AMD introduces processors for budget laptops and flagship gaming PCs


What is happening

At Computex 2022, AMD is showcasing a new generation of desktop processors, initially targeting gamers, and a new laptop processor aimed at laptops costing between $399 and $699.

why is it important

Cheaper laptops with fewer trade-offs are still in demand, and new PC processors promise more than the usual performance boost from generation to generation, as well as support for certain technologies that can improve speed and smoothness. gameplay.

And after

We’ll learn more about these developments over the next few months before they launch closer to October.

During her keynote for Computex 2022, Lisa Su, CEO of chip giant AMD, previewed the new products and technologies we can expect to see debut in the coming months and head into the rest. from 2022. They include the long-teased next-gen Ryzen 7000 series of 5nm desktop processors – codenamed “Rafael” – and accompanying platform architecture, as well as new Ryzen processors (named code “Mendocino”) for budget laptops and Chromebooks costing between $399 and $699.

New budget mobile processors aren’t seismic news, but the products they drive are the ones people are looking for. In this case, AMD will replace its low-end Ryzen mobile chips for Windows laptops and Chromebooks, apparently updates to the Ryzen 3 5425U and 5425C (although AMD hasn’t specified, not specified the name of the lines ), most notably with RDNA 2 integrated graphics and some of the new power-saving technologies that will allow laptops to meet AMD’s target of 10 hours of battery life in mixed use. The move to RDNA 2 alone should provide a noticeable improvement to these laptops.

Next generation PC processors

AMD has dropped a little on its upcoming Zen 4 architecture at CES 2022and today offered plenty more details – including that it appears to be on track for the second half of this year.

Zen 4 is based on dual 5nm chiplets containing the space-sharing CPU cores with a 6nm supporting chipset that adds an integrated GPU based on its RDNA 2 architecture – recently incorporated into its Ryzen 6000 mobile processors – that can output HDMI 2.1 and DisplayPort 2. It also catches up Intel with support for DDR5 memory, Wi-Fi 6E and up to 24 lanes for storage and graphics from state-of-the-art PCIe Gen 5 slots.

The cores have twice the L2 cache (1MB per core) and an expanded instruction set to enable greater AI acceleration. AMD claims that all of this results in a more than 15% increase in single-core performance and allows it to reach a maximum boost frequency of over 5GHz. Although it has narrowed the gap considerably, AMD still tends to lag Intel for single-core speed, which applications tend to use for heavy processing during short bursts.

There’s no PCIe 5 NVMe SSD yet, but AMD says at least Crucial should have one ready when new motherboards launch in the fall.

Speaking of motherboards, the Ryzen 7000 uses a new socket, AM5, which has a higher pin count than AM4, as well as native support for CPU power consumption of 170 watts (AM4 is 142 watts) . A disadvantage of the new architecture: it does not support DDR5, only DDR4. Since DDR5 is always more expensive than DDR4, that means you can’t configure cheap and wait for prices to drop to upgrade.

AMD

The motherboard chipsets will come in three flavors, just as they do today: An X670 Extreme for control freak overclockers, with PCIe 5 throughout; X670 with based overclocking, at least one PCIe 5 m.2 NVMe and optional PCIe 5 slot for graphics card; and a mainstream B650, which only has PCIe 5 for the m.2 SSD. Motherboards for the first wave of systems will come from the usual suspects, ASRock, Asus, BioStar, Gigabyte and MSI.

Faster storage

The company also announced a new addition to its repertoire of “smart” gaming laptops, SmartAccess Storage, which incorporates support for Windows 11. Direct storage — the technology used by the Xbox series X and S – to speed up the loading of games and game resources from an SSD by performing texture decompression on the graphics chip and providing the GPU with direct access to system memory (SmartAccess Memory), allowing it to take a faster path to graphics memory rather than the usual long path through the CPU.

It joins SmartShift Max, which can mix power as needed between CPU and GPU in supported games to maximize speed where you need it most and SmartAccess Graphics, which intelligently switches the display connection between integrated and discrete GPUs (a handy change that uses less power than typical hybrid graphics design), plus SmartShift Eco, which can automatically switch between the two GPUs when it detects you’ve disconnected your AC adapter.

It all goes into a laptop that AMD is dubbing AMD Advantage, which, like Intel’s Evo brand, means it uses the latest AMD chips and technology. This summer, Corsair will launch a new AMD Advantage laptop, which AMD says is the first optimized for streaming, the Corsair Voyager. “Optimized” means it incorporates Elgato’s (Corsair owned) streaming technology with software and 10 dedicated keyboard keys to emulate a Stream Deck and FHD webcam plus software based on the Elgato face camera. You will be able to purchase custom versions of the Voyager through Origin PC (also owned by Corsair).
