Today, we received the Lenovo ThinkPad T14 Ryzen Edition. This laptop is equipped with the top Ryzen 7 PRO 4750U processor in the Ryzen PRO 4000U series.
To put it simply, in addition to the commercial-oriented security, stability, and manageability brought by AMD Pro technology, the Ryzen 7 PRO 4750U processor also has a hyper-threading function compared to the Ryzen 7 4700U, with a base frequency of 1.7GHz, The highest acceleration is 4.1GHz, the second-level cache is 4MB, the third level cache is 8MB, 7 Vega CU units, 448 stream processors, the frequency is 1600MHz, and the power consumption is 15W.
Of course, as a business laptop, in addition to the Ryzen 7 PRO 4750U processor, the ThinkPad T14 Ryzen Edition still has some differences from the traditional thin and light laptops:
1. Passed 12 U.S. MIL-STD-810G military standard tests
ThinkPad T14 Ryzen Edition has passed 12 U.S. MIL-STD-tests including drop test, low-temperature test, high-temperature test, altitude test, dust test, mechanical shock test, explosion-proof test, vibration test, fungus test, etc. The 810G military standard test ensures stable operation in various harsh environments.
2. Privacy camera
When connected to the Internet, business laptops may be controlled by hackers. The ThinkPad T14 Ryzen Edition uses a sliding black valve. When the camera is not in use, you can directly slide the valve to block the camera.
3. Built-in 8GB/16GB single-channel DDR4 3200MHz memory, and a SO-DIMM slot for expansion
If you are just for office use, buy the 16GB memory version directly; if you want to play games, it is recommended to buy the 8GB memory version and add another 8GB memory to form a dual-channel mode. Of course, if the budget is sufficient, a 32GB dual-channel is not impossible.
Of course, in addition to these, the ThinkPad T14 keyboard has always had a very good reputation. The keyboard input experience is better than most thin and light laptops. In addition, the addition of the Intel Wi-Fi 6 AX201 wireless network card is also a small highlight.
ThinkPad T14 is a high-end business laptop that inherits ThinkPad elements. The body is made of aluminum alloy. The A-side is designed with a skin-like texture coating, which is delicate and moderately frictional.
The laptop uses a 14-inch display with a resolution of 1920*1080, a 45% NTSC color gamut, and brightness of 250nit.
There are two Type-C ports on the left side of the fuselage, of which the left one is a full-featured port, which can be used for charging, video output, and file transfer. On the side is a Type-C Thunderbolt 3 port that supports professional docking stations.
It also has an HDMI, a USB 3.1 Gen1, a 3.5mm headset all-in-one port, and a Micro SD card reader. There are a USB 3.1 Gen1 and an RJ45 port on the right side of the fuselage, and there is a row of cooling air outlets in the middle.
2. Performance test: 19% stronger than Ryzen 7 4700U
Ryzen 7 PRO 4750U has a single-thread score of 502 and a multi-threaded score of 4103.
In the wPrime 32M single-threaded performance test, the Ryzen 7 PRO 4750U took 30.4 seconds; the multi-threaded wPrime 1024M took 115 seconds.
3. CineBench R15
In the CineBench R15 test, the Ryzen 7 PRO 4750U has a single-thread score of 179cb and a multi-threaded score of 1383cb.
4. CineBench R20
Ryzen 7 PRO 4750U has a single-thread score of 455cb and a multi-threaded score of 3062cb.
The POV-Ray single-core score of the Ryzen 7 PRO 4750U is 440PPS, and the multi-threaded score is 2879PPS.
3. Screen and SSD performance
The screen of ThinkPad T14 has a maximum brightness of 220nit, and at 25% brightness, the maximum contrast ratio is 31520:1, and at 50% or higher brightness, the contrast ratio is approximately 840:1. It has a 63% sRGB color gamut and 47% NTSC color gamut.
The laptop comes with a PM981a 512GB SSD from Samsung. This is Samsung’s SSD product for the high-end OEM market. It uses the third-generation 64-layer stacked 3D V-NAND TLC particles, and a single chip can reach a capacity of 256GB. It also integrates 512MB LPDDR4 as a cache.
In AS SSD Benchmark, this PM981a 512GB has a total score of 3685, sequential read and write exceed 2100MB/s, 1200MB/s, 4K random read 52MB/s, and random write 107MB/s.
In the CrystalDiskMark test, the sequential read and write speeds reached 3566MB/s and 2976MB/s, respectively.
The motherboard has integrated 16GB Samsung DDR4 3200MHz memory, the voltage of the memory is 1.2V, and the timing is 24-22-22-52. There is also a SO-DIMM slot for expansion.
Using AIDA64 for memory cache test, the measured read, write, and copy bandwidths were 22367MB/s, 22079MB/s, 18628MB/s, and the latency was 85.5ns.
4. Graphics performance
In the 3DMark Fire Strike Extreme test, the graphics score of the Vega7 was 971, and the operating frequency of 1600MHz was maintained most of the time during the test, and the maximum temperature was 69 degrees.
2. Final Fantasy 15 BenchMark
In the Final Fantasy 15 BenchMark test, the Ryzen 7 PRO 4750U scored 1202 in standard image quality.
3. World of Tanks
The Ryzen 7 PRO 4750U ran out of 6825 points, which is converted into a frame rate of 41FPS.
5. temperature and power consumption
1. Battery life
The laptop has a built-in lithium battery with a capacity of 50Wh. We use PCMark8 to test the office battery life. The power mode is “longer battery life”, all other processes are closed during the test, the network connection is closed, and the screen brightness is adjusted to 50%.
The ThinkPad T14 Ryzen Edition has a battery life test score of 6 hours and 45 minutes in Work Accelerated mode. This score is always at the mid-stream level in the light and thin laptop.
Use AIDA64 FPU for stress test, and the room temperature is 28 degrees during the test.
After running the AIDA64 FPU program for 15 minutes, the power consumption of the Ryzen 7 PRO 4750U stabilized at around 22W, the temperature was only 80.5 degrees, and the full core frequency was 2.65GHz.
Use FurMark to test the GPU. After 21 minutes of operation, the power consumption of the APU is 18W, the core frequency of the Vega 7 GPU can be stabilized at 1600MHz, and the temperature is only 59 degrees.
1. Rugged and durable
Open the bottom cover of the ThinkPad T14 Ryzen Edition and you can find the difference from other laptops. All its I/O ports are reinforced with alloys, which is very strong; the layout of internal components is also neat and orderly.
2. Dual heat pipes for heat dissipation
Generally, for a low-power processor with 15W TDP, at least dual heat pipes are required to control the temperature. It happens that the ThinkPad T14 fan uses a dual heat pipe heat dissipation configuration, which can maintain 22W power consumption for the processor for a long time. Under the circumstance, the temperature is suppressed to about 80 degrees, and the noise of the fan will not cause trouble.
With hyper-threading, the Ryzen 7 PRO 4750U processor has a power consumption of 22W, and its multi-threading performance is 15% better than the i7-10750H. Of course, it is 19% better than the 7 4700u processor.
Because the ThinkPad T14 Ryzen Edition uses single-channel memory by default at the factory, its gaming experience is not good. Fortunately, it has a SO-DIMM slot for expansion. If you really have a game demand, you can add another memory to form a dual channel. The game frame rate of the Ryzen 7 PRO 4750U can be increased by more than 30%. If you don’t play games, no matter whether it is 8GB or 16GB single-channel memory, there will be no impact on the experience.
