But the maximum frequency varies between 1050 – 1200 MHz for different CPU Models. Irrespective of the CPU, the base clock of the GPU in all devices is 300 MHz. As the performance of Integrated Graphics is severely limited by the System RAM, the DDR4 devices will have significantly better graphics performance than the LPDDR3 ones. You can connect up to 3 Monitors at a time but this also requires 3 output ports (HDMI/VGA/Display Port/DVI/USB-C/Thunderbolt 3) on your Laptop/PC.Īll the CPUs with this Integrated Graphics have support for both LPDDR3 & DDR4 RAM and this has a significant impact on the performance. This cache is one of the primary reasons that make Iris Graphics faster than HD and UHD Series.ĤK Display is also supported so you can connect your MacBook or Mini-PC to an external 4K display. It has 128 MB Cache which is twice that of Iris Graphics 650 & 640. Like other GPUs in Intel Iris Series, this one has eDRAM Cache which Intel HD & UHD Series Graphics lack. It has 48 Execution units, the same as the Iris Plus 650, 645, and 640 and twice that of UHD 630. The Iris Plus 655 is Intel’s GT3e Tier GPU which places it a notch above the UHD Graphics 620 & 630. Even though the resultant Video Quality after using Hardware Encoding isn’t on the same level as H.264 Software Encoding, it is still acceptable to most people.
Just like other Intel iGPUs, the Iris Plus Graphics 655 has the QuickSync feature which uses Hardware Encoding and reduces the export times significantly in Video Editing applications like Adobe Premiere and Final Cut Pro. But if you’re just a casual user who needs a computer for Office Work, Entertainment, Light Gaming, and Browsing, go with an Integrated one. If you’re into Editing, Heavy-Gaming, or use programs that can take advantage of a Powerful GPU, I’ll recommend a dedicated GPU. This allows the user to balance high-performance and power-efficiency. *Some Laptops have both Integrated and Dedicated GPUs and it is possible to switch between them. But if your tasks can’t take advantage of a discrete card (such as Office Programs), you’re better off with an Integrated one.
If the application that you use can take advantage of a powerful GPU, you will observe a significant improvement in performance. Though the dedicated cards will result in better rendering and gaming performance, they also consume more battery and has the potential to run hotter (*).
