First gen QSFP or Popey was 400MHz (1.2GHz if you count multithreading) 40 core, 307M transistors, 20MB SRAM, 90nm lithography. It was tensilica platform (like npower) but Cisco IP. I think 2nd gen upped core count to 64 and frequency to 1.5GHz, changed to 40nm lithography and transistor count to 1.8B. Unsure what came after that. But what is software based and what is hardware based? To me ASR1k is HW based, it's an NPU box in my mind. Not having TCAM does not exclude box from being hardware, if not having TCAM means it's not hardware, then also say Juniper MX, PTX are not hardware, Cisco 8k is not hardware, Jericho2 isn't hardware, modern stuff tends to run off of DRAM, not TCAM. -- ++ytti _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
