AMD Radeon 740M: Four CU RDNA 3 and Almost 50% Difference Between Laptops

The AMD Radeon 740M is the entry-level integrated graphics of RDNA 3 with four compute units. The modern architecture here does not equate to high gaming performance; based on average results from 3DMark, this iGPU is roughly on par with the older Radeon 660M and significantly trails behind the Radeon 760M and 780M. Even more critical is another fact: the performance of the Radeon 740M can differ by almost 50% across different laptops.

The Radeon 740M is used in a range of AMD Ryzen mobile processors. It has no dedicated video memory, so its speed heavily depends on the configuration of the system RAM, processor power limits, and the settings of the specific laptop.

Radeon 740M vs. 660M, 760M, and 780M

The four CU count is the main limitation of the Radeon 740M. The Radeon 760M has eight, while the Radeon 780M has twelve. The difference is clearly visible in 3DMark Time Spy Graphics.

Integrated Graphics Time Spy Graphics, average
Radeon 740M 1,430
Radeon 660M 1,450
Radeon 760M 2,260
Radeon 780M 2,657

Despite the transition from RDNA 2 to RDNA 3, the Radeon 740M does not actually outpace the Radeon 660M in this test. The newer architecture does not compensate for the smaller number of compute units.

The Radeon 760M is approximately 58% faster, while the Radeon 780M is about 86% faster. Thus, there is a much more significant performance gap between the 740M and 760M than might be inferred from their names.

Radeon 740M Performance in Real Laptops

One cannot accurately gauge a laptop's performance based solely on the designation of Radeon 740M. This is clearly demonstrated in five production models.

Device Processor RAM Time Spy Time Spy Graphics
Acer TravelMate P4 14 TMP414-42-TCO-R6KG Ryzen 5 8540U 16 GB 1,293 1,136
Lenovo ThinkPad T16 Gen 5 22AN001WGE Ryzen 5 PRO 215 16 GB 1,354 1,190
Lenovo ThinkPad L16 Gen 2 21SC0029GE Ryzen 5 PRO 215 32 GB 1,722 1,527
HP Pavilion 16-ag0057ng Ryzen 5 8540U 16 GB 1,802 1,600
Lenovo Yoga Slim 6 14APU8 Ryzen 5 7540U 16 GB 1,909 1,699

The difference between the minimum and maximum Time Spy results is nearly 48%. The disparity in Graphics performance is even greater, ranging from 1,136 to 1,699 points.

A noteworthy case is the Lenovo Yoga Slim 6 with Ryzen 5 7540U. Its Radeon 740M performs faster than in the tested systems with Ryzen 5 8540U, even though the latter has a higher maximum GPU frequency. In practice, memory bandwidth, power consumption modes, and laptop settings prove to be as critical as GPU frequency.

Therefore, it is risky to select a device based solely on the "Radeon 740M" line in specifications. Two systems with this iGPU can differ in graphical performance by almost one and a half times.

What Radeon 740M Shows in Games

One of the faster implementations of the Radeon 740M is installed in the Lenovo Yoga Slim 6 with Ryzen 5 7540U. On this system, one can evaluate the upper range of performance for this graphics chip.

Game Settings Resolution Average FPS
Counter-Strike 2 Low 1920×1080 72.7
F1 24 Low 1920×1080 41
Palworld Low 1920×1080 42
Cyberpunk 2077 Low, FSR Off 1920×1080 20.5

Counter-Strike 2 runs smoothly at Full HD on low settings. F1 24 and Palworld average around 40 FPS - playable, though there is hardly any performance headroom.

Cyberpunk 2077 demonstrates the limits of what the Radeon 740M can achieve. About 20 FPS at 1080p without FSR is insufficient for comfortable gameplay. Here, one would need to lower the resolution and use image scaling.

However, the results from the Lenovo Yoga Slim 6 cannot be automatically applied to any laptop with a Radeon 740M. As shown in the table above, a slower implementation of the GPU can lose about a third of the performance compared to this system.

Not Gaming Graphics, but Modern

The Radeon 740M supports DirectX 12 and features a modern media block with hardware AV1 support. For video playback, browsing, office applications, photo editing, and connecting external displays, its performance is adequate.

Hardware-accelerated ray tracing is also present. However, the performance of four CUs is insufficient even for heavy rasterization, so ray tracing here is more of a formal capability.

This is the primary advantage of the Radeon 740M over much simpler integrated GPUs: it is a modern graphical architecture with up-to-date multimedia capabilities, albeit with a minimal computing configuration.

Should You Choose a Laptop with Radeon 740M?

The Radeon 740M is suitable for work and study laptops where a discrete graphics card is unnecessary. It handles the system interface, video, office applications, and less demanding games without issues, and even allows for games like Counter-Strike 2 and other relatively light titles to be played at Full HD.

However, it is not wise to consider it a cheap alternative to the Radeon 760M or 780M. The four CUs seriously limit performance, and on average, the Radeon 740M is almost on par with the previous-generation Radeon 660M.

If a laptop with the Radeon 760M is only slightly more expensive, the extra cost is justified, as the performance gain is about 60%. The Radeon 740M should be chosen primarily for the price and specifications of the laptop itself rather than for gaming. It is also advisable to check benchmarks for the specific model, as differences between implementations of this iGPU can approach 50%.

Memory Bus
?
The memory bus width refers to the number of bits of data that the video memory can transfer within a single clock cycle. The larger the bus width, the greater the amount of data that can be transmitted instantaneously, making it one of the crucial parameters of video memory. The memory bandwidth is calculated as: Memory Bandwidth = Memory Frequency x Memory Bus Width / 8. Therefore, when the memory frequencies are similar, the memory bus width will determine the size of the memory bandwidth.
