Tenstorrent CEO Jim Keller shared the company’s performance estimates for CPUs based on its proprietary Ascalon processor cores compared to competitors such as AMD’s Zen 5, Amazon’s Graviton 3 and Nvidia’s Grace. . Tenstorrent’s Ascalon is projected to deliver market-leading integer performance per watt, but much of the attention has been focused on Tenstorrent’s prediction that AMD’s Zen 5 will be the performance champion for raw integer throughput. That’s what I expect. In fact, Keller predicts that AMD’s Zen 5 will be 30% faster than the current generation Zen 4 in integer workloads.
Jim Keller share Tenstorrent’s own-designed 8-wide out-of-order execution Ascalon RISC-V core performance projections against potential competitors in the SPEC CPU 2017 INT Rate benchmark measuring integer performance. The company expects Ascalon 1.9 SPEC2K17INT/GHz to score 7.03 points and Ascalon 2.2 SPEC2K17INT/GHz to score 8.14 points.
The performance Tenstorrent expects from its own CPU was revealed at the Nerds Talking to Nerds About RISC-V event held in India, as shown in the slide below.
In our predictions, Tenstorrent’s upcoming CPU cores comfortably outperform Intel’s Sapphire Rapids (7.45 points), Nvidia’s Grace (7.44 points), and AMD’s Zen 4 (6.80 points). Still, AMD’s Zen 5 is projected to hit 8.84 points, making it the outright integer performance champion for 2024-2025.
Tenstorrent’s performance expectations have a big pitfall. They are all predictions, not real or simulated benchmarks, Tentorrent said. tom’s hardwareThat’s why Tenstorrent engineers accurately modeled the performance of their own CPU designs to Predict What AMD can offer next, these are still predictions, not actual benchmark results.
For obvious reasons, this prediction is unlikely to be entirely accurate, but it’s AMD’s Zen 5 performance numbers that get the most attention. But perhaps more importantly, Tenstorrent expects AMD’s Zen 5 to run north of 4.0 GHz, with a TDP of 250W, as opposed to Ascalon, which runs at around 3.80 GHz with a TDP of around 200W. is that
Considering power consumption, processors based on Tenstorrent’s Ascalon microarchitecture (such as the company’s own Aegis chiplet) actually offer excellent integer performance per watt, which is especially important for the types of applications the processor is designed for. It looks like to meet.
