  Larrabee is the codename for a cancelled GPGPU chip that Intel was developing separately from its current line of integrated graphics accelerators. It is named after either Mount Larrabee or Larrabee State Park in the state of Washington. The chip was to be released in 2010 as the core of a consumer 3D graphics card, but these plans were cancelled due to delays and disappointing early performance figures. The project to produce a GPU retail product directly from the Larrabee research project was terminated in May 2010 and its technology was passed on to the Xeon Phi. [...] Larrabee can be considered a hybrid between a multi-core CPU and a GPU, and has similarities to both. Its coherent cache hierarchy and x86 architecture compatibility are CPU-like, while its wide SIMD vector units and texture sampling hardware are GPU-like. As a GPU, Larrabee would have supported traditional rasterized 3D graphics (Direct3D & OpenGL) for games. However, its hybridization of CPU and GPU features should also have been suitable for general purpose GPU (GPGPU) or stream processing tasks. For example, it might have performed ray tracing "Ray tracing (graphics)") or physics processing, in real time for games or offline for scientific research as a component of a supercomputer. [...] Each core contained a 512-bit vector processing unit, able to process 16 single precision floating point numbers at a time. This is similar to, but four times larger than, the SSE units on most x86 processors, with additional features like scatter/gather instructions and a mask register designed to make using the vector unit easier and more efficient. Larrabee was to derive most of its number-crunching power from these vector units. It included one major fixed-function graphics hardware feature: texture sampling units. These perform trilinear and anisotropic filtering and texture decompression.

  logic and other dedicated scheduling logic. This paper describes a highly parallel architecture that makes the rendering pipeline completely programmable. The Larrabee architecture is based on in-order CPU cores that run an extended version of the x86 instruction set, including wide vector processing operations and some specialized scalar instructions. Figure 1 shows a schematic illustration of the architecture. The cores each access their own subset of a coherent L2 cache to provide high-bandwidth L2 cache access from each core and to simplify data sharing and synchronization. Larrabee is more flexible than current GPUs. Its CPU-like x86-based architecture supports subroutines and page faulting. Some operations that GPUs traditionally perform with fixed function logic, such as [...] 1 Larrabee: A Many-Core x86 Architecture for Visual Computing Larry Seiler1, Doug Carmean1, Eric Sprangle1, Tom Forsyth1, Michael Abrash2, Pradeep Dubey1, Stephen Junkins1, Adam Lake1, Jeremy Sugerman3, Robert Cavin1, Roger Espasa1, Ed Grochowski1, Toni Juan1, and Pat Hanrahan3 Abstract123 This paper presents a many-core visual computing architecture code named Larrabee, a new software rendering pipeline, a many-core programming model, and performance analysis for several applications. Larrabee uses multiple in-order x86 CPU cores that are augmented by a wide vector processor unit, as well as some fixed function logic blocks. This provides dramatically higher performance per watt and per unit of area than out-of-order CPUs on highly parallel workloads. It also greatly increases the [...] sample positions in the primitive. Fixed function logic typically requires FIFOs for load balancing. It can be difficult to properly size these logic blocks and their FIFOs to avoid both wasted area and performance bottlenecks. Larrabee uses software in place of fixed function logic when a software implementation provides sufficient performance. In particular, Larrabee does not include fixed function logic for rasterization, interpolation, or post-shader alpha blending. This allows Larrabee to add new features and optimizations, as well as allowing these tasks to be implemented in different places in the rendering pipeline, depending what is most efficient for a particular application. Implementing them in software also allows Larrabee to allocate to each the performance it requires,

Jaycen Joshua at Larrabee [...] ### Larrabee North [edit] In 1991, Larrabee Studio acquired another studio located at 4162 Lankershim Boulevard in North Hollywood and renamed it Larrabee North. Originally founded by Len Kovner in 1973 as Davlen Sound Studios, Giorgio Moroder purchased the space in 1983 and renamed it Oasis Recording Studios. Teddy Riley was the first to work at Larrabee's new studio, producing tracks for Michael Jackson's Dangerous "Dangerous (Michael Jackson album)") album. Both of the studios at this location underwent major remodels in 1995–1996, and Larrabee added a large atrium with lounge space in 2000. After selling Larrabee West, Larrabee North became the company headquarters and main location, referred to simply as Larrabee Studios. ### Larrabee East [edit] [...] ## History [edit] ### Larrabee West [edit] The original Larrabee Studio location, named after its location on Larrabee Street in West Hollywood, California was co-founded by singer-songwriter Carole King and her husband, lyricist Gerry Goffin in the 1960s. In 1969, Jackie Mills, a jazz drummer, record producer, and co-founder of the short-lived Ava Records, purchased the studio together with his wife Dolores Kaninger. The couple operated the studio until 1985, when they sold it to their son Kevin Mills. This original Larrabee Studio location became referred to as Larrabee West after the establishment of Larrabee North in 1991, and remained in operation until 2003. ### Larrabee North [edit]

• Intel's Larabee Legacy - by Babbage - The Chip Letter

  I have great reverence for Intel and its extraordinary history, and I would never count them out (the resurrection of a clinically-dead AMD shows what is possible!), but I also won’t be integrating with any of their technology until their acute cultural issues are addressed. With regard to these cultural issues (and his other strengths aside), Pat Gelsinger was indisputably wrong for Intel. The world has moved on since Gelsinger’s departure and in Lip-Bu Tan has a very different leader, but it turns out that Larabee arguably casts a long shadow over Intel’s history and decline over the last decade and a half. Share But what was Larabee? In short, it was an attempt to build a graphics architecture based on Intel’s x86 CPU designs. [...] … Larrabee was never primarily a graphics card. If Intel had wanted a kick-ass graphics card, they already had a very good graphics team begging to be allowed to build a nice big fat hot discrete GPU - and the Gen architecture is such that they'd build a great one, too. But Intel management didn't want one, and still doesn't. But if we were going to build Larrabee anyway, they wanted us to cover that market as well. But killing products has consequences. Intel really needed a discrete GPU to compete with Nvidia and AMD. The end of Larabee meant it was left without one. And with the benefit of hindsight, the failure was even more damaging than was realised at the time. Intel had no competitive GPU that could participate in AI boom of the 2020s. #### Intel’s Trust Issues [...] Leaving aside whether an x86 based GPU was a good idea in the first place, the project itself has been widely recognised as a disaster. This post from 2009 lays out lots of the gory detail: … as the time went by, we received bits and pieces with more worrying content. Back in 2007, when Larrabee started to take physical shape, we heard some very worrying statements coming from the people that were coming and going from the team. Most worrisome was the issue with the memory controller – “people involved in designing high performance memory controllers don’t even understand the basic concepts of pipelining and they don’t understand how to read a memory spec. It is completely ridiculous.” With a 2009 assessment of how much Larabee cost
