In a significant stride in the graphics processing unit (GPU) landscape, AMD has launched the Radeon RX 7900 GRE, its fourth graphics card under the RDNA 3 architecture. This card, positioned in the mid-to-high-end market, is priced at 5299 yuan. It’s the first of its kind in the Radeon RX 7000 series and is strategically designed to compete with NVIDIA’s GeForce RTX 4070.
The RDNA 3 architecture introduces several enhancements and novel features. Notably, it includes the second-generation Infinity Cache, a feature that debuted in the RDNA 2 architecture. AMD reports that this updated Infinity Cache offers 2.7 times the bandwidth of its predecessor, thereby boosting gaming frame rate performance.
The Compute Unit (CU) architecture in RDNA 3 has also seen significant changes. While each CU in the previous architecture contained 64 stream processors, in RDNA 3, these processors can execute two instructions in a single cycle. This effectively doubles the computational power of each CU.
In a first for AMD, AI units, which are becoming increasingly crucial in GPUs, have been incorporated into the RDNA 3 architecture. According to AMD, each CU in RDNA 3 is equipped with two AI accelerators.
The Radeon RX 7900 GRE also showcases improved ray tracing performance. The second-generation ray accelerators have been refined, theoretically providing a 50% performance boost for each CU and handling an additional 50% of rays.
Radeon RX 7900 GRE Specs
In terms of specifications, the Radeon RX 7900 GRE comes with the Navi 31 GPU core, housing 80 CU units, 80 ray accelerators, 160 AI accelerators, and 5120 stream processors. The GPU core base frequency is 1287MHz, with the game and boost acceleration frequencies clocking in at 1880MHz and 2245MHz, respectively. The card is equipped with 16GB of GDDR6 memory, offering a memory bandwidth of 2265.6 GB per second.
In several tests, particularly at 2K and 4K resolutions, the Radeon RX 7900 GRE outperforms the GeForce RTX 4070. The card also demonstrates competitive performance in ray tracing games, even surpassing the RTX 4070 in some instances.
Radeon RX 7900 GRE Design
From a design perspective, the Radeon RX 7900 GRE is quite appealing, featuring a pure black design that is sure to catch the eye. The card’s size and texture are well-proportioned, and it is compatible with most ATX or MATX cases. The card measures 2689751mm and weighs a mere 1.14KG.
The card’s I/O interface includes 1 HDMI 2.1, 2 DP 2.1, and 1 Type-C interface. The Type-C interface can be used for charging mobile phones or providing a one-line function for portable displays, transmitting video signals, and supplying power with a single cable.
In conclusion, the Radeon RX 7900 GRE is a strong contender in the mid-to-high-end graphics card market. It offers impressive performance and innovative features at a competitive price point. Its performance in 2K and 4K gaming, as well as its ray tracing capabilities, make it a worthy competitor to NVIDIA’s offerings. With its appealing design and advanced features, the Radeon RX 7900 GRE is poised to make a significant impact on the GPU market.
