AMD has released the first GPU designed with Chiplets, the Radeon RX 7900 XTX and RX 7900 XT graphics cards using the new RDNA 3 architecture will be officially launched on 12/13. The RX 7900 XTX is priced at $ 999 and the RX 7900 XT is $ 899.
The RDNA 3 architecture is designed with chiplet. At the core of the chip is the 5nm Graphics Compute Die (GCD) processing process and the surrounding 6 Memory Cache Dies (MCD).
Let RDNA 3 achieve 61 TFLOPS of compute performance, 5.3TB / s of internal chip transmission performance and 24GB of GDDR6 memory and 5.8 billion transistors.
Memory Cache Die (MCD) includes 64-bit Mem Controller and 2nd Generation Infinity Cache, and the total memory bandwidth can reach 5.3TB / s, which is 2.7 times the bandwidth of RDNA architecture 2.
Of course, the RDNA 3 Graphics Compute Die (GCD) has also been completely updated, including the Unified RDNA 3 Compute Units, the new Display Engine and the new Dual Media Engine.
There are dual emission SIMD units in the core, which can have twice the speed of sending instructions and flexibly handle FP, Int, AI and other operations.
This generation has finally added AI accelerators.Each CU has 2 AI acceleration units, which can bring 2.7 times greater AI performance improvement.
The second generation RT Accelerator ray tracing acceleration unit can improve ray tracing performance by 50% for CU, with newly designed instructions and sorting and traversing of ray boxes. However, the detailed architecture update remains to be announced by AMD.
AMD also provides new graphics cards that will support DisplayPort 2.1, and the display bandwidth can reach 54 Gbps, illuminating the ultra-high specs of 8K165 and 4K480. But the supported screens won’t be until 2023.
This generation uses Dual Media Engine, which not only supports the original AVC / HEVC codec, but also adds AVI encoding and decoding functions to support 8K60, as well as AI accelerated video and audio encoding functions.
Additionally, RDNA 3 will utilize decoupled clocks, allowing the GPU Shader to run at 2.3 GHz and the front end at 2.5 GHz, resulting in 25% power savings and 15% clock increase.
Eventually, the raw processing performance of RAND 3 can reach 61 TFLOPS, which is only 23 TFLOPS compared to the previous generation of RDNA 2. It can be seen that the performance of this generation has also been greatly improved.
In terms of performance, the RX 7900 XTX can have a 4K performance upgrade of 1.7x over the previous generation RX 6950 XT.
The RX 7900 XTX will have 96 CU processing units, 2.3 GHz clock, 24 GB of 384-bit GDDR6 memory, and a TBP graphics power consumption of 355 W.
The RX 7900 XT has 84 CU processing units, 2 GHz clock, 20 GB of 320-bit GDDR6 memory, and a TBP graphics card power consumption of 300 W.
In addition, AMD said that the new generation RX 7900 XTX and RX 7900 XT both use 8-pin PCIe power, and there is no need to replace a larger case to upgrade the graphics card, the size of the graphics card is still maintained a 2.5 Width and length of the slot 287 mm.
AMD also claimed that the RX 7900 XTX can play 8K games via FSR, such as Death Stranding Director’s Edition 148 FPS, Hitman 190 FPS, and UNCHARTED: Thief Legend Collection 73 FPS, Assassin’s Creed: Viking Age 96 FPS.
Additionally, 4K ray tracing performance has also been improved, with Dianyu Renke 2077 62 FPS, Dying Light 2 Stay Human 72 FPS, and Hitman 3 89 FPS.
In addition, AMD also expects FSR 3 to increase the performance of FSR 2 by 2 times and will be launched in 2023.
In short, the Radeon RX 7900 XTX and RX 7900 XT graphics cards with the new RDNA 3 architecture will be officially launched on 12/12. The RX 7900 XTX is priced at $ 999 and the RX 7900 XT is $ 899. Interested gamers can wait for the performance enhancement to be shared, and the entire content can reference AMD Presents – together we present the advanced_gaming video.
