AMD Ryzen Embedded V1202B vs Intel Core i7-4558U Comparison

Head-to-Head Benchmarks

The recorded data shows a clean sweep for the AMD Ryzen Embedded V1202B across all five shared benchmark tests. In every Cinebench iteration, the AMD part finishes ahead by a consistent margin of roughly 15%. The Intel Core i7-4558U trails in each instance, and the gap is remarkably uniform, suggesting a steady performance advantage rather than a workload-specific edge.

Starting with Cinebench R15 multicore, the AMD Ryzen Embedded V1202B scores 300 against the Intel Core i7-4558U's 255. That is a 15% deficit for the Intel chip. Moving to Cinebench R20 multicore, the AMD part posts 1253 while the Intel part manages 1063, a 15.2% gap. The single-core results tell the same story: in Cinebench R20 single-core, AMD scores 176 versus Intel's 149, again a 15.3% difference. Cinebench R23 multicore shows AMD at 2985 and Intel at 2532, a 15.2% shortfall for Intel, while the R23 single-core test has AMD at 421 and Intel at 357, also 15.2% behind.

The pattern is clear: the Ryzen Embedded V1202B outperforms the i7-4558U by a nearly identical percentage in every measured test. There is no test where the Intel chip pulls ahead, and no test where the AMD advantage shrinks meaningfully. This consistency points to a fundamental throughput advantage for the AMD design rather than an optimization quirk in any single benchmark.

Where Each One Wins

Based strictly on the benchmark data, the AMD Ryzen Embedded V1202B wins every category where a comparison exists. That includes both multi-core and single-core rendering workloads. The Cinebench R23 single-core result of 421 for AMD versus 357 for Intel means the AMD chip is also stronger in lightly threaded tasks, not just heavily parallel ones. The same holds for Cinebench R20 single-core, where AMD's 176 beats Intel's 149.

For users prioritizing rendering performance, the AMD part is the clear choice. The Intel Core i7-4558U does not claim a single win in any of the five head-to-head tests. Its best showing is in Cinebench R15 multicore, where the 255 score is still 15% behind AMD's 300. Even in average benchmark score across all recorded tests, the Intel part sits at 1038 against AMD's 1027, but that figure includes additional Geekbench results for Intel that are not part of the shared head-to-head set.

The Intel chip does have its own unique benchmark data: Geekbench multicore at 1967 and single-core at 941. These scores are not directly comparable to the AMD part, since the Ryzen Embedded V1202B has no Geekbench entry in the database. So while the Intel chip has more recorded data points, the shared tests all favor AMD.

The Verdict

The data is unambiguous. The AMD Ryzen Embedded V1202B outperforms the Intel Core i7-4558U in every single benchmark where both were tested. The margin is a steady 15% or slightly higher, and it applies to both multi-core and single-core workloads. If the choice comes down to raw compute performance, the AMD part wins outright.

The Intel Core i7-4558U does have a higher clock speed on paper, with a base of 2.80 GHz and a boost of 3.30 GHz, compared to AMD's 2.30 GHz base and 3.20 GHz boost. Yet the benchmark results show the AMD chip still comes out ahead. That means the architectural efficiency of the Zen design more than compensates for the lower clock rates.

Users should also consider the thermal envelope. The AMD Ryzen Embedded V1202B has a TDP of 15 watts, while the Intel Core i7-4558U is rated at 28 watts. The AMD part delivers better performance while drawing less power, which is a notable advantage for compact or fanless systems. The Intel chip does have a higher average benchmark score in the full database (1038 versus 1027), but that figure includes Geekbench results that are not part of the head-to-head comparison, and the percentile ranking is identical at 28 for both.

For anyone choosing between these two, the AMD Ryzen Embedded V1202B is the stronger performer in every measured metric. The Intel part offers no countervailing performance win in the recorded data.

Architecture Differences

The two processors come from different architectural generations and design philosophies. The Intel Core i7-4558U is built on the Haswell architecture, specifically the Haswell-ULT variant, using a 22 nm process node from Intel's own foundry. The AMD Ryzen Embedded V1202B uses the Zen architecture on a 14 nm process from GlobalFoundries.

The transistor counts differ substantially. The Intel chip contains 1,300 million transistors on a die size of 118 mm². The AMD chip packs 4,950 million transistors into a larger die of 210 mm². That is a major difference in transistor density and total logic. The AMD design has more than three times the transistor count of the Intel part, which explains its higher efficiency despite a lower clock speed.

Cache hierarchies also diverge. The Intel Core i7-4558U has 64 KB of L1 cache per core, 256 KB of L2 per core, and 4 MB of shared L3 cache. The AMD Ryzen Embedded V1202B doubles the L1 and L2 allocations, with 128 KB of L1 per core and 512 KB of L2 per core, but its shared L3 cache is smaller at 2 MB. The AMD part compensates with larger per-core caches, while the Intel part offers a bigger pool of shared L3.

Memory support differs as well. The Intel chip uses DDR3, while the AMD chip uses DDR4 with a dual-channel memory bus. The AMD part also integrates a Radeon Vega 3 graphics solution, whereas the Intel part uses Intel HD 5100 graphics. Neither supports ECC memory.

The platform sockets are not interchangeable. The Intel Core i7-4558U uses Intel BGA 1168, while the AMD Ryzen Embedded V1202B uses AMD Socket FP5. The Intel part is marked as a mobile segment product, while the AMD part is listed as a desktop segment product. The AMD chip has an active production status, while the Intel chip's production status is not listed.
