They can provide very competitive performance with excellent consumption.
In terms of absolute performance, the NVIDIA GeForce RTX 4090 with Lovelace architecture will certainly be the best in this generation of video cards, but there is no need to bury the competitor AMD. As promised, the company introduced the first video cards using the RDNA3 architecture, which will be released on December 13 Radeon RX 7900 XTX And the Radeon RX 7900 XT They’ll cost $999 / $899, respectively. Accordingly, even the top model will be cheaper than the GeForce RTX 4080 arriving in mid-November for $1,199.
The interesting thing about RDNA3’s graphics architecture is that it uses a chiplet design instead of a single one: the graphics processor on the cards consists of several chips rather than one large chip, and its components are connected to a data rail capable of 5.3 TB/s. This is useful for several reasons: on the one hand, the architecture can be changed to different performance levels more easily, on the other hand, it can be more energy efficient, and on the third hand, different chips can be manufactured using different manufacturing techniques, which can reduce the cost of production and scrap rate.
According to AMD’s claim, the best graphics processor with RDNA3 architecture is capable of performing 61 TFLOPS, which is a 2.7 times improvement over the RDNA2 used in the Radeon RX 6000 cards, while at the same performance it can appear 54% better performance / consumption value.
Unlike the NVIDIA Lovelace architecture, RDNA2 already supports the DisplayPort 2.1 specification, and similarly with its competitors, simultaneous encoding and decoding of AV1 codec videos are supported. Theoretically, the performance of the ray tracing display has doubled, according to them, it can be almost at the level of GeForce RTX 3000 cards, but it will not be able to compete with the new RTX 4000 models.
AMD has been very vocal about the performance of its recently announced Radeons, only giving specific information about the Radeon RX 7900 XTX, which can be 50-70 percent faster in 4K gaming than the current top-of-the-line Radeon RX 6950 XT. To give a specific example, Cyberpunk 2077 runs at an average of 62 frames per second in 4K resolution, with ray tracing and FSR playback, so based on the data, it could provide performance comparable to that of the GeForce RTX 3090 Ti.
