Comparing Intel’s Graphics: UHD 770 vs 730 vs HD 630 Difference

Comparing Intel's Graphics: UHD 770 vs 730 vs HD 630

Choosing the right integrated graphics card can be confusing, especially with seemingly similar options like Intel’s UHD Graphics 770, 730, and HD 630. While they may appear alike, subtle differences make a big impact on performance and capabilities. Let’s delve into the technical details to guide your choice.

Core Architecture:

The key differentiator lies in the underlying architecture. UHD 770 and 730 boast the newer Xe architecture, offering improved performance and efficiency compared to the older Gen9 used in HD 630. Xe brings features like:

  • Higher Execution Units (EUs): UHD 770 has 32 EUs, 730 has 24, and HD 630 has 24. More EUs translate to better parallel processing, boosting performance.
  • Enhanced Clock Speeds: UHD 770 reaches up to 1.55 GHz, 730 reaches 1.5 GHz, while HD 630 maxes out at 1.1 GHz. Higher clock speeds directly translate to faster processing.
  • Advanced Media Engine: UHD 770 and 730 decode newer HEVC 12b and VP9 10b codecs for smoother video playback and encoding. HD 630 is limited to HEVC 10b and VP9 10b.

Expect the UHD 770 to be the clear winner in raw performance due to its higher EU count and clock speeds. This translates to smoother gameplay in esports titles and basic AAA titles at lower settings. UHD 730 sits close behind, also suitable for casual gaming. HD 630 is limited to older games and basic multimedia tasks.

Beyond Performance:

The newer architectures offer additional benefits:

  • DirectX 12 Ultimate Support: UHD 770 and 730 utilize the latest DirectX features, enhancing visual effects and compatibility with modern games. HD 630 stops at DirectX 12.
  • Vulkan 1.2 Support: Newer Vulkan API support in UHD 770 and 730 improves efficiency and performance in Vulkan-based games and applications. HD 630 is limited to Vulkan 1.0.

UHD 730 vs 770 for 4k Transcoding:

Both UHD 730 and 770 are good options, but here’s a quick breakdown:


  • 770: Offers a noticeable performance boost over 730, potentially handling 8-10 simultaneous 4k transcodes.
  • 730: Still capable, managing 6-8 transcodes comfortably.

HDR Tone Mapping:

  • Windows users beware! Tone mapping drops transcoding capabilities significantly for both GPUs. Consider Linux or dedicated GPUs for HDR.
  • Unraid (Linux-based) users are good to go with either.

Key Differences:

  • 770: Two MFX video engines, slightly higher clock speeds.
  • 730: One MFX engine, slightly lower clock speeds.


For occasional 4-5 transcodes, both are suitable. Go for the 730 if budget is tight. For frequent or more demanding tasks, the 770 will give you more headroom.

Additional Notes:

  • Consider your transcoding drive speed (NVMe recommended) and network bandwidth.
  • RAM transcoding (memdisk) is an option to reduce NVMe writes but isn’t essential with fast NVMe drives.

Choosing the Right Option:

Your choice depends on your needs and budget:

  • Casual Gamers: UHD 730 offers a sweet spot of performance and price for casual gaming and everyday tasks.
  • Demanding Users: UHD 770 is ideal for moderate gaming and demanding content creation, justifying the slightly higher cost.
  • Basic Needs: HD 630 suffices for web browsing, video playback, and light office work on a budget.

Remember: These are integrated graphics, not dedicated GPUs. Don’t expect high-end gaming performance from any of these options.

Beyond the Numbers:

This comparison paints a broad picture, but specific laptop models with these graphics may have variations in performance due to factors like cooling solutions and system-level optimizations. Research specific models for real-world benchmarks and user reviews.

The Future of Integrated Graphics:

Intel is expected to continue improving its integrated graphics offerings with future generations. Staying updated on these advancements will help you make informed decisions when choosing your next laptop.
