But there is a more recent Ryzen 7 8840U
Modern mobile processors from Intel and AMD can now be compared in terms of performance not only of conventional cores, but also of NPU units for working with artificial intelligence. Tests show that Ryzen APUs win.
It’s worth mentioning right away that these are tests from AMD itself. In recent years, the company has often fairly honestly compared its solutions with competitors' products, but in such cases there is always the possibility of selecting more suitable software, which must be taken into account when evaluating the results.
In this case, AMD is focusing on running large language models locally on consumer PCs in general and processors in particular. AMD compared its Ryzen 7 7840U APU running in 15-watt mode with the Core Ultra 7 155H running in 28-watt mode. In both cases, the PCs also had 16 GB of LPDDR5-6000 RAM. It turned out that the AMD processor, which was released a year ago, is ahead of its competitor, which was released only three months ago, in all tests except one, and even in that Core Ultra is only slightly ahead. Ryzen 7 7840U relative to its competitor provides a performance increase depending on the test by approximately 10% and up to almost a twofold difference.
It is worth keeping in mind that in dry performance the Ryzen 7 7840U loses a little: 10 TOPS versus 11 TOPS. But the fresh Ryzen 7 8840U differs from the Ryzen 7 7840U only in the NPU unit, and it already offers 16 TOPS, that is, the increase relative to the Core Ultra 7 155H in reality can already exceed twofold.
