CES 2023: AMD Ryzen 7000 laptops CPUs go up to 16 cores

AMD announced the upcoming release of its Ryzen 7000 mobile processors during its CES 2023 keynote. With a strong focus on performance and efficiency, these CPUs will soon arrive in some of the best gaming laptops, but AMD is not just targeting gamers.

The lineup includes processors made for all kinds of laptops, and today, AMD gave us our first glimpse at the Ryzen 7040 “Phoenix” and the Ryzen 7045 “Dragon Range.” Here’s everything you need to know about them.

Before we delve deeper into the world of these new Ryzen CPUs, let’s take a quick look at AMD’s naming scheme for this generation. It’s worth noting that not every mobile Ryzen 7000 chip will be based on the Zen 4 architecture. The second to last digit of the number reveals whether we’re looking at a Zen 2, Zen 3, Zen 3+, or Zen 4 part. This could prove to be confusing for some shoppers, although the Ryzen 7020 (Zen 2), the Ryzen 7030 (Zen 3), and the Ryzen 7035 (Zen 3+) are still new chips and aren’t part of the previous generation.

The best processors in this generation of mobility chips are the AMD Ryzen 7045-series chips. The flagship AMD Ryzen 9 7945HX comes with 16 cores, 32 threads, a massive 80MB of combined L2+L3 cache, and a clock speed of up to 5.7GHz.

In terms of performance, AMD claims that the Ryzen 9 7945HX was a whopping 78% faster than the last-gen 6900HX in productivity and multitasking, and the CPU also saw massive gains in gaming. AMD also compares the 7945HX to Intel’s Core i9-12900HX, showing off tests that put the AMD Ryzen 7045HX way ahead of Intel, ranging from an uplift of 24% to 169%. However, it’s important to note that Intel just announced its Raptor Lake mobile CPUs at CES as well.

So far, the Ryzen 7045-series consists of the following:

  • AMD Ryzen 9 7945HX — 16 cores, 32 threads, clock speeds of up to 5.7GHz, 80MB of combined cache, and a maximum TDP of 170W
  • AMD Ryzen 9 7845HX — 12 cores, 24 threads, up to 5.6GHz, 76MB of combined cache, and the same TDP as the flagship
  • AMD Ryzen 7745HX — 8 cores, 16 threads, up to 5.4GHz, 40MB of combined cache, and a TDP of 105 watts
  • AMD Ryzen 5 7645HX — 6 cores, 12 threads, a clock speed maxing out at 5.3GHz, 38MB of cache, and 105W TDP.

The AMD Ryzen 7045 range will arrive in laptops starting in February 2023, with the first five laptops being made by Alienware, Asus, and Lenovo.

Coming up next is the AMD Ryzen 7040 series, with a strong focus on being able to tackle artificial intelligence (AI) workloads while maintaining long battery life. These Zen 4 chips were built based on a 4nm process node and come equipped with RDNA 3 onboard graphics as well as AMD’s new XDNA AI engine architecture.

Set to start shipping in March 2023, the Ryzen 7040 series will consist of the Ryzen 9 7940HS, with 8 cores and 16 threads as well as clock speeds of up to 5.2GHz; the Ryzen 7 7840HS, with the same core count and a clock speed reaching as high as 5.1GHz, and lastly, the Ryzen 5 7640HS, with six cores, 12 threads, and a maximum frequency of 5.0GHz. All the parts have low power consumption, with a TDP between 35 and 45 watts.

We’re moving down to Zen 3+, which will presumably power up some more budget-friendly laptops equipped with AMD Ryzen 7035-series chips. These CPUs offer access to onboard Radeon 680M graphics, DDR5 and LPDDR5, PCIe Gen 4.0, and USB 4. AMD promises superb battery life, up to 15% longer than Intel’s Core i7-12700H, while serving up performance upgrades across the board.

Lastly, AMD is also launching some Ryzen 7030 and Ryzen 7030 Pro mobile processors, which are based on the Zen 3 architecture and a 7nm process node, equipped with up to 8 cores. The Ryzen 7030 lineup is mostly aimed at tackling productivity-related tasks, but AMD reveals that the laptops should also be able to run esports titles just fine. On the other hand, the Ryzen 7030 Pro prioritizes security and is aimed at professionals.

AMD’s mobile lineup for this generation is truly massive. While the split between Zen 4, Zen 3+, and Zen 3 can be confusing at first, it’s clear that AMD is trying to tap into as many markets as possible. The first AMD Ryzen 7000 laptops will begin to show up on the shelves in February, so it won’t take long before we’ll be able to learn more about their performance.

AMD CES 2023: Ryzen 9 7950X3D, mobile Ryzen 7000, and more
AMD CEO Lisa Su delivering AMD's CES 2023 keynote.

AMD's CES 2023 keynote is over, officially kicking off the show (although, most of the major announcements are already out of the way). Team Red had a lot to share, including Ryzen 7000X3D parts, Ryzen 7000 mobile CPUs, and new RX 7000 mobile GPUs. To catch you up, here's everything AMD announced at CES 2023.
XDNA and Ryzen 7000 mobile

AMD started off its presentation with a bit about its XDNA architecture, and critically, how it powers a new Ryzen AI engine in Ryzen 7000 mobile CPUs. AMD has a full stack available, but it highlighted the 7040 and 7045 series during its keynote. The 7040 series goes up to eight cores and 28 watts, and it's built using the same Zen 4 architecture as desktop Ryzen 7000 CPUs. In fact, it uses the same chiplet design as desktop CPUs, just in different packaging.

CES 2023: AMD’s next-gen laptop GPU could beat a desktop RTX 3060
AMD's CEO showing off the RX 7600M XT at CES 2023.

In AMD's CES 2023 keynote address, it debuted its next-generation RDNA3 mobile graphics chips, and their performance and efficiency look to be incredibly impressive. We don't have details on the entire range yet, and we want to conduct our own testing to verify performance, but AMD's bold claims leave us rather excited for the year ahead, especially when these chips are launched alongside impressive onboard GPU performance in next-generation AMD laptops.

The AMD RX 7600M XT and non-XT versions will feature up to 8GB of GDDR6 memory on a 128-bit memory bus, with support for AMD's smart power and tuning technologies, and are built on a 6nm process. AMD makes major claims about the performance of these GPUs, with the XT model reportedly able to deliver greater gaming performance than even an Nvidia desktop-grade RTX 3060 12GB. We'll need to test that ourselves to verify it, but if true, next-generation mobile gaming laptops are going to be incredibly impressive.

AMD’s new 65W processors fix Ryzen 7000’s biggest problems
Pads on the bottom of the Ryzen 9 7950X.

There's no doubt that AMD's Ryzen 9 7950X is an impressive processor, but AMD's most recent generation hasn't been off to the best start. Like it or not, AMD's latest chips are expensive, require a lot of power, and run hot. At CES, AMD is looking to correct course.

The company introduced three non-X CPUs to go alongside its big, beefy Ryzen 7000 processors, and they address the problems with the latest generation point-for-point. They're more efficient with a 65-watt power limit, but more importantly, they're far cheaper than their X-branded counterparts.
