AMD Ryzen 7 2700E vs Intel Xeon E5-1681 v3 Comparison

The Intel Xeon E5-1681 v3 and the AMD Ryzen 7 2700E are two very different processors that land at nearly identical performance levels in the database. The Xeon is a 10-core, 20-thread Haswell-EP part from 2014, while the Ryzen is an 8-core, 16-thread Zen+ desktop chip from 2018. Despite the generational gap, their average benchmark scores are remarkably close: the Xeon averages 3643, and the Ryzen averages 3603. Both sit at the 55th percentile among all CPUs, meaning they are squarely in the mid-range of the current database. The data shows a consistent, albeit narrow, advantage for the Intel part across every single Cinebench test, with the Ryzen never managing a single win.

Head-to-Head Benchmarks

The most striking pattern in the head-to-head data is the uniformity of the margins. In every Cinebench test—R15, R20, and R23, both single-core and multi-core—the Intel Xeon E5-1681 v3 wins by exactly 1.1%. That is a very consistent delta, suggesting the two chips are effectively trading blows at the margin, with Intel holding a slight edge in both single-threaded and heavily threaded workloads.

In Cinebench R15 multi-core, the Xeon scores 1269 against the Ryzen's 1255. That is a 14-point gap, which is tiny in absolute terms. The single-core R15 result is even closer: 179 for the Intel versus 177 for the AMD, a 2-point difference. Moving to Cinebench R20, the Xeon posts 5290 multi-core and 746 single-core, while the Ryzen manages 5232 and 738, respectively. The deltas remain at that same 1.1% figure.

The Cinebench R23 results tell the same story. The Xeon scores 12597 in multi-core, and the Ryzen scores 12458. In single-core, the Xeon hits 1778, and the Ryzen hits 1758. In all six tests, the Intel part wins, but the margins are so thin that in real-world usage, the difference would be imperceptible. The data indicates that the Xeon's two extra cores and four extra threads give it just enough multi-core muscle to edge out the Ryzen, while its older Haswell architecture still manages to keep pace in single-core performance against the newer Zen+ design.

Looked at from a different angle, the Ryzen's 4.00 GHz boost clock versus the Xeon's 3.50 GHz boost clock does not translate into a single-core advantage for AMD. The benchmark results show that raw clock speed alone is not the deciding factor, as the Intel part wins every single-core test despite a 500 MHz disadvantage on paper. The average scores also confirm the closeness: the Xeon's 3643 is just 1.1% above the Ryzen's 3603.

The Verdict

From the data, the choice between these two comes down to platform priorities rather than raw performance. The Intel Xeon E5-1681 v3 wins every benchmark in this comparison, but by a margin of only 1.1% in each case. If the decision is made purely on Cinebench scores, the Xeon is the marginally faster processor. It offers 10 cores and 20 threads versus the Ryzen's 8 cores and 16 threads, and the extra compute resources show up as consistent wins across all six tests.

However, the Ryzen 7 2700E has its own compelling arguments. It is a desktop part with a 65 W TDP, versus the Xeon's 135 W TDP. That is a massive difference in power draw, and it means the Ryzen will be far easier to cool and will generate significantly less heat. The Ryzen also uses the AMD Socket AM4 platform, which offers a more modern and consumer-friendly upgrade path compared to the Intel Socket 2011-3 server platform. The Xeon is end-of-life, while the Ryzen is still active in production.

The data does not show a performance winner that matters in practice. A 1.1% delta is within run-to-run variance for most workloads. The real verdict is that the Xeon is the right choice if you need the extra two cores and are building on a workstation platform, while the Ryzen is the better pick if power efficiency, platform modernity, and a consumer socket matter more than a marginal benchmark lead. Neither processor is a clear winner; the Xeon wins on pure scores, but the Ryzen wins on efficiency and platform fit.

Architecture Differences

The architectural divide between these two chips is significant. The Intel Xeon E5-1681 v3 is built on Intel's 22 nm process, using the Haswell-EP architecture with the codename Haswell-EP. It is a server and workstation part, and its transistor count is 2,600 million on a 356 mm² die. The Ryzen 7 2700E, by contrast, uses AMD's Zen architecture (specifically Zen+ Pinnacle Ridge) on a 12 nm process from GlobalFoundries. It packs 4,800 million transistors into a much smaller 192 mm² die. This means the Ryzen has roughly 84% more transistors in a 46% smaller area, which reflects the density improvements of the newer node.

Core and cache configurations also differ. The Xeon has 10 cores and 20 threads, with 64 KB of L1 cache per core, 256 KB of L2 per core, and a 25 MB shared L3 cache. The Ryzen has 8 cores and 16 threads, with 96 KB of L1 per core, 512 KB of L2 per core, and a 16 MB shared L3 cache. The Xeon has more total L3 cache and more threads, while the Ryzen has larger per-core L1 and L2 caches. Memory support is another differentiator: both support DDR4, but the Xeon runs a quad-channel memory bus with a rated bandwidth of 68.3 GB/s, while the Ryzen uses a dual-channel bus with no bandwidth figure listed. The Xeon also supports ECC memory, while the Ryzen does not.

The platforms are completely different. The Xeon uses Intel Socket 2011-3 and offers PCIe Gen 3 with 40 lanes from the CPU. The Ryzen uses AMD Socket AM4 and has no PCIe lane count listed in the data. The Xeon is marked as end-of-life, released in September 2014, while the Ryzen was released in September 2018 and is still active. The Ryzen's memory bus is dual-channel, which is typical for consumer desktop parts, while the Xeon's quad-channel setup is aimed at memory-intensive server workloads. Neither chip has integrated graphics, and neither has an unlocked multiplier.

Where Each One Wins

The Intel Xeon E5-1681 v3 wins every single benchmark in this head-to-head comparison. It takes the multi-core tests in Cinebench R15 with a score of 1269, in R20 with 5290, and in R23 with 12597. It also wins the single-core tests, scoring 179 in R15, 746 in R20, and 1778 in R23. The Xeon's advantage is consistent at 1.1% across all tests. This makes it the clear pick if you need the absolute highest Cinebench score available from these two options. Its 10 cores and 20 threads, combined with a 25 MB shared L3 cache and quad-channel memory, give it an edge in heavily threaded workloads.

The AMD Ryzen 7 2700E does not win a single benchmark test, but it wins in other areas that are not captured by Cinebench. Its 65 W TDP is less than half the Xeon's 135 W, making it the far more power-efficient choice. The Ryzen is also an active production part on the AM4 socket, whereas the Xeon is end-of-life on the Intel Socket 2011-3 platform. If you are building a new system today, the Ryzen offers a modern platform with a smaller die (192 mm² versus 356 mm²) and a 12 nm process node versus the Xeon's 22 nm. The Ryzen's larger per-core L1 cache (96 KB versus 64 KB) and L2 cache (512 KB versus 256 KB) may help in certain workloads that benefit from faster per-core data access. The Ryzen is the better choice for a low-power desktop build, while the Xeon is the better choice for a used workstation or server board where the extra cores and memory bandwidth are more valuable.
