Tesla M40 GPU Core

Shader units and compute resources

The NVIDIA Tesla M40 GPU core specifications define its raw processing power for graphics and compute workloads. Shading units (also called CUDA cores, stream processors, or execution units depending on manufacturer) handle the parallel calculations required for rendering. TMUs (Texture Mapping Units) process texture data, while ROPs (Render Output Units) handle final pixel output. Higher shader counts generally translate to better GPU benchmark performance, especially in demanding games and 3D applications.

About NVIDIA Tesla M40

The NVIDIA Tesla M40 delivers a solid compute-to-dollar ratio for deep‑learning workloads that demand raw throughput without the premium of newer Ampere cards. With 12 GB of GDDR5 memory and a 948 MHz base clock, its Maxwell 2.0 architecture still punches above its weight in FP32 performance. At a TDP of 250 W, the card fits comfortably in most workstation power budgets, keeping operational costs manageable. Benchmarks show a Vulkan score of 44,602 and an OpenCL score of 39,192, numbers that translate into respectable training times for medium‑sized models. When you factor in the typical resale value of older Tesla GPUs, the effective cost per teraflop can be lower than many contemporary consumer GPUs. This makes the Tesla M40 a compelling choice for budget‑conscious research labs that need stable, PCIe 3.0 x16 connectivity.

In terms of competition, the Tesla M40 sits between the older Tesla K80 and the newer RTX A6000, offering better power efficiency than the K80 while costing a fraction of the A6000. For users focused on longevity, the 28 nm process and mature driver stack mean fewer firmware surprises and longer support windows from NVIDIA. Pairing the card with a high‑bandwidth CPU like an AMD EPYC 7542 and fast NVMe storage can help mitigate the memory bandwidth ceiling of GDDR5. Additionally, a robust cooling solution preferably a dual‑fan or liquid‑cooled bracket will keep the 250 W draw within safe thermal limits for sustained training runs. The NVIDIA Tesla M40’s PCIe 3.0 interface also ensures compatibility with most server motherboards, simplifying upgrades and scaling. Overall, the card remains a cost‑effective workhorse for inference workloads and legacy model pipelines that don’t require the latest Tensor Cores.

  • Consider the Tesla K80 for an even lower entry price.
  • Upgrade to an RTX A6000 if you need cutting‑edge Tensor Core performance.
  • Pair with an AMD EPYC 7542 or Intel Xeon Scalable CPU for balanced throughput.
  • Use dual‑fan or liquid‑cooling solutions to maintain optimal temperatures.
  • Install NVMe SSDs to reduce data bottlenecks during large dataset training.
