Introduction

The 16th. In March 2021, Intel introduced its 11th generation of desktop processors. They are also called Rocket Lake desktop processors or just Rocket Lake.  We looked at the Intel Core i9-11900K and Intel Core i5-11600K processors.  We ran extensive performance tests in both multithreaded and single-threaded mode, and also looked at gaming performance in 1080p and 4K.

When it comes to gaming, we tested both processors in combination with a dedicated graphics card, the GeForce RTX 3080 Founders Edition.  The purpose of these tests was to examine how the processor itself affects the performance of the game.  However, there is another aspect of Intel desktop processors, and that is Intel’s integrated graphics processor.

12. Intel Xe Generation Graphics

Intel has long struggled with integrating graphics into its desktop processors.  Of course, because they were integrated and shared system memory for bandwidth, they were never competitive for a serious player.  For 11th generation Rocket Lake desktop processors. In the second generation, however, a change occurred.

Note that the 11th generation Rocket Lake processors are not available. The generation consists of a new architecture for the processor component.  They integrate a 10nm IP into a 14nm package, and it is this new Cypress Cove core that brings the IPC improvements to the processor.  But that’s not all.

Intel also announced its 12. Integrated graphics in Rocket Lake.  This is a significant architectural change from the last generation of Comet Lake processors.  The integrated graph of the 12. The 3rd generation is based on Intel’s Xe architecture from the Tiger Lake range.  Intel’s new Xe graphics cards are now integrated into the new Rocket Lake processors.

With Intel Gen 12 graphics, Intel claims up to 50 percent better integrated graphics performance in 32 EU countries.  The components that make up this graphics pipeline are Gen 12 Display, Gen 12 Media and Gen 12 Graphics.  For the sake of naming it, Intel has chosen to call it the Intel UHD Graphics 750.  But rest assured, the Intel UHD Graphics Xe 750 is largely based on the Intel Xe graphics architecture and differs greatly from earlier generations of Intel UHD Graphics 630.

UHD Intel 750 Graphics

The Intel 630 graphics card was introduced in the Kaby Lake processors and updated in the 2017 Coffee Lake generation as the Intel UHD 630 (GT2) graphics card with higher clock speeds.  It is based on the Gen 9.5 architecture.  It also switched to the Comet Lake generation of processors.  Here’s what the internal workings of the Intel Core i9-10900K look like.  It has 24 execution units and can run at up to 1200 MHz in the i9-10900K core.

With the new Core i9-11900K’s UHD Graphics 750 card, Intel has adopted the new Gen12 Xe architecture of Tiger Lake processors, codenamed Tiger Lake Xe.  It was also called Intel Iris Xe.  The Intel UHD Graphics 750 features 32 actuators and, combined with higher clock speeds and a new architecture, offers a big leap forward in graphics performance.  The Intel Core i9-11900K can run at up to 1300 MHz.  It also supports DX12.1, Vulkan, OpenCL 3.0 and OpenGL 4.5, and Intel QuickSync.

Like all embedded graphics, it uses system memory for memory access.  This means that it is limited by the memory bandwidth of the system.  On the Intel Core i9-10900K Intel Graphics UHD 630 is officially DDR4-2933 and on the Intel Core i9-11900K, Intel Graphics UHD 750 is now officially DDR4-3200.  However, for our test today, we will set the memory frequency to the same value of 3200 MHz for both platforms so that they have the same memory bandwidth.

Intel UHD 750 Graphics Driver

We can use the same Intel graphics driver for the Intel UHD Graphics 630 and the Intel UHD Graphics 750.  Intel has just released support for Rocket Lake in the latest previously released driver for Comet Lake integrated graphics.  This driver is Intel Graphics – Windows 10 DCH Drivers Version 27.20.100.9316.  These drivers are newer than the press driver (9220), which is required for the 11th generation processors to work.  So we test with the best driver you can currently get from Intel for Rocket Lake.

However, these pilots are not without their problems.  If you look at the ReleaseNotes.PDF document, you’ll find a number of known problems.  There are issues with games crashing and freezing, graphical anomalies, flickering and blank screen problems.

Intel Graphics Control Center

After installing the drivers, you can access the Intel Graphics Command Center application in Windows.  This application allows you to manage many aspects of the display settings.  You can add games to it, allowing you to define custom 3D settings for each game.  You can change the anti-aliasing settings using the Application Controlled, Always On, CMAA Only or Always Off options.

CAMA stands for conservative morphological smoothing and is a form of AA post-processing.  In terms of performance, it is between FXAA and SMAA 1X in terms of computational overhead.  It is designed for integrated graphics performance and offers better image quality than FXAA.  You can even adjust the level of edge smoothing to match performance in the control center.  There are also options for anisotropic filtering, VSYNC and texture filtering with a performance or quality preference.  There is also an option to add sharpness to games if they are low resolution or blurry.

Under Settings you will find other options that allow you to adjust the performance of the game.  Games that use tessellation have an adaptive mosaic option that can be enabled in the control center.  This ensures that any game that uses tessellation will reduce the amount of tessellation that occurs.  This should speed up the work.  Of course, you can also disable the mosaic in the game for better performance.  There is also support for integer scaling to reduce blur in pixel-based games.

To our surprise, Intel also supports the Smart VSYNC option.  It controls the maximum frame rate to minimize stuttering and tearing.  It indicates that it should be enabled on non-VRR (Variable Refresh Rate) or non-adaptive synchronous displays to reduce stuttering and tearing by limiting the monitor’s refresh rate.  It’s a feature we weren’t expecting, but apparently Intel offers it if you don’t have an Adaptive Sync or VRR display.
