![]() So just how much of that holds true? Not much, apparently. Intel Core i7-12700K Review: Windows 10 vs 11 Intel and Microsoft even promise better performance and efficiency for Alder Lake processors on Windows 11. Conversely, Windows 10 simply recognizes E-cores as lesser capable P-cores-disregarding their performance-per-watt capability for less-demanding workloads. Intel has worked closely with Microsoft to build a scheduler that can recognize the hybrid architecture of Alder Lake processors in Windows 11.Īs a result, Windows 11 has a clearer idea of the P-cores and E-cores-their power and efficiency levels. The OS scheduler then uses this info to decide where each thread goes-either to a performance or an efficiency core. Kind of like a guard in a panopticon prison. It’s a microcontroller built directly inside the CPU, which monitors each thread and the state of each core-and forwards this information to the operating system. Intel Thread DirectorĪnd that’s where the Intel Thread Director comes in. You can easily guess how terrible a gaming session would go if the OS assigned a game’s process requests to E-cores instead of P-cores. AMD’s Ryzen 5000 series absolutely thrashed the 11th Gen Core processors in terms of power efficiency (besides the embarrassing performance dominance), so the use of low performance-per-watt CPU cores is a change born almost out of necessity.īut the problem arises when the operating system cannot properly schedule threads to the ‘P’ and ‘E’ cores. Now, all this sure sounds fantastic for Team Blue. Do note that the P-cores have hyperthreading enabled and can therefore run two threads per core-whereas the E-cores are single-threaded. These penta-core CPUs consisted of one powerful “Sunny Cove” core and four low-power “Tremont” cores-and were designed for ultraportable, foldable, and dual-screen devices.Īccording to Intel, these ‘E’ cores manage 40% better performance at the same power level (or same performance while consuming 40% less power) compared to 6th Gen “Skylake” cores in single-thread performance. But they were short-lived and discontinued the very next year of the release. Technically, Intel did experiment with the hybrid core design in 2020 with “ Lakefield”. But x86-based Intel and AMD CPUs have been married to the traditional CPU layout with a single class of high-performance cores for as long as there have been Intel and AMD processors. Such CPU design is pretty common on Arm-based mobile processors. This consists of high-performance ‘P’ cores and high-efficiency ‘E’ cores-based on a new “Golden Cove” and “Gracemont” microarchitecture, respectively. Unlike your typical processor with a single, homogenous CPU design, Alder Lake has a hybrid, heterogeneous core architecture. Let’s start with the belle of the ball-the hybrid architecture. ![]() These are probably not even noticible in game unless measuring, but I see no reason to choose the DX12 option.There’s big.LITTLE hybrid architecture (or “Big-Bigger” as Intel calls it), a new “Intel 7” process node, something called “Thread Director”, and a lot of platform upgrades. So, yeah, on my rig I'm getting expected results with DX12 as posted by others.įramerate is ~10% lower and turn times are ~3.5% higher. Looks like turn time went up by ~3.5% going from DX11 to DX12. Raw output - however - appears to drop about 10% with DX12. So, since I normally play this game with vsync on and set to 60hz, either of these will likely result in the same performance. Quality: Everything set to highest allowable setting in advanced tab. Titan X (Pascal) at 2063Mhz core and 5508Mhz VRAM Sandy-E hexacore with HT enabled for 12 logical cores. Well, if anyone is curious here are mine:
