Hi, let me provide some details to answer this question. "Evaluating" a test image in Blender simply boils down to rendering the frame in question. In contrast, NeRF, or in this case Instant NPG, first trains a model to learn the 3D scene, and is then capable of predicting an image, given a camera.
Depending on your hardware, the rendering parameters and the scene complexity (geometry and materials), Blender can take minutes to hours to render a single frame, especially if using Blender's path-tracer, Cycles. When rendering small scenes (simple geometry and materials) with Blender's real-time rasteriser, Eevee, Blender usually performs quite fast. But even with Eevee, rendering a single frame can still take from seconds to minutes.
Instant NGP on the other side, will take from a few seconds to a very few minutes to train its NeRF model, and is then capable of predicting a test image way faster than almost any renderer. Therefore, when testing on hundreds of images, Instant NGP will be drastically faster than Blender.
