Actual measurement comparison: why is RTX 4050 and RTX 4080 the best choice for game books?

RTX forty Gamebook The first batch of products of the new generation GPU have basically come into the market. From the entry-level RTX 4050 to the high-end RTX 4080, the new generation GPU can be said to bring a leap in graphics performance to game books. Advantages When DLSS3 is supported, the RTX 40 game book can be said to be greatly improved in light pursuit games. Even the entry-level RTX 4050 can get a very excellent game experience with DLSS3.

So what about the performance of the current mainstream RTX 4050, RTX 4060, RTX 4070 and RTX 4080? How much has it improved compared with the previous generation? Today we are focusing on the new RTX 40 series Notebook computer Perform a systematic test on the performance of the GPU.

First, let's take a look at the basic specifications of four different models of independent graphics cards, as follows:

First, GeForce RTX 4050 notebook The computer GPU has 2560 CUDA cores, 6GB GDDR6 video memory, 113 GPixel/s pixel fill rate, 188.4 GTxel/s texture fill rate, 96bit bus bit width, 2070MHz core frequency, 2000MHz video memory frequency and 2355MHz Boost frequency.

The RTX 4060 notebook GPU has 3072 stream processors, 8GB GDDR6 video memory, 128bit wide video memory, 2175MHz base frequency, and 2370MHz acceleration frequency, which is an obvious evolution of game performance brought about by the improvement of architecture and technology.

GeForce RTX 4070 laptop GPU has 4608 CUDA cores, with core frequency of 2170MHz and Boost frequency of 2275MHz; The video memory is 8GB GDDR6 from Samsung. The video memory bit width is 128bit and the video memory frequency is 2125MHz.

The RTX 4080 notebook computer GPU has a full blood power of 175W, 7424 CUDA cores, 12GB GDDR6 video memory, a pixel fill rate of 154.4 GPixel/s, a texture fill rate of 447.8 GTxel/s, a bus bit width of 192bit, a core frequency of 1510MHz, a video memory frequency of 2250MHz, and a Boost frequency of 1930MHz.

The reason why the performance of the new RTX 40 series notebook GPU has been greatly improved is inseparable from Nvidia's latest Ada Lovelace architecture. It not only has a new SM multi unit stream processor, but also has upgraded the Tensor Core and RT Core. In addition, the DLSS3 technology mentioned above has significantly improved the experience of light chase games. DLSS3 includes frame generation technology, super-resolution technology, and NVIDIA Reflex low latency technology, which can significantly improve performance while ensuring excellent image quality, making panoramic ray tracing games a reality. Among them, the frame generation technology is also known as frame insertion, which realizes the effect that is difficult for human eyes to distinguish through AI. In addition, NVIDIA Reflex low delay technology can minimize the delay caused by frame insertion. With the help of these technologies, DLSS3 can achieve multiple improvements in some game scenarios.

Let's take a look 3DMark The results of each run are compared as follows:

From the three tests of TimeSpy, PortRoyal and FSE, the performance of the RTX 4080 notebook GPU is unparalleled. Compared with the poor price performance of the desktop RTX 4080, the RTX 4080 on the notebook side is really good. The overall performance is about 40% higher than the previous generation flagship RTX 3080Ti, and the performance is excellent.

In addition, because the RTX 40 series graphics card fully supports DLSS3, even the RTX 4050 is comfortable in the light chase game. Let's take Cyberpunk 2077 as an example to see how RTX 4050+DLSS3 works.

1080P resolution+super light pursuit mode, the average frame number can reach 49.41fps under DLSS automatic condition, which is similar to the frame number of RTX 3060 running this game alone.

Then we open the DLSS Frame Generation option in the game settings, and DLSS3 will be enabled. If not, DLSS2 will be the default.

With the same settings, the effect of DLSS3 can be said to be very significant. The average number of frames increases to 73.91 fps, about 50%. This effect can only be said to be too strong.

·Conclusion

It can be seen from the test that if you just play games, it is enough to choose the RTX 4050 model. However, if you have an adequate budget and want to pursue more extreme graphics performance, the RTX 4080 model is absolutely the first choice. After all, the RTX 4060 and RTX 4070 have some overlap with the performance of the previous generation flagship, and the RTX 4080 is a model that completely surpasses the previous generation.
