RTX 4090 Review & Specifications

The RTX 4090 is based on the Ada Lovelace architecture and manufactured using the 5 nm nm process node. It was launched approximately 3 years, 9 months ago, originally priced at $1599. It features 16384 cores, including 128 compute units (SMs), 512 texture mapping units (TMUs), and 176 render output units (ROPs). For ray tracing and AI-accelerated tasks, it also includes 128 dedicated RT cores and 512 Tensor cores, enabling advanced rendering and upscaling features where supported. It has a base clock of 2235 MHz and a boost clock reaching up to 2520 MHz. The RTX 4090 comes equipped with 24 GB of GDDR6X memory across a 384-bit bus. Memory runs at 1313 MHz and delivers a total memory bandwidth of 1 GB/s.

This GPU has a very high thermal design power (TDP) of 450 W. A PC case with excellent airflow and a high-quality, high-wattage power supply are essential for stable operation.

RTX 4090 Performance

RTX 4090 is an ultra high-end graphics card, achieving a relative gaming performance score of 88.46%. It delivers exceptional 4K performance and is ideal for premium builds with a high-end CPU. Expect 300+ FPS in competitive games or over 100 FPS in AAA titles at 4K with ultra settings.

In terms of memory capacity, the RTX 4090 features an exceptionally high VRAM size of 24 GB. This allows users to push the limits of current-generation software and games. You can comfortably run modern AAA titles at ultra settings with full ray tracing enabled at 4K or 5K resolutions, even while using texture packs, high-resolution assets, and real-time lighting. The GPU also excels in professional workloads such as 3D modeling, video editing at 8K, high-resolution texture baking, and multi-layer compositing in tools like Blender, DaVinci Resolve, or Adobe After Effects. In the domain of AI and machine learning, this level of VRAM supports complex neural networks (e.g., large LLMs, diffusion models like Stable Diffusion XL) with high batch sizes, and seamless multitasking without swapping to system memory. This GPU is also ideal for creators who run multiple high-memory applications simultaneously.

RTX 4090 has a gaming performance-per-price ratio of 24.1%, suggesting lower value in this category. However, its high raw performance makes it a viable choice for users who prioritize gaming power over budget constraints.
