RTX 5090 vs RTX 4090: Efficiency Comparison at Same Power Level
Reviews of the RTX 5090 have been released, and for those who seek top-tier performance without worrying about price or energy use, Nvidia has truly outdone itself with the RTX 5090. This graphics card excels in both rasterization and ray tracing, offering unmatched capabilities at 4K resolution. With the addition of DLSS 4, this GPU can achieve over 200 FPS in 4K gaming for titles that utilize Nvidia’s Multi-Frame Generation technology.
Performance Comparison
However, the RTX 5090 does not represent as significant an improvement over the RTX 4090 as the RTX 4090 did compared to the RTX 3090. In our evaluations, the new GPU shows an average performance increase of 27% over the RTX 4090. It’s important to note that this performance boost comes with a hefty rise in power usage; the RTX 5090 has a power rating of 575 W, compared to the RTX 4090’s 450 W.
Power Normalization Insights
This raises an intriguing question: How does the performance of the RTX 5090 stack up against the RTX 4090 when both cards are adjusted for power consumption? Luckily, ComputerBase has conducted tests, and the findings are quite enlightening.
Their research indicates that the RTX 5090 achieves an average of 17% more FPS compared to the RTX 4090 in rasterization tasks when both GPUs are limited to 450 W. This means that when the RTX 5090 is restricted to using 125 W less power, it experiences an 8% decline in performance.
CUDA Cores and Performance
The 17% increase in performance at 450 W is particularly noteworthy, especially since the RTX 5090 contains 33% more CUDA cores than the RTX 4090. One might expect a more significant performance disparity than the observed 17% when the power advantage of the RTX 5090 is negated. That said, the slightly lower clock speeds of the RTX 5090 (113 MHz less) likely play a role in limiting its overall performance.
In conclusion, it appears that Nvidia is relying on sheer power to maintain a competitive edge for the RTX 5090 over the RTX 4090. However, this approach may not bode well for the efficiency of the GPU, as the RTX 5090’s performance scales linearly with thermal design power (TDP)—showing a 27% performance increase for a 28% increase in energy consumption. For context, the RTX 4090 boasts over a 50% performance lead compared to the RTX 3090, with only a 29% higher TDP.

Nvidia DLSS 4 Multi-Frame Generation Might Reach Beyond RTX 50
Nvidia is banking on the allure of DLSS 4 multi frame generation to persuade customers to move up to the RTX 50 series. This technology is unique to the new graphics cards, with the RTX 5080 and RTX 5090 scheduled for release on January 30th. In a recent chat with Digital Foundry, Nvidia’s Bryan Catanzaro offered a glimmer of hope to gamers, suggesting that the standout feature of DLSS 4 might eventually be available for the RTX 30 or RTX 40 series.
Advantages Beyond Multi Frame Generation
While multi frame generation is the star of the show, it’s not the only benefit of Nvidia’s DLSS 4. Other features, such as Super Resolution and Ray Reconstruction, will be improved for the RTX 30 and 40 series as well. However, the enhanced frame generation is expected to deliver significant performance boosts in the upcoming graphics cards. These improvements mainly come from smarter AI, which enhances speed and efficiency. Since multi frame generation relies less on the hardware, it faces fewer obstacles regarding backward compatibility.
Optimistic Outlook for Older Cards
During the discussion with Digital Foundry, Bryan Catanzaro acknowledged that multi frame generation might make its way to older Nvidia graphics cards. Although the company is concentrating on the RTX 50 series, this focus might shift with proper optimization. Nevertheless, gamers should temper their expectations. Early performance tests indicate that the RTX 5080 and RTX 5090 significantly depend on the new DLSS 4 feature to achieve the claimed performance improvements. If multi frame generation becomes available for older GPUs, the incentive to upgrade could diminish.
Currently, owners of the RTX 30 series are limited to using FSR 3, AMD’s version of frame generation. The actual performance of DLSS 4 multi frame generation in practical situations will be more evident soon. Review embargoes lift on January 24th for the RTX 5090 and on January 30th for the RTX 5080.

Nvidia RTX 5090D vs RTX 4090: 20% Gaming Performance Boost
It seems that Nvidia has not pleased the gaming community with its reliance on AI-powered frame generation to boost the performance of its new RTX 5090, RTX 5080, and RTX 5070 GPUs. The question of whether DLSS 4 can win over gamers is still open, but it’s evident that the actual performance gains from the Blackwell architecture are not as impressive as first expected.
Performance Insights
We have some preliminary insights into how the GeForce RTX 5090 performs in Cyberpunk 2077, both with and without DLSS 4 and MFG. However, analyzing just one game does not provide a complete picture. Thanks to discussions on Chiphell’s forums, a reviewer has managed to test the RTX 5090D, which is a variant tailored for the Chinese market, and has shared key details from their review. For those unfamiliar, the RTX 5090D is like the standard RTX 5090, but has lower AI TOPS and a 3-second limit for AI and crypto workloads.
Modest Gains
The reviewer found that the performance boost with this generation is, as expected, quite modest. With DLSS and ray tracing disabled, the Nvidia GeForce RTX 5090D outperformed the previous model by about 20%. While this isn’t terrible for a new generation, many in the gaming community anticipated a more significant improvement. However, when DLSS 4 and MFG were set to their highest settings, the reviewer reported that the RTX 5090D performed nearly as well as Nvidia had claimed.
Overclocking Details
Additionally, the Nvidia GeForce RTX 5090D appears to lack adjustable power limits. While there could be possibilities for such adjustments in the future, they seem slim. The reviewer also managed to overclock the card to 2600 MHz, while reducing the memory speed, leading to a memory bandwidth of 896 GB/s that effectively negated the advantages of GDDR7. In comparison, the RTX 4090 was overclocked to about 2610 MHz with a memory bandwidth of 912 GB/s. The testing setup featured a Ryzen 7 9800X3D CPU with memory running at 6000 MHz. Although the exact FPS numbers in-game were not disclosed, this omission is disappointing yet understandable.

Nvidia DLSS 4: 8x Gaming Performance Boost for GeForce RTX GPUs
Nvidia has unveiled the fourth version of its Deep Learning Super Sampling (DLSS) technology. This new update claims to offer a frame rate that is over eight times higher along with latency that is about half of what native rendering provides. A comparison video from Nvidia demonstrates that the frame rate achieved by the new DLSS is set to double compared to DLSS 3.
Enhanced Frame Generation
To achieve these impressive results, Nvidia has included “Multi Frame Generation” within DLSS Frame Generation. Unlike previous versions, DLSS 4 now generates three-quarters of all displayed frames using AI, instead of just every second one. Nvidia notes that this was not feasible before due to the strain it would place on GPUs, which would reduce output frame rates. However, with new advancements in the GeForce RTX 5000, Multi Frame Generation has become achievable.
Improved Performance
The new AI model for Frame Generation operates 40% faster while consuming 30% less graphics memory. For instance, in the game Warhammer 40K: Darktide, Nvidia asserts that DLSS 4 can deliver a frame rate increase of 10%, even when using conventional Frame Generation, saving 400 MB of graphics memory in the process. When paired with the GeForce RTX 5000, DLSS 4 can compute nearly 94% of all pixels using AI instead of relying on native rendering.
Significant Frame Rate Boosts
The impact on performance is substantial. Benchmarks indicate that, depending on the title, DLSS 4 can boost frame rates by anywhere from just under 370% to as much as 720%, translating to nearly four times to over eight times the original rate.
Even though Multi Frame Generation is exclusive to the GeForce RTX 5000, users with older graphics cards, even those as far back as the GeForce RTX 2000, will still find advantages with DLSS 4. This is because the AI models for standard Frame Generation, DLSS Ray Reconstruction, DLSS Super Resolution, and DLSS Edge Smoothing (DLAA) have all seen enhancements.
Broad Game Support
Nvidia reports that more than 75 games now embrace DLSS, featuring major titles like Alan Wake 2, Black Myth: Wukong, and Cyberpunk 2077.
