Intel have debut some new GPU-adjacent designs on the International Solid-State Circuits Conference (or ISSCC for brief), however earlier than you get too excited this announcement isn’t the results of Intel’s new graphics division condensing years of labor into only some months, it’s purely an unrelated analysis undertaking on GPU energy effectivity.
Intel have loads of competitors for high-end GPUs. Here are the best graphics cards round.
Intel are anticipated to in the future put collectively some type of discrete GPU since they acquired AMD’s high GPU-mind. Raja Koduri could have joined Intel to go up the newly-formed Core and Visual Computing Group, however even for an skilled GPU architect, three months on the job could also be asking just a little a lot to prototype a complete functioning GPU structure.
The announcement from ISSCC got here by way of PCWatch, who rightfully reported that this prototype GPU isn’t going to be in the marketplace as a standalone product anytime quickly. The design is constructed upon the 14nm fabrication course of, and options largely the identical expertise that Intel presently utilised inside their present iGPU designs. At 1.2V, the GPU would attain a blistering velocity of… 400MHz.
The design options 18 of Intel’s Execution Units (EUs), and totals simply over 1.5 billion transistors in whole. For just a little reference, AMD’s Vega 64 has 12.5 billion transistors and Nvidia’s GTX 1080 Ti 12 billion of the little 16nm suckers.

The chip’s perform, nevertheless, wasn’t to unleash this underwhelming iGPU-fueled graphics energy on the unsuspecting world. No, it was really meant to point out higher granular voltage management and energy effectivity utilized to a GPU, resulting in higher energy effectivity for their very own iGPU chips.
“Last week at ISSCC, Intel Labs presented a research paper exploring new circuit techniques optimizes for power management”, Intel say in an announcement to Liliputing, “The team used an existing Intel integrated GPU architecture (Gen 9 GPU) as a proof of concept for these circuit techniques. This is a test vehicle only, not a future product. While we intend to compete in graphics products in the future, this research paper is unrelated. Our goal with this research is to explore possible, future circuit techniques that may improve the power and performance of Intel products.”
Intel nonetheless have a protracted method to go along with any discrete GPU merchandise, and that’s most likely a very good factor – we don’t need one other Larrabee, in any case. The GPU design printed at ISSCC is fairly low-power and low-performance, and I don’t find out about you, however I’d hope that when Intel do launch a discrete graphics product it packs just a little extra punch than this.
When Intel do announce their very own discrete GPU – nevertheless far-off which may be – I think about they’d see match to organise their very own occasion to take action, moderately than let slip their whole design at an electrical engineering convention in San Fran.
