Next-Gen Intel Arc Gaming GPUs To Utilize Multi-Chiplet Design As Hinted Within Patent
As we get near the launch of Intel’s first main discrete graphics household, the newest patent has revealed that the blue workforce can also be working by itself multi-chiplet GPU design for the next-gen Arc gaming lineup.
Intel’s Subsequent-Gen Arc Gaming GPUs To Leverage From MCM Design, Hints New Patent
Intel is not any stranger to MCM know-how, in truth, their Ponte Vecchio GPU is a full-on Multi-chiplet design although it’s being designed and constructed for the information heart section. Nonetheless, a brand new patent titled ‘Place-Based mostly Rendering Equipment and Methodology for Multi-Die/GPU Graphics Processing’, which has been found by Underfox, talks about how a number of GPUs (MCM) can work collectively for picture rendering.
Patent: Place-based rendering equipment and methodology for multi-die/GPU graphics processing – Intel
Intel MCM GPUs is coming…

Within the patent, Intel proposes an answer to GPU-based graphics rendering by integrating a number of silicon dies right into a single cohesive unit (MCM) able to working a single 3D context to be able to handle manufacturability, salinity, and energy supply issues. It’s said that doing this may require options for a number of lessons of scalability and interconnect challenges to be able to ship one of the best efficiency on a single 3D utility working a number of GPU dies. A few of the algos which are at the moment in use to unravel these issues embody AFR (Alternate Body Rendering) and SFR (cut up body rendering).
The patent particularly talks about integrating tile-based checkerboard rendering, which is a quite common rendering approach used on present GPUs, together with distributed GPU vertex place calculation to allow extra environment friendly scaling on multi-die GPUs. The draw calls are partitioned within the type of puzzles and despatched to the person GPUs on the MCM chip in order that they will execute POSH (Place-Solely Shaders) to find out the full-frame visibility information for the attracts for all dies.
Visibility information then point out if the given primitive is current on every of the pre-defined set of display screen house tiles (checkerboard). When the related visibility information is obtained, every GPU die will use it to restrict the geometry work solely to related primitives and carry out pixel processing work for all of the titles of the checkerboard that it owns. These GPUs work actually quick in engaged on the single-frame.
Total, with such a design, the following technology of Intel Arc gaming MCM GPUs can ship scaled-up efficiency with extra dies being added to the chip with out dealing with the efficiency limitations of current multi-die options equivalent to AMD XDMA/Crossfire and NVIDIA SLI/NVLINK. Intel states that these options are restricted by way of efficiency and whereas one ought to count on an ideal scaling of 200% efficiency with a 2-way and 400% with a 4-way configuration, the precise GPU efficiency is considerably decrease, and most often, non-existent therefore why most GPU makers aren’t investing in these applied sciences any extra.
This might enable the GPU system to scale extra effectively. Now one would say that the 4-GPU/tile resolution that’s used as the instance is official however that is the design that has been proposed and the ultimate variety of GPUs per tile could possibly be vastly totally different.
As talked about earlier, all GPU makers are investing in multi-GPU applied sciences with AMD already out with the world’s first MCM resolution within the type of their Intuition MI200 sequence, NVIDIA releasing Hopper this 12 months with MCM. There are additionally the gaming shopper elements such because the AMD RDNA 3 lineup which is predicted to make the most of the identical tech when it launches later this 12 months. Intel themselves are engaged on a number of tile-based multi-chip CPU & GPU options equivalent to their Meteor Lake and Granite Rapids designs and inside 1 or 2 gens, we might see a correct MCM resolution inside the Arc gaming graphics lineup.
