AMD Radeon PRO W6800 vs AMD Radeon HD 7770 (GHz Edition)

The AMD Radeon PRO W6800 is a workstation graphics card that launched in Q2 2021 with a MSRP of $2,249. It is built on the RDNA 2.0 GPU microarchitecture (codename Navi 21) and is manufactured on a 7 nm process.

Memory

The PRO W6800 has 32 GB of GDDR6 memory, with a 2,000 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 512 Gb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.

Cores and Clock Speeds

The PRO W6800 includes 3,840 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 2,075 MHz and can dynamically boost its clock speed up to 2,320 MHz. Complementing the processing units are 240 texture mapping units (TMUs) for efficient texture filtering and 96 render output units (ROPs) for pixel processing. Additionally, the GPU features 60 ray accelerators dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The PRO W6800 occupies 2 PCIe expansion slots. It supports mini-DisplayPort 1.4a display connections. AMD recommends a power supply of at least 600 W to handle the GPU's thermal design power (TDP) of 250 W.

Benchmark Performance & Value

The PRO W6800 has the 30th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 42.45% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 44,404 score and $2,249 launch price (MSRP) gives it a performance per dollar of 19.74. This is the 86th best in value for the 3DMark 11 Performance GPU benchmark.
