AMD Ryzen 5 7500X3D vs AMD Ryzen 7 8700G Comparison

Head-to-Head Benchmarks

The benchmark data paints a clear split between these two AMD processors. The Ryzen 7 8700G wins 9 of the 11 recorded comparisons, while the Ryzen 5 7500X3D takes the remaining 2. The margin of victory in each case tells the story of two very different design priorities.

The 8700G's largest wins come in compute-heavy workloads. In integer math, it scores 103107 against the 7500X3D's 70774, a 31.4% advantage. Floating point math shows a similar gap: 63815 versus 43594, a 31.7% lead. Data compression favors the 8700G at 386811 versus 271649, a 29.8% edge, and data encryption follows at 22842 versus 15797, a 30.8% gap. Extended instructions show 29067 versus 20455, a 29.6% difference. Random string sorting goes to the 8700G at 46025 versus 32999, a 28.3% margin.

The multithreaded PassMark score reflects the 8700G's core and thread advantage: 31690 versus 25047, a 21% lead. Single-thread performance also favors the 8700G, with 3928 versus 3494, an 11% gap.

The 7500X3D's two wins are notable for their magnitude. In find prime numbers, it scores 221 against the 8700G's 103, a 114.6% advantage. The physics test goes to the 7500X3D at 2779 versus 1647, a 68.7% lead. These results indicate that the 7500X3D's specialized cache layout delivers outsized gains in specific algorithmic patterns, even while losing most raw throughput comparisons.

The average benchmark score confirms the overall picture: the 8700G sits at 33089, while the 7500X3D reaches 44573. That average is heavily weighted by the 7500X3D's prime number and physics scores, which are extreme outliers relative to its other results. The percentile rankings place the 7500X3D at 89% of all CPUs, while the 8700G sits at 83%.

Architecture Differences

The two chips share the Zen 4 core architecture and AMD Socket AM5, but the implementation differs substantially.

The 7500X3D is built on TSMC's 5 nm process with a die size of 71 mm² and 11,270 million transistors. It belongs to the Raphael family within the 7000 series. The 8700G uses TSMC's 4 nm node, packs 25,000 million transistors into a 178 mm² die, and comes from the Phoenix line in the 8000 series. The smaller process node combined with a much larger die explains why the 8700G carries significantly more transistor count.

Cache configuration is where the 7500X3D makes its mark. Both chips use 64 KB of L1 per core and 1 MB of L2 per core, but L3 differs dramatically. The 7500X3D features 96 MB of shared L3 cache, while the 8700G has only 16 MB. That 80 MB difference in L3 is the primary driver of the 7500X3D's prime number and physics test wins, as those workloads benefit from large working sets that fit entirely in the faster cache hierarchy.

Core counts also diverge. The 7500X3D has 6 cores and 12 threads, with a base clock of 4.00 GHz and a boost clock of 4.50 GHz. The 8700G provides 8 cores and 16 threads, running at 4.20 GHz base and 5.10 GHz boost. The 8700G's higher clocks and additional cores explain its broad lead across most benchmarks, despite the 7500X3D's cache advantage.

Memory support is identical on paper: both use dual-channel DDR5 with 83.2 GB/s bandwidth. However, the 7500X3D supports ECC memory while the 8700G does not. PCIe connectivity differs as well. The 7500X3D offers Gen 5 with 24 CPU lanes, while the 8700G provides Gen 4 with 20 CPU lanes.

Integrated graphics separate these chips more than any other feature. The 7500X3D includes basic Radeon Graphics, while the 8700G carries the Radeon 780M. The 8700G also has an unlocked multiplier, enabling overclocking, whereas the 7500X3D is locked. The 8700G was released earlier with a launch MSRP of $329, while the 7500X3D launched more recently at $269.

The thermal design power is identical at 65 watts for both, which means the 8700G delivers its higher performance within the same power envelope. The 7500X3D achieves its specialized results with a 65 W TDP as well, but with fewer cores and lower clocks.

Where Each One Wins

The data shows that the 8700G dominates general computing workloads. Its 8 cores, 16 threads, and higher clock speeds translate into consistent advantages across integer math, floating point math, data compression, encryption, extended instructions, random string sorting, and multithreaded tasks. The 21% multithread lead and 11% single-thread lead confirm that the 8700G is the stronger all-around processor for everyday applications, content creation, and productivity software that scales across cores.

The 7500X3D wins in two narrowly defined scenarios. The find prime numbers test shows a 114.6% advantage, which points to workloads with heavy use of prime number generation, such as cryptography key generation or certain mathematical simulations. The physics test shows a 68.7% lead, indicating that physics simulations in scientific computing or engineering applications benefit greatly from the 96 MB L3 cache. These are not typical desktop workloads, but for users who run such tasks, the 7500X3D provides exceptional performance that the 8700G cannot match.

The 7500X3D also holds advantages in areas not directly benchmarked here. Its ECC memory support makes it suitable for workstation builds where data integrity matters. The PCIe Gen 5 connectivity provides future-proofing for high-bandwidth storage and graphics cards. The 8700G, by contrast, relies on PCIe Gen 4, which remains sufficient for most current hardware but lacks the newer standard's headroom.

The integrated graphics situation is worth noting. The 8700G's Radeon 780M is a far more capable iGPU than the basic Radeon Graphics in the 7500X3D. For systems without a discrete graphics card, the 8700G can handle light gaming and accelerated video encoding, while the 7500X3D's iGPU is limited to basic display output. This makes the 8700G a viable option for compact builds that skip a dedicated GPU, whereas the 7500X3D realistically requires a discrete card for any graphics-intensive work.

The Verdict

The benchmark results indicate that the AMD Ryzen 7 8700G is the stronger processor for the majority of computing tasks. It wins 9 of 11 head-to-head comparisons, with leads ranging from 11% in single-thread work to over 31% in integer and floating point math. Its 8 cores, 16 threads, and higher clock speeds make it the better choice for multithreaded applications, content creation, and general desktop use. The Radeon 780M integrated graphics also make it suitable for systems without a discrete GPU, and the unlocked multiplier allows for tuning.

The AMD Ryzen 5 7500X3D wins the two benchmarks where the 96 MB L3 cache provides a decisive advantage. The 114.6% lead in prime number generation and 68.7% lead in physics tests are substantial margins that cannot be ignored for users running those specific workloads. Its ECC memory support and PCIe Gen 5 connectivity add value for workstation-oriented builds, and the lower launch MSRP of $269 versus $329 reflects its position as a more specialized part.

The data suggests the choice hinges on workload. For general-purpose computing, multithreaded productivity, or builds relying on integrated graphics, the 8700G is the data-backed pick. For mathematical simulations, physics workloads, or applications that benefit from a massive L3 cache, the 7500X3D delivers results the 8700G cannot approach. The 7500X3D's lower TDP-matched performance in those specialized tests shows that cache capacity can outperform raw core count and clock speed when the software fits the cache profile.
