AMD’s Zen 6 EPYC Venice Pictured as a 256-Core Monster, Massive Twin I/O Dies & First 2nm HPC Chip To Enter Volume Ramp - Wccftech

AMD has showcased its next-generation EPYC Venice CPU at the Advancing AI event, featuring a phenomenal core count of 256 based on Zen 6. For the next stream of data centers, CPUs are going to play a much more important role than GPUs due to the rise in Agentic AI & RL workflows. As such, all CPU vendors are releasing brand new chips that unleash the best capabilities for these workloads while leading the charts against the competition. At Advancing AI 2026, AMD has confirmed to launch its EPYC Venice CPUs based on the Zen 6 core architecture. But while there are still a few hours left in the official presentation, the company has set banners across the Moscone Center West in San Francisco, US. One of these banners featured a very peculiar-looking chip as spotted by Computerbase, and it turns out to be none other than the flagship 256-core EPYC champion. AMD is leveraging its brand new Zen 6 core architecture that will be used on its 6th Gen EPYC CPUs, codenamed Venice. AMD's EPYC Venice chips are the first HPC product to enter volume production on TSMC's 2nm process technology, and their readiness for Helios AI racks proves that AMD will always deliver the best of the best for its high-performance customers.

AMD's 6th Gen EPYC Venice CPUs were teased earlier this year at CES, offering up to 256 cores and 512 threads with eight massive compute dies and two even larger I/O dies. You can also see that each of the eight massive CCDs features a total of 32 cores, sliced into two 16-core complexes. The IO chips in the middle look massive in size, with lots of controllers such as PCIe 6.0, UCIe, DDR5, and more. const bizdev_mid_desktop_json = ''; const bizdev_mid_desktop_creatives = JSON.parse(bizdev_mid_desktop_json); const bizdev_mid_desktop_random = Math.floor(Math.random() * bizdev_mid_desktop_creatives.length); const bizdev_mid_desktop_current = bizdev_mid_desktop_creatives; document.getElementById('bizdev_mid_desktop_link').href = bizdev_mid_desktop_current; document.getElementById('bizdev_mid_desktop_image').src = bizdev_mid_desktop_current; const bizdev_mid_desktop_image_url = bizdev_mid_desktop_current; const bizdev_mid_desktop_image_filename = bizdev_mid_desktop_image_url.split('/').pop(); document.getElementById('bizdev_mid_desktop_wrap').setAttribute('data-key', bizdev_mid_desktop_image_filename); For this chip, AMD has promised over 70% performance & efficiency improvement with its EPYC Venice CPUs, with a >30% increase in thread density. Once again, the requirement for high-performance CPUs has risen tenfold with Agentic AI workloads. And competitors are firing across all cylinders with CPUs that are optimized around agents. Just like GPUs, NVIDIA is AMD's primary competitor in this space, which is leveraging Vera CPUs based on its custom Arm IP to power the Vera Rubin NVL72 racks. AMD's Helios AI racks powered by Zen 6 EPYC chips not only offer more cores, but faster performance and improved single-core capabilities, which is important for sustained throughput. In early benchmarks, AMD has shown that not only do its 5th Gen Turin "Zen 5" CPUs lead against Vera, but the 6th Gen Venice "Zen 6" chips lead massively, driving more performance & offering better TCOs at a similar power scale.
