NVIDIA GeForce RTX 4090D: Next-Generation Power for Gamers and Professionals

April 2025

Since the release of the GeForce RTX 40 series, NVIDIA has continued to amaze with its innovations. The RTX 4090D, introduced at the end of 2024, answers the demands of enthusiasts looking for maximum performance without compromises. In this article, we will explore what sets this GPU apart and who it is suited for.

1. Architecture and Key Features: Ada Lovelace 2.0

The RTX 4090D is built on the updated Ada Lovelace 2.0 architecture, which is an evolution of the original Ada Lovelace. The chips are manufactured using TSMC's 4nm process, allowing for a 15% increase in transistor density compared to the RTX 4090.

Key Technologies:

- DLSS 4.0 — neural network scaling with support for dynamic real-time resolution.

- Third-Generation RTX Accelerators for ray tracing, delivering up to 2x performance increase compared to the RTX 3090 Ti.

- Reflex 2.0 — reducing game latency to 8 ms in "Ultra Low Latency" mode.

- Support for FidelityFX Super Resolution 3.0 from AMD (via open APIs), which is a rarity for NVIDIA cards.

An interesting feature is AI Frame Generation 2.0, which predicts frames with minimal artifacts even at 8K.

2. Memory: 24 GB GDDR7 with Record Speed

The RTX 4090D comes equipped with 24 GB of GDDR7 memory on a 384-bit bus. This is NVIDIA's first GPU to use this type of memory, providing a bandwidth of 1.5 TB/s (compared to 1 TB/s for the RTX 4090).

How does this impact performance?

- In games with 8K textures (e.g., Microsoft Flight Simulator 2024), object loading is 30% faster.

- In professional applications like Blender or Unreal Engine 6, rendering complex scenes is accelerated due to reduced data access times.

3. Gaming Performance: 4K Ultra Without Hiccups

The RTX 4090D is designed for 4K and 8K resolutions, but it also delivers phenomenal results at 1440p.

FPS Examples (4K, Maximum Settings + RT):

- Cyberpunk 2077: Phantom Liberty — 98 FPS (with DLSS 4.0 — 144 FPS).

- GTA VI — 112 FPS (ray tracing on water and glass).

- Starfield: Colony Wars — 120 FPS (DLSS 4.0 + Frame Generation).

Ray tracing remains demanding: without DLSS in Alan Wake 3, FPS drops to 54, but with AI scaling, it rises to 89.

For 1440p, the card is overkill — it consistently delivers 200+ FPS in competitive titles (CS3, Valorant 2.0), which esports players will appreciate with 360 Hz monitors.

4. Professional Tasks: Beyond Gaming

With 18,432 CUDA cores and support for PCIe 5.0, the RTX 4090D excels in:

- 3D Rendering: In Blender, the BMW scene renders in 9.8 seconds (35% faster than the RTX 4090).

- Video Editing: In DaVinci Resolve 19, rendering an 8K video takes half the time compared to the RTX 3090.

- AI Tasks: Training neural networks in TensorFlow is accelerated by 40% thanks to 4 RT Core blocks.

For scientific calculations (e.g., in MATLAB or ANSYS), the card supports OpenCL 3.0 and CUDA 12.5, making it a versatile tool.

5. Power Consumption and Cooling: Powerhouse in a Case

The TDP of the RTX 4090D is 480 watts, which is 30 watts more than the original. This requires a well-thought-out cooling system:

- Recommended Coolers: Liquid cooling (e.g., NZXT Kraken G12) or three-slot solutions like the ASUS ROG Strix LC.

- Cases: At least 2 intake fans and 3 exhaust fans. The best options are the Lian Li O11 Dynamic EVO or Fractal Design Torrent.

Under load, the core temperature rarely exceeds 72°C, but peak values can reach 85°C in poorly ventilated cases.

6. Comparison with Competitors: Who’s Hot on Its Heels?

The main competitor is the AMD Radeon RX 8950 XTX (price: $1500). AMD's advantages include:

- Better energy efficiency (TDP 420 W).

- Support for DisplayPort 2.2 for 8K@240 Hz.

However, the RTX 4090D excels in:

- Ray tracing performance (45% faster).

- DLSS 4.0 vs. FSR 4.0: NVIDIA maintains leadership in image quality.

Among its own, the RTX 4080 Ti Super ($1200) is 25% weaker at 4K but $500 cheaper.

7. Practical Tips: Building the Right System

- Power Supply: Don’t skimp! At least 1000 W with an 80+ Platinum certification (e.g., Corsair HX1000i).

- Motherboard: Must support PCIe 5.0 (ASUS ROG Maximus Z790 Hero).

- Drivers: Use Studio Drivers for applications like Adobe or Autodesk. Game Ready drivers are suitable for gaming.

- Dimensions: Card dimensions are 340 × 140 × 65 mm. Ensure it fits in your case!

8. Pros and Cons: Is It Worth the Upgrade?

Pros:

- Unprecedented performance in 4K/8K.

- Support for new HDMI 2.2 and Wi-Fi 7 standards.

- Ideal for streaming (AV1 encoding).

Cons:

- Price of $1799 (at launch).

- High power consumption.

- Limited availability due to demand.

9. Final Conclusion: Who is the RTX 4090D For?

This graphics card is the choice for those who aren't willing to wait:

- Gamers playing in 4K with maximum RT.

- Professionals who value time in rendering and editing.

- Enthusiasts building a PC “for years” with a power reserve.

If your budget is limited, consider the RTX 4080 Super or AMD RX 7900 XTX. But if you want the best — the RTX 4090D currently has no worthy alternatives.

Memory Bus
?
The memory bus width refers to the number of bits of data that the video memory can transfer within a single clock cycle. The larger the bus width, the greater the amount of data that can be transmitted instantaneously, making it one of the crucial parameters of video memory. The memory bandwidth is calculated as: Memory Bandwidth = Memory Frequency x Memory Bus Width / 8. Therefore, when the memory frequencies are similar, the memory bus width will determine the size of the memory bandwidth.

SM Count
?
Multiple Streaming Processors (SPs), along with other resources, form a Streaming Multiprocessor (SM), which is also referred to as a GPU's major core. These additional resources include components such as warp schedulers, registers, and shared memory. The SM can be considered the heart of the GPU, similar to a CPU core, with registers and shared memory being scarce resources within the SM.
