AMD Ryzen 3 7440U
The Ryzen 3 7440U is an oddball Phoenix family processor (APU) that has one Zen 4 core and three Zen 4c cores working together. This lower mid-range chip saw the light of day in H1 2023; it offers 8 threads, since all of the cores are SMT-enabled, and a base clock speed of 3.0 GHz. The highest Boost clock speed that a 7440U can run at is 4.7 GHz.
Unlike its faster and costlier brethren, this Ryzen 3 series chip features the Radeon 740M integrated graphics adapter instead of the more powerful 760M or 780M options. It also comes with no Ryzen AI support.
Architecture & Features
Phoenix family chips are powered by the Zen 4 architecture, much like Dragon Range family chips are. Zen 4 introduces some rather solid AVX512 support (which Zen 3 chips did not have) and, thanks to a plethora of other improvements including larger caches/registers/buffers across the board, is set to bring a double-digit IPC improvement.
The 7440U has 8 MB of L3 cache and support for various flavours of DDR5 RAM, up to DDR5-5600 and LPDDR5x-7500. It is compatible with USB 4 and thus with Thunderbolt; PCI-Express support is limited to the 4.0 spec which means speeds up to 7.8 GB/s are possible provided a fast NVMe SSD is used. There is no Ryzen AI functionality here which is, much like replacing full-fat Zen 4 cores with more compact Zen 4c cores, a way for AMD to get the costs down.
OS support is limited to 64-bit Windows 11 and Windows 10 editions and of course to Linux. The chip is not overclockable, and neither can you replace it with a faster one as it gets soldered down for good (FP7 or FP7r2 socket interface).
Performance
While we have not tested a single system built around the 7440U as of late 2023, it's safe to expect the chip to be about as fast as hexa-core Ryzen 4000U options (these are powered by Zen 2) such as the Ryzen 5 4600U, as far as multi-thread performance is concerned.
Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.
Graphics
The Radeon 740M has 4 CUs (256 shaders) purring away at up to 2,500 MHz. This iGPU will let you connect up to four SUHD 4320p monitors and it is capable of both decoding and encoding most video codecs including AVC, HEVC and AV1. Its gaming performance is fairly unimpressive, as of late 2023; running simpler titles such as CS:GO in resolutions such as HD 720p is the best it can do for you.
Power consumption
This Ryzen 3 series chip has a long-term power limit (default TDP) of 28 W that laptop makers are free to tune. Values between 15 W and 30 W are possible; most companies will probably go for a higher value to get higher performance.
The 7440U is built with TSMC's 4 nm* process for high, as of late 2023, energy efficiency.
