The AMD Radeon PRO W6800X Duo graphics card that features two Big Navi 21 GPUs outperformed NVIDIA’s GeForce RTX 3090 and RTX A6000 at the Octane Render benchmark. The benchmarks posted by Bare Feats show more than Octane Render and also compare the monster card in other content creation apps with previous Pro and RX cards.
The $ 5,000 AMD Radeon PRO W6800X Duo graphics card is 14% faster than the NVIDIA RTX A6000
The AMD Radeon PRO W6800X Duo graphics card is the only dual-chip graphics card available in the RDNA 2 family and is exclusive to the Apple Mac Pro. The card was announced last month and costs $ 5,000 to buy at the Apple Store. The card comes in the MPX module and is only compatible with the Mac Pro 2019 system. Here are some of its highlights:
- Two W6800X GPUs, each with 60 computing units and 3840 flow processors
- 64 GB of GDDR6 memory (32 GB per GPU), each with a memory bandwidth of 512 GB / s
- Up to 30.2 single-precision teraflops or 60.4 medium-precision teraflops
- Four Thunderbolt 3 ports and one HDMI 2.0 port on the card
- Four DisplayPort connections routed to the system to support internal Thunderbolt 3 ports
- Support for up to eight 4K screens, four 5K screens or six XDR Pro Display
- The full-height MPX module fills an MPX bay and uses additional PCIe power and bandwidth
- The Onboard Infinity Fabric Link connection connects two W6800X GPUs of up to 84 GB / s in each direction; The Infinity Fabric Link external connection allows two W6800X Duo modules to connect four W6800X GPUs
Specifications of the GPU AMD Radeon PRO W6800X Duo
The flagship variant of all is the Radeon Pro W6800X based on the Big Big Navi 21 GPU, which offers up to 64GB of GDDR6 memory and two 60 CU GPU arrays offering a total of 120 computing units or 7680 cores. The clock speed of each core is maintained at 1979 MHz, offering up to 30.2 TFLOP of FP32 and 60.4 TFLOP of FP16 computing power. The card offers up to 1 TB / s of memory bandwidth with its 256-bit dual bus interface. The two reduced Navi 21 GPU arrays should bring the total power of the DUO to about 400W.

AMD Radeon PRO W6800X Duo GPU Reference Settings
So, coming to benchmarks, the AMD Radeon PRO W6800X Duo was tested in several tests and the main one we will focus on is Octane Benchmark, which generally offers better performance on NVIDIA RTX cards. The Radeon PRO finished the performance in 14 seconds with a score of about 717 points. NVIDIA’s fastest workstation card, the RTX A6000 finishes the same rendering in 16 seconds (628 scores), while the fastest gaming graphics card, the RTX 3090, just plays in 15.2 seconds ( 662 scores).
- AMD Radeon PRO W6800X Duo – 717 points / 14 seconds
- NVIDIA GeForce RTX 3090 – 662 points / 15.2 seconds
- NVIDIA RTX A6000 – 628 points / 16 seconds
This makes the AMD Radeon PRO W6800X Duo 14% faster than the NVIDIA RTX A6000 and 8% faster than the RTX 3090. Now, in terms of pricing, the Duo costs a lot more considering that the The A6000 can be found for about $ 4500-5,000 US dollars while the RTX 3090 has a PVP of US $ 1499, but even with inflated prices it can be found between 2000 and 3000 US dollars. Compared to the state-of-the-art AMD PRO Vega II Duo, the new Navi 21-based solution is 18% faster and 37% faster compared to the Radeon RX 6900 XT (individual GPU).
