AMD unveiled the RX 7000 series graphics cards
Finally, after a long wait, AMD unveiled the RX 7000 series graphics cards, named RX 7900 XTX and RX 7900 XT, which use the new RDNA 3 architecture. get benifits. This means that the graphics processors of these cards are based on chiplet design and are similar to Ryzen processors. For comparison, we have to say that Nvidia has set the price of RTX 4080 at $1,199 and the 4090 model has gone to the market with a huge price of $1,599. RX 7900 XTX is considered the flagship model of this AMD family, which according to the company's claim, can provide up to 1.7 times faster performance in 4K games than RX 6950 XT. This card has 96 processing units with a speed of 2.3 GHz and 24 GB of GDDR6 memory. The consumption of this card reaches 350 watts, while the RTX 4090 consumes up to 450 watts of energy. This means that in terms of performance per watt, the AMD graphics card appeared better than the Nvidia graphics card.
The RX 7900 XT is naturally weaker and uses 84 GPUs clocked at 2 GHz with 20 GB of GDDR6 memory. Also, its power consumption reaches 300 watts. AMD has announced that the reason for choosing GDDR6 instead of GDDR6X is mainly due to lower energy consumption. You don't need to use special cables to power these cards, and you need to use two normal 8-pin connectors for both. It should be noted that users must use a special 12VHPWR connector to use Nvidia's RTX 4090 card.
In the field of RDNA 3 architecture, exciting numbers have also been proposed. For example, we can point to the promise of a 54% improvement in performance per watt compared to the RDNA 2 architecture. At 4K resolution, AMD says the 7900 XTX can deliver 62 frames per second with ray tracing and FSR enabled. This means that it has less to say in this regard than RTX 4090 and is mainly considered a competitor for RTX 4080.
At 4K resolution for the Call of Duty: Modern Warfare 2 game, we encounter about 306 frames per second, which, of course, is obtained if the FSR feature is activated. The performance of this technology is similar to the DLSS capability of Nvidia graphics cards, which simply means that the game is run at a lower resolution, and then with the help of artificial intelligence, the resolution of the games is increased. AMD has promised to introduce a new generation of FSR for these new graphics cards next year, which will significantly improve its performance. DisplayPort 1.4 placed in new Nvidia graphics can provide a higher refresh rate for 4K and 8K content. Also, like Nvidia, AMD has decided to enable simultaneous decoding and encoding for AV1, which is likely to be of interest to streamers.
According to AMD's announcement, this company has for the first time turned to making a graphics chip based on chiplet design. In this type of design, instead of an integrated chip, several different parts are placed on a common substrate. This technology has allowed AMD, for example, to use 5nm manufacturing technology for the graphics computing unit and to use 6nm lithography for the memory cache unit. AMD has already used this design for Ryzen processors, and companies such as Intel, Samsung, ARM, and Qualcomm are also considering this approach for their chips. AMD has announced that at the beginning, the new architecture of these chips will not cause any particular problem for developers, but with the improvement of software and drivers, their performance will be better.
AMD has also unveiled a software feature called Hypr-RX, which can apply the best settings related to technologies such as FSR with just one click. This means that users don't have to manually manipulate various features to achieve the best framerate.
