Intel Core Ultra 7 255HX “Arrow Lake-HX” tested in Geekbench benchmark

An entry in the Geekbench database provides information on the Intel Core Ultra 7 255HX, a processor from the new “Arrow Lake-HX” series. The test also shows evidence of an NVIDIA graphics card, which may be one of the upcoming RTX 50 laptop GPUs.

Hardware tested in a Clevo laptop

The benchmark comes from a Clevo X580 laptop, which contains both the Intel Core Ultra 7 255HX and an as yet unnamed NVIDIA GPU. Such devices are known for their modular hardware and are often used as a platform for performance tests. The results relate to AI calculations, indicating that the graphics card was tested in a scenario optimized for this purpose. The recorded values of the GPU were 6500 points in single-precision calculations and 15760 points in half-precision calculations. These numbers may indicate an entry-level model of the RTX-50 series, but neither the exact GPU configuration nor the name of the card was given in the test results.

Technical details of the Core Ultra 7 255HX

The Core Ultra 7 255HX is part of the “Arrow Lake-HX” series and has a total of 20 cores. These are made up of 8 cores for computing-intensive tasks (“performance cores”) and 12 cores for energy-saving processes (“efficiency cores”). The base clock of the processor is 2.4 GHz. Under load, the performance cores can accelerate to up to 5.2 GHz, while the efficiency cores reach a maximum of 4.5 GHz, and an integrated graphics unit (iGPU) with 64 so-called execution units (EUs) is also installed, which runs at a clock rate of up to 1.9 GHz. This unit could perform basic graphics functions, but is not intended for demanding applications.

Overview of the “Arrow Lake-HX” series

The “Arrow Lake-HX” series comprises various models with different performance specifications. In addition to the Core Ultra 7 255HX, there will also be a version called Core Ultra 7 265HX, which offers slightly higher clock rates. Other models in the series are the more powerful Core Ultra 9 275HX and 285HX with 24 cores as well as the entry-level Core Ultra 5 245HX and 235HX with 14 cores each.

First indications, no conclusive statements

The results from the Geekbench benchmarks provide an initial indication of the specifications of the new hardware. Particularly with regard to the Core Ultra 7 255HX, the data shows a model with a broad core distribution and solid clock rates. Whether the actual performance meets expectations, however, will only become clear in practical tests. The tested NVIDIA GPU also remains a mystery for the time being. Based on the results shown, it is possible that it is a model in the lower performance segment, although further details on this series remain to be seen.
