Gigabyte small carving PRO Z690 motherboard evaluation: 16+1+2 phase power supply, easily bring up a new generation of i9!
It’s only been more than half a year since the release of the 11th generation Core.Intel The 12th generation Core processor is coming, as Intel this year.CPUThe "year-end answer sheet" on the road map, this generation of processors really has a lot to watch, except that the mixed architecture is installed on the x86 processor on the desktop for the first time, the new technology is adopted on the desktop for the first time, the package area is increased, and DDR5 is supported.memoryAnd PCIe 5.0, another key point is, of course, the new generation chipset-Intel Z690 chipset.

Today we will use a new generation of motherboards-GigabyteXiaodiao PRO Z690 AORUS PRO motherboardTo decrypt the upgrade point of the motherboard equipped with Z690 chipset.
This time, the Z690 chipset has brought us several new things:
1. The chipset has native PCIe 4.0 channels.
2. The DMI bus channel is upgraded to DMI Gen 4.0 x8, and the bandwidth is doubled.
3. Support Wi-Fi 6E wireless network
4. Intel VMD technology is supported for the first time, and users can manage PCIe devices conveniently.
5. Add a USB 3.2 Gen 2×2(20Gbps) high-bandwidth interface support.

Of course, new things need to be savored carefully to find the essence. First, put an official Intel Z690 chipset architecture diagram, and then analyze it.

It can be seen that the Z690 chipset has 12 native PCIE 4.0 channels, and also has 16 PCIe 3.0 channels, a total of 28 PCIe channels. For the old chipset that has been 24 PCIe 3.0 channels for several generations, the Z690 has finally increased the native channels of the chipset, and users want to expand high-speed PCIe devices or install more.display cardIt will be easier.
The DMI 3.0 bus, which has persisted for several generations, has also ushered in changes on the Z690 chipset. Z690 upgraded DMI to Gen 4.0 for the first time, and provided 8 channels at the same time, which should be due to the increase of native PCIe channels. The original DMI channel bandwidth should not meet the existing demand. The DMI channel bandwidth of Z690 chipset is directly doubled compared with DMI Gen 3.0 x8 of Z590, which means that the transmission efficiency between the processor and chipset will be higher.

In addition, compared with Z590, Z690 chipset benefited from the performance improvement of UHD770 core display, and the independent display output support increased to four; The SATA 6Gbps interface support has been upgraded from 6 to 8, and the native support for PCIe hard disk RAID array; On the network side, the wireless network card was changed to AX211 supporting WiFi-6E. The bandwidth, transmission performance and network performance of the motherboard have been greatly improved, and the Z690 motherboard can be said to be the most outstanding consumer motherboard at present.

As for PCIe 5.0 interface, there is no corresponding product yet, but it is undeniable that PCIe 5.0 will be the mainstream in the future, and it will be useful when the graphics card supporting PCIe 5.0 comes out.
The 12th generation Core is the first x86 processor with mixed architecture. Naturally, many users are worried about its compatibility and optimization. Therefore, Intel specially designed a component on the hardware level-Intel Thread Director, which can assist the system in task allocation, so that large and small cores can perform their respective duties and maximize task processing efficiency.

Intel Thread Director will monitor the instruction combination of each thread of the processor in real time, and then dynamically adjust the guidance according to the running power consumption, running environment and power supply design. At the same time, the cooperation between Intel and Microsoft enables Windows 11 to work with this component and give full play to the best performance of the mixed architecture processor. It can be said that if you want to give full play to the performance of the 12th generation Core, you really can’t live without Windows 11.

Before the performance test, let’s take a look at Gigabyte’s new generation Xiaodiao PRO Z690 AORUS PRO motherboard. This generation of Xiaodiao PRO is divided into DDR5 version and DDR4 version, and models that support DDR4 memory will have a name suffix of "DDR4".

In the CPU advanced settings, you can also set the available number of performance core clusters and energy efficiency core clusters.

For example, some users who need to use the PCIe x16 extension cable for vertical graphics cards need to adjust the PCIe channel rate directly connected to the CPU when encountering compatibility problems. Of course, you can also directly lock in the PCIe 5.0 rate.


First of all, look at the information of CPU-Z 1.97, and we can see that the CPU information of i9-12900K has been well recognized. The total number of 8+8, 16 cores, 24 threads in total, 30MB L3 cache, 10nm process, TDP of 125W, core #0 identified as performance core, and core frequency of 4.9Ghz..

The performance of DDR5 memory is also a concern of many users. After opening XMP, we tested the read-write performance of AIDA64 memory in DDR5-5200 state. The read-write and copy performance of memory is 81,396 MB/s, 73,571 MB/s and 73,349 MB/s, with a delay of 76.1ns. The advantages of DDR5 memory’s large bandwidth have brought about an overall improvement in memory performance.
In terms of memory delay, due to the starting frequency of DDR5 memory of 4800Mhz, the CPU is directly in Gear 2 frequency division mode, so the delay is higher than that of Gear 1.
We used CPU.–Z、CINEBENCH R20、CINEBENCH R23、3D MARKThree softwares perform CPU benchmark performance test.

As can be seen from the chart, due to the brand-new hybrid architecture and scale upgrade, i9-12900K’s CPU single-core and multi-core scores are quite strong, with CPU-Z’s single-core score reaching 828 points and multi-core score reaching 11400.2 points, CINEBENCH R23′ s single-core score reaching 1997 points and multi-core score reaching 27135 points, which is quite amazing in performance.
In the test of 3D MARK software, the i9-12900K, whether in CPU PROFILE, TIME SPY and FIRE STRIKE projects, with the upgrade of IPC and more cores, has completely surpassed the i9-11900K of the previous generation..

For the performance evaluation of daily experience, we use PCMark 10 Extended project to test, including common basic functions, productivity and digital content creation, as well as the game test part, so as to understand the experience of this platform more comprehensively.
After testing, the comprehensive score of the main board is 13,023, and the scores of all items are over 10,000, which means that this platform can have an excellent experience under the Windows 11 system.

In Blender, the benchmark of rendering project, relying on the powerful multi-core performance of i9-12900K and the graphics capability of RTX 3090, the rendering project can basically be completed in a short time.

In the frame number test of the game, we selected five popular masterpieces, all of which have a picture quality setting of 1080P resolution+the highest/ultra-high picture quality. Except for "Subway: Leaving", which requires higher graphics on the GPU, the other games have basically no pressure on the i9-12900K+RTX 3090 configuration..

Finally, we use AIDA64 software to test the Stress FPU of CPU. After nearly half an hour of baking, the CPU performance core is 4.9Ghz, the energy efficiency core is 3.7Ghz, and the power consumption is stable at 245W W. The 16-phase core power supply directly fills i9..

In the process of pressure test, the performance of the motherboard is measured by thermal imager, and the highest temperature of the power supply module is only about 50 degrees, and the highest temperature is the capacitor part not covered by the vest. Thanks to the complete heat dissipation vest of the motherboard, the power supply module can continuously and stably output even under full-load pressure test.

For some players who want to improve their performance, but don’t want to spend too much time tossing, the motherboard can provide an option similar to "one-click overclocking", and many ordinary users can enjoy a higher performance experience with simple operation..

Gigabyte Xiaodiao PRO Z690 motherboard provides the option of CPU UPGRADE in BIOS, and it has built-in default mode and Gaming Profile and Advanced Profile. The difference is that Gaming Profile mode pursues a more stable high-frequency gaming experience, while Advanced Profile mode pursues maximum multi-core performance. Next, we tested the performance of the two modes respectively..

In Gaming Profile mode, the CPU frequency doubled by +1, the performance core frequency was 5.0Ghz, and the energy efficiency core frequency was 3.8Ghz. Compared with the default mode, the benchmark test score was slightly improved. At the same time, it was observed that the voltage of CPU during operation was basically less than 1.3V, and the power consumption and temperature were controlled in an ideal range, which could not only stabilize the output, but also prevent the frequency from being lowered due to excessive temperature.
In the Advanced Profile mode, the CPU frequency doubled by +3, the performance core frequency of the CPU was 5.2Ghz, and the energy efficiency core frequency was 4.0Ghz, which was 4% higher than the benchmark performance of the default mode. At the same time, it was observed that the voltage of the CPU was above 1.4V when it was running at 5.2Ghz, and the power consumption also reached 292.965W, which really reached the limit level. However, for ordinary users, running in the default or Gaming Profile mode can get a better performance. If you need to run in this mode with high load for a long time, you have to consider whether your cooling conditions can withstand it..

From a series of tests, we can see that thanks to the new architecture, multi-core and new Z690 motherboard, the performance of the 12th generation Core has been greatly improved. In terms of experience, the mixed architecture of large and small cores has not been "acclimatized".
