NVIDIA CMP 40HX

The NVIDIA CMP 40HX is a workstation graphics card that launched in Q1 2021 with a MSRP of $699. It is built on the Turing GPU microarchitecture (codename TU106) and is manufactured on a 12 nm process.

Memory

The CMP 40HX has 8 GB of GDDR6 memory, with a 1,750 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 448 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 CMP 40HX includes 2,304 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,470 MHz and can dynamically boost its clock speed up to 1,650 MHz. Complementing the processing units are 144 texture mapping units (TMUs) for efficient texture filtering and 64 render output units (ROPs) for pixel processing. Additionally, the GPU features 288 tensor cores optimized for AI-accelerated workloads and 36 RT cores dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The CMP 40HX occupies 2 PCIe expansion slots. NVIDIA recommends a power supply of at least 450 W to handle the GPU's thermal design power (TDP) of 185 W.
