In a nutshell: Can somebody construct a 3D graphics card from scratch? Dylan Barrie wished to search out out and spent 4 years attempting. The outcome was an entire GPU that may theoretically run older gaming software program on Windows.

Dylan Barrie is a recreation developer and {hardware} hobbyist. Over the final fourteen years of his profession within the recreation trade, Barrie primarily targeted on the software program aspect of graphics rendering. However, he began creating a customized, full-stack GPU 4 years in the past in his spare time.

Barrie stated the method of making a graphics card from the bottom up was hellish, however after 4 years of diligence, he can lastly share his efforts now that the add-in card design is basically accomplished. FuryGPU is a “actual {hardware} GPU” constructed on a Xilinx Zynq UltraScale+ FPGA design. The card makes use of a customized PCB and connects to the host PC by way of a PCIe slot.

FuryGPU can assist {hardware} options equal to a “high-end” graphics card from the mid-Nineties, with a full software program and driver stack for contemporary Windows variations. The GPU can render video games from that decade with real-time, playable body charges. Barrie will ultimately launch {hardware} schematics, software program, and drivers by means of an open-source license.

The {hardware} homebrewer stated he determined to construct a graphics processor from scratch as a result of he did not know the “precise particulars” of how GPUs work. Being “extraordinarily acquainted” with the 3D rendering course of from the software program aspect, Barrie realized that making a GPU could possibly be a doable albeit daunting private challenge.

He spent “numerous hours” studying how FPGA chips work and methods to construct chip designs by means of {hardware} description, verification, and the implementation language SystemVerilog. Designing the schematics for a PCIe graphics card was a “herculean effort,” Barrie stated. Perhaps unsurprisingly, writing Windows drivers was the challenge’s most painful process.

The developer wrote a customized graphics API to speak with the GPU and created Windows kernel drivers for managing the show and audio alerts. The FuryGPU can render Quake – the unique Quake launched in 1996 – at a “strong” 60 frames per second, which might have been a real pleasure for players within the 90s.

Barrie plans to write down extra about his GPU creation journey on his FuryGPU weblog, beginning with the cardboard’s Texture Units. He additionally desires to optimize his customized Quake construct to run a lot sooner.
