frame generation activated.
Frame generation can be configured in three modes: 2x, 3x, and 4x. For *Cyberpunk 2077*, we meticulously examined each setting, revealing performance gains of 293%, 409%, and an astonishing 525%, leading to an average framerate of 163 FPS.
The AI optimizations integrated into Nvidia’s lineup enhance the gaming experience, enabling highly fluid gameplay even under intensive workloads.

The RTX 5080 commands a robust 360W power budget, necessitating a high-capacity power supply with PCIe 5.0/5.1 support to ensure stability. The Founder’s Edition’s compact design does lead to increased temperatures during high loads.
Under intense testing with Furmark 2, the GPU reached a maximum temperature of 71.5°C, with a controlled ambient temperature of 21°C via air conditioning. In gameplay scenarios, particularly in *Cyberpunk 2077* without DLSS, the highest recorded temperature was a commendable 65°C—manageable for a dual-slot graphics card.
During power testing, the RTX 5080 exhibited the ability to rapidly reach its peak rating under demanding conditions. In extreme scenarios within *Cyberpunk 2077*, it drew 323W. Broadly, the average power consumption settled around 235W.
In synthetic tests like Furmark 2, the GPU consistently consumed 360W, occasionally peaking at 372W. Notably, spikes of this nature were not observed during gaming sessions, but they do emphasize the necessity for ample power headroom—an optimal choice would be no less than a 750W power supply for builds incorporating the RTX 5080.
AI Capabilities and Their Current Limitations
A key selling point of the RTX 50 series is its AI capabilities. As someone invested in AI research, I was eager to explore the GPU’s efficacy for tasks involving the training and fine-tuning of expansive transformer models.
Transitioning from an RTX 4060 8 GB to the RTX 5080, I experienced significant reductions in training times for models. However, there are caveats.
At this moment, numerous AI libraries (such as PyTorch, vLLM, Transformers, and Diffusers) are still in the process of being adapted for the latest 50 series GPUs. While nightly builds for PyTorch are available via Hugging Face, some dependencies remain unaddressed, rendering certain model runs, especially with libraries like Unsloth and vLLM, unsupported.
For example, I had to craft my own training code for BERT to execute fine-tuning due to these limitations. Basic inference work with Transformers operates successively, accommodating LLMs with up to 7B parameters using 8-bit quantization. However, for reinforcement learning algorithms like Unsloth, compatibility is lacking. Consequently, I am abstaining from including dedicated AI benchmarks in this review.
If your primary goal for acquiring the RTX 5080 is AI performance, proceed with caution! Currently, the RTX 4080 Super may provide a more effective solution. Despite the powerful nature of the 5080, my preliminary tests—the fine-tuning of DeBERTa and RoBERTa—indicate it can rival the A6000 in training speed. However, the 16 GB VRAM limitation is a potential constraint for those handling larger scale LLMs.
Final Considerations: Is the RTX 5080 Worth It?
Overall, my experiences with the RTX 5080 yield mixed conclusions. Despite the card’s impressive performance, the comparatively small performance gap from the previous generation renders it feel more aligned with the RTX 4080 Ti rather than representing a groundbreaking evolution in GPU technology. Nvidia’s promises of substantial performance enhancements come with the caveat of AI-derived improvements.
While DLSS remains a notable feature, discerning users cannot ignore its inherent complications. Subtle visual artifacts persist, and frame generation does not alleviate the challenges stemming from limited rendering capabilities, particularly in demanding offerings such as *Cyberpunk 2077* and *Spider-Man 2*.
Should you invest in the RTX 5080? Your decision hinges on your current setup. Users migrating from high-performance GPUs like the RTX 4080 or RTX 3080 Ti may find it prudent to wait for a more robust refresh such as the 5080 Super or Ti for a notable upgrade. In contrast, users contemplating an upgrade from older GPUs, like the 3070 or 2080, may find significant value in transitioning to the 5080.
Regarding AI capabilities, the RTX 5080 stands out as the top choice under $1,000. Although AMD Radeon offerings may seem appealing, the complications surrounding ROCm limit their utility. For LLM enthusiasts or smaller research labs with restricted funding needing to fit work within 16 GB of VRAM, the 5080 is certainly a worthy consideration.
