NVIDIA RTX A6000 vs NVIDIA GeForce GTX 780 Ti

The NVIDIA RTX A6000 is a workstation graphics card that launched in Q4 2020 with a MSRP of $4,649. It is built on the Ampere GPU microarchitecture (codename GA102) and is manufactured on a 8 nm process.

Memory

The RTX A6000 has 48 GB of GDDR6 memory, with a 2,000 MHz memory clock and a 384 bit interface. This gives it a memory bandwidth of 768 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 RTX A6000 includes 10,752 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,410 MHz and can dynamically boost its clock speed up to 1,800 MHz. Complementing the processing units are 336 texture mapping units (TMUs) for efficient texture filtering and 112 render output units (ROPs) for pixel processing. Additionally, the GPU features 336 tensor cores optimized for AI-accelerated workloads and 84 RT cores dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The RTX A6000 occupies 2 PCIe expansion slots. It supports DisplayPort 1.4a display connections. NVIDIA recommends a power supply of at least 700 W to handle the GPU's thermal design power (TDP) of 300 W.

Benchmark Performance & Value

The RTX A6000 has the 26th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 48.72% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 50,957 score and $4,649 launch price (MSRP) gives it a performance per dollar of 10.96. This is the 97th best in value for the 3DMark 11 Performance GPU benchmark.
