AMD Ryzen 7 1700 vs Intel Xeon E3-1270 v5 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive multi-core victory for the AMD Ryzen 7 1700. In the Cinebench R15 multi-core test, the Ryzen 7 1700 scores 1414, while the Intel Xeon E3-1270 v5 manages only 713. That is a 49.6% deficit for the Xeon, meaning the AMD processor delivers roughly twice the threaded throughput. For workloads that scale across cores, this is not a close contest; the Ryzen part simply has double the physical cores and threads, and the benchmark reflects that advantage directly.

Single-core performance tells a different story, but still favors AMD in the recorded results. In Cinebench R15 single-core, the Ryzen 7 1700 posts 147, while the Xeon E3-1270 v5 scores 100. That is a 32% gap in favor of the AMD chip. This is notable because Intel's Skylake architecture traditionally holds a clock-speed advantage, with the Xeon boosting to 4.00 GHz versus the Ryzen's 3.70 GHz boost. Despite the higher boost clock, the Xeon still trails in this particular single-threaded test. The Ryzen 7 1700's newer Zen core design appears to overcome the clock deficit in this workload.

Across the broader benchmark suite in the database, the average scores are nearly identical. The Xeon E3-1270 v5 averages 2048, and the Ryzen 7 1700 averages 2015. That is a difference of only 33 points, roughly 1.6%. This near-parity in the aggregate average masks the very different performance profiles: the Xeon leans on efficiency and higher clocks in lighter tasks, while the Ryzen excels in heavily threaded scenarios. The database records two head-to-head wins for the AMD part and zero for the Intel part, so the direct comparison in the shared Cinebench R15 tests is unambiguous.

The percentile rankings also reflect this split. The Xeon E3-1270 v5 sits at the 46th percentile among all CPUs in the database, while the Ryzen 7 1700 sits at the 45th percentile. For practical purposes, these are equivalent positions in the overall distribution. A buyer choosing between them based purely on aggregate standing would see no meaningful separation, but the workload-specific scores reveal where each processor belongs.

Architecture Differences

The architectural gap between these two processors is substantial, even though both are built on a 14 nm process. The Intel Xeon E3-1270 v5 uses the Skylake architecture, specifically the Skylake-DT codename, and is manufactured by Intel. The AMD Ryzen 7 1700 uses the Zen architecture, codenamed Zen (Summit Ridge), and is fabricated by GlobalFoundries. Both chips use 14 nm lithography, but the transistor counts diverge sharply: the Xeon packs 1,750 million transistors on a 122 mm² die, while the Ryzen 7 1700 contains 4,800 million transistors on a 213 mm² die. The AMD part is physically larger and far more complex, which aligns with its 8-core, 16-thread configuration.

Core and thread counts are the most obvious differentiator. The Xeon E3-1270 v5 offers 4 cores and 8 threads, a classic hyper-threaded quad-core layout. The Ryzen 7 1700 doubles that to 8 cores and 16 threads. This explains the multi-core benchmark gap almost entirely. Cache hierarchies also differ. The Xeon provides 64 KB of L1 per core, 256 KB of L2 per core, and 8 MB of shared L3 cache. The Ryzen 7 1700 provides 96 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. The AMD processor has more cache at every level, which contributes to its stronger showing in the single-core test despite a lower boost clock.

Memory support is another point of divergence. The Xeon E3-1270 v5 supports both DDR3 and DDR4 memory, while the Ryzen 7 1700 supports DDR4 only. Both run dual-channel memory buses, but the peak bandwidth figures differ: the Xeon reaches 34.1 GB/s, while the Ryzen 7 1700 reaches 42.7 GB/s. The AMD part enjoys a roughly 25% higher theoretical memory bandwidth, which matters for memory-sensitive workloads. Both processors support ECC memory, so that is not a distinguishing factor. Both also use PCIe Gen 3 with 16 CPU lanes, so expansion capability is identical.

The sockets are entirely incompatible. The Xeon uses Intel Socket 1151, while the Ryzen 7 1700 uses AMD Socket AM4. This is a fundamental platform decision: choosing one locks out the other's motherboard ecosystem. The market segments also differ. The Xeon is classified as a Server/Workstation part, while the Ryzen 7 1700 is a Desktop processor. The Xeon is end-of-life in the database, whereas the Ryzen 7 1700 is marked as Active. The Ryzen 7 1700 also has an unlocked multiplier, while the Xeon is locked, giving the AMD part overclocking headroom that the Intel part lacks.

Where Each One Wins

The Ryzen 7 1700 wins where thread count matters. In multi-core rendering, video encoding, compilation, and any parallel workload, the 8-core, 16-thread configuration gives it a massive edge. The Cinebench R15 multi-core score of 1414 versus 713 is a 49.6% lead, and that kind of margin translates directly into shorter render times and faster batch processing. For a workstation user running heavily threaded applications, the Ryzen 7 1700 is the clear choice based on the recorded data.

The single-core result also favors the Ryzen 7 1700 in the database, with a 147 to 100 win in Cinebench R15 single-core, a 32% advantage. This is somewhat surprising given the Xeon's higher boost clock of 4.00 GHz versus 3.70 GHz. The Zen architecture's efficiency per clock appears to compensate, and the larger cache and higher memory bandwidth likely contribute. For everyday responsiveness, lighter single-threaded applications, and typical desktop use, the data suggests the Ryzen 7 1700 holds the advantage here as well.

The Xeon E3-1270 v5 does not win any recorded head-to-head benchmark. Its strengths lie in platform characteristics rather than raw scores. It supports both DDR3 and DDR4 memory, which offers flexibility for system builders with existing DDR3 modules. Its 80 W TDP is higher than the Ryzen's 65 W, but it draws that power across fewer cores. The Xeon's smaller die and lower transistor count suggest lower manufacturing complexity, and its status as a Server/Workstation part points to a different intended environment. Still, based purely on benchmark outcomes in the database, the AMD processor wins every shared test.

For users already invested in the Intel Socket 1151 platform, the Xeon E3-1270 v5 remains a functional option for light server duties or ECC-capable builds. But the data does not show a single benchmark category where the Xeon outperforms the Ryzen 7 1700. The aggregate average scores are close, but the workload-specific results consistently favor AMD.

Specification Differences

The two processors differ in nearly every fundamental specification except process node and PCIe configuration. The Xeon E3-1270 v5 has 4 cores and 8 threads, while the Ryzen 7 1700 has 8 cores and 16 threads. Base clocks are 3.60 GHz for the Xeon and 3.00 GHz for the Ryzen. Boost clocks are 4.00 GHz and 3.70 GHz, respectively. The Intel part has a higher clock at both ends, but the AMD part wins on core count and cache.

Thermal design power differs as well: the Xeon is rated at 80 W, the Ryzen 7 1700 at 65 W. Despite having twice the cores, the AMD processor carries a lower TDP, which is a notable efficiency result in the database. The Xeon's memory support spans DDR3 and DDR4, while the Ryzen is DDR4-only. Memory bandwidth favors the Ryzen at 42.7 GB/s versus 34.1 GB/s. L1 cache 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 8 MB shared versus 16 MB shared. Every cache level is larger on the AMD part.

The Ryzen 7 1700 has an unlocked multiplier; the Xeon does not. The Ryzen is classified as Active production status, while the Xeon is End-of-life. The Ryzen belongs to the 1000 series with the part number YD1700BBAEBOX, while the Xeon carries the part number SR2LF. The Ryzen's launch MSRP is $329, and the Xeon's launch MSRP is $339. Both support ECC memory, both use PCIe Gen 3 with 16 CPU lanes, and neither has integrated graphics.

The Verdict

The data points to the AMD Ryzen 7 1700 as the stronger processor in every recorded benchmark. It wins both head-to-head tests, with a 49.6% margin in multi-core and a 32% margin in single-core. It offers double the cores and threads, larger caches, higher memory bandwidth, a lower TDP, and an unlocked multiplier. It is also marked as Active in the database, while the Xeon is End-of-life. For a new build, especially one aimed at threaded workloads, the Ryzen 7 1700 is the clear pick from the recorded measurements.

The Intel Xeon E3-1270 v5 still has a place for specific scenarios. Its support for both DDR3 and DDR4 memory provides flexibility for reusing older RAM. Its Server/Workstation market segment and ECC support make it viable for light server roles. Its higher boost clock of 4.00 GHz, while not translating into a single-core win in the data, could appeal to users who prefer Intel's platform. However, no benchmark in the database shows the Xeon ahead, and its aggregate average score of 2048 is nearly identical to the Ryzen's 2015, so there is no recorded performance justification to choose it over the AMD part.

The verdict is straightforward: the Ryzen 7 1700 is the better processor by every measured metric in this comparison. The Xeon E3-1270 v5 is an older, less capable part that survives on platform compatibility and ECC support. For anyone building a system today, the AMD Ryzen 7 1700 delivers more cores, more cache, better benchmark results, and a lower TDP. The only reason to consider the Xeon is a pre-existing Intel Socket 1151 motherboard or a specific need for DDR3 memory support, both of which are platform considerations rather than performance advantages.
