AMD Ryzen 5 2600X vs AMD Ryzen 5 7535U Comparison

The AMD Ryzen 5 2600X and AMD Ryzen 5 7535U are nearly identical in overall average benchmark score—223 vs. 22791, a 0.1% difference—yet they are profoundly different processors. The 2600X is a 2018 desktop chip built on the older Zen architecture, while the 7535U is a 2023 mobile processor using Zen 3+. The data shows that the 7535U wins 12 of 15 head-to-head tests, decisively outperforming the 2600X in single-threaded and multi-threaded workloads alike. However, the 2600X still claims three specific victories, including data encryption and random string sorting, where its desktop-oriented design holds a measurable edge.

Where Each One Wins

The 7535U is the clear performance leader across the vast majority of workload categories, but the 2600X is not obsolete. The 7535U wins in all the most common and demanding benchmark categories: Cinebench R15 single-core (225 vs. 163, 27.6% ahead), Geekbench single-core (1602 vs. 1250, 22% ahead), and Geekbench multi-core (6466 vs. 6153, 4.8% ahead). In PassMark tests, the 7535U dominates integer math (62109 vs. 47377, 23.7% ahead), floating-point math (33971 vs. 24270, 28.6% ahead), extended instructions (13187 vs. 7581, 42.5% ahead), and multithreaded performance (17039 vs. 13893, 18.5% ahead). It also wins in data compression (200252 vs. 198785, a slim 0.7% lead), prime number finding (50 vs. 38, 24% ahead), and physics simulation (839 vs. 695, 17.2% ahead).

The 2600X’s wins are narrower but still notable. It takes data encryption (13133 vs. 12706, 3.4% ahead) and random string sorting (22911 vs. 21267, 7.7% ahead). It also wins Cinebench R15 multi-core (1341 vs. 1330, 0.8% ahead), although this is a marginal victory. The use-case split is clear: the 7535U is the better all-rounder for most tasks, while the 2600X holds a niche advantage in specific memory-access and encryption workloads.

Architecture Differences

The two chips represent a generational leap in design philosophy. The 2600X uses the Zen (Pinnacle Ridge) architecture on a 12 nm process from GlobalFoundries, with a die size of 213 mm² and 4,800 million transistors. The 7535U uses Zen 3+ (Rembrandt) on a 6 nm process from TSMC, with a slightly smaller die at 208 mm². The transistor count for the 7535U is not listed, but the shift to 6 nm is clearly tied to its dramatically lower TDP of 28 watts compared to the 2600X’s 95 watts.

Cache configurations differ significantly. The 2600X has 96 KB of L1 cache per core, while the 7535U has 64 KB per core. Both have 512 KB of L2 per core and 16 MB of shared L3 cache, but the 2600X’s larger L1 suggests a different prefetching and data-path design. Memory support also diverges: the 2600X uses DDR4 with 46.9 GB/s bandwidth, while the 7535U uses DDR5 with 76.8 GB/s bandwidth—a 64% advantage in theoretical memory throughput. The 7535U also supports ECC memory, while the 2600X does not.

The 7535U includes integrated Radeon 660M graphics, whereas the 2600X has no integrated GPU, requiring a discrete graphics card. PCIe support is also newer on the 7535U: Gen 4 with 20 lanes versus Gen 3 with 16 lanes on the 2600X. The 7535U is a locked mobile chip (multiplier locked) on AMD Socket FP7, while the 2600X is an unlocked desktop chip on AM4. These architectural differences explain why the 7535U achieves higher clock speeds (4.55 GHz boost vs. 4.25 GHz) despite a 67-watt lower TDP.

Head-to-Head Benchmarks

The most striking gap is in Cinebench R15 single-core, where the 7535U scores 225 versus 163 for the 2600X—a 27.6% advantage. This is the largest single-core margin in the entire comparison and reflects the IPC gains from Zen to Zen 3+. The double-digit percentage leads continue across PassMark tests: extended instructions show a 42.5% lead (13187 vs. 7581), floating-point math is 28.6% ahead (33971 vs. 24270), and single-thread performance is 25.7% better (3203 vs. 2381). Even in multi-threaded tests, the 7535U’s 6-nm efficiency pays off: PassMark multithread is 18.5% higher (17039 vs. 13893), and Geekbench multi-core is 4.8% higher (6466 vs. 6153).

The 2600X’s wins are concentrated in areas where its architecture appears better optimized. In data encryption, it scores 13133 versus 12706, a 3.4% edge. In random string sorting, it scores 22911 versus 21267, a 7.7% margin. The Cinebench R15 multi-core win (1341 vs. 1330, 0.8%) is close but consistent with its desktop-oriented design. Notably, the 2600X loses the PassMark data compression test by only 0.7% (198785 vs. 200252), suggesting that the 7535U’s DDR5 memory bandwidth gives it a slight edge even in memory-sensitive tasks.

The overall benchmark score is nearly identical: the 2600X averages 22823, and the 7535U averages 22791, with a delta of just 0.1%. This places both at the 76th percentile of all CPUs, and their nearest rivals include the AMD Ryzen 5 6600U, Intel Core i5-12500H, and Intel Core Ultra 5 135U, all within 0.9% of these scores.

The Verdict

The data points decisively toward the 7535U for almost any use case. It wins 12 of 15 head-to-head benchmarks, including every major single-threaded test and most multi-threaded ones. Its 42.5% lead in extended instructions, 28.6% lead in floating-point math, and 25.7% lead in single-thread performance show a generational leap in IPC. The 7535U achieves this while consuming only 28 watts versus 95 watts, making it dramatically more efficient. It also brings modern features: DDR5 memory, ECC support, PCIe Gen 4, and integrated Radeon 660M graphics.

The 2600X is not without merit. Its wins in data encryption (3.4%), random string sorting (7.7%), and Cinebench R15 multi-core (0.8%) suggest that its older architecture retains strengths in specific memory-latency-sensitive tasks. Its unlocked multiplier and AM4 socket also make it a candidate for overclocking, which could close some gaps. However, its 12 nm process and DDR4 memory support cap its potential.

For a mobile user, the 7535U is the obvious choice: it is faster, more efficient, and includes integrated graphics. For a desktop builder with a strict need for encryption or string-sorting workloads, the 2600X offers a slight edge, but the overall benchmark scores are so close (0.1% difference) that the 7535U’s modern feature set makes it the better pick for the majority of buyers. The verdict is clear: the 7535U is the superior processor in nearly every measurable way, while the 2600X remains a viable niche option for specific desktop workloads.
