Radeon 660M in 2026: Old RDNA 2 Graphics Still Used in New Laptops

The Radeon 660M is the integrated GPU used in AMD's budget Rembrandt-generation Ryzen 5 processors. It launched in January 2022 with Ryzen 6000 and later appeared in Ryzen 5 7535HS, Ryzen 5 7535U, Ryzen 5 130, and Ryzen 5 150 chips. In 2026, laptops with this GPU are still sold new for roughly $400-580.

Performance is close to Intel Iris Xe with 96 execution units, at around 1,500 points in 3DMark Time Spy Graphics. Dota 2 and older games run comfortably at 1080p, while demanding titles such as Cyberpunk 2077 and Baldur's Gate 3 deliver roughly 20 fps at 1080p Low without upscaling. Laptop configuration matters significantly because the 660M relies entirely on system memory bandwidth.

What's Inside and Where It Came From

The Rembrandt die is built on TSMC's 6nm process and contains 12 RDNA 2 compute units. Ryzen 7 and Ryzen 9 versions enable all 12 as the Radeon 680M. Most Ryzen 5 models use six compute units, or 384 stream processors, at up to 1.9 GHz. The Radeon 660M therefore reaches a theoretical throughput of about 1.46 TFLOPS.

The GPU has no dedicated memory and uses system RAM, typically DDR5-4800 or LPDDR5-6400. Hardware ray tracing is supported, but the available GPU performance is too low for ray tracing to be practical in modern games.

The Radeon 660M has appeared across several processor generations:

• 2022: Ryzen 5 6600U, 6600H, 6600HS, and PRO 6650U/H/HS
• 2023: Ryzen 5 7535U, 7535HS, and 7533HS
• 2025: Ryzen 5 130 and Ryzen 5 150

Most of these processors use the same six-CU Radeon 660M running at up to 1.9 GHz. The Ryzen 3 7335U and Ryzen 3 110 are exceptions: their GPUs are also called Radeon 660M but use four compute units at up to 1.8 GHz.

Neighboring Ryzen models can be easy to confuse. The Ryzen 5 7530U differs from the 7535U by only one digit in its name, but it uses older Zen 3 hardware with Radeon Vega 7 graphics. The Ryzen 5 7520U is based on a different platform and includes the much smaller Radeon 610M with two compute units.

Benchmark Performance

Radeon 660M laptops average around 1,450 points in 3DMark Time Spy Graphics, 4,575 in Fire Strike Graphics, and 230 in Steel Nomad. The Time Spy median is approximately 1,535 points, while individual laptops vary considerably depending on memory configuration and platform settings.

In Time Spy Graphics, the 660M performs close to Intel Iris Xe G7 96EU and the newer Radeon 840M. The mobile GeForce GTX 1050 remains roughly 15% faster, while the 48-EU Intel UHD Graphics used in processors such as the Core i5-13420H is around one-third slower.

In Steel Nomad, the difference between AMD's integrated GPUs is larger:

Results in Specific Devices

The difference between the lowest and highest Time Spy results is 56%. The ThinkPad L14 G5 is the clear outlier at 1,016 points. Its tested configuration uses a single 16 GB DDR5-4800 module, while the faster systems provide substantially more memory bandwidth. For an integrated GPU such as the 660M, memory configuration is an important performance constraint.

Power limits also affect results, although comparisons between different laptops include other variables such as cooling, memory, and firmware. The ASUS ExpertBook B1 operates at 15 W and trails the middle of the table by roughly 17-18%.

Above roughly 25 W, these results show little additional graphics performance. The Ninkear S14 at 25 W and ThinkPad E16 Gen 2 at 30 W differ by only 3%, while the GMK NucBox M6 mini PC with a Ryzen 5 6600H running at 50 W scores around 1,582 points.

The ThinkPad Z13 also shows that a relatively modest 22.5 W sustained limit can still produce a strong result when paired with LPDDR5-6400 memory.

Steel Nomad results require some caution because different graphics APIs can produce different scores. Three DirectX 12 results fall between 219 and 256 points, while the Chuwi CoreBook Air records 184 points using Vulkan.

What It Can Play

The following results come from the Chuwi CoreBook Air at 1080p. Its Ryzen 5 6600H operates at a 28 W sustained limit and uses 16 GB of LPDDR5-6400 memory. Its Time Spy result is close to the Radeon 660M median.

Esports titles and older games can run at 1080p with medium or high settings. More demanding games such as Baldur's Gate 3 and Cyberpunk 2077 fall to roughly 20 fps at 1080p Low, making lower rendering resolutions or FSR necessary for smoother gameplay.

At 720p, lighter titles such as Dota 2 and Strange Brigade can exceed 100 fps, although image sharpness is noticeably lower on a 1920×1200 display.

The GPU includes hardware decoding for H.264, HEVC, VP9, and AV1, which keeps CPU usage low during high-resolution video playback. Hardware AV1 encoding is not supported and arrived later with RDNA 3.

Available Devices and Prices

New laptops with the Radeon 660M mostly use the Ryzen 5 7535HS and Ryzen 5 7535U. These were typical US prices in September 2026, with some listings coming from third-party sellers:

• Manufacturer's price as of February 2026.

The Chuwi CoreBook Air is an unusual example of a new 2026 laptop still using the Ryzen 5 6600H. Despite the older processor, its LPDDR5-6400 memory configuration allows the Radeon 660M to perform close to the upper end of the normal range.

Pricing also varies considerably between configurations of the same laptop. The IdeaPad Slim 3 15ARP10 with 16 GB of RAM and a 512 GB SSD was listed at $400, while an 8 GB/256 GB configuration from a third-party seller was priced at $580.

Memory configuration deserves particular attention on 8 GB models. If the system uses only one active DDR5 memory channel, Radeon 660M performance can be substantially lower until additional memory is installed.

The used market is not always cheaper. A refurbished ThinkPad T14 Gen 3 with a Ryzen 5 PRO 6650U, 16 GB of RAM, and a 256 GB SSD was listed at around $460, close to the price of some new Radeon 660M laptops.

Competitors and Alternatives

Ryzen AI 5 340 with Radeon 840M. Graphics performance is in the same general class. Time Spy results are close, while the Radeon 840M trails the 660M by around 10% in Steel Nomad. The CPU is considerably newer, with Geekbench 6 results around 2,790 single-core and 11,200 multi-core compared with roughly 2,000 and 7,900 for the Ryzen 5 7535HS. Ryzen AI 5 340 systems also add Zen 5 CPU cores, a 4nm process, and a 50 TOPS NPU.

Ryzen 7 7735HS or Ryzen 7 170 with Radeon 680M. These processors use the same general platform generation but enable 12 RDNA 2 compute units instead of six. The Radeon 680M is around 60% faster in Steel Nomad. The IdeaPad Slim 5-15ARP G10 with a Ryzen 7 7735HS scores around 2,430 points in Time Spy Graphics and reaches 67 fps in Dota 2 at Ultra settings, compared with 49 fps for the tested Radeon 660M laptop.

Ryzen 7 8840HS or 7840HS with Radeon 780M. The Radeon 780M is roughly twice as fast as the 660M in Steel Nomad and provides substantially more headroom for modern games at 1080p.

Core i5-13420H with Intel UHD Graphics. CPU performance is competitive with many Ryzen 5 7535HS systems, but its integrated graphics score around one-third lower in Time Spy.

Ryzen 5 7530U with Radeon Vega 7. This processor often appears in the same price range as Ryzen 5 7535U systems, but its integrated graphics are around 30% slower in Steel Nomad and are based on an older GPU architecture.

Verdict

The Radeon 660M is a six-CU RDNA 2 integrated GPU introduced in 2022 that remains in new laptops in 2026. Its performance is close to Intel Iris Xe G7 96EU and the Radeon 840M, with a typical Time Spy Graphics score of around 1,500 points.

It is fast enough for desktop applications, 4K video playback, esports titles, and many older games at 1080p. More demanding games such as Cyberpunk 2077 and Baldur's Gate 3 run at roughly 20 fps at 1080p Low without upscaling.

Memory configuration has a large effect on real-world performance, so Radeon 660M laptops with adequately configured DDR5 or LPDDR5 memory can perform much better than otherwise similar systems with limited memory bandwidth.

At current prices, the 660M competes not only with older Intel and AMD integrated graphics but also with newer Radeon 840M laptops. Radeon 680M and 780M systems remain substantially faster for gaming, while newer Ryzen AI platforms provide similar entry-level graphics performance with much faster CPUs.
