From ExtremeTech: Intel’s Architecture Day 2018 this past Tuesday wasn’t just a CPU show. The graphics market is poised to be a significant component of Intel’s strategy going forward, and the company’s Gen 11 solution looks like it’ll be a potent improvement over Skylake. These improvements are long overdue.
For most of the past twenty years, the phrase “Intel graphics” was a contradiction in terms if you cared about gaming. Starting in 2011, with Sandy Bridge, that began to change. There was a period of roughly five years where Intel’s own solutions were improving at a solid pace. From 2011-2015, IGP performance improved in real terms, meaning Intel’s GPUs got faster more quickly than games demanded additional GPU resources. There were still only a relative handful of titles that could be coaxed into running well, but the situation was improving by the year. And then it stopped. Neither Kaby nor Coffee Lake contained any additional 3D optimizations. After 3.5 years in the proverbial wilderness, Intel wants to change that.
The new Gen 11 GPU is Intel’s first TFLOP-class GPU hardware. It implements a tile-based renderer, presumably to take advantage of tiled rendering’s lower power consumption and increased efficiency. The GPU will contain 24-64 execution units and it packs a 4x larger L3 cache.
Other major features include a tile-based renderer that Intel will be able to enable or disable on a per render-pass basis. Memory compression has also improved, with a claimed best-case performance jump of 10 percent and a geometric mean average of four percent. The new Sunny Cove GT2 configuration intended for desktop will pack 64 EUs, compared with 24 EUs in Skylake’s GT2. That alone should be worth some significant performance improvements, subject to memory bandwidth constraints or other bottlenecks within the core.
