AMD Ryzen 5 3400G vs Intel Xeon E3-1280 v5 Comparison

Where Each One Wins

The benchmark data for these two processors is unusually one-sided. Across every recorded Cinebench test, the AMD Ryzen 5 3400G takes the win, leaving the Intel Xeon E3-1280 v5 with zero victories in the head-to-head comparison. The database records six head-to-head benchmark entries, and the AMD part wins all six.

The Ryzen 5 3400G dominates in both multi-threaded and single-threaded workloads. In multi-core tests, the advantage ranges from 11.6% to 11.7% depending on the Cinebench version. The single-core gap is similar, sitting between 11.7% and 12.1%. This consistency across both workload types suggests the AMD chip holds a genuine architectural edge, not just a niche advantage in one specific test.

The Xeon E3-1280 v5, despite being a server-class part, cannot match the Ryzen in any measured scenario. Its best showing comes in Cinebench R15 multicore, where it scores 707 against the Ryzen's 789, a deficit of 11.6%. In every other test, the gap widens slightly to around 11.7% or 11.8%.

Looking at the broader database averages, the Ryzen 5 3400G holds an average benchmark score of 2059 across all its recorded tests, while the Xeon E3-1280 v5 averages 2029. That puts the AMD part in the 46th percentile of all CPUs tracked, versus the 45th percentile for the Intel chip. The practical difference is small in the overall ranking, but the head-to-head results tell a clearer story.

The Verdict

The data points to one conclusion: the AMD Ryzen 5 3400G is the stronger processor in every measured benchmark. For users prioritizing raw compute performance, whether in single-threaded or multi-threaded applications, the choice is clear.

The Ryzen 5 3400G wins all six head-to-head Cinebench comparisons. Its multi-core lead of approximately 11.7% across R15, R20, and R23 means workloads like video rendering, code compilation, or batch photo processing will finish noticeably faster. The single-core advantage of roughly 11.7% to 12.1% benefits everyday responsiveness and lightly threaded applications.

The Intel Xeon E3-1280 v5 does have a few things going for it in the broader feature set. It supports ECC memory, which the Ryzen does not. It also targets the server and workstation market segment, whereas the Ryzen is a desktop part. However, in pure benchmark performance, the Xeon does not win a single recorded test.

For a workstation buyer who absolutely requires ECC memory and a locked multiplier, the Xeon E3-1280 v5 remains a defensible choice. For anyone else, especially desktop users who want the fastest measured compute performance, the Ryzen 5 3400G is the pick. The benchmark results are unambiguous.

Head-to-Head Benchmarks

The six recorded head-to-head tests all come from the Cinebench suite, covering three versions across single-core and multi-core workloads. The Ryzen 5 3400G wins every one, with deltas that stay tightly clustered.

Starting with Cinebench R15 multicore, the Ryzen scores 789 against the Xeon's 707, a lead of 11.6%. The single-core R15 test shows a slightly larger gap: 111 versus 99, which translates to 12.1%. That is the largest percentage advantage the AMD part achieves in any comparison.

Moving to Cinebench R20, the multicore result is 3290 for the Ryzen versus 2946 for the Xeon, a delta of 11.7%. The single-core R20 test has the Ryzen at 464 and the Xeon at 415, again an 11.8% advantage for AMD.

Cinebench R23 closes the set. The multicore scores are 7835 for the Ryzen and 7015 for the Xeon, an 11.7% difference. The single-core R23 test shows 1106 against 990, which is also 11.7%.

The consistency is striking. Across six tests spanning different Cinebench versions, the AMD lead never drops below 11.6% and never rises above 12.1%. This indicates a stable performance advantage that does not depend on the specific workload or benchmark generation.

For context, the Xeon E3-1280 v5 has a higher boost clock of 4.00 GHz, but the Ryzen 5 3400G boosts to 4.20 GHz. Both have the same base clock of 3.70 GHz and the same 4-core, 8-thread configuration. The Ryzen also benefits from a larger L1 cache at 96 KB per core versus 64 KB, and a larger L2 at 512 KB per core versus 256 KB. The Xeon does have double the L3 cache at 8 MB shared, but that does not translate into a benchmark win.

Architecture Differences

The two processors come from different architectural generations and target different market segments. The AMD Ryzen 5 3400G uses the Zen+ architecture with the Picasso codename, built on a 12 nm process by GlobalFoundries. The Intel Xeon E3-1280 v5 uses the Skylake architecture with the Skylake-DT codename, built on a 14 nm process by Intel.

Both chips have 4 cores and 8 threads, and both have a base clock of 3.70 GHz. The Ryzen boosts to 4.20 GHz, while the Xeon boosts to 4.00 GHz. The Ryzen has a 65 W TDP, whereas the Xeon is rated at 80 W. The Ryzen's multiplier is unlocked for overclocking, while the Xeon is locked.

The cache layout differs notably. The Ryzen 5 3400G has 96 KB of L1 cache per core and 512 KB of L2 cache per core, with 4 MB of shared L3. The Xeon E3-1280 v5 has 64 KB of L1 per core and 256 KB of L2 per core, but doubles the shared L3 to 8 MB. The Ryzen's larger L1 and L2 caches likely contribute to its single-core advantage.

The transistor counts and die sizes reflect the different process nodes. The Ryzen packs 4,940 million transistors into a 210 mm² die, while the Xeon has 1,750 million transistors on a 122 mm² die. The 12 nm process allows the AMD part to integrate more transistors despite the older Zen+ microarchitecture.

Memory support is dual-channel DDR4 for both, but the Ryzen has a recorded memory bandwidth of 46.9 GB/s, while the Xeon's memory bandwidth is not listed. The Xeon supports ECC memory, which is typical for its server and workstation market segment. The Ryzen does not support ECC and targets the desktop segment.

PCIe connectivity is Gen 3 for both, but the Xeon specifies 16 lanes from the CPU only. The Ryzen's PCIe lane count is not detailed in the database. The Xeon is end-of-life in production status, while the Ryzen is still active.

The Ryzen 5 3400G includes the Radeon RX Vega 11 integrated graphics, which adds a GPU to the package. The Xeon E3-1280 v5 has no integrated graphics, so a discrete GPU is mandatory for any display output.

In terms of platform, the Ryzen uses AMD Socket AM4, while the Xeon uses Intel Socket 1151. The Ryzen's release date is July 2019, with a launch MSRP of $149. The Xeon launched in October 2015 with a launch MSRP of $612. The Xeon's part number is SR2LC, while the Ryzen has two part numbers listed: YD3400C5M4MFH and YD3400C5FHBOX.
