One of the main factors differentiating the RTX 4090 and RTX 5090 is their CUDA cores and boost clock speeds. The RTX 5090 features a significant increase in processing power with 21,760 CUDA cores, compared to the RTX 4090’s 16,384 cores. This substantial boost enables enhanced gaming performance, particularly noticeable at 4K and 8K resolutions.

The number of Streaming Multiprocessors also plays a crucial role in GPU performance. The RTX 5090 houses 170 Blackwell Streaming Multiprocessors (SMs), marking a 33% increase from the 128 SMs found in the RTX 4090. This augmentation increases the total number of CUDA cores, tensor cores, RT cores, and other related units, driving overall performance (BOXX).

When it comes to clock speeds, the RTX 5090 offers a 27% improvement, featuring boost clock speeds of 2407MHz compared to 2520MHz in the RTX 4090. This increased clock speed further contributes to the enhanced capabilities of the RTX 5090.

Memory and Bandwidth

Memory and bandwidth are critical aspects of GPU performance, especially in high-demand gaming and professional applications. The RTX 5090 is equipped with GDDR7 memory, touted as the "world's fastest memory," capable of speeds up to 30Gbps and delivering up to 1.8TB/s of memory bandwidth. This represents a 33% increase in VRAM compared to the RTX 4090, which utilises GDDR6X memory (BOXX).

The increased VRAM and higher memory bandwidth of the RTX 5090 enable it to handle tasks that involve next-gen ray tracing, AI-powered graphics, AI-assisted video editing, real-time 8K video editing, and faster 3D rendering for cinematic production. This makes the RTX 5090 an extremely capable choice for both gaming and professional workflows.

Gaming Performance

Frame Rates Comparison

When comparing the frame rates of the NVIDIA RTX 4090 and RTX 5090, it's evident that the RTX 5090 holds a significant edge over its predecessor. The RTX 5090 delivers up to twice the performance of the RTX 4090 in graphically intensive games such as Cyberpunk 2077 and Alan Wake 2. This makes it an appealing choice for gamers seeking the highest frame rates in modern titles (RTX 4090 vs RTX 5090 benchmarks).

Ray Tracing Capabilities

Ray tracing is another crucial area where the RTX 5090 outperforms the RTX 4090. The RTX 5090 demonstrates a 66% improvement in ray tracing performance over the RTX 4090, thanks to the advancements in its 3rd-gen RT cores which deliver higher TFLOPS. This allows for more realistic lighting, shadows, and reflections in supported games.

The RTX 5090's ability to handle the performance hit from ray tracing with its Blackwell architecture is especially notable. For instance, in Metro Exodus with Ultra-quality RT effects enabled, the RTX 5090 experiences a drop in frames per second from 163fps to 117fps, compared to the RTX 4090's drop from 135fps to 87fps (RTX 4090 vs RTX 5090 release date).

For gamers heavily invested in the latest graphics advancements, the RTX 5090 offers superior performance both in regular frame rates and ray tracing capabilities. More detailed specifications can be explored in our article on rtx 4090 vs rtx 5090 specs.

Power Efficiency and Consumption

Understanding the power demands of the RTX 4090 and RTX 5090 is crucial for PC gamers and tech enthusiasts who desire optimal performance while ensuring their systems are adequately powered.

TDP Rating

Thermal Design Power (TDP) is a key consideration when evaluating the power efficiency and consumption of a GPU. The TDP rating indicates the maximum amount of heat a GPU needs to dissipate to function effectively.

The RTX 5090 boasts a TDP of 575W, a significant increase from the RTX 4090’s 450W (9meters.com). This increase in power demand showcases the advanced capabilities and higher performance metrics of the newer GPU. Notably, the RTX 5090 can consume up to 575W during high-demand gaming scenarios, such as when running Cyberpunk 2077, where it peaks at 578W (Rock Paper Shotgun).

Power Supply Requirements

Given the higher TDP of the RTX 5090, it's crucial to pair it with a sufficiently powerful power supply to ensure stable and reliable operation.

For the RTX 4090, an 850W power supply is typically recommended. On the other hand, the RTX 5090 requires a more robust 1000W power supply to support its 575W power consumption. Upgrading to a 1000W power supply is essential to meet the greater power demands of the RTX 5090 and to avoid potential performance issues (Digital Trends).

AI Computational Performance

When comparing the AI computational performance of the RTX 4090 and RTX 5090, there are several key metrics to consider. The efficiency of Tensor and RT Cores and support for advanced AI algorithms like DLSS play significant roles in shaping the capabilities of these graphics cards.

Tensor and RT Cores Efficiency

The AI computational performance of the GeForce RTX 5090 significantly surpasses that of the RTX 4090. The RTX 5090 offers up to 1676 TFLOPS of tensor FP16 compute and 3352 TOPS of tensor INT8 compute, marking a 154% increase in AI computational performance compared to its predecessor (BOXX). This boost is instrumental in powering AI algorithms, resulting in faster and more intelligent processing.

Meanwhile, the Nvidia GeForce RTX 4090 is no slouch in AI computations, utilising its Tensor Cores to accelerate tasks like deep learning super sampling. However, it is primarily designed for gaming applications, enabling mid-range ray tracing and producing high frame rates (Fibermall).

DLSS and AI Algorithm Support

DLSS (Deep Learning Super Sampling) is a ground-breaking technology that leverages AI to boost frame rates and produce higher-quality images. The RTX 4090 supports DLSS technology efficiently, making it a favourite among gamers for high-performance gaming experiences.

The RTX 5090, however, takes this a step further with support for NVIDIA DLSS 4. This newer version of DLSS leverages the enhanced Tensor Cores' capabilities, providing even higher frame rate acceleration and superior-quality rendering (BOXX).

For users interested in the features of these GPUs for AI tasks and gaming, the RTX 5090's advancements provide a noticeable edge, particularly for developers and gamers looking for the best performance and future-proofing their systems.
