The Ryzen 7 4800U is an Absolute Monster: Lenovo Yoga Slim 7 14 Laptop Review
The star of the Lenovo Yoga Slim 7 is indubitably its Ryzen 7 4800U APU. Aside from a few neck-to-neck single-threaded tests, there is no benchmark or game where the new AMD processor doesn’t come out on top over the best that the Intel Iris Plus G7 or Comet Lake-U series currently have to offer. We’re not even talking thin margins; raw CPU multi-thread and graphics performance can be 40 to 50 percent faster than the Core i7-10710U and Core i7-1065G7, respectively, all while consuming just a few Watts more. Users get the best of both worlds — the GPU performance of 10 nm Ice Lake and the multi-thread CPU performance of 14 nm Comet Lake-U — in one faster and more power-efficient 7 nm 8-core package.
The challenge for AMD now is to offer a consistent level of processor performance across multiple models and OEMs. The Yoga Slim 7 is supposed to show the Ryzen 7 4800U at its best which means that future laptops may run this same processor at slower speeds. It will be interesting to see just how wide of a performance gap there will be between different laptops equipped with the same Ryzen 7 4800U APU especially since we’ve already recorded huge performance gaps between 10th gen Ice Lake systems. In other words, the last thing we want to see is a Ryzen 7 4800U laptop running 40 or 50 percent slower than our Yoga Slim 7 especially when subjected to prolonged stress.
As for the Lenovo laptop itself, it’s essentially an enlarged IdeaPad S940. We suspect that it couldn’t be the exact same size as the IdeaPad S940 because Lenovo wanted the extra volume and thus cooling potential to fully exploit the 25 W octa-core CPU. Either way, this means that the Yoga Slim 7 will be slightly heavier than most 14-inch subnotebooks in the market.
There are a few other oddities and drawbacks to the chassis. The lack of a webcam shutter, for example, has us bewildered especially when the cheaper IdeaPad S340 has one. The display is not as bright as on the IdeaPad S940 and many other flagship Ultrabooks for that matter. Still, we can appreciate the dual storage bays and FreeSync compatibility which other subnotebooks do not usually offer.
