Using AMD Ryzen 7 4800U processor, Lenovo IdeaPad Slim 7 possesses extremely flexible performance compared to today’s thin and light laptops.

The test results are proving that IdeaPad Slim 7 works really well and that the processing speed of Ryzen 7 4800U is also very fast.
First of all, let’s take a look at the comparison of benchmarks of some standard laptops from Cinebench R15. For this test, all computers in the comparison measure the CPU performance from all cores when rendering 3D images.
The results of the Ryzen 7 4800U as well as the IdeaPad Slim 7 have really made a surprise when ranked 2nd in a series of familiar laptops, only slightly below the Dell XPS 15 7590 in the test. this short.
Taking a closer look at this chart, we can see that IdeaPad’s score is roughly equal to that of the Dell XPS 15 7590 with the 8-core Core i9-9980HK and the Dell XPS 15 9500 with the Core i7-10875H 8. multiply. It is worth mentioning here that the two Dell XPS models we just mentioned are not notebooks like IdeaPad, and are often chosen by people specializing in content design or video editor.
From 4th place down, devices possess a modest score compared to the top 3 we just mentioned above. More interestingly, the performance of the Ryzen 7 4700U in the Acer Swift 3 has lagged far behind the new generation. The reason is that AMD has adopted concurrent multithreading (SMT) on the 4800U chip.
Readers can also refer to the single-core performance benchmark below.
However, laptop performance will often be limited by heat, and a short test like the Cinebench R15 is not enough to judge a laptop’s true performance. We continued our testing with the Handbrake benchmark through a 30GB 1080P file encryption task. Previously, an ultrabook took more than an hour to be able to complete this task, but today’s thin and light laptops have been greatly improved.
The results of this next test are still completely beneficial for our protagonist, but different from the above, this time IdeaPad Slim 7 hasn’t left too far behind the other Ryzen brothers. .
And once again, the Lenovo IdeaPad Slim 7 also achieves roughly the same processing time as the Dell XPS, namely the 9500 XPS 15 with an 8-core Core i7-10875H processor.
Besides the CPU performance, the graphics capabilities of the AMD chip are also an issue that receives a lot of attention from users. The Ryzen 7 4800U gets one more graphics core than the Ryzen 7 4700U, and the clock speed is also slightly higher (1,750MHz vs 1,600MHz).
To add that is the Lenovo IdeaPad Slim 7 which also has LPDDR4X RAM clock up to 4,267MHz. Most Ryzen laptops right now have a DDR4 / 3200 RAM clock to save money. RAM clock speed is also a factor to enhance the graphics performance of the machine.
The next test will be a comparison of memory bandwidth between IdeaPad Slim 7 and HP Envy x340 13 with Ryzen 5, which represents notebooks with DDR4 / 3200 RAM clocks. As a result, our main character has a higher speed.
Continue to be the benchmark from 3DMark Sky Diver to sum up the performance evaluation of the machine. From there we will have a better understanding of how the Ryzen 7 4800U performs with the faster LPDD4X RAM as well as to see how the Radeon integrated graphics in Ryzen increase.
As a result, the 4800U has a huge increase in performance compared to the Radeon in the Ryzen 7 4700U. But it is also impossible not to mention other factors we just mentioned above such as: Increase the number of graphics cores, increase the clock speed, increase the CPU metric.
One more information related to this device that we want to send to readers that is Lenovo IdeaPad Slim 7 will not have a Thunderbolt 3 port according to the previous information.
All the tests above have proven that Ryzen 7 4800U on Lenovo IdeaPad Slim 7 possesses very impressive processing speed and graphics capabilities that are not inferior to other product lines.
The second purpose of this review is to help readers learn more about the AMD Ryzen 7 4800U processor before Intel launches Tiger Lake CPUs next time. This is also a line of chips that Intel targets thin and light ultrabooks.
As expected, Tiger Lake won’t beat Ryzen 4000 in multi-threaded tasks but will stand out a lot in single-threaded performance. Certainly the thin and light laptop market will be very active in the coming time, let’s wait together.
