AMD Ryzen 5 7600X3D vs Intel Core Ultra 5 225T Comparison

Where Each One Wins

The benchmark data splits these two desktop processors into distinct use-case profiles. The AMD Ryzen 5 7600X3D takes 6 of the 17 head-to-head tests, while the Intel Core Ultra 5 225T takes 11. That split is not just a count, it reveals the workloads each part favors.

The AMD chip wins decisively in data compression (20.4% ahead), integer math (24% ahead), and physics simulation (41.5% ahead). It also leads in extended instructions (5.1%), random string sorting (19.3%), and multithreaded PassMark (2%). These are heavily cache-sensitive or integer-heavy workloads. The 96 MB shared L3 cache on the Ryzen 5 7600X3D appears to be the primary driver, as these tasks repeatedly access large working sets that fit within that pool.

The Intel Core Ultra 5 225T counters with wins in all six Cinebench tests, though by narrow margins (0.9% to 1%). It also dominates in floating-point math (46.5% ahead), single-thread PassMark (17.1% ahead), prime number finding (17.6% ahead), and data encryption (11.2% ahead). The floating-point gap is enormous and indicates a fundamentally different execution pipeline. The Intel part's higher boost clock (4.90 GHz vs 4.70 GHz) and newer 3 nm process likely contribute to its single-thread and FP advantages.

For gaming and general desktop use, the AMD chip's physics win (41.5%) and compression lead suggest strong real-world responsiveness. For productivity apps that rely on encryption, floating-point calculations, or lightly threaded code, the Intel part holds the edge. Neither chip dominates across every category, so the choice depends entirely on the workload mix.

Architecture Differences

The two processors come from different design philosophies. AMD uses a monolithic 6-core, 12-thread layout built on TSMC's 5 nm process with Zen 4 architecture (Raphael). The chip contains 11,270 million transistors on a 71 mm² die. Intel's Core Ultra 5 225T uses Arrow Lake-S architecture with 10 cores but only 10 threads, meaning it does not use simultaneous multithreading. It is built on TSMC's 3 nm process with 17,800 million transistors on a 243 mm² die.

The core configuration difference is stark. AMD gives every core two threads, while Intel gives each core one thread but adds four more physical cores. This explains why the Intel chip wins Cinebench multicore by about 1% despite having fewer threads: the extra physical cores compensate for the lack of SMT. The AMD chip's 96 MB shared L3 cache dwarfs Intel's 20 MB, which explains the compression and integer math wins. Intel counters with a much larger L1 (192 KB per core vs 64 KB) and L2 (3 MB per core vs 1 MB) cache.

Memory bandwidth favors Intel: 102.4 GB/s vs 83.2 GB/s, both on dual-channel DDR5. Intel also runs 20 PCIe Gen 5 lanes from the CPU, while AMD provides 24. Both support DDR5 memory, but only AMD supports ECC. Integrated graphics differ as well: AMD uses Radeon Graphics, Intel uses Arc Xe-LPG Graphics with 16 execution units. Both chips have locked multipliers and 65 W TDP. AMD uses Socket AM5, Intel uses Socket 1851. The AMD part launched in August 2024 with a $299 MSRP; the Intel part followed in December 2024 with no recorded launch price.

Head-to-Head Benchmarks

The Cinebench results are remarkably close. In Cinebench R23 multicore, the Intel chip scores 21971 against AMD's 21758, a 1% margin. Single-core R23 shows 3101 vs 3071, again 1% for Intel. The pattern repeats in R20 (9227 vs 9138 multicore, 1302 vs 1289 single-core) and R15 (2214 vs 2193 multicore, 312 vs 309 single-core). Every Cinebench test goes to Intel, but by the slimmest of margins. A 1% difference is within run-to-run noise for many systems.

The PassMark suite tells a different story. AMD's data compression score of 281665 crushes Intel's 233998, a 20.4% lead. Integer math goes to AMD at 73804 vs 59543, a 24% advantage. Physics shows AMD at 2906 vs 2053, a 41.5% gap. Random string sorting favors AMD at 34318 vs 28774 (19.3%). Extended instructions go AMD's way at 21108 vs 20083 (5.1%). Multithreaded PassMark is close, AMD 25855 vs Intel 25358 (2%).

Intel wins the remaining PassMark tests. Floating-point math is a rout: Intel scores 82751 vs AMD's 44289, a 46.5% lead. Single-thread PassMark shows Intel at 4348 vs 3605, a 17.1% gap. Prime number finding goes Intel 284 vs 234 (17.6%). Data encryption favors Intel 18289 vs 16237 (11.2%). These results indicate the Intel core architecture handles floating-point and scalar single-thread code much more efficiently, while AMD's large L3 cache accelerates memory-bound integer tasks.

The Verdict

The data shows a clear workload-based split. The AMD Ryzen 5 7600X3D is the choice for integer-heavy, cache-sensitive tasks. Its 96 MB L3 cache delivers a 24% lead in integer math, a 20.4% lead in data compression, and a 41.5% lead in physics simulation. For users running databases, compression tools, or physics engines, the AMD part provides measurable advantages.

The Intel Core Ultra 5 225T wins where floating-point and single-thread performance matter. Its 46.5% lead in floating-point math is the largest margin in the entire comparison. It also leads by 17.1% in single-thread PassMark and by 11.2% in data encryption. For spreadsheet calculations, encryption workloads, or lightly threaded applications, Intel is the stronger option.

In Cinebench, the two are essentially tied. The Intel chip wins every multicore and single-core Cinebench test, but by only 1% or less. That margin is small enough to be considered negligible in practice. The PassMark multithread test also shows a narrow AMD lead of 2%.

The overall database percentile ranks the Intel chip higher at 82 vs AMD's 77, and the average benchmark score is 30468 for Intel vs 24728 for AMD. However, that average includes the massive floating-point gap, which may not matter for all users. The AMD part's nearest rival is the AMD Ryzen 7 5700X3D (0.1% difference), while Intel's nearest rival is the Intel Core i9-11980HK (0.2% difference).

Choose the AMD Ryzen 5 7600X3D for integer-heavy, cache-sensitive workloads and physics simulation. Choose the Intel Core Ultra 5 225T for floating-point math, encryption, and single-thread performance. For general productivity, the Cinebench results indicate the two are effectively interchangeable.
