AMD Ryzen Embedded V2748 vs Intel Core i7-7820X Comparison

Head-to-Head Benchmarks

The head-to-head data is remarkably consistent across the entire Cinebench suite. The AMD Ryzen Embedded V2748 wins all six recorded comparisons, with every delta falling between 7.2% and 7.6%. This is not a case of one workload favoring a particular architecture; the margin is nearly identical regardless of thread count or render complexity.

Starting with Cinebench R15, the V2748 scores 1579 in multi-core against 1469 for the i7-7820X, a 7.5% advantage. The single-core result shows 222 versus 207, a 7.2% edge. Moving to Cinebench R20, the pattern holds: the AMD part posts 6580 multi-core and 929 single-core, while Intel manages 6121 and 863 respectively, producing deltas of 7.5% and 7.6%. Cinebench R23 repeats the same story with a 15668 to 14576 multi-core victory (7.5%) and a 2212 to 2057 single-core win (7.5%).

The consistency of these margins suggests a fundamental clock-for-clock efficiency advantage rather than a workload-specific quirk. The Intel part has a higher boost clock at 4.50 GHz versus 4.25 GHz, yet still loses every race. The Ryzen's higher instructions-per-clock from the Zen 2 architecture compensates for the lower frequency ceiling.

The average benchmark score in the database reinforces this picture. The V2748 carries an avgBenchmarkScore of 4532, while the i7-7820X sits at 4321. Both processors land in the 58th percentile versus all CPUs, so they occupy a similar tier in the overall performance distribution, but the AMD chip consistently sits slightly higher within that band.

When placed against their respective nearest rivals, both processors perform close to their expected neighborhood. The V2748's nearest competitors include the Intel Core i5-1340P (4545 avg, -0.3% delta), Intel Core i7-10700KF (4547 avg, -0.3%), Intel Xeon E-2356G (4548 avg, -0.3%), and Intel Core i5-1250P (4515 avg, +0.4%). The i7-7820X's nearest rivals are the AMD Ryzen 7 PRO 5750G (4296 avg, +0.6%), AMD EPYC 7232P (4354 avg, -0.8%), Intel Xeon E5-4669 v3 (4285 avg, +0.8%), and Intel Xeon W-2140B (4272 avg, +1.1%). These figures show that the two CPUs are aligned with different performance clusters, with the V2748 grouping around 4500 and the i7-7820X grouping around 4300.

The Verdict

From the recorded benchmark data, the AMD Ryzen Embedded V2748 is the clear winner. It outperforms the Intel Core i7-7820X in every single test recorded in the database, with no countervailing performance category where Intel takes the lead. The margin is not trivial either: a consistent 7.5% across the board is a meaningful generational improvement.

The data shows that the V2748 achieves this victory while operating at a 35 W TDP compared to the i7-7820X's 140 W TDP. That is a substantial efficiency gap that has no bearing on the benchmark scores themselves, but it contextualizes how much more work the AMD processor does per watt. The Intel part consumes four times the thermal envelope to produce slower results in every measured test.

For builders who prioritize raw rendering performance in Cinebench workloads, the choice is unambiguous. The V2748 wins every multi-core and single-core test. The i7-7820X does retain some advantages in other specification areas, such as quad-channel memory and 28 PCIe lanes, but those do not show up in the recorded CPU benchmark scores.

The production status also matters. The V2748 is listed as Active, while the i7-7820X is End-of-life. For new system designs, the AMD part represents a currently supported option, whereas the Intel processor is a legacy product. The i7-7820X carries a launch MSRP of $599, a figure that was set at its 2017 release, but current market pricing is not part of the database's assessment.

Where Each One Wins

The AMD Ryzen Embedded V2748 wins in every benchmark category recorded. The six Cinebench tests cover both multi-threaded rendering and single-threaded responsiveness, and the AMD part takes all of them. The largest recorded margin is 7.6% in Cinebench R20 single-core, and the smallest is 7.2% in Cinebench R15 single-core. Multi-core margins sit at 7.5% across R15, R20, and R23.

The Intel Core i7-7820X has no benchmark wins in the database. However, its specification sheet reveals areas where it could be preferable in real-world system design, even though those advantages do not translate into Cinebench victories. The quad-channel memory bus with 85.3 GB/s bandwidth versus the V2748's dual-channel 51.2 GB/s could benefit memory-intensive workloads outside the recorded tests. The 28 PCIe Gen 3 lanes versus 20 lanes provide more room for expansion cards and storage devices.

The i7-7820X also has an unlocked multiplier, allowing manual overclocking, while the V2748 is locked. Overclocking could theoretically close the performance gap, but the database contains no overclocked benchmark results to verify that assumption. The Intel part's higher base clock of 3.60 GHz versus 2.90 GHz and higher boost clock of 4.50 GHz versus 4.25 GHz do not help it in the recorded stock tests.

Architecture Differences

The two processors come from very different design generations. The AMD Ryzen Embedded V2748 uses the Zen 2 architecture with the Renoir codename, built on a 7 nm process at TSMC. It integrates 9,800 million transistors on a 156 mm² die. The Intel Core i7-7820X uses the Skylake architecture with the Skylake-X codename, built on a 14 nm process at Intel's own foundry. The database does not list transistor count or die size for the Intel part.

The cache hierarchies differ significantly. Both have 64 KB of L1 cache per core, but the L2 cache differs: the V2748 has 512 KB per core, while the i7-7820X has 1 MB per core. The L3 cache also favors Intel: 11 MB shared versus 8 MB shared on the AMD part. Despite the larger cache, the Intel processor still loses every benchmark.

The V2748 includes integrated graphics with Radeon Graphics 448SP, while the i7-7820X has no integrated graphics. The AMD part supports ECC memory, the Intel part does not. The V2748 is a locked processor, while the i7-7820X has an unlocked multiplier for overclocking.

The generation labels reflect their respective lineages. The V2748 belongs to the Ryzen Embedded (Zen 2 Renoir) generation from the 2000 series. The i7-7820X belongs to the Core i7 X-Series 7th Gen. The production timelines are also distinct: the V2748 was released on 2020-11-09, while the i7-7820X was released on 2017-06-25.

Specification Differences

The most striking specification difference is TDP. The V2748 draws 35 W, while the i7-7820X draws 140 W. Both have 8 cores and 16 threads, so the core count does not explain the efficiency gap.

Clock speeds favor Intel on paper. The i7-7820X has a base clock of 3.60 GHz and a boost clock of 4.50 GHz. The V2748 has a base clock of 2.90 GHz and a boost clock of 4.25 GHz. The benchmark results show that the lower-clocked AMD part still wins.

Memory configuration differs substantially. The V2748 uses dual-channel DDR4 with 51.2 GB/s bandwidth. The i7-7820X uses quad-channel DDR4 with 85.3 GB/s bandwidth. The Intel part has a theoretical memory bandwidth advantage of 34.1 GB/s, but this does not manifest as a Cinebench win.

PCIe connectivity also favors Intel. The i7-7820X provides 28 Gen 3 lanes, while the V2748 provides 20 Gen 3 lanes. Socket compatibility is entirely separate: the AMD part uses Socket FP6, the Intel part uses Socket 2066.

The V2748 has a part number of 100-000000245, while the i7-7820X has a part number of SR3L5. The Intel part has a launch MSRP of $599, while the AMD part has no listed launch MSRP. The V2748 includes Radeon integrated graphics, the i7-7820X has none. The V2748 supports ECC memory, the i7-7820X does not. The production status also differs: Active for AMD, End-of-life for Intel.
