AMD ZEN Engineering Sample Specs Leaked

Published by


New details on AMD Zen based CPUs have surfaced, the information is based on engineering samples that AMD already has been circulating. Blogger Dresdenboy AMD has confirmed the information making the reliability of the information plausible.

The engineering samples currently are set at revision A0. The user who spread the details talks about four chips with 4, 8, 24 and 32 of cores. The first two SKUs would be for the AM4-socket, while the last two were intended for servers.

  • 4 variants of ES Zen are available at the moment:
  • AM4 8 cores with 95W TDP
  • AM4 4 cores with 65W TDP
  • SP3 24 cores with 150W TDP
  • SP3 32 cores with 180W TDP

The two AM4 chips are quad-core and octa-core with 8 and 16 threads. The quad-core would be get 2 MB L2 cache and 8MB L3 cache, while the octa-core would get  double that amount. Both engineering samples currently run a clock speed of 2.8 GHz, with a maximum boost up to 3.2 GHz. The TDP of the two would be 65 watts for the chip with four cores and 95 watts for the octa-core. In idle the clock speed can throttle down back to 550 MHz with an amzing power consumption 2.5 and 5 watts idle power.

For servers there is the SP3 platform. The leaker has details on a 24-core and 32-core chip. The boost clock speed is at the 24-core 2.75 GHz and the 32-core 2.9 GHz. The idle-clock rate is 400 MHz here with even lower. The TDP of the two is 150 and 180 watts respectively. These chips have two 64 MB L3 cache, with the 24-core 12 MB of L2 cache and get the 32-core 16MB. This suggests that every Zen-core inherits 512KB of L2 cache, while each set of four cores gets 8MB L3 cache. This corresponds to a previously surfaced die-shot of a core-Zen.

The information has been confirmed by Dresdenboy, he has a good track record, but it remains a rumor/leak and as such a grain of salt is something you should always take this info with.
