AMD Radeon RX 7900 XTX and 7900 XT is now official!
AMD’s new 7000 series GPUs are the world’s first chiplet-based designs, based on the new RDNA 3 architecture. The GPU die is made up of two major components: the Graphics Compute Die (GCD) and the Memory Cache Die (MCD).
The GCD is made using the modern 5nm manufacturing process, whereas the MCD is made using the older 6nm process.
AMD can now mix and match components for different configurations because of the transition to a chiplet-based design. It also enables them to employ several production procedures for each component.
Moreover, smaller pieces also offer higher yields than a single huge monolithic die, allowing the manufacturer to manufacture these parts more cheaply and effectively. The new GCD includes new RDNA 3 compute units, a new display engine, and a new dual media engine.
Each computing unit contains 1.5x VGPR (Vector General Purpose Register), 64 dual issue stream processors with 2x instruction issue rate, 2x AI accelerators with 2.7x performance and a 2nd Gen RT accelerator with 50% greater performance per CU.
Meanwhile, the new MCD has a 64-bit memory controller and a 2nd Generation Infinity Cache for 2.7x peak memory bandwidth.
“These new graphics cards are designed by gamers for gamers. As we were developing the new cards, we not only incorporated feedback from our customers, but we built in the features and capabilities we wanted to use,” said Scott Herkelman, senior vice president & general manager, Graphics Business Unit at AMD
Furthermore, RX 7900 XTX includes 96 compute units, a 2.3GHz game clock, 24GB of GDDR6 384-bit memory with 96MB of Infinity Cache, and a 355W board power limit that can be supplied by two 8-pin connections.
The 7900 XT, on the other hand, has 84 compute units, a game clock of 2.0 GHz, 20GB of GDDR6 320-bit memory with 80MB Infinity Cache, and a board power limit of 300W.
Both cards support the new DisplayPort 2.1 standard, which is only capable of 54Gbps of intermediate UHBR 13.5 bandwidth, as well as a new media engine that can simultaneously encode and decode both 8K60 AV1 and AVC/HEVC.
Surprisingly some first benchmark results from AMD were available this time. In comparison to the 6950 XT, the 7900 XTX is said to be up to 1.6x faster for ray tracing at 4K and up to 1.7x quicker for pure rasterization. But no data was offered for the 7900 XT or the competitors.
“We also realized that we needed to do something different to continue pushing the envelope of the technology, and I’m proud of what the team has accomplished with AMD RDNA 3 and the Radeon RX 7900 Series graphics cards. I can’t wait for gamers to experience the powerhouse performance, incredibly vivid visuals and amazing new features these new graphics cards offer.”
Price and availability
- RX 7900 XT – USD 899 (around PHP 52.5K)
- RX 7900 XTX – USD 999 (around PHP 58.4K)
Both AMD Radeon RX 7900 XT and RX 7900 XTX are set to be available in the market this coming December 13. However, there’s no information yet about their local pricing and availability, so stay tuned!
