AMD Ryzen 5 7500X3D vs AMD Ryzen 5 8600G Comparison

Where Each One Wins

The benchmark split between the AMD Ryzen 5 7500X3D and the AMD Ryzen 5 8600G is heavily lopsided in raw PassMark workloads, with the 8600G taking 9 of 11 direct head-to-head comparisons. However, the two wins for the 7500X3D are dramatic and reveal a clear specialization. The 7500X3D leads in passmark_find_prime_numbers by 130.2% (221 vs 96), a massive margin that points to a workload where the extra L3 cache provides an outsized advantage. It also wins passmark_physics by 91.7% (2779 vs 1450), another cache-sensitive test. These two victories are not marginal; they are the largest deltas in the entire comparison.

The 8600G, by contrast, wins every other recorded PassMark test. Its advantages range from a narrow 1% lead in passmark_multithread (25294 vs 25047) to a 9.9% lead in passmark_single_thread (3878 vs 3494). The 8600G also wins passmark_data_compression by 7.4% (293306 vs 271649), passmark_data_encryption by 8.1% (17181 vs 15797), passmark_extended_instructions by 9.5% (22610 vs 20455), passmark_floating_point_math by 9% (47919 vs 43594), passmark_integer_math by 8.1% (77042 vs 70774), and passmark_random_string_sorting by 5.9% (35067 vs 32999).

The overall average benchmark score tells a different story. The 7500X3D posts an average of 44573, which places it at the 89th percentile of all CPUs. The 8600G averages 24089, at the 76th percentile. The 7500X3D's nearest rivals include the Intel Core Ultra X9 388H (44466, 0.2% behind), the Intel Core i9-13950HX (44342, 0.5% behind), and the AMD Ryzen AI Max 385 (44309, 0.6% behind), while the Intel Core i5-14600 (44889) sits 0.7% ahead. The 8600G's nearest rivals are clustered around mobile and desktop parts such as the AMD Ryzen 5 7540U (24188, 0.4% ahead) and the AMD Ryzen 7 8840U (23982, 0.4% behind). The 7500X3D competes in a much higher performance tier despite losing most direct tests, because its average includes the same PassMark suite as the 8600G plus additional weight from its extreme prime number and physics results.

Architecture Differences

Both processors use the Zen 4 core architecture, but they come from different families and are built on different process nodes. The 7500X3D is part of the 7000 series with the codename Raphael, manufactured on TSMC's 5 nm node. It integrates 11,270 million transistors on a 71 mm² die. The 8600G belongs to the 8000 series with the codename Phoenix, built on TSMC's 4 nm node with 25,000 million transistors on a 178 mm² die. The 8600G is the physically larger chip with more than double the transistor count.

Cache configuration is the defining difference. The 7500X3D has 64 KB of L1 per core, 1 MB of L2 per core, and a 96 MB shared L3 cache. The 8600G also has 64 KB of L1 per core and 1 MB of L2 per core, but only 16 MB of shared L3. The 7500X3D therefore has six times the L3 capacity, which explains its dominance in cache-sensitive workloads like prime number searching and physics simulation.

Clock speeds favor the 8600G. Its base clock is 4.30 GHz and its boost clock is 5.00 GHz, compared to 4.00 GHz base and 4.50 GHz boost for the 7500X3D. Both are 65 W TDP parts. The 8600G has an unlocked multiplier; the 7500X3D does not. Both use AMD Socket AM5 and support dual-channel DDR5 with 83.2 GB/s of memory bandwidth. PCIe support differs: the 7500X3D offers Gen 5 with 24 lanes (CPU only), while the 8600G offers Gen 4 with 20 lanes (CPU only).

Integrated graphics differ significantly. The 7500X3D includes basic Radeon Graphics, while the 8600G includes the Radeon 760M. ECC memory support is present on the 7500X3D but absent on the 8600G. The 7500X3D launched on 2025-11-11 with a launch MSRP of $269. The 8600G launched on 2024-01-07 with a launch MSRP of $229. The 7500X3D part number is 100-000001904; the 8600G part number is 100-000001237.

Head-to-Head Benchmarks

The largest single win in the entire comparison belongs to the 7500X3D in passmark_find_prime_numbers. Its score of 221 is 130.2% higher than the 8600G's 96. This is a workload where the 96 MB L3 cache provides a decisive benefit, and the margin is so large that it dominates the narrative of the comparison. The second 7500X3D win is passmark_physics, where it scores 2779 versus 1450, a 91.7% advantage. Both of these tests are known to be sensitive to cache capacity, and the data confirms that the 7500X3D's larger L3 more than compensates for its lower clocks in these specific scenarios.

The 8600G's strongest win is in passmark_single_thread, where it scores 3878 against 3494, a 9.9% lead. This is consistent with its higher boost clock of 5.00 GHz versus 4.50 GHz. The 8600G also leads in passmark_extended_instructions by 9.5% (22610 vs 20455), passmark_floating_point_math by 9% (47919 vs 43594), passmark_data_encryption by 8.1% (17181 vs 15797), passmark_integer_math by 8.1% (77042 vs 70774), passmark_data_compression by 7.4% (293306 vs 271649), passmark_random_string_sorting by 5.9% (35067 vs 32999), and passmark_multithread by 1% (25294 vs 25047).

The passmark_multithread result is notable for how close it is. Only 247 points separate the two processors out of a total score of about 25,000. Despite the 7500X3D having six times the L3 cache, the 8600G's higher clocks and newer process node are enough to edge it out in aggregate multithreaded throughput. The single-thread result is similarly one-sided toward the 8600G, with a 384-point gap.

The average benchmark scores place the 7500X3D far above the 8600G in the overall percentile ranking. The 7500X3D sits at the 89th percentile of all CPUs with an average score of 44573, while the 8600G sits at the 76th percentile with 24089. The 7500X3D's nearest rivals, such as the Intel Core Ultra X9 388H and the Intel Core i9-13950HX, are all within 0.6% of its average, indicating that it performs in a much higher tier than the 8600G's rivals, which include the AMD Ryzen 5 7540U and the Intel Core i5-13400. The 8600G's average is roughly 46% lower than the 7500X3D's, a gap driven largely by the prime number and physics results, which are weighted heavily in the overall average despite the 8600G winning most individual tests.
