AMD Ryzen Embedded 9900X3D vs Intel Core 3 305 Comparison

Head-to-Head Benchmarks

The recorded data shows a stark contrast between these two processors, though direct head-to-head benchmark results are unavailable in the database. The AMD Ryzen Embedded 9900X3D has no benchmark entries on file, while the Intel Core 3 305 carries a full suite of Cinebench and PassMark scores. Consequently, all quantitative comparisons must be framed through the Intel chip's absolute performance and its standing against its nearest rivals, rather than a direct score-for-score duel.

The Intel Core 3 305 delivers a Cinebench R23 multi-core score of 13123 points and a single-core score of 1852 points. In Cinebench R20, it records 5511 points multi-core and 777 points single-core. The older R15 test shows 1322 points multi-core and 186 points single-core. These figures indicate a processor that scales reasonably well in threaded workloads relative to its modest core count.

PassMark results reinforce this picture. The chip scores 3977 in single-thread performance, 15439 in multithreaded performance, and 42284 in floating-point math. Integer math lands at 32295, while extended instructions reach 13543. Data compression hits 146857, data encryption scores 11019, and random string sorting produces 17623. Physics calculations yield 1233, and prime number finding scores a low 115, which suggests limited performance in that specific integer-heavy algorithm.

Against its nearest rivals in the database, the Intel Core 3 305 sits just 0.1% behind the Intel Core i3-14100, which has an average score of 18318. It trails the Intel Core 5 330 and Intel Core 7 360 by 0.2% and 0.4%, respectively, with those chips scoring 18345 and 18374. Conversely, it leads the AMD Ryzen 5 2600E by 0.4%, as that processor averages 18230. The Core 3 305's own average benchmark score is 18302, placing it at the 72nd percentile among all CPUs in the database.

The AMD Ryzen Embedded 9900X3D, by contrast, holds a 50th percentile ranking with an average benchmark score of 0, meaning no recorded measurements exist for it. This absence of data prevents any numerical head-to-head analysis. What the database does reveal is the architectural disparity between the two, which strongly implies divergent performance profiles despite the lack of direct scores.

Architecture Differences

The two processors come from different manufacturing nodes and design philosophies. The AMD Ryzen Embedded 9900X3D uses a 4 nm process from TSMC, while the Intel Core 3 305 uses a 3 nm process from Intel's own foundry. The AMD part is built on the Granite Ridge codename within the Ryzen Embedded generation, based on Zen 5 cores. The Intel chip uses the Wildcat Lake codename within the Core 3 generation.

Core and thread counts differ substantially. The AMD processor offers 12 cores and 24 threads, while the Intel chip provides 6 cores and 6 threads, meaning the Intel part has no hyperthreading support. Clock speeds also diverge: the AMD chip has a base clock of 4.40 GHz and a boost clock of 5.50 GHz, whereas the Intel chip runs at 1.50 GHz base and 4.30 GHz boost. The AMD processor's TDP is 120 watts, compared to 15 watts for the Intel part.

Cache hierarchies are organized differently. The AMD chip features 80 KB of L1 cache per core, 1 MB of L2 per core, and 128 MB of L3 cache. The Intel chip has 192 KB of L1 cache total, 2.5 MB of L2, and 6 MB of shared L3. The AMD processor's massive L3 allocation is the standout feature, likely contributing to its expected performance in cache-sensitive workloads.

Memory support varies significantly. The AMD chip supports DDR5 over a dual-channel bus with 89.6 GB/s of bandwidth and includes ECC memory support. The Intel chip supports both DDR5 and LPDDR5X but runs over a single-channel bus with 59.7 GB/s of bandwidth and no ECC support. PCIe connectivity also differs: the AMD part offers Gen 5 with 24 lanes (CPU only), while the Intel part provides Gen 4 with 6 lanes (CPU only).

Integrated graphics diverge as well. The AMD processor includes Radeon Graphics, while the Intel chip uses Intel Xe3 Graphics with 1 Xe core. The AMD chip has an unlocked multiplier, whereas the Intel chip does not. Transistor counts and die sizes are recorded for the AMD part (16,630 million transistors, 2x 70.6 mm² die size) but are absent for the Intel part.

The Verdict

The database presents an unusual situation. The AMD Ryzen Embedded 9900X3D has no benchmark scores on file, leaving its performance entirely unquantified relative to the Intel Core 3 305. The Intel chip, meanwhile, is thoroughly measured and ranks at the 72nd percentile among all CPUs, with an average score of 18302 that places it within 0.4% of its nearest competitors.

For users prioritizing measured, verified performance, the Intel Core 3 305 is the only option with data to support a decision. Its single-thread score of 3977 in PassMark and 1852 in Cinebench R23 indicate solid per-core performance for a 6-core, 6-thread part. Its multithreaded Cinebench R23 score of 13123 shows that the six physical cores handle threaded workloads adequately, though the lack of hyperthreading limits scaling.

The AMD Ryzen Embedded 9900X3D offers a fundamentally different hardware profile. With 12 cores, 24 threads, a 5.50 GHz boost clock, 128 MB of L3 cache, and DDR5 dual-channel memory, its specifications suggest substantially higher multi-threaded and cache-sensitive performance than the Intel chip. However, the database contains no recorded scores to confirm this. Users choosing the AMD part must rely on its architectural advantages rather than empirical results.

From a market segment perspective, the AMD chip targets the desktop space with a 120-watt TDP, while the Intel chip targets mobile with a 15-watt TDP. The Intel part's launch MSRP is $309, a figure that appears nowhere in the comparison since the AMD chip has no listed launch MSRP. The AMD chip's production status is Active, as is the Intel chip's, and both have release dates in the database: October 6, 2025 for the AMD part and April 15, 2026 for the Intel part.
