Examples of ASICs/NPUs Used in Popular Hardware

7600 EX+ line cards use the Ezcip NP3C unit (supposedly a Cisco customised version of the NP3?) which has the Santa Cruz ASIC, as do the ASR9000 Trident line cards as they are beefed up EX+ cards (the first gen ASR9001 used a built in Trident card so they are also using NP3C units). They also use the NetLogic Microsystems NETL7 unit for layer 7 processing at 10Gbps.

The Ezchip/Mellanox NP4 units support 100Gbps: http://www.mellanox.com/related-docs/prod_npu/PB_NP-4.pdf

The BCM88670 (Jericho) is what powers the Cisco NCS5502/08 devices. The processor is linerate above around 100 bytes per packet without external TCAM, supports 256K IPv4 / 64K IPv6 FIB entries (or mixed amounts).  These chips are being used for high scale 100G, the initial NCS5508 linecard is a 36x100G QSFP28 card.

From BRKSDN-2063:
Broadcom DNX-based NPUs:
NCS5501 uses a single Broadcom Qumran-MX NPU with no off-chip TCAM but off-chip packet memory (the SE- version has both off-chip). The NSC5502 uses 8x Broadcom Jericho NPUs with no off-chip TCAM but off-chip packet memory (the SE- version has both off-chip). The NCS5508 is a modular chassis based system with all line cards using varying amounts of Broadcom Jericho NPUs.

NSC5001 and NCS5002 both use a single Broadcom Trident II+ NPU which doesn't use offchip TCAM or packet memory.

NCS5011 uses a single Broadcom Tomahawk NPU which doesn't use offchip TCAM or packet memory.

 

Broadcom TridenII

[Extreme] x670 is trident2; x670-G2 is trident2+. There is documentation to
suggest that control word is supported on the juniper qfx5100 and the
cisco ncs500x, both of which also use the t2+ chipset, but documentation
occasionally diverges from reality, so this shouldn't be taken as hard
evidence one way or another.

Arista 7500R is based on Broadcom's "Jericho".
