Intel Gets Graphic with Chip Delay – Bits Blog –

Intel’s executives were quite brash when talking about Larrabee even though most of its public appearances were made on PowerPoint slides. They said that Larrabee would roar onto the scene and outperform competing products.

And so now finally the NY Times nails the coffin shut on Intel’s Larrabee saga. To refresh your memory this is the second attempt by Intel to create a graphics processor. The first failed attempt was some years ago in the late 1990s when 3dfx (bought by nVidia) was tearing up the charts with their Voodoo 1 and Voodoo 2 PCI-based 3D accelerator cards. The age of Quake, Quake 2 were upon us and everyone wanted smoother frame rates. Intel wanted to show its prowess in the design of a low cost graphics card running on the brand new AGP slot which Intel had just invented (remember AGP?). What turned out was a similar set of delays and poor performance as engineering samples came out of the development labs. Given the torrid pace of products released by nVidia and eventually ATI, Intel couldn’t keep up. Their benchmark was surpassed by the time their graphics card saw the light of day, and they couldn’t give them away. (see Wikipedia: Intel  i740)

Intel i740 AGP graphics card
1998 saw the failure of the Intel i740 AGP graphics card

The Intel740, or i740, is a graphics processing unit using an AGP interface released by Intel in 1998. Intel was hoping to use the i740 to popularize the AGP port, while most graphics vendors were still using PCI. Released with enormous fanfare, the i740 proved to have disappointing real-world performance, and sank from view after only a few months on the market

Enter Larrabee, a whole new ball game at Intel, right?! The trend toward larger numbers of parallel processors on GPUs from nVidia and ATI/AMD led Intel to believe they might leverage some of their production lines to make a graphics card again. But this time it was different, nVidia had moved from single purpose GPUs to General Purpose GPUs in order to create a secondary market using their cards as compute intensive co-processor cards. They called it CUDA and provided a few development tools at the early stages. Intel latched onto this idea of the General Purpose GPU and decided they could do better. What’s more general purpose than an Intel x86 processor right? And what if you could provided the libraries and Hardware Abstraction Layer that could turn a larger number of processor cores into something that looked and smelled like a GPU?

For Intel it seemed like a win/win/win everybody wins. The manufacturing lines using older design rules at the 45nm size could be utilized for production, making the graphics card pure profit. They could put 32 processors on a card and program them to do multi duties for the OS (graphics for games, co-processor for transcoding videos to MP4). But each time they did a demo a product white paper and demo at a trade show it became obvious the timeline and schedule was slipping. They had benchmarks to show, great claims to make, future projections of performance to declare. Roadmaps were the order of the day. But just last week rumors started to set in.

Similar to the graphics card foray of the past Intel couldn’t beat it’s time to market demons. The Larrabee project was going to be so late and still was using 45nm manufacturing design rules. Given Intel’s top of the line production lines moved to 32nm this year, and nVidia and AMD are doing design process shrinks on their current products, Intel was at a disadvantage. Rather than scrap the thing and lose face again, they decided to recover somewhat and put Larrabee out there as a free software/hardware development kit and see if that was enough to get people to bite. I don’t know what if any benefit any development on this platform would bring. It would rank right up there with the Itanium and i740 as hugely promoted dead-end products with zero to negative market share. Big Fail – Do Not Want.
