AMD Ryzen 5 3400GE vs Intel Xeon E5-4648 v3 Comparison

The Intel Xeon E5-4648 v3 and AMD Ryzen 5 3400GE represent two fundamentally different approaches to computing, separated by four years of silicon evolution and targeting entirely different market segments. The comparison data reveals a striking paradox: a 12-core, 24-thread server processor from 2015 and a 4-core, 8-thread desktop APU from 2019 land within 2.5% of each other on every Cinebench test, despite their architectural chasm. The Xeon has massive core-count advantages and a much larger shared cache, yet the Ryzen’s higher clock speeds and newer process node nearly erase that gap entirely, raising the question of what raw core counts actually mean in real-world multi-threaded workloads.

Architecture Differences

The architectural divide between these two processors is vast. The Intel Xeon E5-4648 v3 is built on the Haswell-EP microarchitecture using Intel’s 22 nm process, with 2,600 million transistors packed into a 356 mm² die. It features 12 cores and 24 threads, with a base clock of 1700 MHz and a boost clock of 2.20 GHz. The cache hierarchy is generous: 64 KB of L1 per core, 256 KB of L2 per core, and a substantial 30 MB of shared L3 cache. This is a server/workstation part designed for Intel Socket 2011-3, supporting quad-channel DDR4 memory with 59.7 GB/s of bandwidth and ECC memory. It also offers PCIe Gen 3 with 40 lanes from the CPU.

In contrast, the AMD Ryzen 5 3400GE is a Zen+ (Picasso) part built on GlobalFoundries’ 12 nm process, with 4,940 million transistors on a 210 mm² die. It has 4 cores and 8 threads, with a much higher base clock of 3.30 GHz boosting to 4.00 GHz. Its cache configuration is smaller: 96 KB of L1 per core, 512 KB of L2 per core, and only 4 MB of shared L3 cache. The Ryzen uses AMD Socket AM4, supports dual-channel DDR4 with 46.9 GB/s bandwidth, and does not support ECC memory. It includes integrated Radeon RX Vega 11 graphics, a feature entirely absent from the Xeon. The Ryzen is also multiplier-unlocked, while the Xeon is locked. The transistor density difference is stark: the Ryzen fits 4,940 million transistors into 210 mm² versus 2,600 million into 356 mm², reflecting the newer 12 nm node.

The Verdict

The benchmark data presents an unusual verdict: despite the Xeon’s overwhelming core-count advantage, the two processors are virtually tied in performance. The Xeon wins all six head-to-head Cinebench tests, but the largest margin is a mere 2.8% in R15 single-core. The average benchmark score tells the same story — the Xeon scores 2227 versus the Ryzen’s 2175, a difference of about 2.4%. Both processors sit at the 47th percentile of all CPUs, placing them squarely in the mid-range of overall performance.

Who should pick which? The data suggests the Xeon is for workloads that genuinely scale with cores and memory bandwidth — its 30 MB L3 cache, quad-channel memory, and ECC support make it suited for server-style tasks, though its end-of-life status and 105 W TDP are drawbacks. The Ryzen 5 3400GE, with its 35 W TDP, integrated Vega 11 graphics, unlocked multiplier, and active production status, is the practical choice for a desktop system where power efficiency and graphics capability matter. However, the benchmark results indicate that raw core count is not the deciding factor here — clock speed and IPC nearly compensate for the 3x core deficit. Users needing pure multi-threaded throughput would still favor the Xeon, but only by a hair, while anyone building a new system today would find the Ryzen’s feature set more compelling.

Specification Differences

The two processors differ across nearly every specification field. The Xeon has 12 cores and 24 threads versus the Ryzen’s 4 cores and 8 threads. Base clocks differ significantly: 1700 MHz for the Xeon versus 3300 MHz for the Ryzen, with boost clocks of 2.20 GHz and 4.00 GHz respectively. TDP is a major differentiator — the Xeon draws 105 W, while the Ryzen draws just 35 W. Sockets are incompatible: Intel Socket 2011-3 versus AMD Socket AM4.

The architecture generation separates them by four years: Haswell-EP versus Zen+ (Picasso). Process nodes differ (22 nm vs 12 nm), as do foundries (Intel vs GlobalFoundries). Transistor counts and die sizes are reversed in density — the Xeon has 2,600 million transistors on 356 mm², while the Ryzen has 4,940 million on 210 mm². Cache configurations differ: L1 is 64 KB per core on the Xeon versus 96 KB per core on the Ryzen; L2 is 256 KB per core versus 512 KB per core; L3 is 30 MB shared versus 4 MB shared. Memory support differs: both use DDR4, but the Xeon has quad-channel with 59.7 GB/s bandwidth, while the Ryzen has dual-channel with 46.9 GB/s. ECC support is present on the Xeon but absent on the Ryzen. The Xeon offers PCIe Gen 3 with 40 lanes, while the Ryzen lists only PCIe Gen 3 without a lane count. Integrated graphics exist only on the Ryzen (Radeon RX Vega 11). Market segments differ (Server/Workstation vs Desktop), production status differs (End-of-life vs Active), release dates differ (2015 vs 2019), and the Ryzen has an unlocked multiplier while the Xeon does not.

Head-to-Head Benchmarks

The six head-to-head Cinebench tests show a remarkably consistent pattern. In Cinebench R15 multicore, the Xeon scores 776 against the Ryzen’s 757, a 2.5% win. The R15 single-core test shows the Xeon at 109 versus 106, a 2.8% margin — the largest gap in any test. Moving to R20, the Xeon leads 3234 to 3158 in multicore (2.4%) and 456 to 445 in single-core (2.5%). The R23 tests follow suit: multicore 7701 vs 7520 (2.4%) and single-core 1087 vs 1061 (2.5%).

The pattern is telling. The Xeon’s biggest win is in single-core R15, not multicore, which runs counter to expectations given its 3x core advantage. The multicore margins (2.4–2.5%) are essentially identical to the single-core margins (2.5–2.8%), suggesting the Xeon’s advantage comes from per-core efficiency rather than core count scaling. The Ryzen’s 3.30 GHz base clock and 4.00 GHz boost clock appear to nearly offset the Xeon’s core advantage, though the Xeon’s larger 30 MB L3 cache and quad-channel memory bandwidth may contribute to its consistent, if narrow, lead across all workloads.

Where Each One Wins

The Intel Xeon E5-4648 v3 wins in every benchmark category, but the victories are marginal. Its 2.5% lead in multicore tests like Cinebench R15 (776 vs 757) and R23 (7701 vs 7520) suggests it holds an edge in multi-threaded rendering and compute workloads, likely aided by its 30 MB L3 cache and quad-channel memory subsystem. The Xeon’s 2.8% single-core R15 win (109 vs 106) indicates it also retains a slight per-thread advantage despite its much lower clock speeds. The Xeon’s strengths are its 12-core/24-thread configuration, ECC memory support, and 59.7 GB/s memory bandwidth — features geared toward server and workstation environments where data integrity and memory throughput are critical.

The AMD Ryzen 5 3400GE has zero benchmark wins, but its strengths lie outside raw Cinebench scores. Its 35 W TDP is one-third of the Xeon’s 105 W, making it dramatically more power-efficient. It includes Radeon RX Vega 11 integrated graphics, eliminating the need for a discrete GPU. Its unlocked multiplier allows overclocking, and its active production status means it remains available for new builds. The Ryzen’s 12 nm process and 4,940 million transistors on a smaller die indicate a more modern design that achieves near-parity with a much larger, more power-hungry server chip. For desktop users prioritizing power efficiency, integrated graphics, and upgradeability, the Ryzen is the clear choice — even though the data shows it loses every performance test, the losses are so small (under 3%) that they may be imperceptible in real-world use.
