AMD Ryzen Embedded V3C18I vs Intel Core i7-5960X Comparison

Head-to-Head Benchmarks

The benchmark data is unambiguous: the AMD Ryzen Embedded V3C18I wins every single recorded head-to-head comparison against the Intel Core i7-5960X. Across six Cinebench tests, the AMD part takes all six victories, with margins ranging from 1.8% to 1.9%. This is a consistent, narrow but complete sweep. The Intel i7-5960X does not secure a single win in any recorded benchmark.

In Cinebench R15 multicore, the Ryzen Embedded scores 1187 against Intel's 1165, a 1.9% advantage. The single-core R15 test shows a similar pattern: 167 versus 164, a 1.8% lead for AMD. Moving to Cinebench R20, the multicore result is 4946 for AMD versus 4857 for Intel, again a 1.8% gap. The R20 single-core test shows 698 versus 685, a 1.9% margin.

The newer Cinebench R23 workloads reinforce the trend. In multicore, AMD scores 11777, Intel manages 11565, a 1.8% difference. In single-core R23, AMD posts 1662, Intel 1632, another 1.8% gap. Every benchmark in the database follows this pattern: AMD leads, Intel trails, and the margins are remarkably consistent between 1.8% and 1.9%.

The average benchmark score tells a slightly different story. The Intel i7-5960X has an average score of 3442, while the AMD Ryzen Embedded V3C18I averages 3406. This puts Intel slightly ahead in the overall average, despite losing every head-to-head test. The explanation lies in the Geekbench results, which are recorded for Intel but absent for AMD in the head-to-head comparison. Intel's Geekbench multicore score of 6461 and single-core score of 1010 pull its average upward.

Both processors sit at the 54th percentile of all CPUs in the database. They are effectively tied in overall standing, with the AMD part recording a 54th percentile and Intel also at 54. The nearest rivals for each confirm their close positioning. Intel's closest competitor is the AMD Ryzen 3 PRO 5350G with an average score of 3441, a 0% delta, followed by the AMD Ryzen 5 4600HS at 3444, also 0% delta. The AMD Ryzen Embedded's nearest rival is the Intel Xeon E-2236 at 3410, a 0.1% deficit, and the Intel Xeon E-2146G at 3410, also 0.1% behind.

Where Each One Wins

The AMD Ryzen Embedded V3C18I wins in every Cinebench generation, both single-core and multicore. This is a complete victory in the rendering and compute workloads that Cinebench represents. The margins, while small, are consistent across all versions of the test from R15 through R23. This suggests a fundamental efficiency advantage that persists regardless of workload intensity or thread count.

The Intel Core i7-5960X wins in the Geekbench tests, where it has recorded scores of 6461 multicore and 1010 single-core. These results are not part of the head-to-head comparison table, but they are present in the database. The Geekbench suite tests a broader range of real-world scenarios, including memory access patterns and cryptographic workloads, which may favor Intel's architecture.

For users focused on sustained multi-threaded rendering, the AMD part is the clear choice. Its multicore Cinebench scores are higher in every test, even though both CPUs have 8 cores and 16 threads. For users who rely on Geekbench-style workloads, Intel holds the edge, though the database does not provide a direct head-to-head Geekbench comparison between these two specific processors.

The wins split along generational lines. AMD wins the Cinebench family outright, Intel wins the Geekbench family by default because AMD has no recorded Geekbench scores in the database. This is not a case where Intel beats AMD on Geekbench; rather, the data is incomplete for AMD on that test.

Architecture Differences

The two processors come from different eras and design philosophies. The Intel Core i7-5960X uses the Haswell architecture, specifically Haswell-E, built on Intel's 22 nm process node. It features 8 cores and 16 threads, with a base clock of 3.00 GHz and a boost clock of 3.50 GHz. The die size is 356 mm², and it contains 2,600 million transistors. The thermal design power is 140 watts.

The AMD Ryzen Embedded V3C18I uses the Zen 3+ architecture, codenamed Rembrandt, built on TSMC's 6 nm process node. It also has 8 cores and 16 threads, but its base clock is 1900.00 MHz (1.90 GHz) and its boost clock is 3.80 GHz. The TDP is dramatically lower at 15 watts. The database does not record a transistor count or die size for the AMD part.

Cache configurations differ. Both have 64 KB of L1 cache per core. The L2 cache is 256 KB per core on Intel, while AMD provides 512 KB per core. The L3 cache is 20 MB shared on Intel, 16 MB shared on AMD. This gives Intel a larger total L3, but AMD doubles the per-core L2.

Memory support is a major differentiator. Intel uses DDR4 with a quad-channel memory bus, providing 68.3 GB/s of bandwidth. AMD uses DDR5 with a dual-channel bus, providing 76.8 GB/s. Despite having half the channels, AMD's DDR5 support delivers higher bandwidth. AMD also supports ECC memory, while Intel does not.

PCIe connectivity favors Intel in lane count but AMD in generation. Intel provides Gen 3 with 40 lanes (CPU only). AMD provides Gen 4 with 20 lanes (CPU only). The newer Gen 4 standard offers higher per-lane bandwidth, but Intel offers twice the lane count.

The socket and platform are entirely different. Intel uses Socket 2011-3, AMD uses Socket FP7. The Intel part has an unlocked multiplier, AMD does not. Intel's production status is end-of-life, AMD is active. The release dates are separated by eight years: Intel launched on 2014-08-31, AMD on 2022-09-26.

FAQ

Q: Which processor has more cores?

A: Both have the same number: 8 cores and 16 threads each. The core count is identical, so any performance difference comes from architecture, clock speeds, and memory support.

Q: Does the AMD part really beat Intel in every Cinebench test?

A: Yes. The database shows AMD winning all six head-to-head Cinebench tests, from R15 to R23, in both single-core and multicore. The margins are between 1.8% and 1.9% in every case.

Q: Why is Intel's average benchmark score higher if it loses all head-to-head tests?

A: Intel has recorded Geekbench scores (6461 multicore, 1010 singlecore) that are included in its average. The AMD part has no Geekbench scores in the database, so its average of 3406 is based only on Cinebench results. Intel's average is 3442.

Q: How do the power requirements compare?

A: The Intel Core i7-5960X has a TDP of 140 watts. The AMD Ryzen Embedded V3C18I has a TDP of 15 watts. This is a substantial difference, with AMD consuming far less power per the recorded specifications.

Q: Which processor supports faster memory?

A: AMD supports DDR5 memory with a dual-channel bus and 76.8 GB/s bandwidth. Intel supports DDR4 with a quad-channel bus and 68.3 GB/s bandwidth. AMD's memory bandwidth is higher despite fewer channels.

Q: Is the Intel processor still in production?

A: No. The database lists Intel's production status as end-of-life. The AMD part is listed as active production.

The Verdict

The data points to a clear conclusion for most users: the AMD Ryzen Embedded V3C18I is the better processor in the Cinebench workloads that are the only direct head-to-head comparisons available. It wins every test, and it does so while consuming dramatically less power. The 140-watt TDP of Intel versus the 15-watt TDP of AMD is a massive efficiency gap that cannot be ignored. For any application where power consumption, heat output, or cooling requirements matter, AMD is the obvious choice.

The Intel Core i7-5960X retains an advantage in Geekbench scores, but this is not a direct comparison. The database does not record Geekbench results for AMD, so Intel's Geekbench wins are by default, not by measurement. Users who specifically rely on Geekbench as their primary benchmark should note that Intel's scores are higher, but they should also note the lack of AMD data.

The Intel part offers more PCIe lanes (40 versus 20) and a larger L3 cache (20 MB versus 16 MB). The AMD part offers newer PCIe Gen 4, higher memory bandwidth, ECC support, and a modern 6 nm process. The eight-year gap in release dates explains most of these differences.

For new systems, the AMD Ryzen Embedded V3C18I is the rational pick. It wins on performance in the measured tests, wins overwhelmingly on efficiency, supports ECC memory, and is actively produced. The Intel Core i7-5960X is end-of-life, uses older DDR4, and consumes nearly ten times the power. The only scenarios where Intel makes sense are those requiring 40 PCIe lanes or those specifically tuned for Geekbench workloads with no need for power efficiency.

The verdict is straightforward: AMD wins on recorded benchmark performance, power efficiency, memory technology, and production status. Intel wins on PCIe lane count, L3 cache size, and Geekbench scores that lack a direct AMD comparison.
