AMD tried to divert potential buyers’ attention from the GeForce RTX4080 graphics card launch by introducing the Radeon RX7900 series graphics cards based upon the RDNA 3 architecture two days prior. AMD noted the details which it believes should convince PC owners of its accelerators.
AMD previously confirmed that GeForce RTX 4080 would be the main competitor to the Radeon RX7900 XTX or RX7900 XTX video cards. The GeForce RTX 4090 gaming video card will continue to be the fastest, at least in the foreseeable future.
Radeon RX7900 XTX reference model received a VRM subsystem with 20 phases. This is three more than what was available in the Founders Edition reference edition.
AMD also points out that the new video cards are smaller than its competitors. They are thinner and shorter than the GeForce Radeon RTX 4080 Limited Edition. In addition, unlike GeForce’s RTX 40-series card, Radeon RX7900 XTX, and RX7900 XTX accelerators are equipped both with DisplayPort 2.0 and USB Type C connectors.
AMD reminds us that its new video cards are not compatible with any adapters or new power connectors, unlike other competitors. They come with two 8-pin PCIe Power Connectors. This makes them compatible with all power supplies.
AMD graphics cards are expected to offer more video memory in the $900-$1200 price bracket. The Radeon RX7900 XTX model received 24 GB GDDR6 and the Radeon RX7900 XTX model received 20 GB GDDR6. The GeForce RTX4090 flagship model has 24 GB faster GDDR6X memory, but it is recommended to run at $1600. The GeForce RTX 4080 model, in turn, received “only” 16 GB of GDDR6X at a recommended cost of $1200.
Unfortunately, NVIDIA as well as AMD are still not ready to direct compare the performance between their accelerators. AMD is comparing its RDNA 3 graphics card with its flagship accelerator Radeon RX6950 XT because the GeForce RTX 4080 has yet to go on sale.
