Performance testing
The Star X15 AT (2022 edition) we have in hand is a Corei7-12700H processor and a GeForce RTX 3060 Laptop graphics card, which uses a GA106 GPU, ampere architecture, has 3840 CUDA units, the base frequency is 1342MHz, the Boost frequency is 1680MHz, equipped with 192bit/6GB GDDR6 video memory, and the video memory equivalent data frequency is 14000MHz. Using the PCI-E 4.0 x8 interface, the basic TGP is 110W, and the maximum dynamic TGP can reach 140W, and the graphics card is directly connected to the display.
、
The Core i7-12700H has 6 P-Core and 8 E-Core, a total of 20 threads, P-Core base frequency 2.3GHz, maximum acceleration frequency 4.7GHz, E-Core base frequency 1.7GHz, maximum acceleration frequency 3.5GHz, equipped with 24MB L3 cache, Intel officially gives the processor base power consumption is 45W, the highest turbo power consumption is 115W, but these things can be through Control Center 3.0 console to adjust, with 8GB*2 DDR4-3200 memory, timing is 22-22-22-52.
Does not compare performance in mode correctly
The CPU power consumption settings of different cooling modes are shown in the table above, the performance mode of Tau is up to 96 seconds, the entertainment mode is only 28 seconds, and the other two modes are only 8 seconds, in fact, rainbow will star X15 AT (2022 version) using AC power and the notebook's power plan when using built-in battery power is very similar, that is, the performance mode PL1 is 80W when plugged in, and 70W when using battery.
We used CINEBech R20 to simply compare the CPU performance in different cooling modes, the performance in performance mode is the best, Tau time is enough to run the full test, entertainment mode is not OK, running will become PL1, power saving mode Although the display is PL2 = PL1 = 30W, but in fact the CPU will be limited to 15W after 8 seconds and quiet mode, because the PL2 of these two modes is quite low, so the score and performance are very different from the entertainment mode.
Through the 3DMark CPU Profile test, it can be seen that in fact, the performance and entertainment mode, the CPU has no performance gap when it is 1 to 4 threads, and the gap from 8 threads upwards is gradually widening, and the CPU gap between quiet mode and power saving mode is very small.
Next, we use 3DMark Time Spy to test the performance of graphics cards in each mode, when testing the CPU, quiet mode and power saving mode are different, but the difference between the graphics card in these two modes is quite large, the graphics card performance in quiet mode is close to the entertainment mode, much better than the power saving mode, and the graphics card performance of the performance mode is naturally the best.
CPU performance testing
The number of Core i7-12700H cores used by the Star X15 AT (2022 edition) is actually the same as the flagship Core i9-12900H, the two are basically only the difference in frequency, the Core i7-12700H P-Core is 300MHz lower, and the performance is actually not much worse.
All tests were measured in performance mode, with the Core i7-12700H on the Star X15 AT (2022 edition) running score 13% higher than the previous flagship Core i9-11980HK, and the multi-threading was 22% higher.
The CPU-Z comes with similar test results, and the Core i7-12700H has widened the multi-thread gap, 27% ahead of the Core i9-11980HK.
In Pov-Ray's Benchmark, the Core i7-12700H multithreading lead has exceeded 30%, and single threading is 14% higher than the Core i9-11980HK.
The 7-zip uses the latest version of the built-in Benchmark test, and the Core i7-12700H has 11% better compression performance and 15% higher decompression than core i9-11980HK.
Judging from the test, the Core i7-12700H used by the Star X15 AT (2022 edition) has surpassed the previous generation of flagship processors in performance, and it is a processor with quite good performance.
Game testing
As a game book, the star X15 AT (2022 version) is equipped with RTX 3060 Laptop graphics card, its 3DMARK test results are shown in the figure above, as a graphics card selected for more high-end game books, it has high performance itself, and also supports real-time ray tracing and DLSS, which can bring a better experience to gamers.
The star X15 AT (2022 edition) the actual game performance is also quite strong, we tested the game is all open the highest quality, this game can run quite smoothly, "Tomb Raider: Shadow" test is not open DLSS, if turned on, even the quality mode can get higher fluency, the latest "Eldon Ring of Law" is limited by the maximum frame limit of 60fps, if you use cracked patches, you can get a higher frame rate.
SSD performance testing
The SSD model used by Rainbow Star X15AT (2022 edition) is Western Digital SN530 512GB, which is the more popular Western Digital OEM SSD on the market, with TLC flash memory, and the interface is PCI-E 3.0 x4.
CDM's real-life performance test, continuous read and write speeds of 1813/1800 MB/s, 70% read and 30% write mixed test speed of 1519MB/s, 4K random read latency of 81us, random write latency of 14us, is a fairly standard mainstream SSD.
Peak test, QD8 continuous read and write speed is 2488/1817MB/s, mixed read and write speed is 1900MB/s, QD32 random read and write IOPS are 219K and 148K, peak random performance is actually quite good, continuous performance is average, but usually basically can not run the peak test of this queue depth.
Endurance test
Star X15 AT (2022 version) unplugged AC power will not automatically switch performance mode, screen brightness to the battery below a certain value will automatically drop down, endurance test is in performance mode to run, screen brightness 100%, PCMark 10 modern office battery test ran for 1 hour and 44 minutes, endurance is not too long, performance score of 7570, indicating that the performance is not bad under pure battery power, If you want to get better battery life, you can change the power mode to quiet or power saving mode.
Thermal test
Here the AIDA 64 FPU single baking CPU is used for CPU single baking test, the 3DMark Time Spy pressure test is used for GPU single baking test, and the AIDA 64 FPU and 3DMark Time Spy pressure test are run simultaneously for double baking test, and HWinfo is used to record data, and the room temperature is 24 ° C during the test.
Measured AIDA 64 FPU grill process peak CPU Package power consumption can reach 115W, but the temperature also instantly peaked, and then the power consumption will gradually decrease, Tau exhaustion will enter the PL1 stage, this stage of temperature will be stable near 91 °C, power consumption will be maintained at about 68W, the grill process, The peak frequency of P-Core can reach 4.1GHz, E-Core can reach 3.3GHz, and by the PL1 stage, the P-Core frequency can be stabilized at 3.2GHz, and the E-Core can be stabilized at 2.7GHz.
In terms of GPU, the RTX 3060 Laptop equipped with the Star X15 AT (2022 edition) can peak power consumption to 134W, and the power consumption of the graphics card is basically stable at more than 130W at the beginning of the load, but when the temperature exceeds 87 ° C, the power consumption begins to drop automatically, and after the 3DMark Time Spy stress test is stable, its power consumption is roughly between 110W and 115W.
The frequency/power consumption curve of the GPU is shown in the table above, the highest frequency can reach 1905MHz, and the frequency of the stage when the power consumption is relatively stable in the latter stage will fluctuate between 1627MHz and 1747MHz.
When double roasting, you can see the power consumption strategy tilted towards the GPU, which is to ensure the game experience, in the game scene, the 14-core 20-thread processor is dissatisfied, and more power is allocated to the GPU to help the gaming experience. After stabilization, it can be seen that the CPU part is maintained at about 35W power consumption, the GPU part is maintained at about 110W power consumption, and in terms of temperature, the CPU after stabilization is about 77 °C, while the GPU is around 87 °C.
The above picture is a thermal imaging map of double baking, the hotspot of the entire notebook in the center of the keyboard, can reach 50 ° C, that position is exactly the CPU and GPU area, and the gamer's commonly used WASD key area and palmrest area is about 33 ° C, below the body temperature, there will be no obvious hot feeling.
