Here's your #HPC update for the week ending April 24: @Google launches TPU 8t and 8i; Google cranks the scaling bar with #Virgo network; and a new GPU from @boltgraphics promises lots of #FP64. @HPCwire

*We taped out our TSMC 12 nm test chip!!!* I’m really proud of the @boltgraphics team - we are announcing the successful tapeout of our TSMC 12 nm test chip, which includes key parts of the Zeus GPU we are building! We are on track to achieve our performance and efficiency targets, as well as our customer target to reduce TCO by up to 17x. We’ve been working with large enterprises, startups, research institutions, individual developers and end users for years now, and they’ve been providing positive feedback on our hardware and software! We aim to enter mass production in Q4 2027, right in time for the holidays! If you’re not already a part of this amazing journey, sign up on our website to get early access to Zeus or apply for a job! prnewswire.com/news-releases…

Yesterday at @playgroundsfest we shared Singularity in a pre-premiere screening. So cool to watch the film together with fellow artists! Official premiere and online release dates are coming soon. #b3d

🚀 A new way of thinking about GPUs takes the SIGGRAPH 2026 mainstage. Bolt Graphics presents “Building a GPU for the Future of Computer Graphics,” exploring a shift in how we approach path tracing and simulation. At the center is Zeus, a next-gen architecture designed for real-time path tracing, large-scale simulation, and compute-heavy workloads. Register now to join Darwesh Singh and see what this means for creators, researchers, and engineers: s2026.siggraph.org/program/k…

Simulation is a super powerful R&D tool. Think about robotics: why break real robots when you can test via simulation? Iterate faster. Shift left. But for the average engineer, simulation is too slow and too expensive. It doesn't have to be that way though. Watching @boltgraphics here
We are solving this problem in our chip. We have made accurate electromagnetic simulations 300x faster. This is going to massively accelerate photonic chips design, optics, RF sensors/emitters, metamaterials, metastructures, and more

We’re hiring lots of graphics programmers, please apply at bolt.graphics/careers under the Software Engineer rec ! We offer competitive pay, WFH for remote, and 100% employer covered health benefits, and of course a strong unique mission to build next-generation GPUs for content creation and consumption @boltgraphics
guess who got laid off today! 🫠 i am genuinely so confused and bewildered like, i spent the past week debugging the rivalry system while recovering from pneumonia and just in the past few days i’ve had multiple directors tell me how much they appreciate everything i do

We even made a video about it on YouTube.
Getting a lot of questions about memory bandwidth. The charts below show bandwidth and cache per FP32 core (I.e. cuda core) 2x memory bandwidth per core vs 5090 11x sram cache per core vs 5090 amd is less cache/BW anemic Zeus scales out well, and keeps data on chip more

I wrote a report on the GPU market, covering rendering, gaming, and HPC industries. Some interesting takeaways: - 3+ billion active gamers worldwide - 1+ billion GPUs shipped every year (the majority being smartphones) - 66% of the discrete GPU market has ASPs over $970 - 25-50% of time and money is spent waiting for GPUs to render or perform simulations. Over $1B/yr is spent waiting for your GPU to finish its work. Faster GPUs save time/money. bolt.graphics/overview-of-th…

Yeah, we’re building GPUs, but we also make art to test our software. This time, @mcurt09 cooked 🎨🧑‍🍳🖼️ (Yes, this is a render and not a picture) This is part of our Zeus / Greek mythology theme. A lot more to come creative content-wise!

Creating some fun Greek🇬🇷 architecture and design assets to showcase the new Glowstick render engine from @boltgraphics Check out the modelling timelapse of this classic Klismos chair and stay tuned for more behind the scenes goodies 🏛️

When you do it right these (tiny) bad boys (75W) beats H100, B200, Threadrippers in performance and efficiency We use these to beat our competitors and stress test our software before we spend $10s of millions taping out chips We design hardware only using first principles, and *unlike our competitors* we ask our users what they want. Then we go make it fast, reliable, efficient, and simple This is how we win 🏆 🚀

We made an FDTD solver that is: - about as fast as an H100 (!!!) or Threadripper 5995WX (and we’re getting faster every week) 🏎️ 🚀 - 1/4 the power vs the Threadripper!! 🔋 - IEEE-754 FP64 across the entire pipe - INTERACTIVE VIEWER that shows the field of your choice as the simulation progresses 📺 - FREE for early access and when you buy Zeus GPU (perpetual license)! - per timestep field output that isn’t slow as shit - 2D NOW in early access and full 3D coming soon - GDS input NOW and STL coming soon Here’s the full video with more info + the direct comparison to meep: youtu.be/M2uGJa6u030?si=O69K… Link to the documentation coming Friday! Reach out for access to Apollo, we want to test this crazy thing on more designs. We’ll be testing all of the meep samples and more over the next few weeks! This is running on an FPGA. In the ASIC we’re taping out soon, we’re scaling this up and projecting 300x over GB200, and much larger memory capacity (more cells!!) that we can’t get on the FPGA

This little beast peaks at 120W and outperforms an H100 (240W) and Threadripper 5995WX (450W) in FDTD And much less expensive, and silent.
Fun times at IMS last week in SF! We demonstrated Apollo, our electromagnetic simulator (2D/3D FDTD solver). We matched the speed of an H100 with almost 1/3 the power in FPGA. Want to simulate your RF/photonic chips, UAVs, or something completely new? We can do it faster, more accurately, with less power, and with less cost (the software is free, unlike our commercial competitors). Zeus is still benchmarking at 300x over B200 in FDTD 🚀🚀🚀

Building GPUs that are faster+cheaper+more efficient than Nvidia in gaming, film rendering, HPC, and inference. We can share benchmarks and demos. bolt.graphics
