After fits and starts in a years-long effort to make its máy tính CPUs more competitive with Intels, AMD on Monday offered the first detailed look its most ambitious step yet: the Ryzen 4000 series.

About Tom Brant
Unveiled CES in January, Ryzen 4000 chips are the first máy tính-specific ones from AMD to be based on the companys latest 7-nanometer production process. AMD claims the new chips, codenamed “Renoir,” will offer better computing and graphics performance than both previous-generation Ryzen máy tính chips as well as many Intel Core CPUs.
These advances are thanks mostly to the power efficiencies of the Zen 2 architecture, AMD says. A Renoir chip will offer approximately twice the performance for each watt of power it consumes compared with previous generations, according to Jason Banta, AMDs general manager for OEM solutions.
Power efficiency has been a weak spot in previous AMD processors, especially those in ultraportable laptops. Thats partly why Intel chips have long dominated the market, relegating AMD to fill niches with one-off designs like the Microsoft Surface Edition Ryzen CPU, available only in the 15-inch Microsoft Surface Laptop 3.
Ryzen 4000 chips also have integrated Radeon graphics processors, so they can be used in ultrathin laptops that arent designed for gaming and therefore dont require bulky, expensive, power-hungry discrete GPUs. Some máy tính models with Ryen 4000 CPUs have already been announced, including two special-edition gaming models from Asus and Dell that were unveiled CES. Ultimately, AMD is expecting more than 100 models to launch this year, including more than a dozen by the end of the month.

To broaden the appetite for Renoir chips beyond their higher performance capabilities, AMD says it is also stepping up its quality control and partnership efforts with major máy tính vendors.
Once the [laptop] is designed, were also looking to make sure its perfect as it goes out the door, Banta said a press briefing last month. The company now has validation laboratories set up its facilities in Austin, Texas, and Shanghai, where workers will resolve issues with hardware driver and operating system updates before theyre pushed automatically to consumers laptops.
H Series vs. U Series
The most powerful Ryzen 4000 chips will show up in large, bulky gaming laptops and workstations. Among these models, identified by an H in their model names, is the flagship Ryzen 9 4900HS, an additional chip that AMD announced on Monday. Its an eight-core, 16-thread behemoth with a 3GHz base clock speed and a 4.3GHz boost clock speed. Its closest competitor is the Intel Core i9-9880HK, also an eight-core chip, which is available in the Apple MacBook Pro 16-Inch.

Other previously announced H-series chips include the eight-core Ryzen 7 4800H and the six-core Ryzen 5 4600H. Aside from core count and the Ryzen 5 4600Hs slightly lower base clock speed, the main difference between these two chips are their Radeon graphics silicon: the Ryzen 7 4800H has seven graphics cores with a frequency of 1.6GHz, and the Ryzen 5 4600H has six graphics cores with a frequency of 1.5GHz.
AMD Ryzen 4000 Laptop Processors
While H-series chips are intended to operate 45 watts (their thermal design power rating, or TDP) some laptops will have versions with a 35-watt TDP. They’ll be designated with an “HS” in the model name. The first such máy tính is the AsusROG Zephyrus G14, pictured above.
While these H-series chips are the most powerful of the bunch, theyre overkill for the ultraportable laptops that make up the bulk of the market and are crucial to Renoirs success. So the majority of the new Ryzen 4000 chips will be part of the U series, which consume even less power, with TDP ratings of 15 watts or 25 watts.
The flagship U-series chip is the Ryzen 7 4800U, which has the same number of cores and threads as the Ryzen 9 4900HS. The key difference (other than reduced power consumption) is clock speed: the Ryzen 7 4800U can run as slow as 1.8GHz during light workloads, almost three times slower than the Ryzen 9 4900HS.
Other U-series chips include a second eight-core Ryzen 7 without multithreading tư vấn, so it can only handle eight instruction threads instead of 16. Multithreading can make modern software run faster, since each core can handle two instruction sets the same time, instead of just one.
There are also two six-core Ryzen 5 chips, and a quad-core Ryzen 3.
Better Performance, in Most Cases
What kind of performance can you expect if you buy a flagship ultraportable máy tính with a Ryzen 7 4000-series chip instead of a Intels latest 10th-generation Core i7? According to AMDs internal performance tests, the Ryzen 7 4700U is 36 percent faster than the Core i7-10510U encoding a video using the Handbrake app. Its also 24 percent faster rendering an image in Blender, and 39 percent faster performing digital content creation as measured by the PCMark 10 benchmark.
The new Ryzens also appear to have some advantages when it comes to gaming, though it depends on the title. AMD says the Ryzen 7 4800U was able to achieve 108 frames per second (fps) while playing Counter Strike: Go compared with 69fps for the Core i7-10510U. But performance on Fortnite is tied, 62fps.
The same types of performance differences are true of productivity tasks as well. The Ryzen 7 is about 10 percent faster on the PCMark 10 overall benchmark, though it performed slightly worse than the Core i7 while running Microsoft Office applications in AMDs tests.
We havent been able to corroborate these results, since Ryzen 4000-series laptops arent shipping yet, but benchmark results that leaked earlier this year appear to tư vấn least some of AMDs claims.
All-Day Battery Life
Other than performance, battery life is one of the key requirements for many máy tính shoppers, and its something that AMD says it has greatly improved with Renoir. Previous AMD chips werent well-optimized to take advantage of times when the máy tính doesnt require as much power, such as when its asleep or during low-power activities like typing an email.
In AMDs previous Ryzen 3000 Picasso generation, for instance, the laptops operating system can only see a single chip power state, according to Dan Bouvier, AMDs chief architect for client systems. Renoir chips have a redesigned configuration and power interface with three distinct states, which means the operating system can better communicate to the chip exactly how much power is required for a given task.
While measuring battery life is notoriously difficult, AMD is confident that these and other improvements will help a typical Ryzen 7 4800U-powered máy tính achieve a battery life of 11 hours under what it considers typical use scenarios. Thats longer than Intels Project Athena standard, which requires laptops that are certified under it to last for 9 hours of typical use.
Ryzen 4000 for the Win?
AMDs Ryzen desktop processors have picked up favorable reviews from both consumers and the truyền thông. The companys high-end Ryzen 9 and Ryzen Threadripper models in particular have offered exceptional performance reasonable prices, and prompted a fair bit of hand-wringing Intel, which last year drastically reduced the prices of its high-end consumer CPUs to stay competitive.
With máy tính processors, however, AMD still has a lot of catching up to do. Will Ryzen 4000 be enough to cement AMD as a reasonable competitor to Intel in the far more important mobile chip market?
Well have to wait until we test a Ryzen 4000 máy tính to find out. Widespread disruption to the technology supply chain in China from the new coronavirus could result in delays to the production of new máy tính models. AMD expects the impacts to be modest, however, and it is sticking with the projections it first made in January that 100 laptops with Ryzen 4000 chips will be available for sale worldwide by the end of the year.
