RTX4090 here it comes! Simplify the complexity and introduce you to NVIDIA RTX40 series graphics cards

At 11:00 p.m. Beijing time on September 20, 2022, NVIDIA officially released the RTX40 series of graphics cards at the GTC22 conference, which has attracted much attention. We Bubble Network will now refine the key content for you. First, the first batch of RTX40 series graphics cards has launched 3 models, including RTX4090, RTX4080 16GB, and RTX4080 12GB. Among them, RTX4080 16GB and RTX4080 12GB not only have different memory capacities, but also have different GPU specifications. Second, the graphics card price (suggested retail price) RTX4090 - 12,999 yuan RTX4080 16GB - 9,199 yuan RTX4080 12GB - 7,199 yuan Third, graphics card specifications We have made a graphics card comparison table, you can see it at a glance. (1) The new generation of GPU architecture is still an SM unit including 128 CUDA cores. (2) The RTX4090 graphics card has 16384 CUDA cores, which is about 1.52 times the number of CUDA cores of the RTX3090Ti graphics card. (3) The AD102 display core with complete specifications has 144 SM units and 18432 CUDA cores. Therefore, the RTX4090 does not use the full specification AD102 display core. In the future, NVIDIA is likely to launch higher-end graphics cards such as the RTX4090Ti. (4) The RTX30 series uses Samsung's 8nm process. To be honest, the power consumption and heat generation are not good enough. Now, the RTX40 series uses TSMC's 4N process, and the performance in terms of power consumption and heat generation is a major attraction. (5) Compared with the RTX30 series, the GPU frequency of the RTX40 series graphics card has been greatly improved, and the Boost frequency of the RTX4080 12GB graphics card has exceeded 2.6GHz. It seems that TSMC's 4N process is indispensable! Fourth, important new technologies RTX40 series graphics cards have two very important new technologies - Shader Execution Reordering (shader execution reordering) and DLSS 3(1) Shader Execution Reordering (shader Execution Reordering) Perform reordering) According to NVIDIA's official introduction, advanced ray tracing needs to calculate the impact of many rays hitting many different material types throughout the scene, creating a series of divergent, inefficient workloads for shaders (shaders are rendering Appropriate shading and color levels are calculated during the 3D scene and used in every modern game). Shader Execution Reordering technology dynamically reorganizes these previously less efficient workloads into more efficient ones. Shader Execution Reordering technology can improve ray tracing performance by up to 3x and increase game frame rates by up to 25%. (2) DLSS 3DLSS, commonly known as "Popeye" by netizens! DLSS is a revolutionary breakthrough in AI-driven graphics that can dramatically improve performance. In layman's terms, DLSS technology can fully release the performance of GeForce RTX series graphics cards, which in turn makes light-chasing games in the new era run more smoothly and with more exquisite picture quality. Powered by the new fourth-generation Tensor Cores and optical flow accelerators on the RTX40 series GPUs, DLSS 3 can use AI to create more high-quality frames without compromising image quality and responsiveness. RTX30 series and RTX20 series graphics cards cannot support DLSS 3. 5. Appreciation of the first non-public graphics cards of the RTX40 series - iGame Vulcan and Neptune In the era of the RTX30 series, iGame's Vulcan and Neptune series graphics cards have left our editors quite good. impression. Now, let's take a first look at the Vulcan Vulcan and Neptune Water God in the RTX40 series era. The iGame Vulcan of the new GeForce RTX 40 series has a more aggressive shape, and the unique iron-colored metal exoskeleton is more aggressive, warning its strong performance. As high-end hardware in the post-cyber era, the series of classic sharp triangular elements will also be perfectly inherited. The dark base color reflects its low-key personality, creating a sharp and cool high-end hardware. "New experience of human-card interaction" will be the core selling point of this new Vulcan, and the more convenient and smarter way of using it will greatly improve the player's experience. Vulcan's exclusive LCD side screen is now reborn, opening the era of "smart screen" for players! It will perfectly interpret the concept of artificial intelligence and human-card interaction. , Vertical two placement methods. The screen display customization function that players are concerned about has also been upgraded. The new generation of Vulcan and the new iGame Center software can customize the content. The resolution of the smart screen 800*216px will display the customized content in higher definition. Overclocking control/global light control/custom display can all be operated through software, and can monitor the running status of CPU and GPU and other hardware. More user-friendly operation and interaction will comprehensively improve the human-card interaction experience! The new Neptune water god uses The silver-white alloy outer armor and the light-colored metal armament have more distinctive modeling characteristics than the previous generation, creating a new form of deep-sea civilization. It is worth mentioning that the iconic feature of Neptune has evolved from the circular eye of the ocean to a double wave curve. The iGame product designer specially designed it with the inspiration of the water flow, and followed the movement rhythm of the water flow to create a new visual language. The new hyperbola brings players a RGB visual feast that runs from left to right. The light effect will flow as quietly as water, gurgling, and simulating the direction of water flow will restore the once glorious Atlantis civilization to the fullest. Presenting an artistic light and shadow feast for players. Under the gentle appearance, there is a cutting-edge temperature control technology from deep-sea civilization. The full-coverage large-size copper bottom will directly touch the GPU heat source, which will be more conducive to transferring the core heat source, whether it is games or high-load scenarios such as content creation. The heat source below can be easily dealt with, and with the 360 ​​cold radiator, it will achieve more efficient heat dissipation performance.
