AMD EPYC 7702P vs AMD Ryzen 3 4100 Comparison

The Verdict

The AMD EPYC 7702P is a server/workstation processor built around 64 Zen 2 cores with 128 threads, while the AMD Ryzen 3 4100 is a desktop chip with 4 Zen 2 cores and 8 threads. The benchmark data is unambiguous: the EPYC 7702P wins all six recorded head-to-head Cinebench tests, with deltas ranging from 456.8% to 459.4% in its favor. The Ryzen 3 4100 records zero wins in the head-to-head set. The EPYC 7702P belongs in a server or workstation where massive parallel throughput is the priority. The Ryzen 3 4100, with its 65 W TDP and unlocked multiplier, serves a desktop use case where the EPYC 7702P's 200 W TDP and Socket SP3 platform are inappropriate. Neither chip is a substitute for the other; the data supports a clear divide between rack-mount compute and small-form-factor desktop builds.

Architecture Differences

Both processors use the Zen 2 microarchitecture and are fabricated by TSMC on a 7 nm process. The similarities end there. The EPYC 7702P, codenamed Rome, packs 64 cores and 128 threads at a base clock of 2000.00 MHz and a boost clock of 3.35 GHz. Its cache hierarchy includes 96 KB of L1 per core, 512 KB of L2 per core, and a massive 256 MB of shared L3. Memory support is DDR4 over an eight-channel bus, yielding 204.8 GB/s of memory bandwidth. It supports ECC memory, uses PCIe Gen 4, and fits the AMD Socket SP3 platform. The package contains 3,800 million transistors on a 74 mm² die.

The Ryzen 3 4100, codenamed Renoir, is a 4-core, 8-thread part with a base clock of 3.80 GHz and a boost clock of 4.00 GHz. L1 is 64 KB per core, L2 is 512 KB per core, and L3 is 8 MB shared. It runs DDR4 on a dual-channel bus for 51.2 GB/s of memory bandwidth, does not support ECC, and uses PCIe Gen 3 with 8 CPU lanes. The socket is AMD Socket AM4. The transistor count is 9,800 million on a 156 mm² die, which is substantially more transistors and a larger die than the EPYC 7702P despite having far fewer cores. The Ryzen 3 4100 has an unlocked multiplier for overclocking, while the EPYC 7702P does not. The EPYC 7702P targets the server/workstation segment and remains in active production; the Ryzen 3 4100 targets the desktop segment and also remains active.

Head-to-Head Benchmarks

The recorded head-to-head set consists entirely of Cinebench tests, and the EPYC 7702P dominates each one. In Cinebench R15 multicore, the EPYC 7702P scores 5272 against the Ryzen 3 4100's 946, a delta of 457.3%. The single-core R15 test shows the EPYC 7702P at 744 versus 133, a 459.4% advantage. The R20 multicore test puts the EPYC 7702P at 21969 and the Ryzen 3 4100 at 3945, a 456.9% gap. R20 single-core records 3101 versus 556, a 457.7% delta. In R23 multicore, the EPYC 7702P reaches 52308 while the Ryzen 3 4100 manages 9394, a 456.8% difference. R23 single-core shows 7384 versus 1326, a 456.9% gap.

The pattern is consistent: the EPYC 7702P leads by roughly 4.5 to 4.6 times in every Cinebench test, whether single-core or multi-core. The single-core deltas are actually slightly higher than the multi-core ones in R15 and R20, which suggests the EPYC 7702P's higher per-core cache and memory bandwidth help it even in lightly threaded workloads. The Ryzen 3 4100's higher base and boost clocks (3.80 GHz and 4.00 GHz versus 2000.00 MHz and 3.35 GHz) do not translate into a single-core victory. The EPYC 7702P's 256 MB of shared L3 and eight-channel memory path appear to overcome the clock disadvantage.

The average benchmark scores from the broader database support the same ordering, though with a narrower margin. The EPYC 7702P has an average benchmark score of 15130, while the Ryzen 3 4100 sits at 14505. The EPYC 7702P ranks at the 69th percentile among all CPUs, and the Ryzen 3 4100 also ranks at the 69th percentile. The nearest rivals for the EPYC 7702P include the Intel Core i3-1315U at 15022 (0.7% behind), the AMD EPYC 74F3 at 14915 (1.4% behind), the Intel Core 5 211TE at 15370 (1.6% ahead), and the Intel Core i7-9750H at 14886 (1.6% behind). For the Ryzen 3 4100, the nearest rivals are the AMD Ryzen 3 4300G at 14503 (0% delta), the Intel Xeon 6315P at 14574 (0.5% ahead), the AMD EPYC 7473X at 14574 (0.5% ahead), and the AMD Ryzen 5 5500U at 14589 (0.6% ahead). These rival sets show that both processors sit in similar overall performance percentiles when averaged across all benchmark types, despite the massive Cinebench gap, because the EPYC 7702P's database includes workloads where the Ryzen 3 4100's PassMark results contribute heavily to its average.

The Ryzen 3 4100 has additional PassMark and Geekbench results not present for the EPYC 7702P. In Geekbench multicore it scores 5310, and in single-core 1423. PassMark multithread shows 11050, single-thread 2531, integer math 32307, floating-point math 19128, data compression 149609, data encryption 9133, extended instructions 9923, find prime numbers 23, physics 563, and random string sorting 15760. These figures are not part of the head-to-head set, so they cannot be compared directly, but they indicate that the Ryzen 3 4100 is a capable general-purpose desktop chip in its own right.

Where Each One Wins

The EPYC 7702P wins every recorded head-to-head benchmark, so the straightforward answer is that it wins in all six Cinebench categories. The practical interpretation is that the EPYC 7702P is the correct choice for workloads that scale with core count, thread count, and memory bandwidth. Its 64 cores and 128 threads, combined with 256 MB of L3 and 204.8 GB/s of eight-channel memory bandwidth, make it suitable for server virtualization, large-scale compilation, scientific computing, and other server/workstation tasks where the 200 W TDP is an acceptable trade-off. The lack of an unlocked multiplier is irrelevant in that context, as server workloads rarely rely on manual overclocking.

The Ryzen 3 4100, despite losing all six head-to-head tests, has strengths that the head-to-head set does not capture. Its 65 W TDP, Socket AM4 compatibility, and unlocked multiplier make it a desktop-oriented part. The PassMark results show strong integer math (32307), floating-point math (19128), and multithread (11050) scores for a 4-core chip. Data compression (149609) and random string sorting (15760) suggest it handles everyday desktop tasks well. The dual-channel memory bus and 51.2 GB/s bandwidth are sufficient for typical consumer workloads, and PCIe Gen 3 with 8 CPU lanes matches mainstream desktop platforms. The Ryzen 3 4100 also carries a launch MSRP of $99, which the database records but this analysis does not expand upon.

The percentile data places both processors at the 69th percentile among all CPUs, indicating that their overall average performance across the database is similar. That is a reminder that the EPYC 7702P's Cinebench dominance is specific to those render workloads, while the Ryzen 3 4100's broader benchmark suite pulls its average up. Users who need maximum multi-threaded render performance should choose the EPYC 7702P. Users who need a low-power desktop processor with overclocking headroom should choose the Ryzen 3 4100. The EPYC 7702P's nearest rivals include the Intel Core i3-1315U, AMD EPYC 74F3, Intel Core 5 211TE, and Intel Core i7-9750H, all within 1.6% of its average score. The Ryzen 3 4100's nearest rivals include the AMD Ryzen 3 4300G, Intel Xeon 6315P, AMD EPYC 7473X, and AMD Ryzen 5 5500U, all within 0.6% of its average. These rival clusters confirm that each processor competes in a different performance tier despite the shared architecture and percentile ranking.
