Intel gen-12 Core HX puts ‘desktop’ processors in laptops • The Register


Intel Vision Intel said it put “desktop” silicon in a mobile package to deliver its fastest 12andgeneration Core laptop processors at the moment.

The chipmaker unveiled the seven 12andchips for first-generation Core HX laptops at Intel’s Vision event on Tuesday, where the company also revealed AI chips set to challenge Nvidia and a roadmap for its all-new line of CPU processing units. infrastructure for data centers.

These latest Core chips are expected to power more than 10 laptops released later this year from Dell, HP, Lenovo and other PC makers, and they’re based on the same Alder Lake hybrid architecture that debuted with the 12 d. ‘Intel.and-gen Core S-Series for desktop PC last fall.

Specifications and features

What makes the 12and-gen HX different from other Alder Lake laptop processors released earlier this year is that they are supposed to be more powerful and come with features aimed at power users such as PCIe 5.0 connectivity, code memory error correction and RAID support. Like other processors in the wider 12and-gen, some models include Intel’s vPro enterprise-grade management and security features.

As for other features, the processors support overclocking, which includes the ability to overclock the memory as well as the efficient cores of the processors. The processors also support up to 128GB of DDR4-3200 and DDR5-4800 memory as well as Thunderbolt 4 interfaces for up to two controllers.

The HX chips consist of a total of seven Core i5, i7 and i9 models, and they feature up to 16 processor cores – divided between eight performance cores and eight efficient cores – a maximum turbo frequency of 5 GHz, a 2.3 GHz base frequency and a 30 MB L3 cache. For integrated graphics, the chips feature a maximum graphics unit frequency of 1.55 GHz, and all but one model pack 32 graphics units. execution.

But in exchange for high performance and advanced features, processors require a lot of power. The base power of all the latest chips is 55 watts, and it can go up to 157 watts to extract every ounce of performance from the silicon. This is higher than the power envelope for the regular 12and-gen H-Series processors, which have a base power of 45 watts and a turbo power of 115 watts.

Performance claims

Intel said architectural improvements allow its latest flagship mobile chip, the Core i9-12900HX, to deliver 17% better single-threaded performance and 64% better multi-threaded performance compared to the year’s Core i9-11980HK. latest, based on internal testing using the SPECint_rate_base2017 benchmarks.

The semiconductor giant also said it saw performance gains in specific applications, with 81% better performance for 3D rendering in Blender, 28% better performance for creating models in Autodesk Revit, 21% better performance for simulation in Autodesk Inventor and 12% better performance. for design in Autodesk AutoCAD.

Intel has claimed that the Core i9-12900HX is faster than the best notebook silicon from AMD and Apple. Specific benchmark figures were not provided for the tests it ran, although Intel shared various performance comparisons [PDF] which places its flagship chip above Apple’s M1 Max and AMD’s Ryzen 9 6000 H-Series chips in several tests.

However, we note that, for example, the Intel Core i9-12900HX received an Nvidia RTX 3080ti graphics card during its tests, the previous i9-11980HK an RTX 3080 and the AMD Ryzen 9 6900HX was passed along with an RTX 3060. This doesn’t seem like a direct comparison to us, so take all of this benchmarking with an appropriate grain of salt.
