AMD Ryzen 5 8500G vs AMD Ryzen Embedded 9900X Comparison

Where Each One Wins

The recorded data presents an unusual comparison because the AMD Ryzen Embedded 9900X has no benchmark entries in the database, while the AMD Ryzen 5 8500G has a full suite of scores. The 8500G therefore claims every measured win by default, with winsA recorded as 0 for the 9900X and 0 for the 8500G in the head-to-head field, though the benchmark list for the 8500G shows 24 separate tests. The 8500G scores across 3DMark, Cinebench, Geekbench, and Passmark suites, covering single-threaded, multi-threaded, physics, encryption, compression, integer math, floating-point math, and prime-number workloads.

The 8500G delivers its strongest multi-threaded results in Cinebench R23 multicore at 18368 points, Geekbench multicore at 9444 points, and Passmark multithread at 21610 points. These scores position the chip at the 74th percentile among all CPUs in the database, with an average benchmark score of 20425. Its nearest rivals include the AMD EPYC 9454P with an average score of 20422, the Intel Core Ultra 7 258V at 20454, the AMD Ryzen 5 5600 at 20468, and the AMD EPYC 7713 at 20363. The deltas are tight: the 8500G sits within 0.3% of the EPYC 7713, within 0.2% of the Ryzen 5 5600, and within 0.1% of the Core Ultra 7 258V, while matching the EPYC 9454P almost exactly.

For single-threaded performance, the 8500G posts a 3DMark single-thread score of 998, Cinebench R23 single-core of 2593, Geekbench single-core of 2354, and Passmark single-thread of 3891. The Passmark physics test yields 1318, while data compression reaches 250197 and data encryption hits 14220. The 9900X has no comparable measurements, so the data cannot show where it wins.

Architecture Differences

The two processors share a 4 nm TSMC process node, AMD Socket AM5, DDR5 memory support, dual-channel memory buses, and ECC memory capability. Beyond those commonalities, the designs diverge substantially. The 8500G uses the Zen 4 architecture under the Phoenix2 codename, part of the 8000 series, with a 65 W TDP. It packs 6 cores and 12 threads, with a base clock of 3.50 GHz and a boost clock of 5.00 GHz. The transistor count is 20,900 million on a die size of 137 mm². Its cache layout includes 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The integrated graphics are Radeon 740M, and the PCIe support is Gen 4 with 14 lanes from the CPU. The multiplier is locked, and the market segment is listed as Mobile.

The 9900X belongs to the 9000 series with the Granite Ridge codename, using the Zen 5 generation as noted in the generation field. It doubles the core count to 12 cores and 24 threads, with a base clock of 4.40 GHz and a boost clock of 5.60 GHz. The TDP is 120 W, considerably higher. The transistor count is 16,630 million, lower than the 8500G despite the larger core count, spread across two dies of 70.6 mm² each. The L1 cache grows to 80 KB per core, L2 remains 1 MB per core, and L3 expands to 64 MB total. Memory bandwidth is higher at 89.6 GB/s versus 83.2 GB/s. PCIe support jumps to Gen 5 with 24 lanes from the CPU. The integrated graphics are listed simply as Radeon Graphics, the multiplier is unlocked, and the market segment is Desktop.

The cache hierarchy differs meaningfully: the 9900X has 25% more L1 per core and four times the shared L3 capacity. The 8500G has a larger total transistor budget and a single monolithic die, while the 9900X uses a chiplet design with two CCDs. The generation field explicitly labels the 9900X as Zen 5, a newer microarchitecture than the 8500G's Zen 4. The 8500G targets the mobile segment despite using a desktop socket, whereas the 9900X is positioned for embedded desktop use.

Head-to-Head Benchmarks

The head-to-head benchmark list is empty, meaning the database contains no direct comparison scores between the 8500G and the 9900X. All quantitative analysis must therefore rely on the 8500G's absolute scores and its position relative to other CPUs in the database.

The 8500G's Cinebench R23 multicore score of 18368 places it in a competitive range against its nearest rivals. The Intel Core Ultra 7 258V averages 20454, which is 0.1% higher, so the 8500G trails that chip by a narrow margin in aggregate. The AMD Ryzen 5 5600 averages 20468, 0.2% ahead, while the AMD EPYC 9454P at 20422 is essentially tied at a 0% delta. The AMD EPYC 7713 at 20363 sits 0.3% behind the 8500G. These deltas indicate that the 8500G's average performance lands squarely in a cluster of server and mobile processors with similar overall capability.

In single-threaded workloads, the 8500G shows a Geekbench single-core score of 2354 and a Cinebench R23 single-core score of 2593. The Passmark single-thread rating of 3891 and 3DMark single-thread score of 998 round out the picture. Multi-threaded scaling is evident in the 3DMark suite: the 2-thread score of 1913 rises to 3130 at 4 threads, 4565 at 8 threads, and 5213 at max threads, with the 16-thread score at 5224 nearly identical to the max-thread result. This suggests the 6-core, 12-thread configuration saturates by 8 to 12 threads, as expected for a chip with this core count.

The Passmark suite reveals specific workload strengths. Integer math scores 63123, floating-point math scores 39074, and extended instructions score 19098. Data compression reaches 250197, which is the highest single score in the entire benchmark set. Data encryption scores 14220, random string sorting scores 29407, and find prime numbers scores only 87, indicating a relative weakness in that specific prime-number algorithm. The physics score of 1318 is modest compared to the multithread score of 21610.

The 9900X has no recorded scores, no average benchmark score (listed as 0), and no nearest rivals. Its percentile rank is 50, which is the midpoint of the database distribution, but this is not backed by any measured entries. The data cannot support any claim about how the 9900X performs in Cinebench, Geekbench, Passmark, or 3DMark.

The Verdict

The data supports a clear conclusion only for the 8500G, since the 9900X has no benchmark measurements. The 8500G achieves a 74th percentile ranking among all CPUs in the database, with an average benchmark score of 20425. Its nearest rivals, all within 0.3% of its average score, include the AMD EPYC 9454P, Intel Core Ultra 7 258V, AMD Ryzen 5 5600, and AMD EPYC 7713. This places the 8500G in a dense performance cluster where the differences between chips are negligible in aggregate terms.

For users selecting between these two specific parts, the architecture data shows the 9900X offers double the cores and threads, a newer Zen 5 generation, higher clocks, more L3 cache, higher memory bandwidth, and PCIe Gen 5 support. The 8500G counters with a lower TDP, a monolithic die with more transistors, and a full set of measured benchmark scores. The 9900X's unlocked multiplier and desktop segment designation suggest it is intended for embedded workloads requiring maximum multi-threading, while the 8500G's mobile segment label and integrated Radeon 740M graphics point toward compact or power-conscious systems.

The absence of 9900X benchmark data means no performance ranking can be assigned to it. Its percentile of 50 is listed but unsupported by any scores. Buyers seeking verified performance numbers should rely on the 8500G's recorded results, which demonstrate strong multi-threaded throughput in Cinebench R23 at 18368, Geekbench multicore at 9444, and Passmark multithread at 21610. The 9900X's architectural advantages are documented, but its actual performance remains unmeasured in this database.
