NVIDIA Quadro P4000 8GB

The Quadro P4000 is the single-slot, 105 W Pascal workstation card, and it is in this database because it is still widely rented as a cheap CUDA endpoint rather than because anyone trains on it. It pairs 1,792 CUDA cores with 8 GB of GDDR5 on a 256-bit bus at 243 GB/s, which NVIDIA rates at 5.3 TFLOPS FP32, and it fits in a single slot drawing under the 75 W the PCIe connector supplies plus one six-pin cable. What it does not have is any of the machinery the later architectures are sold on: no Tensor Cores, no structured sparsity, and no published half-precision or double-precision rate of any kind, because Pascal's consumer and workstation dies run FP16 at a fraction of the shader rate and NVIDIA never quoted it. For inference that means everything runs in FP32, at 5.3 TFLOPS, and the 8 GB frame buffer is the real constraint.
