Intel 12th Gen Core AlderLake Mobile (i7-12700H) Review & Benchmarks – big/LITTLE Performance

Intel Logo

What is “AlderLake”? It is the “next-generation” (12th) Core architecture – replacing the short-lived “RocketLake” (RKL) that finally replaced the many, many “Skylake” (SKL) derivative architectures (6th-10th). It is the 1st mainstream “hybrid” arch – i.e. combining big/P(erformant) “Core” cores with LITTLE/E(fficient) “Atom” cores in a single package. While in … Read more…

Microsoft Surface Pro X – Windows Arm64 on Microsoft SQ2 Performance

What is “Surface Pro X”? It is Microsoft’s Arm64 range of Surface tablets – rather than the standard Intel x86 Surface Pro range (e.g. 3, 6, 8, etc.). After the disastrous Windows RT ARM tablets, Microsoft is trying again – this time with full 64-bit Arm64 Windows 10/11, good memory … Read more…

Windows Arm64 on Qualcomm Snapdragon 7c Performance

What is “Qualcomm’s Snapdragon”? It is a family of ARM processors/SoCs – analogous to the Intel’s “Core” in the x86 world. It now spans 8 series going back years and is used for everything from laptops, tablets, phones and even smart-watches! Unlike other ARM SoC manufacturers (Samsung, Huawei, MediaTek, etc.), … Read more…

Windows 10 Arm64 WoW – x86 Emulation Performance

What is “WoW”? “WoW” stands for “Windows-on-Windows” is the compatibility/emulation layer that allows the execution of different architecture applications on the same version of Windows. Originally (in the days of Windows NT) it allowed running 16-bit x86 legacy applications on 32-bit x86 Windows NT. Today, with 64-bit Windows, it allows … Read more…

Raspberry Pi 4B Review: Windows Arm64 on Broadcom BCM2711

What is “Raspberry Pi 4B”? It is the 4th generation of the Raspberry Pi series of single-board computers (SBC) that can be consider to have single-handedly restarted the enthusiast computer revolution of the 1980s. Selling millions of units per year, it is the best selling UK computer and used far … Read more…

Raspberry Pi 3B+ Review: Windows Arm64 on Broadcom BCM2837

What is “Raspberry Pi 3B(+)”? It is the 3th generation of the Raspberry Pi series of single-board computers (SBC) that can be consider to have single-handedly restarted the enthusiast computer revolution of the 1980s. Selling millions of units per year, it is the best selling UK computer and used far … Read more…

Mythical Intel 12th Gen Core AlderLake 40C/40T E-Cores (i11-12911E) – AVX2 Extrapolated Performance ;)

CPU Arithmetic Benchmark

What is this “AlderLake-E”? After considering whether the recently released AlderLake (ADL) would have been better with 10 big/P(erformance) Cores and AVX512 rather than hybrid – someone asked why not the other way round? Why not just use LITTLE/E(fficient) Atom cores and no big/P cores? Note that Intel had such … Read more…

Mythical Intel 12th Gen Core AlderLake 10C/20T big/P Cores (i11-12999X) – AVX512 Extrapolated Performance ;)

CPU Neural Networks Benchmark

What is this “AlderLake-X”? ADL has now been launched – with AVX512 disabled: but, for the moment, it is possible to enable AVX512 on some boards; at least until the next microcode update. Some users have managed to benchmark ADL with AVX512 enabled (only big/P Cores enabled, LITTLE/E Atom cores … Read more…

big/Performance Core Performance Analysis (Intel 12th Gen Core AlderLake (i9-12900K))

What is “AlderLake”? It is the “next-generation” (12th) Core architecture – replacing the short-lived “RocketLake” (RKL) that finally replaced the many, many “Skylake” (SKL) derivative architectures (6th-10th).

Intel 11th Gen Core RocketLake – Cache & Memory Performance (2x DDR4-3200)

What is “RocketLake”? It is the desktop/workstation version of the true “next generation” Core (gen 10+) architecture – finally replacing the ageing “Skylake (SKL)” arch and its many derivatives that are still with us (“CometLake (CML)”, etc.). It is a combination of the “IceLake (ICL)” CPU cores launched about a … Read more…

Intel 11th Gen Core RocketLake AVX512 Performance Improvement vs AVX2/FMA3

What is AVX512? AVX512 (Advanced Vector eXtensions) is the 512-bit SIMD instruction set that follows from previous 256-bit AVX2/FMA3/AVX instruction set.
