AMD EPYC 74F3 vs AMD Ryzen 3 7440U Comparison

Head-to-Head Benchmarks

The recorded data is unambiguous: the AMD EPYC 74F3 wins every single benchmark in the head-to-head comparison, and by a wide margin. Across all six Cinebench tests, the EPYC 74F3 is consistently about 78.6% ahead of the Ryzen 3 7440U. There is not a single test where the Ryzen 3 7440U takes a win; the win count is 6 for the EPYC 74F3 and 0 for the Ryzen 3 7440U.

In Cinebench R15 multicore, the EPYC 74F3 scores 5197 against the Ryzen 3 7440U's 1112, a delta of -78.6%. The single-core R15 result follows the same pattern: 733 for the EPYC 74F3 versus 156 for the Ryzen 3 7440U, also -78.6%. The margin is so consistent across tests that it suggests a fundamental throughput advantage rather than a workload-specific quirk.

Moving to Cinebench R20, the EPYC 74F3 posts 21657 in multicore while the Ryzen 3 7440U manages 4637, again a -78.6% gap. In single-core R20, the EPYC 74F3 scores 3057 against 654 for the Ryzen 3 7440U. The same -78.6% delta appears once more.

Cinebench R23 shows the largest absolute difference. The EPYC 74F3 reaches 51566 in multicore, while the Ryzen 3 7440U scores 11042. In single-core R23, the EPYC 74F3 records 7279 versus 1558 for the Ryzen 3 7440U. Every one of these six results carries the same -78.6% delta, meaning the EPYC 74F3 delivers roughly 4.7 times the performance in each test.

The broader database context reinforces this. The Ryzen 3 7440U has an average benchmark score of 15682 and sits at the 69th percentile among all CPUs. Its nearest rival, the Intel Core i5-11400H, is only 0.4% behind, and the AMD EPYC 75F3 is 1.1% behind. The EPYC 74F3, meanwhile, has an average benchmark score of 14915 and also sits at the 69th percentile. Its nearest rivals include the Intel Core i7-9750H at 0.2% ahead and the Intel Core i3-10320 at 0.4% ahead. So while both parts occupy the same percentile tier in the overall database, their head-to-head scores are radically different because the Ryzen 3 7440U's full benchmark suite includes many PassMark tests that are absent from the EPYC 74F3's recorded results. On the six Cinebench tests where both have data, the EPYC 74F3 is dominant without exception.

The Verdict

The data points to a clear conclusion: the AMD EPYC 74F3 is the superior processor in raw compute performance across every measured Cinebench workload. The Ryzen 3 7440U does not win a single head-to-head benchmark, and the EPYC 74F3 leads by a consistent -78.6% margin in all six tests. Anyone choosing between these two strictly on benchmark results should select the EPYC 74F3.

However, the verdict is not simply "EPYC wins." The two chips serve entirely different market segments. The Ryzen 3 7440U is a mobile processor with a 28 W TDP, 4 cores and 8 threads, built on a 4 nm process with Zen 4 architecture. The EPYC 74F3 is a server and workstation processor with a 240 W TDP, 24 cores and 48 threads, built on a 7 nm process with Zen 3 architecture. The EPYC 74F3 also carries a launch MSRP of $2900. The Ryzen 3 7440U has no recorded launch MSRP in the database.

The Ryzen 3 7440U does have advantages that are not captured in the head-to-head Cinebench results. It includes integrated Radeon 740M graphics, which the EPYC 74F3 lacks entirely. It supports DDR5 memory and has a dual-channel memory bus with 89.6 GB/s bandwidth. The EPYC 74F3 supports DDR4 with an eight-channel memory bus and 204.8 GB/s bandwidth. The Ryzen 3 7440U also has a higher boost clock at 4.70 GHz versus 4.00 GHz for the EPYC 74F3, and a higher base clock at 3.00 GHz versus 2.80 GHz.

The verdict depends on the use case. For mobile computing with integrated graphics and lower power consumption, the Ryzen 3 7440U is the appropriate choice. For server or workstation workloads that demand maximum multi-threaded throughput, the EPYC 74F3 is the clear winner in the recorded data.

Where Each One Wins

The EPYC 74F3 wins every benchmark where both processors have recorded scores. That includes all six Cinebench tests: R15 multicore and single-core, R20 multicore and single-core, and R23 multicore and single-core. The consistent -78.6% delta across all six tests indicates that the EPYC 74F3's advantage is structural, driven by its 24 cores and 48 threads versus 4 cores and 8 threads, and its 256 MB of shared L3 cache versus 8 MB of shared L3 cache.

The Ryzen 3 7440U, despite losing every head-to-head test, has strengths that appear in its standalone benchmark suite. Its PassMark single-thread score is 2614, which is a meaningful result for lightly threaded workloads. It also has a PassMark multithread score of 12991, a PassMark integer math score of 36758, and a PassMark floating point math score of 20291. These numbers are not directly comparable to the EPYC 74F3 because the EPYC 74F3 has no recorded PassMark results, but they do show that the Ryzen 3 7440U is a capable mobile chip in its own right.

The Ryzen 3 7440U also has the advantage of integrated Radeon 740M graphics, making it suitable for systems that do not require a discrete GPU. The EPYC 74F3 has no integrated graphics at all, so it requires a separate GPU for any display output. The Ryzen 3 7440U's 4 nm process node gives it a manufacturing advantage in power efficiency, and its 28 W TDP is dramatically lower than the EPYC 74F3's 240 W TDP.

In terms of platform features, the EPYC 74F3 wins on memory bandwidth with 204.8 GB/s versus 89.6 GB/s, and on PCIe lanes with 128 lanes versus 14 lanes. The Ryzen 3 7440U wins on memory generation with DDR5 support versus DDR4 for the EPYC 74F3. Both support ECC memory.

Architecture Differences

The two processors come from different generations of AMD architecture. The Ryzen 3 7440U uses Zen 4 architecture with the codename Phoenix2, part of the Ryzen 3 generation. The EPYC 74F3 uses Zen 3 architecture with the codename Milan, part of the EPYC generation. This is a significant generational gap, with Zen 4 being a newer design than Zen 3.

The process nodes also differ. The Ryzen 3 7440U is built on a 4 nm process at TSMC, while the EPYC 74F3 is built on a 7 nm process at TSMC. The Ryzen 3 7440U contains 20,900 million transistors on a die size of 137 mm². The EPYC 74F3 contains 33,200 million transistors across a die size of 4x 81 mm², which is a multi-die design.

The cache hierarchies differ substantially. Both have 64 KB of L1 cache per core. The Ryzen 3 7440U has 1 MB of L2 cache per core, while the EPYC 74F3 has 512 KB of L2 cache per core. The L3 cache is the biggest difference: the Ryzen 3 7440U has 8 MB shared, while the EPYC 74F3 has 256 MB shared, a 32-fold difference. Neither processor has the 3D V-Cache option recorded.

Memory support reflects their different market positions. The Ryzen 3 7440U supports DDR5 with a dual-channel memory bus and 89.6 GB/s bandwidth. The EPYC 74F3 supports DDR4 with an eight-channel memory bus and 204.8 GB/s bandwidth. The EPYC 74F3's eight-channel configuration gives it far more memory bandwidth, which is critical for server workloads.

PCIe capabilities also differ. The Ryzen 3 7440U has Gen 4 with 14 lanes from the CPU. The EPYC 74F3 has Gen 4 with 128 lanes from the CPU. Both use PCIe Gen 4, but the EPYC 74F3 offers vastly more lanes for expansion in server platforms.

The integrated graphics situation is another major architectural difference. The Ryzen 3 7440U includes a Radeon 740M integrated GPU, while the EPYC 74F3 has no integrated graphics. This reflects the mobile focus of the Ryzen 3 7440U versus the server focus of the EPYC 74F3.
