Advanced micro-systems announced that it will ship its AMD Radeon RX 7900 XTX and RX 7900 XT graphics cards built on its RDNA 3 graphics architecture on December 13.

The launch comes a month after AMD launched its Ryzen 7000 processors based on the Zen 4 architecture for central processing units. Together, the goal is to push the boundaries of gaming innovation, AMD CEO Lisa Su said during a press briefing.

The cards will be available on December 13, with the XTX available for $999 (with 24GB of memory) and the XT (20GB) at $899. It’s definitely cheaper than Nvidia’s high-end graphics card, the GeForce RTX 4090which started selling for $1,600 in September.

Su said AMD’s goal is to achieve leadership in cross-platform gaming, with design gains not just on the PC, but with gaming-specific hardware such as Valve’s Steam Deck, Microsoft Xbox Series X/S and the Sony PlayStation 5.

The new graphics chips use a “chiplet” design which uses different manufacturing processes such as producing 5 nanometers or 6 nanometers on the same chip. With this technology, modern processors contain multiple chips, called chiplets, rather than a single monolithic chip on a single substrate.

This allows it to achieve 54% higher performance per watt and 18% higher frequency, 2.7x peak bandwidth at 61 teraflops, twice instructions per clock and DisplayPort 2.1 for 4K gaming, a Su said.

“RDNA 3 enables the first chip-based gaming GPU,” Su said.

AMD’s Scott Herkelman introduces the AMD Radeon 7900 XTX graphics card.

The Graphics Compute Die (GCD) is built with 5nm, while the Memory Cache Arrays (MCD, a total of six of the chips) are built with 6nm fabrication. This allows it to get a bandwidth of 5.3 terabytes per second and 24 GB of GDDR6 graphics memory.

In total, RDNA 3 graphics chips will have up to 58 billion transistors.

“It gives us an incredible amount of game performance,” Su said.

The new graphics cards using the chips are the AMD Radeon RX 7900 XTX 24GB and the Radeon RX 7900 XT 20GB.

The cards are optimized for high-resolution gaming with unified compute units with 165% more transistors per square millimeter, said Sam Naffziger, senior vice president and corporate fellow at AMD, during a press briefing. .

“Chiplets are the right process technology for the right job,” he said.

They enable a second-generation Infinity Cache in the MCDs, which means the graphics chip uses less power and less time getting data from cache rather than jumping from chip to DRAM, he said. he declares. Overall, the features allow many times more instructions to be processed per given clock cycle. It also has 2.7x more AI performance with dedicated AI accelerators.

Along with the new graphics chips, AMD unveiled its 8K165 Radiance Display Engine and 4K480 display technologies. This enables better monitors with up to 68 billion colors and 12 bits per channel, and DisplayLink bandwidth up to 54 Gbps.

The new dual media engine with two simultaneous encoding and decoding streams, as well as AI-enhanced video encoding. So it has 1.8 times the motor frequency, which cuts export times for video in half. It has decoupled clocks in different parts of the chip, with a front end running at 2.5 GHz and shaders running at 2.3 GHz. This improves frequency by 15% and saves 25% energy, Naffziger said.

The flagship graphics card with the new graphics chip is the RX 7900 XTX, Scott Herkelman, senior vice president and general manager of the graphics business at AMD, said during a press briefing. It can be paired with the AMD Ryzen 9 7950X processor.

The map is up to 1.7x faster on Cyberpunk 2077 and 1.5x faster on Call of Duty: Modern Warfare II. It has 96 compute units, a 2.3 GHz clock, 24 GB of 384-bit GDDR6 memory and supports 2.1 DisplayPort, AV1 encoding and decoding. And it consumes 355 watts of power. It has the same footprint as the RX 6950 XT card. You remove the old card and insert a new one. In early 2023, new high-resolution displays will start shipping from Samsung to others. Samsung’s Odyssey Neo G9 will be an 8K ultrawide monitor.

At 1440K, the card can run Apex Legends at 300fps. You can play Assassin’s Creed Valhalla – Dawn of Ragnarok at 96 frames per second using DisplayPort 1.4. DirectX ray tracing will be coming to Halo Infinite on AMD hardware.

AMD has partnered with Ubisoft for the Snowdrop engine to enable games like the upcoming Avatar title, and it’s also partnering with Epic Games on Unreal Engine 5. Herkelman said the new cards are the most advanced, with 4K gaming up to 1.4 times faster and up to 355 watts of power consumption. Nvidia’s 4090 comes in at around 440 watts, while the 4080 comes in at 320 watts and $1,200.

Herkelman said in a Q&A that AMD’s graphics chips compete in the sub-$1000 gaming graphics chip segment, which means Nvidia’s 4070 graphics chip and 4080 chips are the targets as opposed to his Nvidia GeForce RTX 4090 flagship graphics chip unveiled in September.

“We obviously would like to be the definitive graphics chip in every esports room,” Herkelman said.

Frank Azor, chief gaming solutions and marketing architect, said AMD is updating its Adrenaline software to run games with a unified user interface and unlocked experience with no signup required. With Open Broadcaster Software, AMD has partnered to enable better video recording and streaming. AMD SmartAccess Video distributes encoding and decoding workloads across the processor and graphics chip to achieve a 30% increase in video processing.

Azor said esports gamers will feel confident enough to go beyond 1080p and still get enough frame rates, with graphics up to 4K gaming at the highest speeds.

Herkeleman said he hopes players can get their hands on the cards in December and more after that, despite the topsy-turvy supply chain picture of recent weeks.
