![]() Until then, I'm not holding my breath for any of their claims.I expect someone will manage to run independent benchmarks on them, but I doubt Nvidia will be sending around review samples - or even giving reviewers free access to their cloud platform. Kamen Rider Blade said:I'll wait till Phoronix, Level1Techs, ServeTheHome, or Chips and Cheese gets ahold of these and benchmarks them. However, Nvidia CEO Jensen Huang recently told us in March that the Grace CPU Superchip is currently in production, so OEM systems will likely launch in the second half of this year. ![]() Initially set to launch in the first half of 2023, the Grace CPU Superchip had suffered a setback. In a dual-processor platform the AMD and Intel chips have the potential to pull up to 720W and 700W, respectively. The default TDP for the EPYC 9654 and Intel Platinum 8480+ is 360W and 350W, respectively. ![]() To put the numbers into perspective, the Grace CPU Superchip has a peak power draw of 500W for the package composed of the two processors and the LPDDR5X memory. Nvidia's charts show the Grace CPU Superchip with up to 2.5X better power efficiency than the competition in a 5 MW data center environment - it was close to 2X more efficient than the AMD EPYC 9654, while the Xeon Platinum 8480+ was the least power-efficient of the trio. The Grace CPU Superchip's strong suit lies in the chip's power efficiency. The AMD chip was up to 30% faster in CFD OpenFOAM and tied with its Xeon rival in Graph Analytics GapBS BFS. The EPYC 9654 outperformed the Xeon Platinum 8480+ with a similar 40% margin in the majority of the workloads. ^ "Qualcomm Snapdragon 8 Gen 1 Mobile Platform | Latest 5G Snapdragon Processor | Qualcomm".^ "Snapdragon 7+ Gen 2 Mobile Platform".^ "Summit Dimensity9000| Latest 5G Snapdragon Processor | Qualcomm"."Arm Announces Mobile Armv9 CPU Microarchitectures: Cortex-X2, Cortex-A710 & Cortex-A510". ^ "Arm Launches Its New Flagship Performance Armv9 Core: Cortex-X2".^ "Arm Total Compute solutions powering decade of compute - Architectures and Processors blog - Arm Community blogs - Arm Community".Arm | The Architecture for the Digital World.
