Study Notes
GPU Performance and AI Benchmarks
- GPUs are versatile, capable of accelerating both AI and video processing tasks.
- The performance density of GPUs generally increases over time, shown by the trend of FP32 performance.
- GPUs exhibit high performance density due to their ability to utilize both 8-bit integer units (INT8) and 32-bit floating-point units (FP32).
- GPUs like RTX2080, T4, and V100 offer the flexibility to execute both fixed-point 8-bit and floating-point operations.
- Higher precision in AI benchmarks leads to greater accuracy.
- To enhance compute density, feature size can be reduced.
- Smaller feature sizes allow for greater integration of compute units, increasing GOPS/mm2 (Giga Operations Per Square Millimeter), a measure of performance density.
Specialized Compute Engines for AI
- ASICs (Application Specific Integrated Circuits) are highly specialized for AI benchmarks, achieving high performance density.
- GPUs offer more general-purpose computing capabilities, supporting both AI and graphics processing.
- Processors represent the most general-purpose computing engines.
Data Types and Accuracy
- Data types like FP32 (32-bit floating point) and INT8 (8-bit integer) influence the accuracy of AI benchmarks.
- The accuracy of AI benchmarks is closely related to the data type's precision.
Performance Density and Scaling
- ASICs are specifically tailored for certain data types and precision levels, maximizing performance density (GOPS/mm2).
- Feature map size directly influences the performance density, with smaller sizes enabling greater compute units on the chip.
- Technology scaling, such as the use of 7nm or 8nm CMOS technology, drives performance improvements.
- The trend in compute engines shows a shift towards increasing performance density with decreasing feature sizes.
NVIDIA's V100 and Ampere Series
- NVIDIA's V100 GPU, released in 2017, features around 5000 stream processors, comprised of 80 cores with 64 SIMD (Single Instruction Multiple Data) functional units.
- The Ampere series, released in 2020, represents the latest generation of NVIDIA GPUs, offering significant performance advancements.
- Modern GPUs, such as those in the Ampere series, consist of thousands of functional units, contributing to their enhanced performance density and GFLOPS (Giga Floating-point Operations Per Second) capabilities.
