On Thursday, October 26, AMD revealed its eighth-generation APU lineup along with the first three laptops that will rely on these chips. Short for accelerated processing unit, the latest APUs are all-in-one chips camming AMD’s new Ryzen processor cores and its new Vega graphics cores together into one solution. Right now, there are only two processors in the new eighth-generation family slated to arrive before the end of 2017.

Here are the specifications of the new Ryzen APUs:

AMD’s new APUs follow the company’s seventh-generation “Bristol Ridge” chips released in the middle of 2016. The new APUs promise up to 200 percent more CPU performance than the Bristol Ridge generation, up to 128 percent more graphics performance, and up to 58 percent less power consumption. The Ryzen cores are based on AMD’s new “Zen” CPU core design that was built from scratch to generate higher performance on a lower power draw, and a lower price tag.

If you’re looking for gaming on the go, laptops with these two new APUs can provide decent framerates without a secondary discrete GPU. AMD says the Vega cores can generate an average rate of 43 frames per second in Quake Champions using a 1,280 x 720 resolution and high graphics settings. The chips can also manage an average of 66 frames per second in Overwatch (1,280 x 720 / low), and 59 frames per second in League of Legends (1,920 x 1,080 / medium).

The two new APUs include AMD’s new SenseMi technology suite that adjusts the APU’s power consumption per workload so it’s not constantly draining your battery. This suite also includes an updated, second-generation Precision Boost component that will adjust the clock speed when needed in 25MHz increments using a new algorithm. This component provides the highest possible speed to achieve the maximum performance in games and other heavy workloads.

According to AMD, the new APUs are capable of boosting their performance beyond their out-of-the-box boost speed with the proper cooling system installed (aka Mobile XFR). That means you may see “overclocked” chips served up in certain laptops. Artificial intelligence is baked into each Ryzen core for mapping power and consumption for better application behavior.

Finally, in the 3DMark Time Spy benchmark, AMD shows that its Ryzen 7 2700U APU outperforms the GeForce GTX 950M discrete graphics chip and Intel’s Core i7-7500U processor for laptops. Ultimately, the bottom line is that AMD is targeting desktop performance for ultra-thin laptops using a thin, all-in-one processor solution that shouldn’t break your wallet in the end.

Here are the first three laptops sporting AMD’s new APUs:

Don’t wait for new GPUs. It’s safe to buy a gaming laptop now
Upcoming Nvidia RTX 40-series laptops over a black and green background.

If you've been planning to buy a gaming laptop, it seems that it might be best to shop now instead of waiting for new hardware. Although rumor has it that Nvidia might soon launch three new desktop GPUs, it appears that those graphics cards are unlikely to appear in laptops anytime soon. Is there any point in waiting for the RTX 40-series refresh if you're a laptop user? For various reasons, most likely not.

Various leakers have been sharing information about the rumored RTX 4070 Super, RTX 4070 Ti Super, and RTX 4080 Super for a while now. Considering that Nvidia is planning to deliver a "special address" at CES 2024, the general assumption is that this is when the company will officially announce the RTX 40-series refresh.

AMD is valiantly keeping its word to gamers
Someone holding the Ryzen 7 5800X3D in a red light.

AMD's aging AM4 platform has been around since 2016, and it's a socket that AMD has promised to support for "for many years." We thought we'd waved goodbye to AM4 for good, but a new leak says that AMD has two new 3D V-Cache chips in the works, namely the Ryzen 7 5700X3D and the Ryzen 5 5500X3D. If the rumor is to be believed, AMD may not be done with AM4 yet, which is great news for those hoping not to have to upgrade their entire PC just to get the latest performance.

As per the user @g01d3nm4ng0 on Twitter, the new chips will serve up the same massive L3 cache we've come to expect from AMD's X3D chips, making them solid options for gamers on a tighter budget. No one expected that AMD would keep releasing new versions of last-gen chips well over a year since the launch of the Ryzen 7000, and yet, it seems that they're in the works.

Gigabyte may have just leaked AMD next big release
AMD Ryzen 5000G.

Gigabyte has just sparked some rumors about the next generation of AMD's top processors, perhaps accidentally leaking the release date that AMD itself hasn't talked about just yet. Then again, coming from Gigabyte, it can be considered a fairly credible source. In any case, AMD's next-gen APUs seem to be right around the corner, serving up graphics powers far beyond anything we've seen in an integrated GPU so far.

We're talking about AMD's 8000G APUs, which are a much-anticipated update to the company's lineup. So far, the best APU available to desktop users is the Ryzen 7 5700G, featuring RDNA 2 graphics. With the release of the Ryzen 8000G Phoenix, AMD will move to the RDNA 3 architecture, delivering up to 12 RDNA 3 compute units (CUs) in the rumored Ryzen 7 8700G. That's the same number of CUs as in the RX 6400.
