Intel UHD Graphics 16EU (Raptor Lake-HX): Performance of Integrated Graphics in HX Processors

Intel UHD Graphics 16EU (Raptor Lake-HX) is used in some mobile Intel Core HX 13th generation processors. The 16 execution units limit 3D performance. The integrated graphics are sufficient for the Windows interface, video playback, and everyday tasks without a discrete graphics card.

Performance in Real Laptops

In Geekbench 6 Compute, laptops with Intel UHD Graphics 16EU show the following results:

Device Processor Memory iGPU Frequency Geekbench 6
COLORFUL X15 AT 23 Core i5-13500HX 32 GB DDR5 1500 MHz OpenCL 4067
Acer Predator Helios Neo 16 PHN16-71 Core i5-13500HX 16 GB DDR5-4800 1500 MHz OpenCL 3952
HP Omen 16-wf0xxx Core i5-13500HX 16 GB DDR5 1500 MHz OpenCL 2961
Lenovo LOQ 15IRX10 Core i5-13450HX 24 GB DDR5-4800 1450 MHz Vulkan 4463

Even laptops with the same Core i5-13500HX show noticeable differences in results, so a single test cannot be considered typical for all configurations. In OpenCL, the tested models score approximately 3000-4000 points. The powerful HX processor does not compensate for the limitation of 16 EU.

The difference between laptops with the same processor indicates that results depend on the specific system configuration.

Graphics Frequency in Different Processors

The maximum frequency of the integrated graphics is 1.45 GHz for the Core i5-13450HX, 1.50 GHz for the Core i5-13500HX, and 1.55 GHz for the Core i7-13650HX.

The 0.384 TFLOPS mentioned corresponds to the 1.50 GHz variant. The FP32 performance varies for the 1.45 GHz and 1.55 GHz versions.

In diagnostic programs, this iGPU is sometimes identified as Intel UHD Graphics 770. This does not mean that its performance matches that of the desktop UHD Graphics 770. It is better to distinguish versions of UHD Graphics by the number of EU and the maximum core frequency.

Why HX Processors Have Only 16 EU

HX processors are primarily installed in gaming laptops and mobile workstations. In such systems, the main graphical load is taken on by the discrete graphics card, so high integrated graphics performance is not required here.

Intel UHD Graphics 16EU supports hardware video decoding, Quick Sync Video, and output to external displays. In hybrid mode, the laptop can operate on integrated graphics without involving the discrete GPU, thereby saving battery charge.

Gaming

Without a discrete graphics card, one can only expect to run simple games or older titles with low settings. The performance of 16 EU is insufficient for modern demanding games.

The gaming performance of laptops with Core i5-13450HX, Core i5-13500HX, and Core i7-13650HX is primarily determined by the installed discrete graphics card.

Conclusion

Intel UHD Graphics 16EU serves a secondary role in Raptor Lake-HX and is not designed for serious 3D loads. When choosing a laptop with an HX processor for gaming and 3D tasks, the model of the discrete graphics card is more important than the specifications of the integrated graphics.

Tensor Cores
?
Tensor Cores are specialized processing units designed specifically for deep learning, providing higher training and inference performance compared to FP32 training. They enable rapid computations in areas such as computer vision, natural language processing, speech recognition, text-to-speech conversion, and personalized recommendations. The two most notable applications of Tensor Cores are DLSS (Deep Learning Super Sampling) and AI Denoiser for noise reduction.

TMUs
?
Texture Mapping Units (TMUs) serve as components of the GPU, which are capable of rotating, scaling, and distorting binary images, and then placing them as textures onto any plane of a given 3D model. This process is called texture mapping.

Memory Bus
?
The memory bus width refers to the number of bits of data that the video memory can transfer within a single clock cycle. The larger the bus width, the greater the amount of data that can be transmitted instantaneously, making it one of the crucial parameters of video memory. The memory bandwidth is calculated as: Memory Bandwidth = Memory Frequency x Memory Bus Width / 8. Therefore, when the memory frequencies are similar, the memory bus width will determine the size of the memory bandwidth.

Memory bandwidth refers to the data transfer rate between the graphics chip and the video memory. It is measured in bytes per second, and the formula to calculate it is: memory bandwidth = working frequency × memory bus width / 8 bits.

Theoretical Performance

FP32 (float)
?
An important metric for measuring GPU performance is floating-point computing capability. Single-precision floating-point numbers (32-bit) are used for common multimedia and graphics processing tasks, while double-precision floating-point numbers (64-bit) are required for scientific computing that demands a wide numeric range and high accuracy. Half-precision floating-point numbers (16-bit) are used for applications like machine learning, where lower precision is acceptable.

ROPs
?
The Raster Operations Pipeline (ROPs) is primarily responsible for handling lighting and reflection calculations in games, as well as managing effects like anti-aliasing (AA), high resolution, smoke, and fire. The more demanding the anti-aliasing and lighting effects in a game, the higher the performance requirements for the ROPs; otherwise, it may result in a sharp drop in frame rate.
