AMD Ryzen Embedded R2544 vs Intel Xeon E3-1275 v5 Comparison

The AMD Ryzen Embedded R2544 and the Intel Xeon E3-1275 v5 are both 4-core, 8-thread processors, but they come from different eras and design philosophies. The R2544 is a 12 nm Zen+ part from the 2000 series, released in September 2022, while the Xeon E3-1275 v5 is a 14 nm Skylake part released in October 2015. Benchmark results from the database show the AMD part winning all six head-to-head Cinebench tests, though by narrow margins. The R2544 records an average benchmark score of 2086, placing it in the 46th percentile of all CPUs, while the Xeon E3-1275 v5 scores 2043, landing in the 45th percentile.

Head-to-Head Benchmarks

The head-to-head data covers three Cinebench versions, each with single-core and multi-core tests. In Cinebench R15 multi-core, the R2544 scores 726 against the Xeon's 712, a 2% lead. In R15 single-core, the R2544 scores 102 against 100, also a 2% lead. Moving to Cinebench R20, the multi-core test shows the R2544 at 3029 versus 2967, a 2.1% advantage. The R20 single-core test yields the largest delta of the set: the R2544 scores 427, the Xeon scores 418, a 2.2% lead. In Cinebench R23, the multi-core result is 7213 for the R2544 and 7065 for the Xeon, a 2.1% gap, while the single-core test shows 1018 against 997, again a 2.1% gap. Across all six tests, the AMD part wins every time, but the margins are consistent and modest, ranging from 2% to 2.2%. The average benchmark scores reinforce this: the R2544's 2086 sits 43 points above the Xeon's 2043. The percentile rankings also reflect the narrow overall gap, with the R2544 at the 46th percentile and the Xeon at the 45th.

Where Each One Wins

Given that the R2544 wins all six head-to-head tests, it holds the advantage in both single-threaded and multi-threaded workloads across all three Cinebench versions. For single-core performance, the R2544 leads by 2% in R15, 2.2% in R20, and 2.1% in R23. For multi-core, it leads by 2% in R15, 2.1% in R20, and 2.1% in R23. The Xeon E3-1275 v5 does not win any of the recorded tests, so its use case is limited to scenarios where its specific platform features, such as its 8 MB shared L3 cache or its support for both DDR3 and DDR4 memory, are more relevant than raw Cinebench scores. Looking at the broader competitive landscape, the R2544's average score of 2086 places it 0.2% above the Intel Core i3-9350KF (2082) and 0.3% above the Intel Xeon W-2123 (2079). It trails the AMD Ryzen 7 1700X (2094) by 0.4% and the Intel Core i3-8350K (2096) by 0.5%. The Xeon E3-1275 v5, with its average of 2043, sits 0.2% above the Intel Core i7-7700T (2039) and 0.3% above the AMD Opteron 6386 SE (2038). It falls 0.1% short of the AMD Ryzen 5 7520U (2046) and 0.2% short of the Intel Xeon E3-1270 v5 (2048). This places the R2544 in a slightly higher performance tier than the Xeon, though both are closely matched with their respective rivals.

Architecture Differences

The two processors are built on fundamentally different architectures. The R2544 uses AMD's Zen+ architecture, codenamed Picasso, fabricated on a 12 nm process at GlobalFoundries. The Xeon E3-1275 v5 uses Intel's Skylake architecture, codenamed Skylake-DT, on a 14 nm process at Intel. The R2544 integrates 4,940 million transistors on a 210 mm² die, while the Xeon packs 1,750 million transistors on a 122 mm² die. The cache hierarchies also differ. The R2544 has 96 KB of L1 cache per core and 512 KB of L2 cache per core, with a 4 MB shared L3 cache. The Xeon has 64 KB of L1 per core and 256 KB of L2 per core, but a larger 8 MB shared L3 cache. Memory support diverges as well: the R2544 supports DDR4 only, with a dual-channel bus and a memory bandwidth of 51.2 GB/s. The Xeon supports both DDR3 and DDR4, also dual-channel, but with a lower memory bandwidth of 34.1 GB/s. Both support ECC memory. The integrated graphics differ: the R2544 features a Radeon Vega 8, while the Xeon has an HD Graphics P530. The R2544 uses the AMD Socket FP5, while the Xeon uses Intel Socket 1151. The R2544 has a TDP of 45 W, significantly lower than the Xeon's 80 W.
