GVCS001 - The Compute Architecture of Intel® Processor Graphics Gen8 (https://intel.activeevents.com/sf14/connect/sessionDetail.ww?SESSION_ID=1312)
Hauptneuerungen:
5.1 KEY CHANGES IN INTEL® PROCESSOR GRAPHICS GEN8
Intel® Processor Graphics Gen8 includes many refinements throughout the micro architecture and supporting software. It also includes several major new features and changes over Intel® Processor Graphics Gen7.5. To briefly summarize, these changes include:
- Gen8’s micro-architecture throughput for 32-bit integer computation has doubled.
- Gen8 has added native 16-bit floating-point support to the Execution Units.
- For some Gen8-based products, the write bandwidth from GTI has doubled.
- Coherent shared virtual memory between CPU cores and Intel® Processor Graphics Gen8 has been implemented, enabling seamless sharing of pointer rich data structures.
- For many Gen8-based products, 8 execution units are now instantiated per subslice. This can improve compute throughput as data port and sampler are now shared by fewer execution units. (Gen 7.5 was 10 execution units per subslice.)
- For many Gen8-based products, 3 subslices are now instantiated per slice. This enables new product configurations, and instantiates more samplers per slice, and more concurrent memory interfaces to L3 and SLM. (Gen 7.5 was 2 subslices per slice.)
- Gen8 has increased the L3 data cache capacity and improved local bandwidth between EUs and L3 data cache.
