Broadwell (microarchitecture)
From Wikipedia, the free encyclopedia
| Predecessor | Haswell |
|---|---|
| Successor | Skylake |
In keeping with Intel's tick-tock principle, the 14 nm shrink of Haswell is due out the year after the refresh of the introduction of the microarchitecture and will be codenamed Broadwell.[1][2] Broadwell will adopt the Multi-Chip Package (MCP) design. Broadwell should be widely available in 2015.[3]
Broadwell will introduce some instruction set architecture extensions:[4][5]
- ADOX/ADCX/MULX for improving performance of arbitrary-precision integer operations[6]
- RDSEED to generate 16-, 32- or 64-bit random numbers according to NIST SP 800-90B and 800-90C[7]
- PREFETCHW instruction[7]
Broadwell is expected to launch in three major forms:[8]
(1) Desktop version (LGA1150 socket): Broadwell-D
(2) Mobile/laptop version (PGA socket): Broadwell-M
(3) BGA version:
- (a) 35 W and 55 W TDP classes: Broadwell-H (For "all-in-one" systems, Mini-ITX form factor motherboards, and other small footprint formats.)
- (b) Less than 15 W TDP class (SoC): Broadwell-U (For Intel's Ultrabook and NUC platforms.)
- (c) Less than 10 W TDP class (SoC): Broadwell-Y (For tablets and certain Ultrabook-class implementations.)
