New AMD laptop CPU destroys its predecessor, winning by 90%

New benchmarks suggest that there’s a lot to be excited about if you’re a laptop gamer. The leaked tests show off the performance of the upcoming AMD Ryzen 9 7845HX, as well as AMD’s latest Ryzen 7040 laptop APU.

The former completely destroyed its predecessor, while the latter proved itself to be a strong alternative to a traditional gaming laptop — perhaps even better than Valve’s Steam Deck.

AMD has a whole lot of new mobile processors set to come out soon, including two lineups of laptop CPUs, as well as new APUs. Today’s benchmarks give us a glimpse into the performance of AMD Ryzen 7045 Dragon Range (enthusiast laptop processors) and AMD Ryzen 7040 Phoenix (the latest APUs).

Let’s start with the 12-core, 24-thread beast that is the Ryzen 9 7845HX, which has a maximum clock speed of 5.2GHz and a TDP that can go above 55 watts. The CPU will soon be found in laptops such as the Alienware M16/M18 or the Lenovo Legion. It’s not quite the best processor in the lineup — that title belongs to the Ryzen 9 7945HX with 16 cores and 32 threads. Regardless, both chips are said to be intensely powerful, and they have the highest core counts ever seen in an AMD laptop chip.

The Ryzen 9 7845HX was tested in PassMark, and as seen above, it’s the fastest chip in the database by far right now. This might change when the Intel Raptor Lake flagship arrives — the Core i9-13980HX is most likely going to be the top laptop processor of this year.

For now, AMD’s Ryzen 9 7845HX reigns supreme with a whopping 46,791 points in the multi-core test and 4,003 points in single-core. This makes it 90% faster in multi-threaded tasks and 17% faster in single-core operations compared to the Ryzen 9 6900HX. Keep in mind that these scores are based on a single benchmark, so the real result might be less impressive, but we’re still looking at massive gains here.

The upcoming Ryzen 7040 APU was tested too, this time by 3DMark Time Spy, and it showed off some rather surprising graphics performance thanks to the updated RDNA 3 technology. It’s equipped with 768 shader cores and can hit clock speeds of up to 2.9GHz in boost mode. That makes it better than the GPU found in the Steam Deck, which belongs to the last-gen RDNA 2 family and sports 512 shader cores.

These numbers translate to better benchmark scores, as shared by Tom’s Hardware. The new AMD APU scored around 3,000 points versus 1,700 for the Steam Deck graphics solution. That’s a huge gain, but we have to keep in mind that the Steam Deck runs a much smaller screen than a typical laptop will. Steam Deck only has a resolution of 1,280 x 800, while the APU will be found in laptops that are at least 1080p.

Most gamers will still aim to buy one of the new laptops with Ryzen 7045 chips instead of the Phoenix APU, but if you want a balanced and lightweight device, it seems that the use of RDNA 3 graphics gave the Ryzen 7040 a huge boost that might make it more than adequate for some less-demanding games. The Ryzen 9 7845HX makes a strong alternative for pure gaming laptops. However, both lineups will soon face fierce competition from Intel, so things are about to heat up.

AMD’s new GPU could bring PS5 Pro-like performance to laptops
Cyberpunk 2077 running on the Asus ROG Zephyrus G14.

AMD has quietly launched the Radeon RX 7800M GPU built on the current RDNA 3 architecture for gaming laptops. This GPU is designed to bring desktop- and console-level gaming experiences to portable laptops. What’s particularly intriguing about the RX 7800M is its close resemblance to the newly revealed PlayStation 5 Pro, which is thanks to a similar spec sheet that allows it to deliver comparable performance in a portable form factor.

The latest laptop graphics card is based on the Navi 32 GPU architecture and comes with 12GB of 18Gbps GDDR6 VRAM, likely utilizing a 192-bit memory bus and offering a total memory bandwidth of 432GB/s. It includes 48MB of Infinity Cache and is equipped with 60 Compute Units (CUs), 90 Render Output Units (ROPs), and a thermal design power (TDP) of up to 180 watts. The card runs at a frequency of 2.145GHz and supports popular video rendering formats like H264, H265, and AV1.

AMD may have transformed this thin and light laptop into a gaming powerhouse

AMD has a new driver for its latest Ryzen AI 300 processors, and it introduces a feature that could provide a massive performance boost in games. It's called Variable Graphics Memory, or VGM, and it allows the integrated graphics to convert up to 75% of the memory in a system to dedicated graphics memory. This, according to AMD, can not only boost performance in games, but also make some otherwise unplayable titles boot.

The new Ryzen AI 300 processors are mostly found in thin and light laptops, including devices like the Zenbook S 16 that aren't targeted at gamers. In addition to VGM in the new driver, AMD also turned on its Fluid Motion Frames 2 (AFMF 2) feature for Ryzen AI 300 processors. With both features working in tandem, you can see the performance boost on the Zenbook S 16 below.

AMD’s new CPU could silently replace the Ryzen 7 7800X3D
The AMD Ryzen 5 7600X3D CPU.

AMD just expanded its lineup of gaming CPUs, but it's not a Zen 5 chip. Instead, AMD launched a new Zen 4 CPU, the Ryzen 5 7600X3D. Once again a Micro Center exclusive, the CPU could be an interesting budget offering ... if not for the fact that it still costs a pretty penny. Meanwhile, the Ryzen 7 7800X3D seems to be disappearing from the market. What's going on?

The fact that AMD revisited the Zen 4 lineup is not surprising, as it still continues to release Zen 3 chips. It's also not shocking that the Ryzen 5 7600X3D is a Micro Center exclusive, as the Ryzen 5 5600X3D was also only available at that one retailer. In the case of the 7600X3D, though, it'll also be available in Germany through Mindfactory.
