Review of video cards Nvidia GeForce RTX 4090 and RTX 4080
Back in 2018, Nvidia introduced the Turning architecture, which changed the real-time 3D graphics industry in many ways. And it was from that time that the possibilities only began to improve, and over time this was reflected in games and professional graphics. Turning initially offered the market hardware acceleration not only for rasterization, but also for ray tracing. And this makes it possible to use it in real time. Also, among the additional innovations, it is worth highlighting the GPU architecture hardware acceleration of AI tasks on tensor cores.
A few years later, the company introduced another architectural solution – Ampere, which until recently was considered the ideal of graphic performance. Thanks to refinement and cooperation in the future, GPUs have received much more performance of mathematical calculations. And now everything is running much faster.
The company calls Ada a real revolution in architecture, but in fact it is just a follower of the ideas of Turning. Of course, performance has increased in many ways, but there are new features and features that make everything much more efficient.
There are also significant changes in the case of DLSS performance improvements. All GPUs of the Ada architecture support the new version of this technique DLSS 3. Its peculiarity is to support the generation of additional frames based on the existing ones.
This is achieved not only thanks to the cores, but also to the improved engine, which is responsible for the synthesis of new frames.
The GeForce RTX 4090 video card is based on three processors:
- AD 102.
- AD 103.
- AD 104.
Also worth considering is the 4080. These are the first of their kind architecture processors designed for wealthy or professional gamers. These options allow you to get the best performance, regardless of the capabilities. Of course, they are intended for 4K resolution and maximum graphics settings.
The GeForce RTX 4090 is the top of the line modern model, while the 4080 is a generation below. But I must say that the manufacturer for some reason called two different video cards the same. Even the chips used here are different. In general, the differences are quite significant. In fact, all changes are reflected in the tables, so that a knowledgeable person can easily understand everything. The changes do not affect only the architecture, and the name.
Why Nvidia did this is anyone’s guess. When choosing, you just need to take into account all the available characteristics and compare options. This will make it possible to understand what the difference is and what will be better in this or that case.
