Shulou(Shulou.com)11/24 Report--

In the past RTX 30 series notebook era, the Seven Rainbow General Star series has always been famous for its high cost performance and after-sales service beyond the price. At a time when the RTX 40 series laptop GPU is updated with the 13th generation Core, the mainstream star X15 AT has also been updated with the 2023 version of the RTX 4050 laptop GPU.

Interestingly, this time X15 AT 23 not only upgraded the GPU,CPU, but also upgraded from the H45 series standard pressure core to the H55 core HX series processors, which can match the performance of the modern table-level processors. The version received by CTOnews.com is i7-13700HX + RTX 4050 Laptop GPU, and the initial price is expected to be 7499 yuan. In this article, let's evaluate its specific performance in detail.

Design Seven Rainbow Star X15 AT 23 is a standard 15.6inch 16:9 game book. Recently, it feels relatively small after touching 17.3in and 16in notebooks. BWH is 359.5 (W) x 238 (D) x 26.9 (H) mm, weighs about 2.35KG and is of regular size.

X15 AT will upgrade the metal customized side A, but still continue the concept of the national trend of the star series, and carve a vigorous "will" on the A side. But the design of side An is a little different. A new metal drawing area is added to the top, showing the Logo of the seven rainbows. This splicing design adds a lot of color to the appearance of the fuselage.

Open the B side, is a 1080p 144Hz IPS screen, the color coverage reached 72% NTSC, the measured color gamut coverage is 84.9% sRGB, the color gamut volume is 90.5% sRGB, the brightness is about 325nit. It is a high color gamut screen with a decent look and feel.

C side is a RGB backlit keyboard, the key position is very reasonable, the direction key and keypad are taken care of, and the lighting can be customized through the control software. Below the keyboard is a touchpad of medium size and made of plastic.

The D side is made of plastic, with a cushion design and a large area air inlet. The huge heat dissipation module can be seen clearly from the hollowed-out bottom cover. We will know the specific heat dissipation design later.

The whole machine has 1 USB2.0+1 USB3.2 Gen2 Type-An interface, 1 USB Type C (USB3.2Gen 2), one lightning port, one HDMI interface, one miniDP, a group of 3.5mm audio interface, DC power interface and gigabit network port. Among them, lightning port, HDMI and miniDP interface can all be used for video output, so it can even form four screens to achieve rich expansion.

Hardware analysis We have this version of the Seven Rainbow X15 AT 23 to upgrade the CPU to Intel's latest 13-generation Core i7-13700HX processor. I7-13700HX adopts upgraded Intel 7 process, has 8 performance cores and 8 energy efficiency cores, and consists of 16 cores, 24 threads, maximum Rui frequency 5.0GHz, maximum Rui frequency 3.7GHz, cache 30MB, basic TDP of 55W, and maximum power consumption of 157W. This means that the cooling module of the star X15 AT 23 must also be upgraded.

In terms of GPU, the 2023 X15 AT we have is a RTX 4050 notebook computer GPU. If you have seen the evaluation recently, you must know that the RTX 4050 notebook computer GPU is the most cost-effective of the three new cards released this time. Its underlying architecture has been drastically upgraded to Ada Lovelace architecture, and DLSS, the killer of software, has also been upgraded to DLSS3. Although the fuselage can provide 140W full power performance release, but the actual game 80-100W has a pretty good performance, for an inch of gold notebook is quite suitable. RTX 4050 notebook computer GPU has 2560 CUDA cores, 6GB GDDR6 video memory, video memory bit width 96bit, frequency up to 2370MHz.

So, will the mold of Star X15 AT be able to move this generation's fully upgraded configuration? Let's take a look at the machine next. As can be seen from the picture below, the X15 AT 23 still uses a six-heat pipe double-fan heat dissipation module, but the heat pipe is covered with a layer of copper, which has a certain homogenizing effect, which is stronger than the traditional heat pipe.

Below the heat dissipation module is a memory slot, which comes with a DDR5 4800MHz memory with a capacity of 16g, and a slot is reserved for capacity expansion. It is recommended that everyone add a 16G one to double the reading and writing speed.

The self-contained hard disk is intel's 670p hard disk, which is a middle hard disk of PCIe3.0*4, and the particles are QLC particles. It is worth mentioning that the star X15 AT 23 has reserved an extra M.2 position. Both positions support the ultra-high speed of PCIe 4.0 4. If you are not satisfied with the speed and capacity, you can expand the capacity by yourself.

The battery is also a change from the past tradition of the star series, the capacity has been increased to the 73Wh, with the nuclear display output mode, the battery performance can be expected.

How on earth will the performance of the cooling system of X15 AT 23 be released? We then use AIDA64 for single-baking FPU,15 minutes, the CPU temperature stabilized at 97 ℃, when the CPU power consumption reached about 115W, this performance release is absolutely amazing.

Then we use FurMark doughnuts to bake for GPU,15 minutes, the core temperature is stable at 84.1 ℃, and the power consumption is stable at 140W, which is more than enough for the RTX 4050 laptop GPU.

Next, we run the above two software at the same time to simulate the maximum pressure and run the double baking for 15 minutes. After 15 minutes, the CPU is stable at 63W and 88 ℃, and the GPU is stable at 140W and 84.7 ℃. The graphics card can maintain full power consumption throughout the process, and the CPU is also running on the standard power consumption of 55W. However, it is worth mentioning that the fan noise is also very loud at this time, so it is better to limit the daily use.

In terms of running points, the RTX 4050 Laptop GPU can basically release all the performance, and the GPU theoretical score of 3DMark TimeSpy reaches 8626, which is almost the same as that of the previous generation RTX 3060 Laptop GPU, but the power consumption is much lower. No wonder everyone praises RTX 4050 Laptop GPU as a divine card.

In R20, which represents the theoretical performance of CPU, the scores of single thread and multi-thread are 668 and 8822 respectively. In R23, the score is 1737 for single core and 22672 for multi-core, which is very close to the previous generation of i9-12900HX flagship processors, and it is commendable to be used in notebooks at this price.

The QLC hard disk of Intel 670p is a high-performance hard disk that can expand the capacity of PCIE 4.0if it has the requirement of performance.

The memory is the standard 4800MHz DDR5 notebook memory, the running score is also in line with the normal performance of a single DDR5 notebook memory. If you add a "double channel" in the same group, your reading and writing scores can be doubled again.

It can be seen from the above that the theoretical performance of Seven Rainbow Star X15 AT 23 is quite remarkable. So how does it perform in the actual game? It is worth mentioning that the star X15 AT 23 also supports the single display direct connection function, which can be manually switched in the BIOS to further improve the number of frames of e-sports 's game, so all the following games will be tested in 1080p resolution + highest picture quality + single display output mode, and DLSS will be opened to the quality file DLSS. If there is DLSS3, the number of frames of the switch DLSS3 will be tested separately.

First of all, e-sports game, we selected "CS:GO", "PUBG", "forever robbed forever" and "APEX Legend" four mainstream e-sports games for testing. Measured in the "CS:GO", the running BenchMark can reach an average of 413 frames, which can run all over the electronic competition screen.

On the side of "PUBG", it is measured that it can run to 131frames under the highest picture quality, which can satisfy the high-frame play of the highest picture quality. If you want to play with 144 frames running full of video games, you can consider adjusting it to the commonly used "three extremes" picture quality.

In the domestic martial arts Battle Royale Games "forever robbed forever", the highest picture quality + quality file DLSS can reach an average of about 143frames, basically running full of this electronic competition screen.

In "APEX Legend", the average number of frames can reach 142frames, which can basically meet the needs of 144Hz screen. If the NVIDIA Reflex low delay is enabled in the setting, the firing delay can be further reduced.

From our above tests, the vast majority of e-sports games can meet the 1080p 144Hz video game, and the picture quality is also the highest picture quality, it seems that the RTX 4050 laptop GPU is really strong. Next, let's test some mainstream 3A games. In Tomb Raider: shadow, under the highest special effects of 1080p, the number of frames is as high as 117 frames, so it's not a problem to play.

In the classic 3A masterpiece "the Wild Dart 2: redemption", the star X15 AT 23 also showed good results, running to an average of 78 frames at the highest 1080p picture quality, and the play experience was very smooth.

In the past, the RTX 3050 laptop GPU was difficult to challenge the highest quality 3A X-ray chase, but now the RTX 4050 laptop GPU can do it! For example, in Control, even if you turn on the highest quality and highest light pursuit, you can achieve a full average of 91 frames.

In the exploding new film Heart of the Atom, the complex scene with the highest quality light on can also reach an average of 61 frames. On the one hand, the RTX 40 series notebook GPU is strong, on the other hand, this game optimization is really good.

As for the more stressful 3A masterpieces, DLSS3 technology is about to come out. ‏ 's so-called ‏‏ DLSS3 is a performance multiplier ‏‏ technology ‏‏ driven by AI, driven by a new fourth-generation Tensor Core and a new optical flow accelerator, is the latest version of NVIDIA's acclaimed deep learning supersampling technology, and has a groundbreaking optical multi-frame generation function, which will open a new era of NVIDIA RTX neural network rendering games and applications. ‏

‏ simply put, the past DLSS2 is to render a low-resolution image, and then AI zoomed in to high-resolution, to achieve the improvement of image quality and frame number. The new DLSS3 not only is compatible with DLSS2, but also adds a frame generation function, which can insert a new frame calculated by AI between two real frames to double the number of frames. Combined with the super-resolution function of DLSS2, AI can reconstruct up to 7/8 display pixels, compared with no DLSS, the game performance can be improved by up to 4 times ‏‏ ‏‏! ‏

‏ Let's first take a look at the most stressful ‏‏ "Cyberpunk 2077" ‏‏. ‏‏ ran its own BenchMark under the highest quality super light of ‏‏ 1080p ‏‏, and got the following data. ‏‏ averages only 28 frames by default, so it can't play smoothly. Even when DLSS2 is turned on, it can reach 50 frames. However, when the DLSS3 option is fully on, the number of frames can be increased by more than 3 times, and the average frame can be increased to about 94 frames, meeting the requirements of 1080p high frame playback. It seems that DLSS3 technology is indeed outstanding. ‏

‏ legendary 3A masterpiece "Wizard 3" has also recently updated the next generation version, which greatly improves the configuration requirements, but also provides the support of DLSS3 technology, which is undoubtedly good news for the ‏ RTX 40 series laptop GPU ‏. ‏

‏ from the frame number test, the ‏ RTX 4050 laptop GPU ‏ is still very difficult to catch up with all the fun Wizards 3. Without DLSS, it even has an average of 23 frames. The average frame in the DLSS 2 balanced gear is only 34 frames. But if you turn on DLSS3, you can achieve an average of 64 frames. 60 frames of play can be achieved in most scenes. ‏

‏ in another picture quality explosion of the next generation 3A masterpiece "Plague Legend: Requiem", we also need the blessing of DLSS 3 technology to achieve high-frame smooth play. ‏

The optimization of ‏ 's Plague Legend: Requiem is very good, even without DLSS, it can be played at a frame rate of more than 40 frames. If the DLSS 3 quality file is turned on, the number of frames directly doubles to an average of 88 frames, and the image quality does not decline much. ‏

In my opinion, the RTX 4050 laptop GPU is a perfect match for a 1080p screen. At 1080p resolution, it allows e-sports games to run at 144frames and 3A masterpieces to reach the highest picture quality of more than 60 frames. In the next few years, the RTX 4050 laptop GPU + DLSS3 will be the solid backing of Changkuan3A.

In summary, from the author's recent test of the RTX laptop GPU in 4050-60-70, the RTX 4050 really gave me the biggest surprise. Compared with the previous generation, it is almost a qualitative leap, at the same time, the new features of this generation are also consistent. With extremely low power consumption, the RTX 4050 laptop GPU will be the best choice for playing 1080p 3A.

If you want to experience RTX 4050 with a high performance-to-price ratio, then the star X15 AT 23 we tested today will be a cost-effective choice. In terms of price, the initial price of i7-13700HX + RTX 4050 Laptop GPU version is 7499 yuan. And the more cost-effective version of i5-13500HX + RTX 4050 can start at 6999 yuan.
