AMD unveils roadmap for notebook processors. A few months ago, the manufacturer introduced a new appointment rule (naming conventions) processors to prioritize the range. So the first number will still define the generation, but will no longer be related to the architecture. The architecture will be represented by the number 3: 4 for Zen4 and so on. The second number refers to the Ryzen range: 3, 5, 7, 8, 9. Finally, the last number varies according to AMD, 0 is the standard number, faster versions are 5. HX suffixes for gaming/creative processors, HS for gaming/compact format and U for ultra-thin processors are still in play.

16 cores for Zen4 architecture and Ryzen 7045

The Ryzen 7045 series represents the most powerful processors in the mobile offering. They come from the desktop Ryzen 7000 and therefore combine the Zen4 architecture with 32 threads equipped with a maximum of 16 cores and 80 MB of L2 + L3 cache and can reach speeds of 5.4 GHz. They are etched in 5 nm and have a TDP of more than 55 watts. The graphics part with two RDNA2 cores is anecdotal, but in any case it will be completed with a dedicated GPU.

Performance is claimed to be up to 18% better than the Ryzen 9 6900HX in single core and up to 78% better in multitasking; It’s not surprising, because the Ryzen 9 7945HX has twice the cores and four times the cache. In-game gains range from 29 to 62%, depending on the panel of titles selected by AMD.

There are four processors in the 7045 series. The number of cores, the amount of available cache and, of course, the frequencies decrease accordingly.

3.4nm RDNA and dedicated AI unit for Ryzen 7040

The 7040 series processors, in turn, take over from the Ryzen 6000HS. These are mobile processors engraved at 4 nm and using the Zen4 architecture. The graphics part consists of 12 RDNA3 cores for the highest end, called Radeon 780M. Note that if there are sections dedicated to artificial intelligence (XDNA), AMD is quite skimpy on the specific possible uses.

The 7040 line consists of three processors. The number of cores is between 6 and 12, the amount of cache memory varies between 38 and 40 MB, and the maximum frequency reaches 5.2 GHz. TDP can vary from 35 to 45 watts depending on the integration of partners, so only HS processors. The U series with a TDP of 15-28 watts and based on the Zen4 is currently unannounced.

AMD doesn’t talk about performance. We just know that the Ryzen 9 7940HS is 34% more efficient than the Core i7-1280P and 24% more efficient than the Apple M1 Pro from 2021. On the gaming side, it would be 21% more efficient than Intel’s stated Core i7. above.

On the autonomy side, AMD announces that it can reach 30 hours in a completely improbable way, and says that this is only a prediction.

Rework for Ryzen 7035 and 7030

The 7035 and 7030 series Ryzen aren’t really new, as the 7035 series follows the Ryzen 6000 and the 7030 series follows the Ryzen 5000.

So the 7035 series takes the Zen3+ architecture announced last year, with a maximum of 8 cores and 12 RDNA2 cores per processor, all etched in 6nm.

The 7030 series is in Zen3 – the architecture launched 2 years ago – and still has a maximum of 8 cores, but is accompanied by an iGPU in Vega 8 and is carved at 7nm. The vast majority of processors that make up these two series are therefore well-known chips. This explains why AMD did not rest on the already known performance and their autonomy.

With a line of mobile processors of about 15 references, AMD has enough capabilities to easily compete with Intel. Now the battle will be played on the side of partners who, despite the arguments they put forward, are still reluctant to offer AMD processors in their laptops.
