The Verdict

The data indicates two completely different market positions. The AMD Ryzen 3 8300G is a fully benchmarked, active desktop part with a recorded average score of 18169 and a 72nd percentile standing. The AMD Ryzen Embedded 9900X, despite being active and aimed at the desktop segment, has zero benchmark records in the database, giving it an average score of 0 and a 50th percentile. From the recorded data alone, the 8300G is the only one with verifiable performance; the 9900X cannot be evaluated on measured results.

For users needing a small-core-count part with proven single-thread and multi-thread scores, the 8300G is the data-backed choice. Its nearest rivals in the database include the AMD Ryzen 7 5700U with an average score of 18176 and a delta of 0%, the Intel Core i7-1365U at 18177 with a delta of 0%, the Intel Core i7-9700 at 18180 with a delta of -0.1%, and the Intel Core i5-1334U at 18154 with a delta of 0.1%. This places the 8300G in a tight pack where it trades fractions of a percent with those parts.

The Ryzen Embedded 9900X, with 12 cores, 24 threads, a 4.40 GHz base, and a 5.60 GHz boost, has the structural advantage on paper. It also carries a 120 W TDP versus the 65 W TDP of the 8300G. However, without any benchmark entries, the database cannot confirm how those specifications translate into measured performance. The 9900X is the pick for users who prioritize core count, cache capacity, and PCIe Gen 5 connectivity, but only as a specification-based selection, not a benchmark-verified one.

Head-to-Head Benchmarks

The head-to-head benchmark table between these two processors is empty. There are no recorded wins for either part in direct comparison. The wins counter shows 0 for both the AMD Ryzen 3 8300G and the AMD Ryzen Embedded 9900X. This means the database holds no side-by-side test results that pit these two specific models against each other in any workload.

What the database does contain is a full benchmark suite for the 8300G. In Cinebench R15, it scores 1231 in multicore and 173 in singlecore. In Cinebench R20, the multicore score reaches 5131 and singlecore reaches 724. In Cinebench R23, the multicore score is 12217 and the singlecore score is 1724. PassMark results for the 8300G include 158952 in data compression, 9115 in data encryption, 12354 in extended instructions, 47 in find prime numbers, 25336 in floating point math, 40534 in integer math, 14018 in multithread, 755 in physics, 19013 in random string sorting, and 3778 in single thread.

The Ryzen Embedded 9900X has an empty benchmarks array. There are no Cinebench scores, no PassMark scores, and no average benchmark score. Its percentile of 50 is the default baseline, while the 8300G sits at the 72nd percentile. The absence of measurements means any head-to-head comparison must rely on the 8300G's recorded results against its nearest rivals, not against the 9900X directly.

Relative to its nearest rivals, the 8300G shows a nearly identical average score. It is 0.1% behind the Intel Core i7-9700, which records an average score of 18180. It is 0.1% ahead of the Intel Core i5-1334U, which records 18154. It matches the AMD Ryzen 7 5700U at 18176 and the Intel Core i7-1365U at 18177 with a delta of 0%. The 8300G is effectively within a rounding error of all four rivals in average benchmark score.

Specification Differences

The two processors diverge sharply in core count. The Ryzen 3 8300G has 4 cores and 8 threads. The Ryzen Embedded 9900X has 12 cores and 24 threads, a threefold increase in both. Clock speeds also differ: the 8300G runs at 3.40 GHz base and 4.90 GHz boost, while the 9900X runs at 4.40 GHz base and 5.60 GHz boost. The 9900X holds the advantage in both base and boost clocks.

Thermal design power differs as well. The 8300G is rated at 65 W TDP. The 9900X is rated at 120 W TDP. Both use AMD Socket AM5. Memory support is DDR5 for both, and both run dual-channel memory buses. Memory bandwidth is higher on the 9900X at 89.6 GB/s versus 83.2 GB/s on the 8300G.

PCIe capability splits by generation and lane count. The 8300G has PCIe Gen 4 with 14 lanes. The 9900X has PCIe Gen 5 with 24 lanes. The 9900X also has an unlocked multiplier, while the 8300G does not. The 8300G has a launch MSRP of $176. The 9900X has no launch MSRP recorded in the database.

The integrated graphics differ by name: the 8300G uses Radeon 740M, while the 9900X uses Radeon Graphics. Both are active production parts. Release dates differ, with the 8300G released on 2024-01-07 and the 9900X released on 2025-10-06. Part numbers are 100-000001492 for the 8300G and 100-000000662E for the 9900X.

Architecture Differences

The Ryzen 3 8300G is built on Zen 4 architecture with the codename Phoenix2. The database lists its generation as Ryzen 3 (Zen 4 (Phoenix)). The Ryzen Embedded 9900X uses the codename Granite Ridge with an architecture field left blank, and its generation is listed as Ryzen Embedded (Zen 5 (Granite Ridge)). This indicates a generational gap, with Zen 4 on the 8300G and Zen 5 on the 9900X.

Both processors are fabricated on a 4 nm process at TSMC. The 8300G has a transistor count of 20,900 million and a die size of 137 mm². The 9900X has 16,630 million transistors and a die size listed as 2x 70.6 mm², indicating a dual-die design. The 8300G uses a single 137 mm² die.

Cache architecture differs significantly. The 8300G has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 8 MB of shared L3 cache. The 9900X has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of L3 cache. The L3 cache difference is substantial: 64 MB on the 9900X versus 8 MB on the 8300G, an eightfold gap in shared cache.

The integrated graphics are also different. The 8300G features Radeon 740M, while the 9900X features Radeon Graphics. Both support ECC memory. The 9900X has an unlocked multiplier, which the 8300G lacks, indicating overclocking headroom on the larger part.

Where Each One Wins

The Ryzen 3 8300G wins in the database because it has measured results. It records an average benchmark score of 18169 and a 72nd percentile ranking. Its nearest rivals cluster tightly around it: the AMD Ryzen 7 5700U at 18176, the Intel Core i7-1365U at 18177, the Intel Core i7-9700 at 18180, and the Intel Core i5-1334U at 18154. The 8300G is within 0.1% of all four, showing it competes evenly with those established desktop and mobile parts in average score.

The 8300G also demonstrates strong single-core and multi-core numbers in Cinebench. Its Cinebench R23 multicore score of 12217 and singlecore score of 1724 show balanced performance. In PassMark, its integer math score of 40534 and floating point math score of 25336 indicate solid compute throughput. Data compression at 158952 and random string sorting at 19013 round out a complete workload profile.

The Ryzen Embedded 9900X wins on paper specifications. It has 12 cores and 24 threads, three times the core count of the 8300G. Its 64 MB L3 cache is eight times larger than the 8 MB on the 8300G. Its 5.60 GHz boost clock is 0.70 GHz higher than the 4.90 GHz boost on the 8300G. Its PCIe Gen 5 with 24 lanes doubles the lane count and upgrades the generation over the Gen 4 with 14 lanes on the 8300G. Its memory bandwidth of 89.6 GB/s is 6.4 GB/s higher.

For workloads that rely on core count, cache capacity, and PCIe bandwidth, the 9900X is the specification winner. For workloads that rely on verified benchmark scores, the 8300G is the only part with data. The 8300G is the choice for users who want a 65 W part with a proven average score and a launch MSRP of $176. The 9900X is the choice for users who need 24 threads, 64 MB of L3 cache, PCIe Gen 5, and an unlocked multiplier, accepting that its performance has no recorded measurements in the database.
