Imagination introduced the CXT architecture and a 6-step radius tracking classification

The Imagination CXT is designed to fit and scale up for mobile use.

Imagination is a true pioneer in real-time beam tracking, introducing a working iron back in 2016. The company’s PowerVR GR6500 graphics chip accelerated more phases than current PC graphics solutions, but the solution did not gain popularity.

Now Imagination has released not only new iron, but also simple self-classification for different levels of radius tracking solutions. According to the company, radiation monitoring can be divided into six different levels:

  • 0 – Processor-rotating beam tracking
  • 1 – Programmable beam tracking with video card
  • 2 – Acceleration of Ray / Box and Ray / Triangle inspections
  • 3 – Bounding Volume Hierarchy (BVH) processing with accelerators
  • 4 – BVH processing and coherent beam sorting with accelerators
  • 5 – Processing and creating a coherent BVH with accelerators

AMD’s RDNA2 architecture ranks in Category 2, NVIDIA and Intel in Category 3, and Imagination’s new CXT Series GPUs in Category 4.

Imagination’s new CXT series was able to slip underneath most surveys earlier this month, although the company has raised its profile recently. The graphics chips in the company’s BXT architecture have been seen implemented by InnoSilicon in at least one and possibly two Chinese-made graphics cards.

The CXT core consists of a total of six Unified Shading Cluster units, six Texture Processing Units, three Geometry Rasterizer units, and three Ray Acceleration Cluster units that share the L3-level cache and firmware unit, which is crossed into the CXT RT3. In its 1 GHz mobile configuration, one core is capable of approximately 1.5 TFLOPS FP32 performance, 6 TOPS INT8 performance, and 1.3 GRays / s and 16 GBoxTests / s readings in beam tracking. However, it should be noted at this point that GRays / s is not based on any standard measurement and may not be comparable with similar values ​​from other manufacturers.

A single CXT series GPU can have a maximum of four CXT cores, which the company calculates are capable of higher clock speeds of approximately 1.5 GHz with a higher power budget and thus more than 9 TFLOPS performance with FP32 resolution and radius tracking of 7.8 GRays / s & 96 GBoxTests / s figures. Imagination licenses the architecture to its customers and is designed to adapt to any process from less than 12 nanometers.
