Skylake µarch
General Info
ERROR: "atype" is missing!

Skylake (SKL) is Intel's microarchitecture using 14 nm process for mainstream desktops, servers, and mobiles. Skylake became the successor to the short-lived Broadwell which experienced severe delays.

For desktop and mobile, Skylake is branded as 6th Generation Intel Core processors. For server class processors, Intel branded it as Xeon E3 v5, Xeon E5 v5, and Xeon E7 v5.

Process Technology

Main article: Broadwell § Process Technology

Skylake uses the same 14 nm process used for the Broadwell microarchitecture.

Architecture

Overall Skylake builds upon Intel's previous microarchitecture, Broadwell, but includes a more beefed up front end, more optimized execution engine, and numerous number of smaller enhancements. Intel designed Skylake to encompass a wide range of devices and applications with a large emphasis on mobile with models ranging from as low as 4.5 W to as high as 100 W.

Key changes from Broadwell

  • Bus/Interface to Chipset
    • DMI 3.0 (from 2.0)
      • Skylake S and Skylake H cores, connected by 4-lane DMI 3.0
      • Skylake Y and Skylake U cores have chipset in the same package (simplified OPIO)
      • Increases speed from 5.0 GT/s to 8.0 GT/s (~3.93GB/s up from 2GB/s)
      • Limits motherboard trace design to 7 inches max from (down from 8) from the CPU to chipset
  • Front End
    • Larger legacy pipeline delivery (5 µOPs, up from 4)
    • Larger IDQ delivery (6 µOPs, up from 4)
    • 2.28x larger allocation queue (64/thread, up from 28/thread)
    • Improved branch prediction unit
  • Execution Engine
    • Larger re-order buffer (224 entries, up from 192)
    • Larger scheduler (97 entries, up from 64)
      • Larger Integer Register File (180 entries, up from 160)
    • Larger store buffer (56 entries, up from 42)
  • Memory
    • L2$ was changed from 8-way to 4-way set associative
  • TLBs
    • ITLB
      • 4KB page translations was changed from 4-way to 8-way associative
    • STLB
      • 4KB+2M page translations was changed from 6-way to 12-way associative
  • Electrical
    • The fully integrated voltage regulator (FIVR) is moved back to the motherboard
      • Originally intended to be a cost-cutting measure by moving the FIVR on-die as well as making it more efficient, the move resulted in unintentionally making the FIVR the limiting factor when it came to overclocking.

CPU changes

  • Most ALU operations have 4 op/cycle 1 for 8 and 32-bit registers. 64-bit ops are still limited to 3 op/cycle. (16-bit throughput varies per op, can be 4, 3.5 or 2 op/cycle).
  • MOVSX and MOVZX have 4 op/cycle throughput for 16->32 and 32->64 forms, in addition to Haswell's 8->32, 8->64 and 16->64 bit forms.
  • ADC and SBB have throughput of 1 op/cycle, same as Haswell.
  • Vector moves have throughput of 4 op/cycle (move elimination).
  • Not only zeroing vector vpXORxx and vpSUBxx ops, but also vPCMPxxx on the same register, have throughput of 4 op/cycle.
  • Vector ALU ops are often "standardized" to latency of 4. for example, vADDPS and vMULPS used to have L of 3 and 5, now both are 4.
  • Fused multiply-add ops have latency of 4 and throughput of 0.5 op/cycle.
  • Throughput of vADDps, vSUBps, vCMPps, vMAXps, their scalar and double analogs is increased to 2 op/cycle.
  • Throughput of vPSLxx and vPSRxx with immediate (i.e. fixed vector shifts) is increased to 2 op/cycle.
  • Throughput of vANDps, vANDNps, vORps, vXORps, their scalar and double analogs, vPADDx, vPSUBx is increased to 3 op/cycle.
  • vDIVPD, vSQRTPD have approximately twice as good throughput: from 8 to 4 and from 28 to 12 cycles/op.
  • Throughput of some MMX ALU ops (such as PAND mm1, mm2) is decreased to 2 or 1 op/cycle (users are expected to use wider SSE/AVX registers instead).

Graphics

  • Skylake retires VGA support, multi-monitor support for up to 3 displays via HDMI 1.4, DP 1.2, and eDP 1.3 interfaces.
  • Direct X 12
  • OpenCL 2.0
  • OpenGL 4.4
  • Up to 24 EUs GT2 (same as Haswell); 48 EUs for GT3, and up to 72 EUs on Iris Pro Graphics
    • 1,152 GFLOPS

New instructions

Main article: See §Added_instructions for the complete list

Skylake introduced a number of new instructions:

  • SGX - Software Guard Extensions
  • MPX -Memory Protection Extensions
  • AVX-512 - Advanced Vector Extensions 512 (Only on high-end Xeon models (SKX))

"Speed Shift" (new power management)

Intel introduced Speed Shift with Skylake, a new methodology for quickly alternating core frequencies in response to power loads. Intel introduced a new unit called PCU (Package Control Unit) which is effectively a full fledged microcontroller (containing power management logic and firmware) that collects and tracks many internal SoC statistics as well as external power telemetry (e.g. Psys and iMon). PCU is also capable of interfacing with the OS, BIOS, and DPTF. Speed Shift improves the performance of frequency shifting by off-loading the control from the operating system to the PCU.

Speed Shift effectively eliminates the need for the OS to manages the P-states - though it does have the final (unless special exceptions occur such as thermal throttling). Intel calls this "autonomous P-state", allowing Speed Shift to kick in in a matter of just ~1 millisecond (whereas the operating system-based p-states control can be as slow as 30 ms). Speed Shift effectively reduces hitting peak frequency in around ~30 ms from over 100 ms (OS-based implementation as before).

Power of System (Psys)

Psys (Power of System) is a way for the PCU to monitor the performance and the total platform power provided to the chip. The chip uses a number of autonomous algorithms (one for "Low Range" and one for "High Range"). The Low Range algorithm frequency is lowered to conserve energy. Algorithm is capable of overriding the low P state - a state calculated ever millisecond based on the active workload and system characteristics. The High Range algorithm deals with elevating frequency for the benefit of increase performance (at the cost of increase energy/inefficiency). The exact ratio of ΔPower/ΔPerformance ≤ αPreference can be finely controlled via the OS and user preferences.
