Intel UHD Graphics 64EU Mobile: Overview of Integrated Graphics for Mobile Devices

April 2025

Introduction

Intel UHD Graphics 64EU Mobile is an integrated graphics solution that continues to be popular in budget and mid-range laptops. Despite modest gaming performance, this GPU demonstrates decent capability for everyday tasks and supports modern technologies. In this article, we'll explore who this GPU is suited for and what compromises need to be considered.

Architecture and Key Features

Xe-LP: The Foundation for Mobile Solutions

The architecture of UHD Graphics 64EU is based on Xe-LP (Low Power), an energy-efficient version of Intel's Xe graphics architecture. It is designed to minimize power consumption, which is critical for laptops. The manufacturing process is Intel 7 (previously known as 10nm Enhanced SuperFin), providing a balance between performance and thermal output.

Unique Features

- Intel Quick Sync: Accelerates video encoding/decoding (support for H.265, AV1).

- Adaptive Sync: Provides smooth visuals in games and videos.

- Lack of RT and DLSS: Hardware ray tracing (RTX) and neural networking technologies (DLSS) are not supported. However, there is compatibility with FidelityFX Super Resolution from AMD to boost FPS in games.

Memory: System RAM Instead of Dedicated VRAM

Type and Volume

Intel UHD Graphics 64EU uses system memory (DDR4/LPDDR4x/LPDDR5). The amount of "video memory" is dynamically allocated from RAM (up to 8 GB depending on BIOS settings).

Bandwidth

Speed depends on the type of memory:

- LPDDR5-6400: Up to 102.4 GB/s (dual-channel mode).

- DDR4-3200: Up to 51.2 GB/s.

Tip: Choose laptops with dual-channel memory — this can increase FPS in games by 15-25% compared to single-channel configurations.

Gaming Performance: Modest, but Practical

Average FPS in Popular Games (1080p, Low Settings):

- CS:GO: 60-75 FPS.

- Fortnite (Performance Mode): 45-55 FPS.

- Valorant: 70-90 FPS.

- Cyberpunk 2077 (without ray tracing): 20-25 FPS.

Resolution Support

- 1080p: Optimal for most titles.

- 1440p and 4K: Only for less demanding games (e.g., Stardew Valley) or videos.

Ray Tracing

There is no hardware implementation. Software emulation through DirectX 12 Ultimate reduces FPS to unplayable levels (5-10 frames).

Professional Tasks: Not for Heavy Workloads

Video Editing

- Intel Quick Sync accelerates rendering in Premiere Pro and DaVinci Resolve.

- AV1 support makes the GPU attractive for streamers.

3D Modeling

Blender and AutoCAD work on the OpenCL platform, but complex scenes can cause lag. It is recommended to use models with discrete GPUs.

Scientific Calculations

Support for OpenCL 3.0 allows for simple simulations, but CUDA cores (NVIDIA) are absent.

Power Consumption and Thermal Output

TDP and Efficiency

The graphics are integrated into processors with a TDP of 15-28 W (e.g., Core i5-1240P). The GPU consumption itself is 5-10 W.

Cooling

Even in thin ultrabooks, overheating is rare thanks to an optimized thermal package. However, throttling may occur during prolonged gaming sessions.

Tip: Use cooling pads for laptops with passive ventilation.

Comparison to Competitors

AMD Radeon 680M (RDNA 2)

- Pros for AMD: +30-50% FPS in games, support for FSR 3.0.

- Cons: Higher laptop prices (starting at $800).

NVIDIA GeForce MX550

- Pros for NVIDIA: Better driver optimization, support for DLSS.

- Cons: TDP up to 25 W, affecting battery life.

Conclusion: UHD Graphics 64EU is suitable for those who value battery life and are not willing to overpay for a discrete GPU.

Practical Tips

Power Supply

Integrated graphics do not require separate power. The laptop's standard adapter (65 W) is sufficient.

Compatibility

- Supports Windows 11, Linux (with open-source Mesa drivers).

- For external monitor connections, use DisplayPort 1.4 or HDMI 2.0.

Drivers

Intel releases updates monthly. It is recommended to enable automatic updates through the Intel Driver & Support Assistant.

Pros and Cons

Pros:

- Energy efficiency (up to 8 hours of office tasks).

- Support for AV1 and modern codecs.

- Low laptop cost (starting at $500).

Cons:

- Weak gaming performance.

- Dependence on system memory.

- Lack of hardware ray tracing.

Final Thoughts: Who is UHD Graphics 64EU Suitable For?

This GPU is ideal for:

1. Students — Document work, online courses, light gaming.

2. Office Workers — Video conferencing, multitasking.

3. Travelers — Long battery life and compactness.

If you do not plan to play AAA titles or engage in 3D rendering, Intel UHD Graphics 64EU will be a reliable choice without unnecessary expenses. As of April 2025, laptops with this graphics solution remain among the most affordable on the market, maintaining a balance between price and capabilities.

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.

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.

Pixel Rate

Pixel fill rate refers to the number of pixels a graphics processing unit (GPU) can render per second, measured in MPixels/s (million pixels per second) or GPixels/s (billion pixels per second). It is the most commonly used metric to evaluate the pixel processing performance of a graphics card.

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.
