AMD Ryzen 5 3400G vs Intel Xeon E3-1240 v5 Comparison

The AMD Ryzen 5 3400G and the Intel Xeon E3-1240 v5 are both quad-core, eight-thread processors, but they target very different segments of the market. The Ryzen 5 3400G is a desktop APU with integrated graphics, while the Xeon E3-1240 v5 is a server and workstation chip without any integrated graphics. The recorded data shows a clean sweep in the head-to-head benchmarks, with the AMD part winning all six compared tests. The average benchmark score for the Ryzen 5 3400G is 2059, placing it in the 46th percentile of all CPUs, while the Xeon E3-1240 v5 has an average score of 2030, placing it in the 45th percentile. This is a narrow overall margin, but the per-test results reveal a consistent pattern of AMD advantage across both single-threaded and multi-threaded workloads.

Where Each One Wins

The benchmark results are unambiguous in this comparison: the AMD Ryzen 5 3400G wins every single recorded head-to-head test. In the Cinebench R15 multicore test, the Ryzen scores 789 against the Xeon's 707, a 11.6% advantage. The single-core R15 test shows a 12.1% lead for AMD, with scores of 111 versus 99. This pattern repeats across all versions of Cinebench. In Cinebench R20, the Ryzen leads by 11.6% in multicore (3290 vs 2948) and by 11.5% in single-core (464 vs 416). The newer Cinebench R23 test shows the same 11.6% delta in multicore (7835 vs 7020) and an 11.6% delta in single-core (1106 vs 991). The Ryzen 5 3400G is clearly the stronger performer in every rendering workload included in the database.

The Xeon E3-1240 v5 has no wins to claim in this dataset. Its six losses in the head-to-head benchmarks are the only recorded results for this comparison. The Xeon does have other data points in its favor, such as support for ECC memory and a server/workstation market segment, but in raw compute benchmarks it trails the AMD part across the board. The Ryzen's wins are not concentrated in one type of workload; they span both single-thread and multi-thread tests, indicating a general performance advantage rather than a specialized one. The 3DMark results for the Ryzen 5 3400G, which are not present for the Xeon, show scores of 2414 for 16 threads, 994 for 2 threads, 1703 for 4 threads, 2391 for 8 threads, 2384 for max threads, and 516 for single-thread. These additional measurements reinforce the AMD processor's broader test coverage.

Architecture Differences

The architecture gap between these two processors is substantial. The AMD Ryzen 5 3400G uses the Zen+ architecture, codenamed Picasso, built on a 12 nm process by GlobalFoundries. It has 4 cores arranged in a design with 8 threads total. The base clock is 3.70 GHz with a boost clock of 4.20 GHz. The cache hierarchy includes 96 KB of L1 per core, 512 KB of L1 per core, and 4 MB of shared L3 cache. The processor die size is 210 mm² with 4,940 million transistors, and the TDP is rated at 65 watts. The socket is AMD Socket AM4, and the chip supports DDR4 memory on a dual-channel bus with a bandwidth of 46.9 GB/s. It does not support ECC memory. The integrated graphics are Radeon RX Vega 11, and the PCIe lanes support PCIe Gen 3. The multiplier is unlocked, making it a capable overclocking platform. The release date is listed as 2019-07-06, and the launch MSRP is $149.

The Intel Xeon E3-1240 v5 uses the Skylake architecture, codenamed Skylake-DT, built on a 14 nm process by Intel. It also has 4 cores and 8 threads, with a base clock of 3.50 GHz and a boost clock of 3.90 GHz. The cache configuration includes 64 KB of L1 per core, 256 KB of L2 per core, and 8 MB of shared L3 cache. The die size is 122 mm² with 1,750 million transistors, and the TDP is rated at 80 watts. The socket is Intel Socket 1151, and the memory support includes both DDR3 and DDR4 on a dual-channel bus with a bandwidth of 34.1 GB/s. It supports ECC memory, which is a key feature for server deployments. There is no integrated graphics. The PCIe support is Gen 3 with 16 lanes from the CPU only. The multiplier is locked, so overclocking is not an option. The production status is end-of-life, and the release date is 2015-10-18. The launch MSRP is $282.

The process node difference is notable: 12 nm for AMD versus 14 nm for Intel. The AMD chip has a larger die and more transistors, while the Intel chip has a smaller die and fewer transistors. The Xeon has more L3 cache (8 MB vs 4 MB), but the AMD chip has more L1 and L2 cache per core. Memory bandwidth favors the AMD part at 46.9 GB/s versus 34.1 GB/s. The Ryzen also has a higher base clock and a higher boost clock. The Xeon's ECC memory support is a distinguishing feature for workstation reliability. The integrated Radeon RX Vega 11 GPU on the AMD chip is a major differentiator, as the Xeon has no integrated graphics at all. The AMD part has an unlocked multiplier, while the Xeon is locked. The market segments are clearly split between desktop for AMD and server/workstation for Intel.

The Verdict

The data points to the AMD Ryzen 5 3400G as the better performer in this matchup. The six wins in the head-to-head benchmarks are the core of the comparison, and they all favor AMD. The Ryzen has higher clocks, more total cache bandwidth in some areas, and a newer architecture. The Xeon E3-1240 v5 retains relevance only in scenarios where ECC memory support is required, as the recorded data shows that feature is present on the Intel chip but missing on the AMD chip. The Ryzen also has a lower TDP of 65 watts, a longer production status of active, and a release date in 2019. The Xeon is end-of-life with a release in 2015. The Ryzen average score of 2059 versus 2030 is a 1.4% difference in favor of AMD, which is small relative to the per-test deltas.

The Xeon E3-1240 v5 is positioned for server workloads where ECC memory support and reliability matter more than raw speed. The AMD Ryzen 5 3400G is for a desktop user who wants integrated graphics and 3DMark results, which are only recorded for the AMD part. The Xeon does not record 3DMark scores in this database, so those are exclusively AMD territory. The verdict is clear from the numbers alone. The AMD Ryzen 5 3400G wins all six tests, and the Xeon E3-1240 v5 has zero wins. The AMD Ryzen 5 3400G has a higher 3dmark single thread score of 516. The Xeon has no comparable data to challenge that metric. The division of who should pick what is simple from the data available. The Ryzen 5 3400G for performance and the Xeon E3-1240 v5 for ECC support, with the understanding that the Xeon loses every benchmark test in the database.
