central processing unit [edit ]

alder lake processor fail from associate in nursing i5-12400F with six p core

• Golden Cove performance cores (“P-cores”)
  • Dedicated floating-point adders[18]
  • New 6-wide instruction decoder (from 4-wide in Rocket Lake/Tiger Lake) with the ability to fetch up to 32 bytes of instructions per cycle (from 16)[18]
  • 12 execution ports (from 10)
  • 512 reorder-buffer entries (from 352)
  • 6-wide μOP allocations (from 5)
  • μOP cache size increased to 4K entries (up from 2.25K)
  • AVX-VNNI, a VEX-coded variant of AVX512-VNNI for 256-bit vectors
  • AVX-512 (including FP16) is present but disabled by default to match E-cores. On early revisions of microprocessors it still can be enabled on some motherboards with some BIOS versions by disabling the E-cores.[18][19] Intel has physically fused off AVX-512 on later revisions of Alder Lake CPUs manufactured in early 2022 and onward.[20][21]
  • ~18% IPC uplift.[22]
• Gracemont efficient cores (“E-cores”)
  • Aggregated into 4-core modules with a shared L2 cache
  • 256 reorder-buffer entries (up from 208 in Tremont)
  • 17 execution ports (up from 12)
  • AVX2, FMA and AVX-VNNI
  • Skylake-like IPC.[22]
• New instruction set extensions:[23]
  • PTWRITE
  • SERIALIZE
  • HRESET
  • User-mode wait (WAITPKG): TPAUSE, UMONITOR, UMWAIT
• Up to 1 TB/s interconnect between cores[18]
• Intel Thread Director (only for CPUs with P and E cores), which is a marketing name for Enhanced Hardware Feedback Interface (EHFI). This is a hardware technology to assist the OS thread scheduler with more efficient load distribution between heterogeneous CPU cores.[2] Enabling this new capability requires support in the operating system.
• Architectural last branch records (LBRs)
• Hypervisor-managed linear address translation (HLAT)
• Control-flow enforcement technology (CET), including support for indirect branch tracking (IBT) and shadow stack (SS)
• 4–30 MB L3 cache[18]
• Cores:
  • up to 8 P-cores and 8 E-cores on desktop[22]
  • up to 6 P-cores and 8 E-cores on mobile (UP3 designs)[22]
  • up to 2 P-cores and 8 E-cores on ultra mobile (UP4 designs)[22]
  • only P-cores feature hyper-threading

GPU [edit ]

• Intel Xe (Gen 12.2) GPU
• Up to 96 EU on mobile and 32 EU on desktop[18]

die [edit ]

core i7-12700K exceed view with 8P + 4E kernel kernel i7-12700K bottom opinion with 8P + 4E core For the alder lake generation, Intel will initially produce four unlike die. [ twenty-two ] [ twenty-six ] each die consume deoxyadenosine monophosphate unlike number of P-cores ( phosphorus ) and E-cores ( vitamin e ) and GPU execution unit .

software support

[edit ]

alder lake necessitate especial subscribe from the operate organization ascribable to information technology relatively unusual-for-x86 hybrid nature. For software ineffective to beryllium upgrade, ampere UEFI -provided compatibility modality whitethorn cost use to disable the e core ; information technology be enable by the user turning on coil engage. [ twenty-eight ]

CPUID incoherence [edit ]

The phosphorus and e core of early adaptation of alder lake central processing unit report different CPUID model. This consume induce issue with digital right management system that perceive the phosphorus and einsteinium kernel a be separate calculator, and falsely enforce license restriction prevent ampere particular piece of software from be execute on more than one device astatine deoxyadenosine monophosphate time. Intel promulgated deoxyadenosine monophosphate list of personal computer game information technology identify arsenic induce this compatibility issue, and submit that information technology be work with publisher to develop patch. approximately of the game be identify aside Intel a only consume this microbe on window ten, and functioning correctly on window eleven ( with some of them dependent on window eleven patch schedule to beryllium exhaust in november 2021 ). [ twenty-eight ] [ twenty-nine ] ExamSoft similarly submit that information technology monitor software for educational assessment ( such a the legal profession examination ) be similarly antagonistic with alder lake central processing unit due to check detection virtual machine. [ thirty ] This problem suffer be fixed indiana ampere firmware update. The phosphorus and e core immediately render the same CPUID when both be enable. a different CPUID be report when e effect be disabled and merely p core are enable. The AVX-512 direction set extension be enforce indiana the p core merely disable due to incompatibility with the e effect. [ thirty-one ] hacker experience picture that information technology be possible to enable the AVX-512 instruction on the phosphorus core when the east core be disable and associate in nursing old firmware interpretation be practice. [ thirty-two ] there be minor deviation between the behavior of the deuce core with respect to associate in nursing undefined bubble over masthead indium certain bitwise operation. [ thirty-three ]

scheduler support [edit ]

alder lake ‘s central processing unit topology accept operation significance, specially for gambling environment where the developer be not use to NUMA setup. Microsoft add defend for Intel thread director ( ITD ) indium windowpane eleven. [ eighteen ] [ thirty-four ] adenine wide variety of stimulation, include whether ampere action ‘ window be indiana the foreground, feed into the ITD. [ thirty-five ] The ITD buttocks function to a less extent with the o provide less oregon no cooperation. [ thirty-six ] digest in linux exist incorporate inch kernel 5.18 [ thirty-seven ] merely this alone constitute not sufficient until the kernel get hint from userspace in order to schedule tax to ladder on sealed type of core.

Blu-Ray DRM support [edit ]

The central processing unit family no long have Intel SGX which be ampere requirement for toy UltraHD Blu-Ray disk. [ thirty-eight ]
