THE OMG presented this Thursday (3) its new Radeon GPUs and the RDNA 3 architecture for graphics chips. At the event, Lisa Su revealed the RX 7900 XTX and RX 7900 XT video cardshigh-end models from Radeon series.
THE Radeon RX 7900 XTX has 24 GB of VRAM, while the RX 7900 XT it has 20 GB of VRAM — both with GDDR6 type memories. According to Lisa Su, RDNA 3 is also the first chiplet for Radeon graphics cards.
New generation of AMD Radeon GPUs
During her brief presentation, Lisa Su, CEO of AMD, appeared to poke at Nvidia. Su commented that the company maintains the idea of producing video cards with better energy efficiency.
The RX 7900 XTX has 96 computing units (CUs), a clock of 2.3 GHz and support for DisplayPort 2.1 (also present in the RX 7900 XT. The consumption of the video card was 335 W — against 450 W of its competitor, the Nvidia RTX 4090. The RTX 7900 XT has 84 CUs, clocks at 2 GHz and consumes 300 W.
In the presentation of the cards, AMD highlighted that upgrading to the new cards will be easier. The company showed that there was no difference in size and that consumers won’t have to change the PC font — this time making obvious the nvidia nudge.
Both GPUs will be available from December 13th. The RX 7900 XTX will be priced at US$ 999 (R$ 5,112.68 in direct conversion), while the RX 7900 XT model will cost US$ 899 (R$ 4,600.90). There is still no price and release forecast for Brazil.l.
What’s New in the RDNA 3 Architecture
The computational performance of the RDNA 3 architecture jumped from 23 TFLOPS to 61 TFLOPS. AMD revealed that the GPU, manufactured in the 5nm process, has 58 billion transistors. The transistor density is 165% higher than the previous generation.
With these evolutions, the RX 7900 XTX will be 1.7 times faster than the RX 6950 XT, the high-end video card of the predecessor series (RX 6000). The Radeon RX 7900 XTX and XT will be able to stream content in 8K quality at 165 Hz and 4K at 480 Hz.
