AMD EPYC 7702P vs AMD Ryzen 3 7440U Comparison

The Verdict

The data in this comparison presents one of the most lopsided matchups in the database. The AMD EPYC 7702P wins all six head-to-head benchmark comparisons, with the Ryzen 3 7440U trailing by roughly 79% in every single test. The EPYC 7702P delivers a Cinebench R23 multi-core score of 52,308 against the Ryzen 3 7440U's 11,042, a 78.9% deficit for the mobile chip. Even in single-core tests, where the Ryzen 3's higher boost clock might suggest an advantage, the EPYC 7702P leads by the same margin, scoring 7,384 versus 1,558 in Cinebench R23 single-core.

The verdict is straightforward: the EPYC 7702P is the choice for any workload that scales with core count, thread count, or memory bandwidth. Its 64 cores and 128 threads, eight-channel DDR4 memory, and 256 MB of shared L3 cache make it a server-class part. The Ryzen 3 7440U, with 4 cores and 8 threads, is a mobile processor designed for efficiency and portability. The Ryzen 3 7440U should be selected by users who need a compact, low-power solution with integrated graphics and modern DDR5 memory support. The EPYC 7702P should be selected by anyone running heavily threaded server workloads, virtualization, or data-center applications where raw throughput dominates.

Both processors sit at the 69th percentile in the database, meaning their average benchmark scores place them in the same tier relative to all CPUs. However, that percentile parity masks the fact that the EPYC 7702P's average benchmark score of 15,130 is close to the Ryzen 3 7440U's 15,682. The nearest rivals for each part confirm this odd pairing: the Ryzen 3 7440U trades blows with the Intel Core i5-11400H (0.4% difference) and AMD EPYC 9254 (0.5% difference), while the EPYC 7702P sits near the Intel Core i3-1315U (0.7% difference) and AMD EPYC 74F3 (1.4% difference). These are different performance classes that happen to land at the same percentile.

Architecture Differences

The Ryzen 3 7440U and EPYC 7702P represent two completely different design philosophies from AMD. The Ryzen 3 7440U is built on the Zen 4 architecture with the codename Phoenix2, manufactured on TSMC's 4 nm process node. It packs 20,900 million transistors into a 137 mm² die. The EPYC 7702P uses the older Zen 2 architecture with the codename Rome, built on TSMC's 7 nm process node, with 3,800 million transistors on a 74 mm² die. The transistor density difference is stark: the Ryzen 3 crams more than five times as many transistors into a die that is less than twice the size.

The core configurations could not be more different. The Ryzen 3 7440U has 4 cores and 8 threads, while the EPYC 7702P has 64 cores and 128 threads. This 16x difference in core count and thread count explains the massive multi-core performance gap. The cache hierarchy also differs significantly. The Ryzen 3 7440U has 64 KB of L1 cache per core, 1 MB of L2 per core, and 8 MB of shared L3. The EPYC 7702P has 96 KB of L1 per core, 512 KB of L2 per core, and a massive 256 MB of shared L3 cache. The EPYC's L3 cache is 32 times larger than the Ryzen 3's.

Memory architecture is another fundamental split. The Ryzen 3 7440U supports DDR5 memory over a dual-channel bus with 89.6 GB/s of memory bandwidth. The EPYC 7702P supports DDR4 memory over an eight-channel bus with 204.8 GB/s of memory bandwidth. Both support ECC memory, but the EPYC's eight-channel configuration gives it more than double the memory bandwidth of the Ryzen 3. The PCIe support also differs: the Ryzen 3 offers Gen 4 with 14 lanes (CPU only), while the EPYC offers Gen 4 without a lane count specified in the database.

The Ryzen 3 7440U includes an integrated Radeon 740M GPU, making it suitable for systems without a discrete graphics card. The EPYC 7702P has no integrated graphics, which is typical for a server processor where a separate management or display controller handles video output. The Ryzen 3 is classified as a mobile part using AMD Socket FP7, while the EPYC uses AMD Socket SP3 for server and workstation platforms. The Ryzen 3 was released on 2023-05-02, while the EPYC 7702P was released on 2019-08-06, a gap of nearly four years.

Specification Differences

The specification table reveals the core differences between these two processors. The Ryzen 3 7440U has 4 cores and 8 threads, while the EPYC 7702P has 64 cores and 128 threads. The Ryzen 3 has a base clock of 3.00 GHz and a boost clock of 4.70 GHz, while the EPYC has a base clock of 2000.00 MHz (2.00 GHz) and a boost clock of 3.35 GHz. The Ryzen 3's higher clock speeds are offset by the EPYC's far greater core count.

Power consumption shows the mobile versus server split: the Ryzen 3 7440U has a TDP of 28, while the EPYC 7702P has a TDP of 200. The Ryzen 3 uses AMD Socket FP7, the EPYC uses AMD Socket SP3. The process node differs: 4 nm for the Ryzen 3 versus 7 nm for the EPYC. Cache configurations differ in every level: L1 is 64 KB per core versus 96 KB per core, L2 is 1 MB per core versus 512 KB per core, and L3 is 8 MB shared versus 256 MB shared.

Memory support diverges completely. The Ryzen 3 uses DDR5 over a dual-channel bus with 89.6 GB/s bandwidth. The EPYC uses DDR4 over an eight-channel bus with 204.8 GB/s bandwidth. Both support ECC memory. PCIe support is Gen 4 for both, but the Ryzen 3 has 14 lanes (CPU only) while the EPYC's lane count is not specified. The Ryzen 3 has integrated Radeon 740M graphics, the EPYC has none. The Ryzen 3 is a mobile part, the EPYC is a server/workstation part. The Ryzen 3's part numbers are 100-000001068(FP7r2) and 100-000001071(FP7), while the EPYC's part number is 100-000000047. Neither processor has an unlocked multiplier.

Head-to-Head Benchmarks

The head-to-head benchmark data is remarkably consistent. The EPYC 7702P wins all six recorded comparisons, and the margin is nearly identical across every test. In Cinebench R15 multi-core, the EPYC scores 5,272 against the Ryzen 3's 1,112, a 78.9% lead. In Cinebench R15 single-core, the EPYC scores 744 against the Ryzen 3's 156, a 79% lead. The single-core margin is slightly larger, which is notable given the Ryzen 3's higher boost clock.

Cinebench R20 multi-core shows the EPYC scoring 21,969 versus the Ryzen 3's 4,637, again a 78.9% lead. Cinebench R20 single-core has the EPYC at 3,101 and the Ryzen 3 at 654, a 78.9% lead. Cinebench R23 multi-core, the most demanding of the Cinebench tests, shows the EPYC at 52,308 and the Ryzen 3 at 11,042. Cinebench R23 single-core shows the EPYC at 7,384 and the Ryzen 3 at 1,558. The consistency of the 78.9% delta across all tests suggests a systemic performance advantage rather than a workload-specific one.

The Ryzen 3 7440U has zero wins in the head-to-head comparisons. However, the database also records additional benchmark scores for the Ryzen 3 that are not part of the head-to-head set. In Geekbench, it scores 5,806 multi-core and 2,003 single-core. In PassMark tests, it reaches 15,689 for data compression, 9,215 for data encryption, 10,356 for extended instructions, 20,291 for floating point math, 36,758 for integer math, 12,991 for multithread, 21,479 for random string sorting, and 2,614 for single-thread. The EPYC 7702P has no recorded scores in these additional tests, so the database does not show how they compare outside the Cinebench suite.

The average benchmark scores tell a different story than the head-to-head results. The Ryzen 3 7440U has an average benchmark score of 15,682, while the EPYC 7702P has an average of 15,130. This means the Ryzen 3 actually scores slightly higher on average across all recorded benchmarks, despite losing every head-to-head Cinebench test by a wide margin. This apparent contradiction is explained by the fact that the Ryzen 3 has more recorded benchmarks, including PassMark tests that may not scale as dramatically with core count. Both processors sit at the 69th percentile of all CPUs in the database.

The nearest rivals further contextualize the two parts. The Ryzen 3 7440U's closest competitor is the Intel Core i5-11400H, which is 0.4% behind, followed by the AMD EPYC 9254 at 0.5% behind, the AMD EPYC 9354P at 0.9% behind, and the AMD EPYC 75F3 at 1.1% behind. The EPYC 7702P's closest rival is the Intel Core i3-1315U, which is 0.7% ahead, followed by the AMD EPYC 74F3 at 1.4% ahead, the Intel Core 5 211TE at 1.6% behind, and the Intel Core i7-9750H at 1.6% ahead. The Ryzen 3 competes with mobile and server parts in its average score range, while the EPYC's average score places it near low-power mobile chips, an artifact of the benchmark set used to compute the average.
